PURPOSE: A center differential secures high differential limiting force and balances tread force between front wheels and rear wheels to distribute basic driving torque. CONSTITUTION: For pinion gears to be placed slantly and transmit power between a differential gear case(3) and front/rear side gears(5, 7) with different driving torque distribution ratios, the diameter of the outer periphery of the differential gear case(3) are increasing from the rear side thereof to the front side thereof by degrees so that the outer peripheral line thereof inclines at a certain angle and the diameters are increased from the rear side gear(7) to the front side gear(5) by degrees so that their teeth lines incline at a certain angle so that the front/rear side gears(5, 7) are engaged with the pinion gears placed slantly. A pinion gear set(13) is placed at a certain angle(α) with the central axis to increase friction torque to achieve high differential limiting force.
