Patent attributes
A vehicle drive apparatus including a rotor having a plate portion formed in a substantial ring shape to cover a planetary gear from above and a cylindrical portion erected from an outer periphery of the plate portion to transmit a torque through a planetary gear mechanism to a rotating shaft, and an oil passage forming part forming an oil passage so as to lead a lubricating oil supplied from a hydraulic power source from above the rotor through an upper surface of the plate portion to the planetary gear. The oil passage forming part includes plate through-holes formed vertically in the plate portion and a shaft through-hole formed inside the planetary shaft from an upper surface to an outer peripheral surface thereof. The plate through-holes are arranged along a circle defined a distance from the axial line to the planetary shaft as a radius.
