It is possible to secure the roller brackets with only one fastener, and to reduce the number of parts, labor, and material costs by reducing the area of the roller bracket fixing parts. It is about.

Generally, a sliding door of a wall-mounted cabinet such as a sink or a bath room becomes an inner and an outer door, and a roller sliding on a rail provided on the cabinet body is mounted on the left and right of the upper and lower portions of the door using brackets .

In the prior art of the sliding door, two lines of rails are provided so that the inner door and the rollers provided on the outer door are respectively guided by separate rails. However, this configuration is not suitable for preventing interference between the roller brackets of the inner and outer doors, The length of the upper and lower ends of the inner and outer doors are different from each other in the state where the door is closed. Therefore, the aesthetic appearance of the door is lowered, while the size of the outer door is reduced in the vertical direction The material and the cost are wasted.

As an alternative to such a problem, a one-rail type sliding door in which the rollers of the inner and outer doors use one rail is widely used.

The one rail type sliding door is disclosed in Patent Registration No. 10-1151895 and the like, and as shown in FIGS. 1 and 2 of the present invention, the height of the inner and outer doors 1b and 1c is the same.
