Claim:
1. A vertical-axis wind power generator having adjustable-angle rotating blades comprising: a main shaft vertically extending; a support arm box having upper and lower support arms that are coupled to the main shaft to be spaced apart from each other; a rotating blade having a center shaft that is rotatably coupled to the upper and lower support arms of the support arm box; upper and lower support arms for a wind direction key respectively coupled to upper and lower positions of the support arm box of the main shaft; a wind direction key coupled through the upper and lower support arms for the wind direction key; first angle adjustment means installed between the lower support arm of the support arm box and the lower support arm for the wind direction key to make the rotating blade coincide with a wind direction by rotating the rotating blade against the upper and lower support arms at the same angle in a clockwise direction when the support arm box is rotated in an angle range of 45° to 135° in a counterclockwise direction and to make the rotating blade vertical to the wind direction by rotating the rotating blade against the upper and lower support arms at the same angle in the clockwise direction when the support arm box is rotated in an angle range of 225° to 315° in the counterclockwise direction; a second angle adjustment means installed between the lower support arm of the support arm box and the lower support arm for the wind direction key to maintain the angle of the rotating blade against the upper and lower support arms in an angle state of 135° when the support arm box is rotated in an angle range of 135° to 225° in the counterclockwise direction; and a third angle adjustment means installed between the lower support arm of the support arm box and the lower support arm for the wind direction key to maintain the angle of the rotating blade against the upper and lower support arms in an angle state of 315° when the support arm box is rotated in an angle range of 315° to 45° in the counterclockwise direction.
