<p>PURPOSE:To accurately adjust pitch angle with respect to wind pressure by interposing a link-like pitch angle adjustor having a resilient member between a spoke and a wind mill blade. CONSTITUTION:A plurality of upright rods 38 project at intervals at the lee side of a spoke 34, a horizontal rod 39 is laid at the middle height of the upright rods 38, and springs 40 and a shock absorber 41 are coaxially mounted in the middle point between the horizontal rod 39 and wind mill blades 35, and a link-like pitch angle adjustor 42 consists of both the horizontal rod 38 and the springs 40. The freedom of the mounting of the springs 40 may then be increased so that the pitch angle can be adjusted accurately according to wind pressure.</p> |
