Abstract
A compressor includes a cylinder, a shaft including a main shaft and an eccentric part, a roller part having an inner circumferential surface fitted on an outer circumferential surface of the eccentric part so as to make an orbital motion, a blade part along with the roller part partitioning inside of the cylinder chamber into low and high pressure chambers, and sliding bearing parts fixed to the cylinder and including cylindrical surfaces supporting the main shaft. A relation (φDs−φDr)/2<ε is satisfied. φDs is an inside diameter of the inner circumferential surface of the cylinder chamber, φDr is an outside diameter of the outer circumferential surface of the roller part, and ε is an eccentricity of a central axis of the eccentric part relative to a central axis of the main shaft. Central axes of the cylindrical surfaces are eccentric relative to a central axis of the inner circumferential surface.
