PURPOSE: A vertical-axis wind power generator is provided to minimize a flow resistance of a blade plate, retain the smooth torque by preventing the generation of a gap caused by a change of curvature or a size of the blade plate. CONSTITUTION: A vertical-axis wind power generator comprises a rotary shaft(20), a plurality of supporters(30) and a blade plate(40). A plurality of the supporters is arranged on a circumference of the rotary shaft radially. The blade plate is installed on each end of the supporters at a level with the rotary shaft. The blade plate comprises a support blade and singular or plural variable blades(43,45) The support blade is connected to the supporters. The variable blade is separated from the support blade A connection member connects the support blade and the variable blade. The variable blade is rotated around the support blade about the inside or outside of rotational direction of the blade plate by a driving device for a variable rotation. |
