PROBLEM TO BE SOLVED: To provide a rotary compressor with a plurality of cylinder structures for changing the compression capacity thereof without using another inverter circuit and a control board. SOLUTION: The rotary compressor comprises the plurality of cylinders, a rotary shaft having a plurality of eccentric portions for eccentric rotation in compression chambers formed in the cylinders, a plurality of roller pistons rotatably connected to the eccentric portions for compressing a cooling medium in the compression chambers, a positive/reverse rotating motor for selectively positive/reverse rotating the rotary shaft, and a clutch for changing over the roller pistons so that the compression capacity of the compressor is changed depending on the rotating direction of the rotary shaft with the compressing or idling operation of the roller pistons depending on the rotating direction of the rotary shaft.
