Claims

[Scope of utility model registration request]

A ball is rotatably held between a fixed outer rail with a substantially C-shaped cross section, a fixed inner rail with a substantially U-shaped cross section that is slidably mounted inside the fixed outer rail, and the bent side of both rails. A first drawer rail consisting of a ball retainer, and a second drawer rail having substantially the same configuration as the first drawer rail, are moved to the outer surface of the inner rail on the fixed side of the first drawer rail. In a multi-stage rail such as a drawer having a structure in which the outer surface of the inner side rail is fixed, the fixed inner rail of the first drawer rail is in its maximum extension state and the first drawer rail is attached to the inner surface of the intermediate portion of the fixed outer rail of the first drawer rail. A fixed side stopper is provided which elastically abuts and engages with the rear end stopper of the fixed side inner rail of the second drawer rail, and on the rear inner surface of the movable side inner rail of the second drawer rail,
A moving side stopper is provided which elastically abuts and engages with the rear end stopper of the moving side outer rail of the second drawer rail when the entire moving side outer rail of the second drawer rail is housed in the moving side inner rail. Features multi-stage rails such as drawers.
