PROBLEM TO BE SOLVED: To provide a rotary compressor capable of preventing abnormal wear of a roller and a vane even when using polyol ester as refrigerant free from chlorine in molecule and lubricant and polyvinyl ether as base oil and having high reliability. SOLUTION: Such vane that radius of curvature (Rv) (cm) in a slide-contact part of the vane and the roller is expressed by the following expression (1) is used. T<Rv<Rr (1), wherein T denotes thickness (cm) of the vane, and Rr denotes radius of outer periphery curvature (cm) of the roller coming into slide-contact with the vane. COPYRIGHT: (C)2005,JPO&NCIPI
