1. A rotary compressor, comprising:
a rotational shaft;
first and second bearings configured to support the rotational shaft in a radial direction;
a cylinder disposed between the first and second bearings to form a compression space;
a rotor disposed in the compression space and coupled to the rotational shaft to compress a refrigerant as the rotor rotates; and
at least one vane slidably inserted into the rotor, the at least one vane coming into contact with an inner peripheral surface of the cylinder to separate the compression space into a plurality of regions, wherein the at least one vane comprises a pin that extends in an axial direction, wherein at least one of the first bearing or the second bearing comprises a rail groove into which the pin is inserted, wherein a distal end surface of the at least one vane comprises a chamfer formed on an edge, the chamfer being a cut-away straight sloping surface, and wherein an angle between the chamfer and a longitudinal virtual line of the at least one vane is 70° to 90°.
