ABSTRACT:
An impeller includes a vane component integrally molded with a plurality of vanes having predetermined tilt angles that change continuously from a central portion of rotation, and a bottomed cylindrical component formed with a rotating shaft body, so that the vanes have an ideal shape with tilt angles that match the rotational peripheral velocity. For this purpose, the impeller of an axial fan serves as a rotor arranged to be rotatable with respect to a stator fixed to a main body of the axial fan. The impeller includes a bottomed cylindrical component formed by injection molding from a predetermined resin material such that a shaft body axially supported by a rotary bearing of the main body is formed at a central portion of rotation thereof, and a vane component formed by injection molding from a predetermined resin material such that a plurality of vanes are equidistantly formed thereon.
