A slide bush 175B is slidably held in the arc-shaped elongated hole 175. The end of the first rod 115 is connected to the slide bush 175B, and the fully open latch release lever 170 and a motor power relay lever 160 described later are connected by the first rod 115.

  The second lever arm 172 of the fully open latch release lever 170 is formed with an interlocking contact piece 174 that protrudes in the first rotation direction and has a tip bent toward the base plate 101 (see FIG. 10). When the fully open latch release lever 170 and the inside input lever 140 are both at the origin position, the interlocking contact piece 174 is in contact with or close to the end bent portion 141K of the inside input lever 140. When the interior door handle 18 is closed, the inside input lever 140 is rotated in the second rotational direction from the origin position in response to the operation force, and the end bending portion 141K pushes the interlocking contact piece 174. That is, the fully open latch release lever 170 is pushed by the inside input lever 140 and integrally rotates in the second rotation direction from the origin position. Then, the open cable 93W connected to the first lever arm 171 of the fully open latch release lever 170 is pulled toward the remote control device 100, and the fully open latch of the slide door 90 by the fully open door latch device 10C is released.

  As shown in FIG. 10, among the plurality of levers 120, 130, and 170 pivotally supported by the support shaft 111 on the front side of the base plate 101, the relay rotation lever 120 pivotally supported at a position closest to the base plate 101 is Lever arms 121, 122, 123 protrude from the support shaft 111 in three directions. Specifically, as shown in FIG. 11, a first lever arm 121 projecting from the support shaft 111 toward the rear end of the slide door 90, a second lever arm 122 projecting upward from the support shaft 111, and a support And a third lever arm 123 protruding downward from the shaft 111.

  From the front end position of the first lever arm 121 in the first rotation direction, a spring locking protrusion 121T is extended outward in the rotation radial direction, and the spring locking protrusion 121T, the base plate 101, and the like. The relay turning lever 120 is urged in the second turning direction by the coil spring 129 connecting the two.

  An arc-shaped long hole 124 centering on the support shaft 111 is formed in a portion near the tip of the first lever arm 121, and a slide bush 124B is slidably held in the arc-shaped long hole 124. ing. The end of the second rod 116 is connected to the slide bush 124B, and the relay turning lever 120 and a motor power relay lever 160 described later are connected by the second rod 116.

  A switch contact piece 121K (see FIG. 10) is cut and raised toward the base plate 101 from an intermediate position between the arc-shaped elongated hole 124 and the support shaft 111 in the first lever arm 121 of the relay turning lever 120. . Corresponding to the switch contact piece 121 </ b> K, a communication window 103 is formed through the base plate 101, and the switch contact piece 121 </ b> K protrudes from the connection window 103 to the back side of the base plate 101. When the relay turning lever 120 is turned in the first turning direction from the origin position shown in FIG. 5, the switch contact piece 121K is a switch SW1 for detecting the opening operation provided on the back surface of the base plate 101 (FIG. 6). Contact) to turn it on.

  Of the relay rotation lever 120, the second lever arm 122 protruding upward from the support shaft 111 overlaps the back surface of the fully-closed latch release lever 130 described later. An L-shaped long hole 125 is formed through the second lever arm 122. As shown in FIG. 12, the L-shaped long hole 125 has an L-shaped first side path 125A extending in the rotational radius direction, and the L-shaped first side path 125A from the end away from the support shaft 111. It consists of an L-shaped second side path 125B extending in two rotational directions. The lock pin 134 passes through the L-shaped long hole 125. In addition, the second lever arm 122 is formed with an interlocking contact piece 128 that protrudes in the first rotation direction and whose tip is bent toward the fully closed latch release lever 130 side (the side away from the base plate 101).

  A third lever arm 123 protruding downward from the support shaft 111 in the relay pivot lever 120 is formed with a child lock elongated hole 126 extending in the pivotal radial direction, and the child lock elongated hole 126 is child-locked. The pin 127 penetrates. The child lock pin 127 is prevented from coming off with respect to the child lock long hole 126, and can reciprocate with a pair of side sides extending in the longitudinal direction of the child lock long hole 126 as a guide. Corresponding to the child lock pin 127, a communication window 104 is formed through the base plate 101, and one end of the child lock pin 127 protrudes from the communication window 104 to the back side of the base plate 101.

  In order to reciprocate the child lock pin 127 within the child lock long hole 126, a child lock operation lever 190 is provided on the front surface of the base plate 101. As shown in FIG. 11, the child lock operation lever 190 is rotatable about the lever shaft 114. The lever shaft 114 is disposed closer to the front end of the slide door 90 than the support shaft 111.

  As shown in FIGS. 11 and 12, the child lock operation lever 190 includes an operation arm 191 that protrudes from the lever shaft 114 toward the front end side of the slide door 90 and a pin that protrudes toward the rear end side of the slide door 90. And a connecting arm 192. The operation arm 191 has a T-shape, and a tip portion thereof is exposed from the front end surface of the slide door 90. On the other hand, the pin connecting arm 192 has an arc shape and is overlapped with the front surface of the third lever arm 123 in the relay rotation lever 120. An arc-shaped long hole 193 centering on the support shaft 111 is formed through the pin connecting arm 192, and the child lock pin 127 passes through the arc-shaped long hole 193 so as to reciprocate.

  When the operation arm 191 of the child lock operation lever 190 is moved downward to the “unlocked position” shown in FIG. 11, the pin connecting arm 192 is lifted so that the child lock pin 127 is inserted into the child lock long hole 126. It is arranged at the end near the support shaft 111. At this time, as shown in FIG. 6, the child lock pin 127 is disposed in the rotation region of the inside input lever 140 (specifically, the third lever arm 143), and therefore, the child lock pin 127 is interposed via the child lock pin 127. The inside input lever 140 and the relay rotation lever 120 are coupled so as to be integrally rotatable in a first rotation direction (counterclockwise direction in FIG. 6). In other words, it is possible to transmit the operation force generated by opening the interior door handle 18 from the inside input lever 140 to the relay turning lever 120. This state is the “unlocked state” of the child lock.

  On the other hand, when the operation arm 191 of the child lock operating lever 190 is moved upward from the position shown in FIG. 11 to the “locking position”, the pin connecting arm 192 is lowered, so that the child lock pin 127 is locked. The long hole 126 is disposed at an end portion on the side away from the support shaft 111. At this time, since the child lock pin 127 is disposed outside the rotation area of the inside input lever 140 (specifically, the third lever arm 143), the inside input lever 140 and the relay rotation lever 120 cannot be interlocked. Separated. That is, the operating force due to the opening operation of the vehicle interior door handle 18 is blocked between the inside input lever 140 and the relay rotation lever 120. This state is the “locked state” of the child lock.

  As shown in FIG. 6, an arc-shaped positioning window 105A centering on the lever shaft 114 is formed through the base plate 101, and a positioning protrusion 194 protruding from the back surface of the operation arm 191 enters the positioning window 105A. Yes. The rotation range of the child lock operation lever 190 is restricted by the positioning projections 194 coming into contact with both longitudinal ends of the positioning window 105A.

  As shown in FIG. 10, a fully closed latch release lever 130 is pivotally supported between the fully open latch release lever 170 and the relay rotation lever 120 in the axial direction of the support shaft 111. The fully-closed latch release lever 130 includes a first lever arm 131 and a second lever arm 132 that protrude from the support shaft 111 in substantially opposite directions. The first lever arm 131 extends downward from the support shaft 111 and is bent in a crank shape at an intermediate portion. Cable connecting hooks 137 and 137 are formed at the tip of the first lever arm 131, and open cables 91W and 92W are connected to the cable connecting hooks 137 and 137, respectively. That is, the fully closed latch release lever 130 and the fully closed door latch device 10A are connected via the open cable 91W, and the fully closed latch release lever 130 and the fully closed door latch device 10B are connected via the open cable 92W. The open cables 91 </ b> W and 92 </ b> W extend from the cable connection hooks 137 and 137 toward the rear of the slide door 90, and are disposed substantially parallel to the open cable 93 </ b> W connected to the fully open latch release lever 170.

  Of the fully-closed latch release lever 130, the second lever arm 132 extends obliquely upward from the support shaft 111 toward the rear end side of the slide door 90. The second lever arm 132 is disposed so as to overlap the front surface of the second lever arm 122 of the relay turning lever 120 (see FIG. 12), and an I-shaped long hole 133 extending in the turning radial direction is formed to penetrate therethrough. Has been. The I-shaped long hole 133 can be overlapped with the L-shaped first side path 125A of the relay rotation lever 120 when both the fully-closed latch release lever 130 and the relay rotation lever 120 are at the origin position. A common lock pin 134 passes through the long mold hole 133 and the long L hole 125. The lock pin 134 is secured to the I-shaped long hole 133, and can reciprocate in the I-shaped long hole 133 using a pair of sides extending in the longitudinal direction of the I-shaped long hole 133 as a guide. ing.

  Here, the second lever arm 132 of the fully-closed latch release lever 130 is formed with an interlocking contact piece 135 protruding in the first rotation direction, and the interlocking contact piece 135 is connected to the relay rotation lever 120. The second lever arm 122 can be brought into contact with the interlocking contact piece 128. Accordingly, the fully-closed latch release lever 130 receives the biasing force of the coil spring 129 (see FIG. 11) via the relay rotation lever 120 and is biased in the second rotation direction together with the relay rotation lever 120. ing. Then, the first lever arm 131 of the fully-closed latch release lever 130 abuts against the stopper 108 cut and raised from the base plate 101, so that the fully-closed latch release lever 130 and the relay turning lever 120 are in FIG. It is positioned at the indicated origin position.

  As shown in FIG. 5, a locking actuator 187 for moving a lock pin 134 within an I-shaped long hole 133 on the opposite side of the front surface of the base plate 101 with the door lock knob 16 therebetween and the support shaft 111. Is provided. Further, a locking lever 180 for applying the power of the locking actuator 187 to the lock pin 134 is provided on the front surface of the base plate 101 (see FIGS. 11 and 12).

  As shown in FIG. 6, the lever shaft 113, which is the rotation center of the locking lever 180, is disposed at a position opposite to the lever shaft 114 with the support shaft 111 interposed therebetween. As shown in FIG. 11, the locking lever 180 includes a first lever arm 181 extending from the lever shaft 113 toward the locking actuator 187 and a second lever arm 182 extending from the lever shaft 113 toward the lock pin 134. Have. The second lever arm 182 is overlapped on the back side of the second lever arm 122 of the relay rotation lever 120 described above, and an arc-shaped long hole 183 centering on the support shaft 111 is formed therethrough. The arc-shaped elongated hole 183 can be overlapped with the I-shaped elongated hole 133 and the L-shaped elongated hole 125, and a lock pin 134 penetrating the I-shaped elongated hole 133 and the L-shaped elongated hole 125 is further arc-shaped. It penetrates the long hole 183.

  The locking actuator 187 has a door lock motor 187M and an output lever 187R that rotates by receiving the power of the door lock motor 187M. As shown in FIG. 11, the distal end portion of the output lever 187R is overlapped with the distal end portion of the first lever arm 181 of the locking lever 180 from the front side and protrudes from the output lever 187R toward the first lever arm 181. The pin 188A is connected to a long hole 185 penetratingly formed in the first lever arm 181 (see FIG. 6). Further, a pin 188B protrudes from the tip of the output lever 187R on the side opposite to the pin 188A, and the output lever 187R and the door lock knob 16 are connected by the pin 188B (see FIG. 12). That is, the output lever 187R is rotated by both the power of the door lock motor 187M and the manual operation (vertical movement operation) of the door lock knob 16.

  As the output lever 187R is rotated, the locking lever 180 is rotated about the lever shaft 113, and the lock pin 134 is located on the support shaft 111 side of the I-shaped long hole 133 of the fully-closed latch release lever 130. It moves between the coupling position and the coupling release position on the L-type second side path 125B side in the I-shaped long hole 133.

  For example, as shown in FIG. 11, when the door lock is locked when the door lock is in the “released state”, the locking lever 180 rotates about the lever shaft 113 in the first rotation direction to lock the door lock. The pin 134 becomes a coupling release position on the side away from the support shaft 111 in the I-shaped long hole 133. In this coupling release position, the lock pin 134 can move in the L-shaped second side path 125B. Therefore, even if the relay rotation lever 120 rotates in the first rotation direction, the fully-closed latch release lever 130 does not move. It remains stopped at the origin position (see FIG. 5). That is, the transmission of force from the relay rotation lever 120 to the fully closed latch release lever 130 is interrupted, and it becomes impossible to release the fully closed latches by the fully closed door latch devices 10A and 10B. This state is the “locked state” of the door lock.

  On the other hand, when the unlocking operation of the door lock is performed from the locked state, the locking lever 180 rotates in the second rotation direction around the lever shaft 113, and the lock pin 134 is the support shaft of the I-shaped long hole 133. It moves to the coupling position closer to 111 (state shown in FIG. 11). In this coupling position, the lock pin 134 is disposed in the L-shaped first side path 125A, and thus the fully-closed latch release lever 130 and the relay rotation lever 120 are coupled to each other so as to be integrally rotatable. . That is, transmission of force from the relay rotation lever 120 to the fully-closed latch release lever 130 is possible.

  Here, as shown in FIGS. 6 and 12, the base plate 101 is formed with a circular positioning window 105 </ b> B centering on the lever shaft 113, and the positioning protrusion 186 protruding from the locking lever 180 toward the base plate 101. However, it has entered the positioning window 105B. Thereby, the rotation range of the locking lever 180 is restricted.

  As shown in FIGS. 11 and 12, a switch contact piece 184 protruding toward the first rotation direction and having a side edge protruding toward the base plate 101 is provided at the tip of the first lever arm 181 of the locking lever 180. Is formed. Corresponding to the switch contact piece 184, a connecting window 106 is formed through the base plate 101, and the switch contact piece 184 protrudes from the connecting window 106 to the back side of the base plate 101. Then, when the door lock is locked by the door lock knob 16 or the locking actuator 187, the locking lever 180 rotates about the lever shaft 113 in the first rotation direction (counterclockwise direction in FIG. 6). Thus, the switch contact piece 184 turns on the position switch SW3 provided on the back surface of the base plate 101. The lock / unlock state of the door lock is detected by turning on / off the position switch SW3.

  As shown in FIG. 6, a harness HN is laid on the back surface of the base plate 101 to which the switches SW1 to SW3 are attached, and three cables CA, CA, CA branched from the tip of the harness HN are provided. Each is connected to the switches SW1 to SW3. The connector CN1 provided at the end of the harness HN is disposed between a release motor 60 and a motor power relay lever 160, which will be described below, and opens below the remote control device 100.

  As shown in FIG. 5, a release motor 60 is attached via a bracket 61 below the locking actuator 187 in the front surface of the base plate 101. In the release motor 60, for example, one of the switches SW1 and SW2 is turned on (the interior door handle 18 or the exterior door handle 17 is operated), and the door latch by the fully open door latch device 10C or the fully closed door latch devices 10A and 10B is released. This is the first operating condition, and until the power slide device starts operating (the slide door 90 starts electric sliding), the door latch devices 10A, 10B, and 10C are fully closed or fully opened. Keep in the released state.

  The release motor 60 has a second operation that the door lock of the slide door 90 is unlocked (position switch SW3 is off) and remote operation (operation of a remote control key or a door opening / closing button in the vehicle) is performed. Acting as a condition, the motor power relay lever 160 is rotationally driven to release the fully-closed latch or the fully-opened latch by the door latch devices 10A, 10B, 10C by the motor power.

  Here, as shown in FIG. 5, the release motor 60 and the door lock motor 187M are both arranged in front of the base plate 101 and arranged side by side at the rear end side position of the slide door 90 in the base plate 101. Yes. Further, the connector CN2 provided in the release motor 60 and the connector CN3 provided in the door lock motor 187M are opened in the same direction (specifically, obliquely below the slide door 90). In other words, the connectors CN2 and CN3 are aligned so that the fitting direction with the connection partner (for example, cable with connector) is the same.

  Of the base plate 101, the outer side of the rotation region of each lever 120, 130, 140, 170 supported by the support shaft 111, specifically, the front end side position of the slide door 90 relative to the release motor 60 and the support shaft A support pin 112 is provided at a position below 111. As shown in FIG. 9, the support pin 112 passes through the lever shaft holes 160 </ b> A and 150 </ b> B of the outside input lever 150 and the motor power relay lever 160, and prevents the support pin 112 from being removed from the base shaft hole 101 </ b> B formed through the base plate 101. It is squeezed to the state.

  The outside input lever 150 is overlapped on the back surface of the motor power relay lever 160 and protrudes in the opposite direction (specifically, the front-rear direction of the slide door 90) from the support pin 112 (lever shaft hole 150A). A pair of lever arms 151 and 152 are provided. A bush 154 is attached to the first lever arm 151 that protrudes toward the front end side of the slide door 90 out of the pair of lever arms 151 and 152, and extends from the exterior door handle 17 to the bush 154. A third rod 117 is connected. In addition, an interlocking contact piece 153 that is bent toward the motor power relay lever 160 side (the side away from the base plate 101) is formed at the tip of the second lever arm 152 (see FIG. 5).

  As shown in FIG. 5, the motor power relay lever 160 includes a first lever arm 161, a second lever arm 162, and first and second rod couplings that protrude in different directions from the support pin 112 (lever shaft hole 160 </ b> A). Projections 163 and 164 are provided. The first lever arm 161 extends obliquely downward from the support pin 112 and bends at the tip to extend in the first rotation direction. The support pin 112 is centered on the portion extending in the first rotation direction. The arc-shaped long hole 165 is formed through.

  The second lever arm 162 is disposed so as to protrude from the support pin 112 to the rear end side of the slide door 90 and overlap the front surface of the second lever arm 152 in the outside input lever 150. The first and second rod connecting protrusions 163 and 164 are disposed so as to protrude from the support pin 112 to the front end side of the slide door 90 and overlap the front surface of the first lever arm 151 in the outside input lever 150. The motor power relay lever 160 is biased by the torsion coil spring 167 in the first rotation direction about the support pin 112.

  An interlocking contact piece 153 formed on the outside input lever 150 can contact the side surface of the second lever arm 162 of the motor power relay lever 160. As a result, the outside input lever 150 receives the biasing force of the torsion coil spring 167 via the motor power relay lever 160 and is biased in the first rotation direction together with the motor power relay lever 160. Then, the interlocking contact piece 153 is always in contact with the stopper 109 bent and raised from the edge of the base plate 101, so that the motor power relay lever 160 and the outside input lever 150 are positioned at the origin position shown in FIG. ing. The outside input lever 150 and the motor power relay lever 160 are positioned at a rotation end position away from the origin position in the second rotation direction by contacting the stopper 110 cut and raised from the base plate 101.

  Of the first and second rod connecting protrusions 163 and 164 provided in the motor power relay lever 160, the first rod connecting protrusion 163 close to the first lever arm 161 is connected to the first rod connecting protrusion 163 via the bush 168. The rod 115 is connected. In addition, the second rod 116 is connected to the second rod connecting protrusion 164 near the second lever arm 162 in the motor power relay lever 160 via the bush 169. That is, the motor power relay lever 160 and the fully open latch release lever 170 are connected by the first rod 115, and the motor power relay lever 160 and the relay rotation lever 120 are connected by the second rod 116.

  A slide bush 165B is slidably supported in an arc-shaped elongated hole 165 formed through the first lever arm 161 of the motor power relay lever 160, and a fourth rod 118 extending from the release motor 60 to the slide bush 165B. Are connected. The power of the release motor 60 is applied to the motor power relay lever 160 via the fourth rod 118, and only the motor power relay lever 160 rotates in the second rotation direction with the outside input lever 150 stopped at the origin position. Driven.

  The operation of remote control device 100 will be described based on the configuration so far. In the following description of the operation, it is assumed that both the child lock and the door lock are in the “unlocked state”.

[Operations on the door handle outside the vehicle]
When the outside door handle 17 is operated while the slide door 90 is fully opened latched by the fully opened door latch device 10C, the outside input lever 150 is pushed by the third rod 117 and the second time from the origin position around the support pin 112. The motor power relay lever 160 is also integrally rotated in the second rotation direction by rotating in the movement direction and being pushed by the outside input lever 150. Then, the first rod 115 is pulled to the outside input lever 150 side, and the fully open latch release lever 170 rotates in the second rotation direction from the origin position around the support shaft 111. As a result, the open cable 93W is pulled toward the remote control device 100, the fully open latch of the slide door 90 by the fully open door latch device 10C is released, and the slide door 90 can be closed.

  Here, when the motor power relay lever 160 rotates in the second rotation direction, the second rod 116 is also pulled toward the motor power relay lever 160, and the relay rotation lever 120 and the fully-closed latch release lever 130 are connected to the support shaft. Rotate in the first rotation direction from the origin position around 111. Then, the switch contact piece 121K (see FIG. 10) provided in the relay rotation lever 120 turns on the switch SW1, the first operating condition of the release motor 60 is established, and the release motor 60 operates. Then, the fourth rod 118 is pulled toward the release motor 60, and the motor power relay lever 160 is held at the rotation end position away from the origin position in the second rotation direction. As a result, even if the hand is released from the outside door handle 17 and the operating force is lost and the outside input lever 150 returns to the origin position (the position shown in FIGS. 5 and 6), the power slide device starts to operate (slide Until the door 90 starts electric sliding in the closing direction), the fully open lock release lever 170 is held at the rotation end position away from the origin position in the second rotation direction by the power of the release motor 60, The release state can be maintained.

  When the outside door handle 17 is operated while the slide door 90 is fully closed by the fully closed door latch devices 10A and 10B, the outside input lever 150 and the motor power relay lever 160 are moved in the second rotational direction from the origin position. The second rod 116 is pulled toward the outside input lever 150 side. Then, the relay turning lever 120 and the fully-closed latch release lever 130 turn in the first turning direction from the origin position, and the fully-closed latches by the fully-closed door latch devices 10A and 10B are released. At this time, the switch contact piece 121K (see FIG. 10) of the relay turning lever 120 turns on the switch SW1, the first operating condition is established, and the release motor 60 is operated.

  Then, the motor power relay lever 160 is held at the rotation end position away from the origin position in the second rotation direction by the power of the release motor 60, and the relay rotation lever 120 and the fully closed latch release lever 130 are moved from the origin position to the first position. It is held at a rotation end position separated in one rotation direction. As a result, even if the hand is released from the outside door handle 17 and the operating force is lost and the outside input lever 150 returns to the origin position, the power slide device starts operating (the slide door 90 starts electric sliding in the opening direction). ), The release state of the fully-closed latch can be maintained by the power of the release motor 60.

[Remote operation (operation on the remote control key or door opening / closing button in the car)]
When the remote operation is performed, the second operating condition is established, the release motor 60 is operated, and the fourth rod 118 is pulled toward the release motor 60 side. Then, the motor power relay lever 160 rotates in the second rotation direction from the origin position while leaving the outside input lever 150 at the origin position. Then, the fully-closed latch release lever 130 rotates in the first rotation direction from the origin position, and the fully-open latch release lever 170 rotates in the second rotation direction from the origin position. Thereby, both the fully-closed door latch devices 10A and 10B and the fully-open door latch device 10C perform the latch release operation.

[Closing operation for the interior door handle]
When the sliding door 90 is fully opened and latched by the fully opened door latch device 10C, when the in-car door handle 18 is closed, the bent end portion 141K of the inside input lever 140 pushes the interlocking contact piece 174K of the fully opened latch release lever 170, Both levers 140 and 170 are integrally rotated in the second rotation direction from the origin position around the support shaft 111. Then, the open cable 93W connected to the full-open latch release lever 170 is pulled toward the remote control device 100, so that the full-open latch of the slide door 90 by the full-open door latch device 10C is released, and the slide door 90 can be closed.

  When the interior door handle 18 is closed, the third lever arm 143 of the inside input lever 140 moves in a direction away from the child lock pin 127 (clockwise direction in FIG. 6). The follower of the rotating lever 120 is prevented. Further, when the fully open latch release lever 170 is rotated in the second rotation direction in response to the operation force from the inside input lever 140, the slide bush 175B connected to the first rod 115 moves within the arc-shaped elongated hole 175. Thus, the transmission of the operating force is interrupted, so that the follower of the motor power relay lever 160 due to the rotation of the fully open latch release lever 170 is prevented. That is, the operation force by the closing operation of the vehicle interior door handle 18 is selectively given to the full-open latch release lever 170 out of the full-open latch release lever 170 and the full-close latch release lever 130. Therefore, in the closing operation with respect to the in-vehicle door handle 18, the fully open door latch device 10C is merely unlatched by the operating force, and the fully closed door latch devices 10A and 10B are not latched.

  When the inside input lever 140 rotates from the origin position in the second rotation direction, the third lever arm 143 turns on the switch SW2 (see FIG. 6) and the first operating condition is satisfied, and the release motor 60 is satisfied. Operates. Then, the fourth rod 118 is pulled toward the release motor 60, and the motor power relay lever 160 is rotationally driven from the origin position in the second rotation direction. The first rod 115 is pulled toward the motor power relay lever 160 by the rotation of the motor power relay lever 160, and the fully open latch release lever 170 is held at the rotation end position away from the origin position in the second rotation direction. As a result, even if the hand is released from the vehicle interior door handle 18 and the operating force is lost, and the inside input lever 140 returns to the origin position (position shown in FIGS. 5 and 6), the power slide device starts to operate (slide door). The release state of the fully opened latch can be maintained by the power of the release motor 60 until 90 starts electric sliding in the closing direction.

[Opening operation for the interior door handle]
When the interior door handle 18 is opened when the sliding door 90 is fully closed and latched by the fully closed door latch devices 10A and 10B, the inside input lever 140 receives the operating force from the origin position in the first rotation direction. When the third lever arm 143 of the inside input lever 140 pushes the child lock pin 127, the relay rotation lever 120 rotates from the origin position in the first rotation direction. Since the relay turning lever 120 and the fully-closed latch release lever 130 are coupled to each other by a lock pin 134 so as to be integrally rotatable, the fully-closed latch release lever 130 also turns from the origin position in the first turning direction, and the open cable 91W and 92W are pulled toward the remote control device 100 side. Thereby, the fully-closed latch of the slide door 90 by the fully-closed door latch devices 10A and 10B is released, and the slide door 90 can be opened.

  When opening the interior door handle 18, the first lever arm 141 of the inside input lever 140 is away from the second lever arm 172 (interlocking contact piece 174) of the fully opened latch release lever 170 (clockwise direction in FIG. 5). ), The follower of the fully open latch release lever 170 due to the rotation of the inside input lever 140 is prevented. When the relay rotation lever 120 (and the fully closed latch release lever 130) rotates in the first rotation direction as the inside input lever 140 rotates, the slide bush 124B connected to the second rod 116 is circular. Since the transmission of the operating force is interrupted by moving within the arc-shaped elongated hole 124, the follower of the motor power relay lever 160 due to the rotation of the relay rotation lever 120 (and the fully closed latch release lever 130) is prevented. That is, the operating force by the opening operation of the vehicle interior door handle 18 is selectively given to the fully-closed latch release lever 130 out of the fully-open latch release lever 170 and the fully-closed latch release lever 130. Therefore, in the opening operation with respect to the in-vehicle door handle 18, the fully-closed door latch devices 10 </ b> A and 10 </ b> B are merely latch-released by the operating force, and the fully-open door latch device 10 </ b> C is not latched.

  As the inside input lever 140 turns in the first turning direction, the second lever arm 142 of the inside input lever 140 turns on the switch SW1 to establish the first operating condition, and the release motor 60 operates. To do. Then, the motor power relay lever 160 is driven to rotate in the second rotation direction around the support pin 112 by the motor power, and the relay rotation lever 120 connected by the second rod 116 and the fully-closed latch release lever 130. Is held at the rotation end position away from the origin position in the first rotation direction. As a result, even if the hand is released from the in-car door handle 18 and the operating force is lost and the inside input lever 140 returns to the home position, the power slide device starts to operate (the slide door 90 starts electric sliding in the opening direction). Until this is done, the fully closed latch can be maintained in the released state by the motor power of the release motor 60.

[Sliding door opening operation when locked]
Even when the sliding door 90 is fully closed and the door lock is in the “locked state” (the lock pin 134 is in the coupling release position), the opening operation of the interior door handle 18 or the exterior door handle 17 described above is performed. The transmission of force between the relay rotation lever 120 and the fully-closed latch release lever 130 is interrupted. Further, even if the remote operation is performed, the second operating condition of the release motor 60 is not satisfied. Therefore, the sliding door 90 cannot be opened by any operation.

  Further, when the sliding door 90 is fully closed and the child lock is in the “locked state”, the force is transmitted from the inside input lever 140 to the relay turning lever 120 even if the interior door handle 18 is opened. Since it is blocked, it is impossible to open the sliding door 90. However, even if the child lock is in the locked state, if the door lock is in the “unlocked state”, the slide door 90 can be opened by the operation of the above-described vehicle exterior door handle 17 or the remote operation.

  The operation of the remote control device 100 has been described above. Next, the support structure of the rotating lever by the support shaft 111 of the remote control device 100 will be described. As shown in FIGS. 8 and 10, the support shaft 111 is inserted from a front side of the base plate 101 into a circular base shaft hole 101 </ b> A formed through the base plate 101. The distal end portion of the support shaft 111 protrudes toward the back side of the base plate 101, and the inside input lever 140 is fixed to the distal end portion so as to be integrally rotatable. As shown in FIG. 10, the inside input lever 140 is formed with a non-circular (for example, a shape having a two-sided width) lever shaft hole 140 </ b> A. It has the same non-circular shape as the shaft hole 140A. And the front-end | tip part of the support shaft 111 is crimped in the retaining state in the state in which the front-end | tip part of the support shaft 111 and the lever shaft hole 140A of the inside input lever 140 were fitted so that integral rotation was possible (refer FIG. 8). . That is, the inside input lever 140 transmits the operation force for the in-vehicle door handle 18 to the fully-closed latch release lever 130 and the fully-open latch release lever 170, and the other levers 120 and 130 supported by the common support shaft 111. 170 and a sleeve 200 to be described later, and further, the support shaft 111 is prevented from being detached from the base plate 101. The inside input lever 140 corresponds to the “input lever”, “third rotation lever”, and “prevention plate” of the present invention.

  A shaft-side flange 111 </ b> F (corresponding to the “shaft large diameter portion” of the present invention) projecting in a disk shape is integrally formed at an intermediate portion in the axial direction of the support shaft 111. A lower end portion of the in-vehicle door handle 18 is fixed to the base end side of the support shaft 111 that is farther from the base plate 101 than the shaft side flange 111F (see FIG. 7). The support shaft 111 passes through the front surface of the base plate 101 and the peripheral edge of the through hole overlaps with the shaft-side flange 111F, and a retaining cover 119 that prevents the support shaft 111 from coming off from the front side of the base plate 101 is fixed. (See FIG. 9).

  A cylindrical sleeve 200 (see FIG. 10) is fitted to the support shaft 111 on the tip side (base plate 101 side) from the shaft side flange 111F. The sleeve 200 is inserted from the front end side of the support shaft 111 and is abutted against the shaft side flange 111F, and is sandwiched between the shaft side flange 111F and the inside input lever 140. As shown in FIG. 8, the relay turning lever 120, the fully-closed latch release lever 130, and the fully-open latch release lever 170 are rotatably supported on the outer sides of both ends of the sleeve 200. The winding portion of the torsion coil spring 19 is loosely fitted. The sleeve 200 is made of, for example, resin (specifically, made of fluororesin), and is rotatable relative to the support shaft 111.

  As shown in FIG. 8, a first sleeve small-diameter portion 201 and a second sleeve small-diameter portion 202 having a stepped outer diameter are formed at both ends in the axial direction of the sleeve 200. A second sleeve small-diameter portion 202 provided on the distal end side of the support shaft 111 is rotatably inserted into a base shaft hole 101A formed in the base plate 101, and is prevented from being detached from the distal end portion of the support shaft 111. It is abutted against the fixed inside input lever 140 (specifically, the periphery of the lever shaft hole 140A).

  An intermediate portion in the axial direction of the sleeve 200 is a sleeve large-diameter portion 203 whose diameter is increased stepwise with respect to both end portions (first and second sleeve small-diameter portions 201 and 202). Step portions 204 and 205 perpendicular to the axial direction of the sleeve 200 are formed between the portion 203 and the first and second sleeve small diameter portions 201 and 202. Further, the sleeve 200 is integrally formed with a disk-like sleeve-side flange 203F by expanding the boundary portion of the sleeve large-diameter portion 203 with the first sleeve small-diameter portion 201 in a stepped shape. The sleeve side flange 203F and the shaft side flange 111F have substantially the same diameter.

  The second sleeve small diameter portion 202 of the sleeve 200 is inserted into a circular lever shaft hole 120A (see FIG. 10) penetratingly formed in the relay rotation lever 120 so that the relay rotation lever 120 can be rotated. I support it. Here, as described above, the sleeve 200 is sandwiched between the inside input lever 140 and the shaft-side flange portion 111F with both end portions abutted against each other. Therefore, the sleeve 200 has a large diameter portion 203 (step portion 205). And the inside input lever 140 are formed with a holding groove whose axial width of the second sleeve small diameter portion 202 is the groove width. The axial length of the second sleeve small-diameter portion 202 depends on the design plate thickness of the base plate 101 (specifically, the peripheral portion of the base shaft hole 101A) and the relay rotation lever 120 (specifically, the peripheral portion of the lever shaft hole 120A). The dimension is the sum of the design plate thickness and the axial clearance set to smoothly rotate the relay rotation lever 120. The peripheral edge of the base shaft hole 101A of the base plate 101 and the relay rotation lever 120 The peripheral edge portion of the lever shaft hole 120A is sandwiched between the inside input lever 140 and the sleeve large diameter portion 203 (stepped portion 205) from the axial direction. Thereby, the movement of the relay rotation lever 120 and the base plate 101 in the axial direction with respect to the support shaft 111 is restricted. The relay turning lever 120 corresponds to the “second turning lever” of the present invention.

  As shown in FIG. 8, the first sleeve small-diameter portion 201 of the sleeve 200 includes a circular lever shaft hole 130 </ b> A formed through the fully-closed latch release lever 130 and a circular form formed through the fully-open latch release lever 170. The fully closed latch release lever 130 and the fully open latch release lever 170 are supported by the lever shaft hole 170A (see FIG. 10). One of the fully-closed latch release lever 130 and the fully-open latch release lever 170 corresponds to the “first rotation lever” of the present invention.

  Between the sleeve large diameter portion 203 (sleeve side flange 203F) and the shaft side flange 111F, a clamping groove having the axial length of the first sleeve small diameter portion 201 as a groove width is formed. The axial length of the first sleeve small-diameter portion 201 depends on the design plate thickness of the fully-closed latch release lever 130 (specifically, the periphery of the lever shaft hole 130A) and the fully-open latch release lever 170 (specifically, the lever shaft hole 170A). Peripheral part) and the axial clearance set for smooth rotation of both the rotating levers 130 and 170 are combined, and the fully-closed latch release lever 130 and the fully-open latch release The peripheral portions of the lever shaft holes 130A and 170A in the lever 170 are sandwiched between the shaft side flange 111F and the sleeve side flange 203F from the axial direction. Thereby, the movement of the fully-closed latch release lever 130 and the fully-open latch release lever 170 in the axial direction with respect to the support shaft 111 is restricted.

  Here, the fixing of the support shaft 111 to the base plate 101 and the assembly of the rotation lever and the like to the support shaft 111 are performed as follows. That is, as shown in FIG. 10, the fully open latch release lever 170, the fully closed latch release lever 130, the sleeve 200, the torsion coil spring 19, and the relay rotation lever 120 are inserted in this order from the distal end side of the support shaft 111. At this time, the fully open latch release lever 170 and the fully closed latch release lever 130 are pivotally supported by the first sleeve small diameter portion 201, and the relay rotation lever 120 is pivotally supported by the second sleeve small diameter portion 202. Next, the tip of the support shaft 111 that supports the rotating levers 120, 130, 170, etc. is inserted into the base shaft hole 101 </ b> A from the front side of the base plate 101. At this time, the second sleeve small diameter portion 202 is inserted through the base shaft hole 101A. Finally, the inside input lever 140 is inserted into the tip of the support shaft 111 that penetrates the sleeve 200 and protrudes toward the back side of the base plate 101, and the tip of the support shaft 111 is caulked. As a result, the support shaft 111 that supports the plurality of levers 120, 130, 170 and the like is fixed to the base plate 101. That is, the fixing operation of the inside input lever 140 with respect to the support shaft 111 and the fixing operation of the support shaft 111 with respect to the base plate 101 are performed at a time.

  As described above, according to the present embodiment, the sleeve 200 having the first and second sleeve small diameter portions 201 and 202 at both ends and the sleeve large diameter portion 203 at the intermediate portion is formed on the shaft side of the support shaft 111. It is sandwiched between the flange 111F and the inside input lever 140 and fixed in the axial direction, and the first sleeve small-diameter portion 201 has a shaft that allows a fully-closed latch release lever 130 and a fully-open latch release lever 170 to be pivotable. At the same time, the relay turning lever 120 is pivotally supported by the second sleeve small diameter portion 202 so as to be rotatable. The full-closed latch release lever 130 and the full-open latch release lever 170 are restricted from moving in the axial direction by the shaft-side flange 111F and the sleeve large-diameter portion 203, and the relay rotation lever 120 is the inside input lever 140. And the sleeve large diameter portion 203 are restricted from moving in the axial direction.

  That is, the two lever shaft support portions (first and second sleeve small diameter portions 201 and 202) that pivotally support the rotation lever and restrict the movement in the axial direction are separated in the axial direction of the support shaft 111. The three levers 120, 130, and 170 are shared by and supported by the two lever shaft support portions, so that the axial clearance at each lever shaft support portion is made smaller than the conventional one. be able to. Accordingly, the backlash in the thickness direction of the fully closed latch release lever 130 and the fully open latch release lever 170 in the first sleeve small diameter portion 201 and the backlash in the thickness direction of the relay rotation lever 120 in the second sleeve small diameter portion 202 are obtained. Can be suppressed as compared with the conventional case.

  Further, two sets of four members obtained by adding the base plate 101 to the three rotating levers 120, 130, and 170 (specifically, a combination of the fully-closed latch release lever 130 and the fully-open latch release lever 170). The combination of the relay turning lever 120 and the base plate 101 is inserted into the first sleeve small-diameter portion 201 and the second sleeve small-diameter portion 202. Abnormal noise during operation of 100 can be prevented.

  Further, the fully-closed latch release lever 130 supported by the first sleeve small diameter portion 201 is a lever having the largest turning radius among the four turning levers 120, 130, 140, and 170 supported by the support shaft 111. However, in this embodiment, the fully closed latch release lever is replaced with the shaft side flange 111F and the sleeve side flange 203F. It becomes possible to support stably by sandwiching between.

[Other Embodiments]
The present invention is not limited to the above-described embodiment. For example, the embodiments described below are also included in the technical scope of the present invention, and various other than the following can be made without departing from the scope of the invention. It can be changed and implemented.

  (1) In the above-described embodiment, the relay turning lever 120, the fully-closed latch release lever 130, and the fully-open latch release lever 170 are supported by the common support shaft 111, and the fully closed latch release lever is attached to the first sleeve small diameter portion 201. 130 and the fully open latch release lever 170 are rotatably supported, and the relay rotation lever 120 is rotatably supported by the second sleeve small diameter portion 202. However, the rotation is supported by the common support shaft 111. The number and type of levers, and the number and type of rotating levers supported by the first and second sleeve small diameter portions 201 and 202 may be arbitrarily set.

  (2) In the above embodiment, the inside input lever 140 for transmitting the operating force is also used as the “prevention plate” of the present invention. However, the base plate 101 that does not transmit the operation force is also used as the “prevention plate”. May be. Further, instead of the pivot lever and the base plate, as shown in FIG. 13, a configuration may be adopted in which the tip of the support shaft 111 is passed through and fixed to a dedicated retaining plate 220. The retaining plate 220 may be fixed to the support shaft 111 by caulking the front end portion of the support shaft 111 or the nut 221.

  (3) In the above embodiment, the sleeve side flange 203F is formed at the boundary portion between the sleeve large diameter portion 203 and the first sleeve small diameter portion 201. However, as shown in FIG. A sleeve-side flange 203F may be additionally formed at a boundary portion with the second sleeve small diameter portion 202 in FIG. A configuration in which the sleeve side flange 203F is eliminated from the sleeve 200 (a configuration in which only the first and second sleeve small diameter portions 201 and 202 and the sleeve large diameter portion 203 are provided) may be employed.

( 4 ) In the above embodiment, the shaft side flange 111F is integrally formed with the support shaft 111, but the shaft side flange 111F may be formed as a separate component from the support shaft 111. Specifically, as shown in FIG. 15, an annular groove 111M is formed on the outer peripheral surface of the support shaft 111, and the annular groove 111M is split from the side of the support shaft 111 (for example, a C ring, E A shaft side flange 111F of a ring or the like may be assembled.

( 5 ) Alternatively, as shown in FIG. 16, a stepped portion 111D is formed in the axially intermediate portion with the axially distal end side of the support shaft 111 being a small diameter shaft portion and the proximal end side being a large diameter shaft portion. The ring-shaped shaft-side flange 111F inserted from the distal end side of the support shaft 111 may be sandwiched between the stepped portion 111D and the sleeve 200.

( 6 ) In the above embodiment, the first sleeve small diameter portion 201 has a uniform diameter in the axial direction. However, as shown in FIG. 17, the first sleeve small diameter portion 201 is separated from the sleeve large diameter portion 203. A plurality of small-diameter support portions 201A and 201B are formed so that the diameter gradually decreases, the small-diameter support portion 201A rotatably supports the fully-closed latch release lever 130, and the small-diameter support portion 201B is a fully-open latch release lever. You may comprise so that 170 may be rotatably supported. As a result, it is possible to prevent a mistake that both levers 130 and 170 are erroneously attached in reverse.

( 7 ) Also, as shown in FIG. 18, a plurality of small-diameter support portions 202A and 202B are provided so that the diameter of the second sleeve small-diameter portion 202 gradually decreases as the distance from the sleeve large-diameter portion 203 increases. The support 202A may support the relay turning lever 120, and the small-diameter support 202B may be inserted into the base shaft hole 101A of the base plate 101. Thereby, the mistake of attaching the base plate 101 and the relay rotation lever 120 by mistake reversely can be prevented. In FIG. 17 and FIG. 18, only one of the first and second sleeve small diameter portions 201 and 202 has the above-described stepped structure. However, both the first and second sleeve small diameter portions 201 and 202 May have the stepped structure.

( 8 ) Further, as shown in FIG. 19, the first or second sleeve small-diameter portions 201 and 202 may have a truncated cone shape with a diameter reduced as the distance from the sleeve large-diameter portion 203 increases.

( 9 ) In the above embodiment, the shaft-side flange 111F projecting in a disk shape from the support shaft 111 is exemplified as the “shaft large diameter portion” according to the present invention. The turning lever for transmitting the force may also serve as the “shaft large diameter portion”. Further, the shaft-side flange 111F may not have a disk shape, and may have a rectangular plate shape, for example. Further, the “shaft large diameter portion” is not limited to a shape projecting from the support shaft 111 in a flange shape (saddle shape). For example, the intermediate portion of the support shaft 111 is directed toward the distal end side (the sleeve 200 side). The shape expanded in the shape of a cone may be sufficient.

( 10 ) In the above embodiment, the first and second sleeve small-diameter portions 201 and 202 and the sleeve large-diameter portion 203 are integrally formed with the sleeve 200. However, the sleeve 200 is formed of separate parts for each of these portions. May be. Note that the number of components and the time and effort of assembly can be reduced by integrally forming as in the embodiment.
