There is provided a rotary compressor capable of preventing deterioration of performance following plug fixing carried out to prevent falling-off of a spring member. The rotary compressor comprises a cylinder constituting a rotary compression element, a roller 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 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 positioned in the hermetically sealed container side of the spring member, and inserted into the housing portion to fit into a gap, and an O ring 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.

What is claimed is: 1. A rotary compressor comprising: an electric element, and first and second rotary compression elements driven by the electric element, both components being provided in a hermetically sealed container, gas compressed by the first rotary compression element being discharged into the hermetically sealed container, and the discharged gas of intermediate pressure being further compressed by the second rotary compression element; first and second cylinders respectively constituting the first and second rotary compression elements; a first support member adapted to seal an opening surface of the first cylinder, and provided with a bearing of a rotary shaft of the electric element; a second support member adapted to seal an opening surface of the second cylinder, and provided with a bearing of the rotary shaft; and a carbon bush provided between one of the bearings of the first and second support members and the rotary shaft; wherein the bush is provided in the bearing of the second support member, wherein the compressor includes an oil reservoir, the first support member is adjacent to the oil reservoir, and no bushing is on the first support member.
