During the travel of a vehicle, the oil level of lubricating oil is lowered due to the suction by at least a first oil pump and the scraping-up by the rotation of a differential ring gear and so on. In particular, until the oil level becomes equal to or lower than an upper end of a first partition wall, the oil level is lowered due to both the suction by the first oil pump and the scraping-up by the rotation of the differential ring gear and so on, and therefore, a region, that is immersed in the lubricating oil, of the differential device rapidly becomes smaller. Since a suction port of the first oil pump is disposed in a second oil storage portion, the oil level in the second oil storage portion during the travel of the vehicle can be adjusted independently of that in a first oil storage portion.
