【Example】

 As shown in FIG. 1, the door roller (3) has a wheel (4), a mounting bracket (5) for rotatably supporting the wheel (4), and a mounting bracket (5) for fixing to the door plate (1). It is composed of screws (6) and (7).

The attachment fitting (5) has an opening (51) in the center of the strip (50) through which the wheels (4) are exposed, and a semicircle is formed on both side edges of the central portion of the strip (50). The support walls (52) (52) are provided, and the wheel (4) is rotatably fitted to the support shaft (41) inserted between the support walls (52) (52).

Both ends of each support wall (52) (52) extend low to the end of the strip to form reinforcing ribs (55) (55).

At both ends of the strip plate (50), screw insertion parts (53) (54) are opened to penetrate the front and back of the strip plate. In the embodiment, both screw insertion parts (53) (54) are stripped. It is open to the end face of the plate (50).

Among the two screws (6) and (7), one is a normal dish screw (7) and one is a special screw (6) which is a feature of the present invention. The special screw (6) has a cylindrical head portion (61), and a peripheral groove (62) is formed on the outer peripheral surface of the head portion (61) on the screw shaft side.

The diameter of the thin shaft portion (63) formed by the circumferential groove (62) is slightly smaller than the width of the screw insertion portions (53) (54). The width of the circumferential groove (62) is such that the opening edges of the screw insertion portions (53) (54) fit in a state with a slight margin.

Since the screw (6) with a peripheral groove is usually used by screwing the screw (6) before the deadline, not in the closed state, so that the screw shaft is not easily loosened, the screw shaft is the other dish screw. It is longer than that of (7).

However, of the two door rollers (3) (3a) attached to the lower surface of the door plate (1), one door roller (3a) is fixed to the door plate (1) with two plate screws.

To install the other door roller (3), one of the screw insertion parts (53) (54) at both ends of the attachment fitting (5) has a head (61 ) Is fitted and the opening edge of the screw insertion part (54) is fitted into the circumferential groove (62), the wheel (4) is attached to the wheel accommodating hole at the lower end of the door plate (1). Insert it into (12) and screw the grooved screw (6) into the door plate (1).

If the door plate (1) is attached to the sliding door attachment opening and there is a gap between the door plate (1) in the closed position and the vertical frame (21), the door plate (1) is once removed and the installation height is increased. Slightly loosen the countersunk screw (7) of the door roller (3) whose position can be adjusted, and depending on the position and width of the gap between the door plate (1) and the vertical frame (21), screw with a peripheral groove (6) ) Tighten or loosen.

When the screw (6) is tightened, the mounting bracket (5) approaches the lower surface of the door plate (1) around the other plate screw (7), and the wheel (from the wheel accommodating hole (12) ( The protrusion of 4) becomes small. When the screw with peripheral groove (6) is turned in the loosening direction, the protrusion of the wheel (4) becomes large contrary to the above. After adjusting the protrusion amount of the wheel (4), tighten the countersunk screw (7).

Again, the door plate (1) is attached to the sliding door attachment opening. If the vertical frame (21) or the sill (2) is tilted and a new gap is created between the door plate (1) and the vertical frame (21), the height position of the wheel (4) is adjusted by the above procedure. Readjust.

As described above, the height of the wheel (4) can be adjusted by turning the screw (6) with the peripheral groove (62), and as in the conventional case, the door wheel mounting surface of the door plate (1) can be adjusted. It is possible to save the trouble of inserting a spacer between the mounting bracket (5) or cutting the door roller mounting surface.

It should be noted that both of the two door rollers (3) and (3a) to which the door plate (1) is attached are provided with peripheral grooved screws (so that the height of the vehicle wheel (4) shown in FIGS. 1 and 2 can be adjusted.
