PURPOSE: A vehicle differential gear device is provided to automatically stop rotation of either side gear and simultaneously transmit a torque to the other side gear when a difference of rotation force between cam side gears is large, thereby inducing the distribution of the torque. CONSTITUTION: A vehicle differential gear device includes pulse rings(10) respectively attached to inner peripheral surfaces of a cam side gear(3) and a differential side gear(4), a clutch cam plate(5) having a plurality of grooves(11), and the differential case(9) mounted with a plurality of balls on an inner peripheral surface, wherein the clutch cam plate is locked when the balls are captured in the grooves.
