<p>PROBLEM TO BE SOLVED: To provide a pipe joint capable of preventing slip-off due to expansion and contraction of a pipe to be connected, and absorbing bending of the pipe to be connected in a joint part. SOLUTION: A joint body 1 is formed by a short cylinder 2 having a female screw part 11, and a fixing member 3 to which the other end opening part of the short cylinder is connected through a stopping means 5. The pipe joint is provided with a cylindrical retainer 4 having a male screw part 13 engaged with a tapered female screw part 11 and a parallel female screw part 12 of the short cylinder 2 and a plurality of pipe stopping small disks 6 buried along the thread ridge of the male screw part 13. A pull-out margin void part 32 is formed inside the fixing member 3, and a pipe rush-in margin void part 33 is formed between the inner end of the retainer 4 and the outer end of the fixing member 3 so that the tip part 47 of the pipe 7 to be connected is inserted deeply enough inside a sealing material 8 rather closer to the tip of the fixing member 3 to be connected.</p> |
