PROBLEM TO BE SOLVED: To provide a body loading/unloading vehicle capable of preventing the rear wheels of the vehicle from levitating certainly when a body is unloaded without provision of any grounding sensor. SOLUTION: The body loading/unloading vehicle includes a hydraulic circuit 29, and when a sensor senses that the forefront of the body lies behind a tilting shaft of a tilting frame, the hydraulic circuit 29 refrains from supplying the oil pressure to a tilting cylinder 4 from a pump 31 and puts the oil chamber on the back pressure side when the tilting frame is tilted in the body unloading operation, in communication with a tank 30 through a throttle valve 34a. In this condition, the load of the body or the cargo gives a torque to the tilting frame, and the tilting cylinder 4 is operated to tilt the tilting frame again. When the rear end of the tilting frame grounds, the torque nullifies, and the tilting cylinder 4 stops operating naturally. COPYRIGHT: (C)2006,JPO&NCIPI
