PROBLEM TO BE SOLVED: To provide a multistage wind power generator at a low cost by using a plate-like wing body for obtaining the sufficient torque in stead of a conventional S-shaped wing body around a vertical rotary shaft. SOLUTION: Multiple stages of structures K respectively formed of a pillar 1, a beam member 2 and a floor member 2a are provided by using the pillars 1 thereof in common, and a bearing 5 at a vertex part and a bearing 6 at a bottom part of each structure K are supported by a rotary shaft 7, and plural wing bodies 8 are radially projected from each rotary shaft 7 so as to form a vane F. Since doors 10 respectively provided with a hinge to be opened in the only constant circumferential direction are installed in the wing body 8, in the case where the wind blows in any direction, the doors 10 are opened and closed so as to rotated the vane F, and the power is generated by a generator 3 using the torque. Since the vanes F are provided in multiple stages, the power is appropriately generated in response to the wing speed different at each height. |
