<P>PROBLEM TO BE SOLVED: To provide a wind power generator which can prevent quick turning of a wind mill unit even with a simple structure. <P>SOLUTION: In the wind power generator having a horizontal shaft wind mill, a wind mill unit comprising a blade, a shaft, a box and the like is attached to a tower. The tower is rotatably provided on a base supporting the tower. A sub-blade is provided in the direction perpendicular to a main-blade for rotation-driving the generator at the rear of the main blade. Thus, the tower is rotated by the rotation-driving force of the sub-blade. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
