Abstract
The present invention relates to a wind direction adjustable blade type vertical axis wind turbine that is configured to allow blades to be automatically swung, thereby making more efficient use of wind power. The wind turbine includes: a rotating shaft adapted to be rotated by means of wind power; an upper plate adapted to be coupled to the upper portion of the rotating shaft; a lower plate adapted to be coupled to the lower portion of the rotating shaft; a plurality of blades disposed between the upper plate and the lower plate; and swing motion units disposed between the top end of each blade and the upper plate and between the underside end of each blade and the lower plate in such a manner as to form the center of rotation of each blade, while allowing each blade to be rotatable in accordance with the wind direction.
