ABSTRACT:
This invention relates to an apparatus for opening and closing a rear door of a vehicle such as a dump truck. The rear door of the vehicle is bisected into left and right rear door sections. When opened, the bisected left and right rear door sections are moved toward the outsides of the both side walls of the bed of the vehicle by the power of a drive cylinder provided on the lower surface of the floor of the bed of the vehicle, respectively. When the operating rod of the drive cylinder is extended, each of the left and right rear door sections is moved through a single or a plurality of links. Arcuate portions are preferably formed on the inner wall surfaces on the sides of respective out side end portions of the left and right rear door sections so that the door sections, when being opened, can be smoothly moved around the rear edges of said side walls to positions outside the side wall.
