Abstract: A drive unit may include a case comprising an electric motor chamber and a gear chamber; an electric motor comprising a rotor housed in the electric motor chamber; a specific gear housed in the gear chamber; lubricant stored in the electric motor chamber and the gear chamber; and a through hole connecting the electric motor chamber and the gear chamber. An opening of the through hole on a gear chamber side may be positioned so as to face a side surface of the specific gear. A region below a center of the specific gear is defined as a lower region, a part of the lower region that is located rearward of a vertical plane passing through a center axis of the specific gear in a rotation direction of the specific gear is defined as a lower rear region, and the opening may be in the lower rear region.

Abstract: In a catch tank, a partition wall is formed that extends along a vehicle front-rear direction and divides the catch tank in a vehicle width direction in a vehicle-mounted state, which helps prevent oil in the catch tank from flowing unevenly to one of a first space and a second space even when the oil surface of the oil tilts during turn of the vehicle, for example. As a result, an appropriate amount of oil required for lubrication is supplied through a second lubrication hole regardless of tilt of the vehicle or turn of the vehicle.
