PROBLEM TO BE SOLVED: To provide an extrusion-molding machine for the manufacture of a clay molded body which solves rotating inclination of the molded body while suppressing a carrying load. SOLUTION: This extrusion-molding machine is equipped with an extrusion chamber 21 equipped with an extrusion screw conveyor 24 for carrying materials of which the major component is clay, a nozzle 41, a cylindrical rotator 30 which is freely rotatably provided between the extrusion chamber and the nozzle, and a first turning means 110 which is arranged in the rotator, and turns the materials by being integrally rotate-driven with the extrusion screw conveyor. The rotator is equipped with a second turning means 100 which turns the materials when being rotate-driven in the opposite direction from the rotating direction of the extrusion-screw conveyor. A plurality of the first turning means are arranged along an extension axis which extends from the distal end of the extrusion screw conveyor to the nozzle. The second turning means is arranged along the axis of the rotator in spaces between adjacent first turning means. Either one of the first turning means and the second turning means is formed in such a manner that the materials can be pressed to the nozzle by the rotation. COPYRIGHT: (C)2006,JPO&NCIPI
