Abstract
A power transfer unit for transferring power from a front wheel side to a rear wheel side comprises: a hollow transfer input shaft which is coupled to an engine and through which a right-side front-wheel axle is penetrated; a transfer output shaft disposed to extend in a direction orthogonal to the transfer input shaft; a transfer drive gear provided on an outer periphery of the transfer input shaft; and a transfer driven gear provided on an outer periphery of the transfer output shaft and meshed with the transfer drive gear. It further comprises a damper mechanism configured to absorb a fluctuation in torque input from an engine side into the transfer input shaft. The damper mechanism is disposed such that an intermediate portion and a left end-side portion thereof overlap the transfer driven gear in an extension direction of the transfer output shaft, in top plan view.
