PROBLEM TO BE SOLVED: To restrain divided stator blade parts from deforming at the time of installation because of the occurrence of overlapping and warping at butting parts of the stator blade parts.SOLUTION: A stator blade part 70 is formed as one ring by making divided stator blade parts 70A and 70B butt against each other at two butting end parts in a radial direction. An outer peripheral rim 73a of the divided stator blade part 70A is provided with a cutout K cut out in a circumferential direction from a butting face, and a clearance S is formed between the outer peripheral rim 73a and an end part 73b2 of an outer peripheral rim 73b of the divided stator blade part 70B at the time of installation. |
