Abstract
In a vehicle power unit, a differential gear () is housed in an interior of a motor housing () with an electric motor () and a reduction gear (), an output shaft () extending from the differential gear () toward a vehicle width direction is housed in the interior of the motor housing, and an end part thereof in the vehicle width direction is supported on the motor housing via an output shaft bearing (). Since the motor housing has a space () part between the electric motor and the output shaft, and oil that has lubricated the electric motor and been scattered passes the space part and is supplied to the output shaft bearing, the output shaft bearing supporting the output shaft of the differential gear can be reliably lubricated with a simple structure without forming within a wall part of the motor housing an oil passage for lubrication, without disposing in the interior of the motor housing an oil pipe for lubrication, and without carrying out lubrication using a lubricant such as a grease.
