Patent ID: 11137061

Abstract:
A motor unit includes a motor including a rotor, a reduction gear including an intermediate gear to rotate about an intermediate axis, a differential including a ring gear arranged to rotate about a differential axis, a housing, oil in a vertically lower region of a housing space, and an oil passage to feed the oil to the motor. At least a portion of the ring gear is lower than a liquid surface of the oil in the vertically lower region of the housing space. A motor axis, the intermediate axis, and the differential axis to extend in parallel with one another in a horizontal direction. Each of the intermediate axis and the differential axis is lower than the motor axis. A line segment imaginarily joining the motor axis and the intermediate axis, a line segment imaginarily joining the intermediate axis and the differential axis, and a line segment imaginarily joining the motor axis and the differential axis when viewed in an axial direction of the motor axis are defined as first, second, and third line segments, respectively. The first line segment extends substantially along a vertical direction. The second line segment extends substantially along a horizontal direction.
