ABSTRACT:
A speed increasing/decreasing mechanism is interposed between a left-wheel axle and a right-wheel axle. The mechanism is constructed integrally of a speed increasing mechanism and a speed decreasing mechanism. The speed increasing mechanism is adapted to increase a rotational speed of the left-wheel axle and then to output the thus-increased rotational speed to a first intermediate axle. The speed decreasing mechanism, on the other hand, is adapted to decrease a rotational speed of the left-wheel axle and then to output the thus-decreased rotational speed to a second intermediate axle. A first coupling of the variable transmitted torque capacity type is interposed between the first intermediate axle and the right-wheel axle to transmit drive torque therebetween. A second coupling of the variable transmitted torque capacity type is interposed between the second intermediate axle and the right-wheel axle to transmit drive torque therebetween.
