PROBLEM TO BE SOLVED: To reduce a mechanical load on a component caused by the fluctuation of torque generated by receiving wind by a windmill blade.SOLUTION: A window power generator converts torque generated by receiving wind by windmill blades 5 into electric power by a generator 20. The wind power generator includes a speed-increasing machine 10 provided on a torque transmission path from the windmill blades 5 to the generator 20, and a first bush 102 and a second bush 106 for supporting the speed-increasing machine 10. The rigidity of the first bush 102 and the second bush 106 is set so that the natural frequency of a power transmission system from the windmill blades 5 to the generator 20 may be deviated from a natural number multiple of a product of the number of revolutions of the windmill blades 5 and the blade number of the windmill blades 5, and the number of revolutions of the windmill blade 5. |
