<p>A rolled body holder comprising a center shaft member in the form of a lead screw connected to a handle, a cam member threaded with the center shaft member, and a plurality of segments forming a cylindrical body covering the center shaft member and the cam member. The cam member comprises a plurality of rails, and each of the rails comprises a cam face with a radially varying height. Each of the segments comprises a follower part fitted to the rail and relatively slidable along the cam face and an outer surface part on which a large number of projected parts are formed. When the cylindrical body is inserted into the paper tube of a rolled body and the handle is rotated, the center shaft member is rotated to move the cam member in the longitudinal direction. Then, the portion of the cam face higher in the radial direction is brought into contact with the follower part, and each of the segments is expanded in the radial direction so that the projected parts bite into the inner surface of the paper tube. As a result, the rolled body can be easily and securely held by a simple structure.</p> |
