<P>PROBLEM TO BE SOLVED: To provide a technique capable of preventing blade breakage accident by a blast and simplifying the operation for restarting operation. <P>SOLUTION: The wind power generator includes a tower formed upright on the ground, a nacelle fixed on the tower, and a plurality of blades fixed rotatably on the nacelle via a hub. At least one of the blades includes a top end separating structure to be separated from the other portions in the case wind pressure of a predetermined level or higher is applied. The blade comprising the top end separating structure is stopped at a position higher than the horizontal position at the stoppage of the rotation. <P>COPYRIGHT: (C)2011,JPO&INPIT |
