摘要： A first case portion includes an end wall portion disposed on a first axial side with respect to a transmission. A second case portion is disposed on the first axial side with respect to a rotor of a rotary electric machine, and includes a first support portion that supports a rotor shaft and a second support portion disposed on a second axial side with respect to the rotor of the rotary electric machine to support the rotor shaft. The second support portion includes a bearing attachment portion to which a rotor bearing for supporting the rotor shaft is attached, and radially extending portion that extends from bearing attachment portion toward an outer side in a radial direction. A speed reducer is disposed between the radially extending portion and the end wall portion in axial direction to face the radially extending portion and the end wall portion in the axial direction.
