振動を防止することができる。As shown in FIG. 3, a large number of cilia 16c are formed on both sides of the base 16a of the covering material 16. And the door suspension part 4 of this embodiment is formed by extrusion molding of aluminum, and the door roller 12 is made of iron. According to the above configuration, since the covering material 16 prevents the door wheel 12 from contacting the traveling rail 6 when the door body 7 opens and closes in the retracting direction, the durability of the traveling rail 6 and the door roller 12 is dramatically improved. I do. Therefore,
Since the number of replacements of the door suspension unit 4 or the door roller 12 is reduced as compared with the related art, maintenance costs can be significantly reduced. Further, when the structure of the present embodiment is adopted for an automatic door, even if the driving vibration of the door opening / closing drive unit incorporated in the wall is transmitted to the traveling rail 6, the covering material 16 is not covered by the door
Since the vibration to the side is insulated, the vibration of the door body 8 when the door is opened and closed can be prevented.

The rolling surfaces 12a, smaller set than the radius of curvature R 2 of the rolling surface 12a of the radius of curvature R 1 of the cover portion 16b (R 1 <R 2)
As a result, the contact area between them is reduced, and the frictional resistance between the door wheel 12 and the covering portion 16b is reduced, so that the door body 8 can be opened and closed smoothly. In addition, the coating material 16
Is made of a wear-resistant material such as polyamide resin or urethane resin. Therefore, even if the door wheel 12 rolls, it is not easily worn and deteriorated. Can be removed.

Since the area is reduced and the frictional resistance between the door wheel and the covering material is reduced, the door body can be opened and closed smoothly. According to the third aspect of the present invention, since the covering material is formed of a wear-resistant elastic material such as a urethane resin or a polyamide resin, the covering material does not easily wear and deteriorate even when the door wheel rolls. In addition, when the present invention is applied to an automatic door, even if the driving vibration of the door opening / closing drive unit incorporated in the wall is transmitted to the traveling rail, the covering material insulates the vibration toward the door car side, so that the door at the time of opening and closing the door is provided. Vibration of the main body can be prevented.
