To solve the problem, wherein a blade material deteriorates and cracks by the high-speed repetition of mechanical vibration and pulsation in the blade of a windmill since the windmill is rotated speedily by strong wind in a storm, such as a typhoon, and finally the internal stress of the material exceeds a breaking point, leading to damages of the blade.
In the wind power generator comprising the windmill that is rotated by capturing natural wind, and a storage battery for converting the rotational energy to an electric energy for storage, a centrifugal impeller provided side by side with the rotary shaft of the windmill coaxially, and a fan having a casing in which the centrifugal impeller does not capture natural wind are formed, thus preventing the overspeed of the windmill accompanying an increase in the natural wind by the load generated by the fan, based on the rotational force of the windmill.
