There is provided a first and second bearing supporting a clutch case at first and second axial sides in a radial direction, a rotor of a rotary electrical machine is supported by the clutch case, a gap between an outer peripheral face of a pump drive shaft 10 and an inner peripheral face of a drive shaft insertion hole 90c is a distribution passage L of oil flowing from a pump chamber 18a to the first bearing 51, and a distribution passage diameter difference, which is a difference between a diameter Φa of the outer peripheral face of the pump drive shaft 10 and a diameter Φc of the inner peripheral face of the drive shaft insertion hole 90c in the distribution passage L, is set so that the distribution passage L functions as a narrowed portion which limits a flow rate of oil.
