PROBLEM TO BE SOLVED: To improve abrasion resistance between two sliding surfaces. SOLUTION: This compressor has a plurality of mutually sliding components, hardness of the sliding component 33 with high sliding density which has smaller total area impressed by load between two sliding surfaces is set higher than the hardness of the sliding component 19 with low sliding density, surface roughness of the component 33 with high sliding density is set lower than that the sliding component 19 with low sliding density, and therefore abrasion amount of one sliding component is prevented to extremely increase.
