A wind power generating device, wherein a blade (1) having a torsionally flexible structure is installed at a boss part (7) so as to be moved freely only through a flap angle of beta , and a control member utilizing a centrifugal force or an aerodynamic force is installed near the wing end of the blade (1), whereby, since the blade (1) is tilted to a downwind side in a wide flap angle range according to a wind velocity, the rotation of the blade can be controlled. |
