Abstract
Abstract A slide rail assembly includes a U-shaped guiding rail and a U-shaped gui rail. The guided rail has turned-in portions along the longitudinal free edges of its legs, which turned-in portions engage behind adjacent legs of the U-shaped guiding rail. One leg of the guided rail together with its turned-in portion is recessed from one end of the rail to substantially the center of the rail. The other leg of the guided rail is recessed from the other end of the rail to the center.
