Abstract
A vehicle drive device includes a traction motor having an output shaft that is hollow, a speed reducer coupled to the output shaft, a differential gear that distributes a drive force of the traction motor transmitted through the speed reducer to a pair of drive wheels, and a transmission shaft that extends through a through hole of the output shaft along an axial direction of the traction motor and is spline-fitted to a side gear of the differential gear by spline provided on an outer peripheral surface of a first end portion of the transmission shaft. The transmission shaft includes a first flow path that extends along the axial direction and a second flow path that has a first end that is open to the first flow path and the second end that is open to the outer peripheral surface of the transmission shaft.
