PROBLEM TO BE SOLVED: To provide a reliable compressor by preventing deviation of a shaft center and rattling due to thermal deformation of a resin oil cone. SOLUTION: The oil cone 141 opening under refrigerator oil is provided in a cavity part 130 provided at a main shaft lower end 125 of a crank shaft. The oil cone 141 is pressed and fixed on a main shaft part of the crankshaft in an axial direction by an O ring 150. Holding force by the O-ring 150 always acts on the oil cone 141 to prevent deviation of shaft center and rattling, and oil is stably supplied. COPYRIGHT: (C)2006,JPO&NCIPI
