PROBLEM TO BE SOLVED: To prevent right and left output shafts from being elongated, to provide excellent vehicle loading performance, to reduce the number of parts, to reduce the size and the weight, to provide compatibility to a conventional device, to easily adjust and set bypass torque, to improve control precision, to provide excellent durability and reliability, and to generate sufficient differential limiting torque with good responsiveness. SOLUTION: A first gear 63 is fixed to either a of right output shaft or a left output shaft from a differential limiting mechanism part provided with a differential limiting multiple disc clutch 59, and second and third gears 65, 66 are fixed to the other output shaft. Fourth, fifth and sixth gears 67, 68, 69 to be meshed with gears 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 gear train is formed of the first and fourth gears 63, 67, the second gear train is formed of the second and fifth gears 65, 68, the third gear train is formed of the third and sixth gears 66, 69, and respective gear ratios are set to 0.9, 0.9×0.9, 1. The connection of a pair of first and second hydraulic multiple disc clutches is controlled, and driving force is directly distributed and controlled between right and left wheels.
