[Problem to be solved] Provided is a rotary compressor which can make a capacity by which the rotary compressor is pushed larger while preventing a property between a high pressure side space and a low pressure side space in a cylinder chamber from deteriorating. [Solution] A rotary compressor (100) includes a piston (20) attached to an eccentric portion (4c) of a crank shaft (4) to be slid, a cylinder (7) having a cylindrical cylinder chamber and in which the eccentric portion (4c) and the piston (20) are disposed in the cylinder chamber, and a compression mechanism having a vein (9) dividing the cylinder chamber into a low pressure space and a high pressure space. The piston (20) includes an inner piston (21) provided on an outer peripheral surface of the eccentric portion (4c) to be slid freely and an outer piston (22) provided on an outer surface of the inner piston (21), and the inner piston (21) is divided into a plurality of arc-shaped members (21a) cut to have a cross-section along the center axis of the eccentric portion (4c). |
