PROBLEM TO BE SOLVED: To provide a compressor sealing structure capable of securing high sealing performance of a joint part by using a rubber-made seal member even if refrigerant gas having relative high gas permeability in relation to a rubber material is used, and having a simple structure, in a compressor. SOLUTION: O-rings 6, 7 are doubly arranged on joint parts of a front housing 2 for constituting a housing of a compressor and a cylinder block 3. A material (nitrile rubber) excellent in mechanical properties and chemical properties is used for the inner O-ring 6, and a material (butyl rubber) excellent in gas permeating resistance is used for the outer O-ring 7. The O-ring 6 has the large diameter, and the outer O-ring 7 has the small diameter.
