PROBLEM TO BE SOLVED: To enhance the efficiency of the insertion work of a pipe member by mainly optimizing a structure and a shape.SOLUTION: A telescopic joint 1 integrally has a spigot part 3 and a socket part 4 which is larger than the spigot part 3 in diameter, and can absorb the thermal elongation/contraction of a pipe member 5 which is inserted therein from the socket 4. In the telescopic joint 1, the socket part 4 has, therein, a seal part 11 which elastically contacts with an external peripheral face of the inserted pipe member 5, and can perform sealing to the displacement of the pipe member 5 to an axial line direction 8 and a radial direction 9, the spigot part 3 has a final position regulation part 12 at the inside of the spigot part 3 which regulates its position so that an end part of the inserted pipe member 5 does not intrude into the spigot part 3 or deeper, and an intermediate stop part 13 which can stop the end part of the pipe member 5 at an optimum insertion depth is arranged at a position at this side by a maximum elongation amount of the pipe member 5 from the final position regulation part 12 at the inside of the spigot 3.
【課題】主に、構造や形状を最適化して管部材の挿入作業を効率化し得るようにする。【解決手段】差口部３と、差口部３よりも径の大きい受口部４とを一体に有すると共に、受口部４から内部へ挿入された管部材５の熱伸縮を吸収可能な伸縮継手１である。この伸縮継手１は、受口部４が、その内部に、挿入された管部材５の外周面に弾接して、管部材５の軸線方向８および半径方向９への変位に対するシールが可能なシール部１１を有し、差口部３が、その端縁部の内部に、差口部３まで挿入された管部材５の端部がそれ以上奥へ入り込めないように位置規制する最終位置規制部１２を有すると共に、差口部３の内部における最終位置規制部１２よりも管部材５の最大熱伸長量分だけ手前側の位置に、管部材５の端部を最適挿入深さで停止可能な中間停止部１３を設けるようにしている。【選択図】図２
