A propeller is integrally attached to the outer periphery of a rotor that faces the inner diameter through a gap and is rotatably supported by a bearing provided on the stator support, and a propeller hub that is fixed to one end surface of the rotor. In the axial flow fan disposed in the cylindrical ventilation passage, the propeller hub has a structure in which a metal plate having a diameter larger than the end face of the rotor is brought into contact with and fixed to the end face of the rotor, and is provided on the end face of the propeller hub. Features of axial flow fan.
