Claims

[Scope of utility model registration request]

a joint main body having a gasket accommodating portion at an open end; an annular gasket accommodated in the gasket housing; an annular retainer that abuts the outer end surface of the gasket; A cylindrical press ring that presses by screwing into the inner peripheral surface of the opening and has a first tapered surface that gradually approaches the inner peripheral surface in the axial direction and a straight surface that is parallel to the axial direction; It has a cut annular shape fitted between the circumferential surface and the outer circumferential surface of the tubular body, and slides on the outer circumferential surface while being in contact with the tapered surface that is pressed against the first tapered surface of the press ring and the straight surface of the press ring. having a parallel portion, and having an edge on the inner circumferential surface that bites into the outer circumferential surface of the tube body,
The pipe joint further includes a retaining ring having a notched step at the rear end of the edge to form a tilting regulating section.
