<P>PROBLEM TO BE SOLVED: To largely reduce time and labor required for manufacture, assembling, inspection and maintenance, while largely improving transport performance, in a blade of a horizontal shaft windmill. <P>SOLUTION: This blade of the horizontal shaft windmill is divided into an inner blade part 11 on the blade root side and an outer blade part 12 on the blade end side in a central part in the longitudinal direction. A metallic plate 13 is arranged between the inner blade part 11 and the outer blade part 12, and the inner blade part 12 and the outer blade part 13 are connected by a turnbuckle 20 composed of a nut 21 and two bolts 22. That is, a through-hole 13a and a cutout part 13b are arranged in the metallic plate 13, and the bolts 22 are locked on the inner blade part 11 and the outer blade part 12, and the inner blade part 11 and the outer blade part 12 are connected by being fastened by rotating the nut 21 inserted into the through-hole 13a of the metallic plate 13 in the predetermined direction by a tool inserted from the cutout part 13b. <P>COPYRIGHT: (C)2007,JPO&INPIT |
