A rotary compressor is provided to prevent the performance deterioration of a plug by setting a gap between a cylinder and a sealed casing smaller than the distance between an O-ring and a sealed casing side end of the plug. A rotary compressor(10) comprises a sealed casing(12) which includes a motor(14) and first and second rotating compression elements(32,34), cylinders(38,40), support members(54,56), discharge noise chambers(62,64) formed on the support members respectively, and covers(66,68) installed on the support members respectively. Gas compressed by the first rotating compression element is discharged into the sealed casing and the discharged gas having intermediate pressure is compressed in the second rotating compression element. The support member closes an opening of the cylinder and has a shaft support. The discharge noise chambers are in communication with the inside of the cylinder. The cover closes an opening of the discharge noise chamber. The cylinder, the support member and the cover are coupled to each other through a main bolt(129). The cylinder and the support member are coupled to each other through an auxiliary bolt. |
