6,157 are attached.

As shown in FIG. 1, the hot and cold water mixing faucet 120 includes operating shafts 121 and 122 and water passage cylinders 127 and 1.
Since it is provided so as not to be in line with 28, the valve portion can be configured to be thin with a short depth without overlapping with the water flow tube portions 127 and 128, and between the narrow panel 100 and the fixing bracket 115. Can be stored. In addition, water supply pipe joint 10
1, 102, water discharge pipe joints 109 and 110, respectively, when water passage cylinders 127 and 128, water discharge pipe 131, and short pipe 135 are inserted through the O-rings 160 provided in the pipe joints.
Since the outer peripheral surface is sealed by the seal member 159 in the cap nut, the gap between the wall panel 100 and the faucet 120 or the wall panel 100 and the water discharge head 13 is provided.
Even if there is a variation in the distance from 3, the watertight sealing property will not deteriorate.

A fixing member 115 is fixed to the wall panel 100, and the fixing member 115 has a faucet 120 and a water discharge head 13.
Since 3 and the like are fixed, the counter panel 150 does not need strength to support them, so that the counter panel 150 can be made relatively thin with plastic and the cost of the members can be reduced. And the counter panel 15
0 can be easily removed by loosening the fixing nuts 154, 155, and 158, and the faucet 120 and the pipes on the back surface thereof can be easily inspected, which facilitates maintenance.

In this embodiment, the case of a two-valve type hot and cold water mixing tap has been described.
It is also possible to install a single lever type mixed faucet or a single faucet. Further, although this embodiment has described the faucet for supplying hot water to the bathtub of the unit bath, it can also be applied to a faucet in a bathroom, a faucet in a vanity, a kitchen, or the like.

[0014]

As described above, the faucet mounting structure of the present invention is
Since the water passage cylinder part on the primary side of the faucet body is directly inserted into the water supply pipe joint that is inserted through the wall panel to connect it, the space between the wall panel and the counter panel can be narrowed and space can be saved. Therefore, there is an advantage that it is possible to reduce the amount of protrusion to the room compared to the conventional one, and since the faucet body is supported by the wall panel through the fixing metal fittings, the counter panel does not have a heavy load and needs strength. Since it does not, there is an advantage that the manufacturing cost can be reduced.
