PURPOSE:To improve the fixing reliability of a blade by fitting and adhering the blade root section through a resin filler to a fixing metal formed on a hab while penetrating a stopper metal between the fixing metal and the blade root section. CONSTITUTION:A fiber reinforced resin blade 5 has a tubular root section 5a and secured through a fixing metal to a hab 4. The fiber reinforced root section 5a of the blade 5 is adhered through a fiber reinforced resin filler 12 and an adhesive to the fixing metal 7 while plural bolts 13 are penetrated through a collar 14 to the inner diameter side of the blade root section 5a along the circumferential direction of the sleeve section 8 of the fixing metal 7 and tightened by means of a nut 13a. Consequently, the reliability can be improved when fixing a fiber reinforced resin blade to a fixing metal through simple structure. |
