The counter member 10 includes a front member 2 disposed on the front surface 10a side and a back member 3 disposed on the back surface 10b side of the counter 10. The front side member 2 has a flange portion 2 a having an outer diameter slightly larger than the hole diameter of the opening 11, and a tube having an outer diameter slightly smaller than the hole diameter of the opening 11 and having a female screw N formed on an inner peripheral surface. A screw receiving portion 2b having a downwardly inclined surface is formed in a lower portion of the flange portion 2a. On the other hand, the back side member 3 includes a main body 3a screwed into the cylindrical portion 2c of the front side member 2, and a locking portion 3b protruding at an opposing position on the outer surface of the lower end of the main body 3a. On the outer peripheral surface of the main body 3a, a male screw B to be screwed with the female screw N of the cylindrical portion 2c of the front member 2 is formed. The locking portion 3b has an opening 1 of the counter 10 having a length between both ends.
1 is slightly longer than the hole diameter, and the width is set to be sufficiently smaller than the hole diameter.

In order to attach the faucet 20 to the counter 10, first, the fixture 1 is attached to the opening 11 of the counter 10. This operation is performed as shown in FIG.
By inserting the fixture 1 in a state in which the back member 3 is screwed into the counter opening 11 in an appropriately inclined posture, the locking portion 3b of the back member 3 is passed through the opening 11 and It is arranged on the back surface 10b side. Thereafter, the front side member 2 and / or the back side member 3 are rotated to advance the screwing state of the two, and the counter 10 is held between the flange portion 2a of the front side member 2 and the locking portion 3b of the back side member 3. Then, the fixture 1 can be mounted on the counter 10.

When the fixture 1 is attached to the opening 11 of the counter 10, as shown in FIG. 3, a water supply pipe previously connected to a pipe connection portion 24 provided on the lower surface of the faucet 20 by brazing or the like. 40 (hot water supply pipe 41) is inserted into the hollow through portion 1 a of the fixture 1, and the faucet base 21 is placed on the counter surface 10.

And the like are provided with two openings 11 for inserting the water supply pipe 40 and the hot water supply pipe 41 in the attachment part. However, the present invention provides a water supply pipe and a hot water supply pipe in the attachment part. The present invention is also applicable to a case where only one opening 11 for both is provided. In this case, the faucet is attached using only one fixture 1. In addition, when the number of the fixing tools 1 is one, the number of use of the set screw 30 may be only one, but it does not prevent that the fixing state is strengthened by using two or more screws.

Further, the structure of the fixture 1 is different from that described above in that a male screw B is provided on the front member 2 and a female screw N is provided on the back member 3 so that the front member 2 is screwed into the back member 3. May be changed. However, considering the easiness of arranging the locking portion 3b of the back member 3 on the back surface 10b side of the counter 10 through the opening 11, as shown in the illustrated embodiment,
It is considered preferable to adopt a structure in which a female screw N is provided on the front member 2 and a male screw B is provided on the back member 3, and the back member 3 is screwed into the front member 2.

Although the fixing device 1 is configured to be mounted on the counter 10 only by working from the front side, if the work on the counter back surface 10b side can be easily performed by a single operator. For example, the work may be performed on both front and back sides of the counter 10 and the fixture 1 may be mounted.

The mounting structure according to the present invention can be applied not only to a counter, but also to a case where a water faucet is directly mounted on a basin, a bathtub, a sink, or the like.
In addition, specific embodiments of the present invention do not prevent appropriate changes and applications according to the implementation situation.
