ABSTRACT:
Arranged within a differential gear case are first and second side gears rotating together with first and second output shafts, respectively; first and second differential gears engaged with one of the first and second side gears and rotatably supported within cylindrical holes, respectively, so as to be partially engaged with each other to move circularly together with the differential gear case; and a viscous coupling capable of transmitting, between a hub rotating together with the output shaft and a housing, a torque in response to the difference in the speed. The outer periphery of the housing is provided with a cam surface to be engaged, in the direction of rotation, with the first and second differential gears to press and bias the first and second differential gears against the inner cylindrical surfaces of the cylindrical holes.
