In order to achieve the above object, an upper roller mounting structure for a slide door according to the present invention as set forth in claim 1 has a bracket fixed to an inner surface of the slide door, and the base is slid on the bracket. In an upper roller mounting structure for a slide door in which a position is freely adjustable in a direction orthogonal to a door, and an upper roller is rotatably pivotally attached to a tip of the base, a reference hole is provided in the base while the bracket is provided with the reference hole. It is characterized in that a reference pin fitted into the reference hole is provided so that a fixed position can be adjusted in the same direction as the position adjustment direction of the base.

In order to achieve the above object, the upper roller mounting structure for a sliding door according to the present invention is defined by the following:
In the structure described in claim 1, a guide having a small diameter is provided at a tip of the reference pin so as to guide the fitting of the base with the reference hole.

[0007]

The operation and effect of the upper roller mounting structure for the slide door according to the first aspect of the present invention are as follows. Temporarily tighten the base of the upper roller to the slide door side bracket in the building jig, and tighten the reference pin that fits into the reference hole of the base to the bracket. The relative position of the upper roller and the slide door is defined in the building jig, and the reference pin fitted into the reference hole of the base is also fixed at the position specified by the jig. Accordingly, even when the base of the upper roller is temporarily tightened, the upper roller can be positioned at the position adjusted by the building jig by fitting the reference pin and the reference hole of the base.

According to the slide door upper roller positioning structure of the second aspect, the base of the upper roller is formed by providing the tip of the reference pin with a small-diameter guide for guiding the fitting with the reference hole of the base. Even when the slide door is mounted on the body in the temporarily tightened state, the upper roller can be positioned at the position adjusted by the building jig simply by fully tightening the base.
