In the fully closed state, the outer surface 9 b of the front guide rail 9 is held between the front rotating roller 25 and the rear rotating roller 27.

  Below, the effect by embodiment of this invention is demonstrated.

(1) In the sliding door support structure according to the present embodiment, the sliding door opening 7 is formed on the side surface of the vehicle body, and the sliding door 5 is slid on the upper edge 7a and the lower edge 7b of the opening 7. A front guide rail 9 that supports the front guide rail 9 is disposed, and a front end 9a of the front guide rail 9 is formed as a curved portion that gently curves inward in the vehicle width direction toward the front of the vehicle. An engagement member that engages with the front guide rail 9 is provided at the front end of the front rotation roller. The engagement member is supported by the inner side of the front guide rail 9 and slides on the front rotation roller (front engagement member) 25. A rear rotation roller (rear engagement member) 27 disposed on the rear side of the rotation roller 25 and on the outer side in the vehicle width direction of the front guide rail 9.

  According to the slide door support structure of the present embodiment, when the slide door 5 is moved to the front side and closed, the front rotation roller 25 is directed from the outer side in the vehicle width direction to the inner side with respect to the front guide rail 9. When the slide door 5 is closed gradually, the outer side surface 9b of the front guide rail 9 is held between the inner side and the outer side in the vehicle width direction by the front rotating roller 25 and the rear rotating roller 27. The sliding force when closing the slide door 5 can be reduced to reduce the operating force.

  Further, in the vehicle manufacturing process, it is necessary to paint the slide door 5 separately from the vehicle body. Therefore, it is necessary to remove the slide door 5 from the guide rails 9 and 33 before the painting process. Here, in this embodiment, since the front side rotation roller 25 and the rear side rotation roller 27 are arranged at a predetermined interval in the front-rear direction, the slide door 5 is easily removed from the guide rails 9 and 33. be able to.

(2) Since the engaging member is composed of the front rotating roller (rotating roller) 25 and the rear rotating roller (rotating roller) 27 that are rotatably supported by the roller portion, the sliding door 5 is closed. The sliding resistance can be reduced to reduce the operating force, and the durability can be improved.

  Note that the present invention is not limited to the above-described embodiment, and various changes and modifications can be made based on the technical idea of the present invention.

  For example, in the above-described embodiment, the example in which the rear rotation roller 27 is provided as the rear engagement member constituting the front end side support portion 29 has been described. Instead of the rear rotation roller 27, a non-rotatable rubber member is provided. It is also possible to adopt. For this rubber member, for example, it is preferable to fasten a block-like rubber formed in a rectangular parallelepiped shape to a mounting plate via a long bolt or the like. As described above, in the process of closing the slide door 5, the rear engagement member gradually approaches the front guide rail 9 from the outer side in the vehicle width direction, and finally comes out of the front guide rail 9. It contacts the side surface 9b. That is, since the rear engagement member hardly slides on the front guide rail 9, a non-rotatable rubber member other than the rotation roller described in the above embodiment may be used. In the case of this rubber member, since it is elastically pressed against the outer side surface 9b of the front guide rail 9 as the slide door 5 is closed, noise and rattling when the slide door 5 is closed are suppressed. And the manufacturing cost can be reduced.
