<p>PROBLEM TO BE SOLVED: To tighten the outer circumference of a pipe with the extreme end of a hose utilizing the inner pressure of the hose so as to prevent leakage by bending the extreme end of an elastic hose inside, and forming the wall thickness of the hose to be thinner following to approaching the extreme end. SOLUTION: The wall thickness of a hose 1 is made taperingly thin toward the extreme end 2 and the extreme end is bent inside, and a pipe A is inserted into the hose 1. When gas or liquid is allowed to flow in the hose 1 and the pipe A connected together in this way and pressure is generated in the hose 1, the elastic hose intends to swell. At this time, the extreme end 2 tightens the outer circumference of the pipe A so as to be sealed up. By such construction, the higher the inner pressure rises, the higher a sealing effect is enhanced and leakage is prevented. By making the wall thickness of a part outside the hose 12 larger than the hose 1 main body, it can sufficiently support the daily use.</p> |
