  On the other hand, when the operation of moving the sliding door M from the second state in which the sliding door M has completely moved to the door to the other side in the sliding direction (rightward in FIG. 1), the latch 22 resists the urging force of the tension coil spring 41. The sliding door M moves to the other side in the sliding direction (right side in FIG. 1) while moving relative to the sliding door M and the housing 21 in the sliding direction one side (left side in FIG. 1) while the striker 10 is captured. When the predetermined position is reached, the catcher 22b rotates in the R2 direction, the engagement between the latch 22 and the striker 10 is released, and at the same time, the latch 22 is again held at the standby position at the end of the housing 21. Subsequent movement of the sliding door M is released from the urging force of the tension coil spring 41.

  In the assist device 1 according to this embodiment, the height of the striker 10 can be easily adjusted by turning the bolt 15 as an operation of the adjustment mechanism 13. For this reason, it becomes possible to follow the dimensional variation at the time of installation, the temperature after installation, the humidity, the secular change, the vibration, and the dimensional change due to the earthquake. Therefore, the dimensional accuracy of the assist device 1 can be maintained with high accuracy.

  In general, when the height of the sliding door M and the door frame F is adjusted with a door pulley, the assist device may move out of a position where the assist device can operate. However, according to the assist device 1 according to the present embodiment, the allowable height is increased. Even if it comes off, the assist device 1 can be operated by adjusting the position by adjusting the height of the striker 10.

  Further, in this embodiment, the engaging piece 12 and the fixed piece 11 of the striker 10 are configured as separate members, and the swinging shaft 12 c of the engaging piece 12 is fitted into the recess 11 c that opens to one end side of the fixed piece 11. Thus, the engagement piece 12 can swing and can prevent transmission of an impact in the X direction.
