Abstract
A vehicle drive device configured with reduced axial dimensions, while still having appropriate lubrication. The vehicle drive device is configured with an input shaft coupled to an engine, a rotary electric machine, and an output shaft coupled to wheels. A power transfer mechanism couples input shaft, the rotary electric machine, and the output shaft. A case houses at least the rotary electric machine and the power transfer mechanism. An oil reserving portion capable of reserving oil supplied by rotation of the power transfer mechanism is provided above the rotor shaft inside the case. A communication oil passage is oriented between the oil reserving portion and an inner circumferential space formed inside the rotor shaft. The rotor shaft is disposed to be inserted into the inside housing space, and has a supply communication hole that communicates between the inner circumferential space and the inside housing space.
