The vehicle body 2 is equipped with a hydraulically operated transmission 10 connected to the vehicle body 2 through an operation valve (2), and the left and right wheels 22, 22 on one of the front and rear sides of the vehicle body 2 can be raised and lowered integrally and contrarily with respect to the vehicle body. When installed, the hydraulic cylinder 2 expands and contracts in a reverse manner as the left and right wheels 22 and 22 move up and down in opposite directions.
5.25 is connected by a flow path 26 provided with an on-off valve 27, and a pressure fluid supply flow path 28 for closing the on-off valve 27 is connected, and the left and right wheels 22.22 are moved up and down in opposite directions. The traveling part structure of a working vehicle is configured to be able to be freely switched between a state and a fixed state, and the fluid pressure pump P is located at a position outside a speed change range including a neutral position N of the operation valve V. A traveling part structure of a working vehicle, characterized in that - a flow path C for connecting the pressure fluid supply flow path 28 to the pressure fluid supply flow path 28 is provided.
