The rotating shutter for window or door openings comprises at least one rotationally lodged wing (12) which can be swung between an opened and a closed position by means of an electrical motor. In order to provide a rotating shutter which can be simply mounted and easily retrofitted, the invention foresees that the electrical motor be fixed on the wing (12). Said motor is engaged by at least one movable gearing element (44) on a reaction member (32) lodged on a side of the window or door opening in such a way that a torque is applied on the wing (12) in the direction of closing or opening. |
