A wind power generator comprises a first power generator including a rotor arranged so as to be coaxial with a rotation shaft and generates electric power by the rotation of the rotor, a flywheel which is coaxial with the rotation shaft and arranged through a one-way clutch so that when the rotation shaft increases its speed, the flywheel is in an integrally rotating state with the rotation shaft, and when the rotation shaft reduces its speed, the flywheel is separated from the rotation shaft to rotate inertially, a second power generator including a rotor arranged so as to be coaxial with the flywheel and rotate integrally with the flywheel generates the electric power by the rotation of the rotor with the rotation of the flywheel, and an output portion which externally outputs any one of the electric powers generated by the first and second power generators. |

1. A wind power generator comprising:
a windmill which receives wind power to be rotated in a constant rotational direction around a predetermined rotation shaft line; first power generation unit that has a rotor, which is arranged so as to be coaxial with a rotation shaft of the windmill and rotate integrally with the rotation shaft, and generates first electric power by the rotation of the rotor with the rotation of the rotation shaft; a flywheel which is coaxial with the rotation shaft and arranged through a one-way clutch so that when the rotation shaft increases its speed in the constant rotational direction, the flywheel is in an integrally rotating state with the rotation shaft and rotates with increased speed, and when the rotation shaft reduces its speed in the constant rotational direction, the flywheel is separated from the rotation shaft to rotate inertially; second power generation unit that has a rotor, which is arranged so as to be coaxial with the flywheel and rotate integrally with the flywheel, generates second electric power by the rotation of the rotor with the rotation of the flywheel, and is different from the first power generation unit; electric drive unit that rotates and drives the flywheel in the constant rotational direction; drive electric power supply unit that supplies drive electric power to the electric drive unit; rotational speed level detection unit that detects a rotational speed level of the flywheel; drive electric power control unit that when the detected rotational speed level is less than a previously determined threshold rotational speed level, makes the drive electric power supply unit supply the drive electric power to the electric drive unit; and output unit that receives either of (a) the second electric power generated by the second power generation unit, in which the second electric power is generated by the integral rotation of the rotation shaft when the shaft increases its speed and by the integral rotation of the flywheel that is rotating at a higher speed than the rotation shaft when the rotation shaft reduces its speed, the flywheel being separated from the rotation shaft to rotate inertially, or (b) both of the first electric power generated by the first power generation unit, in which the first electric power is generated by the integral rotation of the rotation shaft, and the second electric power generated by the second power generation unit, and externally outputs the electric power inputted.
