For example, the lower shaft of the main body 200 may have a pivoting structure that is coupled with the upper shaft of the fixed portion 10 in a bearing structure.

The rotation shaft 210 may be vertically coupled to the main body 200 as shown in FIG. 1, or may be parallel and spaced apart from the main body 200 as shown in FIG.

The rotary vane 220 is radially coupled to the rotary shaft 210 and allows the rotary shaft 210 to rotate due to the influence of wind.

It is preferable to select a material having excellent corrosion resistance in consideration of the fact that the rotary vane 220 is made of a material having a light and constant elasticity and is particularly exposed to an outdoor environment.

The wind turbine generator of the present invention includes a plurality of open / close windows 230 in the rotary vane 220, and each of the open / close windows 230 is configured to be opened or closed in one direction, It is possible to improve the rotation efficiency of the rotary part 20 by minimizing the air resistance by allowing the wind force to act only on the windshield 220 and the windshield 230 on the other rotary vane 220. [ Feature.

[

The opening / closing window 230 may be hinged to the through hole 241 to have various embodiments. For example, the opening / closing window 230 may be formed of a short-form or a double-door as shown in FIGS. 4A to 4F, and the hinge 242 may be applied at different positions according to each embodiment.

When the opening / closing window 230 is formed as a side door, each opening / closing window 230 is divided into two unit windows 230-1 and 230-2 so as to be symmetrical, The hinges 242 must be coupled to the through holes 241 of the hinges 241, respectively.

As described above, the wind power generator according to the present invention is configured such that the opening / closing window 230 is opened only in one direction, so that the rotary vane 220, which is symmetrical to the left or right or up and down about the rotation axis 210, all the windows of the rotary vane 220 corresponding to the front surface a are closed and all the windows of the rotary vane 220 corresponding to the rear surface b are opened.
