ABSTRACT:
A power transfer system which distributes a power of the engine to front and rear wheels in a vehicle. The power transfer system comprises a first input shaft whose one end portion is in butt connection with an input shaft from an engine and whose other end portion is supported to a ball bearing fixed to a housing. A friction clutch is installed to the first input shaft such that the power to the first output shaft is transferred to a second output shaft through an endless chain according to the engagement of the friction clutch. A ring groove is formed at an outer peripheral portion of the first output shaft, and a ring member is installed to the ring groove so as to be in contact with a side surface of the ball bearing. Therefore, a thrust load applied to the first output shaft due to the operation of the friction clutch is securely received by the ball bearing through the ring member.
