PROBLEM TO BE SOLVED: To provide a vertical shaft type wind power generator in which power generating efficiency and on-wind availability are increased by restricting also an attenuation amount of wind speed flowing into the leeward side vertical blade low while kinetic energy of components of wind speed of a blow-up wind or blow-down wind in parallel with a wind turbine rotary shaft is being efficiently converted to rotation energy of the vertical shaft wind turbine by using the parallel blade.SOLUTION: This invention relates to a vertical shaft type wind power generator 10 in which a lift force type vertical shaft wind turbine 20 for rotating a rotary shaft by torque mainly caused by lift force generated at a plurality of vertical blades 22 fixed to a rotary shaft 21 through supporting arms and a power generator 30 for converting rotation energy of the rotary shaft into electrical energy are installed. A plurality of parallel blades 23 for assisting a rotation of the rotary shaft while being fixed to the vertical blades correspond to at least one of the following items (1) and (2). (1) the parallel blade fixed to the upper part of the vertical blade for blow-up wind, and (2) the parallel blade fixed to the lower part of the vertical blade for blow-down wind. |
