する欠点がある。Detailed Description of the Invention (a) Industrial Application The present invention relates to a hermetic rotary compressor in which a sliding vane is pressed against the outer periphery of a rotating roller in a cylinder. In the conventional hermetic rotary compressor, which was compared with Japanese Patent Application Laid-Open No. 58-18590, which precedes the invention, the rotating roller is made of an aluminum base alloy for the purpose of reducing its weight, and an iron base alloy with a high specific gravity is used. is formed only on a part of the surface of the rotating roller, the aluminum base alloy is exposed at the outer periphery of the rotating roller and wears out between it and the sliding vane, causing damage at this worn location. There is a drawback that refrigerant gas leaks from the discharge side of the cylinder chamber to the suction side, resulting in a decrease in compression efficiency.
