WORKING VEHICLE

PROBLEM TO BE SOLVED: To provide a working vehicle capable of steering front wheels and rocking the right and left front wheels individually in the vertical direction of the vehicle, enhancing the fuel consumption by improving the power transmission efficiency from a front wheel driving shaft to the front wheels, and enhancing the workability such as the assemblability and the maintenance property. SOLUTION: A front wheel driving shaft 101 is fitted to a sun gear 116 provided on a center part of a supporting case 103 of right and left front wheels 23 via universal joints 108, 110. The front wheels 23 are rotated by the interlocking actions of a sun gear 116, a plurality of planetary gears 117 engaged with the sun gear 116 and arranged around the sun gear 116, and a ring gear 118 engaged with the planetary gears 117 so as to surround the outer peripheries of the planetary gears 118. A planetary carrier 119 supporting the plurality of planetary gears 117 is fixed to a supporting case 103, and the planetary gears 117 are supported by the planetary carrier 119 and the supporting case 103.
