摘要：PROBLEM TO BE SOLVED: To provide a work vehicle provided with a traverse system capable of easily fixing a steering wheel in a work vehicle capable of traversing. SOLUTION: A pair of a right and a left front wheels 3 and rear wheels 4 are provided to be direction-changeable by 90 deg. to a car body 2, and direction changing means 30 and 50 are respectively provided for them. The rear wheel direction changing means 50 comprises a rotation cylinder 51, and a hydraulic cylinder 52 for changing the direction of the rear wheels movable in a car width direction by actuation of the rotation cylinder 51. An opening/ closing valve means 70 is provided in a hydraulic circuit 66 from an orbit roll unit 65 interlocked with the steering wheel 15 to the rotation cylinder 51. The rear wheel direction changing means 50 disconnects the hydraulic circuit 66 to the rotation cylinder 51 in the rear wheel direction changing means 50 in changing from normal travel to traverse, so that the steering wheel 15 can be easily fixed without depending on precision, strength, and adjustment. Maintenance performance of a rear wheel direction changing system can thus be improved, thereby improves work efficiency.
