Further, the operation force for releasing the engagement between the striker 55 and the latch mechanism 60 to make the slide door 5 capable of closing operation is transmitted to the latch mechanism 60 via the wire cable 85. A door handle operated to release the fully open holding of the slide door 5 and a remote control device for relaying the operation force are also often provided near the belt line γ of the slide door 5. Therefore, according to the above configuration, the installation operation of the wire cable 85 connected to the latch mechanism 60 can be facilitated, and the assemblability can be improved.

(4) The latch mechanism 60 is provided below the door side center rail 10DC.
That is, the vehicle body side center roller unit 20BC is configured to be connected to the door side center rail 10DC from the lower side. Therefore, according to the above configuration, the latch mechanism 60 can be disposed in the vicinity of the door side center rail 10DC. And thereby, effective utilization of space can be aimed at. In addition, the door side center rail 10DC can be disposed at a higher position closer to the window 5w. And thereby, the slide door 5 can be supported more stably.

  (5) The latch mechanism 60 is supported by a bracket 73 fixed to the inner panel 63 of the slide door 5. The bracket 73 is provided with a stopper portion 88 that restricts the movement of the slide door 5 in the opening direction by abutting on (the guide roller support portion 47 of) the vehicle body side center roller unit 20BC. Thus, the slide door 5 can be prevented from moving in the opening direction beyond the fully open position with a simple configuration.

The above embodiment may be modified as follows.
The slide door 5 may be a power slide door having an opening / closing drive, or may be manually operated.

  In the embodiment described above, the slide door 5 is configured as a rear door of a vehicle, but may be applied to a front door. And it may not be a so-called rear opening type that opens to the vehicle rear side, but may be a front opening type that opens to the vehicle front side.
