PROBLEM TO BE SOLVED: To provide a cargo box for a dump truck of which water tightness is assured in the state that a tail gate is closed.SOLUTION: A cargo box 5 for a dump truck comprising a cargo box body 10, a tail gate 30, and a drive cylinder 50, the cargo box body 10 comprises a tail gate support part 12 which supports the tail gate 30, an elastic body cover 18 which is covered on a rear end opening edge of the cargo box body 10, and the rear end opening edge of the cargo box body is so obliquely configured that an upper part thereof is positioned on a front side with respect to a lower part in a side view. The tail gate 30 comprises a gate plate 31, and an arm 32 which is supported by the tail gate support part 12 and is connected to the cargo box body 10, and which has a cylinder connection part 36 which rotatably supports a tip of an output rod 55 of the drive cylinder 50. The cargo box is so configured that by contraction of the drive cylinder 50, the gate plate 31 is tightly adhered to the elastic body cover 18 of the cargo box body 10, thereby closing a rear end opening.SELECTED DRAWING: Figure 3
