る。The faucet main body 3 has the center line C of the main body because of the connection of the water supply pipe 8 and the hot water supply pipe 9.
Therefore, the bolt 4 needs to be provided so as to be eccentric by the dimension E. Therefore, when the nut 3 is clamped in the seat portion 3a of the faucet body 3 by the tensile force P generated in the bolt 4,
An eccentric tensile force P of the bolt 4 causes a couple moment M (M = PxE) in the arrow A direction on the center line C of the main body.

The compressive stress may be zero. Therefore, in the packing 2, the bolt eccentric side portion 2a is largely compressed and deformed to incline the faucet body 3 to the state shown by the chain double-dashed line B, and the bolt non-eccentric side portion 2b is incompletely sealed. Water leakage may occur from the front surface 1a of the plug attachment member 1 to the back surface 1b.

Bolt, a crimp body attached to the bolt so as to abut the bottom surface of the faucet mounting member, and a nut screwed to the bolt. The crimp body and the faucet are caused by the tensile force of the bolt generated by tightening the nut. In a faucet mounting structure in which a faucet mounting member is sandwiched between a seat portion of the main body, a moment reaction force is transmitted from the crimping body to the nut, so that the tensile force of the bolt causes the reaction to occur in the seat portion of the faucet body. This is to generate a couple moment in the bolt itself in a direction opposite to the rotating direction of the couple moment.

The difference from the first embodiment shown in FIG. 8 is that the operating point region of the crimping body 35 which receives the tightening force of the nut 6 is formed by the projecting portion 35a which is projectingly biased toward the center line C side of the faucet body 3. It is a point. The protruding portion 35a is formed by cutting and raising, welding, or the like. The nut 6 has a flange portion 6b formed at the upper end so as to surely contact the protrusion 35a of the crimp body 35. In the present embodiment, the configuration other than this difference is substantially the same as that of the first embodiment.

る。Since the projection 35a of the crimping body 35 and the center of the bolt 4 are separated by the dimension F, the bolt 4 itself has
A couple moment N (N = PxF) is generated by the tensile force P generated on the bolt 4 by tightening the nut 6. Since the couple moment N is in a rotation direction opposite to the rotation direction of the couple moment M generated in the seat portion 3a of the water faucet body 3 due to the tension of the bolt 4, the couple moment M is relaxed.

Is small, and the difference between the compression deformations of the two parts 2a and 2b is small. As a result, the faucet body 3
Even if the couple moment M is received, the inclination becomes much smaller than in the conventional case, and it is possible to prevent a gap that causes water leakage from being formed in the bolt non-eccentric side portion 2b of the packing 2.

となる隙間を形成しないようにできる。The packing 42 is formed of a rubber or resin material, and the compression portion (water faucet body) on the eccentric side 42a from the center line C of the faucet body 3 toward the bolt 4 with the penetrating portion of the bolt 4 as a boundary. 3a and the water faucet mounting member 1) 42a-1 and a compressed portion 42b- on the opposite side 42b.
It is formed to be harder than 1 and has a large elastic coefficient related to compression. Since the packing part 42 has a large elastic coefficient of the compression part 42a-1 on the eccentric direction side 42a, even if a large compressive stress acts on the tensile force P generated by the tightening of the nut 6 and the couple moment M, the amount of compressive deformation is large.

成しないようにできる。The packing 52 has a soft portion formed of rubber or a resin material, and the eccentric direction side 52 from the center line C of the faucet body 3 toward the bolt 4 with the penetrating portion of the bolt 4 as a boundary.
By interposing a high hardness plate 53 made of a steel plate, a resin plate or the like at a proper position of the compressed part 52a-1 (the part sandwiched between the water faucet body 3 and the water faucet mounting member 1) of a, the reverse side 52
The elastic coefficient related to compression is made larger than that of the compressed portion 52b-1 of b. The packing 52 has an eccentric direction side 52a.
Since the compressive portion 52a-1 has a large elastic coefficient, the amount of compressive deformation is small even if a large compressive stress acts on the compressive portion 52a-1 due to the tensile force P and the couple moment M generated by tightening the nut 6. The amount of compressive deformation of the compressed portion 52b-1 on the opposite side 52b on which a small compressive stress acts can be made substantially equal. As a result, the faucet body 3 can be made to have an inclination due to the couple moment M of zero or much smaller than the conventional one, and the packing 52 can be prevented from forming a gap that causes water leakage.
