It is attached to the lower guide rail 4. Therefore, since the position variation of the striker 13 with respect to the buffer member 20 can be reduced without picking up the size variation between the lower guide rail 4 and the vehicle body at the time of assembly, the size of the groove 6a of the latch portion 6 with respect to the diameter size of the striker 13 can be reduced. There is no need to make it too large, and when holding the slide door, it is possible to improve the sense of quality by suppressing the occurrence of flapping and gacha sounds.

  Further, in the present embodiment, the first bolt 8a for attaching the bracket 10 to the lower guide rail 4 is inserted into the insertion hole 19 provided in one longitudinal end portion (rear end portion 4R) of the lower guide rail 4, and the head portion 8d is provided. The buffer member 20 is inserted so as to be located inside the lower guide rail 4, and the buffer member 20 contacts the head 8 d of the first bolt 8 a, so that the buffer member 20 is in the longitudinal direction of the lower guide rail 4. Since the protrusion 24 that restricts movement to one end side (rear end portion 4R side) is provided, the buffer member 20 can be prevented from falling off from the rear end portion 4R of the lower guide rail 4, The buffer member 20 can be positioned with a simple configuration in which the protrusion 24 of the buffer member 20 contacts the head 8 of the first bolt 8a.

  Furthermore, in this embodiment, among the mounting holes 11 of the bracket 10, the mounting holes 11a through which the first bolts 8a are inserted are used as reference holes, and the other mounting holes 11b are displaced from the positions of the second bolts 8b. Since the bracket 10 is attached to the lower guide rail 4 as an allowable escape hole, the positional displacement of the bracket 10 and the buffer member 20 with respect to the lower guide rail 4 is suppressed, and variations in the mounting position of the stat bolt 8 are not picked up. In addition, the bracket 10 can be attached to the lower guide rail 4. With such a configuration, since the displacement of the striker 13 and the buffer member 20 with respect to the fully open position of the slide door (the fully open position of the latch portion 6 and the guide roller portion 9) is reduced, the groove of the latch portion 6 with respect to the radial dimension of the striker 13 is reduced. The 6a dimension can be set even smaller, and the quality can be further improved.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, in the above-described embodiment, the stopper structure for the slide door according to the present invention is applied to the lower guide rail.
