Agitator propeller for producing flow in liquids, which propeller is composed of one or more blades of a hub serving as centre of rotation and a connection rod joining the blades to the hub. To simplify the construction of the agitator and to decrease the danger of blockage, a propeller according to the invention is constructed in such a way that the connection rod, in the direction of rotation of the propeller, is either continuously curved or angularly bent towards the rear and that, at the connection of the connection rod to the blade, the front edge of the connection rod is uniformly connected, reaching to the front edge of the blade.
