Second Embodiment (FIG. 4) In the second embodiment, the elastic stopper 5 of the first embodiment comprises a mounting portion 51, a stopper portion 52 and an operating portion 55, whereas the inner rail 2 In order to maintain the most pulled out state, an elastic stopper 6 different from that of the first embodiment is used.

That is, the elastic stopper 6 of the second embodiment
Is a mounting portion 61 connected to the rear inner surface of the inner rail 2.
And the rail stopper 1 formed integrally with the mounting portion 61.
A stopper 64 having a guide slanting portion 62 having a size larger than that between the four and the 14 and inclined toward the outer rail 1 side and projecting obliquely in the direction of the inner rail 2 at the front end; Notches 63, 63 are formed so that the distance between the rail stoppers 14, 14 is shorter than the distance between the rail stoppers 14, 14 facing the location.

That is, according to the elastic stopper 6, even when the front end abuts on the rail stoppers 14, 14 when the inner rail 2 is pulled out, the elastic stopper is displaced in the direction of the inner rail 2 by the guide inclined portion 62. And pulled out forward.

When the notches 63, 63 of the elastic stopper 6 are located at the rail stoppers 14, 14, the elastic stopper 6 is displaced toward the outer rail 1 by elasticity, and cuts off with the rail stoppers 14, 14. Notch 63,
63 is engaged and the movement of the inner rail 2 stops. At this time, the inner rail 2 is kept pulled out without moving in the front-rear direction.

On the other hand, when pulling out the drawer or the like from the main body of furniture or the like or storing the drawer or the like, the front end of the elastic stopper 6 is pushed toward the inner rail 2 so that the notch 63 is located inside the rail stoppers 14 and 14. The inner rail 2 is pulled out or inserted from the outer rail 2 while maintaining the state where the rail 2 is positioned on the substrate 22 side.

In the first and second embodiments, the rail such as the drawer is constituted by one outer rail 1 and the inner rail 2. However, when a plurality of rails are combined and used as one rail, the drawer is used. With the inner rail on the side where the etc. are attached,
It goes without saying that the present invention may be used for an outer rail that is slidable with the inner rail.

[0022]

As described above, since the front end of the board of the outer rail is cut and raised in the direction of the inner rail to serve as a rail stopper, a separately formed member is welded to the front end of the outer rail as in the prior art. No time is required,
Cut-and-raise can be made only by pressing, so it is very inexpensive. In addition, since the rail stoppers are formed facing each other at a predetermined interval, the elastic stopper of the first embodiment does not need to form any engaging holes or the like as in the prior art, and a portion larger than the distance between the rail stoppers. Thus, only a small part is required, and the structure is simple and can be manufactured at low cost. Further, in the second embodiment, the projecting state of the inner rail can be maintained only by forming a cutout portion in which the distance between the elastic stoppers is smaller than that between the rail stoppers, in the elastic stopper formed to have a size larger than that between the rail stoppers. Can be done.
