A variable-displacement rotary compressor comprises a rotor with a vane and a side plate disposed to abut a side face of the rotor. The side plate has a suction port formed therein to open to both a working chamber abutment face thereof abutting to the rotor side face and a low pressure chamber, and the rotor has a suction path formed therein to open to the working chamber and to an abutment surface of the rotor. The suction path of the rotor communicates with the suction port of the side plate through rotation of the rotor so that a fluid is sucked from the low pressure chamber into the working chamber under suction stroke through the suction path and the suction port.
