To arrange a power unit, an electric power conversion unit, and engine-related components compactly, a drive motor, a reduction drive, a generator, and an engine body are integrally arranged in this order in a vehicle width direction of a power unit compartment such that respective heights thereof are substantially the same. An electric power conversion unit, in which a motor inverter, an electric power generation inverter, and a DC/DC converter are integrated, is arranged above the drive motor, the reduction drive, and the generator. Engine-related components such as a low-voltage battery, an air cleaner, and an oil filter are arranged above the engine body.

A vehicle drive system includes a motor (drive motor), a generator, a reduction drive that reduces output of the motor, and a housing. At a position above a motor shaft, an oil passage, through which oil is supplied to each of the motor, the reduction drive, and the generator, is integrally formed with the housing. An oil pipe is attached to the housing and supplies the oil from an oil reservoir to the oil passage. At a position between the motor and the generator, the reduction drive is offset from the motor shaft in a second direction that is orthogonal to the first direction. The oil pipe is located between the motor and the generator in the first direction, and at least part of the oil pipe is located on an opposite side of the reduction drive with the motor shaft being interposed therebetween in the second direction.
