PROBLEM TO BE SOLVED: To easily perform the positioning of a hinge shaft and a support part at a hinge side by fixing the hinge shaft with a hinge main body provided between a pair of support parts to be supported by a pair of brackets provided on the dump body side, and deviating the axis of the support parts and the axis of the fixed part from each other. SOLUTION: Both ends of a hinge shaft 11 are led into each hole part 28a of a pair of brackets 28 fixed to a lower end of a dump body by a fitting member 27, and the hinge shaft 11 is supported by a hinge main body at a central part, and fixed by a hook provided in the hinge main body. The hinge shaft 11 is formed of a round bar, and a small diameter part 11b is formed between large diameter parts 11a provided in both ends, and axes of the support parts 11a and the fixed part 11b are deviated from each other. With this structure, even in the case where the hinge shaft 11 and the support parts of te hinge main body of a three-way dump truck are displaced from each other, the fixed part 11b of the hinge shaft 11 is displaced by rotating the hinge shaft 11 around the axis of the support part 11a so as to easily correct the positional displacement for coincidence.
