An upper rotating arm is pivotally supported on the upper end of the door, and one end is attached to the side wall so that when the upper rotating arm rotates, the rear door can be opened approximately 90 degrees and stored below the loading platform. A rear door opening/closing device for a dump truck, comprising a lower rotating arm which is pivotably supported and whose other end is pivoted to the lower end of the rear door. (2) a bending link pivotally supported at an appropriate location on the loading platform and connected to the chassis side via a tension spring;
It is connected to this bending link via a connecting rod, and one end is pivoted to the side wall of the loading platform so as to rotate as the loading platform rotates, and the other end is pivoted to the upper end of the rear door. One end of the supported upper rotating arm is pivoted to the side wall and the other end of the rear door is pivoted to the side wall so that the rear door can be opened approximately 90 degrees as the loading platform rotates and stored under the loading platform. A rear door opening/closing device for a dump truck consisting of a downward rotating arm pivotally supported at the lower end.
