Abstract
A core tube holding device comprising: a plurality of out-pushing members that are arranged side by side spaced apart in the axial direction, each having a pressing part; a connecting member for connecting the plurality of out-pushing members; a holding member that has at every position in the axial direction a pressed part corresponding to the pressing part, and that is disposed radially outward with respect to the plurality of out-pushing members; and an action unit adapted to exert a force for moving, to one side in the axial direction, a one end out-pushing member which, among the plurality of out-pushing members, is at an end on the one side; wherein: at least one from among the pressing parts and the pressed parts is formed in a tapered shape that spreads radially outward from the one side to the other side in the axial direction, and when the force for moving the one end out-pushing member acts thereon via the action unit, the one end out-pushing member moves to the one side while also pulling the other out-pushing member(s) via the connecting member, and the pressing parts of each of the out-pushing members push the holding member radially outward via the corresponding pres…
