摘要： The invention disclosed a vertical axis wind turbine with automatic blade adjustment of blade angle, comprising a pillar, a rotational axis disposed at the pillar, and a plurality of wind turbine assemblies rotating around the pillar. Each wind turbine assembly comprises a blade, a support, and a swing axis. The swing axis comprises an axial core element and an axis element, fixed to the blade and uses the axial core element to engage the support to make the blade to swing on the axial core element with an angle within ±90°. The blade comprises first and second blade areas, with an imaginary line of center of gravity dividing first and second blade areas. When the blade is at 0°, the imaginary line overlaps the projection of centrifugal force direction of an extension line of axis of the swing axis, but the line shall not actually overlap the extension line.
