PROBLEM TO BE SOLVED: To provide a stay ring of a hydraulic machine that can reduce a loss of an inlet flow of guide vanes.SOLUTION: A stay ring 10 of a hydraulic machine according to an embodiment comprises an annular upper wall 11, an annular lower wall 12 opposed to the upper wall 11, and stay vanes 3 provided between the upper wall 11 and the lower wall 12. Each of the stay vanes 3 comprises a vane body part 13, and wall side parts 14 and 15 provided on the side of the upper wall 11 and on the side of the lower wall 12 with respect to the vane body part 13 respectively. An outlet vane angle θ3 of the wall side parts 14 and 15 is smaller than an outlet vane angle θ4 of the vane body part 13.SELECTED DRAWING: Figure 3 |
