PURPOSE: A vane of an aerogenerator is provided to obtain enough torque even in case of gentle wind as a vane plate receives wind force vertically to the direction of wind. CONSTITUTION: A vane of an aerogenerator comprises four vane frame parts(11) and four vane parts(12). The vane frame part comprises vane frames(111a,111b,111c,111d), a second vane plate stopper(112), and a bearing(113). When a vane plate(121) is shut, a second vane plate stopper supports the vane plate. The bearing is formed on one end of the vane frame. The four vane frame parts open and close the vane plate. The vane part comprises the vane plate, an upper and a lower bearing shaft(123), and a first vane plate stopper(122). |
