<p><P>PROBLEM TO BE SOLVED: To provide a water sealing normal temperature shrinkable tube unit which hardly damages a normal temperature shrinkable tube at the opposite end parts of a metal foil forming water sealing layer. <P>SOLUTION: This water sealing normal temperature shrinkable tube unit has a disassemble cylindrical core 1, a water sealing layer 2 obtained by circumferentially winding the metal foil outside the cylindrical core 1 in a cylindrical shape and overlapping its opposite side edge parts, and a normal temperature shrinkable tube 3 for covering the outside of the water sealing layer 2 in a state of elastically expanded, in which the end edges of the end edge parts 2b, 2b in the circumferential direction of the normal temperature shrinkable tube of the metal foil are bent to avoid contact with the normal temperature shrinkable tube. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
