Patent ID: 8152490

Claim:
A motor-driven compressor comprising: a compression mechanism compressing a refrigerant gas; a rotary shaft rotating to drive the compression mechanism; an electric motor connected to the rotary shaft; a motor drive circuit for driving the electric motor; and a housing assembly in which the compression mechanism, the electric motor and the motor drive circuit are disposed along the axial direction of the rotary shaft, the housing assembly having: a first housing for mounting the electric motor and the compression mechanism, the first housing having first and second mounting lugs formed integrally with the peripheral surface of the first housing; and a second housing joined to the first housing for accommodating the motor drive circuit, the second housing having a third mounting lug formed integrally with the second housing, wherein the first through third mounting lugs are fastenable to a mounting object on which the motor-driven compressor is to be mounted by means of fastening members, the first and second mounting lugs are located between the electric motor and the compression mechanism in the axial direction of the peripheral surface of the first housing, and the first and second mounting lugs are formed integrally with the first housing at positions of the first housing where the first and second mounting lugs are not lapped over the electric motor and the compression mechanism.
