ABSTRACT:
An agitating vane in which a plate-like vane is disposed at an extreme end of a rotary shaft to agitate liquid has a feature that auxiliary vanes for covering a part of vane with a clearance being left are disposed in front of the surface of the vane in its rotational direction. Accordingly, a phenomenon of peeling-off caused by the eddy flow generated at the rear surface of the vane is eliminated by liquid flowing at a high speed at a clearance between the vane and the auxiliary vanes, a circulation flow of regulated flow state is attained and agitating efficiency is improved.
