PROBLEM TO BE SOLVED: To provide a rotary compressor with small input loss, by reducing a sliding loss generated by a reciprocating motion of a vane in a vane groove. SOLUTION: The rotary compressor includes: a cylinder 5 having a cylinder chamber; a piston 9 oscillating in the cylinder chamber; the vane 11 partitioning the inside of the cylinder chamber into a suction chamber and a compression chamber; and the vane groove 10 which is formed to the cylinder 5 and in which the vane 11 reciprocates. At least a part of a tip part of the vane 11 is in a circular shape having a diameter larger than a thickness of the vane 11, and is fitted and connected to be capable of oscillating to a fitting part 9A formed to the piston 9. In this case, cutouts 11c, 11d are formed to a side face of the vane 11 facing the suction chamber and a side face thereof facing the compression chamber so as to prevent contact of a circular curved face of the fitting part formed to the piston 9 and a flat face or a curved face to which an outer peripheral face of the piston 9 is connected when the piston 9 oscillates in the cylinder chamber.
