【発明の属する技術分野】
本発明は、建築物内に設けられたユニットバスの外側から内側に給水、給湯するためにユニットバス壁に設けられる通水管の貫通部を形成するための貫通部形成装置に関するものである。
【０００２】
【従来の技術】
従来より、建築物内にはユニットバスが設けられ、そのユニットバスを構成するユニットバス壁には、浴槽に給水、給湯するための通水管を貫通させるための貫通部が形成されている（例えば、特許文献１参照。）。図１０に示すように、前記貫通部１００を形成するために、ユニットバス壁Ｕには孔部Ｓが穿設されている。また、ユニットバス壁Ｕの内側には、内側部材としての円盤状をなす合成樹脂製の継手プレート１０１が配設され、ユニットバス壁Ｕの外側には四角板状をなす合成樹脂製の取付部材１０２及び水栓ボックス１０３が配設されている。図９及び図１０に示すように、前記継手プレート１０１の縁部には、継手プレート１０１の周方向に沿って、ビス１０４を挿通可能なビス挿通孔１０１ａが４箇所に形成されている。図１０に示すように、前記水栓ボックス１０３は前記取付部材１０２とほぼ同形状をなす鍔板１０３ａを備え、その鍔板１０３ａの周縁部には、前記ビス１０４が螺合可能なナット（図示せず）が埋設されている。
【０００３】
そして、図９に示すように、前記取付部材１０２をユニットバス壁Ｕに固定し、図１０に示すように、その取付部材１０２に水栓ボックス１０３を取付ける。その後、継手プレート１０１とユニットバス壁Ｕとの間で、ゴム材料製のパッキン１０５を挟んだ状態で、継手プレート１０１のビス挿通孔１０１ａから複数のビス１０３を水栓ボックス１０３のナットに螺合する。すると、継手プレート１０１と水栓ボックス１０３とが互いに引寄せられ、取付部材１０２を介した継手プレート１０１及び水栓ボックス１０３によりユニットバス壁Ｕが挟持される。また、継手プレート１０１とユニットバス壁Ｕとの間にパッキン１０５が挟持され、そのパッキン１０５に継手プレート１０１が圧接する。その結果、ユニットバス壁Ｕに継手プレート１０１及び水栓ボックス１０３が取付けられ、貫通部１００が形成される。

【０００５】
【発明が解決しようとする課題】
ところが、上記従来技術において、継手プレート１０１をユニットバス壁Ｕに取付けるために複数本のビス１０４が使用されている。そのため、継手プレート１０１においては、ビス１０４により、ビス挿通孔１０１ａの周縁部がユニットバス壁Ｕ側に向かって強力に押圧され、水栓ボックス１０３においてはナットの周縁部がユニットバス壁Ｕ側へ強力に引寄せられる。即ち、継手プレート１０１のビス挿通孔１０１ａの周縁部と、水栓ボックス１０３のナットの周縁部とにより、ユニットバス壁Ｕが強く挟持されるが、その他の部位はユニットバス壁Ｕの挟持が弱くなるという問題があった。また、複数のビス１０４を使用するため、各ビス１０４のナットに対する螺合量に差が生じると、継手プレート１０１及び水栓ボックス１０３によりユニットバス壁Ｕを強く挟持する箇所と、弱く挟持する箇所が発生してしまう虞があるという問題があった。
【０００６】
加えて、継手プレート１０１、取付部材１０２及び水栓ボックス１０３には、ビス１０４を挿通するための孔が形成されているため、ユニットバス壁Ｕの内側と外側とがそれら孔により連通する状態となっている。その結果、前記孔内を水が流通し、ユニットバス壁Ｕの内側から外側に水が漏れる虞があるという問題があった。
【０００７】
本発明は、上記従来技術に存在する問題点に着目してなされたものである。その目的とするところは、貫通孔の周縁部を均等な力で挟持して貫通部を形成することができるとともに、ユニットバス壁の内外への流体の流通を防止することができるユニットバス壁の通水管の貫通部形成装置を提供することにある。
【０００８】

【００２２】
【発明の実施の形態】
（第１の実施形態）
以下、本発明を具体化したユニットバス壁の通水管の貫通部形成装置の一実施形態を図１〜図５にしたがって説明する。
【００２３】
まず、ユニットバスについて説明する。図３に示すように、建築物内に構築されたコンクリート面には、多数のジャッキ１２を介して防水パン１３が水平に支持固定されている。前記防水パン１３の上面には浴槽１４が設置され、さらに防水パン１３の周囲にユニットバス壁１５が立設されている。また、前記ユニットバス壁１５には、前記浴槽１４に給水、給湯するための通水管を貫通した状態に設置するための貫通部Ｋが形成されている。
【００２４】
次に、図１に示すように、前記ユニットバス壁１５に設けられる貫通部Ｋを形成するための貫通部形成装置２０について説明する。前記貫通部形成装置２０は、前記ユニットバス壁１５の内側（図１では左側）に配設される内側部材２１と、当該内側部材２１から延設された延設手段としての延設部２６と、ユニットバス壁１５の外側（図１では右側）に配設される外側部材２２と、前記延設部２６に螺着される螺合部材２３とより主に構成されている。
【００２５】
まず、前記内側部材２１について説明する。図２に示すように、合成樹脂製の内側部材２１は円盤状をなす止水部２５と、その止水部２５に立設された円筒状をなす筒状部２４とより形成されている。止水部２５は前記筒状部２４の外径よりも大径に形成されている。
【００２６】
前記筒状部２４の外周面には第１ねじ部２４ａが螺刻されている。また、筒状部２４の外面において、前記第１ねじ部２４ａよりも、内側部材２１の中央側には係止リブ２４ｃが４箇所に突設され、各係止リブ２４ｃはそれぞれ筒状部２４の軸線方向に延びるように形成されている。図１に示すように、筒状部２４内には、内側部材２１内に挿入された通水管１６が挿通される挿通路２４ｂが形成されている。また、筒状部２４はその軸線が止水部２５に対して斜めに交差するように形成されている。
【００２７】
前記内側部材２１において、筒状部２４の外周には合成樹脂製の化粧プレート２７が装着される。この化粧プレート２７は円環状をなす化粧カバー２７ａとその化粧カバー２７ａから円筒状に延設された化粧筒部２７ｂとから構成されている。前記化粧カバー２７ａは、化粧プレート２７が筒状部２４に装着された状態で、前記止水部２５を被覆可能な大きさに形成されている。また、前記化粧筒部２７ｂは、化粧カバー２７ａに対して軸線が斜めに傾斜して延びるように形成されているとともに、先端面が斜めに傾斜するように形成されている。図２に示すように、化粧筒部２７ｂの内周面には係止凹部２７ｃが４箇所に凹設され、化粧プレート２７が内側部材２１に装着された状態で、係止凹部２７ｃと前記係止リブ２４ｃとが係止し、化粧プレート２７が周方向へ回転することが防止される。
【００２８】
筒状部２４の先端には、合成樹脂製の取付ナット２８を用いて合成樹脂製の引出部材２９が取付け可能に形成されている。図１に示すように、前記取付ナット２８は略円筒状をなし、その先端の内周縁には嵌合溝２８ａが凹設されている。また、取付ナット２８の内周面には、前記第１ねじ部２４ａに螺合可能な内周ねじ部２８ｂが螺刻されている。図２に示すように、前記引出部材２９は円盤状をなす基板部２９ａを備え、その基板部２９ａの周縁部には枠状部２９ｂが、基板部２９ａの両面側に向けて突出形成されている。この枠状部２９ｂのうち、基板部２９ａの上側に延びる部位は、前記嵌合溝２８ａに嵌合可能に形成されている。また、基板部２９ａの上面には略円筒状をなす一対の引出口２９ｃが引出部として突設され、その引出部材２９の内側から前記各引出口２９ｃの外側へ通水管１６を引出可能に形成されている。
【００２９】
そして、嵌合溝２８ａに枠状部２９ｂを嵌合させて取付ナット２８と引出部材２９とを組付け、その取付ナット２８を筒状部２４の先端に螺着することにより、内側部材２１には引出口２９ｃが設けられる。このとき、嵌合溝２８ａの内周面と枠状部２９ｂの周面とが圧接するため、取付ナット２８と引出部材２９との組付け部位を止水することが可能となっている。
【００３０】
前記内側部材２１には、前記延設部２６が一体形成されている。即ち、図２に示すように、止水部２５からは逆Ｕ字状をなし、止水部２５から離れる方向へ延びる延設部２６が形成されている。この延設部２６の基端側の内部には案内路２６ｂが形成され、この案内路２６ｂは延設部２６内に下側から挿通された通水管１６を、ユニットバス壁１５の内側に引き出されるように案内するために形成されている。延設部２６の下部は、同延設部２６の長さ方向に沿って延びるように切り欠き部２６ｄが開口形成され、その切り欠き部２６ｄを形成する相対向する縁部には、延設部２６の長さ方向に延びる係合面２６ａが形成されている。この延設部２６は、その軸線が前記止水部２５に対して直交するように形成されている。また、延設部２６の先端の外面には、同延設部２６の円弧に沿って第２ねじ部２６ｃが螺刻されている。
【００３１】
次に、前記外側部材２２について説明する。合成樹脂製の外側部材２２は、円弧状に湾曲して延びるガイド手段としてのガイド部３１を備え、そのガイド部３１の上部には略円筒状をなす連結筒部３０が形成されている。前記連結筒部３０は略円筒状をなす外周筒部３２により外郭が形成され、その外周筒部３２の一端部（図２では左端部）には第１鍔部３２ａが形成されているとともに、他端部（図２では右端部）には第２鍔部３２ｂが形成されている。また、連結筒部３０において、前記外周筒部３２の内側には内周筒部３３が形成され、その内周筒部３３は外周筒部３２の内周下部に一体形成されている。また、内周筒部３３の外周面と外周筒部３２の内周面との間には、外側部材２２の正面視において、下方に開口する円弧状をなす挿入孔３４が形成され、その挿入孔３４内に前記延設部２６が挿入可能に形成されている。また、前記内周筒部３３の他端面には、略Ｕ字状に延びる延長部３３ｂが形成されている。さらに、内周筒部３３の両側の下部外側面及び前記延長部３３ｂの両側には係合部３３ａが形成されている。
【００３２】
そして、図４に示すように、挿入孔３４に延設部２６が挿入された状態では、延設部２６の先端は連結筒部３０の他端面より外方へ突出し、第２ねじ部２６ｃが露出するようになっている。また、前記延長部３３ｂは、一対の係合面２６ａの間に配設され、延長部３３ｂと延設部２６とが係合可能な位置に配設されるようになっている。
【００３３】
図１及び図２に示すように、前記ガイド部３１は円筒状をなすとともに、前記内周筒部３３の内側から斜め下方へ湾曲しながら延びるように形成されている。このガイド部３１は上端側が連結筒部３０の一端側に開口し、下端側が下方に開口するようになっている。そして、そのガイド部３１により、同ガイド部３１の下端側から挿通された通水管１６を、連結筒部３０内、さらに延設部２６内へ案内するようになっている。
【００３４】
また、ガイド部３１の下端部には、合成樹脂製の鞘管３５を連結するための連結部３６が接続されている。図１に示すように、この連結部３６の上端の内周縁には係合突条３７が内方へ向かって突設され、その係合突条３７をガイド部３１の先端の外周面に形成された係合凹条３１ｂに係合することにより連結部３６がガイド部３１に接続されている。連結部３６の下端内周縁には、連結部３６内へ延びる係止爪３８が複数箇所に形成されている。そして、連結部３６内に鞘管３５が挿入され、前記係止爪３８が鞘管３５の外周面に係止されることにより、鞘管３５が連結部３６を介してガイド部３１に連結される。
【００３５】
前記螺合部材２３は、合成樹脂材料により円筒状に形成され、その内周面に前記第２ねじ部２６ｃに螺合可能なねじ山２３ａが螺刻されている。ユニットバス壁１５の内面と、止水部２５との間には、シール部材としてのパッキンＰが配設される。このパッキンＰはゴム材料により円環状に形成されている。
【００３６】
さて、上記貫通部形成装置２０を使用して、ユニットバス壁１５に貫通部Ｋを形成するには、まず、ユニットバス壁１５の内側に配設された内側部材２１において、パッキンＰを延設部２６に外挿する。図４及び図５に示すように、挿入孔３４が貫通孔１５ａに合致するように外側部材２２をユニットバス壁１５の外側に配設し、パッキンＰが外挿された延設部２６をユニットバス壁１５の内側から貫通孔１５ａ内、さらに挿入孔３４内に挿入し、第２ねじ部２６ｃを外側部材２２の外部に露出させる。延設部２６が挿入孔３４に挿入された状態では、筒状部２４が斜め上方へ延びるようになっている。そして、ユニットバス壁１５の外側から螺合部材２３をねじ山２３ａに螺合して、同螺合部材２３を延設部２６に螺着する。このとき、螺合部材２３の回転により延設部２６を介して内側部材２１が回転しようとするが、係合面２６ａが係合部３３ａに係合するため、その回転が規制される。そのため、筒状部２４が斜め上方に配設されたままの状態で、延設部２６に螺合部材２３が螺着される。
【００３７】
螺合部材２３が第２ねじ部２６ｃに螺進されるに伴い、螺合部材２３の端面が第２鍔部３２ｂに当接し、外側部材２２がユニットバス壁１５側へ押される。また、内側部材２１と螺合部材２３とが互いに引寄せられ、内側部材２１がユニットバス壁１５側へ引寄せられる。このとき、螺合部材２３が回転することにより内側部材２１をユニットバス壁１５側へ引寄せるため、内側部材２１全体がユニットバス壁１５側へ引寄せられる。また、止水部２５を局部的にユニットバス壁１５側へ引寄せるのではなく、延設部２６を介して止水部２５全体をユニットバス壁１５側へ引寄せている。そのため、止水部２５の全周がパッキンＰをユニットバス壁１５側へ押圧した状態で、同パッキンＰの端面全周が、貫通孔１５ａの周縁部となるユニットバス壁１５の内面に圧接している。
【００３８】
そして、止水部２５と螺合部材２３との間に、外側部材２２及びパッキンＰを介してユニットバス壁１５が挟持され、ユニットバス壁１５に内側部材２１及び外側部材２２が取付けられる。即ち、止水部２５と螺合部材２３とにより、ユニットバス壁１５を均等な力で挟持して、同ユニットバス壁１５に貫通部Ｋが形成される。その後、ユニットバス壁１５の内面と止水部２５との間のパッキンＰの外周にコーキング処理を行い、さらに、筒状部２４の外周に化粧プレート２７を装着する。なお、コーキング作業は必ず行う必要はなく、省略してもよい。
【００３９】
続いて、化粧プレート２７において、係止凹部２７ｃと係止リブ２４ｃとを係止させ、その化粧プレート２７をユニットバス壁１５側に移動させる。すると、化粧カバー２７ａにより止水部２５が被覆されるとともに、化粧筒部２７ｂにより、第１ねじ部２４ａより止水部２５側の筒状部２４が被覆される。その結果、前記コーキングが化粧カバー２７ａにより被覆され、コーキングが露出することにより外観が低下するといった不具合の防止やコーキングを劣化しにくくすることができる。
【００４０】
次に、外側部材２２において、連結部３６に鞘管３５を連結し、その鞘管３５内に一対の通水管１６を挿通する。そして、それら通水管１６はガイド部３１の内周面により斜め上方へ案内され、延設部２６内の案内路２６ｂにより筒状部２４内の挿通路２４ｂへ案内される。さらに、挿通路２４ｂにより通水管１６は、延設部２６の軸線に対して斜め上方へ延びるように案内されて筒状部２４内から内側部材２１の外へ送り出される。
【００４１】
このとき、一対の通水管１６は、ガイド部３１により湾曲させられた状態で送り込み作業が行われるため、通水管１６が湾曲状態から直線状に戻ろうとする力によりガイド部３１、延設部２６及び筒状部２４は内側から上方へ押し上げられる。しかし、内側部材２１は、螺合部材２３によりその全体がユニットバス壁１５側へ引寄せられているため、通水管１６の押圧により内側部材２１がユニットバス壁１５から離間することが防止される。
【００４２】
次いで、嵌合溝２８ａに枠状部２９ｂを嵌合させて取付ナット２８と引出部材２９とを組付ける。そして、引出部材２９が取付けられた取付ナット２８の内側に一対の通水管１６を挿入し、さらに、通水管１６を引出口２９ｃ内に挿通した後、引出部材２９内からその外側へ引き出す。このとき、引出口２９ｃの内周面が通水管１６の外周面に圧接するため、引出口２９ｃの内周面と通水管１６の外周面との間に止水構造が形成される。そして、取付ナット２８のみを回転させて内周ねじ部２８ｂを第１ねじ部２４ａに螺合すると、引出部材２９が筒状部２４側へ押圧された状態で筒状部２４に螺着される。この引出部材２９の螺着状態では、引出部材２９のみを周方向に回転させることができ、一対の引出口２９ｃの位置を上下左右に調節することができる。
【００４３】
そして、図１に示すように、取付ナット２８が筒状部２４に螺着されると、引出部材２９が内側部材２１に取着され、内側部材２１の上端部に引出口２９ｃが斜め上方へ延びるように配設される。そのため、各引出口２９ｃから引き出された通水管１６は、内側部材２１の内側から斜め上方へ延びるように配設される。その結果、内側部材２１、外側部材２２、延設部２６及び螺合部材２３によりユニットバス壁１５に貫通部Ｋが形成され、通水管１６がユニットバス壁１５の外側から同ユニットバス壁１５を貫通して配設される。さらに、前記通水管１６がそれぞれ浴槽１４まで配設され、湯水を供給するための水栓器具（図示せず）に接続される。
【００４４】
貫通部Ｋがユニットバス壁１５に形成された状態において、例えばユニットバス壁１５の内側で水が使用され、貫通部Ｋが水を被ったとき、嵌合溝２８ａの内周面と枠状部２９ｂの上端縁の外周面との間、引出口２９ｃの内周面と通水管１６の外周面との間から水が内側部材２１内に侵入することが防止される。また、ユニットバス壁１５の内面と、内側部材２１の止水部２５の端面には、パッキンＰが密接し、止水部２５とユニットバス壁１５との間はコーキングされている。そのため、止水部２５とユニットバス壁１５との間から内側部材２１内に水が侵入することが防止され、貫通孔１５ａからユニットバス壁１５の外側に水が漏れ出ることが防止される。
【００４５】
上記実施形態によれば、以下のような効果を得ることができる。
（１）ユニットバス壁１５の内側に内側部材２１を配設し、その内側部材２１から延びる延設部２６を、ユニットバス壁１５を貫通させてユニットバス壁１５の外側へ延設し、さらに延設部２６に螺合部材２３を螺着した。そのため、延設部２６に対する螺合部材２３の螺合により、内側部材２１全体をユニットバス壁１５側へ引寄せ、止水部２５の全体を均等な力でパッキンＰに圧接させることができる。即ち、パッキンＰを介した止水部２５と、外側部材２２を介した螺合部材２３とにより、ユニットバス壁１５の内側及び外側から同ユニットバス壁１５を均等な力で挟持して貫通部Ｋを形成することができる。その結果、パッキンＰとユニットバス壁１５との圧接面において、その圧接の度合いに差が生じることなく、圧接の弱い箇所から水がユニットバス壁１５の外側へ漏れ出る虞を無くすことができる。また、上述のように漏水を防止することができるため、止水部２５とユニットバス壁１５との間のコーキング作業を不可欠なものとせず、貫通部Ｋを形成する作業の簡易化を図ることができる。

（２）ユニットバス壁１５を貫通して内側部材２１の延設部２６に螺合部材２３を螺合することにより、貫通部Ｋがユニットバス壁１５に形成される。即ち、貫通部Ｋには貫通孔１５ａ以外に、ユニットバス壁１５を貫通する孔が形成されず、貫通部Ｋを形成する部材にもビスを挿通するための孔が形成されていない。従って、貫通部Ｋを形成するための部材にビスを挿通するための孔が形成されていた従来と異なり、ユニットバス壁１５の内側と外側とが貫通孔１５ａ以外の孔により連通することがない。その結果、貫通孔１５ａ以外の孔内を水が流通し、ユニットバス壁１５の内外に水が流通する虞を無くすことができる。
【００４７】
（３）貫通孔１５ａを貫通した延設部２６に螺合部材２３を螺合することにより、貫通部Ｋがユニットバス壁１５に形成される。そのため、パッキンＰを介した止水部２５及び第１鍔部３２ａが、貫通孔１５ａの周縁部に圧接するだけの面積を有していれば、貫通部Ｋを形成することができる。また、貫通孔１５ａにはビスを貫通させる必要がないため、従来の貫通部を形成するときに穿設された貫通孔よりも、本実施形態の貫通孔１５ａを小径とすることができる。従って、従来の貫通部を形成する部材において、貫通孔１５ａの周縁に配設される部位が、ビスを挿通可能とし、そのビスの締め付け力に耐えることのできる強度を有する大きさを必要とする場合と異なり、本実施形態では内側部材２１及び外側部材２２を小型化することができる。また、ビスを使用しないため、そのビスが錆びることが無くなり、貫通部Ｋに錆びが発生する虞を無くすことができる。
【００４８】
（４）ユニットバス壁１５の外側に延設された延設部２６に対し、ユニットバス壁１５の外側から螺合部材２３を螺着して貫通部Ｋが形成される。そのため、貫通部Ｋの形成作業においては、内側部材２１を回転させる必要がなく、内側部材２１の回転による筒状部２４の向きを考慮する必要が無くなり、貫通部Ｋの形成作業を行うことができる。
【００４９】
（５）延設部２６内には案内路２６ｂが形成され、その案内路２６ｂは挿通路２４ｂと連通している。そのため、ガイド部３１により延設部２６内まで案内された通水管１６を、案内路２６ｂにより内側部材２１内に案内することができ、通水管１６を内側部材２１内に挿通して貫通部Ｋを形成する作業を容易に行うことができる。
【００５０】
（６）内側部材２１には延設部２６が一体形成されているため、筒状部２４と延設部２６とが別体形成されている場合と比較して、貫通部Ｋの形成作業を容易に行うことができる。また、筒状部２４と延設部２６とが別体形成されている場合のように、筒状部２４と延設部２６との接続部位における漏水防止を考慮する必要が無くなるため、貫通部Ｋの構成を簡易化することができる。
【００５１】
（７）内側部材２１とは別体形成された外側部材２２に延設部２６を挿入し、外側部材２２から突出した延設部２６に螺合部材２３を螺合することができる。従って、外側部材２２は延設部２６に沿って移動可能に形成され、延設部２６への螺合部材２３の螺進により、外側部材２２をユニットバス壁１５側へ移動させることができるとともに、第２ねじ部２６ｃへの螺合部材２３の螺進距離を長くすることができる。そのため、螺合部材２３により内側部材２１をユニットバス壁１５に強固に固定することができるとともに、螺合部材２３を延設部２６に確実に螺着することができる。
【００５２】
（８）ガイド部３１を備えた外側部材２２を、内側部材２１とは別体形成し、外側部材２２内に延設部２６を挿入した。そのため、延設部２６に螺合部材２３を螺合することにより、外側部材２２をユニットバス壁１５に近接させることができる。即ち、ガイド部３１をユニットバス壁１５の壁面に沿うように配設することができ、通水管１６をガイド部３１内から貫通孔１５ａ及び挿通路２４ｂに挿入するとき、通水管１６をその軸線方向に沿った曲げ量を少なくすることができ、その挿入作業を行いやすくすることができる。
【００５３】
（９）内側部材２１と螺合部材２３との間に外側部材２２が介在して貫通部Ｋが形成されている。そのため、外側部材２２がワッシャ的な機能を発揮して、螺合部材２３を緩みにくくすることができる。従って、パッキンＰに対して止水部２５が圧接した状態を維持することができる。
【００５４】
（１０）係合面２６ａと係合部３３ａとの係合により、螺合部材２３の延設部２６に対する螺進に伴い内側部材２１が回転するのを防止することができる。そのため、内側部材２１を、筒状部２４が斜め上方へ延びるように配設した後は、螺合部材２３の螺合作業時に、筒状部２４が回転しないように内側部材２１を手で保持する必要がなく、貫通部Ｋの形成作業を容易に行うことができる。特に、筒状部２４がユニットバス壁１５の内面から斜め上方に延びるように維持した状態で螺合部材２３を延設部２６に螺合することができる。従って、貫通部Ｋの形成作業は、後の通水管１６の引出方向を考慮しながら容易に行うことができる。
【００５５】
（１１）ユニットバス壁１５の外側にはガイド部３１が設けられ、そのガイド部３１は、ユニットバス壁１５の壁面に対して斜めに延びるように延設部２６内にまで延び、案内路２６ｂに連通している。そのため、ガイド部３１により通水管１６を延設部２６内にまで速やかに案内することができ、その後の内側部材２１内への挿通作業を容易に行うことができる。
【００５６】
（１２）ガイド部３１には連結部３６が形成されているため、その連結部３６により鞘管３５をガイド部３１に容易に連結することができる。
（第２の実施形態）
次に、本発明を具体化した通水管の貫通部形成装置の第２の実施形態を図６にしたがって説明する。なお、第２の実施形態は、第１の実施形態の内側部材及び外側部材を変更したのみの構成であるため、同様の部分についてはその詳細な説明を省略する。
【００５７】
図６に示すように、第２の実施形態の貫通部形成装置４０は、前記ユニットバス壁１５の内側（左側）に配設される内側部材４１と、同内側部材４１に設けられた延接手段を形成する延設部材４６と、前記ユニットバス壁１５の外側（右側）で前記延設部材４６に螺着される螺合部材４３と、より主に構成されている。
【００５８】
まず、前記内側部材４１について説明する。合成樹脂製の内側部材４１は、円盤状をなす止水部４５と、その止水部４５から立設された略円筒状をなす筒状部４４とより形成されている。前記止水部４５の裏面には、その周方向に延びる嵌着溝４５ｂが形成され、嵌着溝４５ｂにはパッキンＰが、シール部材として嵌着されている。また、止水部４５の裏面において、前記筒状部４４の周縁部となる位置には取付突条４５ａが内側へ突出するように形成されている。前記筒状部４４の外周面には第１ねじ部４４ａが螺刻されている。また、筒状部４４は、その軸線が止水部４５に対して斜め上方に傾斜するように形成されているとともに、筒状部４４内に挿通路４４ｂが形成されている。
【００５９】
なお、筒状部４４の先端には、合成樹脂製の取付ナット５０を用いて合成樹脂製の引出部材５１が取付け可能に形成されている。前記取付ナット５０は第１の実施形態の取付ナット２８とほぼ同形状に形成され、嵌合溝５０ａ及び内周ねじ部５０ｂが形成されている。また、引出部材５１は第１の実施形態の引出部材２９とほぼ同形状に形成され、基板部５１ａ、枠状部５１ｂ及び引出口５１ｃを備えている。そして、取付ナット５０を用いて引出部材５１を筒状部４４に取付けることにより、引出口５１ｃにより内側部材４１に引出部が設けられている。
【００６０】
次に、前記延設部材４６について説明する。前記延設部材４６は合成樹脂材料によりエルボ状に形成されている。前記延設部材４６は、円弧状に延びるガイド部４８と、そのガイド部４８の上端に円筒状に形成された本体部４７とより形成されている。前記本体部４７の一端縁（図６では左端縁）には、本体部４７の周方向に沿って外方へ延びる取付リブ４７ａが形成され、本体部４７の外周面にはねじ部４７ｂが螺刻されている。また、本体部４７内には、ガイド部４８から挿入された通水管１６を内側部材４１内に案内するための案内路４６ｂが形成されている。この案内路４６ｂは本体部４７の軸線方向に対し、斜めに延びるように形成されている。前記ガイド部４８は、本体部４７から斜めに延びるように湾曲形成されている。ガイド部４８の先端には前記鞘管３５を連結可能とすべく第１の実施形態の連結部３６と同様の構成の連結部４９が形成されている。合成樹脂製の前記螺合部材４３は、円筒状をなし、内周面には前記ねじ部４７ｂに螺合可能なねじ山４３ａが螺刻されている。
【００６１】
さて、上記貫通部形成装置４０を使用して貫通部Ｋを形成するには、まず、取付突条４５ａと取付リブ４７ａとを係合させて筒状部４４と延設部材４６とを一体に組付ける。すると、内側部材４１と延設部材４６とが一体化されて、延設部材４６により、内側部材４１に延設手段が延設される。そして、ユニットバス壁１５の内側からガイド部４８を貫通孔１５ａ内に挿入し、ガイド部４８をユニットバス壁１５の外側へ配設する。次に、ガイド部４８の先端側から、同ガイド部４８に螺合部材４３を外挿する。続いて、連結部４９に鞘管３５を連結する。
【００６２】
続いて、前記延設部材４６に形成されたねじ部４７ｂにねじ山４３ａを螺合して螺合部材４３を延設部材４６に螺着する。螺合部材４３がねじ部４７ｂに螺進されるに伴い、延設部材４６及び内側部材４１がユニットバス壁１５側へ引寄せられる。そして、止水部４５の嵌着溝４５ｂの内周面全体が各パッキンＰに圧接し、さらに、一対のパッキンＰの全体がユニットバス壁１５の内面に圧接される。また、螺合部材４３の端面全周がユニットバス壁１５の外面に圧接される。その結果、内側部材４１、延設部材４６及び螺合部材４３によりユニットバス壁１５に貫通部Ｋが形成される。そして、ガイド部４８から案内路４６ｂ内に挿入された通水管１６が、案内路４６ｂにより内側部材４１の挿通路４４ｂ内に案内されるとともに、ユニットバス壁１５を貫通して引出口５１ｃからユニットバス壁１５の内側へ送り出される。
【００６３】
第２の実施形態によれば、第１の実施形態の（１）〜（３）、（１１）及び（１２）と同様の効果に加えて以下の効果を得ることができる。
（１）延設部材４６内には案内路４６ｂが形成されている。そして、延設部材４６が内側部材４１に組付けられたとき、案内路４６ｂが挿通路４４ｂと連通する。そのため、案内路４６ｂにより通水管１６を内側部材４１内へ案内することができ、通水管１６をユニットバス壁１５の外側から内側へ挿通する作業を容易に行うことができる。
【００６４】
（２）貫通孔１５ａの内側では、案内路４６ｂは斜め上方へ延びる状態で挿通路４４ｂに連通するように形成されている。従って、案内路４６ｂが、ユニットバス壁１５の壁面に対して直交して延びるように形成されている場合と異なり、通水管１６が、ガイド部４８から案内路４６ｂに挿通されたとき、通水管１６を挿通路４４ｂに案内することができる。従って、通水管１６を貫通部Ｋ内を挿通させる作業を行いやすくすることができる。
【００６５】
（３）延設部材４６にガイド部４８を一体形成したため、内側部材４１に延設手段を設けると同時に、ガイド部４８を貫通部Ｋに設けることができる。そのため、ガイド部４８と案内路４６ｂとが確実に連通し、ガイド部４８に挿通された通水管１６を延設部材４６内に確実に挿通することができる。
【００６６】
（４）内側部材４１と延設部材４６とを別体形成したため、両部材が一体形成されている場合と比較して、各部材の成形金型の構造を簡易なものとすることができる。また、
（第３の実施形態）
次に、本発明を具体化した通水管の貫通部形成装置の第３の実施形態を図７及び図８にしたがって説明する。なお、第３の実施形態は、第１の実施形態の内側部材の延設部及び外側部材を変更したのみの構成であるため、同様の部分についてはその詳細な説明を省略する。
【００６７】
図８に示すように、第３の実施形態の貫通部形成装置６０は、内側部材６１と、同内側部材６１に設けられた延接手段としての延設部６２と、前記延設部６２に螺着される螺合部材６３と、外側部材６４とより主に構成されている。
【００６８】
まず、前記内側部材６１について説明する。図７に示すように、合成樹脂製の内側部材６１は、第１の実施形態の筒状部２４と同様の構成の筒状部６５を備えるとともに、その筒状部６５の基端側の周縁部に形成された円盤状をなす止水部６６を備えている。前記筒状部６５の外周面には第１ねじ部６５ａが螺刻され、筒状部６５内に挿通路６５ｂが形成されている。なお、筒状部６５の先端には、第１の実施形態の取付ナット２８と同様の構成の取付ナット６７を用いて、第１の実施形態の引出部材２９と同様の構成の引出部材６８が取付け可能に形成されている。即ち、取付ナット６７は嵌合溝６７ａ及び内周ねじ部６７ｂを備え、引出部材６８は基板部６８ａ、枠状部６８ｂ及び引出口６８ｃを備えている。
【００６９】
次に、前記延設部６２について説明する。前記延設部６２は止水部６６から円筒状に延びるように形成され、延設部６２の外面には、切り欠き部としての係合凹条６２ａが延設部６２の軸線に沿って延びるように凹設されている。また、図８に示すように、延設部６２の内側には案内路６２ｂが形成され、延設部６２の外周面において、前記係合凹条６２ａを除いた位置には、第２ねじ部６２ｃが螺刻されている。加えて、延設部６２の内周面には、ねじ山６２ｄが螺刻されている。
【００７０】
前記延設部６２には、前記ユニットバス壁１５の外側から同延設部６２内に通水管１６を案内するガイド手段としてのガイド部材６９が設けられている。このガイド部材６９はパイプ状をなし、円弧状に湾曲して延びるように形成されている。ガイド部材６９の一端部（上端部）には、前記ねじ山６２ｄと螺合可能なねじ部６９ａが螺刻され、他端部（下端部）には、第１の実施形態の連結部３６と同様の構成の連結部７０が設けられている。そして、その連結部７０により、ガイド部材６９の下端に合成樹脂製の鞘管３５を連結することができる。
【００７１】
前記螺合部材６３は第１の実施形態の螺合部材２３と同様の構成を有するように形成されている。図７に示すように、前記外側部材６４は円環状に形成され、その内側が挿入孔として形成されている。また、外側部材６４の内周面の相対向する位置には、係合突部６４ａが係合部として突接されている。そして、延設部６２が外側部材６４内に挿入されると、前記係合突部６４ａが係合凹条６２ａ内に係合するようになっている。
【００７２】
さて、第３の実施形態の貫通部形成装置６０を使用してユニットバス壁１５に貫通部Ｋを形成するには、まず、ユニットバス壁１５の内側に配設された内側部材６１において、パッキンＰを延設部６２に外挿する。次に、延設部６２を貫通孔１５ａ内に挿入してユニットバス壁１５を貫通させた後、その延設部６２の係合凹条６２ａに係合突部６４ａを係合させた状態で、同延設部６２に外側部材６４を取付ける。このとき、内側部材６１は筒状部６５は斜め上方を向くように配設されている。
【００７３】
続いて、螺合部材６３が外挿されたガイド部材６９のねじ部６９ａを、延設部６２のねじ山６２ｄに螺合して内側部材６１とガイド部材６９とを組付ける。続けて、ガイド部材６９に外挿された螺合部材６３を第２ねじ部６２ｃに螺合する。すると、係合突部６４ａと係合凹条６２ａとの係合により、延設部６２及び内側部材６１が回転することなく、螺合部材６３が延設部６２に螺着される。その結果、図８に示すように、筒状部６５が斜め上方に配設されたままの状態で、内側部材６１及び螺合部材６３がユニットバス壁１５側へ引寄せられる。そして、止水部６６の端面全体がパッキンＰに圧接し、さらに、そのパッキンＰの全体がユニットバス壁１５の内面に圧接される。また、螺合部材６３の端面全周が外側部材６４の端面に圧接し、その外側部材６４がユニットバス壁１５の外面に圧接される。すると、パッキンＰを介した止水部６６と、外側部材６４を介した螺合部材６３とにより、ユニットバス壁１５の内外両側から均等な力でユニットバス壁１５を挟持して貫通部Ｋがユニットバス壁１５に形成される。
【００７４】
その結果、内側部材６１、延設部６２及び螺合部材６３によりユニットバス壁１５に貫通部Ｋが形成され、通水管１６がユニットバス壁１５を貫通して配設される。また、延設部６２からガイド部材６９が斜め下方へ湾曲しながら延びるように配設される。そして、ガイド部材６９内及び案内路６２ｂ内に通水管１６を挿通し、さらにガイド部材６９及び案内路６２ｂによりそれら通水管１６を挿通路６５ｂ内へ案内させる。そして、挿通路６５ｂ内に挿通された通水管１６は、引出部材６８からユニットバス壁１５の外側へ送り出され、その引出部材６８は取付ナット６７により筒状部６５に取付けられる。なお、延設部６２からガイド部材６９を螺退してもよく、このとき、延設部６２の内側に形成される案内路６２ｂはその軸方向への長さが長くなる。
【００７５】
従って、第３の実施形態によれば、第１の実施形態の（１）〜（３）、（１１）及び（１２）に記載の効果に加えて以下の効果を得ることができる。延設部６２に係合凹条６２ａを凹設するとともに、外側部材６４を円環状に形成し、その外側部材６４の内周面に係合突部６４ａを突設した。そのため、螺合部材６３を延設部６２に螺着するときの内側部材６１の回転防止を簡易な構成で形成することができる。また、ガイド部材６９を延設部６２に螺着することにより、そのガイド部材６９によってユニットバス壁１５の外側から延設部６２内へ通水管１６を案内することができる。一方、ユニットバス壁１５の裏側が狭い場合は、ガイド部材６９を延設部６２から取り外せばよいため、貫通部Ｋの形成場所に対応することができる。
【００７６】

The guide portion 31 has an upper end opened to one end of the connecting cylinder portion 30 and a lower end opened downward. The guide portion 31 guides the water pipe 16 inserted from the lower end side of the guide portion 31 into the connecting cylinder portion 30 and further into the extending portion 26.
[0034]
Further, a connecting portion 36 for connecting a synthetic resin sheath tube 35 is connected to the lower end portion of the guide portion 31. As shown in FIG. 1, an engaging ridge 37 projects inwardly on the inner peripheral edge of the upper end of the connecting portion 36, and the engaging ridge 37 is formed on the outer peripheral surface of the tip of the guide portion 31. The connecting portion 36 is connected to the guide portion 31 by engaging with the engaging recess 31b.

Then, the sheath tube 35 is inserted into the connecting portion 36, and the locking claw 38 is locked to the outer peripheral surface of the sheath tube 35, whereby the sheath tube 35 is connected to the guide portion 31 through the connecting portion 36. The
[0035]
The screwing member 23 is formed in a cylindrical shape from a synthetic resin material, and a screw thread 23a that can be screwed into the second screw portion 26c is threaded on the inner peripheral surface thereof. A packing P as a seal member is disposed between the inner surface of the unit bath wall 15 and the water stop portion 25. The packing P is formed in an annular shape from a rubber material.
[0036]
In order to form the penetrating part K in the unit bus wall 15 using the penetrating part forming apparatus 20, first, the packing P is extended on the inner member 21 disposed inside the unit bus wall 15. Extrapolated to section 26. As shown in FIGS. 4 and 5, the outer member 22 is disposed outside the unit bus wall 15 so that the insertion hole 34 matches the through hole 15a, and the extended portion 26 into which the packing P is extrapolated is provided as a unit. The second screw portion 26 c is exposed to the outside of the outer member 22 by being inserted from the inside of the bus wall 15 into the through hole 15 a and further into the insertion hole 34. In a state where the extended portion 26 is inserted into the insertion hole 34, the cylindrical portion 24 extends obliquely upward. Then, the screwing member 23 is screwed into the screw thread 23 a from the outside of the unit bus wall 15, and the screwing member 23 is screwed to the extending portion 26. At this time, the rotation of the screwing member 23 causes the inner member 21 to rotate via the extending portion 26. However, since the engaging surface 26a engages with the engaging portion 33a, the rotation is restricted. Therefore, the screwing member 23 is screwed to the extending portion 26 with the cylindrical portion 24 being disposed obliquely upward.
[0037]
As the screwing member 23 is screwed into the second screw portion 26c, the end surface of the screwing member 23 comes into contact with the second flange portion 32b, and the outer member 22 is pushed toward the unit bus wall 15 side. Further, the inner member 21 and the screwing member 23 are attracted to each other, and the inner member 21 is attracted to the unit bus wall 15 side. At this time, since the inner member 21 is pulled toward the unit bus wall 15 side by the rotation of the screwing member 23, the entire inner member 21 is pulled toward the unit bus wall 15 side. Moreover, the water stop part 25 is not drawn locally to the unit bath wall 15 side, but the entire water stop part 25 is drawn to the unit bath wall 15 side via the extending part 26. Therefore, in the state where the entire periphery of the water stop portion 25 presses the packing P toward the unit bath wall 15, the entire end surface of the packing P presses against the inner surface of the unit bath wall 15 which becomes the peripheral portion of the through hole 15 a. ing.
[0038]
The unit bath wall 15 is sandwiched between the water stop portion 25 and the screwing member 23 via the outer member 22 and the packing P, and the inner member 21 and the outer member 22 are attached to the unit bus wall 15. That is, the water stop 25 and the screwing member 23 sandwich the unit bath wall 15 with an equal force, and the through-hole K is formed in the unit bus wall 15. Thereafter, the caulking process is performed on the outer periphery of the packing P between the inner surface of the unit bath wall 15 and the water stop portion 25, and the decorative plate 27 is mounted on the outer periphery of the cylindrical portion 24. The coking operation is not necessarily performed and may be omitted.
[0039]
Subsequently, in the decorative plate 27, the locking recess 27c and the locking rib 24c are locked, and the decorative plate 27 is moved to the unit bath wall 15 side. Then, the waterproof part 25 is covered with the decorative cover 27a, and the cylindrical part 24 closer to the waterproof part 25 than the first screw part 24a is covered with the decorative cylinder part 27b. As a result, the caulking is covered with the decorative cover 27a, and it is possible to prevent the problem that the appearance is deteriorated due to the exposure of the caulking or to prevent the caulking from being deteriorated.
[0040]
Next, in the outer member 22, the sheath pipe 35 is connected to the connecting portion 36, and the pair of water pipes 16 are inserted into the sheath pipe 35. These water pipes 16 are guided obliquely upward by the inner peripheral surface of the guide portion 31, and are guided to the insertion passage 24 b in the cylindrical portion 24 by the guide path 26 b in the extension portion 26. Further, the water passage 16 is guided by the insertion passage 24 b so as to extend obliquely upward with respect to the axis of the extending portion 26, and is sent out from the inside of the tubular portion 24 to the outside of the inner member 21.
[0041]
At this time, since the feeding operation is performed in a state where the pair of water pipes 16 are bent by the guide part 31, the guide part 31 and the extension part 26 are caused by the force of the water pipe 16 returning to a straight shape from the curved state. The cylindrical portion 24 is pushed upward from the inside. However, since the entire inner member 21 is pulled toward the unit bath wall 15 by the screwing member 23, the inner member 21 is prevented from being separated from the unit bath wall 15 by the pressure of the water pipe 16. .
[0042]
Next, the mounting nut 28 and the drawing member 29 are assembled by fitting the frame-shaped portion 29 b into the fitting groove 28 a. Then, the pair of water pipes 16 are inserted inside the mounting nut 28 to which the drawing member 29 is attached. Further, after the water pipe 16 is inserted into the outlet 29c, it is pulled out from the inside of the drawing member 29 to the outside thereof. At this time, since the inner peripheral surface of the outlet 29c is in pressure contact with the outer peripheral surface of the water conduit 16, a water stop structure is formed between the inner peripheral surface of the outlet 29c and the outer peripheral surface of the water conduit 16. Then, when only the mounting nut 28 is rotated and the inner peripheral screw portion 28b is screwed to the first screw portion 24a, the drawing member 29 is screwed to the cylindrical portion 24 in a state of being pressed toward the cylindrical portion 24 side. . In the screwed state of the pull-out member 29, only the pull-out member 29 can be rotated in the circumferential direction, and the position of the pair of pull-out ports 29c can be adjusted vertically and horizontally.
[0043]
As shown in FIG. 1, when the mounting nut 28 is screwed to the cylindrical portion 24, the drawer member 29 is attached to the inner member 21, and the outlet 29 c is obliquely upward at the upper end portion of the inner member 21. It is arranged to extend. Therefore, the water pipes 16 drawn out from the respective outlets 29c are arranged so as to extend obliquely upward from the inner side of the inner member 21. As a result, a penetrating portion K is formed in the unit bath wall 15 by the inner member 21, the outer member 22, the extending portion 26, and the screwing member 23, and the water pipe 16 passes through the unit bath wall 15 from the outside of the unit bath wall 15. It is disposed through. Further, the water pipes 16 are respectively disposed up to the bathtub 14 and connected to a faucet device (not shown) for supplying hot water.
[0044]
In a state where the penetration portion K is formed in the unit bath wall 15, for example, when water is used inside the unit bath wall 15 and the penetration portion K is covered with water, the inner peripheral surface and the frame-like portion of the fitting groove 28a. Water is prevented from entering the inner member 21 from between the outer peripheral surface of the upper end edge of 29 b and between the inner peripheral surface of the outlet 29 c and the outer peripheral surface of the water conduit 16. The packing P is in close contact with the inner surface of the unit bath wall 15 and the end surface of the water stop portion 25 of the inner member 21, and the water stop portion 25 and the unit bath wall 15 are caulked. Therefore, water can be prevented from entering the inner member 21 from between the water stop portion 25 and the unit bath wall 15, and water can be prevented from leaking to the outside of the unit bath wall 15 from the through hole 15 a.
[0045]
According to the above embodiment, the following effects can be obtained.
(1) The inner member 21 is disposed inside the unit bus wall 15, and an extending portion 26 extending from the inner member 21 extends through the unit bus wall 15 to the outside of the unit bus wall 15. The screwing member 23 is screwed to the extending portion 26. Therefore, the entire inner member 21 can be drawn toward the unit bath wall 15 by the screwing of the screwing member 23 to the extending portion 26, and the entire water stop portion 25 can be pressed against the packing P with an equal force. In other words, the water stop portion 25 via the packing P and the screwing member 23 via the outer member 22 sandwich the unit bath wall 15 from the inside and outside of the unit bath wall 15 with equal force, and pass through the portion. K can be formed. As a result, the pressure contact surface between the packing P and the unit bath wall 15 does not cause a difference in the degree of pressure contact, and it is possible to eliminate the possibility that water leaks out of the unit bath wall 15 from a location where the pressure contact is weak. Moreover, since water leakage can be prevented as described above, the caulking work between the water stop part 25 and the unit bath wall 15 is not indispensable, and the work for forming the penetration part K is simplified. Can do.
[0046]
(2) The penetrating portion K is formed in the unit bus wall 15 by passing through the unit bus wall 15 and screwing the screwing member 23 into the extending portion 26 of the inner member 21. In other words, in addition to the through hole 15 a, no hole that penetrates the unit bus wall 15 is formed in the through part K, and no hole for inserting a screw is formed in the member that forms the through part K. Accordingly, unlike the conventional case where a hole for inserting a screw is formed in a member for forming the through portion K, the inner side and the outer side of the unit bus wall 15 are not communicated by a hole other than the through hole 15a. . As a result, it is possible to eliminate the possibility that water flows through the holes other than the through holes 15 a and the water flows through the inside and outside of the unit bath wall 15.
[0047]
(3) By screwing the screwing member 23 into the extending portion 26 penetrating the through hole 15a, the penetrating portion K is formed in the unit bus wall 15. Therefore, the penetration part K can be formed if the water stop part 25 and the first flange part 32a through the packing P have an area sufficient to press contact with the peripheral part of the through hole 15a. Moreover, since it is not necessary to penetrate the screw into the through hole 15a, the through hole 15a of the present embodiment can be made smaller in diameter than the through hole formed when the conventional through part is formed. Therefore, in the conventional member that forms the penetrating portion, the portion disposed at the periphery of the through hole 15a needs to have a size that allows the screw to be inserted and has a strength that can withstand the tightening force of the screw. Unlike the case, in this embodiment, the inner member 21 and the outer member 22 can be reduced in size. Further, since no screws are used, the screws are not rusted, and the possibility of rusting in the penetrating portion K can be eliminated.
[0048]
(4) A threaded member 23 is screwed from the outside of the unit bus wall 15 to the extending portion 26 that extends to the outside of the unit bus wall 15 to form a through portion K. Therefore, in the formation work of the penetration part K, it is not necessary to rotate the inner member 21, it is not necessary to consider the direction of the cylindrical part 24 due to the rotation of the inner member 21, and the formation work of the penetration part K can be performed. it can.
[0049]
(5) A guide path 26b is formed in the extended portion 26, and the guide path 26b communicates with the insertion path 24b. Therefore, the water pipe 16 guided to the extension part 26 by the guide part 31 can be guided into the inner member 21 by the guide path 26b, and the water pipe 16 is inserted into the inner member 21 to penetrate the penetration part K. Can be easily performed.
[0050]
(6) Since the extending portion 26 is integrally formed on the inner member 21, the forming operation of the penetrating portion K is performed as compared with the case where the tubular portion 24 and the extending portion 26 are formed separately. It can be done easily. Further, as in the case where the cylindrical portion 24 and the extending portion 26 are formed separately, there is no need to consider water leakage prevention at the connection portion between the cylindrical portion 24 and the extending portion 26, so that the penetration portion The configuration of K can be simplified.
[0051]
(7) The extended portion 26 can be inserted into the outer member 22 formed separately from the inner member 21, and the screw member 23 can be screwed into the extended portion 26 protruding from the outer member 22. Therefore, the outer member 22 is formed to be movable along the extending portion 26, and the outer member 22 can be moved to the unit bus wall 15 side by the screwing of the screwing member 23 to the extending portion 26. The screwing distance of the screwing member 23 to the second screw portion 26c can be increased. Therefore, the inner member 21 can be firmly fixed to the unit bus wall 15 by the screwing member 23, and the screwing member 23 can be securely screwed to the extending portion 26.
[0052]
(8) The outer member 22 including the guide portion 31 is formed separately from the inner member 21, and the extending portion 26 is inserted into the outer member 22. Therefore, the outer member 22 can be brought close to the unit bus wall 15 by screwing the screwing member 23 into the extending portion 26. That is, the guide part 31 can be disposed along the wall surface of the unit bath wall 15, and when the water pipe 16 is inserted into the through hole 15 a and the insertion passage 24 b from the inside of the guide part 31, the water pipe 16 is arranged in its axis. The amount of bending along the direction can be reduced, and the insertion operation can be facilitated.
[0053]
(9) The penetration member K is formed with the outer member 22 interposed between the inner member 21 and the screwing member 23. Therefore, the outer member 22 exhibits a washer-like function, and the screwing member 23 can be made difficult to loosen. Therefore, it is possible to maintain the state where the water stop portion 25 is in pressure contact with the packing P.
[0054]
(10) Due to the engagement between the engagement surface 26a and the engagement portion 33a, the inner member 21 can be prevented from rotating as the screw member 23 is screwed with respect to the extending portion 26. Therefore, after the inner member 21 is disposed so that the cylindrical portion 24 extends obliquely upward, the inner member 21 is held by hand so that the cylindrical portion 24 does not rotate during the screwing operation of the screwing member 23. There is no need to do so, and the formation of the penetrating portion K can be easily performed. In particular, the screwing member 23 can be screwed into the extending portion 26 in a state where the cylindrical portion 24 is maintained so as to extend obliquely upward from the inner surface of the unit bus wall 15. Therefore, the formation work of the penetration part K can be easily performed in consideration of the drawing direction of the subsequent water flow pipe 16.
[0055]
(11) A guide portion 31 is provided outside the unit bus wall 15, and the guide portion 31 extends into the extension portion 26 so as to extend obliquely with respect to the wall surface of the unit bus wall 15, and the guide path 26 b. Communicating with Therefore, the water guide pipe 16 can be promptly guided into the extended portion 26 by the guide portion 31, and the subsequent insertion operation into the inner member 21 can be easily performed.
[0056]
(12) Since the connecting portion 36 is formed in the guide portion 31, the sheath tube 35 can be easily connected to the guide portion 31 by the connecting portion 36.
