A vehicle drive device is provided having a first source of driving force and a hydraulic transmission, into which power is input from the first source of driving force, arranged axially. A motor that transmits power by an electromagnetic action between a stator and a rotor is arranged between the first source of driving force and the hydraulic transmission. The stator is arranged to be radially distant from the rotational center axis of the hydraulic transmission. A small diameter portion formed to have a smaller outer diameter than an inner diameter of the stator is formed at a motor side of the hydraulic transmission and the hydraulic transmission is arranged with the small diameter portion being inserted axially into the inner periphery of the stator. As a result, the axial length of the vehicle drive device is shortened to thereby provide a small-size, lightweight device.
