PURPOSE:To reduce the dimension of a power transmission device for vehicle which supplies and receives a torque between wheels by a pair of hydraulic clutches which can transmit the torque each other. CONSTITUTION:The ring gear 4 of a differential gear device D is connected with an engine E, and a sun gear 5 and a planetary carrier 8 are connected with the left and right output shafts 9L and 9R, respectively. On a carrier member 11 which is fitted in a rotatable manner with the left output shaft 9L, the first and the second pinions 13 and 14 which are integrally formed and have the respective pitch diameters are supported, and the first pinion 13 is connected with the right output shaft 9R, and the second pinion 14 is connected with the left output shaft 9L. If, in the rightward turn, a hydraulic clutch Cd is engaged, the carrier member 11 is decelerated, and the left front wheel WFL increases speed, and the torque is transmitted to the left front wheel WFL. In the leftward turn, if a hydraulic clutch Ca is engaged, the carrier member 11 increases speed, and the right front wheel WFR is accelerated, and the torque is transmitted to the right front wheel WFR.
