ABSTRACT:
A rolled body holder includes a center shaft member serving as a lead screw connected to a handle, a cam member screwed to the center shaft member, and a plurality of segments which form a cylindrical body covering the center shaft member and the cam member. The cam member includes a plurality of rails, and each of the rails includes a cam surface with a radially varying height. Each of the segments includes a follower part fitted to the rail and relatively slidable along the cam surface and an outer surface part on which multiple projections are formed. When the cylindrical body is inserted into a 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, a portion of the cam surface, which is higher in the radial direction, is brought into contact with the follower part, and each of the segments extends in the radial direction so that the projections bite into an inner surface of the paper tube. As a result, the rolled body can be easily and securely held with a simple structure.
