Zusammenfassung:	PROBLEM TO BE SOLVED: To shorten the size in a rotation axial direction in a final reduction gear of a working vehicle. SOLUTION: The final reduction gear 4 reduces and transmits the rotation input from a motor to front wheels, and includes: a planetary gear type reduction gear 39; a case 18; and two tapered roller bearings 59, 60. The planetary gear type reduction gear 39 includes: a sun gear 50 in which the rotation from a motor 3 is input; a plurality of planetary gears 51 meshed with the sun gear 50; a carrier 52 on which the plurality of planetary gears 51 are mounted; and a ring gear 53 in which the plurality of planetary gears 51 are meshed so as to transmit the rotation to the front wheels. The case 18 is provided with the ring gear 53 and stores the planetary gear type reduction gear, in which the front wheels are fixed. The two tapered roller bearings 59, 60 are arranged at both sides of the planetary gear 51 in the rotation axial direction, and rotatably support the case 18 with resect to the carrier 52.
