<P>PROBLEM TO BE SOLVED: To provide a wind power generation device capable of effectively suppressing imbalance vibration or vibration caused by torque fluctuation generated in a drag-type or lift-type vertical shaft wind power generation device equipped with a plurality of windmill blades and comprising a simple vibration control structure manufactured at low cost. <P>SOLUTION: The wind power generation device 1 includes a vertical shaft windmill 2 equipped with a plurality of blades 2a and generating torque by wind acting on the blades 2a, a pole 8 supporting the windmill 2 from a lower end side, and a dynamic vibration absorber 7 mounted to an upper end of the pole 8 or an upper part of the pole 8. The dynamic vibration absorber 7 is composed of a cylindrical weight 7a and a rubber isolator 7b mounted to the weight. <P>COPYRIGHT: (C)2009,JPO&INPIT |
