<p>PURPOSE:To expand/contract a fitting following expansion/contraction sliding of a pipe for preventing removal of the pipe from the fitting even when the pipe moves largely so as to prevent water leak by fixing circular end parts of a pair of outer pipe members on each pipe by a fixing means, and providing a flexible member between circular diameter-enlarged end parts of the outer pipe members to be freely expanded/contracted. CONSTITUTION:A joint 3 for connecting end parts of adjacent pipes 2, 2' to each other is provided with circular end parts 4', 4' to be engaged with parts of the pipes 2, 2'. A pair of outer pipe members 6, 6' provided with circular diameter-enlarged parts 5, 5' extended from the circular end parts 4, 4' over the joint 3 are provided. A flexible member 7 is provided between the circular diameter-enlarged parts 5, 5' of the outer pipe members 6, 6' to be freely expanded/contracted. The circular end parts 4, 4' of the outer pipe members 6, 6' are fixed to the respective pipes 2, 2' by a fixing means. Seal members 17, 18 are disposed between the circular end parts 4, 4' of the outer pipe members 6, 6' and the surfaces of the pipes 2, 2' respectively.</p> |
