ABSTRACT:
An output shaft of a rotating electrical machine and a drive device input shaft are disposed at different shaft center positions. A first gear meshing with a second gear provided on the output shaft of the rotating electrical machine for reducing rotation and transmitting the reduced rotation to a transmission input shaft is provided coaxially with the drive device input shaft, and at least a part of the clutch is disposed at an inner-diameter-side position so as to overlap a gear portion of the first gear in an axial direction.
