Abstract: PURPOSE:To reduce the leakage of refrigerant through weak fastening force by providing a cylinder with a suction lead and a contacting part between a gasket and a head attached through a discharge lead and the gasket with a closed loop projecting part. CONSTITUTION:In a closed electric compressor, a head 6 is fastened to a cylinder 1 by a bolt 7 through a suction lead 2, a plate 3 attached to the side opposite to the cylinder of the suction lead 2, a discharge lead 4 and a gasket 5. In this case, a head 10 is provided with a closed loop-shaped projecting part 11, by which the suction plenum 10a and discharge plenum 10b of the head 10 are severally covered. Thus even when the bolt 7 is fastened by weak force, the projecting part 11 of the head 10 eats into the gasket 5 to reduce the leakage of refrigerant between the head 10 and the gasket 5.
