Abstract
A filling nozzle provided with a filling cylinder, an air-injection cylinder, and an air-supply unit. The filling cylinder is configured such that an auger rotates about the axis thereof to discharge powder through an opening provided at the lower end of the filling cylinder. The air-injection cylinder is fitted to the exterior of the filling cylinder to form an annular space between the filling cylinder and the air-injection cylinder. The air-supply unit supplies air in the annular space. A tip portion of the air-injection cylinder extends downward below the opening and has an air-discharge mouth formed in a tapered shape such that the tip portion has a diameter smaller than that of the opening.
