PROBLEM TO BE SOLVED: To arrange latch teeth along the upper section of a load carrying platform, make latch claws engage withthe latch teeth surely when the drive cylinder of a slide plate retracts by arranging the latch claws along the shoulder section of a push plate and discharge the bulk cargo placed on the load carrying platform from the rear end of the load carrying plat form by repeating locking and unlocking. SOLUTION: In a truck provided with a cargo unloading push plate 4 which moves toward the rear end section from the drive room on a load carrying platform 2, latch teeth 12 are arranged intermittently at a required pitch on the both side plates 2a of the platform 2, and the latch claws 15 to be engaged with the latch teeth 12 are provided so as to be detachable on both shoulder section 4a of the push plate 4, which are arranged so as to be movable in a specified direction on a slide plate 7 reciprocating in the inside of platform 2. The latch claws 15 are constituted so as to be stopped at positions separated a little from the latch teeth 12 at the corresponding positions when the push plate 4 advances or retracts one stroke of the drive cylinder of the slide plate 7 and to be locked by the latch teeth 12 when the slide plate 7 retracts or advances.
