Abstract
A drawer rail includes an outer rail fixed to a furniture item, a sliding rail slidably contained in the outer rail, a ball rail slidably contained in the sliding rail, and an inner rail slidably contained in the outer rail and fixed to the drawer or a keyboard supporter. The sliding rail has a front end extending towards an outermost side of the drawer by which it is pulled outward. A positioning device is fixed on the sliding rail near the front end of the sliding rail. The positioning device has a body and a head having a pair of side slopes that are able to respectively engage with a pair of side walls of a groove defined in a bottom of the ball rail. The positioning device of the invention is able to provide a stable positioning effect for the inner rail, and thus the drawer, when the drawer is pulled to an outermost position.
