Eccentricity is not allowed to occur in a blade section, and a blade section is maintained in a stable installation state. A hook section124, which is composed of a shaft section125and an end section126provided with a corner section132that protrudes as a ledge farther to the outside in the radial direction than this shaft section125, is formed in a blade section120. A hook hole144, which allows the passage of end section126of hook section124, is formed in a bolt section140. Engaging sections150are formed around hook hole144. Corner sections132of end section126of hook section124are engaged with engaging sections150when blade section120and bolt section140are 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 section120is rotated by about 60° towards the front in a direction of screwing rotation S with respect to bolt section140after inserting and passing end section126of hook section124through hook hole144.
