<p>A sealing structure, which is between a rear head 38 having an ejection port ejecting compressed refrigerant and a rear muffler 39 which is disposed so that a muffler space A2 is formed between the rear muffler 39 and the rear head 38, is arranged so that, the rear head 38 includes a main body 38b having a bearing hole 38a into which a shaft is inserted, an annular boss portion 38c protruding from the main body 38b while circumscribing the bearing hole 38a, and an annular side wall 38d protruding from the main body 38b while circumscribing the boss portion 38c. The rear muffler 39 has an opening 39b into which the shaft is inserted and is fastened to the end surface of the side wall 38d so that the peripheral portion 39c of the opening 39b contacts the end surface of the boss portion 38c, and the end surface 38g of the boss portion 38c has a part which is entirely further from the main body 38b than the end surface 38h of the side wall 38d.</p> |
