<p>PURPOSE: To improve a device for hinge-joining a pipe in a prescribed form so as to be formed into an extremely simple and light structure, and reduced in manufacturing cost for ensuring absorption of all resulting behaviors and stresses, in spite of its simple and light structure. CONSTITUTION: A spring element encircling a bellows conduit portion 3 has two casing portions 6, 7 joined to pipe sections 1, 2 and engaged with each other at their projections 8, 9 in the axial direction and at least one ring member 10 coaxial with the bellows conduit portion 3 for joining both casing portions 6, 7 in the areas of their projections 8, 9 throughout their peripheries.</p> |
