A vane attack angle regulator of a vertical shaft wind-driven generator includes a vertical rotation shaft (1), a rotating cantilever support wing fixed on the rotation shaft and vanes (13) attached to the support wing; one wind wheel is comprised of the vanes. At least one cam (6) is set in the rotation shaft direction, and the axis of the cam is parallel to the axis of the rotation shaft. Attack angles along the contour line of the cam are equal to the difference between the azimuth and the rotating angle in all points. Each vane (13) can rotate relative to the support wing, and a driving unit connects the cam with the vanes.
