Abstract: A rotary compressor may include a rotary shaft; a plurality of plates that supports the rotary shaft; a cylinder provided between the plurality of plates to define a compression space, and provided with a vane slot; a roller slidably coupled to the rotary shaft inside of the cylinder, and having a hinge groove on an outer circumferential surface thereof; and a vane, a first end of which is slidably coupled to the vane slot of the cylinder, and a second end of which is rotatably coupled to the hinge groove of the roller. At least one of first and second axial end surfaces of the roller facing the plurality of plates is provided with a dimple portion having a predetermined depth. With this structure, contact surfaces between the roller and the plate may be prevented from being in close contact with each other, preventing the roller or the plate from being damaged or a performance of the compressor from deteriorating due to friction loss, thereby improving reliability and performance of the compressor.
