Abstract:
A vehicle drive device includes: a rotary electric machine; a drive transmission mechanism provided in a power transmission path connecting a rotor shaft of the rotary electric machine and a wheel; a first hydraulic pump driven by a driving force transmitted through the power transmission path; a second hydraulic pump driven by a driving force source independent of the power transmission path; a first oil passage that supplies oil discharged from the first hydraulic pump to a rotor bearing that supports the rotor shaft such that the rotor shaft is rotatable; and a second oil passage that supplies oil discharged from the second hydraulic pump to an inner peripheral surface of the rotor shaft.
