参照）。By the way, conventionally, the following means can be mentioned as a method for connecting the resin pipe to the metal valve. First, the method of connecting the resin pipe through the mechanical joint connected to the connection port of the metal valve, and the joint fitting in which the mechanical joint and the heat-sealing joint are integrally joined. A method in which the connection port is connected by screw connection or flange connection, and the resin pipe is fused and attached to the heat fusion joint side, and other fittings consisting of a mechanical joint and a resin pipe are used. There is known a method of connecting a resin pipe with an adhesive agent. In addition, a method has also been proposed in which a resistance heating wire is embedded in a connection port of a synthetic resin valve box and the embedded portion and a resin pipe are fused (see Japanese Utility Model Laid-Open No. 1-131074).

接続方法の開発が強く要望されていた。However, among the above-mentioned means, the method of connecting through a mechanical joint not only requires a joint component, but also increases the number of working steps and causes rattling during use. If the pipe is pulled out or pulled out, the joint may loosen, which may cause leakage. In addition, a joint tool consisting of a mechanical joint and a heat fusion joint requires a step of connecting the mechanical joint and the valve in addition to the step of fusion with the resin pipe, which leads to an increase in cost due to an increase in the number of parts. Therefore, there has been a strong demand for the development of a connection method that solves this problem.

属体と樹脂材との接合については課題を有していた。Further, when the resin heat-sealing joint 2 having the heating element 3 of the fitting 1 shown in FIG. 4 and the metal joint body 4 are joined together, in the case of a joint having a relatively small nominal diameter, they are integrated. Although it is easy to mold, in the case of the fitting 1 having a large nominal diameter, the thickness of the tubular portion of the heat-sealing joint 2 and the joint body 4 becomes thicker, and the resin shrinks after the integral molding. Due to the strain, there is a technical problem such as a decrease in the adhesion performance of the bonded portion as shown in FIG. 4, and therefore there is a problem in bonding the metal body having a large nominal diameter and the resin material.

Therefore, parts such as metal packing cases that are not subject to thermal deformation are required, which not only complicates the structure but also increases the cost, which poses a problem in terms of economic value.
