To provide a blower 1 which is configured to capture abrasion powder in a satisfactory manner.SOLUTION: In a blower 1, a flange 20 supports an electric motor 10 from the outside in a radial direction around a rotary shaft 11. An impeller 30 is disposed on one side in an axial direction with respect to the electric motor 10 and the flange 20, and rotates with the rotary shaft 11 in order to generate an air stream. Between the electric motor 10 and the flange 20, and the impeller 30, an air flow passage 40 is formed for circulating cooling air having passed through inside a motor case to the outside in the radial direction. The flange 20 and the impeller 30 form the air flow passage 40 like a labyrinth, in order to constitute a labyrinth structure for capturing abrasion powder produced by friction between a commutator 15 and brushes 16a and 16b.SELECTED DRAWING: Figure 1

    【課題】摩耗粉を良好に捕獲するようにした送風装置1を提供する。【解決手段】送風装置1は、フランジ20は、回転軸11を中心とする径方向外側から電動モータ10を支える。羽根車30は、電動モータ10とフランジ20とに対して軸線方向の一方側に配置されて、回転軸11とともに回転して空気流を発生する。電動モータ10およびフランジ20と羽根車30との間には、モータケース内を通過した冷却風を径方向外側に流通させる空気流路40が形成されている。フランジ20と羽根車30とは、空気流路40を迷路状に形成して、整流子15とブラシ16a、16bとの摩擦によって生じる摩耗紛を捕捉するラビリンス構造を構成する。【選択図】図1
