Abstract
A rotary electric machine and a gear mechanism are housed in a case including a first housing chamber and a second housing chamber separated by a partition wall. The gear mechanism supplies oil to a lubrication target location by scooping up the oil inside the case. A valve body that allows an oil flow from the first housing chamber to the second housing chamber and restricts an oil flow from the second housing chamber to the first housing chamber is attached to an opening that is formed by the partition wall and communicates the first housing chamber and the second housing chamber.
