This completes the installation work at the installation site.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and various modifications can be made. For example, as a second embodiment, the lower portion of the tubular portion 23 of the attachment body H shown in FIGS. 7 and 8 is provided with only one cutout portion 25 as described above, and As shown in FIG. 9, the shape of the tightening member 40 of the second embodiment is a deformed ring shape in which the tightening width R1 can be widened, but unlike the first embodiment, the tubular portion 23 is different. Only one place of the annular recess 16 of the insertion portion U is fastened via the one notch 25. That is, as shown in FIG. 9, the fastening member 40 includes an annular portion 40a, an elastic arm portion 40c, a narrow protruding portion 40d, and a protruding portion 40e having a long hole G formed therein. These are the same as the annular portion 32a of the first embodiment, the elastic arm portion 32c, the narrow protruding portion 32d, and the protruding portion 32e in which the elongated hole G is formed, respectively. Although it has a shape (see FIGS. 3 and 6), the shape of the elastic arm portion 32b of the first embodiment is different in that it is an annular portion 40g in the second embodiment.

The annular portion 40a, the annular portion 40g, the narrow protruding portion 40d, and the protruding portion 40e having the elongated hole G are formed so as to extend along the outer periphery of the recess 23b of the tubular portion 23. While bending, the projecting piece portion 40d is passed through the elongated hole G. Accordingly, similarly to the first embodiment, when the operator or the like holds the bent end portions of the protruding piece 40d and the protruding piece 40e and applies a force so that they approach each other. , The elastic arm portion 40c moves away from the annular portion 40g so as not to tighten the annular concave portion 16 of the insertion portion U 1, and when the force applied by the operator or the like is removed, The elastic arm 40c moves closer to the annular portion 40g so as to tighten the annular recess 16.

In addition, a curved portion Y 1 that is curved so as to project outward is formed in the center of the elastic arm portion 40c, and the curved portion Y 1 is formed on the outer peripheral portion of the inserted portion U. Tighten the outer periphery so that it follows. The annular recess 16 of the insertion portion U is a cutout of the tubular portion 23 with the insertion portion U of the faucet body 12 inserted into the through hole 23a in the tubular portion 23, as in the first embodiment. Since it is formed so as to be located at the position of the portion 25 and the position of the concave portion 23b of the tubular portion 23, the tightening member 40 fitted in the concave portion 23b of the tubular portion 23 is inserted through the notch portion 25 of the tubular portion 23. By being fitted into the annular recess 16, the annular recess 16 can be tightened and fixed.

As a result, when the operator inserts the insertion portion U of the faucet body 12 into the through hole 23a in the cylindrical portion 23, the elastic arm portion 40c has an annular portion 40g at the lower end of the insertion portion U. The elastic arm portion 40c rides on the lower end outer peripheral surface of the insertion portion U, slides on the lower end outer peripheral surface thereof, and is fitted into the annular recess 16 in order to push the tightening member 40 apart so as to be separated from the elastic arm portion 40c. . On the contrary, when the worker pulls out the insertion portion U of the faucet body 12 from the through hole 23a in the tubular portion 23, the bent tip ends of the protruding piece portion 40d and the protruding piece portion 40e are When the operator holds the fingertips and applies a force so as to bring them closer to each other, the elastic arm portion 40c moves away from the annular portion 40g, so that the lower portion of the insertion portion U is kept in that state. It may be pulled out from the through hole 23a in the cylindrical portion 23.

In addition, as a position deviation prevention portion, for example, a protruding piece 41 that is cut and bent inward is provided on a part of the outer periphery of the fastening member 40. A circular mounting hole 42, for example, is provided in the lower portion of the cylindrical portion 23 as a displacement prevention engagement portion that engages with the displacement prevention portion (see FIGS. 7 and 8). That is, the projecting piece 41 of the tightening member 40 is fitted into the mounting hole 42 provided in the lower portion of the tubular portion 23. Thereby, when the lower part of the insertion part U of the faucet device 12 is inserted through the through hole 23a of the tubular part 23, even if the lower part of the insertion part U pushes the tightening member 40 downward, No displacement occurs. Therefore, unlike the first embodiment, it is not necessary to form the threaded portion P below the recess 23b of the tubular portion 23. However, the position shift prevention portion and the position shift prevention engagement portion do not necessarily have to be configured by the projecting piece 41 and the mounting hole 42, and may be configured by other configurations.

As shown in FIG. 10, the inner surface of the curved portion Y is an inclined surface such that the tightening width R1 becomes narrower from the upper side to the lower side. When the lower end of the insertion portion U 1 of the water faucet body 12 is inserted from above from the upper portion of the fastening member 40 fitted in the recess 23b of 23, the insertion is facilitated. Also in the tightening member 32 of the first embodiment shown in FIG. 3, similarly, the inner side surface of the curved portion Q should be an inclined surface such that the tightening width R1 becomes narrower from the upper side to the lower side. preferable.

Further, the faucet attached by the fitting 21 is not limited to the mixed faucet, and may be a single faucet having only a water supply pipe or only a hot water supply pipe. Further, it is not limited to the faucet body 12 that the flush body 12 can be attached to the attachment hole 11 of the attachment portion such as the top plate portion 10 by the attachment tool 21. For example, in a water discharge facility in which mixed water or the like sent from the faucet body 12 can be discharged from a shower head separate from the faucet body 12, the shower head is separated from the faucet body 12 to a ceiling. In order to hold it on the plate portion 10 or the like, other washing equipment such as a shower head holder attached to the attachment hole 11 of the attachment portion of the top plate portion 10 or the like may be attached by the attachment tool 21.
