Since the second connecting rod 8, which is pivoted on the other side of the first connecting rod 7, is in an upper bound, the upper flat plate 1a on the other side is pushed by the horizontal rod 5, and the upper flat plate 1a on the other side (on the right side in the drawing) The damper blade C is always in the closed state. Conversely, if the damper blade C on the other side is in the open state, the damper blade M1c on the - side is in the closed state.

パ羽根Cは、前記した作用により閉状態になる。Therefore, as shown in FIG. 1, when the wind W is blowing in the direction of the arrow, the damper blade C on one side, which is in the open state, receives the wind pressure of the wind W and generates a rotational force. On the other hand, since the damper blade C on the other side is in the closed state, the rotation blocking force due to the wind pressure of the wind W is reduced, and the damper blade C as a whole rotates vigorously in the opposite direction due to the slight wind pressure. Then, when the damper blade C on the other side rotates to around the example, the wind W
In response to the wind pressure, the upper flat plate 1a rotates upward and the upper flat plate 1b rotates downward, resulting in an open state. At this time, the damper blade C rotated to the other side becomes closed due to the above-described action.

風圧による回転阻止力を完全に低減することができる。Further, an opening/closing plate 6 is attached to the inner base end of the upper and lower flat plates l so that it can be opened and closed, so that when the damper blade C is in the open state, it can be opened and closed as shown in FIG. 4(a). Board 6
will be in a closed state and will be completely exposed to the wind from between the upper and lower plates l. Therefore, the rotational force due to wind pressure can be further increased. Further, as shown in FIG. 4(b), when the damper blade C is in the closed state, the opening/closing plate 6 opens due to the wind pressure of the wind W, and the wind passes between the upper and lower flat plates 1. Therefore, the rotation blocking force due to wind pressure can be completely reduced.
又、この発明を発電用の風車として使用するとき等は、
安定した電力を得るために、風力に応じて風車の回転速

In order to obtain stable power, a device is required to control the rotation speed of the wind turbine according to the wind force.
そのため、例えば、第1連結杆7、軸7a、当接部10
