Abstract
A vertical shaft wind turbine that is superior in a rotational startability, even at a low wind speed, and is suited to a wind power generator that has high rotational torque. Each blade is an upper-and-lower-ends fixed type vertically long blade which is suitable for use as a wind turbine or a water turbine. The string length and thickness of an upper-and-lower-ends fixed type vertically long blade () that is fixed upper and lower ends to a vertical main shaft () gradually decrease from a main part () thereof to tips of the upper and lower inwardly curved inclined parts (B,B), and a cross section of the main part (A) is a lift type. A thickness of the cross-sectional shape is continuously and gradually thins from the main part () to the tips of the inwardly curved inclined parts (B,B).
