PURPOSE:To prevent a rear dump door from falling even when a cargo box is dumped down by providing a stopping member on an operating device which rotates a hook by means of lifting up and down of said cargo box and restraining said stopping member from moving. CONSTITUTION:A stopping member 18 is fixed to the lock 14 of an operating device 9, and a swinging member 19 which is engaged and disengaged with this stopping member 18 is rotatably provided on the lower part of a cargo box 1. When an operating lever 20 is rotated clockwise, the bell-crank 21C of a dead point mechanism 21 is also rotated clockwise causing the dead point mechanism 21 to be in a locked condition, and a rotary member 24 and a swinging member 19 rotate counterclockwise via a rod 23, causing the stopping member 18 to be engaged with the swinging member 19.
