1. A rotary compressor, comprising:
at least one cylinder formed in an annular shape;
a plurality of bearing plates disposed, respectively, at both sides of the at least one cylinder in an axial direction;
at least one roller disposed in the at least one cylinder; and
at least one vane slidably inserted into the at least one cylinder and configured to be slidable into contact with an outer circumferential surface of the at least one roller, wherein the at least one cylinder comprises:
a vane slot having an inner circumferential surface open so that the vane is slidably inserted therein;
a suction port having an inner circumferential surface open and disposed at one side of the vane slot in a circumferential direction; and
a partition wall disposed between the vane slot and the suction port to partition the vane slot and the suction port from each other, and wherein the partition wall comprises at least one elastic portion recessed by a predetermined depth in the circumferential direction into an inner surface of the suction port defining one of circumferential side surfaces of the partition wall.
