<p><P>PROBLEM TO BE SOLVED: To provide a metal touch flexible tube appropriate for a place where vibration displacement is large, having flexibility as effective as using a metal packing, structured by an end part overlapping piece which is made by bending an end part of extension part which is continuously formed and to provide a packing effect having longer life without intervening a packing and to provide a mushroom-like single thread which is not annealed so that the tube becomes appropriate for use in the place where vibration displacement is large and thus provide the tube applicable for the place where vibration displacement is large. <P>SOLUTION: The metal touch flexible tube consists of a flex tube and an angle-expanding end part overlapping piece which is a double-folded angle-expanding part formed at a predetermined angle with an end part of an extending part formed continuously with the tube. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
