<p><P>PROBLEM TO BE SOLVED: To provide a joint mountable/demountable on/from a pipe body such as a hose with easy operation. <P>SOLUTION: A joint body 12 has supporting portions 12A, 12B into which inner pipes 44A, 44B of the hose 40 are inserted. On one side of a protruded portion 14 of the peripheral face of the joint body 12, two first bagged portions 18 each formed of a rubber are arranged which are filled with fluid 24. On the other side of the protruded portion 14, two second bagged portions 20 each formed of an annular rubber are arranged between the supporting portion 12A and the inner pipe 44A and between the supporting portion 12B and the inner pipe 44B, which are filled with fluid 24. Each second bagged portion 20 and each bagged portion 18 are communicated with each other via a connection pipe 22. A nut 16 is provided on the joint body 12, and the nut 16 is fastened to the side of the protruded portion 14 to crush the first bagged portions 18. Thus, the fluid 24 moves through the connection pipes 22 to the second bagged portions 20, and the second bagged portions 20 are expanded to thrust wall portions of the inner pipes 44A, 44B. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
