PROBLEM TO BE SOLVED: To simplify a traveling transmission structure and the supporting structure of front/rear traveling wheels 2 and 15, to simplify the turning operation such as direction change, and to improve the turning mechanism. SOLUTION: This working vehicle having a plurality set of the traveling wheels 2 and 15 installed left/right symmetrically is characterized in having a traveling shift mechanism 25 rotating the left/right traveling wheels 2 and 15 in the same direction at an approximately same speed by the traveling shift operation, a turning mechanism 28 steplessly shifting and rotating the left/right traveling wheels 2 and 15 reversely at the approximately same speed by the steering operation, and a left/right differential mechanism 33 transmitting the drive outputs of the traveling shift mechanism 25 and the turning mechanisms 28 to the left/right traveling wheels 2 and 15.
