An automatic tailgate opening and closing device for a disclosed dump truck comprises: a loading box which has brackets fixed at the top of the rear of both side walls; a tailgate which has rotating plates fixed on both sides of the top thereof, and rotating shafts fixed on the rotating plates to rotate vertically on brackets of the rotating plates, and which when the loading box is tilted backward, opens the rear of the loading box by self-weight around the rotating shaft while being perpendicular to the ground, and when the loading box is placed on a vehicle frame, closes the rear of the loading box; an opening and closing unit which can open or close the tailgate in the state in which the loading box is placed on the vehicle frame; and a restriction unit which supports the tailgate opened by the opening and closing unit. Thus, the automatic tailgate opening and closing device can open and close the rear of the loading box by linking the loading box with the dumping operation.
