But outside As long as the inner diameter of the side housing 201 is smaller than the inner diameter, there is no particular restriction on the degree of the compression deformation.
- the fastening jig removed from the inner housing 202 after the sealing member 205 freezes. Since the fixture 211 has been cooled to a remarkable temperature, the moisture in the air will freeze and adhere to the surface of the fastening jig 211 as frost. There is power. For this reason, when attaching the new inner housing 202 and compressing and deforming the seal member 205, unzip and dry the fastening jig 211. It is better to let them do so. Alternatively, the entire work chamber may be kept below freezing to keep the air dry, or a dry air may be used to open the air, so that the fastening jig 2 1 1 It is preferred that frost does not adhere to the surface.

- the injected liquid seal material 235 runs through the entire groove as shown in FIG. 45 because the concave groove 230 of the seal holding portion 227 is continuous. After passing, it reaches the other inlet, 23 3.
- the hot water mixing device is then carried into a thermostat and heated for a predetermined time.
- the liquid seal material 235 is hardened in a rubber-like manner, and the water passages 228 and 229 are reliably sealed.
- the liquid seal material 235 also penetrates into the gap between the inner surface of the outer housing 225 and the seal holding portion 227. Therefore, the sealing is performed in a wider width than the conventional solid packing. With this power, a reliable seal without hot water or water leakage due to water pressure can be obtained.
- the liquid sealant 235 it is preferable to use a silicon-based material which is not easily hydrolyzed even when it comes in contact with hot water.
- At least at least two of the two primary water holes formed through the inner housing communicate with the hot water supply path.
- Water and secondary water holes The inner housing and the outer housing are surrounded by an isolating member that is disposed so that the part intersects the circumferential line of the inner housing. Since the required fluid passage is formed in the space between the housing and the housing, the hot water is isolated in a predetermined area, for example, a narrow area, and the inner housing becomes hot. That water or air could be placed over a wide area to surround the outer perimeter of the inner housing. In particular, such a configuration can be easily obtained without forming a special passage in the inner housing.
- the secondary water passage hole communicating with the mixed water discharge passage is disposed so that a part of the water passage hole intersects the circumferential line of the inner housing. Since it is installed and surrounded by the isolation member, it is possible to form the secondary side water holes and surrounding area large in the axial direction of the inner housing. Wear . Therefore, the placement position of the call, the hose for the shower, etc. connected to this surrounding area should be selected with great freedom in the axial direction. I can do it.
- the area surrounded by the isolation member can be formed large in the axial direction of the inner housing, so that the inner housing can be formed. O It is relatively easy to adjust the misalignment of the holes drilled in the outer housing and the outer housing, respectively.
- the location of the isolation member, its configuration, the number of perforated water holes, the perforated shape, and the like are changed. This makes it possible to easily configure an optimal water / water mixing device according to the intended use and use conditions.
