Abstract
Movable and stationary rails are of complementary cross sections, the movable rail being generally C-shaped with grooved side wall portions, the stationary rail having an elongate flat upper plate whose side edge portions constitute guide edge portions. The side edge portions of the stationary rail are spacedly received in the grooved side wall portions of the movable rail. Metal rollers are disposed between major flat portions of the movable and stationary rails. A plastic slider is secured to each of the guide edge portions and so shaped as to be neatly and slidably received in the corresponding grooved side wall portion of the movable rail. The plastic slider has an opening through which an outside edge wall of the guide edge portion is exposed. A metal ball is rotatably received in the opening in such a manner that diametrically opposed ends thereof are contactable with the outside edge wall and an inner surface of the corresponding grooved side wall.
