A rotary compressor which uses carbonic acid gas as the refrigerant, polyalkylene glycol as a lubricant, or polyalfa olefin or mineral oil as a base oil. The compressor includes a roller and a vane whose radius of curvature (Rv) (cm) at a sliding contact portion with respect to said roller can be represented by the following Expression (1): <DF NUM="Expression (1)">T < Rv < Rr </DF> where T is the thickness (cm) of the vane, and Rr is the radius of curvature (cm) of the outer periphery of the roller which slidingly comes into contact with the vane. <IMAGE> |
