It has an area that covers up to one side edge.

Next, functions and effects of the first embodiment will be described.
First, the operation will be described with reference to FIGS.
Since the slide door support device according to the first embodiment is configured as described above, coating is performed according to the following procedure.

That is, in the vehicle painting process, as shown in FIG. 6, the slide door 1 is constructed by assembling only the front upper roller unit 3 and the lower roller unit 4 to the upper guide rail 22 and the lower guide rail 23, respectively. The painting is performed by holding the rear side of the slide door 1 around the shaft 43 in an open state like a hinge door.
At that time, since the movement of opening the slide door 1 like a hinge door is also restricted by the swing restriction stopper 7, the swing restriction stopper 7 removes the fixing by the bolt 71 to the roller side bracket mounting portion 61 of the door side bracket 6. Therefore, the swing regulation is released.

In this way, when painting is performed with the rear side of the slide door 1 opened like a hinge door around the support shaft 43, the upper surface of the roller side bracket mounting portion 61 of the door side bracket 6 as shown in FIG. Of these, the portion D1 covered with the swing restriction stopper 7 is not coated.
However, when the sliding door 1 opened like a hinge door is returned to the vehicle body assembled state after the painting process is finished, as shown in FIG. 7, the portion D1 where the coating is not applied is covered with the swing regulating stopper 7 and cannot be seen. become.

  As described in detail above, in the slide door support device of the first embodiment, the swing restriction stopper 7 is such that the pivot tip of the swing restriction stopper 7 is a support shaft (shaft support portion) of the swing restriction stopper 7. It has the structure which has the width which covers the inside of circular arc R1 drawn on the roller side bracket attaching part 61 of the door side bracket 6 toward the side which cancels | releases the rotation range regulation of the roller side bracket 41 centering on 43. Then, when the sliding door 1 is returned to the assembled state after completion of the painting process, the portion (unpainted portion) D1 where the coating of the roller side bracket mounting portion 61 in the door side bracket 6 has not been applied is covered with the swing regulating stopper 7. It becomes a state.

Therefore, it is possible to prevent the unpainted portion from being exposed without increasing the number of parts.
In addition, since the contact area between the roller side bracket mounting portion 61 and the swing restriction stopper 7 in the door side bracket 6 is increased, the rigidity of the connection portion of the roller side bracket 41 with respect to the door side bracket 6 can be increased.

  Further, the restricting means for restricting the rotation range of the door side bracket 6 is a protrusion 7c that is formed to protrude from the tip of the swing restricting stopper 7 and contacts the side wall 41c of the roller side bracket 41. Swing regulation can be performed using the existing side wall 41c provided in the bracket 41 as a stopper surface.

  Moreover, the structure can be simplified because the shaft support portion of the swing regulating stopper 7 is supported coaxially with the support shaft 43 that is the shaft support portion of the roller side bracket 41 and the door side bracket 6.
