<P>PROBLEM TO BE SOLVED: To provide a wind turbine for wind power generation reducing the number of component members, facilitating positioning and assembling, and rotating with efficient electric power generation efficiency. <P>SOLUTION: The wind turbine for wind power generation is equipped with a plurality of blades 20 provided around a support pipe 10 connected with a power generator 1 at specified angle intervals, and a plurality of struts 40 connecting each of the blades 20 with the support pipe 10. The blades 20 are formed to have streamline shaped blade profiles. Blade base parts 21 in which trailing edge sides are notched while the leading edge sides of chord length are left in support pipe sides with respect to wing chords, ribs 23 connecting inner sides of notch parts 22 in the blade base parts 21, and recessed parts 24 formed by the blade base parts 21 and the ribs 23 are integrally formed. One ends of the struts 40 abut on the blades 20 and are fixed by first fixation screws 61 penetrating through holders 50 fitted and inserted into inside of the blades 20 and recessed parts 24, and the other ends of the struts 40 are fixed into hubs 30 fitted into the support pipe 10 by second fixation screws 62. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
