PURPOSE:To improve disadvantages such as the strict accuracy control of weight and a center of gravity position and poor efficiency in the manufacturing viewpoint of a windmill blade. CONSTITUTION:A method for adjusting the center of gravity moment of a windmill blade comprises a process of inserting a hollow insertion rod whose feed groove is formed on its outer peripheral surface at an end part 7 into a hollow part 4 formed in the blade width direction in a main beam 3, processes of moving a weight 5 threadedly fitted to the end of the insertion rod, and setting the centers of gravity moment of respective windmill blades which form a pair of windmills to a prescribed position where the centers of gravity moment are substantially equal, a process of filling the hollow parts 4 on the blade end side and blade root part of the weight 5 provided in the prescribed position with a foaming resin 9, solidifying the resin and fixing the weight 5 at the prescribed position. |
