Each end of the cable connected to the guide roller member is allowed to swing with respect to the guide roller member so as to follow the swing when the guide roller member moves along the guide rail.
Japanese Patent Publication No. 5-61432 JP 2008-128322 A (page 3, FIG. 5)

  By the way, the vehicle door opening / closing device of Patent Document 1 is fixed with a cylindrical locking piece (P) oriented in a direction perpendicular to the axis of the cable (C) as pointed out as the prior art of Patent Document 2. In addition, a cable hook formed in a bifurcated shape with a pair of leg pieces (F) is formed on the bracket of the guide roller member. Then, both ends of the locking piece are fitted into holes (fitting holes) formed in both leg pieces, and the cable is pulled out from between the pair of leg pieces, and the end of the cable is engaged with the guide roller member (bracket). It has stopped.

  In addition, when the locking piece is fitted into the fitting holes of the pair of leg pieces, a slit (S) through which the cable passes is provided in one leg piece so that the cable does not interfere with the leg piece. The slit is provided at a position deviated from the normal cable extending direction so that the locking piece (cable) is not detached from the leg piece at the normal time. Therefore, when attaching the locking piece to the leg piece, it is necessary to match the direction of the cable with the direction of the slit. However, it is common that the cable is already provided with a tension suitable for preventing slack during normal operation, and the cable hook that attaches the locking piece to the leg piece against this tension is generally used. The connecting work was not easy.

  On the other hand, in the vehicle door opening / closing device itself of Patent Document 2, a pair of cable hooks are fixed to a bracket of a guide roller member, and cylindrical bushes are mounted in advance on locking pieces of both ends of the cable. Then, the end of the cable is engaged with the guide roller member (bracket) by pushing the bush attached to each locking piece inward of the substantially U-shaped portion of the cable hook against the urging force of the leaf spring. It has stopped. However, when connecting a cable end to a cable hook that does not move with respect to the guide roller member, it is necessary to largely shift the cable in a direction different from the original extending direction. May be subject to minute constraints.

  An object of the present invention is to provide a vehicle door opening and closing device that can more easily connect the ends of cables and can further reduce restrictions on the degree of freedom of arrangement.

In order to solve the above problem, the invention according to claim 1 is fixed to either the vehicle body side or the vehicle door side that opens and closes the door opening formed in the vehicle body, A drive member having a drum that is rotationally driven by a power source and a cable wound around the drum; and both ends of the cable connected to either the vehicle body side or the vehicle door side by the drive member In the vehicle door opening and closing device that opens and closes the vehicle door by selectively winding and unwinding, the vehicle body side and the vehicle door around a rotating shaft extending in a direction different from the extending direction of the cable Each hook portion having a pair of hook portions rotatably connected to either one of the sides and extending from the rotation shaft in different directions extending from the cable. A cable hook formed by branching by the slit is fixed to the terminal of the cable, and a pair of engaging pieces to be hooked on the hook portion and the cable is threaded into the slit and is fixed to the vehicle body A roller that rolls on a guide rail extending in the opening / closing direction of the vehicle door is rotatably connected to the vehicle door, and the roller is guided by the guide rail to guide opening / closing of the vehicle door. A guide roller member, and the cable hook is connected so that the pair of hook portions individually rotate with respect to the guide roller member, and the pair of hook portions has an opening side with respect to the guide roller member. in the rotational direction is opposite the respective support wall portion of the guide roller members, kite includes a biasing means, each for biasing said support wall portion the pair of hook portions The the gist.

  According to this configuration, since the hook portion (cable hook) is rotatable about a rotation axis extending in a direction different from the extending direction of the cable, the cable body side of each terminal of the cable or The connection to the vehicle door side is achieved by pressing the hook portion with the locking piece in the extending direction of the cable while passing the cable through the slit, so that the hook portion is rotated and the locking is performed. A piece is caught and completed. In this way, each end of the cable basically has the cable hook (vehicle body side) simply pressing the hook portion in the extending direction of the cable, that is, the tension direction of the cable. Or the vehicle door side), the connection workability of the cable to the cable hook can be facilitated. Further, when the hook piece is hooked on the hook portion, the hook portion (cable hook) is rotated, so that the displacement necessary for the lock piece can be reduced correspondingly, and the cable is The amount of shifting in a direction different from the extending direction can be made little or no. Thereby, the restriction | limiting of the arrangement | positioning freedom degree of the said cable can be reduced more.

  According to this configuration, the pair of hook portions individually rotate with respect to the guide roller member, so that the moving direction of the guide roller member is inclined with respect to the extending direction (that is, the tension direction) of the cable. However, the amount of rotation of the locking piece relative to the hook portion can be reduced by rotating the hook portion so that the extending direction of the hook portion substantially coincides with the extending direction of the cable. . Thereby, the bending stress added to the connection part with the said locking piece of the said cable can be reduced, and the durability of the said cable can be improved by extension. Further, when tension is applied to one of the terminals of the cable connected to the pair of hook parts, the tension of the other terminal is released, but the hook part connected to the terminal is As the distance from the support wall is reduced by the biasing means being biased toward the support wall, the end (locking piece) of the cable is released by the swing of the hook. Can be suppressed.

According to a second aspect of the present invention, there is provided a drive source, a drum that is rotationally driven by the drive source, and a drum that is fixed to either the vehicle body side or the vehicle door side that opens and closes a door opening formed in the vehicle body, A driving member having a cable wound around a drum, and selectively winding and unwinding both ends of the cable connected to either the vehicle body side or the vehicle door side by the driving member; In the vehicle door opening and closing device that opens and closes the vehicle door, the vehicle door and the vehicle door can be pivoted about a pivot shaft extending in a direction different from the extending direction of the cable. And a pair of hook portions extending in different directions from which the cable extends from the rotating shaft, and each hook portion is branched by a slit. A cable hook, a pair of locking pieces fixed to the end of the cable, passed through the slit and hooked to the hook portion, and fixed to the vehicle body and extended in the opening / closing direction of the vehicle door. A guide roller member having a roller for rolling an existing guide rail and rotatably connected to the vehicle door, the roller being guided by the guide rail to guide opening and closing of the vehicle door, The cable hook is rotatably connected to the guide roller member so that the pair of hook portions rotate integrally around the rotation shaft, and the opening side of the pair of hook portions is the guide roller. The gist is that each of the guide roller members is opposed to the support wall portion in the rotation direction with respect to the member.
According to this configuration, since the hook portion (cable hook) is rotatable about a rotation axis extending in a direction different from the extending direction of the cable, the cable body side of each terminal of the cable or The connection to the vehicle door side is achieved by pressing the hook portion with the locking piece in the extending direction of the cable while passing the cable through the slit, so that the hook portion is rotated and the locking is performed. A piece is caught and completed. In this way, each end of the cable basically has the cable hook (vehicle body side) simply pressing the hook portion in the extending direction of the cable, that is, the tension direction of the cable. Or the vehicle door side), the connection workability of the cable to the cable hook can be facilitated. Further, when the hook piece is hooked on the hook portion, the hook portion (cable hook) is rotated, so that the displacement necessary for the lock piece can be reduced correspondingly, and the cable is The amount of shifting in a direction different from the extending direction can be made little or no. Thereby, the restriction | limiting of the arrangement | positioning freedom degree of the said cable can be reduced more.
The invention according to claim 3, wherein the vehicle door opening and closing device according to claim 2, extending tension side of the terminal is the extending direction of one of the hook part connected to the cable tension force acts When the cable hook is rotated so as to coincide with the direction, one of the hook portions to which the tension side terminal to which the tension acts is connected is rotated so that the opening side is away from the support wall portion. The other hook part connected to the terminal on the relaxation side where the tension is released is rotated so that the opening side approaches the support wall part.

According to this configuration, the pair of hook portions rotate integrally with the guide roller member. Therefore, for example, when the moving direction of the guide roller member is inclined with respect to the extending direction of the cable (that is, the tension direction), one of the hook portions connected to the end (locking piece) on the tension side where the tension acts is applied. The cable hooks (both hook portions) rotate so that the extending direction coincides with the extending direction of the cable. At this time, the other hook portion connected to the end (locking piece) on the relaxation side from which the tension is released is rotated so that the opening side approaches the support wall portion. It is possible to prevent the end (locking piece) of the cable from coming off as the distance becomes smaller.
According to a fourth aspect of the present invention, in the vehicle door opening and closing device according to any one of the first to third aspects, the cable hook is disposed directly below or directly above the roller and is rotated around the guide roller member. The gist is that they are movably connected.
According to this configuration, the cable hook is disposed immediately below (above) the roller (and the guide rail), so that the end of the cable connected to the hook portion via the locking piece also It is arranged directly below (above) the roller. Therefore, the amount of shift of the movement trajectory of the cable with respect to the roller can be reduced as a whole, and the restriction on the degree of freedom of arrangement of the cable can be further reduced.

  According to the present invention, it is possible to provide a vehicle door opening and closing device that can more easily connect cable terminals and that can further reduce restrictions on the degree of freedom of arrangement.

In the drawing, the upper side and the lower side correspond to the vehicle width direction outer side (vehicle outer side) and the inner side (vehicle inner side), respectively, and the left side and the right side correspond to the vehicle front side and the rear side, respectively.

  As shown in FIG. 8, the center rail 13 is formed of, for example, a metal plate, and has a curved portion 13a at a middle portion in the longitudinal direction and extends in the vehicle front-rear direction (that is, the opening / closing direction of the slide door 20). Exist. The center rail 13 forms a bent portion 13b that inclines inward in the vehicle width direction on the front end side of the curved portion 13a, and a linear portion 13c that extends rearward on the rear end side of the curved portion 13a. A front pulley 17 is rotatably supported by the vehicle body 10 so as to face the front end of the center rail 13 (bending portion 13b) and face the rear end of the center rail 13 (straight portion 13c). The rear pulley 18 is rotatably supported.

  A driving member 30 is fixed to the vehicle body 10 so as not to protrude at least on the vehicle exterior side of the center rail 13. The drive member 30 includes a drive motor 31 as a drive source, a drum 32 that is rotationally driven by the drive motor 31, and a front cable 33 and a rear cable 34 that are wound around the drum 32. The front cable 33 passes through the outer tube 35 routed between the drum 32 and the front pulley 17 and extends to the front and is exposed to the outside. The front cable 33 is hung on the front pulley 17 and turned to the rear. A terminal 33 a (see FIG. 1) extending rearward is connected to the guide roller unit 16. On the other hand, the rear cable 34 passes through the outer tube 36 routed between the drum 32 and the rear pulley 18 and extends to the rear side to be exposed to the outside, and is hung on the rear pulley 18 and turned to the front side. Further, a terminal 34 a (see FIG. 1) extending further to the front side is connected to the guide roller unit 16.

While moving to the front side, the slide door 20 connected to the guide roller unit 16 is integrally moved to the front side (closing operation). On the other hand, when the drum 32 is rotationally driven in the other direction by the drive motor 31 and the rear cable 34 is wound up and the front cable 33 is fed out, the guide roller unit 16 connected to the terminal 34 a is moved along the center rail 13. While moving to the rear side, the slide door 20 connected to the guide roller unit 16 is integrally moved to the rear side (opening operation).

  In particular, the slide door 20 is pushed to the outside of the vehicle immediately after the guide roller unit 16 is opened from the fully closed position, for example, by being guided by the center rail 13 on the front end side (curved portion 13b) of the curved portion 13a. Or it is pulled inside the vehicle just before reaching the fully closed position. This is because the sliding door 20 is allowed to slide backward when the sliding door 20 is opened, and is arranged so as to be flush with the side surface of the vehicle body 10 when fully closed. Although a detailed description is omitted, the front end portions of the upper rail 11 and the lower rail 12 are also gently curved toward the vehicle interior side for the same reason.

  Next, how the guide roller unit 16 and the terminal 33a of the front cable 33 and the terminal 34a of the rear cable 34 are connected will be described. 1 and 2 are a perspective view and a front view showing the guide roller unit 16, and FIGS. 3 and 4 are cross-sectional views taken along lines AA and BB in FIG. As shown in FIG. 4, the center rail 13 is formed in a substantially C-shaped constant cross-sectional shape that opens to the vehicle outer side (sliding door 20 side), and extends to the vehicle outer side. The first roller guide 13d is formed at the same time, and the tip of the upper wall portion extending outward from the vehicle is folded downward to form the second roller guide 13e.

  As shown in FIGS. 1 to 4, the guide roller unit 16 includes a base plate 21 made of, for example, a metal plate, a load roller 22, and a pair of vertical rollers 23 and 24. The base plate 21 is attached to an appropriate bracket (not shown) provided at the lower part of the slide door 20 so as to be pivotally connected around a pivot axis O1 (see FIG. 1) extending in the vehicle height direction.

Have. The support wall portion 21c is bent in a substantially “<” shape in cross section, and an upper portion thereof rises in a substantially vertical direction to form a vertical wall portion 21d, and the vertical wall portion 21d is centered in the vehicle front-rear direction. A first support piece 21e protruding upward from the portion is formed, and a pair of second support pieces 21f bent to the vehicle inner side on both sides in the vehicle front-rear direction sandwiching the first support piece 21e are formed. The load roller 22 is coupled to the first support piece 21e so as to be rotatable about a rotation shaft extending in the direction of entry into the center rail 13. The vertical rollers 23 and 24 are coupled to both the second support pieces 21f so as to be rotatable about a rotation axis extending in the vertical direction.

  As shown in FIG. 4, the guide roller unit 16 has the load roller 22 supported by the first roller guide 13d in a state where the vertical rollers 23 and 24 are rotatably mounted on the second roller guide 13e. Yes. Therefore, the guide roller unit 16 rolls the load roller 22 along the first roller guide 13d while rolling the vertical rollers 23 and 24 along the second roller guide 13e of the center rail 13. Move in the longitudinal direction of the vehicle. At this time, the sliding door 20 that moves integrally with the guide roller unit 16 opens and closes the door opening 10a as described above.

  The base plate 21 has a quadrangular through hole 25 penetrating the center portion in the vehicle width direction. The base plate 21 is provided with a cable terminal connecting member 40 that enters from the vehicle outer side through the through hole 25 to the vehicle inner side.

  More specifically, the cable terminal connecting member 40 includes a mounting bracket 41 made of a metal plate that is joined to the outer surface of the support wall 21c that is bent into a substantially "<" shape. The mounting bracket 41 has an extending wall portion 41a extending through the through hole 25 to the vehicle inner side, and a vertical wall portion 41b rising in a substantially vertical direction from the tip of the extending wall portion 41a in the through hole 25.

The support bracket 42 includes a coupling piece 42a joined to the inner side surface of the vertical wall portion 41b, and a pair of support pieces 42b and 42c extending from the upper end and the lower end of the coupling piece 42a to the vehicle interior side. Shaped in a letter shape.

  A cable hook 44 is rotatably connected to the support bracket 42 around a support pin 43 that penetrates both support pieces 42b and 42c in the vehicle height direction. The cable hook 44 is disposed immediately below the load roller 22 or the like. Of course, the cable hook 44 may be arranged directly above the load roller 22 or the like. Here, “directly (immediately above)” does not necessarily indicate strictly directly (directly above), but has a certain range. As shown in FIG. 4, the distance W from the support wall portion 21 c to the vehicle inner surface of the guide rail 13 is included in “directly below (directly above)”.

  The cable hook 44 includes a hook portion 45 made of a metal plate extending from the support pin 43 (rotating shaft) in the extending direction of the rear cable 34. The hook portion 45 has a pair of hook-shaped hook pieces 45a and 45b that are spaced apart from each other in the vehicle height direction and are in sliding contact with the lower surface of the support piece 42b and the upper surface of the support piece 42c, respectively, and face the coupling piece 42a. Then, it has a regulating piece 45c (see FIG. 3) that rises in a substantially vertical direction and integrates both hook pieces 45a and 45b. The hook portion 45 is pivotally supported by the support pin 43 at the base end side with respect to the regulating piece 45c, and the hook-shaped tip portion is formed by separating both hook pieces 45a and 45b in the vehicle height direction. It is branched by a slit 45d (see FIGS. 1 and 2).

  The cable hook 44 includes a hook portion 46 made of a metal plate that extends from the support pin 43 in the extending direction of the front cable 33. The hook portion 46 has a pair of hook-shaped hook pieces 46a and 46b that are spaced apart from each other in the vehicle height direction and are in sliding contact with the lower surface of the hook piece 45a and the upper surface of the hook piece 45b, respectively, and is opposed to the coupling piece 42a. Then, it has a regulating piece 46c (see FIG. 3) that rises in a substantially vertical direction and integrates both hook pieces 46a and 46b. The hook portion 46 is pivotally supported by the support pin 43 on the base end side of the restricting piece 46c, and the hook-shaped tip portion is formed by separating the hook pieces 46a and 46b in the vehicle height direction. It is branched by a slit 46d (see FIGS. 1 and 2).

  In other words, the pair of hook portions 45 and 46 extending from the support pin 43 in different directions (in opposite directions) are connected to the support bracket 42 (guide roller unit 16) so as to be individually rotated.

  As shown in FIG. 3, the hook portions 45, 46 have a bowl-shaped opening side facing the support wall portion 21 c in the rotation direction around the support pin 43, and the regulation pieces 45 c, 46 c are supported by the support bracket 42 ( When the rotation is restricted by coming into contact with the coupling piece 42a), the bowl-shaped opening side is set so as to come closest to the support wall portion 21c. Further, a torsion coil spring 47 as an urging means is mounted around the support pin 43 between the hook pieces 46a and 46b, and one end and the other end of the coil spring 47 are respectively restricted pieces. 45c and 46c are in elastic contact. The coil spring 47 urges the hook portions 45 and 46 toward the support wall portion 21c to hold the hook portions 45 and 46 at an initial position where the restricting pieces 45c and 46c abut against the support bracket 42. Is.

  On the other hand, a substantially cylindrical locking piece 48 having a center line extending in the vehicle height direction is fixed to the terminal 33a of the front cable 33. The locking piece 48 is hooked on the hook portion 46 in such a manner that both ends in the axial direction are locked to the hook pieces 46a and 46b, and the terminal 33a (front cable 33) connected to the locking piece 48 is a slit 46d. And the interference with the hook portion 46 is avoided. Similarly, a substantially cylindrical locking piece 49 having a center line extending in the vehicle height direction is fixed to the end 34a of the rear cable 34. The locking piece 49 is hooked on the hook portion 45 in such a manner that both end portions in the axial direction are locked to the hook pieces 45a and 45b, and the terminal 34a (rear cable 34) connected to the locking piece 49 is a slit. The interference with the hook portion 45 is avoided by passing through 45d.

  That is, the locking pieces 48 and 49 can swing with respect to the hook members 44 and 45 when the terminals 33a and 34a run idle in the slits 45d and 46d. The front cable 33 and the rear cable 34 are allowed to swing the locking pieces 48 and 49 with respect to the hook portions 46 and 45, so that an excessive bending load is suppressed. The front cable 33 and the rear cable 34 are basically connected to the lower side of the center rail 13 by being connected to a cable hook 44 (hook portions 46 and 45) arranged directly below the load roller 22 and the like. It has been routed. The front pulley 17 and the rear pulley 18 are also arranged below the center rail 13 in the vehicle height direction.

  Here, as shown by a solid line in FIG. 5, when the terminal 34a of the rear cable 34 is wound to open the slide door 20, the tension-side terminal 34a (the locking piece 49) on which the tension acts is applied. The hook portion 45 rotates so that the extending direction of the connected hook portions 45 coincides with the extending direction of the rear cable 34. This amount of rotation increases remarkably when the guide roller unit 16 passes near the curved portion 13a of the center rail 13. At this time, the hook part 46 connected to the terminal 33a on the relaxation side where the tension is released is urged by the coil spring 47, and the opening side is held at the initial position closest to the support wall part 21c. Therefore, for example, it is possible to prevent the terminal 33a (the locking piece 48) from being detached from the hook portion 46 due to an unintended external force.

  On the other hand, as shown by a two-dot chain line in FIG. 5, when the terminal 33a of the front cable 33 is wound so as to close the slide door 20, the tension-side terminal 33a (the locking piece 48) on which tension is applied. The hook portion 46 is rotated so that the extending direction of the hook portion 46 connected to the front cable 33 coincides with the extending direction of the front cable 33. This amount of rotation increases remarkably when the guide roller unit 16 passes near the curved portion 13a of the center rail 13. At this time, the hook part 45 connected to the terminal 34a on the relaxation side where the tension is released is urged by the coil spring 47, and the opening side is held at the initial position closest to the support wall part 21c. Therefore, for example, the terminal 34a (the locking piece 49) can be prevented from being detached from the hook portion 45 due to an unintended external force.

  Further, as shown in FIG. 6, the front cable 33 is connected to the cable hook 44 (cable terminal connecting member 40) of the terminal 33a by passing the front cable 33 through the slit 46d with the hook piece 46 ( When the hook pieces 46a, 46b) are pressed in the generally extending direction of the front cable 33, the hook portion 46 rotates in the counterclockwise direction shown in the figure so as to open the opening side against the urging force of the coil spring 47. At the same time, the latching piece 48 is hooked by the return rotation accompanying the approach of the latching piece 48 to the opening side. Similarly, the connection of the terminal 34a of the rear cable 34 to the cable terminal connecting member 40 (sliding door 20 side) is performed by the hook portion 45 (hook piece 45a) by the locking piece 49 while passing the rear cable 34 through the slit 45d. , 45b) is pushed in the extending direction of the rear cable 34, the hook portion 45 is rotated in the clockwise direction shown in the figure so as to open the opening side against the urging force of the coil spring 47, and It completes by hooking the locking piece 49 by the return rotation accompanying the approach of the locking piece 49 to the opening side. As described above, the terminals 33a and 34a of the cables 33 and 34 basically do not bend, but the locking pieces 48 and 49 generally extend in the extending direction of the cables 33 and 34, that is, the tension of the cables 33 and 34. It is connected to the cable hook 44 (slide door 20 side) simply by pressing the hook portions 46 and 45 in the direction.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the hook portions 46 and 45 (cable hooks 44) are rotatable around the support pins 43 whose axis extends in a direction different from the extending direction of the cables 33 and 34. , 34 are connected to the slide door 20 side (guide roller unit 16) of the terminals 33a, 34a by connecting the hook portions 46, 45 with the locking pieces 48, 49 while passing the cables 33, 34 through the slits 46d, 45d. When the cables 33 and 34 are pressed in the generally extending direction, the hook portions 46 and 45 are rotated and the locking pieces 48 and 49 are hooked to complete. As described above, the end portions 33a and 34a of the cables 33 and 34 basically have hook portions 46 in the extending direction of the cables 33 and 34, that is, in the tension direction of the cables 33 and 34 by the locking pieces 48 and 49. , 45 can be connected to the cable hook 44 (sliding door 20 side) simply by pressing, the connection workability of the cables 33, 34 to the cable hook 44 can be facilitated. Moreover, when hooking pieces 48 and 49 are hooked on the hook portions 46 and 45, the hook portions 46 and 45 (cable hooks 44) rotate to reduce the displacement required for the locking pieces 48 and 49 correspondingly. Therefore, the amount of shifting the cables 33 and 34 in a direction different from the original extending direction can be made little or no. Thereby, the restriction | limiting of the arrangement | positioning freedom degree of the cables 33 and 34 can be reduced more.

  (2) In the present embodiment, the cable hook 44 is disposed directly below the load roller 22 (and the center rail 13), and is thus connected to the hook portions 46 and 45 via the locking pieces 48 and 49. Terminals 33a and 34a of the cables 33 and 34 are also arranged immediately below the load roller 22 and the like. Therefore, the displacement amount of the movement trajectory of the cables 33 and 34 with respect to the load roller 22 and the like can be reduced as a whole, and the restriction on the degree of freedom of arrangement of the cables 33 and 34 can be further reduced.

  In particular, since the range of the cable hook 44 (cable terminal connecting member 40) in the vehicle front-rear direction is within the range of the guide roller unit 16 in the direction, the guide roller unit 16 along the center rail 13 in the vehicle front-rear direction. The moving range of the direction is not restricted by the cable hook 44. Accordingly, for example, the front pulley 17 does not need to be shifted in the extending direction of the center rail 13 (curved portion 13b) so that the range of movement of the guide roller unit 16 in the vehicle longitudinal direction is not restricted by the cable hook. The amount of protrusion of 17 to the vehicle inner side can be suppressed. Or in order to suppress the protrusion amount to the vehicle inner side of the front pulley 17, it is not necessary to reduce the moving range of the guide roller unit 16 in the vehicle front-rear direction, that is, the opening amount of the slide door 20.

  (3) In the present embodiment, the pair of hook portions 46 and 45 are individually rotated with respect to the guide roller unit 16 (support bracket 42), so that the moving direction of the guide roller unit 16 is that of the cables 33 and 34. Even if the hook portions 46 and 45 are inclined with respect to the extending direction (ie, the tension direction), the hook portions 46 and 45 are rotated so that the extending direction of the hook portions 46 and 45 substantially coincides with the extending direction of the cables 33 and 34. The amount of rotation of the locking pieces 48 and 49 relative to the hook portions 46 and 45 can be reduced. Thereby, the bending stress added to the connection part with the locking pieces 48 and 49 of the cables 33 and 34 can be reduced, and the durability of the cables 33 and 34 can be improved. Further, when tension is applied to one of the terminals 33a and 34a of the cables 33 and 34 connected to the pair of hook portions 46 and 45, the tension of the other terminal 33a and 34a is released. The hook portions 46 and 45 to which the terminals 33a and 34a are connected are held at the corresponding initial positions by the coil spring 47, so that the distance from the support wall portion 21c is reduced, for example, the hook portions 46 and 45 It can suppress that terminal 33a, 34a (locking piece 48, 49) of the cables 33 and 34 remove | deviates by rocking | fluctuation.

As shown in FIGS. 9 to 12, the through hole 25 is omitted from the base plate 21 (support wall portion 21 c) of the present embodiment, and a cable terminal connecting member 50 is installed inside the base plate 21. ing.

  Specifically, as shown in FIG. 12, the cable terminal connecting member 50 includes a support bracket 51 made of a metal plate joined to the inner surface of the support wall portion 21 c. The support bracket 51 includes a coupling piece 51a joined to the inner side surface of the support wall 21c and a support piece 51b extending from the upper end of the coupling piece 51a to the vehicle interior side, and is formed in a substantially L-shaped cross section. Yes.

  A cylindrical member 52 with a flange penetrating the support piece 51b in the vehicle height direction is attached to the support bracket 51, and a cable hook 54 is rotatable around a support pin 53 inserted through the cylindrical member 52. It is connected. The cable hook 54 is disposed immediately below the load roller 22 or the like. Of course, the cable hook 54 may be arranged directly above the load roller 22 or the like. As shown in FIG. 12, the distance W from the support wall portion 21 c to the vehicle inner surface of the guide rail 13 is included in “directly below (directly above)”.

  The cable hook 54 is formed by folding a metal plate in the vehicle height direction, and is in sliding contact with the support piece 51b on which the cylindrical member 52 is mounted in that direction. The cable hook 54 is integrally provided with a pair of hook portions 55 and 56 extending from the support pin 53 (rotating shaft) in the extending direction of the rear cable 34 and the extending direction of the front cable 33, respectively.

  The hook portion 55 has a pair of hook-shaped hook pieces 55a and 55b spaced apart from each other in the vehicle height direction, and both the hook pieces 55a and 55b are integrated on the side away from the support wall portion 21c (the vehicle interior side). The connecting piece 55c is provided. The hook-shaped tip end portion of the hook portion 55 is branched by a slit 55d (see FIG. 9) formed by separating both hook pieces 55a and 55b in the vehicle height direction.

  Similarly, the hook portion 56 has a pair of hook-shaped hook pieces 56a and 56b spaced apart in the vehicle height direction, and both the hook pieces 56a and 56b are separated from the support wall portion 21c (the vehicle interior side). Has a connecting piece 56c. The hook-shaped front end portion of the hook portion 56 is branched by a slit 56d (see FIG. 9) formed by separating both hook pieces 56a and 56b in the vehicle height direction.

  Each hook portion 55, 56 has a hook-shaped opening side facing the support wall portion 21c in the rotational direction around the support pin 53, and any one of the hook portions 55, 56 contacts the support wall portion 21c. When the rotation of the hook portions 55 and 56 is restricted, the hook-shaped opening side of the hook portions 55 and 56 is set to be closest to the support wall portion 21c. Further, the cable hook 54 is folded over via connecting pieces 55c and 56c arranged on the vehicle inner side of the hook portions 55 and 56, respectively.

  As in the first embodiment, the locking pieces 48 fixed to the terminal 33a are hooked on the hook portions 56 in such a manner that both end portions in the axial direction are locked to the hook pieces 56a and 56b, respectively. The terminal 33a (front cable 33) connected to the stop piece 48 is passed through the slit 56d to avoid interference with the hook portion 56. Further, the locking piece 49 fixed to the terminal 34 a is hooked on the hook portion 55 in such a manner that both ends in the axial direction are locked to the hook pieces 55 a and 55 b, and the terminal 34 a connected to the locking piece 49 is connected. The (rear cable 34) is passed through the slit 55d to avoid interference with the hook portion 55. Accordingly, the front cable 33 and the rear cable 34 are allowed to swing the locking pieces 48 and 49 with respect to the hook portions 56 and 55, thereby suppressing an excessive bending load.

  Here, as shown in FIG. 11, when the front cable 33 and the rear cable 34 connected to the cable hook 54 are arranged on a straight line, the distance between the hook portions 56 and 55 and the support wall portion 21c is separated. Are set equal to each other.

  Then, as shown in FIG. 13, when the terminal 34a of the rear cable 34 is wound to open the slide door 20, the tension-side terminal 34a (locking piece 49) on which the tension acts is connected. The cable hook 54 (hook portion 55) rotates so that the extending direction of the hook portion 55 coincides with the extending direction of the rear cable 34. When the guide roller unit 16 passes through the vicinity of the curved portion 13a of the center rail 13, the rotation amount becomes maximum when the hook portion 56 abuts on the support wall portion 21c and is restricted from rotating. Therefore, the hook portion 56 connected to the terminal 33a on the relaxation side where the tension is released rotates so that the hook-shaped opening side is closest to the support wall portion 21c, so that the separation distance from the support wall portion 21c is increased. It can suppress that terminal 33a (locking piece 48) remove | deviates from the hook part 56 by the part which becomes narrow.

  On the other hand, as shown in FIG. 14, when the terminal 33a of the front cable 33 is wound to close the slide door 20, the hook to which the tension-side terminal 33a (locking piece 48) to which tension acts is connected. The cable hook 54 (hook portion 56) rotates so that the extending direction of the portion 56 coincides with the extending direction of the front cable 33. When the guide roller unit 16 passes through the vicinity of the curved portion 13a of the center rail 13, the rotation amount becomes maximum when the hook portion 55 abuts against the support wall portion 21c and is restricted from rotating. Accordingly, the hook portion 55 connected to the loose end 34a from which the tension is released rotates so that the hook-shaped opening side is closest to the support wall portion 21c, so that the separation distance from the support wall portion 21c is increased. It is possible to suppress the terminal 34 a (the locking piece 49) from being detached from the hook portion 55 by the narrowing.

The rotational position of the cable hook 54 (hook portions 55, 56) is basically held by the tension of the front cable 33 or the rear cable 34.
The connection of the terminal 33a of the front cable 33 and the terminal 34a of the rear cable 34 to the cable hook 54 (cable terminal connecting member 50) is performed in the first embodiment except that both hook portions 55 and 56 rotate together. It is the same as the form.

As described above in detail, according to the present embodiment, the following effects can be obtained in addition to the effects (1) to (2) in the first embodiment.
