  "textContent": "An in-wheel motor vehicle drive device includes an electric motor driving a drive gear, and the drive gear provided with a gear portion configured to receive drive force of the drive gear and a first wall surface extending along a direction orthogonal to an extending direction of a rotation center axis of the gear portion, the first wall surface for forming a pump chamber. The in-wheel motor vehicle drive device further includes a hub configured to transmit the drive force to the wheel, and an oil pump driven by the electric motor. The oil pump includes an oil pump cover including a second wall surface facing the first wall surface of the pump chamber, and a pump rotator arranged at a space between the first wall surface of the driven gear and the second wall surface of the oil pump cover, the pump rotator integrally rotating with the driven gear.",
