This mounting structure is not limited to the single faucet of the present embodiment, and can be applied to various types of faucets with walls. Next, this mounting structure will be described.

In general, when the main body of the water faucet is attached to the wall surface via a stay, fixing means by screwing is adopted. However, many screwing operations are required, and many screws are exposed. The beauty is reduced. On the other hand, in this example, a stay having a hook piece on the upper part is attached to the wall in advance, and the main body is hooked on the stay, and the main body is fixed separately from the hook by fixing means such as screwing or bonding. Is firmly fixed to the wall. This simplifies the fixing work without having to perform many screwing operations,
Many screws are not exposed, and the beauty is improved. This will be described in detail below.

As shown in FIGS. 1 to 3, a stay 81 is arranged on the front side of the wall surface 80, and a mounting plate 83 is arranged on the back side. A female screw is provided on the mounting plate 83, and a screw 84 is screwed onto the female screw from the front side of the stay 81, so that the stay 81 and the mounting plate 83 form a wall surface 80.

The main body 10 has an opening 20 on the back surface, and the upper part of the opening 20 is hooked on the hook piece 82. Then, a fixing screw 85 is screwed onto the female screw of the stay 81 from the front side of the main body 10, and the main body 10 is firmly fixed to the wall surface 80 with the fixing screw 85. In addition, fixing screw 8
5 may be screwed from the lower surface side or the side surface side of the main body 10. Further, the fixing screw 85 is not limited to being screwed to the stay 81, but may be screwed directly to the wall surface 80, or may be screwed to a separate member (not shown) attached to the wall surface 80. Further, the fixing means firmly fixed to the wall surface 80 of the main body 10 is not limited to the fixing screw 85, and various fixing means such as adhesion can be adopted.

In the single faucet of this embodiment, a spout is rotatably mounted on the main body. The mounting structure of the spout is also novel and can be applied not only to the single faucet of this example, but also to a wide variety of faucets. Next, the mounting structure of the spout will be described.

As shown in FIG. 1, the discharge chamber 13 is
The inside of the supply chamber 11 is drawn forward from the side of the supply chamber 11 and the upper part is open. This open part is the mounting part 21 of the spout 70. Specifically, the mounting unit 21
Is formed in a cylindrical shape, and a cylindrical water outlet 70 is rotatably inserted into the mounting portion 21. A stop bolt 71 is screwed onto the main body 10 from above the water outlet 70, and the stop bolt 71 prevents the water outlet 70 from being pulled out of the mounting portion 21. In this example, the mounting portion 21 side is a female side, and the water outlet 70 side is a male side.
The 0 side may be the female side. Further, the means for preventing the water outlet 70 from being pulled out is not limited to the above-mentioned stop bolt 71. further,
The water outlet 70 may be disposed at an appropriate portion such as below or on the side of the main body 10.

The water outlet 70 is rotatably and watertightly connected to the main body 10. Here, in order to secure both the rotation operability and the water tightness, one or a plurality of sealing members such as O-rings are conventionally interposed between the water outlet 70 and the mounting portion 21. Has been done. In such a structure, smooth rotation operability is impaired when trying to obtain sufficient watertightness, and sufficient watertightness is impaired when trying to obtain smooth rotation operability. Therefore, in this example, a seal member 72 such as an X-packing, a U-packing, or a V-packing, which has a bag-shaped portion that is in close contact with a member that is made watertight when subjected to fluid pressure, is different in form from the sealing member 72. An elastic member 73, such as an O-ring or a plate-like packing, for example, is provided between the water discharge port 70 and the mounting portion 21 to prevent rattling between members that are appropriately elastically deformed and rotate and that are rotatable. In such a structure, sufficient watertightness is ensured by the seal member 72, and sufficient rotation operability is ensured by the elastic member 73.

In this embodiment, the elastic member 73 is disposed on the inner side of the inserted portion of the members to be inserted into each other to further prevent rattling. Further, a member having a sealing function is adopted as the elastic member 73, and the watertightness of the sealing member 72 is further improved. Here, by disposing the elastic member 73 on the back side of the inserted portion, the elastic member 73 functions as a first sealing member, and the sealing member 72 having more excellent watertightness is used as a second sealing member. Functions as a member. Therefore, even if water leaks from the elastic member 73 as the primary seal member, the water leak is reliably sealed by the secondary seal member 72. Thereby, the reliability can be improved.
