ABSTRACT:
In an integrated vane1for use in wind or water, main blades3arranged around an axial shaft2of the vane and support blades4for joining the main blades to the axial shaft are integrally formed with light and high strength fiber material such as glass fibers and carbon fibers. The main blade is symmetrical or asymmetrical in its cross sectional view and the support blade is symmetrical in its cross sectional view. The upper support blade may be asymmetrical in its cross sectional view and the lower support blade may have an up-and-down reversed shape of that of the upper support blade. A mountain-shaped portion may be formed at the ends of the main blade for reducing noise. The strength of crossing portions between the main and support blade of the vertical axis vane for use in wind or water is thus improved.
