In other words, the wind passing through the hollow portion is accelerated by the venturi portion, the rotation speed of the rotor portion is increased, and the main body portion can take out large generated power for a small size. In a configuration in which a plurality of rotating blades are arranged in series, the reduced diameter venturi section is secured for a certain length in the flow path from the air inlet side to the air outlet side of the hollow part. In other words, it may be formed in a reduced diameter cylindrical shape. The formation position of the venturi portion in the hollow portion may be set arbitrarily. A flow path (wind gap) communicating the air inlet and the air outlet is provided at a position near the air inlet or a position near the air discharge port. A wind power generation unit may be placed on the side. By this venturi, the wind passing through the hollow is accelerated, the rotation speed of the rotor is increased, and the main body can take out large generated power for a small size.

By controlling the wind with the horizontal wings and vertical tails, the wind can be taken into the main body with the main body always facing upwind. Further, a V-shaped or star-shaped wing may be provided to the main body in end view.
