Abstract
A dump truck is provided with a frame, hinge pins and a body (). The body is provided on a lower surface of a floor board () thereof with a rail () along a longitudinal direction of the frame. The rail is a hollow structure member comprised of two side rail plates () and a bottom rail plate (). The two side rail plates () extend downwardly from the lower surface of the floor board () of the body and oppose each other with an interval therebetween in a lateral direction of the frame, and the bottom rail plate () is arranged in contact with respective lower end surfaces (-) of these two side rail plates (). The dump truck () satisfies a relationship of Ts<Tb<Tf, where Ts is a thickness of the side rail plates, Tb is a thickness of the bottom rail plate, and Tf is a thickness of a top frame plate (-) of the frame.
