PROBLEM TO BE SOLVED: To transmit power to the right and left axles even when a clutch body on the turn inside is cut off and to improve maneuverability by providing a transmission torque limiter weaker than at least the maximum braking force between the right and left axles in a work vehicle provided with a side clutch type steering/braking device. SOLUTION: Transmission power is applied to a transmission shaft 12 in a transmission 10 from a prime mover via a gear 14 or 16, and the transmission power is transmitted to a final transmission shaft 18 via the meshing of gears 20, 22. The final transmission shaft 18 is provided with a pair of right and left slide type clutch bodies 24, and the rotation of the final transmission shaft 18 is transmitted to the right and left axles 32 via gears 34, 34 invariably meshed with the gear sections 26 of the clutch bodies 24. A multi-disk torque limiter 38 is provided between the right and left axles 32, 32. When an operation lever is operated to disengage one clutch body 34 from the gear 22, transmission power can be applied to the axle 32 on the side that the clutch body 24 is disengaged from the other axle 32, and the straight travel of a machine body is guaranteed.
