Inverter-integrated electric compressor

An inverter-integrated electric compressor comprising:

• a compressing mechanism portion which sucks, compresses and discharges fluid,
• a motor which drives the compressing mechanism portion,
• a body casing in which the compressing mechanism portion and the motor are incorporated,
• the body casing including a suction cover which covers a side of the compressing mechanism portion,
• an inverter case in which an inverter for driving the motor is incorporated,
• a suction passage for refrigerant is formed in an internal hermetic space between the suction cover and the compressing mechanism portion, and
• the suction cover includes a suction passage-forming surface which covers the suction passage and a peripheral wall which provides a suction pipe mounting portion connected to the suction passage,
• wherein the suction cover has a first surface opposed to the suction passage-forming surface, the suction passage-forming surface is cooled by a refrigerant flowing through the suction passage,
• at least the inverter case is in close contact with the first surface and the inverter case is fixed to the first surface, and
• the inverter case is rotatably and slidably disposed on the first surface before being fixed to the body casing, and the compressor is adapted for the inverter case to be fixed to the body casing at one position selected from multiple positions on the first surface.
