PROBLEM TO BE SOLVED: To facilitate carriage to a mountaintop or the like by making a torque blade short by making area receiving wind pressure larger than that of a former wind turbine. SOLUTION: In a horizontal shaft type and drag type wind power generator, assemblies in which a plurality of hinge type blades are arranged in a grid shape are gathered and attached on an leading end part of a large blade frame, and six large blades are attached on a horizontal main shaft. In an open close structure of the hinge type blade, concentric gears attached to chains rotate in mutually opposite direction to open and close the blades attached to ends of shafts thereof by moving two straight rod shape chains 6 in mutually opposite direction by an electric actuator 8. Power factor of power generation can be rapidly increased by receiving strong wind pressure by making the blade in a plate shape at an upper part of a main body and minimizing rotation wind pressure by making the blade in the grid shape in other angles by using the structure.
