<p><P>PROBLEM TO BE SOLVED: To provide a pipe fitting made of synthetic resin having a simple structure in connection with a synthetic resin pipe by TS construction method and allowing insertion of the pipe fitting but not allowing movement in a removal direction in connection. <P>SOLUTION: In the pipe fitting made of synthetic resin having a spigot inserted/connected to an opening of the synthetic resin pipe through an adhesive, the spigot is provided with a tapered surface enlarged in diameter from a distal end toward a rear end and inserted/connected to the opening having an inner diameter larger than an outer diameter of the distal end and smaller than an outer diameter of the rear end. Further, on a rear end of the tapered surface, a corner part allowing insertion of the spigot but not allowing its movement in a removal direction by biting it into an inner peripheral surface of the opening swelled by coating of the adhesive in connection is formed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
