PROBLEM TO BE SOLVED: To provide a blower device in which it is difficult for water to enter into a blower motor 30.SOLUTION: A blower device comprises a ring-like cover 3 mounted to a motor holder 1 around an opening 2 and covering a motor upper part 30a, and a blower fan 5 whose rotation center part of coupled with a rotation shaft and whose lower end is adjacent to the motor holder 1. The ring-like cover 3 comprises a sleeve part 3s around which plural uneven parts 6 are formed and that covers the motor upper part 30a, a flange part 3f continued from a lower end of the sleeve part 3s and covering a surface of the motor holder 1, and an annular skirt part 3w formed at a peripheral edge of the flange part 3f. The annular skirt part 3w is press-fitted in an annular groove part 1m of the motor holder 1. 【課題】水がブロワモータ３０内に浸入し難いブロワ装置を提供する。【解決手段】ブロワ装置は、開口部２の周りのモータホルダ１に取りつけられモータ上部３０ａを覆うリング状カバー３と、回転軸に回転中心部が結合され下端部がモータホルダ１に接近するブロワファン５とを備えている。リング状カバー３は、周囲に複数の凹凸部６が形成されモータ上部３０ａを覆うスリーブ部３ｓと、スリーブ部３ｓの下端から連続してモータホルダ１の表面を覆うフランジ部３ｆと、フランジ部３ｆの周縁に形成された環状のスカート部３ｗとを備える。環状のスカート部３ｗは、モータホルダ１の環状溝部１ｍの中に圧入されている。【選択図】図１
