PURPOSE:To prevent the shortage of the differential limiting torque by controlling the rate of increase of the fluid pressure so as to gradually increase as the revolution speed difference between the right and left wheels increases, thus compensating the reduction of the frictional coefficient of a frictional clutch accompanied by the revolution speed difference between the right and left wheels. CONSTITUTION:A frictional clutch means 4 is installed between the driving input and output parts of a differential means 3 for transmitting the engine driving power in distribution into the right and left driving wheels 1 and 2, permitting differential movement, is installed. An actuator 6 which is connected to the frictional clutch means 4 and controls the fluid pressure supplied from a fluid pressure generating means 5 is controlled by a control means 8 on the basis of the signal supplied from an input sensor 7 for detecting the state of a car. Further, a revolution speed difference sensor 701 between the right and left wheels as input sensor 7 is installed. The control means 8 is provided with the control characteristic in which the rate of increase of the fluid pressure gradually increases as the revolution speed difference between the right and left wheels increases.
