2. Description of the Related Art In recent years, a wind power generation device has been attracting attention as a renewable energy power generation device due to an increase in environmental awareness. The one described in Patent Document 1 is known as an example of a wind turbine generator.
This wind turbine generator has a rotor having a plurality of blades attached to a hub. The rotor is mounted on a nacelle located on a tower standing on land or offshore. In this type of wind power generation device, the blades receive wind and the rotor rotates, and this rotation is transmitted to the generator housed in the nacelle so that electric power is generated in the generator.

However, in the conventional wind turbine generator described above, a large blade is attached to the rotor and the blade is mounted on the nacelle located on the tower. Is also easy to receive. In particular, when a strong wind blows, it receives a large wind load and vibrates, which may cause noise and damage to the structure. In addition, it cannot be said that the wind hitting the blades can be used efficiently, and the power generation efficiency is not sufficient. Furthermore, in order to obtain a desired amount of power generation, a tower must be newly installed, which requires a large installation space and a great installation cost.

The present invention has been made in view of the above circumstances, and it is possible to effectively use a space to install in a compact manner, achieve a desired amount of power generation in a small installation space, and efficiently use wind to improve power generation efficiency.
