Claim:
A sealing structure comprising: a head component having an ejection port configured and arranged to eject compressed refrigerant, the head component including a main body having a bearing hole configured and arranged to have an axial member inserted therein, 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; and a muffler component disposed so that a muffler space is formed between the muffler component and the head component, the muffler component having an opening configured and arranged to have the axial member inserted therein, with a peripheral portion of the opening entirely contacting an end surface of the boss portion, and the muffler component being fastened to an end surface of the annular side wall so that contact between the boss portion and the muffler component causes the muffler component to be warped to protrude away from the main body and remain in contact with the boss portion.
