A rotary feeder configured to rotate the rotor while pushing the blades fitted in the slide grooves outward by the elastic force of the springs while pressing the tips of the blades against the inner wall surface of the rotor chamber. The disc-shaped side plates are attached to both ends of the rotor so as to close the end faces of the slide grooves of the vane plates, and the space between the disc-shaped side plates on both sides and the inner wall surfaces of both ends of the rotor chamber is controlled by high pressure air. In addition to being a high pressure air chamber for injecting air into the high pressure air chamber, the tip side seal part is pressed against the inner wall surface of the rotor chamber when assembled into the casing on the outer peripheral surface of each of the disc-shaped side plates, and is bent outward in the direction of the rotor. It is in the state of Injection of high pressure air to the air chamber, a rotary full Ida, characterized in that attaching the flexible seal member configured to contact the respective distal sealing portion of the above inner wall surface of each rotor chamber at that pressure.
