Abstract

　舌部と羽根車との干渉による周期音を含む騒音の発生を抑制することができる遠心式送風機を提供する。回転軸周りに複数枚の翼が設けられた羽根車（２）と、羽根車（２）を収納するとともに、回転軸の軸線方向の一端側に吸い込み部を有するケーシング（３）と、ケーシング（３）内における羽根車（２）の周囲に配置された渦巻状流路（４）と、渦巻状流路（４）における巻き終わりから巻き始めへの空気の流入を抑制する舌部（６）と、が設けられ、舌部（６）における羽根車（２）の回転方向と逆回転方向側の先端には、羽根車（２）の径方向において羽根車（２）との間の隙間を略一定に保ちつつ、軸線方向の位置に応じて逆回転方向へ突出する量が変化する延長部（２０）が設けられていることを特徴とする。
