DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. The sliding door main body 15 has a concave groove portion 2 for fitting in a lower corner portion. The fitting groove 2 is open at the end face and the lower face in the running direction. The upper part of the fitting groove 2 in the vertical direction is a wide groove 3 wider than the lower end.

The traveling body 5 is provided with rollers 4 on the underside of the traveling body 1.
Is rotatably mounted. The running body 1 is shaped so that it can be fitted exactly from the side opening of the recess 2 for fitting, so that the upper part of the running body 1 in the vertical direction is wider than the lower end. Wide part 6
It has become. A transverse screw insertion hole 7 is formed in the traveling body 1 so as to penetrate the traveling body 1 at an end face in the traveling direction. The screw insertion hole 7 is formed in the wide portion 6.

As shown in FIG. 4, the traveling body 1 comprises an L-shaped member 16 made of synthetic resin and an L-shaped member 16 and a metal roller supporting case 17 to which the roller 4 is rotatably mounted. is there. The L-shaped member 16 is vertically integrated with the upper end of the vertical piece 18.
A horizontal piece 19 wider than the piece 18 is continuously extended, and the wide piece 19 is a wide portion 6. An engagement groove 20 cut out in a C-shape is provided in the horizontal piece portion 19, and an engagement portion 21 provided in the upper end of the roller support case 17 and projecting in a C-shape is engaged with the engagement groove 20. And the vertical piece 18
Is provided with an engagement protrusion 22, which is engaged with an engagement recess 23 provided in the support case 17. A rotation plate 25 is rotatably supported by a shaft 24 in the support case 17.
The roller 4 is rotatably supported by the rotating plate 25. The rotating plate 25 is provided with a vertically long hole 26, and a shaft 28 inserted into a horizontally long hole 27 provided in the support case 17 is inserted through the vertically long hole 26 of the rotating plate 25. A screw hole 30 is provided in the shaft body 28 in a direction orthogonal to the shaft center.
9 is rotatably screwed. The screw 29 is attached to the support case 17 so as to be rotatable but not movable in the axial direction. The screw 29 is rotatable by a rotary operation part 31 inserted through the vertical piece 18. Therefore, when the rotation operation part 31 is rotated, the shaft 28 moves in the horizontally long hole 27, whereby the side edge of the vertically long hole 26 is pushed by the shaft 28, and the rotating plate 25 is rotated. Support case 17
The length of the protrusion from the lower end can be adjusted.
In this way, the support portion of the roller 4 including the protrusion adjusting mechanism of the roller 4 is made of metal, so that the support is assured, and the portion exposed on the side end surface of the sliding door body 15 is made of synthetic resin. Because the vertical piece 18 of the L-shaped member 16 is used, the metal is not exposed to the outside and the appearance is improved.

The mounting of the traveling body 5 having the above configuration is performed as follows. First, the traveling body 1 is fitted into the fitting groove 2 from the side. In this case, the wide portion 6 is fitted into the wide groove portion 3, and the traveling body 1 is fitted so as not to move in the vertical direction. In this state, the running body 1 is attached to the lower corner of the sliding door main body 15 by inserting the screw 8 into the lateral screw insertion hole 7 from the side and fixing it to the sliding door main body 15. As described above, the fitting of the wide portion 6 to the wide groove portion 3 can prevent the traveling body 1 from moving in the vertical direction. As a result, only by inserting and fixing the screw 8 from the side, The traveling body 1 can be firmly attached to the sliding door body 15.

As described above, the traveling body 5 is mounted, and the upper guide 12 projects upward from the upper surface of the sliding door body 15 to form a sliding door. The sliding door having such a configuration is disposed between the upper rail 13 and the lower rail 14 as shown in FIG. 3, the roller 4 of the traveling body 5 is slidably fitted on the lower rail 14, and the upper guide 12 is freely slidable on the upper rail 13. It fits in. Here, the load of the sliding door main body 15 is supported by the traveling body 5, but since the wide portion 6 is fitted into the wide groove portion 3, the sliding door main body 15 and the traveling body main body 1 are Are integrated so as not to move in the vertical direction, and the load on the sliding door main body 15 can be stably supported by the traveling body main body 1.

[0012]

According to the present invention, as described above, a fitting groove is provided in the lower corner portion of the sliding door body at the end face and the lower surface in the running direction of the sliding door body, and the fitting recess is provided. forming a wide wide width groove grooved width than the lower end portion in the vertical direction of the top of the groove, the traveling body provided rotating freely around constitute a running body, the wide width portion to the upper portion of the traveling body The wide body is fitted into the wide groove while the running body is fitted in the fitting groove, and a lateral screw insertion hole is formed in the end face of the running body in the running direction. Since the screw inserted into the door is fixed to the sliding door body, it can be prevented from moving up and down by fitting the wide part into the wide groove. The traveling body can be attached to the sliding door body at And input fixing work well only insert securing work from fitting in the same direction to fitting groove of the running body, the mounting operation of the traveling body is intended to simplify. Also, an L-shaped synthetic resin having a vertical piece and a horizontal piece is used.
The traveling body with the L-shaped member and metal roller support case
And the vertical and horizontal pieces of the L-shaped member and the support case.
