Zusammenfassung:Provided is a reversible fan including: a fin configured to produce a current of air in both of a normal direction and a reverse direction; an impeller configured to be rotatable about a rotation axis; a motor configured to rotate the impeller; and a tubular frame housing the impeller and the motor, wherein the fin has a shape that allows producing louder noise upon producing the current of air in the normal direction than upon producing the current of air in the reverse direction, and protrudes inward in a radial direction from an inner peripheral surface of the frame.
