管用継手。[Claims for Utility Model Registration] (1) A resin socket having the push nut attached to its outer periphery by screwing together a metal socket body having a female thread on the inner surface and a metal push nut having a male thread on the outer surface. In a joint for a resin pipe in which a locking part at the tip of a made shim is held and fixed between the socket body and the push nut, the inside diameter of the shim is approximately the same as the inner diameter of the resin pipe to be joined to the socket body and the rear end of the shim. By expanding the diameter of the connecting part with the resin pipe at the rear end of the Shimoku, a recess with a small outer diameter is formed between the locking part at the tip of the Shimoku and the connecting part at the rear end, and the inside of the recess is A joint for a resin pipe, characterized in that the push nut is attached to the joint. (2) The shimoku and the push nut are characterized in that the shimok is integrally molded inside the push nut by injection molding, and the two are separated by utilizing a difference in their linear expansion coefficients. Fittings for resin pipes as described.
