PROBLEM TO BE SOLVED: To provide a flexible pipe joint easily determining completion of insertion connection of a flexible pipe in a directly intuitive manner.SOLUTION: A flexible pipe joint is a joint for connecting a flexible pipe F, the outer periphery of which irregularities are continuously formed, to a gas conduit in an inserted manner. The flexible pipe joint includes: an airtight packing 4 arranged in an inner hole 1f of a joint body 1, formed into a cylindrical shape, and sealed by closely adhering to the outer peripheral surface of the flexible pipe F; and a spring 5 pushing the airtight packing 4 in an axial direction. The air packing 4 has a front layer part 4k comprising an elastic material pushed against a flexible pipe annular projection part FP and having durability, and an inner layer part 4b arranged inside the front layer part and having easily deformable property.SELECTED DRAWING: Figure 2B |
