PROBLEM TO BE SOLVED: To provide a vehicular right and left driving force distributing device prevented from being enlarged in the lateral direction, having excellent loading performance, the small number of parts, the small size, the light weight, mounting compatibility with the conventional one, and a differential limiting function, favorable for cost, able to easily adjust and set bypass torque, having high control precision and excellent durability and reliability. SOLUTION: A composite planetary gear-type differential limiting device is provided, a first gear 62 is fixed to a differential case 51 of a differential limiting device, a second gear 63 is fixed to a carrier 53, a third gear 64 is fixed to a right drive shaft 17. Fourth, fifth and sixth gears 65, 66, 67 to be meshed with a gear on the same rotational axis are arranged on the same rotational axis parallel to the rotational axis, and a pair of clutches are provided. The first and fourth gears 61, 65, the second and fifth gears 62, 66, and the third and sixth gears 63, 67 form first, second and third gear trains, respective gear ratio is set to 0.9, 1, 1, connection of first and second hydraulic multiple-stage clutches 73, 77 is controlled, and driving force is distributed and controlled between right and left shafts 16, 19.
