Abstract
A vehicle driving apparatus includes a rotating shaft driven by the power source, a fluid pump driven by the rotating shaft. The fluid pump includes a rotor rotated by the rotating shaft, and a case. The case includes a fluid discharge port provided on an inner peripheral surface of an insertion hole through which the rotating shaft is inserted. The rotating shaft includes an attachment portion fittable to a shaft hole, and an internal flow path. A supply groove communicating with the internal flow path is provided on an outer peripheral surface of the rotating shaft. The fluid pump is attached to the attachment portion of the rotating shaft such that positions of the discharge port and the supply groove in an axial direction of the rotating shaft overlap each other. The attachment portion is provided on each of both sides of the supply groove in the axial direction.
