Abstract: PURPOSE: To enhance the reliability to the strength of runner by restricting the hight of flow passage at the edge of a runner blade within a specified range with the outside diameter of the runner blade and by inhibiting stress level.  
     CONSTITUTION: The axis of ordinate represents the ratio σ/σ 0  between runner stress σ and the conventional runner stress σ 0 . The axis of abscissas represents the relative ratio B/D between the height of flow passage B at the periphery of a runner blade 12 and blade periphery diameter D. σ/σ 0  has a tendency to be identical to 1.0 in the region of B/D≤0.085 and σ/σ 0  tends to exceed 1.0 in the region of B/D> 0.085. A runner having no runner band is made by establishing related dimensions within the range of B/D≤0.085, thereby inhibiting stress level and enhancing the reliability of runner strength.
