PROBLEM TO BE SOLVED: To lower the occurrence of the leak of a refrigerant in a compressor even if a high-pressure refrigerant is used by strictly performing an air-tight test in a compressor manufacturing step. SOLUTION: In this compressor 10, first and second rotating compression elements 32 and 34 driven by an electric element 14 are installed, as a driving element, in a closed container 13. The CO<SB>2</SB>refrigerant sucked from a refrigerant inlet tube 94 is compressed by the first rotating compression element 32 and discharged to the inside of the closed container 12 and discharged to the outside of the closed container through a refrigerant discharge tube 96. A flange part 98A for engagement with a tube connection coupler 171 is formed on the outer periphery of a refrigerant discharge tube 98 which is one of a plurality of tubes arranged continuously with each other in the closed container 12. The tips of a refrigerant inlet tube 92, a refrigerant inlet tube 94, and the refrigerant discharge tube 96 other than the refrigerant discharge tube 98 are pinched. COPYRIGHT: (C)2005,JPO&NCIPI
