PROBLEM TO BE SOLVED: To provide a windmill blade which has desired rigidity as a divided-structure windmill blade, and can be assembled by simple work.SOLUTION: A reinforcing ring 8 connected to a halved windmill blade 5 while possessing rigidity has a plane shape, as an inside face shape, which follows external surface shapes at a skin portion of a root-side blade 6a at the surroundings of a divided part 10 and a skin portion of a tip-side blade 6b. By this constitution, the reinforcing ring 8 can be fixed to a blade outer skin 6 of the windmill blade 5 in a state of being tightly adhered to the blade outer skin 6, and the divided-structure windmill blade 5 can possess rigidity. |
