<P>PROBLEM TO BE SOLVED: To improve a variable pitch blade, more specifically to provide the blade for a wind power generator capable of increasing rotation torque and enabling power generation even at low wind speeds while controlling rotation in strong winds by using an auxiliary blade. <P>SOLUTION: To solve the above problem, the blade for the wind power generator is constructed so that the main blade and the sub blade overlap with each other in high speed rotation of a rotor and a clearance is formed between the main blade and the sub blade in low speed rotation of the rotor. <P>COPYRIGHT: (C)2008,JPO&INPIT |
