PROBLEM TO BE SOLVED: To reduce the weight of a total wind power generator by making a strut and a stay for fixing the strut out of a flexible material to be used as the functional elements for controlling the revolving speed of the wind power generator, controlling the output and releasing the wind under the strong wind. SOLUTION: In an up-wind type wind power generator, a horizontal support shaft 18 offset by a distance Y is mounted on a lower part of a rotary shaft 2 of a vane comprising an impeller blade 5, a generator 10 and a tail assembly 13, and a yaw device following the wind direction and comprising a yaw tube 22, a bearing and a yaw shaft is mounted. On this occasion, the strut 28 is totally or partially flexible so that its elasticity is utilized, and the elasticity of the stays 33, 33 supporting the strut 28 is also utilized to improve the durability of a generator. The strut 28 is vertically standed by the anchor bolts 34 or the like on the ground 36 by at least three stays 33 with the distribution fitting 31, a lower end of the strut 28 is edged, and fixed to the ground 36 by a supporting plate 35 comprising a recessed void. |
