PROBLEM TO BE SOLVED: To provide a sealing structure by a seal material that is hardly deteriorated without being hardened even when a chlorofluorocarbon refrigerant of a low warming coefficient is used. SOLUTION: This is the sealing structure in which the seal material 51 is arranged at the joined portion of a cylinder block 2 and a rear housing 6 where the chlorofluorocarbon refrigerant is circulated. The seal material 51 is made of fluorine-based or silicone-based rubber of the Shore hardness of 65-80. In addition, the seal material 51 contains carbon of 50-180 parts by weight to the fluorine-based or the silicone-based rubber of 100 parts by weight. COPYRIGHT: (C)2009,JPO&INPIT
