- the locked position of the slider 14-2 is maintained. If the second slider 14-2 is out of the locked position due to a malfunction, the inlet portion 18e of the trigger pin receiving groove 18d of the trigger catcher 18 will not be able to receive the second trigger pin 8-2.

- the retracting device 4 moves in the closing direction together with the sliding door 1.
- the trigger catcher 18 contacts the first trigger pin 8-1. Then, the trigger catcher 18 rotates to capture the first trigger pin 8-1 and the first slider 14-1 can slide with respect to the base 12. Since the tension coil spring 15 is interposed between the first slider 14-1 and the base 12, a tensile force for sliding the first slider 14-1 acts. Since the trigger catcher 18 captures the first trigger pin 8-1 fixed to the guide rail 2, the base 12 moves in the closing direction without the trigger catcher 18 moving.
- the damper base 22 Since the sliding door 1 starts to move in the closing direction as the base 12 moves in the closing direction, the force to close the sliding door 1 is reduced. Since the damper base 22 is integrated with the base 12 by the damper lock 28 for the first slider, the damper base 22 also moves in the closing direction with respect to the first slider 14-1. As a result, the distance between the damper base 22 and the first slider 14-1 is reduced, and the rod 24 b is inserted into the damper main body 24 a of the linear damper 24. For this reason, the linear damper 24 generates a braking force. Since the linear damper 24 operates and generates a large braking force during an initial operation in which the spring force of the tension coil spring 15 is large, the operation of the sliding door 1 can be made smooth.
- a damper main body 25 a of the rotary damper 25 is provided at the end of the damper base 22 in the opening direction. Since the slide rack 25b that meshes with the pinion of the damper main body 25a is attached to the second slider 14-2, the distance between the second slider 14-2 and the damper base 22 is reduced, so that the rotary damper 25 rotates. To do. A braking force is generated by the rotation of the rotary damper 25. Even after the operation of the linear damper 24 is completed, the operation is switched to the rotary damper 25, and the rotary damper 25 generates a braking force until the sliding door 1 is fully closed. For this reason, it becomes possible to prevent the occurrence of collision and noise when fully closed. In the latter half of the pull-in operation, the pulling force of the pulling coil spring 15 is also small, so that the braking force generated by the rotary damper 25 can be small. Eventually, as shown in FIG. 13C, the sliding door 1 is completely closed.
- the linear damper 24 can be operated first, and then the rotary damper 25 can be operated. . If the damper lock 28 for the first slider is not provided on the damper base 22, either the linear damper 24 or the rotary damper 25 is activated first unless the braking force of the linear damper 24 and the braking force of the rotary damper 25 are increased or decreased. Is unstable. By providing the damper lock 28 for the first slider on the damper base 22, such instability can be eliminated.

- the trigger catcher 18 rotates. As shown in (2-1) and (2-2) of FIG. 14, as the trigger catcher 18 rotates, the locking piece 18b of the trigger catcher 18 is locked to the locking slit 14a-2 of the first slider 14-1. And it comes out of the locking groove 12b-2 of the base 12. As shown in (3-1) and (3-2) of FIG. 14, the malfunction return cam 20 rotates with the rotation of the trigger catcher 18. Since the opening angle of the fan-shaped opening 20a of the malfunction return cam 20 is larger than that of the locking piece 18b, the rotation angle of the malfunction return cam 20 is smaller than that of the trigger catcher 18.
- the damper lock 28 enters the recess 14g of the first slider 14-1.
- the slider-side hook 28b of the damper lock 28 engages with the recess 14g of the first slider 14-1, so that the first slider 14-1 and the damper base 22 are integrated. .
- the pinion of the damper main body 25a of the rotary damper 25 rotates while meshing with the slide rack 25b locked to the base 12 via the second slider 14-2. Since the rotary damper 25 is set so that no braking force is generated in the rotational direction when the sliding door 1 is opened, the load when the sliding door 1 starts to open is an elastic force generated by extending the tension coil spring 15. Only.

- the trigger catcher 18 contacts the second trigger pin 8-2. Then, the trigger catcher 18 rotates to capture the second trigger pin 8-2, and the second slider 14-2 can slide with respect to the base 12. Since the tension coil spring 16 is interposed between the second slider 14-2 and the base 12, a tensile force for sliding the second slider 14-2 acts. Since the trigger catcher 18 captures the second trigger pin 8-2 fixed to the guide rail 2, the base 12 moves in the opening direction without the trigger catcher 18 moving. As the base 12 moves in the opening direction, the sliding door 1 starts moving in the opening direction, so that the force to open the sliding door 1 is reduced.
- the damper lock 28 for the first slider of the damper base 22 is free with respect to the base 12, and the damper base 22 is slidable with respect to the base 12. That is, the damper lock 28 for the first slider does not engage the base 12 and the damper base 22 with respect to the movement in the opening direction of the base 12. It is possible to operate the linear damper 24 or the rotary damper 25 first. However, in this embodiment, since the braking force of the rotary damper 25 is set to be smaller than the braking force of the linear damper 24, the rotary damper 25 first operates. That is, the damper base 22 moves in the opening direction together with the base 12, and the distance between the damper base 22 and the second slider 14-2 is reduced.
- the base 12 and the damper base 22 move in the opening direction with respect to the second slider 14-2, so that the damper main body 25a of the rotary damper 25 fixed to the damper base 22 rotates.
