Description of the Related Art When a faucet is mounted on a faucet mounting hole such as a counter or a basin flange, the faucet is arranged behind a sink or a basin, so that the faucet is fixed (for example, nuts are tightened). Is performed in the rear part of the sink or basin, and the fixing work posture is difficult and workability is poor. In addition, a special crank-shaped special tool for tightening nuts while bypassing a sink or a basin is required.

[0003] In view of the above, various structures have been proposed for fixing a faucet to a faucet mounting hole of a faucet installation plate such as a counter or a basin flange simply by working from above.

As one of them, an annular pedestal member is disposed above a faucet mounting hole of a counter or the like, a mounting member is disposed below a faucet mounting hole, and a bolt is inserted into a base hole of the pedestal member from above. A structure is known in which the bolt is screwed into a female screw hole of the mounting member, the mounting member is pulled upward, the pedestal member is fixed to the counter or the like, and a water faucet is fixed to the pedestal member (Japanese Patent Laid-open No. 8-93012).

[0005] Figs. 10 to 12 are perspective views showing the structure of the same publication.
2) is bored, and an annular pedestal member 63 is disposed on the upper side thereof. A horseshoe-shaped member 64 is provided below the faucet mounting hole 61.
