<p>PURPOSE:To decrease the rotational speed of a wind mill and a falling-down moment acting on a wind mill tower by providing a mechanism for moving the mill to the rear side of a guide way as well as the guide way for directing wind introduced thereinto to the mill. CONSTITUTION:Wind introduced with an introducing way 1 increase its speed when it is narrowed through buffles 3 to strike at a wind mill 4, and to rotate the same. An arm 5 is pushed the central side according to the magnitude of wind force and then moved from the main way of wind. The arm 5 moves to the inside of the buffle 3 at the time of strong wind to reduce load to the mill 4. Further, the wind force to a body case is escaped and reduced by means of a link 6. It is, thus possible to reduce following-down moment acting on the tower of the mill as well as to the rotational speed thereof.</p> |
