The panel 15 is inserted into a through hole 15a of a panel 15 fixed to the panel 15, and is fastened to a nut (not shown) positioned across the panel 15. Thereby, the shaft 11 is supported by the panel 15 so as to be able to move forward and backward. A seal member 16 is disposed between the guide member 14 around the shaft 11a and the flange portion 11b, and this seal member 16 prevents water, dust, gasoline vapor, etc. from entering between the guide member 14 and the shaft 11. It prevents you from doing so. Retainer 1
2 is fixed to the support portion 10b on the same axis as the shaft 11. This retainer 12 is formed with a locking portion 12a, and the spring 13 is formed with a locking portion 11d and a locking portion 12a.
a and is disposed between the shaft 11 and the retainer 12, and constantly urges the shaft 11 in the projecting direction (leftward in FIG. 1). Since the locking portion 12a of the retainer 12 and the locking portion 11d of the shaft 11 are located opposite to each other, the locking portion 12a functions as a stopper that restricts the retreat of the shaft 11 in the retraction direction (rightward direction in FIG. 1). do. The foot portion 11c is in contact with a wall portion 10c formed on the base 10, and the shaft 11 is prevented from rotating. Further, as shown in FIGS. 3 and 4, the shaft 11 is formed with a cavity 17 that is open at the rear end of the shaft 11 and extends in the axial direction. A stop wall 17a is formed.

As shown in FIGS. 1, 2 and 5, the first linking means 6 is composed of an outer tube 18 and an inner wire 19 slidably inserted into the outer tube 18.

In this way, the locking point between the inner wire 19 and the locking wall 17a is located on the same axis as the shaft 11 and the spring 12. As a result, the shaft 11 of the inner wire 19
Since the direction in which the force is applied and the direction in which the spring 13 is biased can be the same, the shaft 11 does not twist against the guide member 14 when the shaft 11 moves back and forth, and the movement is smooth with little operating resistance. operation can be ensured. Furthermore, one retainer 1 has both the function of locking the outer tube 18 and the function of a stopper for restricting the retreat of the shaft 11 in the retracting direction.
2, the number of parts can be reduced.

As shown in FIGS. 1 and 2, the second drive mechanism is a handle 3 disposed in the interior or trunk room.
2, and a wire 33, which is a second linking means, is connected to this handle 32.

As shown in FIGS. 6 and 7, the first drive mechanism 7 includes a case 21, a motor 22, and a gear mechanism 23.
and a drum 24.

The case 21 is composed of a housing 25 and a cover 26 that overlaps the housing 25 in the thickness direction (vertical direction in FIG. 2).
and an internal space 27 in which the drum 24 is placed. The motor 22 has a holding part 2 formed in the housing 25.
5a, 25b, and 25c, and includes a rotating shaft 25a whose tip end is rotatably supported by a bearing portion 25d formed in the housing 25. This rotating shaft 22a
A worm gear 28 is fixedly attached to the worm gear 28 so as to rotate together with the worm gear 28. A gear shaft 29 is integrally formed in the housing 25. A worm wheel gear 31 is rotatably supported by the gear shaft 29, and the worm gear 31 meshes with the worm gear 28. The teeth of the worm gear 28 and the worm wheel gear 31 are set to have a large advance angle, and both are rotated from the worm gear 28 to the worm wheel gear 31 and from the worm wheel gear 31 to the worm gear 28. is now possible. The tip of the gear shaft 29 is the cover 2
It is supported by a recess 30 formed in 6. Thereby, during operation, the load applied from the worm wheel gear 31 to the gear shaft 29 can be shared and received by both the housing 25 and the cover 26. A drum 24 is rotatably supported around a shaft portion 31a of the worm wheel gear 31. As shown in FIGS. 8 to 12, the outer peripheral surface of the drum 24 is formed by a separator 34 in the thickness direction (
The separator 34 is divided into two parts in the vertical direction in FIG. A locking portion 37 is provided on the wire winding portion 35 side. The other end of the inner wire 19 has a through hole 2 formed in the housing 25.
5f and is wired in the internal space 27, and is locked to the locking part 37 by a locking piece 38 that is wound around the wire winding part 35 and fixed to the tip. The other end of the outer tube 18 is press-fitted and fixed into a fitting portion 25e formed in the housing 25. Further, a locking portion 39 is provided on the wire winding portion 36 side. The other end of the wire 33 is inserted into through holes 46 and 47 formed as described later, and routed within the internal space 27, and is wound around the wire winding portion 36 and fixed to the tip thereof. It is locked to the locking part 39 by the piece 40. A contact piece 41 is formed integrally with the locking part 37 on the drum 24, and the worm wheel gear 31
As shown in FIGS. 12 to 14, a transmission portion 42 is formed which comes into contact with the locking portion 37 only when the worm wheel gear 31 rotates in one direction. When the worm wheel gear 31 and the drum 24 are assembled, a gap 43 larger than the diameter of the inner wire 19 is provided between the transmission section 42 and the separator 34 in order to prevent the inner wire 19 from being caught between them. Further, washers 44 are provided between the housing 25 and the worm wheel gear 31 and between the cover 26 and the worm wheel gear 31 and the drum 24, respectively. This prevents an increase in operating resistance between the housing 25 and the worm wheel gear 31 and between the cover 26 and the worm wheel gear 31 and the drum 24 due to the reaction force in the thrust direction against the load applied to the cover 26 . Furthermore, the drum 24 of the cover 26
A protrusion 45 is formed around the washer 44 to protrude toward the drum 24, and the presence of this protrusion 45 prevents the wire 33 from being caught between the drum 24 and the cover 26.

As shown in FIGS. 7 and 15, a pair of walls 48 and 49 are provided upright in the housing 25, and recesses 50 and 51 are formed at the ends of the walls 48 and 49, respectively. The cover 26 is formed with convex portions 52 and 53 that fit into the concave portions 50 and 51, and through holes 46 and 47 through which the wire 33 is inserted are formed between the concave portions 50 and 51 and the convex portions 52 and 53, respectively. is forming.

As shown in FIGS. 6, 7 and 15,
A passage 54 is formed between the walls 48 and 49, and a lead wire 55 connected to the motor 22 is routed through the passage 54. This lead wire 55 is disposed outside through a through hole 25g formed in the housing 25, and is connected to a connector 57 (see FIGS. 1 and 2) fixed to the cover bag 26 via a bracket 56. Further, the case 26 is formed with a pair of walls 58 and 59 that extend into the passage 54, and these walls 58 and 59 hold the lead wire 55 at the bottom of the passage 54 and prevent it from coming into contact with the wire 33. ing.

Incidentally, the case 21 is held on the panel 15 via a bracket 60 fixed to the housing 25.

Next, the operation of the lid lock device 4 having the above structure will be explained.

1 and 2 show a closed state of the opening 2 with the lid body 3 in the closed position, the shaft 11 protrudes under the urging force of the spring 13, and the shaft portion 11a of the shaft 11 is in the closed position of the lid body 3. It engages with the engagement recess 3a to hold the lid body 3 in the closed position. In this state, when the motor 22 is operated, the worm wheel gear 31 rotates in one direction via the rotating shaft 22a and the worm gear 28. As the worm wheel gear 31 rotates in one direction, the contact piece 41 and the transmission section 42 come into contact with each other, and the drum 24 also rotates in one direction together with the worm wheel gear 31. Due to this rotation of the drum 24, the inner wire 19 is wound around the wire winding portion 35 and pulled, and as a result, the engagement piece 19a and the locking wall 17a come into contact with each other, and the shaft 11 resists the urging force of the spring 13. and regress in the direction of immersion. At this time, since the direction in which the inner wire 19 is applied to the shaft 11 and the direction in which the spring 13 is biased are in the same direction, smooth operation with little operating resistance can be ensured. 22 can be made smaller. As a result, the engagement between the shaft portion 11a and the engagement recess 3a is released, and the holding of the lid body 3 in the closed position is released. After this, the motor 22
When the operation of the shaft 11 is stopped, the spring 13
The inner wire 19 returns to its initial state under the urging force of the shaft 11 and the urging force of the spring 13, and sets the advance angle of the teeth of the worm gear 28 and the worm wheel gear 31. The drum 24 also rotates in the other direction and returns to its initial position. Further, when changing the lid body 3 from the open position to the closed position, the operator only has to rotate the lid body 3 and push it in so that the engagement recess 3a and the shaft portion 11a are engaged. At this time, the shaft portion 11a once retreats in the retracting direction in order to overcome the engagement recess 3a, but since the engagement piece 19a of the inner wire 19 only slides within the cavity 17 of the shaft 11, the shaft 11 The inner wire 19 is not compressed due to regression. This improves the durability of the inner wire 19. Furthermore, lid body 3
When the handle 32 is operated while the drum 24 is held in the closed position, the wire 33 is pulled and the drum 24 rotates in one direction while winding the wire 33 in the wire winding section 36.

At this time, the rotation of the drum 24 is not transmitted to the worm wheel gear 31 due to the relative positional relationship between the contact piece 41 and the transmission section 42. As a result, the operation of the handle 32 does not drag the worm wheel gear 31, the worm gear 28, and the motor 22, and the operation becomes very light, thereby improving the operation feeling. Due to this rotation of the drum 24 in one direction, the inner wire 19 is wound around the wire winding section 35, and as a result, the shaft 11 retreats in the retracting direction against the biasing force of the spring 13, and the lid 3 is released from being held in the closed state.

As mentioned above, the operation of the locking mechanism 5 is effected by the winding of the first linking means 6 by the operation of the first drive mechanism. Thereby, the lock mechanism 5 and the first drive mechanism 7 can be disposed separately, and can be easily mounted even in a vehicle with limited mounting space. Further, the forward and backward movement of the shaft 11 by operating the handle 32 is performed by rotating the drum 24 via the wire 33 and finally winding up the inner wire 19 in the same way as the forward and backward movement of the shaft 11 by the operation of the motor 22. .

Accordingly, the direction in which force is applied to the shaft 11 due to the operation of the handle 22 can be made to be the same direction as the biasing direction of the spring 13, as well as the direction in which the force is applied to the shaft 11 due to the operation of the motor 22. As a result, handle 2
Even with the operation 2, no distortion occurs in the forward and backward movement of the shaft 11, and smooth forward and backward movement of the shaft 11 can be ensured. Furthermore, since the locking mechanism 5 is operated by winding up the first linking means 6, the operation is quiet with little noise, and the locking mechanism 5 and the first
Variations in the arrangement position of the drive mechanism 7 can also be absorbed, and reliable operation of the lock mechanism 5 can be ensured.
