<p>PURPOSE:To facilitate insertion of an insulated electric wire into the hollow of tube part, which is to accommodate the wire in its hollow, by providing the tube with a cut which reaches inside of the hollow over the whole length of a one-side surface portion and is energized into the blocked state at normal times by the restrative resilience. CONSTITUTION:A composite spiral tube member A is formed out of two tube parts 11, 22 which are laid parallel in a single piece structure. Therein the tube part 11 is provided with a hollow 12 to serve as a fluid passage for a control fluid. The other tube part 21 is provided with a cut 23 over the whole length of the outside surface to accommodate an insulated electric wire in continuity having an excellent anti-bending property in order to respond to the expansion/contraction effect of the member itself, and a hollow 22 is provided. Thereby the hollow 22 is exposed by pushing open the cut 23 appropriately, and electric wire is easily inserted into the exposed hollow 22.</p> |
