<p><P>PROBLEM TO BE SOLVED: To prevent displacement of a packing during a connecting operation by holding the packing on a piping resin joint side in a resin joint for piping having a corrugated pipe coated inside. <P>SOLUTION: A connection flange part 3 is attached to an end of a corrugated pipe 1 having an internal coated resin layer 2. A face plate part 13 extends to an end of the corrugated pipe 1 inserted through the connection flange part 3. An additional coated resin layer 21 formed by extending the internal coated resin layer 2 is overlaid to the face plate part 13. A packing 5 integrally has a packing main part 51 overlaid on the outside of the face plate part 13, and an attachment piece part 52 extending from the packing main part 51 in a folded fashion, and overlaid to the inside of the face plate part 13. The packing main part 51 and the attachment piece part 52 are arranged astride the face plate part 13, so that the packing 5 is held by the face plate part 13. <P>COPYRIGHT: (C)2004,JPO</p> |
