Thus, when the operator inserts the insertion portion U of the faucet main body 12 into the through hole 23a in the cylindrical portion 23, the lower end of the insertion portion U is formed by the elastic arm portion 40c having the annular portion 40g. The elastic arm portion 40c rides on the outer peripheral surface of the lower end of the insertion portion U, slides on the outer peripheral surface of the lower end, and is fitted into the annular concave portion 16 so as to push and open the fastening member 40 away from the annular concave portion 16. Conversely, when the operator pulls out the insertion portion U of the faucet main body 12 from the through hole 23a in the cylindrical portion 23, the bent both ends of the projecting piece 40d and the projecting piece 40e are When the user holds the fingertip of the worker and applies a force so as to approach each other, the elastic arm portion 40c is moved to the annular portion 40g.
Therefore, the lower part of the insertion portion U may be pulled out from the through hole 23a in the cylindrical portion 23 in this state.

A part of the outer periphery of the fastening member 40 is provided with, for example, a protruding piece 41 which is cut and bent inward as a position shift preventing part. At the lower portion of the portion 23, for example, a circular mounting hole 42 is provided as a displacement prevention engagement portion that engages with the displacement prevention portion (see FIGS. 7 and 8).
That is, the protruding piece 41 of the fastening member 40 is fitted into the mounting hole 42 provided at the lower part of the cylindrical portion 23. Thereby, when the lower part of the insertion part U of the faucet main body 12 is inserted through the through hole 23a of the cylindrical part 23, even if the lower part of the insertion part U pushes the fastening member 40 downward, the fastening member 40 No displacement occurs. Therefore, unlike the first embodiment, it is not necessary to form the threaded portion P below the concave portion 23b of the cylindrical portion 23. However, the displacement prevention part and the displacement prevention engagement part are not necessarily
1 and the mounting hole 42 need not be provided, and may have other configurations.

As shown in FIG. 10, the inner surface of the curved portion Y has 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 of the faucet main body 12 is inserted from above into the fastening member 40 fitted into the third concave portion 23b, the insertion becomes easy. Similarly, with respect to the fastening member 32 of the first embodiment shown in FIG. 3, the inner surface of the curved portion Q is preferably formed to have an inclined surface such that the fastening width R1 becomes narrower from above to below. preferable.

Further, the faucet attached by the fixture 21 is not limited to a mixed faucet, but may be a single faucet provided with only a water supply pipe or only a hot water supply pipe. Also, the mounting fixture 21
Thus, the attachment of the washing main body 12 to the attachment hole 11 of the attachment portion such as the top plate 10 is not limited to the faucet main body 12. For example, in a water discharge facility in which mixed water or the like sent from the faucet main body 12 can be spouted from a separate shower head from the faucet main body 12, the shower head is separated from the faucet main body 12 and the ceiling water is removed. In order to hold on the plate portion 10 or the like, another flushing device such as a shower head holder attached to the attachment hole 11 of the attachment portion such as the top plate portion 10 may be attached by the attachment 21.
