A dishwashing machine has a tank defining a cleansing chamber, a rack within the chamber having a bottom and parallel sides and elongated tracks extend between the sides of the rack and the chamber side walls. Each track includes longitudinally extending guideways, one on each side of the track. Rollers mounted on the tank side walls are received within one guideway of each track, and rollers mounted on each side of said rack are received within the other guideway of the corresponding track. A bumper member mounted on each end of each said track has a retaining tab formed as an integral extension to the bumper member, and a lock part on the tab is engaged through a hole in the track. A retaining pin extends through the ends of the track and through the bumper member. The pin has a head preventing the pin from passing completely through the track and the tab extends over the head of the pin.
