<P>PROBLEM TO BE SOLVED: To positively prevent falling out from a joint main body without letting the pressure of a fluid act on especially an insertion port end face of a pipe body. <P>SOLUTION: The pipe joint comprises: the cylindrical joint main body 2 having a deformable deformation part 6 which can be deformed to be reduced in diameter and an opening end side having a large diameter hole 5 is formed thin, and a small diameter hole 7 formed in the back continuing from the large diameter hole 5, and sets the bore diameter of the large diameter hole 5 to be the same as the outer diameter of the pipe body 1 and the bore diameter of the small diameter hole 7 to be the same as the inner diameter of the pipe body 1 or somewhat smaller; and a seal material 3 formed into a cylinder with the outer diameter and the inner diameter the same as the large diameter hole 5 of the joint main body 2 and the bore diameter of the small diameter hole 6, respectively, and interposed between the insertion port end face 1a of the pipe body 1 and a small diameter hole end face 7a of the joint main body 2. The deformation part 6 is deformed to be reduced in diameter so that it is narrower toward the tip end by sliding pressure contact of the outer diameter of the deformation part 6 from the tip end toward the base end. <P>COPYRIGHT: (C)2007,JPO&INPIT |
