Abstract:

To enable the imparting of relatively rotational force to right and left axle shafts even at the reverse traveling without enlarging a device.

The right and left drive force distributing device is comprised of a differential to distribute the drive force input from an engine to the right and left axle shafts, a hydraulic motor to impart the relatively rotational force to the axle shafts, and a hydraulic mechanism provided with a hydraulic pump 61 to rotate the hydraulic motor rotated by the drive force from the engine. The hydraulic pump 61 is comprised of a pump shaft 66, a swash plate 67 supported freely to tilt, a swash plate tilt holding mechanism 70 to tilt the swash plate 67 to one side or the other side corresponding to the rotation direction of the pump shaft 66, and a working fluid supply mechanism 80, which has a cylinder block 81 having a piston 82 advancing and retreating in a cylinder hole 83 coming in contact with a tilted face 67a of the swash plate 67 for the front end, and supplies the working fluid sucked from a tank T into a suction port of an operating control valve when the pump shaft 66 rotates in the positive or reverse direction, and the piston 82 makes a piston motion.
