<p>The present invention relates to a pipe joint made of resin. A joint body 1 is provided with a receiving port 11, a cylindrical portion 12 and an annular groove portion 13, and an inner ring 3 inserted by a pushing ring 5 is provided with a cylindrical projection 34, a projection 34 of the inner ring 3 is divided into a guiding portion 3A having a guiding surface 37 inclining in a state of widening toward the tip thereof, on a side of an inner periphery thereof and an effective length portion 3B having no guiding surface 37. According to the present invention, a sealing surface pressure is generated to both axial and radial directions, thereby making it possible to keep an efficient sealing property for a long time, at the same time facilitating a control of a fastening torque of the pushing ring 5. <IMAGE></p> |
