Abstract

A sealing is arranged between a rear head having an ejection port configured and arranged to eject compressed refrigerant and a rear muffler disposed so that a muffler space is formed between the rear muffler and the rear head. The rear head includes a main body having a bearing hole, an annular boss portion protruding from the main body and circumscribing the bearing hole, and an annular side wall protruding from the main body and circumscribing the boss portion. The rear muffler has an opening and is fastened to the end surface of the side wall so that the peripheral portion of the opening contacts the end surface of the boss portion. Preferably, the end surface of the boss portion has a part entirely further from the main body than the end surface of the side wall.
