A rotary compressor includes a cylinder (21, 31) having annular cylinder space (C1), and a piston (22, 32) arranged to be eccentric to the cylinder (21,31), and a drive shaft (53) connected to the piston (22, 32), the piston (22, 32) having a piston portion (22a, 22b) which eccentrically rotates relative to the cylinder (21, 31), and a piston end plate (22c, 32c) which closes the cylinder space (C1), wherein the cylinder (21, 31) has end plate storage space for storing the piston end plate (22c, 32c) in an eccentrically rotatable manner, the cylinder space (C1) constitutes a main cylinder chamber, and the end plate storage space constitutes a sub-cylinder chamber (C2) to provide an eccentrically rotatable compression mechanism (20, 30) including a plurality of cylinder chambers (23a, ..., 23d, 33a, ..., 33d) without increasing costs and complicating its configuration. |
