PURPOSE:To facilitate the removal of oil adhered by a structure wherein component members of a ventilating fan are molded in synthetic resin mixed with fluoroplastic. CONSTITUTION:A spinner 2, blades 3, a front panel 5, an oil reservoir 6, a smoke collecting hood 7 and a shutter 8 are molded in synthetic resin A, which molds various forms at low temperature, such as ABS resin, polypropylene resin or the like. The synthetic resin A to form each component member of a ventilating fan is mixed with particles of fluoroplastic F, which is non-adherent resin. Because the melting temperature of fluoroplastic F is higher than that of the synthetic resin A, both the resins do not mix with each other into one integral body. By molding the component members of the ventilating fan in such a manner as mentioned above, the molding of the members is facilitated and the members, the oily matters adhered onto which are easily removed, are obtained.
