A discharge pipe part(30) discharges the air provided with the intake pipe part to outside. A mouth part(40) is connected between the intake and the discharge pipe part to feed air to the diver. An air drive part(50) compulsorily supplies the air of the intake pipe part. A controller(60) controls the air drive part according to the water pressure.
