PIPE BODY CONNECTION STRUCTURE

PROBLEM TO BE SOLVED: To provide a new pipe body connection structure in which one hose is laminated on the other hose.SOLUTION: A hose assembly product 10 is assembled in such a way that a first hose 20 and a second hose 30 are connected under application of a connection pipe 40 having a first engaging convex part 43 and a second engaging convex part 44. The first hose 20 rides over one engaging protrusion 43 of the connection pipe 40 and is engaged with it. The second hose 30 rides over the other engaging protrusion 44 of the connecting pipe 40 and further is installed up to a position where it is laminated at a part of the first hose 20 that has already been installed in advance. The first hose 20 has either one or a plurality of convex parts 21 at a part of its outer circumference that act at position setting members when the second hose 30 is installed at a prescribed position from the installing end 22 of the installed hose end along a pipe passage direction.SELECTED DRAWING: Figure 3 【課題】一方のホースに他方のホースを積層させた新たな管体接続構造を提供する。【解決手段】ホースアッシー品１０は、両端部に第１係合凸部４３と第２係合凸部４４を有する接続管体４０を用いて、第１ホース２０と第２ホース３０とを接続する。第１ホース２０は、接続管体４０の一方の係合突起４３を乗り越えて装着される。第２ホース３０は、接続管体４０の他方の係合突起４４を乗り越え、更に先に装着済みの第１ホース２０の一部に積層する位置まで装着される。第１ホース２０は、装着側ホース端部である装着端２２から管路方向に沿った所定の位置に、第２ホース３０の装着時の位置決め部材として機能する一または複数の凸部２１を、外周の一部に有する。【選択図】図３
