PROBLEM TO BE SOLVED: To solve the problem wherein a large amount of oil is supplied to a bearing since an amount of oil supplied to the bearing is hardly controlled in a conventional compressor and it causes performance degradition of a refrigerating cycle such as lowering of heat exchange efficiency in a heat exchanger when the oil flows into the refrigerating cycle together with a coolant gas discharged from a compression mechanism section. SOLUTION: An amount of the oil discharged from an upper end of the bearing is reduced because an oil groove 14 arranged at a bearing section of a bore diameter of a main end plate is not continued on an upper end section A of the bearing.
