2. Description of the Related Art In recent years, the continuous consumption of fossil fuels has increased the concentration of carbon dioxide in the earth's atmosphere, leading to a global warming phenomenon. This global warming phenomenon causes abnormal weather such as a drought and a typhoon in various parts of the earth, and as a result, many lives have been lost.

[0004] Under such circumstances, there is a movement to commercialize wind power generation. Wind power generation is expected as clean energy that is non-polluting and does not generate dangerous substances such as radioactivity. In addition, since the wind that exists naturally is used as the energy source, once the equipment is provided, there is an advantage that power generation can be performed semipermanently at almost no cost.

[0005] By the way, conventional wind turbines that have been used for wind power generation are arranged with the direction fixed to the direction of the wind that blows best on the land. Therefore, when wind is blowing from the direction in which the windmill is facing, power can be efficiently generated, but when the wind direction changes, the windmill cannot be turned. This makes it difficult to fully utilize the precious wind energy, and power generation efficiency is poor. Therefore, it has been desired to develop a structure that can effectively take in the wind and turn the windmill even when the wind direction changes.

Then, as shown in FIG.
While being rectified, it is taken into the casing 13 and hits the blade 7 to be discharged from the discharge port 17.
The impeller 5 rotates by the wind force at this time, and a rotational force is generated. This torque is transmitted to the pulley of the generator via the pulley 9 and the belt 11, and drives the generator to generate power. In the casing 13, the side receiving the wind pressure of the blade 7 has a greater wind pressure than the outside, and conversely, has a negative pressure on the rotation direction side of the blade 7. Therefore, the impeller 5 is easily rotated, and the wind can be used more efficiently.
