以下、本発明を具体化した一実施形態を図１及び図２に従って詳細に説明する。
図１に示すように、流路としての水栓継手１は、右端部に例えば屋外からの給水パイプが装着され、左端部に例えば屋内の蛇口が装着され、給水パイプからの水を内部に通して蛇口へと送る。水栓継手１は、左端部の外周面にネジ部１ａが形成され、当該ネジ部１ａよりも右端部側にフランジ部１ｂが形成されている。取付対象としての壁２には、水栓継手１の左端部が通る程度の大きさの貫通孔２ａが形成されている。 Hereinafter, an embodiment embodying the present invention will be described in detail with reference to FIGS.
As shown in FIG. 1, the faucet joint 1 as a flow path is provided with, for example, an outdoor water supply pipe at the right end, and with an indoor faucet, for example, at the left end, and passes water from the water supply pipe to the inside. To the faucet. The faucet joint 1 has a screw portion 1a formed on the outer peripheral surface of the left end portion, and a flange portion 1b formed on the right end portion side of the screw portion 1a. A through-hole 2 a having a size enough to pass the left end portion of the faucet joint 1 is formed in the wall 2 as an attachment target.

前記水栓継手１は、フランジ部１ｂが壁２の裏面に当接された状態で、左端部が壁２の貫通孔２ａを介して表面に突出される。この水栓継手１の突出部分は、流路用環状体としての円盤状をなすパッキン３、及び流路部材としての円盤状をなす座金４に対して、それぞれの中央部に形成された貫通孔３ｅ及び貫通孔４ｃへ同順に挿し通される。そして、ネジ部１ａにナット６がねじ込まれることで、ナット６とフランジ部１ｂとの間で、壁２、パッキン３及び座金４が互いに締め付けられる。   The faucet joint 1 has a left end projecting through the through-hole 2 a of the wall 2 in a state where the flange 1 b is in contact with the back surface of the wall 2. The protruding portion of the faucet joint 1 is a through-hole formed at the center of each of the packing 3 having a disk shape as an annular body for a flow path and the washer 4 having a disk shape as a flow path member. 3e and the through hole 4c are inserted in the same order. Then, when the nut 6 is screwed into the screw portion 1a, the wall 2, the packing 3, and the washer 4 are fastened to each other between the nut 6 and the flange portion 1b.

前記パッキン３及び座金４のそれぞれには、周方向に等間隔で３つのネジ孔３ａ（取付孔）及びネジ孔４ａが形成されている。取付部材としてのネジ５は、座金４のネジ孔４ａからパッキン３のネジ孔３ａに挿通され、壁２にねじ込まれてパッキン３及び座金４を壁２に固定する。   Each of the packing 3 and the washer 4 is formed with three screw holes 3a (mounting holes) and screw holes 4a at equal intervals in the circumferential direction. A screw 5 as an attachment member is inserted into the screw hole 3 a of the packing 3 from the screw hole 4 a of the washer 4 and screwed into the wall 2 to fix the packing 3 and the washer 4 to the wall 2.

前記パッキン３の材質は、合成ゴム又は合成樹脂等である。パッキン３は、壁２と座金４との間に介在される部分でありかつネジ孔３ａが形成された座部３ｄと、当該座部３ｄにおいて外周縁の一部に形成された弦状部３ｃと、当該弦状部３ｃに連結された除去予定部３ｂとを有している。座部３ｄの外周縁において、弦状部３ｃ以外の部分である円弧部３ｆの外径は、座金４の外径より若干小さい。除去予定部３ｂは、円盤状をなす操作部３ｂ−１と、当該操作部３ｂ−１を座部３ｄの弦状部３ｃに連結する、横断面積の狭い脆弱部３ｂ−２を有している。弦状部３ｃは、ネジ孔３ａに対して周方向にずれた位置、特に隣接する二つのネジ孔３ａ間の中間位置に形成されている。つまり、除去予定部３ｂは、ネジ孔３ａに対して周方向にずれた位置で、座部３ｄに連結されている。   The material of the packing 3 is synthetic rubber or synthetic resin. The packing 3 is a portion interposed between the wall 2 and the washer 4, and a seat portion 3d in which a screw hole 3a is formed, and a chord-like portion 3c formed in a part of the outer peripheral edge of the seat portion 3d. And a to-be-removed portion 3b connected to the string-like portion 3c. At the outer peripheral edge of the seat portion 3 d, the outer diameter of the arc portion 3 f that is a portion other than the chord-like portion 3 c is slightly smaller than the outer diameter of the washer 4. The to-be-removed part 3b has a disk-like operation part 3b-1 and a weak part 3b-2 having a small cross-sectional area that connects the operation part 3b-1 to the chord-like part 3c of the seat part 3d. . The string-like portion 3c is formed at a position shifted in the circumferential direction with respect to the screw hole 3a, particularly at an intermediate position between two adjacent screw holes 3a. That is, the planned removal portion 3b is connected to the seat portion 3d at a position shifted in the circumferential direction with respect to the screw hole 3a.

図２（ａ）及び図２（ｂ）は、前記水栓継手１を壁２に設置する作業の途中を示し、詳しくは、ネジ５（図１参照）がパッキン３のネジ孔３ａ及び座金４のネジ孔４ａに挿通される前でかつ、ナット６（図１参照）とフランジ部１ｂ（図１参照）との間で、壁２、パッキン３及び座金４が非常に軽く締め付けられた状態を示す。この状態でパッキン３は、座部３ｄの弦状部３ｃ及び円弧部３ｆが、壁２と座金４とが形成する間隙内に入り込んだ状態となるとともに、除去予定部３ｄの操作部３ｂ−１が当該間隙内から外方へ延出した状態となる。したがって、作業者は、操作部３ｂ−１を手掛かりとすることで、パッキン３を周方向や径方向へ容易に位置調整でき、よって当該パッキン３のネジ孔３ａを座金４のネジ孔４ａに対して容易に位置合わせできる。   2 (a) and 2 (b) show the process of installing the faucet joint 1 on the wall 2 in detail. Specifically, the screw 5 (see FIG. 1) is a screw hole 3a of the packing 3 and a washer 4. The wall 2, the packing 3 and the washer 4 are very lightly tightened before being inserted into the screw hole 4a and between the nut 6 (see FIG. 1) and the flange portion 1b (see FIG. 1). Show. In this state, the packing 3 is in a state in which the chordal portion 3c and the circular arc portion 3f of the seat portion 3d enter the gap formed by the wall 2 and the washer 4, and the operation portion 3b-1 of the planned removal portion 3d. Is extended outward from the gap. Therefore, the operator can easily adjust the position of the packing 3 in the circumferential direction and the radial direction by using the operation portion 3b-1 as a clue. Therefore, the screw hole 3a of the packing 3 can be positioned with respect to the screw hole 4a of the washer 4. Can be easily aligned.

図２（ｃ）に示すように、前記パッキン３の位置調整が完了すれば、ネジ５をパッキン３のネジ孔３ａ及び座金４のネジ孔４ａに挿通しかつ壁２にねじ込み、ナット６（図１参照）を所定まで強く締め付けた後、操作部３ｂ−１を強く引っ張ることで脆弱部３ｂ−２を破断させ、除去予定部３ｂを座部３ｄから除去する。除去予定部３ｂは、ネジ孔３ａに対して周方向にずれているため、操作部３ｂ−１を強く引っ張ることに起因したストレスが、ネジ孔３ａに作用することを抑制でき、例えばネジ孔３ａの破断を防止できる。   When the position adjustment of the packing 3 is completed as shown in FIG. 2C, the screw 5 is inserted into the screw hole 3a of the packing 3 and the screw hole 4a of the washer 4 and screwed into the wall 2, and the nut 6 (FIG. 1) is strongly tightened to a predetermined level, and then the operation portion 3b-1 is pulled strongly to break the fragile portion 3b-2 and remove the planned removal portion 3b from the seat portion 3d. Since the to-be-removed part 3b is displaced in the circumferential direction with respect to the screw hole 3a, it is possible to suppress the stress caused by strongly pulling the operation part 3b-1 from acting on the screw hole 3a, for example, the screw hole 3a. Can be prevented.

このようにして、前記除去予定部３ｂが除去されたパッキン３は、座部３ｄの弦状部３ｃ及び円弧部３ｆが、座金４と壁２とが形成する間隙内からはみ出さないため、施工箇所は美観に優れることとなる。特に、弦状部３ｃは、座金４と壁２とが形成する隙間内に円弧部３ｆよりも深く入り込むことになるため、当該弦状部３ｃに発現する脆弱部３ｂ−２の破断部分が効果的に隠されて、施工箇所の美観向上により貢献される。   Thus, the packing 3 from which the planned removal portion 3b has been removed is constructed because the string-like portion 3c and the arc portion 3f of the seat portion 3d do not protrude from the gap formed by the washer 4 and the wall 2. The part will be excellent in aesthetics. Particularly, since the string-like part 3c enters deeper than the arc part 3f into the gap formed by the washer 4 and the wall 2, the broken part of the fragile part 3b-2 that appears in the string-like part 3c is effective. Concealed and contributed by improving the aesthetics of the construction site.

なお、上記実施形態を、次のように変更して具体化することも可能である。
・図３（ａ）〜図３（ｃ）に示すように、弦状部３ｃを削除するとともに、除去予定部３ｂを円弧部３ｆに連結すること。
・図４（ａ）〜図４（ｃ）に示すように、図３（ａ）〜図３（ｃ）の別例を変更し、座部３ｄの外周縁の一部を切り欠いて、この切欠き内で座部３ｄに除去予定部３ｂを連結してもよい。このようにすれば、除去予定部３ｂを、円弧部３ｆよりも内周側で座部３ｄに連結することができ、除去予定部３ｂを弦状部３ｃに連結することと同等の美観向上効果を得ることができる。
・除去予定部３ｂを、ネジ孔３ａに対して周方向へずらすことなく座部３ｄに連結すること。このようにすれば、操作部３ｂ−１とネジ孔３ａとが近くなるため、作業者は操作部３ｂ−１とネジ孔３ａとを同時に見易くなり、座金４のネジ孔４ａとの位置合わせをさらに容易に行い得る。 Note that the embodiment described above can be modified and embodied as follows.
As shown in FIG. 3A to FIG. 3C, the chordal portion 3c is deleted and the planned removal portion 3b is connected to the arc portion 3f.
As shown in FIGS. 4 (a) to 4 (c), another example of FIGS. 3 (a) to 3 (c) is changed to cut out a part of the outer peripheral edge of the seat 3d. You may connect the removal plan part 3b to the seat part 3d within a notch. If it does in this way, the removal plan part 3b can be connected with the seat part 3d in the inner peripheral side rather than the circular arc part 3f, and the aesthetics improvement effect equivalent to connecting the removal plan part 3b with the chord-like part 3c Can be obtained.
Connecting the planned removal portion 3b to the seat portion 3d without shifting in the circumferential direction with respect to the screw hole 3a. In this way, since the operation portion 3b-1 and the screw hole 3a are close to each other, the operator can easily see the operation portion 3b-1 and the screw hole 3a at the same time, and align the screw hole 4a of the washer 4 with each other. It can be done more easily.
