きを設けたことを特徴とする回転式圧縮機。、A piston that eccentrically rotates inside the cylinder by a crankshaft, a vane that touches the outer periphery of the piston and slides in a groove formed inside the cylinder by the rotation of a screw, and a vane that contacts both end surfaces of the cylinder. The cylinder chamber formed by the bearing and the end bearing is divided into a high-pressure chamber and a low-pressure chamber by the vane and compressed, and the high-pressure gas is discharged through the discharge hole provided in the main bearing or the end bearing. In a rotary compressor in which a compression element to be discharged is housed in a closed container serving as a high-pressure space, a cutout having a projected shape of a track shape, a circle, a rectangle, etc. cut in half is provided on the compression chamber side of the discharge hole. A rotary compressor characterized by the following: ,
