で好ましくない。(Section B to be solved by the invention) However, in this conventional heat-shrinkable tube diameter expansion device, the heat-shrinkable tube is simply fed within the heating tank while being supported by support rollers. The heat causes the heat shrink tube to expand axially between the support rollers. If a product is made of a heat-shrinkable tube that remains extended in the axial direction during diameter expansion, the heat-shrinkable tube will also shrink in the axial direction when it is heated and shrunk during use, which is undesirable.
