ようにした手段である。As means for manufacturing an outer cylinder which is a main part of the body of the automatic mixing faucet, Japanese Patent Application Laid-Open No. 6-307567 is used.
There is a means in the gazette. In this means, the outer cylinder is formed of a metal pipe, and the inner cylinder for storing the mixing valve unit is formed by molding with a synthetic resin material and fitted therein.
A jacket formed between the outer peripheral surface of the inner cylinder and the inner peripheral surface of the outer cylinder is partitioned by a partition member that is formed into a partition wall shape on the outer peripheral surface of the inner cylinder. A watertight holding member is interposed between the outer end surface of the member and the inner peripheral surface of the outer cylinder, so that the hot water flow path, the water flow path, and the mixed water flow path are separated in a watertight manner from the jacket. This is a means in which a fitting metal fitting formed inside and communicating with these flow paths is provided in the outer cylinder, and a hot water supply pipe, a water supply pipe, and a pipe for taking out mixed water are connected to the fitting fitting.

水密の保持がむづかしくなる問題が生じてくる。However, in the means disclosed in Japanese Patent Application Laid-Open No. 6-307567, a jacket formed between the outer cylinder and the inner cylinder is partitioned by a partition member provided on the outer peripheral surface of the inner cylinder in a partition wall shape. When forming a plurality of flow paths, the partition member,
By forming a shape along the axial direction of the inner cylinder and providing it in parallel at a predetermined interval in the circumferential direction of the inner cylinder, the jacket can also be partitioned in the circumferential direction. Although it becomes possible to divide the flow passage into a number of flow passages, each of the flow passages formed by the partition wall members is water-tight by a water-tight holding member interposed between the outer edge of the partition wall member and the inner peripheral surface of the outer cylinder. As a result, there is a problem that the assembly of the watertight member becomes troublesome. Also, it is difficult to insert the inner cylinder incorporating the mixing valve unit into the outer cylinder and assemble and fix it to the outer cylinder, especially a joint provided on the outer peripheral surface of the outer cylinder. It is difficult to position the metal fittings and each flow path in a state where they are properly communicated, and it is difficult to assemble and fix the inner cylinder to the outer cylinder. If it is made to protrude outside from the through hole provided in the outer cylinder, the work becomes troublesome, and furthermore, it becomes difficult to maintain the watertightness of the connection portion.
