Propeller device for whirligigs, of the type composed of a hollow handle, the end of which protrudes an axis that includes a coupling and acting head on the whirligig, essentially characterized in that the shaft is constituted by a rod provided with a coating that inside the handle forms a helical passage through an expansion spring supported by one end on a stop of the rod, while the other end of said spring rests on a guide throttle, internal handle itself traversed by the helical so that when pressing vertically the tubular body on the perinolas the spring is compressed, rotating the helical axis, through the guide hole, so that said rotation of the shaft is transmitted to the whirligig making it rotate.
