回転式圧縮機。(1) A piston that is fitted into the eccentric part of the crankshaft and rotates eccentrically within the cylinder as the crankshaft rotates, one end of which touches the outer periphery of the piston, and the vane groove provided in the cylinder is rotated by the rotation of the bistoy. A closed container is used as a high-pressure container, which is equipped with a vane that reciprocates in the radial direction, a main bearing and an end bearing that close both end surfaces of the cylinder to form a cylinder chamber, and houses a compression device that compresses the gas in the cylinder. In the rotary compressor used, an annular groove is provided on the end surface of the piston facing the main bearing and the end bearing, and a ring is attached to the outer diameter side wall of the groove by its own tension or fitted with an appropriate gap. A rotary compressor characterized by the following: （２）内径のピストン端面側角部に適当き大きさ面トリ
