A center distance D1 from a motor shaft (12) connected to an electric motor (3) and a generator shaft (13) connected to a generator (5) to a clutch shaft (15) including a wet multiple disc clutch (14) is set longer than a distance Dm from the axial center of the electric motor (3), that is, the axial center of the motor shaft (12) to the outermost circumference of a housing, which houses the electric motor (3). The wet multiple disc clutch (14) is arranged on the electric motor (3) side of the clutch shaft (15). The wet multiple disc clutch (14) and the electric motor (3) are arranged to overlap each other in the axial direction of the engine shaft (11). A piston (36), which actuates the wet multiple disc clutch (14), is arranged in the outer circumferential section of the housing, which houses the electric motor (3), to overlap the electric motor (3) in the axial direction of the engine shaft (11). |
