Abstract
A rotary electric machine, a transmission, and a differential gear device are disposed coaxially. The transmission includes a first helical gear and a second helical gear that meshes with the first helical gear. A case includes a first case member including a stator support portion that supports a stator of the rotary electric machine, a second case member that is structured as a separate member from the first case member and forms a gear chamber that houses the transmission and the differential gear device, and a support member that supports the first helical gear in an axial direction. The support member rotatably supports a rotor of the rotary electric machine via a rotor bearing, and is fixed to the second case member.
