Zusammenfassung:	PROBLEM TO BE SOLVED: To inexpensively provide a highly-reliable and long-life hermetic refrigerant compressor using a bearing material having high wear resistance and seizure resistance by preventing wear and seizure of a bearing part even in a state where there is a possibility that lubricating oil is not supplied temporarily with a refrigerant containing no chlorine, such as an HFC system or HC system refrigerant.SOLUTION: In the hermetic refrigerant compressor for a refrigeration cycle, at least one bearing for a rotating shaft and a crank uses a member with a bearing bush press-fitted into a bearing member and the surface then finished, the bearing bush being formed by molding a composite body, in which an alloy sintered layer containing no lead and a self lubricating material are combined with a flat back plate, in a cylindrical shape.
