PROBLEM TO BE SOLVED: To provide a structure for preventing backlash of a tray of a transportation cart which is manufactured with a simple structure, and reliably prevents the backlash or drawing out of a tray of a transportation cart, even when the cart vibrates or applied with moving inertia or centrifugal force during urgent transportation thereof. SOLUTION: Technical means like followings is adopted. At the periphery of an opening of the tray 1, a flange part 11 is formed, and the flange part 11 is supported slidably on the lower guide members 21 of a pair of right and left guide rails 2 arranged respectively on the side surfaces of a cart body. On both ends of the lower guide members 21 of the guide rails 2, stopper protrusions 21a are formed respectively with which each end of the flange part 11 can collide. On the side wall surface of the guide rail 2, a slit groove 22 is formed which is folded back in a U-shape. On the inner side surface surrounded by the slit groove 22, a leaf spring 23 is formed on which laterally projecting part 23a is provided. COPYRIGHT: (C)2011,JPO&INPIT
