Abstract
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.
