Abstract

A sealing structure of compressor that can prevent the occurrence of "biting" of a rectangular cross-section sealing member is disclosed. The sealing structure comprises a front housing, terminal surface of a housing, and a sealing member disposed in a circular groove having substantially a rectangular cross-section. By providing a space for absorbing the deformation of the sealing member formed when the front housing is mounted on the housing, the "biting" of the deformation of the sealing member between the front housing and the housing can be effectively eliminated:
