An oscillating hinge bracket 8 is mounted on the lower surface of the side dump door 4, and a fixed hinge bracket 14 is mounted on the side end surface 3 of the floor plate 1 through a hinge shaft 11. A reinforcing piece 16 connects the side end surface 3 of the floor plate 1 and a cylindrical portion 13, and a hinge portion 7 is formed by the fixed hinge bracket 14, the oscillating hinge bracket 8, the hinge shaft 11 and the reinforcing piece 16. The hinge portion 17 is disposed at plural portions in the dent portion 7.
