The root part 4 b of the shower head 4 is inserted from the end part 9 a far from the wall W of the shower holder part 9 and attached to the shower holder part 9. Thereby, the shower head 4 is hold | maintained so that it may extend diagonally upward from the wall W side. When the root portion 4 b of the shower head 4 is extracted obliquely upward from the shower holder portion 9, the hose 5 can be taken out of the shower holder portion 9 through the notch portion 9 b of the shower holder portion 9. Thereby, the shower head 4 can be routed without being restrained by the shower holder portion 9.

The long screw salvo 13 and the salvo 14 can be made of stainless steel, iron, brass or the like, but are preferably made of brass from the viewpoint of cost and corrosion resistance.

本体１２と長ねじザルボ１３とは、本体１２の先端部１２ａを長ねじザルボ１３の基端部１３ｂにねじ込むことで連結されている。長ねじザルボ１３とザルボ１４とは、長ねじザルボ１３の先端部１３ａをザルボ１４の基端部１４ｂにねじ込むことで連結されている。配管の端部Ｐとザルボ１４とは、ザルボ１４の先端部１４ａを配管の端部Ｐにねじ込むことで連結されている。この状態で、ザルボ１４の基端面１４ｃは、壁Ｗの外面Ｍ１に対して略面一となっている。また、本体１２の雄ねじｂ２と長ねじザルボ１３の雌ねじｂ３との隙間、長ねじザルボ１３の雄ねじｂ４とザルボ１４の雌ねじｂ５との隙間、及びザルボ１４の雄ねじｂ６と配管の端部Ｐの雌ねじｂ１との隙間は、それぞれシールテープ（不図示）等により密封されている。   The main body 12 and the long screw salvo 13 are connected by screwing the distal end portion 12 a of the main body 12 into the base end portion 13 b of the long screw salvo 13. The long screw salvo 13 and the salvo 14 are connected by screwing the distal end portion 13 a of the long screw salvo 13 into the proximal end portion 14 b of the salvo 14.

図３に示されるように、フランジ部材１１は円板状の部材であり、真鍮、ステンレス、亜鉛ダイキャスト、ガラス繊維で強化したポリフェニレンサルファイド樹脂、又はアルミニウム等により構成可能であるが、コストや加工性等の観点で、真鍮により構成されることが好ましい。また、耐食性や美観性等の観点で、フランジ部材１１の表面にはクロムメッキが施されることが好ましい。フランジ部材１１の中央には長ねじザルボ１３を挿通する挿通孔１１ａが形成されている。挿通孔１１ａの内周面には、長ねじザルボ１３の雄ねじｂ４に対応する雌ねじｂ７が形成されている。   As shown in FIG. 3, the flange member 11 is a disk-shaped member, and can be made of brass, stainless steel, zinc die cast, polyphenylene sulfide resin reinforced with glass fiber, aluminum, or the like. From the viewpoint of property and the like, it is preferable to be made of brass. Moreover, it is preferable that the surface of the flange member 11 is chrome-plated from the viewpoints of corrosion resistance, aesthetics, and the like. An insertion hole 11 a through which the long screw salvo 13 is inserted is formed in the center of the flange member 11. A female screw b7 corresponding to the male screw b4 of the long screw salvo 13 is formed on the inner peripheral surface of the insertion hole 11a.

水栓器具１の重量負荷を壁Ｗに分散させる観点から、フランジ部材１１の外径Ｄ２は、挿通孔１１ａの内径Ｄ１の２．５倍以上であることが好ましく、３．５倍以上であることがより好ましく、４．９倍以上であることが一層好ましい。具体的に、フランジ部材１１の外径Ｄ２は、３５ｍｍ以上であることが好ましく、５０ｍｍ以上であることがより好ましく、７０ｍｍ以上であることが一層好ましい。一方、フランジ部材１１自体の重量が過大になるのは好ましくないことから、フランジ部材１１の外径Ｄ２は１２０ｍｍ以下であることが好ましく、１１０ｍｍ以下であることがより好ましく、１００ｍｍ以下であることが一層好ましい。これらのことから、フランジ部材１１の外径Ｄ２は７０ｍｍ程度であることが特に好ましい。   From the viewpoint of dispersing the weight load of the faucet device 1 on the wall W, the outer diameter D2 of the flange member 11 is preferably 2.5 times or more, and more than 3.5 times the inner diameter D1 of the insertion hole 11a. It is more preferable that the ratio is 4.9 times or more. Specifically, the outer diameter D2 of the flange member 11 is preferably 35 mm or more, more preferably 50 mm or more, and even more preferably 70 mm or more. On the other hand, since it is not preferable that the weight of the flange member 11 itself is excessive, the outer diameter D2 of the flange member 11 is preferably 120 mm or less, more preferably 110 mm or less, and preferably 100 mm or less. Even more preferred. For these reasons, the outer diameter D2 of the flange member 11 is particularly preferably about 70 mm.

また、長ねじザルボ１３に対するフランジ部材１１の取り付け強度の観点から、フランジ部材１１の厚さは雌ねじｂ７のピッチの３倍以上であることが好ましい。例えば、フランジ部材１１の厚さは３ｍｍ以上であることが好ましく、４ｍｍ以上であることがより好ましく、５ｍｍ以上であることが一層好ましい。一方、フランジ部材１１自体の重量が過大になるのは好ましくない。また、フランジ部材１１の厚さが過大であると、壁Ｗからの水栓器具１の突出量を十分に小さくできないおそれがある。このため、フランジ部材１１の厚さは、１０ｍｍ以下であることが好ましく、９ｍｍ以下であることがより好ましく、８ｍｍ以下であることが一層好ましい。これらのことから、フランジ部材１１の厚さは５ｍｍ程度であることが特に好ましい。   Further, from the viewpoint of the attachment strength of the flange member 11 to the long screw salvo 13, the thickness of the flange member 11 is preferably three times or more the pitch of the female screw b7. For example, the thickness of the flange member 11 is preferably 3 mm or more, more preferably 4 mm or more, and even more preferably 5 mm or more. On the other hand, it is not preferable that the weight of the flange member 11 itself is excessive. Moreover, when the thickness of the flange member 11 is excessive, there is a possibility that the protruding amount of the faucet device 1 from the wall W cannot be made sufficiently small. For this reason, the thickness of the flange member 11 is preferably 10 mm or less, more preferably 9 mm or less, and even more preferably 8 mm or less. For these reasons, the thickness of the flange member 11 is particularly preferably about 5 mm.

フランジ部材１１の周囲には、ビスＢ挿通用の３個の開口１１ｂが形成されており、３個の開口１１ｂは、挿通孔１１ａと同心の円周Ｒ１に沿って並んでいる。水栓器具１の重量負荷を壁Ｗに分散させる観点から、円周Ｒ１の直径Ｄ３は、挿通孔１１ａの内径の２倍以上であることが好ましく、３倍以上であることがより好ましく、４倍以上であることが一層好ましい。具体的に、円周Ｒ１の外径は、５８ｍｍ以上であることが好ましく、７０ｍｍ以上であることがより好ましく、８４ｍｍ以上であることが一層好ましい。一方、開口１１ｂがフランジ部材１１の外周面１１ｃに近過ぎるとフランジ部材１１の強度が低下するため、フランジ部材１１の外径Ｄ２と円周Ｒ１の直径Ｄ３との差は、３ｍｍ以上であることが好ましく、７ｍｍ以上であることがより好ましく、１０ｍｍ以上であることが一層好ましい。これらのことから、円周Ｒ１の外径は５８ｍｍ程度であることが特に好ましい。   Three openings 11b for screw B insertion are formed around the flange member 11, and the three openings 11b are arranged along a circumference R1 concentric with the insertion hole 11a. From the viewpoint of dispersing the weight load of the faucet device 1 on the wall W, the diameter D3 of the circumference R1 is preferably at least twice the inner diameter of the insertion hole 11a, more preferably at least three times. It is still more preferable that it is twice or more. Specifically, the outer diameter of the circumference R1 is preferably 58 mm or more, more preferably 70 mm or more, and even more preferably 84 mm or more. On the other hand, if the opening 11b is too close to the outer peripheral surface 11c of the flange member 11, the strength of the flange member 11 is reduced. Therefore, the difference between the outer diameter D2 of the flange member 11 and the diameter D3 of the circumference R1 is 3 mm or more. Is preferable, more preferably 7 mm or more, and still more preferably 10 mm or more. For these reasons, the outer diameter of the circumference R1 is particularly preferably about 58 mm.

各開口１１ｂは、円周Ｒ１に沿って延びた長円形状を呈しており、各開口１１ｂの両端部は、各開口１１ｂの幅と同内径の半円状となっている。以下、挿通孔１１ａの中心Ｃ１から、各開口１１ｂの両端部の半円の中心Ｃ２，Ｃ２に向かって引いた２本の線分がなす角度θを、各開口１１ｂの開き角θという。各開口１１ｂの開き角θは、ビスＢと開口１１ｂとの位置の合わせ易さの観点で、４５°以上であることが好ましく、６０°以上であることがより好ましく、９０°以上であることが一層好ましい。一方、開口１１ｂ同士の間隔が小さ過ぎると、フランジ部材１１の強度が低下するため、各開口１１ｂの開き角θは、１５０°以下であることが好ましく、１２０°以下であることがより好ましい。これらのことから、各開口１１ｂの開き角θは、１００°程度であることが特に好ましい。   Each opening 11b has an oval shape extending along the circumference R1, and both end portions of each opening 11b have a semicircular shape having the same inner diameter as the width of each opening 11b. Hereinafter, an angle θ formed by two line segments drawn from the center C1 of the insertion hole 11a toward the centers C2 and C2 of the semicircles at both ends of each opening 11b is referred to as an opening angle θ of each opening 11b. The opening angle θ of each opening 11b is preferably 45 ° or more, more preferably 60 ° or more, and 90 ° or more from the viewpoint of easy alignment of the position of the screw B and the opening 11b. Is more preferable. On the other hand, if the distance between the openings 11b is too small, the strength of the flange member 11 is reduced. Therefore, the opening angle θ of each opening 11b is preferably 150 ° or less, and more preferably 120 ° or less. For these reasons, the opening angle θ of each opening 11b is particularly preferably about 100 °.

図２に示されるように、フランジ部材１１は、挿通孔１１ａの雌ねじｂ７と長ねじザルボ１３の雄ねじｂ４とが噛み合うように、長ねじザルボ１３の外周に取り付けられている。すなわち、挿通孔１１ａの周辺部分が、長ねじザルボ１３の外周に取り付けられる取付部Ｆ１となっている。また、フランジ部材１１は、ザルボ１４の基端側に位置し、ザルボ１４の基端面１４ｃ及び壁Ｗの外面Ｍ１に当接している。この状態で、各開口１１ｂにビスＢが挿通され、各ビスＢが壁Ｗにねじ込まれている。各ビスＢを締め付けることで、フランジ部材１１が壁Ｗに固定されている。即ち、各開口１１ｂの周辺部分が、壁Ｗに固定される固定部Ｆ２となっている。なお、ビスＢのねじ込み箇所は、１か所であっても２か所であってもよいが、水栓器具１の重量を確実に壁Ｗに分散させる観点から、３か所以上であることが好ましい。いずれかの開口１１ｂに２個以上のビスＢを挿通し、４か所以上にビスＢをねじ込んでもよい。   As shown in FIG. 2, the flange member 11 is attached to the outer periphery of the long screw salvo 13 so that the female screw b7 of the insertion hole 11a and the male screw b4 of the long screw salvo 13 are engaged with each other. That is, the peripheral portion of the insertion hole 11 a is an attachment portion F <b> 1 that is attached to the outer periphery of the long screw salvo 13. Further, the flange member 11 is located on the proximal end side of the salvo 14 and is in contact with the proximal end face 14 c of the salvo 14 and the outer surface M <b> 1 of the wall W. In this state, screws B are inserted into the openings 11b, and the screws B are screwed into the walls W. The flange member 11 is fixed to the wall W by tightening each screw B. That is, the peripheral portion of each opening 11b is a fixing portion F2 fixed to the wall W. The screw B may be screwed in at one place or two places, but from the viewpoint of reliably distributing the weight of the faucet device 1 to the wall W, it should be at least three places. Is preferred. Two or more screws B may be inserted into any of the openings 11b, and the screws B may be screwed into four or more locations.

カバー部材１５，１６は、薄板素材をプレスすることで形成され、椀形状を呈している。薄板素材の厚さは、フランジ部材１１の厚さよりも小さい。カバー部材１５，１６は、ステンレス、樹脂、真鍮などにより構成可能であるが、強度及びコストの両立の観点で、真鍮により構成されることが好ましい。また、耐食性等の観点で、カバー部材１５，１６の表面にはクロムメッキが施されることが好ましい。   The cover members 15 and 16 are formed by pressing a thin plate material and have a bowl shape. The thickness of the thin plate material is smaller than the thickness of the flange member 11. The cover members 15 and 16 can be made of stainless steel, resin, brass or the like, but are preferably made of brass from the viewpoint of achieving both strength and cost. Further, from the viewpoint of corrosion resistance and the like, it is preferable that the surfaces of the cover members 15 and 16 are subjected to chrome plating.

第１のカバー部材１５の底部１５ａには、本体１２の先端部１２ａを挿通する挿通孔１５ｂが形成されている。挿通孔１５ｂの周辺部分は、本体１２の雄ねじｂ２の谷部に嵌り込むように成形されている。すなわち、挿通孔１５ｂの周辺部分は、略一山分のねじ山を構成している。   An insertion hole 15 b through which the distal end portion 12 a of the main body 12 is inserted is formed in the bottom portion 15 a of the first cover member 15. A peripheral portion of the insertion hole 15b is formed so as to be fitted into a valley portion of the male screw b2 of the main body 12. That is, the peripheral portion of the insertion hole 15b constitutes a screw thread for approximately one thread.

第２のカバー部材１６の底部１６ａには、内側に窪んだ窪み部１６ｂが形成されており、窪み部１６ｂの中央に、本体１２の先端部１２ａを挿通する挿通孔１６ｃが形成されている。挿通孔１６ｃの周辺部分は、第１のカバー部材１５の挿通孔１５ｂの周辺部分と同様に、略一山分のねじ山を構成している。第２のカバー部材１６の外径は、第１のカバー部材１５の外径よりも小さく、本体１２の軸心Ｌ３上から見て、ビスＢより内側に収まる大きさとなっている。   The bottom portion 16a of the second cover member 16 is formed with a recessed portion 16b recessed inward, and an insertion hole 16c through which the distal end portion 12a of the main body 12 is inserted is formed at the center of the recessed portion 16b. The peripheral portion of the insertion hole 16c constitutes a thread for substantially one thread, similarly to the peripheral portion of the insertion hole 15b of the first cover member 15. The outer diameter of the second cover member 16 is smaller than the outer diameter of the first cover member 15 and fits inside the screw B when viewed from the axis L3 of the main body 12.

カバー部材１５，１６は、それぞれ壁Ｗに向かって開口するように配置され、挿通孔１５ｂ，１６ｃの周辺部分と本体１２の雄ねじｂ２とが噛み合うように、本体１２の先端部１２ａの外周に取り付けられている。第１のカバー部材１５は、第２のカバー部材１６より壁Ｗ側に配置されている。本体１２の軸心Ｌ３を中心にカバー部材１５，１６を回転させ、水栓部２側に移動させると、第２のカバー部材１６が本体１２の凸部１２ｂに当接する。第２のカバー部材１６の底部１６ａには窪み部１６ｂが形成されていることから、雄ねじｂ２と凸部１２ｂとの間の不完全ねじ部が窪み部１６ｂ内に収容される。これにより、挿通孔１６ｃの周辺部分が不完全ねじ部に達することが防止される。   The cover members 15 and 16 are disposed so as to open toward the wall W, and are attached to the outer periphery of the distal end portion 12a of the main body 12 so that the peripheral portions of the insertion holes 15b and 16c and the male screw b2 of the main body 12 are engaged with each other. It has been. The first cover member 15 is disposed closer to the wall W than the second cover member 16. When the cover members 15 and 16 are rotated around the axis L3 of the main body 12 and moved to the faucet portion 2 side, the second cover member 16 contacts the convex portion 12b of the main body 12. Since the recessed part 16b is formed in the bottom part 16a of the 2nd cover member 16, the incomplete thread part between the external thread b2 and the convex part 12b is accommodated in the recessed part 16b. This prevents the peripheral portion of the insertion hole 16c from reaching the incomplete screw portion.

第１のカバー部材１５は、フランジ部材１１を覆って壁Ｗの外面Ｍ１に当接している。これにより、フランジ部材１１及びビスＢが保護されると共に、美観性が向上する。また、第１のカバー部材１５は本体１２の外周に取り付けられていることから、長ねじザルボ１３も第１のカバー部材１５に覆われている。これにより、長ねじザルボ１３も保護されると共に、美観性が更に向上する。第１のカバー部材１５は椀形状を呈しているので、壁Ｗの外面Ｍ１には第１のカバー部材１５の口縁部１５ｃのみが当接する。更に、薄板素材からなる第１のカバー部材１５は撓み易い。このため、壁Ｗ側に向かうように第１のカバー部材１５を締め付けるのみで、壁Ｗと第１のカバー部材１５との隙間を十分に小さくすることができる。更に、第１のカバー部材１５の撓みの反力により雌ねじｂ３と雄ねじｂ２との摩擦力を保ち、長ねじザルボ１３と本体１２との緩みを抑制することができる。   The first cover member 15 covers the flange member 11 and is in contact with the outer surface M1 of the wall W. Thereby, the flange member 11 and the screw B are protected, and the aesthetics are improved. Further, since the first cover member 15 is attached to the outer periphery of the main body 12, the long screw salvo 13 is also covered with the first cover member 15. Thereby, the long screw salvo 13 is also protected and the aesthetics are further improved. Since the first cover member 15 has a bowl shape, only the edge 15c of the first cover member 15 abuts on the outer surface M1 of the wall W. Furthermore, the first cover member 15 made of a thin plate material is easily bent. For this reason, the clearance gap between the wall W and the 1st cover member 15 can be made small enough only by tightening the 1st cover member 15 toward the wall W side. Furthermore, the frictional force between the female screw b3 and the male screw b2 can be maintained by the reaction force of the bending of the first cover member 15, and loosening between the long screw salvo 13 and the main body 12 can be suppressed.

第２のカバー部材１６は、第１のカバー部材１５の外側にはみ出した本体１２の雄ねじｂ２を覆い、第１のカバー部材１５の底部１５ａに当接している。これにより、本体１２の雄ねじｂ２が保護されると共に、美観性が更に向上する。第２のカバー部材１６は椀形状を呈していることから、第１のカバー部材１５の底部１５ａには、第２のカバー部材１６の口縁部１６ｄのみが当接する。更に、薄板素材からなるカバー部材１５，１６は撓み易い。このため、第１のカバー部材１５側に向かうように第２のカバー部材１６を締め付けるのみで、第１のカバー部材１５と第２のカバー部材１６との隙間を十分に小さくすることができる。また、第１のカバー部材１５の撓みの反力に、第２のカバー部材１６の撓みの反力を加え、雌ねじｂ３と雄ねじｂ２との摩擦力を高め、長ねじザルボ１３と本体１２との緩みを更に抑制することができる。   The second cover member 16 covers the male screw b <b> 2 of the main body 12 that protrudes outside the first cover member 15, and is in contact with the bottom portion 15 a of the first cover member 15. Thereby, the external thread b2 of the main body 12 is protected and the aesthetics are further improved. Since the second cover member 16 has a bowl shape, only the mouth edge 16 d of the second cover member 16 abuts on the bottom 15 a of the first cover member 15. Furthermore, the cover members 15 and 16 made of a thin plate material are easily bent. For this reason, the clearance gap between the 1st cover member 15 and the 2nd cover member 16 can fully be made small only by tightening the 2nd cover member 16 so that it may go to the 1st cover member 15 side. Further, the bending reaction force of the second cover member 16 is added to the bending reaction force of the first cover member 15 to increase the frictional force between the female screw b3 and the male screw b2, so that the long screw salvo 13 and the main body 12 Looseness can be further suppressed.

続いて、水栓器具１の取付方法について説明する。まず、図４に示されるように、壁Ｗの誘導孔Ｈ１の周囲の３か所にビス固定用の下孔Ｈ２を形成する。壁Ｗが石膏等のもろい素材からなる場合には、下孔Ｈ２を補強する市販のアンカー部材１７を埋め込んでもよい。また、ザルボ１４を配管の端部Ｐにねじ込む（図２参照）。   Then, the attachment method of the faucet device 1 is demonstrated. First, as shown in FIG. 4, screw fixing pilot holes H2 are formed at three locations around the guide hole H1 of the wall W. When the wall W is made of a brittle material such as plaster, a commercially available anchor member 17 that reinforces the pilot hole H2 may be embedded. Further, the salvo 14 is screwed into the end portion P of the pipe (see FIG. 2).

次に、図４及び図５に示されるように、フランジ部材１１の挿通孔１１ａに長ねじザルボ１３の先端部１３ａをねじ込み、長ねじザルボ１３の外周にフランジ部材１１を取り付ける。次に、図５及び図６に示されるように、長ねじザルボ１３の先端部１３ａをザルボ１４の基端部１４ｂにねじ込む。その後、長ねじザルボ１３の軸心Ｌ３を中心にフランジ部材１１を回転させることで、フランジ部材１１を壁Ｗ側に移動させる。フランジ部材１１が壁Ｗの外面Ｍ１に当接すると、更にフランジ部材１１を締め付ける。これにより、長ねじザルボ１３の雄ねじｂ４とフランジ部材１１の雌ねじｂ７とが締まり合い、フランジ部材１１と長ねじザルボ１３とのがたつきが抑制される。次に、図７及び図８に示されるように、フランジ部材１１の開口１１ｂを通し、ビスＢを下孔Ｈ２にねじ込み、各ビスＢを締め付けて、フランジ部材１１を壁Ｗに固定する。   Next, as shown in FIGS. 4 and 5, the distal end portion 13 a of the long screw salvo 13 is screwed into the insertion hole 11 a of the flange member 11, and the flange member 11 is attached to the outer periphery of the long screw salvo 13. Next, as shown in FIGS. 5 and 6, the distal end portion 13 a of the long screw salvo 13 is screwed into the proximal end portion 14 b of the salvo 14. Then, the flange member 11 is moved to the wall W side by rotating the flange member 11 around the axis L3 of the long screw salvo 13. When the flange member 11 contacts the outer surface M1 of the wall W, the flange member 11 is further tightened. Thereby, the male screw b4 of the long screw salvo 13 and the female screw b7 of the flange member 11 are fastened together, and rattling between the flange member 11 and the long screw salvo 13 is suppressed. Next, as shown in FIGS. 7 and 8, the screws B are screwed into the pilot holes H <b> 2 through the openings 11 b of the flange member 11, and the screws B are tightened to fix the flange member 11 to the wall W.

次に、図８及び図９に示されるように、第２のカバー部材１６の外面側から、挿通孔１６ｃに本体１２の先端部１２ａをねじ込むことで、先端部１２ａの外周に第２のカバー部材１６を取り付ける。このとき、本体１２の凸部１２ｂにより、第２のカバー部材１６の移動が規制されるため、挿通孔１６ｃの周辺部分が雄ねじｂ２の不完全ねじ部に達することが防止される。また、第１のカバー部材１５の外面側から、挿通孔１５ｂに本体１２の先端部１２ａをねじ込むことで、先端部１２ａの外周に第１のカバー部材１５を取り付ける。   Next, as shown in FIGS. 8 and 9, the second cover member 16 is screwed into the insertion hole 16 c from the outer surface side of the second cover member 16, so that the second cover is formed on the outer periphery of the distal end portion 12 a. The member 16 is attached. At this time, since the movement of the second cover member 16 is restricted by the convex portion 12b of the main body 12, the peripheral portion of the insertion hole 16c is prevented from reaching the incomplete screw portion of the male screw b2. Further, the first cover member 15 is attached to the outer periphery of the distal end portion 12a by screwing the distal end portion 12a of the main body 12 into the insertion hole 15b from the outer surface side of the first cover member 15.

次に、図９及び図１０に示されるように、本体１２の先端部１２ａを長ねじザルボ１３の基端部１３ｂにねじ込み、締め付ける。その後、本体１２の軸心Ｌ３を中心に第１のカバー部材１５を回転させることで、第１のカバー部材１５を壁Ｗ側に移動させ、壁Ｗに当接させて締め付ける。すると、第１のカバー部材１５が撓み、壁Ｗと第１のカバー部材１５との隙間が十分に小さくなる。これにより、長ねじザルボ１３及びフランジ部材１１が第１のカバー部材１５にしっかりと覆われる。また、第１のカバー部材１５の撓みの反力により、雌ねじｂ３と雄ねじｂ２との摩擦力が保たれ、長ねじザルボ１３と本体１２との緩みが抑制される。   Next, as shown in FIGS. 9 and 10, the distal end portion 12 a of the main body 12 is screwed into the proximal end portion 13 b of the long screw salvo 13 and tightened. Thereafter, the first cover member 15 is rotated about the axis L3 of the main body 12, whereby the first cover member 15 is moved to the wall W side and is brought into contact with the wall W and tightened. Then, the 1st cover member 15 bends and the clearance gap between the wall W and the 1st cover member 15 becomes small enough. As a result, the long screw salvo 13 and the flange member 11 are firmly covered by the first cover member 15. Further, the frictional force between the female screw b3 and the male screw b2 is maintained by the reaction force of the bending of the first cover member 15, and loosening between the long screw salvo 13 and the main body 12 is suppressed.

その後、本体１２の軸心Ｌ３を中心に第２のカバー部材１６を回転させることで、第２のカバー部材１６を第１のカバー部材１５側に移動させ、第１のカバー部材１５に当接させて締め付ける。これにより、第２のカバー部材１６及び第１のカバー部材１５が撓み、第１のカバー部材１５と第２のカバー部材１６との隙間が十分に小さくなる。これにより、第１のカバー部材１５の挿通孔１５ｂから外側にはみ出した雄ねじ部ｂ２が第２のカバー部材１６にしっかりと覆われる。また、第１のカバー部材１５の撓みの反力に、第２のカバー部材１６の撓みの反力が加わることで、雌ねじｂ３と雄ねじｂ２との摩擦力が高まり、長ねじザルボ１３と本体１２との緩みが更に抑制される。   Thereafter, by rotating the second cover member 16 about the axis L3 of the main body 12, the second cover member 16 is moved to the first cover member 15 side and comes into contact with the first cover member 15. And tighten. Thereby, the 2nd cover member 16 and the 1st cover member 15 bend, and the crevice between the 1st cover member 15 and the 2nd cover member 16 becomes small enough. As a result, the male screw part b <b> 2 protruding outward from the insertion hole 15 b of the first cover member 15 is firmly covered by the second cover member 16. Further, by adding the reaction force of the second cover member 16 to the reaction force of the bending of the first cover member 15, the frictional force between the female screw b3 and the male screw b2 is increased, and the long screw salvo 13 and the main body 12 are increased. Is further suppressed.

なお、水栓器具１は、長ねじザルボ１３及び第１のカバー部材１５を用いずに取り付けることも可能である。すなわち、水栓器具１の取付構造は、長ねじザルボ１３及び第１のカバー部材１５を有さなくてもよい。この場合、第１のカバー部材１５の代わりにフランジ部材１１を本体１２に取り付け、本体１２の先端部１２ａをザルボ１４の基端部１４ｂにねじ込む。次に、フランジ部材１１を回転させることで壁Ｗ側に移動させ、壁Ｗの外面Ｍ１に当接させて締め付ける。その状態でフランジ部材１１を壁Ｗにビスで固定する。そして、第２のカバー部材１６を回転させることでフランジ部材１１側に移動させ、フランジ部材１１に当接させて締め付ける。第２のカバー部材１６は椀形状を呈していることから、フランジ部材１１には、第２のカバー部材１６の口縁部１６ｄのみが当接する。更に、薄板素材からなる第２のカバー部材１６は撓み易い。このため、第２のカバー部材１６をフランジ部材１１に当接させて締め付けるのみで、第２のカバー部材１６の口縁部１６ｄをフランジ部材１１にしっかりと当接させ、本体１２に対するフランジ部材１１の傾動を抑制することができる。   The faucet device 1 can be attached without using the long screw salvo 13 and the first cover member 15. That is, the attachment structure of the faucet device 1 may not have the long screw salvo 13 and the first cover member 15. In this case, the flange member 11 is attached to the main body 12 instead of the first cover member 15, and the distal end portion 12 a of the main body 12 is screwed into the proximal end portion 14 b of the salvo 14. Next, the flange member 11 is rotated and moved to the wall W side, and is brought into contact with the outer surface M1 of the wall W and tightened. In this state, the flange member 11 is fixed to the wall W with screws. Then, the second cover member 16 is rotated to move to the flange member 11 side, and is brought into contact with the flange member 11 and tightened. Since the second cover member 16 has a bowl shape, only the edge portion 16 d of the second cover member 16 contacts the flange member 11. Furthermore, the second cover member 16 made of a thin plate material is easily bent. For this reason, just by abutting and tightening the second cover member 16 against the flange member 11, the edge 16 d of the second cover member 16 is firmly abutted against the flange member 11, and the flange member 11 with respect to the main body 12 is secured. Can be suppressed.

以上により、水栓器具１の取り付けが完了する。このように、水栓器具１の取付構造Ａ１では、フランジ部材１１を筒状体１０（長ねじザルボ１３）の軸心Ｌ３に沿って移動させ、筒状体１０に対するフランジ部材１１の取り付け位置を調整することができる。これにより、筒状体１０（ザルボ１４）の先端部１４ａを配管の端部Ｐにねじ込んだ状態で、フランジ部材１１を壁Ｗの外面Ｍ１に確実に当接させ、壁Ｗに固定することができる。筒状体１０の外周に取り付けられたフランジ部材１１を壁Ｗに固定することで、配管の端部Ｐにねじ込まれた筒状体１０（ザルボ１４）の先端部１４ａを強く締め付けることなく水栓器具１を固定することができる。従って、水栓器具１を取り付ける際に、配管の端部Ｐにかかる負荷を軽減することができる。   Thus, the attachment of the faucet device 1 is completed. As described above, in the attachment structure A1 of the faucet device 1, the flange member 11 is moved along the axis L3 of the tubular body 10 (long screw salvo 13), and the attachment position of the flange member 11 with respect to the tubular body 10 is changed. Can be adjusted. Thus, the flange member 11 can be reliably brought into contact with the outer surface M1 of the wall W and fixed to the wall W in a state where the distal end portion 14a of the cylindrical body 10 (salvo 14) is screwed into the end portion P of the pipe. it can. By fixing the flange member 11 attached to the outer periphery of the tubular body 10 to the wall W, the faucet without strongly tightening the distal end portion 14a of the tubular body 10 (salvo 14) screwed into the end portion P of the pipe The instrument 1 can be fixed. Therefore, when attaching the faucet instrument 1, the load concerning the edge part P of piping can be reduced.

なお、水栓器具１には浄水機能付きのシャワーヘッド４が付属しており、その分取付構造Ａ１にかかる負荷が大きい。更に、シャワーヘッド４がシャワーホルダー部９に対して着脱自在であることから、取付構造Ａ１にはシャワーヘッド４の着脱に伴う負荷もかかる。このため、筒状体１０の外周に取り付けられたフランジ部材１１を壁Ｗに固定することで、配管の端部Ｐにかかる負荷をより顕著に軽減することができる。   In addition, the faucet device 1 is provided with a shower head 4 having a water purification function, and the load applied to the mounting structure A1 is large accordingly. Furthermore, since the shower head 4 is detachable with respect to the shower holder portion 9, a load accompanying attachment / detachment of the shower head 4 is also applied to the attachment structure A1. For this reason, by fixing the flange member 11 attached to the outer periphery of the cylindrical body 10 to the wall W, the load applied to the end portion P of the pipe can be remarkably reduced.

筒状体１０（長ねじザルボ１３）の外周面には雄ねじｂ４が形成され、フランジ部材１１には、筒状体１０（長ねじザルボ１３）が挿通される挿通孔１１ａが形成され、挿通孔１１ａの内周面に雄ねじｂ４に対応する雌ねじｂ７が形成されている。このため、筒状体１０の軸心Ｌ３を中心にフランジ部材１１を回転させることで、筒状体１０に対するフランジ部材１１の取り付け位置を無段階に調整することができる。また、筒状体１０の先端部１４ａを配管の端部Ｐにねじ込んだ状態で、壁Ｗ側に向かうようにフランジ部材１１を締め付けると、筒状体１０の雄ねじｂ４とフランジ部材１１の雌ねじｂ７とが締まり合う。これにより、筒状体１０とフランジ部材１１とのがたつきを抑制し、水栓器具１をよりしっかりと固定することができる。   A male screw b4 is formed on the outer peripheral surface of the cylindrical body 10 (long screw salvo 13), and an insertion hole 11a through which the cylindrical body 10 (long screw salvo 13) is inserted is formed in the flange member 11. A female screw b7 corresponding to the male screw b4 is formed on the inner peripheral surface of 11a. For this reason, the attachment position of the flange member 11 with respect to the cylindrical body 10 can be adjusted steplessly by rotating the flange member 11 centering on the axial center L3 of the cylindrical body 10. FIG. Further, when the flange member 11 is tightened toward the wall W side with the distal end portion 14a of the cylindrical body 10 screwed into the pipe end P, the male screw b4 of the cylindrical body 10 and the female screw b7 of the flange member 11 are tightened. And tighten. Thereby, rattling between the tubular body 10 and the flange member 11 can be suppressed, and the faucet device 1 can be more firmly fixed.

フランジ部材１１には、壁Ｗへの固定用のビスＢが挿通される開口１１ｂが形成され、開口１１ｂは、筒状体１０が挿通される挿通孔１１ａを囲む円周Ｒ１に沿って延びている。このため、フランジ部材１１の回転により、壁Ｗに設けられたビスＢ用の下孔Ｈ２と、開口１１ｂとの位置合わせを容易に行うことができる。   The flange member 11 is formed with an opening 11b through which the fixing screw B to the wall W is inserted. The opening 11b extends along a circumference R1 surrounding the insertion hole 11a through which the cylindrical body 10 is inserted. Yes. For this reason, the rotation of the flange member 11 allows easy alignment of the pilot hole H2 for the screw B provided in the wall W and the opening 11b.

筒状体１０は、壁Ｗに向かって延在する筒状の本体１２と、本体１２の先端部１２ａに着脱自在に連結され、壁Ｗに向かって延在する筒状の長ねじザルボ１３と、を有し、フランジ部材１１は長ねじザルボ１３の外周に取り付けられている。このため、長ねじザルボ１３の長さの設定によって、壁Ｗからの水栓器具１の突出量を容易に調整することができる。また、長ねじザルボ１３をしっかりと固定した後に、長ねじザルボ１３に対して本体１２を取り付けることができ、水栓器具１の取り付けが更に容易になる。   The cylindrical body 10 includes a cylindrical main body 12 extending toward the wall W, a cylindrical long screw salvo 13 that is detachably connected to the distal end portion 12a of the main body 12, and extends toward the wall W. The flange member 11 is attached to the outer periphery of the long screw salvo 13. For this reason, the protrusion amount of the faucet device 1 from the wall W can be easily adjusted by setting the length of the long screw salvo 13. Moreover, after fixing the long screw salvo 13 firmly, the main body 12 can be attached with respect to the long screw salvo 13, and attachment of the faucet device 1 becomes still easier.

なお、ザルボ１４と本体１２との間に長ねじザルボ１３が介在すると、本体１２が壁Ｗから遠ざかるので、水栓器具１の取り付け後に取付構造Ａ１にかかるモーメントが大きくなる。このため、筒状体１０の外周に取り付けられたフランジ部材１１を壁Ｗに固定することで、配管の端部Ｐにかかる負荷をより顕著に軽減することができる。   In addition, when the long screw salvo 13 is interposed between the salvo 14 and the main body 12, the main body 12 moves away from the wall W, so that a moment applied to the mounting structure A1 after the faucet device 1 is attached increases. For this reason, by fixing the flange member 11 attached to the outer periphery of the cylindrical body 10 to the wall W, the load applied to the end portion P of the pipe can be remarkably reduced.

筒状体１０は、フランジ部材１１の取り付け位置より先端側に着脱自在に設けられた筒状のザルボ１４を有し、ザルボ１４が配管の端部Ｐにねじ込まれる。このため、配管の端部Ｐにねじ込まれたザルボ１４を取り外すことなく、水栓器具１の交換を行うことができる。これにより、水栓器具１の交換の度に配管の端部Ｐにかかる負荷をより軽減することができる。   The cylindrical body 10 has a cylindrical salvo 14 that is detachably provided on the distal end side from the attachment position of the flange member 11, and the salvo 14 is screwed into the end portion P of the pipe. For this reason, the faucet device 1 can be replaced without removing the salvo 14 screwed into the end P of the pipe. Thereby, the load concerning the edge part P of piping can be further reduced whenever the faucet device 1 is replaced.

フランジ部材１１は、壁Ｗの外面Ｍ１に当接すると共にザルボ１４の基端面１４ｃに当接する。ザルボ１４とフランジ部材１１との当接により、フランジ部材１１をよりしっかりと固定することができる。   The flange member 11 abuts on the outer surface M <b> 1 of the wall W and abuts on the proximal end surface 14 c of the salvo 14. The flange member 11 can be more firmly fixed by the contact between the salvo 14 and the flange member 11.

（参考形態）
図１１に示されるように、水栓器具の参考形態の取付構造Ａ２は、上述した長ねじザルボ１３及び第１のカバー部材１５を用いずに水栓器具１を取り付ける形態において、フランジ部材１８を固定するビスＢの頭部が第２のカバー部材１６で覆われるように構成されたものである。 ( Reference form)
As shown in FIG. 11, the attachment structure A2 of the reference form of the faucet device is a form in which the faucet device 1 is attached without using the long screw salvo 13 and the first cover member 15 described above. The head of the screw B to be fixed is configured to be covered with the second cover member 16.

取付構造Ａ２のフランジ部材１８は、開口１８ｂが開口１１ｂと異なっていることを除き、フランジ部材１１と同様に構成されている。フランジ部材１８の中央には、挿通孔１１ａと同様の挿通孔１８ａが形成されており、挿通孔１８ａの内周面には雌ねじｂ７と同様の雌ねじｂ８が形成されている。挿通孔１８ａの周囲には、ビスＢ挿通用の３個の開口１８ｂが形成されている。フランジ部材１８のカバー部材１６側の面には、挿通孔１８ａと同心の円周に沿って凹部１８ｃが形成されており、各開口１８ｂは、凹部１８ｃの底部に形成されている（図１２参照）。凹部１８ｃ及び３個の開口１８ｂは、カバー部材１６の口縁部１６ｄより内側に配置されている。   The flange member 18 of the mounting structure A2 is configured in the same manner as the flange member 11 except that the opening 18b is different from the opening 11b. An insertion hole 18a similar to the insertion hole 11a is formed in the center of the flange member 18, and an internal thread b8 similar to the internal thread b7 is formed on the inner peripheral surface of the insertion hole 18a. Three openings 18b for inserting screws B are formed around the insertion hole 18a. A recess 18c is formed on the surface of the flange member 18 on the cover member 16 side along a circumference concentric with the insertion hole 18a, and each opening 18b is formed at the bottom of the recess 18c (see FIG. 12). ). The recess 18 c and the three openings 18 b are disposed on the inner side of the mouth edge 16 d of the cover member 16.

フランジ部材１８は、雌ねじｂ８と雄ねじｂ２とが噛み合うように、本体１２の先端部１２ａの外周に取り付けられ、ザルボ１４の基端面１４ｃ及び壁Ｗの外面Ｍ１に当接している。この状態で、各開口１８ｂにはビスＢが挿通され、各ビスＢが壁Ｗにねじ込まれている。フランジ部材１８は、各ビスＢを締め付けることで壁Ｗに固定されている。各ビスＢの頭部は、凹部１８ｃに入り込み、凹部１８ｃの底面に接している。   The flange member 18 is attached to the outer periphery of the distal end portion 12a of the main body 12 so that the female screw b8 and the male screw b2 mesh with each other, and is in contact with the base end surface 14c of the salvo 14 and the outer surface M1 of the wall W. In this state, screws B are inserted into the openings 18b, and the screws B are screwed into the walls W. The flange member 18 is fixed to the wall W by tightening each screw B. The head of each screw B enters the recess 18c and is in contact with the bottom surface of the recess 18c.

カバー部材１６の口縁部１６ｄは、凹部１８ｃの周辺部分に当接している。各開口１８ｂが口縁部１６ｄより内側に配置されていることから、ビスＢの頭部はカバー部材１６により覆われている。また、各ビスＢの頭部が凹部１８ｃに入り込んでいることから、各ビスＢの頭部とカバー部材１６との干渉が確実に防止されている。   The edge portion 16d of the cover member 16 is in contact with the peripheral portion of the recess 18c. Since each opening 18b is disposed inside the mouth edge 16d, the head of the screw B is covered with the cover member 16. Further, since the head of each screw B enters the recess 18c, interference between the head of each screw B and the cover member 16 is reliably prevented.

このような取付構造Ａ２では、ビスＢの頭部をカバー部材１６で覆う前に、ビスＢを固定する必要がある。そこで、カバー部材１６が取り付けられた本体１２の先端部１２ａをザルボ１４の基端部１４ｂにねじ込む前に、フランジ部材１８を壁Ｗに固定する必要がある。以下、取付構造Ａ２を備えた水栓器具の取付方法について説明する。   In such an attachment structure A2, it is necessary to fix the screw B before the head of the screw B is covered with the cover member 16. Therefore, the flange member 18 needs to be fixed to the wall W before the distal end portion 12a of the main body 12 to which the cover member 16 is attached is screwed into the proximal end portion 14b of the salvo 14. Hereinafter, the attachment method of the faucet appliance provided with attachment structure A2 is demonstrated.

まず、図１２に示されるように、取付構造Ａ１の場合と同様に、壁Ｗの誘導孔Ｈ１の周囲の３か所にビスＢ固定用の下孔Ｈ３を形成する。また、ザルボ１４を配管の端部Ｐにねじ込む（図１１参照）。次に、図１２及び図１３に示されるように、ザルボ１４の基端部１４ｂの内周面と、挿通孔１８ａの内周面とが揃うように、フランジ部材１８を壁Ｗの外面Ｍ１に当接させる。この状態で、図１３及び図１４に示されるように、開口１８ｂを通してビスＢを下孔Ｈ３にねじ込み、締め付けて、フランジ部材１８を壁Ｗに固定する。   First, as shown in FIG. 12, as in the case of the mounting structure A1, the pilot holes H3 for fixing the screws B are formed at three locations around the guide hole H1 of the wall W. Further, the salvo 14 is screwed into the end portion P of the pipe (see FIG. 11). Next, as shown in FIGS. 12 and 13, the flange member 18 is placed on the outer surface M1 of the wall W so that the inner peripheral surface of the base end portion 14b of the salvo 14 and the inner peripheral surface of the insertion hole 18a are aligned. Make contact. In this state, as shown in FIGS. 13 and 14, the screw B is screwed into the pilot hole H3 through the opening 18b and tightened to fix the flange member 18 to the wall W.

次に、図１４及び図１５に示されるように、カバー部材１６の外面側から、挿通孔１６ｃに本体１２の先端部１２ａをねじ込むことで、先端部１２ａの外周にカバー部材１６を取り付ける。そして、図１５に示されるように、先端部１２ａをフランジ部材１８の挿通孔１８ａ及びザルボ１４の基端部１４ｂにねじ込む。カバー部材１６の口縁部１６ｄがフランジ部材１８に当接すると、先端部１２ａを更に締め付ける。これにより、カバー部材１６の口縁部１６ｄをフランジ部材１８にしっかりと当接させ、本体１２に対するフランジ部材１８の傾動を抑制することができる。また、カバー部材１６の撓みの反力により、フランジ部材１８の雌ねじｂ８と本体１２の雄ねじｂ２とが締まり合い、フランジ部材１８と本体１２とのがたつきが抑制される。また、雌ねじｂ８と雄ねじｂ２との摩擦力が保たれ、フランジ部材１８と本体１２との緩みが抑制される。   Next, as shown in FIGS. 14 and 15, the cover member 16 is attached to the outer periphery of the distal end portion 12 a by screwing the distal end portion 12 a of the main body 12 into the insertion hole 16 c from the outer surface side of the cover member 16. Then, as shown in FIG. 15, the distal end portion 12 a is screwed into the insertion hole 18 a of the flange member 18 and the proximal end portion 14 b of the salvo 14. When the edge portion 16d of the cover member 16 contacts the flange member 18, the distal end portion 12a is further tightened. Thereby, the edge part 16d of the cover member 16 can be firmly brought into contact with the flange member 18, and the tilting of the flange member 18 with respect to the main body 12 can be suppressed. Further, due to the reaction force of the bending of the cover member 16, the female screw b <b> 8 of the flange member 18 and the male screw b <b> 2 of the main body 12 are tightened, and rattling between the flange member 18 and the main body 12 is suppressed. Further, the frictional force between the female screw b8 and the male screw b2 is maintained, and the looseness between the flange member 18 and the main body 12 is suppressed.

以上により、取付構造Ａ２を備えた水栓器具の取り付けが完了する。取付構造Ａ２によれば、フランジ部材１８を覆う第１のカバー部材１５を有しない形態であっても、ビスＢの頭部を第２のカバー部材１６により保護することができる。   Thus, the attachment of the faucet device provided with the attachment structure A2 is completed. According to the attachment structure A2, even if the first cover member 15 that covers the flange member 18 is not provided, the head of the screw B can be protected by the second cover member 16.

以上、本発明の好適な実施形態について説明してきたが、本発明は必ずしも上述した実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で様々な変更が可能である。例えば、カバー部材１５，１６を用いなくてもよい。 The preferred embodiments of the present invention have been described above, but the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, it is not necessary to use the cover member 15, 16.
