A vehicle drive device includes: a torque converter having an input-side rotating member to which power from a prime mover is input and an output-side rotating member outputting power to drive wheels; an electric motor coupled to the input-side rotating member; a transmission coupled to the output-side rotating member of the torque converter; and a case member housing the torque converter, the electric motor, and the transmission, the case member having an air chamber and an oil chamber, the prime mover and the electric motor being disposed at positions with the torque converter interposed therebetween in an axial direction, the torque converter being housed in the air chamber, the electric motor being housed in the oil chamber the vehicle drive device further comprising a second electric motor coupled to the output-side rotating member of the torque converter, the second electric motor being disposed between the electric motor and the transmission in the axial direction in the oil chamber, an oil pressure generating device being disposed between the electric motor and the second electric motor in the axial direction in the oil chamber, and a drive gear of the oil pressure generating device being coupled to the input-side rotating member of the torque converter via a first shaft disposed in parallel with an axis on an inner circumferential side of the electric motor, a second shaft parallel to the axis being disposed on an inner circumferential side of the first shaft, a stator impeller of the torque converter being coupled via a one-way clutch and the second shaft to a cover member that is a non-rotating member of the oil pressure generating device, and the second shaft and the cover member being coupled, and an oil passage for supplying an operating oil to the torque converter being made up of a gap formed between an inner circumferential surface of the first shaft and an outer circumferential surface of the second shaft. |
