Claims

[Scope of utility model registration request]

A joint body, a connecting pipe fitted into the joint body, and a connecting pipe fitted on the outer periphery of the connecting pipe, one end of which is in contact with the end face of the joint body, and a diameter tapered toward the other end of the outer periphery. an elastic ring body formed with a tapered surface; a cap nut into which the connecting pipe is inserted and which has a tapered surface parallel to the tapered surface of the elastic ring body on its inner surface and is screwed onto the joint body;
A slide made of synthetic resin, which is interposed between the tapered surface of the elastic ring and the tapered surface of the cap nut, and has a plurality of slotted grooves whose diameter decreases toward the tip and is cut from the distal end to near the proximal end. An annular step formed on the outer periphery of the base end of the elastic ring body is engaged with the base end of the sliding ring body, and the tip of the elastic ring body is engaged with an annular projection formed on the inner periphery of the tip end. An expansion joint characterized in that the inner circumferential edge of the annular projection is formed into an edge shape that engages with the outer circumference of the connecting pipe.
