Abstract
A motor unit includes a motor including a rotor to rotate about a motor axis extending in a horizontal direction, a differential connected to the motor, a housing including a housing space to house the motor and the differential, oil in a vertically lower region of the housing space, and an oil passage to feed the oil from the vertically lower region of the housing space to the motor. A pump is fixed to an outer peripheral surface of the housing and is located in a channel of the oil passage. The pump is on an opposite side of the motor axis with respect to the differential when viewed in an axial direction of the motor axis.
