Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a rotation fan, etc., in which the deformation or destruction of the rotation fan can be prevented even when operating the rotation fan of an electric fan mounted in a vacuum cleaner, etc., at a high speed. SOLUTION: A claw 11 for caulking at the outermost part of a fan aerofoil 1 is set near the outermost side of the fan aerofoil 1. One and the other side plates 2 and 3 are made up to the rotation fan extended from the outermost of the fan aerofoil 1 in parallel in the peripheral direction. Even when operating the rotation fan 10 at high speed, centrifugal force of the part extended from the claw 11 for caulking at the outermost of the fan aerofoil 1 in the peripheral direction can be suppressed, and the deformation or the destruction of the rotation fan 10 can be made difficult to occur when operating the rotation fan 10 at the high speed.
