PURPOSE: To provide a highly reliable rotary compressor to prevent abnormal abrasion of a roller and a vane by using polyalkyleneglycol as lubricating oil or polyalphaolefine as base oil for the compressor using carbon dioxide as a natural refrigerant for the refrigerant. CONSTITUTION: The vane whose radius of curvature (Rv) (cm) at a sliding part with the roller of the vane is expressed by a following expression 1 is used in the rotary compressor using carbon dioxide gas as the refrigerant and using polyalkyleneglycol (to be used as a formal name) or polyalphaolefine (to be used as a formal name), as the lubricating oil or mineral oil as the base oil. T<Rv<Rr expression 1 (In the expression 1, T expresses thickness (cm) of the vane and Rr expresses an outer peripheral curvature radius (cm) of the roller sliding on the vane.). 본 발명은 냉매로 자연냉매로서의 이산화탄소를 사용한 압축기에 윤활유로써 폴리알킬렌글리콜 또는 폴리알파올레핀을 베이스 오일로 포함하는 것을 이용하여, 롤러와 베인의 비정상적인 마모를 방지하여, 신뢰성 높은 회전압축기를 제공한다. 탄산가스를 냉매로 사용하고, 윤활유로서는 폴리알킬렌글리콜, 폴리알파올레핀 또는 광유를 베이스 오일로 포함하는 것을 이용한 본 발명에 의한 회전압축기에 있어서, 베인과 롤러와의 미끄럼 접합부의 곡률 반경(Rv)(cm)은 다음 식(1)로 나타난다. T＜Rv＜Rr식(1) 　[단, 식(1)중, T는 베인의 두께(cm), Rr은 베인과 미끄럼 접합하는 롤러의 외주곡률반경(cm)을 나타낸다.］
