Abstract
A fan casing, webs, and a motor casing are integrally formed of a resin material by injection molding to configure a fan housing. An electrically grounded electromagnetic noise guard and a bearing holder to which an outer race of a ball bearing are electrically connected by an electrically-conducting path member provided in the fan casing by means of insert molding. Thus, the ball bearing may sufficiently be prevented from suffering electric corrosion in an electric fan of which a fan housing is made of an insulating resin.
