摘要： PROBLEM TO BE SOLVED: To easily and electrically connect a dynamo-electric machine and an inverter by a simple structure in a driving device for vehicle. SOLUTION: A first case 52 houses a first MG 14. A second case 54 is connected to the first case 52, and houses a second MG 16 and the inverter 30 integrally fitted on the outer peripheral side of the second MG 16. The side face 31 of the inverter 30 and the first case 52 are formed in a superposedly in the radial direction. Consequently, a conductor can be disposed directly in the first case 52 without passing the outside from the side face 31 of the inverter 30. Accordingly, even when cases housing the first motor 14 and the inverter 30 differ, they can easily be connected electrically. COPYRIGHT: (C)2010,JPO&INPIT
