Vehicle drive apparatus

A vehicle drive apparatus, comprising:

• a rotating shaft extending along an axial line in a first direction;
• a planetary gear mechanism including a sun gear provided around the rotating shaft, a ring gear provided around the sun gear, a planetary gear between the sun gear and the ring gear to engage with the sun gear and the ring gear, a planetary shaft extending parallel to the axial line to rotatably support the planetary gear, and a carrier configured to support the planetary shaft;
• a rotor including a plate portion formed in a substantial ring shape adjacent the planetary gear and a cylindrical portion connected to an outer periphery of the plate portion to transmit a torque through the planetary gear mechanism from the rotor to the rotating shaft or from the rotating shaft to the rotor;
• and
• an oil passage forming part configured to form an oil passage so as to lead a lubricating oil supplied from a hydraulic power source through the plate portion to the planetary gear,
• wherein the oil passage forming part includes plate through holes and a shaft through hole,
• the plate through holes are formed axially in the plate portion so as to penetrate the plate portion and arranged in a circumferential direction along a circle with a radius defined as a distance from the axial line to the planetary shaft, and
• the shaft through hole is formed inside the planetary shaft so as to penetrate the planetary shaft from an end surface to an outer peripheral surface of the planetary shaft.
