長する複数の支柱に固定された板状の羽根にその
前縁から後縁に沿う反りを持たせるとともにその
前縁と外周縁との角隅部を切り欠いた残りの前縁
をシユラウドケーシングに穿設された円形の開口
を貫通して前方に突出させ、かつ、後縁の背後に
微少間隙を隔てて後縁の外径とほぼ同じ外径を有

ン。 The plate-shaped blades fixed to a plurality of supports extending in the radial direction of the spider fixed to the rotating shaft are curved from the leading edge to the trailing edge, and the corners between the leading edge and the outer peripheral edge are curved. The remaining leading edge that has been cut out passes through a circular opening drilled in the shroud casing and projects forward, and is spaced behind the trailing edge with a small gap so that the outside diameter is approximately the same as the outside diameter of the trailing edge. A fan characterized by having a circular back plate.
