2. Description of the Related Art Conventionally, in steel furniture such as cabinets and office desks, a drawer opening / closing device using a rail and a resin slide has been widely used. Generally, the opening and closing device of the drawer is disclosed, for example, in Japanese Utility Model Publication No. 57-46841,
As disclosed in Japanese Patent Publication No. -15461, etc., a rail receiver is provided on each of the inner surface of the drawer housing such as a cabinet and the outer surface of the drawer, and the drawer side is provided on a rail receiver near a drawer opening of the housing. A guide roller or a fixed slider for supporting the lower surface of the rail is provided, and a movable slider made of resin that slides on a rail receiver on the housing side is attached to the rear end of the drawer side rail.

[0003]

The drawer-side rail disclosed in Japanese Utility Model Publication No. 57-46841 is fixed to a drawer side wall formed in a flat plate shape. A rail body having a U-shaped cross section having a pair of horizontal pieces facing each other and a vertical piece connecting one side of both horizontal pieces, and upward and downward from the other sides of the upper and lower horizontal pieces of the rail body. Each has a mounting piece portion extending therefrom, and is formed by bending a metal plate such as a steel plate. However, since it has a total of five pieces, the bending process is troublesome and the processing cost is high. There was a disadvantage of becoming. The moving slider made of resin attached to the rear end of the rail is fitted into openings formed in the upper and lower horizontal pieces so as to protrude upward and downward from the horizontal pieces of the rail body having a U-shaped cross section, respectively. It is configured to slide in contact with a pair of upper and lower horizontal pieces of the rail receiver, but since this moving slide is incorporated inside the vertical piece, using this moving slide There was a drawback that the drawer could not be swung right and left.

On the other hand, a rail having a U-shaped cross section disclosed in Japanese Utility Model Publication No. 60-15461 is bent integrally with the side wall of the drawer. The moving slider made of resin attached to the rear end of the rail is configured to be mounted on the outer surface of the vertical piece of the rail, and projects above and below the rail, respectively. The drawer can be shaken in the vertical and horizontal directions, but since the rail is formed by bending the side wall of the drawer, a complicated and large bending device is required. Further, a groove may be formed on the inner surface of the side wall of the drawer, which may make it difficult to use. Further, since the rail is formed integrally with the drawer, the rail cannot be shared for drawers of different sizes, and the component cost is rather increased. Furthermore, since the moving slide is attached to the outer surface of the vertical piece of the rail, the total protrusion amount of the rail and the moving slide from the drawer side wall is increased, and there is a drawback that the drawer storage space is reduced accordingly. .

Accordingly, an object of the present invention is to provide a rail support.
It is an object of the present invention to provide a drawer opening / closing device which can easily mount the drawer, easily form a rail and attach a moving slide, and can obtain a smooth opening / closing operation of the drawer.
