Rotary vane compressor with vane holding plug

摘要

There is provided a rotary compressor capable of preventing deterioration of performance following plug (137) fixing carried out to prevent falling-off a spring member (76). The rotary compressor comprises a cylinder constituting a rotary compression element, a roller (46) engaged with an eccentric portion formed in a rotary shaft of an electric element, and eccentrically rotated in the cylinder, a vane abutted on the roller to divide an inside of the cylinder into a low pressure chamber side and a high pressure chamber side, a spring member for always pressing the vane (50) to the roller side, a housing portion of the spring member, formed in the cylinder, and opened to the vane side and a hermetically sealed container side, a plug (137) positioned in the hermetically sealed container (12) side of the spring member, and inserted into the housing portion to fit into a gap, and an O ring (138) attached around the plug to seal a part between the plug and the housing portion. In this case, a space between the cylinder and the hermetically sealed container is set smaller than a distance from the O ring to an end of the plug on the hermetically sealed container side.
