Claims

[Claims for Utility Model Registration] (1) A cylinder, a piston rotatably disposed within the cylinder, a side plate closing both ends of the cylinder, and a bolt on the side plate on the discharge side, in a sealed container. 1. A rotary compressor having a discharge muffler fixed by a rotary compressor, wherein a central opening of the discharge muffler is pressed and supported by an inner diameter surface of a bearing boss of a side plate on the discharge side. (2) The rotary compressor according to claim 1, wherein the discharge muffler is press-supported near the end of the inner diameter surface of the bearing boss via an O-ring. (3) The rotary compressor according to claim 1, wherein the discharge muffler is pressed and supported by a large inner diameter portion on the terminal end side from the rear portion provided near the terminal end on the inner diameter surface of the bearing boss.
