<p>Provided is a fixed-direction rotation windmill that uses a simple mechanism to stably extract wind power as rotary motive force regardless of weather conditions. Wind power vanes (10), wherein the shape of the cross section perpendicular to a shaft (2) is an "open convex polygon" and the convex surface of the convex polygon is configured in a manner so as to be openable/closable, are disposed in multiple levels in a point-symmetrical manner around a rotating axle (1) with the shaft (2) therebetween in a radial shape and equally dividing a circle circumference (n). The outer end of the shaft (2) is affixed to a cylindrical box frame rotating body (20), and the center of the cylindrical box frame rotating body (2) is affixed/supported by the rotating axle (1).</p> |
