Zusammenfassung:A scroll compressor is disclosed. The scroll compressor may include an oil supply hole penetrating from an oil passage to an outer circumferential surface of a rotating shaft, and an oil supply groove communicating with the oil supply hole and formed along the outer circumferential surface of the rotating shaft. The oil supply groove may be provided in plurality axially spaced apart by a preset distance. This can prevent the oil supply groove from invading an oil film section and increase centrifugal force against oil in the oil supply groove, thereby suppressing friction loss and wear between a main frame and the rotating shaft.
