PROBLEM TO BE SOLVED: To suppress the occurrence of noises by reducing vibration propagating to a fan body, when pressing the output shaft of a motor, formed as a round bar, into a cylindrical rotation preventive member having higher mechanical strength than the fan body.SOLUTION: A fan includes a cylindrical rotation preventive member 26 to be rotated integrally with the fan body. The rotation preventive member 26 is formed by molding a resin having higher mechanical strength than a resin for the fan body. An output shaft 13a formed as the round bar is pressed into the rotation preventive member 26. Between the rotation preventive member 26 and a center cylinder part 28, a clearance S is formed.

    【課題】モーターの出力軸を丸棒としてファン本体よりも機械的強度の高い筒状の回転防止部材に圧入する場合に、ファン本体に伝播する振動を低減して異音の発生を抑制する。【解決手段】ファンは、ファン本体と一体に回転する筒状の回転防止部材26を備えている。回転防止部材26はファン本体を構成する樹脂よりも機械的強度の高い樹脂を成形してなる。出力軸13aは丸棒からなり、回転防止部材26に圧入されている。回転防止部材26と中心筒部28との間には、隙間Sが形成されている。【選択図】図7
