Abstract: Disclosed is a drawer sliding device. The drawer sliding device is configured such that when a drawer is pulled out, an intermediate rail and an inner rail are moved together. Therefore, the load support capacity of a drawer slide can be enhanced and the drawer can be smoothly pulled out. The drawer sliding device may be designed such that the intermediate rail can be extended to a position above an operating rail. In this case, the range of the operation of the automatic closing means can be increased without a reduction in the structural strength of the rail. Furthermore, in the present invention, the drawer slide is provided with the automatic closing means. Therefore, when the drawer is retracted to a predetermined range or more, the drawer can be automatically retracted to a completely closed position, and the drawer in the closed state can be prevented from being undesirably opened.
