Abstract
A fan apparatus for a cooking device is provided having a fan impeller that is held on a drive shaft of a rotary drive by its hub and is pressed against a stop of the drive shaft in an axial direction by a screw nut. In order to ensure that the fan impeller is securely held on the drive shaft, the screw nut exerts a pressing force on the fan impeller in a radial direction.
