A rotary electric machine (1), a transmission (2), and a differential gear device (3) are disposed coaxially. The transmission (2) includes a first helical gear (HG1) and a second helical gear (HG2) that meshes with the first helical gear (HG1). A case (10) includes a first case member (6) including a stator support portion (61) that supports a stator (11) of the rotary electric machine (1), a second case member (7) that is structured as a separate member from the first case member (6) and forms a gear chamber (C2) that houses the transmission (2) and the differential gear device (3), and a support member (8) that supports the first helical gear (HG1) in an axial direction (L). The support member (8) rotatably supports a rotor (12) of the rotary electric machine (1) via a rotor bearing (B1), and is fixed to the second case member (7).
