2. Description of the Related Art A sliding door that slides along the side of a body has upper, lower, and center rollers provided on the body side, which are provided at upper and lower portions of a front end portion and an intermediate portion in a vertical direction of a rear end portion. The upper guide rail, the lower guide rail, and the center guide rail are slidably engaged with each other and can be opened and closed (Japanese Utility Model Laid-Open No. 3-98121, Japanese Utility Model Laid-Open No. 5-17293). In such a sliding door, an upper roller, a lower roller, and a center roller are mounted on the sliding door so as to be position-adjustable for mounting adjustment. This is performed in a fixture. That is, each roller is fastened and fixed to the slide door in a state where the relative position between the slide door and each roller is defined by the jig. In addition, this mounting jig can adjust the relative position of each roller with respect to the slide door so that the installation of the slide door is within the standard according to the body accuracy having the variation in each production lot. I have.

When the slide door is mounted on the body, the upper roller is engaged with the upper guide rail that opens downward with the center roller engaged with the center guide rail, and then the lower roller is connected to the lower guide rail. In general, the rear guide rail is engaged with the lower guide rail through a catch spring mounting notch at the rear end. However, depending on the shape of the body, the upper roller may not be engaged with the upper guide rail as described above with the upper roller fixed to the slide door. In this case, the upper roller is temporarily tightened, the lower roller is engaged with the lower guide rail, and then the upper roller is fully tightened to engage the upper roller with the upper guide rail.

However, in the method of mounting the slide door on the body with the upper roller temporarily tightened as described above, the positioning of the upper roller is difficult, and the variation in mounting the slide door is increased. there were. The present invention has been made to solve the above problems, and even when a slide door is mounted on a body in a state where the upper roller is temporarily tightened, if the upper roller is fully tightened, the upper roller is automatically positioned and fixed at a position where the upper roller is installed and adjusted. It is an object of the present invention to provide an upper roller mounting structure for a sliding door.

[0005]

According to the first aspect of the present invention, there is provided an upper roller mounting structure for a slide door, wherein a bracket is fixed to an inner surface of the slide door, and the base is attached to the bracket. In a slide door upper roller mounting structure in which a position is freely fixed in a direction orthogonal to a slide door and an upper roller is rotatably pivotally attached to a tip of the base, a reference hole is provided in the base, and the bracket is provided in the base. to, provided to project an adjustable reference pin fixed position relative to the bracket in the position adjustment in the same direction as the direction of the base by fitting the reference hole in the reference pin, said base relative to said bracket Then together so as to be positioned

According to a second aspect of the present invention, there is provided an upper roller mounting structure for a slide door according to the present invention.
In the configuration described in claim 1, a small-diameter guide that guides the fitting of the base with the reference hole is protruded from a tip of the reference pin.

[0007]

In the mounting jig, the base of the upper roller is temporarily fastened to the slide door side bracket, and the reference pin is fastened and fixed to the bracket with the reference pin fitted in the reference hole of the base. Since the relative position between the upper roller and the slide door, that is, the relative position between the bracket and the base, is defined in the mounting jig, the reference pin is also fixed to the bracket at the position specified by the mounting jig. This allows the reference hole to move along the reference pin's projection direction so that the upper roller does not interfere with the upper guide rail when the slide door is mounted on the body.
Even if the positional relationship between the bracket and the base is shifted, if the reference pin and the reference hole of the base are fitted after the slide door is mounted on the body, the base is defined in the mounting jig with respect to the bracket. That is, the upper roller is positioned at the adjusted position in the mounting jig with respect to the slide door.

According to the slide door upper roller positioning structure of the present invention, a small-diameter guide for guiding the fitting of the base with the reference hole of the base is projected from the tip of the reference pin, so that the base of the upper roller is formed. 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 mounting jig simply by fully tightening the base.

As shown in FIG. 1, the sliding door 2 that slides along the side surface of the body 1 has three portions, that is, an upper portion and a lower portion of a front end portion and an intermediate portion in a vertical direction of a rear end portion, which are respectively disposed on the body 1 side. It is engaged with the upper guide rail 3, the lower guide rail 4, and the center guide rail 5, and is slidably supported.

[0010] As shown in FIGS.
A bracket 11 for an upper roller is fixed to an inner surface of the upper part by a bolt (not shown). Bracket 11
The fixing surface 13 is bent at right angles to the end of the fixing surface 12. Further, an engaging piece 14 is formed to be bent at a right angle at the center of the other end of the fixing surface 12 so as to face the fixing surface 13. In the approximate center of the fixing surface 12, an adjusting slot 15 whose longitudinal direction is orthogonal to the fixing surface 13 is drilled, and the adjusting direction is aligned on both sides of the adjusting slot 15. Holes 16, 16 are formed in parallel.

A reference pin 17 is inserted through the adjustment slot 15 of the bracket 11 and is fixed at a position set by a mounting jig (not shown). The reference pin 17 has a reference hole 26 to be described later at a protruding end protruding from the upper surface of the bracket 11.
A small-diameter portion 18 serving as a guide at the time of fitting into is formed. Further, a tapered portion 20 is formed between the small diameter portion 18 and the shaft portion 19. A screw portion 21 is formed at the lower end of the shaft portion 19, and a flange portion 22 is formed between the screw portion 21 and the shaft portion 19. The reference pin 17 is fixed by tightening a nut 23 to a screw portion 21 protruding from the adjustment slot 15 to the lower surface of the bracket 11.

A base 24 fixed on the fixing surface 12 of the bracket 11 has a substantially trapezoidal planar shape with a reduced width at one end, and a bulge 25 toward the one end at the center of the upper surface.
Are formed. The bulging portion 25 has the reference pin 1
A reference hole 26 through which the reference numeral 7 is inserted, and an engagement long hole 27 through which the engagement piece 14 is engaged are formed. The longitudinal direction of the engaging long hole 27 is aligned with the longitudinal direction of each of the adjusting long holes 15, 16, 16. The position adjustment can be performed on the bracket 11. On both sides of the bulging portion 25, retainer nuts 28, 28 are fixed so as to correspond to the adjustment slots 16, 16, respectively.
