PROBLEM TO BE SOLVED: To provide a high reliable rotary compressor such that the abnormal wear of the roller and vane is prevented, even if the polyolester is used as the refrigerant not including chlorine in a molecule and the lubricant or the polyvinyl ether as the base oil. SOLUTION: This rotary compressor uses such a vane that the curvature radius (Rv) (cm) in the slide contact part with a roller of the vane is shown in the following formula (1). T<Rv<Rr is formula (1). In this formula (1), T shows the thickness (cm) of the vane and Rr shows the circumference curvature radius (cm) of the roller that slide-contacts the vane.
