Kagoshima (JP) (57) ABSTRACT A wind power generator comprises a ?rst power generator

(21) Appl. No.: 13/379,224 including a rotor arranged so as to be coaxial with a rotation shaft and generates electric power by the rotation of the rotor,

(22) PCT Filed: Dec_ 27, 2010 a ?ywheel which is coaxial with the rotation shaft and arranged through a one-way clutch so that when the rotation

(86) PCT NO _ PCT / JP10 I73 577 shaft increases its speed, the ?ywheel is in an integrally rotat " ing state with the rotation shaft, and when the rotation shaft

§ 371 (c)(1), reduces its speed, the ?ywheel is separated from the rotation (2), (4) Date: Dec. 19, 2011 shaft to rotate inertially, a second power generator including

a rotor arranged so as to be coaxial with the ?ywheel and (30) Foreign Application Priority Data rotate integrally with the ?ywheel generates the electric

power by the rotation of the rotor with the rotation of the May 31, 2010 (JP) ............................... .. 2010-125350 ?ywheel, and an output portion which externally outputs any Jun. 7, 2010 (JP) 2010-130372 one of the electric powers generated by the ?rst and second

Jun. 14, 2010 (JP) ............................... .. 2010-135106 power generators.
