The motor unit includes: a motor having a motor shaft that rotates around a motor axis extending along a horizontal direction; a gear section connected to the motor shaft on one side of the motor shaft in an axial direction; a housing that houses the motor and the gear section; and an oil contained in the housing. The housing includes a motor housing section that has inside a motor chamber for housing the motor, and a gear housing section that has inside a gear chamber for housing the gear section. The housing is provided with an oil passage along which the oil circulates for cooling the motor. A pump that supplies the oil to the motor is provided in a channel of the oil passage. The pump has a pump motor. A rotation axis of the pump motor is parallel to the motor axis.

A cooling mechanism for a vehicle electric motor. The cooling mechanism includes: a coolant oil passage provided between a rotor core and a rotor shaft of the electric motor; an oil supply passage provided inside the rotor shaft and communicating with the coolant oil passage; and at least one first discharge port and at least one second discharge port provided in respective first and second end plates disposed on respective opposite sides of the rotor core. The coolant oil passage includes a first passage portion communicating with the at least one first discharge port, and a second passage portion communicating with the at least one second discharge port. Each of the at least one first discharge port is located in a position that is different from a position of any one of the at least one second discharge port as seen in an axial direction of the rotor shaft.
