特徴とする伸縮継手。 A pipe is inserted into a socket at least at one end of a cylindrical joint body, and an annular elastic seal member is disposed between the pipe and the joint body to seal the space between them. Pressure is applied by a push ring screwed onto one end of the main body, and the pressure is applied between the push ring and a tapered portion formed on the inner circumferential surface of the joint body, and the clamping pressure creates a predetermined distance between the joint body and the pipe. A joint that is sealed with a sealing force of , and is further provided with an expandable and retractable retaining member for preventing the pipe from being pulled out between the pipe and the push ring, and the retaining member is axially moved along with the pipe to the inner circumference of the push ring. A straight part having a uniform diameter is formed, and a withdrawal movement regulating part is formed that reduces the diameter of the retaining member and bites into the pipe when moving from the outer end of the straight part in the direction of pulling out the pipe. expansion joint.
