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 of the roller; 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. When an imaginary line passing through an axial center of the rotary shaft and a hinge center of the vane is a first center line, and a radial center line of the vane slot passing through the hinge center of the vane is a second center line, the vane slot is disposed such that the second center line is intersected by a predetermined tilting angle with respect to the first center line. With this structure, a roller reaction force is canceled to suppress an increase in side pressure or side wear between a vane and a vane slot into which the vane is inserted.
