Abstract
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.
