が形成されている。 The insertion hole 6 has the largest diameter flange joint part 8 on its open end side, and this diameter and width are the same as those of the pipe 1.
The dimensions are approximately the same as the outer diameter and width of the flange portion 2. Further, an O-ring storage portion 10 having a step portion 9 and having a smaller diameter than the flange coupling portion 8 is provided inside the O-ring storage portion 10 . Furthermore, inside it is the small diameter pipe 1.
A fitting part 11 having the same diameter as the outer diameter of the fitting part 3 of
is formed.

である。 When the connection between the pipe 1 and the block 5 is completed, the plurality of caulking claws 13 are used to connect the block 5
The flange joint part 8 is removed from the step part 9 by a dimension l, and the open end side is caulked. By this caulking, a plurality of caulked portions 14 (eight recesses in this embodiment) are formed in the flange joint portion 8, and approximately the same number of flange portions 2 of the pipe 1 as the caulked portions 14 are formed.
Deformation (concavity) occurs. Since the caulking work is performed by excluding the step portion 9 or 2a by a dimension l, an annular protrusion 15 is also formed on the flange portion 2, and a plurality of caulking portions ( A recessed portion) 16 is formed respectively.
