In addition to this, the upper rotary generator 103 and the second lower rotary generator 105 also continue to generate power according to the flapping of the flexible planar body 101. As a result, even if the wind speed changes every time when the wind is blowing, the respective rotary generators 103, 104, 105 are constantly operated and the power generation is not interrupted. When the wind blows, vibration is excited in the flexible planar body 101. The vibration generated in the leeward reinforcing upper corner portion 1012 is transmitted to the rotating shaft 1031 of the upper rotary generator 103 by the arm member 107 to drive the upper rotary generator 103. As a result, vibration energy generated in the reinforcing upper corner portion 1012 on the leeward side is converted into electric energy. First, the energy converter A is arranged so that the surface portion 1a of the flexible flat body 1 is substantially parallel to the wind direction, in other words, the horizontal rail 6 is substantially parallel to the wind direction.
