摘要： 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.

摘要： A vehicle includes: a floor panel; an under cover disposed below the floor panel in the vehicle; a parking lock mechanism, disposed between the floor panel and the under cover, switching, using an actuator, a locked state for constraining rotation of a wheel and an unlocked state for not constraining rotation of the wheel; and a parking lock manual releasing mechanism, disposed between the floor panel and the parking lock mechanism, switching, when the parking lock mechanism is in the locked state, the state of the parking lock mechanism to the unlocked state on a basis of manual operation of an operation portion. Further, the under cover includes a visual recognition hole for viewing the operation portion.
