In addition, the cost is high and it is not easy to carry out daily maintenance such as detaching from the cabinet of the drawer and cleaning.

Further, the drawer-side rail is attached to the lower position of the drawer side wall for the reason of manufacturing the mold, especially in the case of a plastic integrated drawer or the like. On the other hand, for drawers that are molded using a mold such as plastic, the width between the side walls of the drawer is lower than that of the upper part because the mold removal taper is taken in the depth direction of the drawer. Will be narrow. Therefore, when the width of the upper part of the drawer is constant, the lower the space between both side walls becomes narrower as the depth increases, which causes the horizontal position of the cabinet rail to change and the position adjustment to adjust it. Bracket is required. Also, when fixing the horizontal mounting position of the cabinet side rail, it is necessary to change the width of the upper part of the drawer.
