Claims

[Scope of utility model registration request]

At least an outer member with a substantially C-shaped cross section, an inner member with a substantially C-shaped cross section that is slidable on the outer member, and a ball retainer that rotatably holds the ball between the upper and lower bent edges of both members. In the rail such as a drawer having a brake device attached to the rear end of the outer member, the brake device is made of an elastic material and is formed by making the rear end of the base plate of the inner member protrude inwardly. a mounting base that is detachably attached to the member stopper; and a mounting base that is connected to the upper and lower ends of the mounting base,
It consists of a brake leg that protrudes forward along the inner surface of the upper and lower bent edges of the outer member, the brake leg has a dimension between the inner surfaces that is smaller than the dimension between the upper and lower bent edges of the inner member, and an elastically deformable protrusion formed from the mounting base. and is connected to the elastically deformable protrusion, has an inner surface facing forward and gradually approaches the upper and lower bending edges of the outer member, and has a tip that is slightly smaller than the gap formed by the ball guide groove of the outer member and the inner member. and has an inclined surface portion, and is characterized in that when the inner member is completely housed in the outer member, the elastically deformable protrusion deforms and the brake leg portion is tightly fitted and pressed into the gap. Brake device for rails such as drawers.
