Abstract

A mandrel has an outer peripheral member that shapes an outer peripheral surface of a mandrel, and a regulation member that regulates movement of the outer peripheral surface toward the radially inner side. A manufacturing device for a tubular member includes a radial movement mechanism that deforms the outer peripheral surface by actuating the regulation member into the outer peripheral surface in a winding shape and the outer peripheral surface in a separable shape, the separable shape being obtained by moving the outer peripheral surface in the winding shape toward the radially inner side and allowing the mandrel and the tubular member to be separated in the axial direction of the mandrel.
