A rotary compressor according to the present invention, the rotary shaft; A plurality of plates supporting the rotating shaft; A cylinder provided between the plurality of plates to form a compression space and provided with a vane slot; A roller that is slidably coupled to the rotation shaft and provided inside the cylinder, and has a hinge groove formed on an outer circumferential surface thereof; And one end is slidably coupled to the vane slot of the cylinder, the other end is a vane rotatably coupled to the hinge groove of the roller; Including, at least any one of the axial end faces of the roller facing the plurality of plates A wear avoidance portion having a predetermined depth may be formed on one end surface. Through this, it is possible to prevent excessive contact between the roller and the plate from being in close contact with each other, thereby suppressing degradation of the compressor due to damage to the roller or plate or friction loss, thereby improving the reliability and performance of the compressor.
