PROBLEM TO BE SOLVED: To provide a differential limiting device capable of increasing a capacity of a clutch to obtain a sufficiently large differential limiting force. SOLUTION: The differential limiting device comprises a housing 2 rotated by a driving force of a driving source, a differential mechanism 3 having one pair of output gears 3A, 3B to distribute torque from the housing 2 to a pair of output shafts differentially, a clutch 4 disposed around the pair of output gears 3A, 3B and having an inner clutch plate 4A and an outer clutch plate 4B as an annular frictional plate to restrict the differential movement of the differential mechanism 3, and an output mechanism 5 driving the clutch 4. The output mechanism 5 includes a first cam 52C having an outer diameter corresponding to an outer diameter of the inner clutch plate 4A and the outer clutch plate 4B and moving along an axial direction, and a pushing pin 35 as a transmitting member transmitting the axial movement of the first cam 52C to the clutch 4.
