PROBLEM TO BE SOLVED: To make a heat from a motor hard to transfer to an inverter circuit through a power line to contain the motor and the inverter circuit in one housing. SOLUTION: A cooling fin 37 is arranged, for example, at the outside between the power lines 36 for AC three-phases, and the heat of the power line 36 is emitted outside from this cooling fin 37. More particularly, the connector of an inverter power line member 29 and a motor power line member 30 is covered by a lid member 8, and in the state that the lid member 8 is removed, the connecting work of the power line member is performed. The cooling fin 37 is projected in the rear surface of the lid member 8. After the power line connecting work is ended, when the opening of the housing 3 is covered with the lid member 8 and the lid member 8 is mounted in the housing 3, the cooling fins 37 are arranged between the power lines 36 and at the outside. It is as good also for the front surface of the lid member 8 as provided in the cooling fin 41. COPYRIGHT: (C)2006,JPO&NCIPI
