PROBLEM TO BE SOLVED: To constitute car apparatuses such as an air conditioner, an oil pump, etc., simply and cheaply which require motive power, by driving the car apparatuses requiring motive power by electric motors. SOLUTION: An oil pump 50 of a gear type, etc., is provided in a first chamber 22, and by rotating it by a rotor shaft 36 of a motor-generator 14 operating oil is supplied to a hydraulic actuator to be linked to a first and a second clutches 34, 40 of an epicyclic gear device 18, and a hydraulic actuator to be linked to a hydraulic clutch of an automatic transmission 16, and a hydraulic brake. To the oil pump 50, a rectifier circuit composed by combining four check valves into a bridge is connected, and operating oil is pumped up from a oil reservoir 54 provided in the lower part of a housing 20 regardless of the direction of rotation of the motor-generator 14, and is fed out into oil supplying routes formed in a partition 20a and the housing 20 and so on. |
