Abstract
A vehicle drive device that has a stator and a rotor disposed on the inside of the vehicle wheel and drives the wheel, wherein the whole stator can be intensively cooled without causing an increase in production costs. The vehicle drive device comprises: the stator that has a stator core () and a hollow stator coil (), is arranged on the inside of the rotating vehicle wheel (), and electrically generates magnetic force; the rotor that has permanent magnets () connected to the wheel (), and applies rotational force to the wheel () using the magnetic force of the stator; a cooling medium that flows through the hollow section of the stator coil (); and a first radiator unit () that releases heat from the cooling medium.
