PURPOSE:To dischare cargos far from the rear wheel by supporting a rear flat door at the bottom edge and by allowing the door to open or close. CONSTITUTION:A rear flat door 7 is installed on a floor 4a of a packing box 2 by a shaft 11 in such a manner that the door may be rotated backward. An interlocking means 14 comprises links 15 and 16, a rod 14, a roller 20, and a rail 22, and allows opening and closing motion of the flat door 7 in proportion to the inclining motion of the packing box. As the flat door 7 opens and closes on the axis of the bottom edge of the door 7, The cargos are discharged, while sliding on the flat door, thus setting the discharge position far rearward. Therefore, the cargos can be dumped out without approaching the edge of road. |
