An intermediate wall is provided with a return oil hole through which oil discharged from a friction engagement device returns toward an oil reservoir. A chain drive is disposed adjacent to the intermediate wall. The chain drive transmits a driving force from an input member and/or a rotary electric machine to an oil pump. There is provided an oil guide through which oil flowing through the return oil hole is guided to a region other than a chain placement region inside a case. The chain placement region is a region where a chain of the chain drive is placed.

Vehicle drive apparatus that reduces or prevents an increase in oil agitation caused by a chain

A vane pump that includes a first communication passage that extends along an outer periphery of the cam ring and that guides a fluid that has not flowed into the first suction port from the first inflow passage to the second suction port; a second communication passage that extends along the outer periphery of the cam ring on an opposite side of the first communication passage with respect to the rotor and that guides a fluid that has not flowed into the second suction port from the second inflow passage to the first suction port; and a rectifying portion that guides the fluid from the second inflow passage so that the fluid flows into the second suction port along the outer periphery of the cam ring.

Vane pump including fluid communication passages for routing fluid received from two inflow passages around outer peripheral surface of the entire perimeter of the cam ring
