PROBLEM TO BE SOLVED: To cool a motor-generator internally while down-sizing an apparatus by disposing a motor-generator between a clutch and a transmission mechanism.SOLUTION: A crank shaft 3 of an engine E is connected to an input member 4A of a clutch 4; an output member 4B of the clutch 4 is connected to a drive shaft 6 of a transmission mechanism 5; a rotor 9 of a motor-generator 8 is connected to the drive shaft 6 between a drive member 7 of the transmission mechanism 5 and the output member 4B of the clutch 4. An air introduction port 26 is formed in a clutch casing 4a of the clutch 4, and a motor case 8a to which a stator 10 of the motor generator 8 is attached is fixed onto the clutch casing 4a, to form a cooling air path 14 from the clutch casing 4a to a casing 5A of the transmission mechanism 5 through the motor-generator 8. |
