Abstract: A multi-cylinder rotary compressor includes plural compression mechanism parts. A drawing force is applied to a vane of at least one of the compression mechanism parts radially outward with respect to a drive shaft, making a pressing force pressing the vane toward a piston smaller than in other compression mechanism parts. In a normal state, a pressing force due to a gas pressure difference between a suction pressure and a discharge pressure is larger than the drawing force, and a vane front end is pressed against a rotary piston peripheral wall. When the drawing force becomes greater than the pressing force, the vane front end is moved to separate from the rotary piston peripheral wall with a space through which oil is introduced from a sealed container, and a retention mechanism retains the vane separated from the piston, and the compression mechanism part switches to an uncompressed state.
