ELECTRIC BLOWER

To provide an electric blower which achieves downsizing and improvement of the efficiency.SOLUTION: An electric blower includes: a rotary shaft 207 rotatably provided; bearings 212, 212 provided at substantially center of the rotary shaft 207 as seen in an axial direction G; a centrifugal impeller 203 provided at one end of the rotary shaft 207; a rotor core 209 which is provided at the opposite side of the centrifugal impeller 203 across the bearings 212 of the rotary shaft 207; a stator 240 which is disposed facing a periphery of the rotor core 209; and a ring member 213 provided at the other end of the rotary shaft 207. The ring member 213 is formed by a non-magnetic material having specific gravity larger than that of the rotor core 209.SELECTED DRAWING: Figure 3 【課題】小型化および高効率化を図ることが可能な電動送風機を提供する。【解決手段】回転自在に設けられた回転軸２０７と、回転軸２０７の軸方向Ｇの略中央に設けられた軸受２１２，２１２と、回転軸２０７の一端に設けられた遠心羽根車２０３と、回転軸２０７の軸受２１２を挟んで遠心羽根車２０３とは逆側に設けられるロータコア２１０と、ロータコア２０９の周囲に対向して配置されるステータ２４０と、回転軸２０７の他端に設けられるリング部材２１３と、を備え、リング部材２１３は、ロータコア２０９の比重よりも大きく、かつ、非磁性の材料で構成されている。【選択図】図３
