Abstract
A rotary compressor includes a cylinder having an annular cylinder space, a piston eccentrically disposed relative to the cylinder, and a drive shaft (53) connected to the piston. The piston has a piston portion eccentrically rotatable relative to the cylinder, and a piston end plate closing the cylinder space. The cylinder has an end plate storage space storing the piston end plate in an eccentrically rotatable manner. The cylinder space forms a main cylinder chamber, and the end plate storage space forms a sub-cylinder chamber.
