Eccentricity is not allowed to occur in a blade section, and a blade section is maintained in a stable installation state. A hook section, which is composed of a shaft sectionand an end sectionprovided with a corner sectionthat protrudes as a ledge farther to the outside in the radial direction than this shaft section, is formed in a blade section. A hook hole, which allows the passage of end sectionof hook section, is formed in a bolt section. Engaging sectionsare formed around hook hole. Corner sectionsof end sectionof hook sectionare engaged with engaging sectionswhen blade sectionand bolt sectionare relatively moved in the direction in which they move away from each other in the direction of an axis O in the state in which blade sectionis rotated by about 60° towards the front in a direction of screwing rotation S with respect to bolt sectionafter inserting and passing end sectionof hook sectionthrough hook hole
