PURPOSE:To simplify installation of the title mechanism by preventing it from being loaded partially, by consisting a driving device of a screwed rotating body, a step for converting the rotary motion into an up-and-down motion, and a motor being connected with them in series. CONSTITUTION:An expansion-contraction driving device of an elastic forming body 11 is composed of a tube 14 which is fit into a cylindrical guiding body 13 in a elevation-free relation, a screwed rotating body which is provided with a screw shaft 32 and a cylindrical screw nut 33 and inserted into the tube, pipes 36 and 37 for converting the rotary motion into a symmetrical vertical linear motion, and a mechanism to prevent the rotating body from being turned from an engaging section 35A. A motor 30 which allows the screw shaft 32 to make positive reverse turn around the shaft is provided in series on the bottom end of the tube 14.
