Abstract:
A drive apparatus to be mounted on a vehicle includes a motor body including a rotor to rotate about a central axis extending in a horizontal direction perpendicular to a direction of travel of the vehicle, and a stator radially outside of the rotor, a housing including a housing portion to house the motor body, oil in a vertically lower region of the housing portion, and a pump to move the oil from the vertically lower region of the housing portion to feed the oil to the motor body. A liquid surface of the oil in the vertically lower region of the housing portion approaches the central axis to bring the oil into contact with the rotor as a result of the vehicle being inclined forward or rearward in the direction of travel.
