Abstract: The present invention provides a hermetic or open compressor for hydrocarbon refrigerant having high reliability. According to the present invention, in the compressor using hydrocarbon as refrigerant, synthetic oil such as polyalkylene glycol oil, ester oil or ether oil is used as freezer oil. Sliding member of the compressor includes both a portion made of aluminum material and a portion made of iron material. Therefore, it is possible to realize a compressor having excellent wear resistance and high reliability.
