Description

【０００１】
【発明の属する技術分野】
本発明は、鉄筋コンクリート建物の開口部に取付けるための鉄筋コンクリート用サッシ枠を備えたサッシに関する。
【０００２】
【従来の技術】
従来、上枠と下枠と左右の縦枠を方形状に組立てたサッシ枠に障子を装着したサッシが種々提案されている。
このサッシは、そのサッシ枠を建物の開口部に取付けることで建物に取付ける。
前記サッシ枠は木造建物に取付ける木造用や鉄筋コンクリート建物に取付ける鉄筋コンクリート用などがある。
前記木造用サッシ枠は、その枠材が取付片を備えた形態で、その取付片を開口部周縁に固着具で固着して取付ける。
前記鉄筋コンクリート用サッシ枠は、その枠材がアンカー金具取付部を備えた形態で、そのアンカー金具取付部に取付けたアンカー金具を鉄筋コンクリートに埋設けたアンカーに溶接して固着して取付けている。
【０００３】
前述のように、木造用サッシ枠と鉄筋コンクリート用サッシ枠は、その枠材の形態が相違するから鉄筋コンクリート用サッシ枠を木造建物の開口部には取付けしづらい。
また、鉄筋コンクリート用サッシ枠はアンカー金具とアンカーが溶接してあるから、一度取付けたサッシ枠を取り外すのが大変面倒である。
【０００４】
これらのことを解消できるサッシが特許文献１に開示されている。
このサッシは、鉄筋コンクリート建物の開口部内面にベース部材をそれぞれ取付け、このベース部材と鉄筋コンクリート用サッシ枠を係止金具で連結したものである。
【０００５】
【特許文献１】
実用新案登録第２５５１２８４号公報
【０００６】
【発明が解決しようとする課題】
前述のサッシであれば、ベース部材と鉄筋コンクリート用サッシ枠の係止を解除することでサッシ枠を簡単に取り外しできる。
しかし、前述のサッシ枠は、その枠材が係止部を有し、その係止部に係止金具を係止するようにしてあるから、枠材の形態が通常一般の鉄筋コンクリート用サッシ枠の枠材の形態と相違し、通常一般の鉄筋コンクリート用サッシ枠は取付けできない。
【０００７】
本発明は、前述の課題に鑑みなされたものであって、その目的は、通常一般の鉄筋コンクリート用サッシ枠を建物の開口部に取付けできると共に、その鉄筋コンクリート用サッシ枠を簡単に取り外しできるサッシを提供することである。
【０００８】
【課題を解決するための手段】
第１の発明は、上枠と下枠と左右の縦枠で方形状の鉄筋コンクリート用サッシ枠と、
上横材と左右の縦材で下向きコ字状であって、前記上枠・左右の縦枠に取付けられる水密用枠と、
建物の開口部における下内面に取付けられる下地材と、
上横取付用枠材と左右の縦取付用枠材で下向きコ字形状であって、前記建物の開口部における上内面と左右の縦内面に取付けられる建物取付用枠を備え、
前記水密用枠と前記建物取付用枠が係脱自在に水密して連結され、
前記上枠と上横取付用枠材が着脱自在に固着され、前記縦枠と縦取付用枠材が着脱自在に固着され、前記下枠と下地材が着脱自在に固着されていることを特徴とするサッシである。
【０００９】
第２の発明は、第１の発明において下地材と建物取付用枠を建物の開口部に取付けた状態で、水密用枠を取付けた鉄筋コンクリート用サッシ枠を室外から室内に向けて移動することで、上枠の取付部と左右の縦枠の取付部が建物取付用枠の枠取付部にそれぞれ接し、下枠の取付部が下地材の枠取付部に接すると共に、水密用枠が建物取付用枠に水密して突き合せ連結される形態で、
前記各取付部と各枠取付部がビスでそれぞれ固着されているサッシである。
【００１０】
第３の発明は、第２の発明において水密用枠の上横材、左右の縦材は、上枠・左右の縦枠の室外側部にビスで固着される取付部と水密部を有し、その水密部に乾式の水密材が設けてあり、
建物取付用枠の上横取付用枠材と左右の縦取付用枠材は、建物の開口部の上内面、左右の縦内面に固着具で固着される建物取付部と、上枠・縦枠の取付部がビスで固着される枠取付部と、水密部と、シール材装着部を有し、その水密部に乾式の水密材が設けてあると共に、シール材装着部に乾式のシール材が装着され、前記水密用枠の各水密部と前記建物取付用枠の各水密部は、水密用枠を室外から室内に向けて移動することで水密材を介して突き合せ連結される形態で、
前記シール材によって建物の開口部と建物取付用枠との間を水密するようにしたサッシである。
【００１１】
第４の発明は、第１の発明において建物の開口部が、既設サッシの既設サッシ枠であるサッシである。
【００１２】
第５の発明は、第４の発明において既設サッシ枠は上横枠材と下横枠材と左右の縦枠材で方形状で、その各内面は平坦面に処理され、
前記上横枠材の内面に上横取付用枠材が固着され、前記下横枠材の内面に下地材が固着され、前記縦枠材の内面に縦取付用枠材が固着されているサッシである。
【００１３】
【作　用】
第１の発明によれば、建物の開口部に取付けた建物取付用枠、下地材と鉄筋コンクリート用サッシ枠の上枠、縦枠、下枠が着脱自在に固着され、その上枠・左右の縦枠に取付けた水密用枠が前記建物取付用枠に係脱自在に水密して連結されているので、建物取付用枠、下地材を取付けた状態で鉄筋コンクリート用サッシ枠を水密用枠とともに取り外しできる。
しかも、鉄筋コンクリート用サッシ枠に水密用枠を取付けたので、その鉄筋コンクリート用サッシ枠は通常一般のものを用いることができる。
したがって、通常一般の鉄筋コンクリート用サッシ枠を建物の開口部に取付けできると共に、その鉄筋コンクリート用サッシ枠を簡単に取り外しできる。
【００１４】
第２の発明によれば、建物の開口部に下地材と建物取付用枠を取付けた状態で、水密用枠を取付けた鉄筋コンクリート用サッシ枠を室外から室内に向けて移動し、その後にビス止めすることで取付けできる。
しかも、ビスを弛めることで水密用枠とともに鉄筋コンクリート用サッシ枠を室外に向けて移動することで取り外しできる。
したがって、鉄筋コンクリート用サッシ枠の取り付け、取り外しが容易である。
【００１５】
第３の発明によれば、水密用枠が上枠、縦枠の室外側部にしっかりと取付けられると共に、建物取付用枠が建物の開口部の上内面、縦内面にしっかりと取付けられるので、鉄筋コンクリート用サッシ枠を強固に取付けできる。
また、建物取付用枠の各水密部と水密用枠の各水密部は２つの水密材で二重シールされるから、水密が優れたものである。
また、建物の開口部と建物取付用枠との間がシール材で水密される。
しかも、前述の水密材、シール材は乾式であるから施工性が良い。
【００１６】
第４の発明によれば、既設サッシの既設サッシ枠を利用して新設のサッシに改装できる。
【００１７】
第５の発明によれば、平坦面に処理された上横枠材の内面、下横枠材の内面、縦枠材の内面（既設サッシ枠の内面）に上横取付用枠材、下地材、縦取付用枠材が固着されるので、既設サッシ枠の内面が凹凸であったとしても強固に取付けできる。
【００１８】
【発明の実施の形態】
図１と図２に示すように、建物の開口部１に鉄筋コンクリート用サッシ枠２を取付け、その鉄筋コンクリート用サッシ枠２に図示しない障子、パネルを装着してサッシとしてある。
この実施の形態では鉄筋コンクリートの建物壁体３の開口部３ａに既設サッシ枠４が取付けてあり、この既設サッシ枠４が建物の開口部１を形成している。なお、以下の説明では鉄筋コンクリート用サッシ枠２をただ単にサッシ枠２とする。
【００１９】
前記既設サッシ枠４は上横枠材５、下横枠材６、左右の縦枠材７で方形状である。
前記上横枠材５は木製で、その内面５ａに障子ガイド用の凹溝５ｂを長手方向に連続して有する。
サッシ枠２を取付ける場合にはこの凹溝５ｂに部材５ｃが嵌め込まれて内面５ａは凹凸のない平坦面である。この部材５ｃは木製である。
前記下横枠材６は木製で、内面６ａは斜めであると共に、その内面６ａには仮想線で示すようにレール６ｂが取付けてあるが、サッシ枠２を取付ける場合には取り外すことで平坦面とする。このレール６ｂは金属レールである。
前記縦枠材７は木製で、内面７ａに戸当り用の凹溝７ｂが長手方向に連続して有する。サッシ枠２を取付ける場合にはこの凹溝７ｂに部材７ｃが嵌め込まれて内面７ａは凹凸のない平坦面である。この部材７ｃは木製である。
つまり、既設サッシ枠４の上横枠材５、下横枠材６、縦枠材７の内面は凹凸があるので、その内面を平坦面に処理する。
【００２０】
すなわち、この実施の形態は既設の木製サッシの既設サッシ枠４を残存して新設のサッシのサッシ枠２を取付けた改装サッシである。
【００２１】
前記サッシ枠２は下地材１０と水密用枠２０と躯体取付用枠３０を介在して前述の開口部１に取付けられる。
前記サッシ枠２は上枠１１と下枠１２と左右の縦枠１３で方形状で、その内部に図示しない内障子、外障子が引き違いに装着される。前記上枠１１、下枠１２、縦枠１３はアンカー金具取付部を有し、かつアルミ製である。
【００２２】
前記上枠１１は図３に示すように、面外方向に向う枠本体１１ａの室内側部に室内側鉤片１１ｂ、室外側部に室外側鉤片１１ｃを一体に備え、その各鉤片にアンカー金具を係止して取付けるようにしてある。
つまり、上枠１１は通常一般の鉄筋コンクリート用上枠である。
前記上枠１１は取付部を有する。例えば、前記室内側鉤片１１ｂの縦片が室内側の取付部としてある。
【００２３】
前記下枠１２は図４に示すように、枠本体１２ａの室内側部に室内側鉤片１２ｂ、室外寄りに室外側鉤片１２ｃを一体に備え、その各鉤片にアンカー金具を係止して取付けるようにしてある。
つまり、下枠１２は通常一般の鉄筋コンクリート用下枠とほぼ同様である。
前記下枠１２は取付部、例えば室内側の取付部１４と室外側の取付部１５を有し、その室外側の取付部１５は室内側の取付部１４よりも下方に突出している。例えば、前記室内側鉤片１２ｂを形成する縦片が室内側の取付部１４で、枠本体１２ａの室外寄りに一体に設けた垂下片が室外側の取付部１５である。
【００２４】
前記縦枠１３は図５に示すように、面外方向に向う枠本体１３ａの室内側部と室外側部に室内側鉤片１３ｂと室外側鉤片１３ｃをそれぞれ一体に備え、その各鉤片にアンカー金具を係止して取付けるようにしてある。
つまり、縦枠１３は通常一般の鉄筋コンクリート用縦枠である。
前記縦枠１３は取付部を有する。例えば室内側鉤片１３ｂの外向片が室内側の取付部としてある。
これによって、前述のサッシ枠２は通常一般の鉄筋コンクリート用サッシ枠である。
【００２５】
前記下地材１０は開口部１の下内面、例えば下横枠材６の内面６ａに固着される。
この下地材１０は、図４に示すようにサッシ枠２の下枠１２が室外側から室内側に向けて移動することで取付け可能な形態である。
また、前記下地材１０は枠取付部を有する。例えば室内側枠取付部１０ａと室外側枠取付部１０ｂを有する。
前記室内側枠取付部１０ａは室外側枠取付部１０ｂよりも内方に突出し、下枠１２を室外側から室内側に向けて移動することで下枠１２の室内側の取付部１４、室外側の取付部１５を各枠取付部１０ａ，１０ｂに当接できるようにしてある。
【００２６】
例えば、下地材１０は上向きコ字形状の第１下地材１０−１と、ほぼクランク形状の第２下地材１０−２で中空部を有する形態で、第１下地材１０−１が固着具１６で下横枠材６の内面６ａに固着される。第１・第２下地材１０−１、１０−２の室内側縦片が室内側枠取付部１０ａを形成し、第１・第２下地材１０−１、１０−２の室外側縦片が室外側枠取付部１０ｂを形成している。
【００２７】
前記水密用枠２０は、図１と図２に示すように上横材２１と左右の縦材２２で下向きコ字状である。
前記上横材２１は上枠１１、好ましくは上枠１１の室外側部に固着される取付部２１ａと、この取付部２１ａと連続した水密部２１ｂを有する。この水密部２１ｂには乾式の水密材２３が設けてある。
前記水密部２１ｂは上枠１１よりも外側に突出し、好ましくは上枠１１よりも外側及び室外側に突出している。前述の上枠１１よりも外側に突出するとは、上枠１１の外面よりも面内方向外側に突出することで、前述の上枠１１よりも室外側に突出するとは、上枠１１の室外側面よりも室外側に突出することである。
【００２８】
具体的には図３に示すように、取付部２１ａは室外側鉤片１１ｃの横向片にビス２４で固着され、水密部２１ｂは室内側に開口した凹部２５と室内側に向う突片２６を有し、その凹部２５に水密材２３が設けてある。
【００２９】
前記縦材２２は縦枠１２、好ましくは縦枠１２の室外側部に固着される取付部２２ａと、この取付部２２ａと連続した水密部２２ｂを有する。この水密部２２ｂには乾式の水密材２３が設けてある。
前記水密部２２ｂは縦枠１２よりも外側に突出し、好ましくは縦枠１２よりも外側及び室外側に突出している。前述の縦枠１２よりも外側に突出するとは縦枠１２の外面よりも面内方向外側に突出することで、前述の縦枠１２よりも室外側に突出するとは、縦枠１２の室外側面よりも室外側に突出することである。
【００３０】
具体的には図５に示すように、取付部２２ａは室外側鉤片１３ｃの横向片にビス２４で固着され、水密部２２ｂは室内側に開口した凹部２５と室内側に向う突片２６を有し、その凹部２５に水密材２３が設けてある。
つまり、この実施の形態では上横材２１と縦材２２は同一部材である。これに限ることはなく別部材であっても良い。
【００３１】
前記建物取付用枠３０は図１・図２に示すように、上横取付用枠材３１と左右の縦取付用枠材３２で下向きコ字形状で、下地材１０を取付けた状態で建物の開口部１内に室内側から挿入可能な形態である。
前記上横取付用枠材３１は図１と図３に示すように、開口部１の上内面、例えば上横枠材５の内面５ａに固着される建物取付部３１ａと、上枠１１に固着される枠取付部３１ｂと、前記上横材２１の水密部２１ｂに水密して係脱自在に連結する水密部３１ｃと、シール材装着部３１ｄを有する。この水密部３１ｃには乾式の水密材３３が設けられ、シール材装着部３１ｄには乾式のシール材３４が装着される。
前記建物取付部３１ａが室内外側方向の中間で、枠取付部３１ｂが室内側で、水密部３１ｃが室外寄りで、シール材装着部３１ｄが室外側であることが好ましいが、これに限ることはない。
また、前記水密部３１ｃは建物取付部３１ａよりも内側に突出しているが、これに限ることはない。
【００３２】
前記上取付用枠材３１は図３に示すように、室内外側方向に向う基板３５と室内側の下向片３６と室外側の上向片３７でほぼクランク形状で、その基板３５が建物取付部３１ａで、下向片３６が枠取付部３１ｂで、上向片３７の突出端部に室内側に向うあり溝が形成されてシール材装着部３１ｄとしてある。
前記水密部３１ｃは室外側に開口した凹部３８と室外側に向う突片３９を備え、この突片３９が上横枠２１の凹部２５と対向し、凹部３８が上横材２１の突片２６と対向する。凹部３８に水密材３３が設けてある。
【００３３】
前記シール材３４は、装着部３４ａと、この装着部３４ａと連続した一次シール部３４ｂと、その一次シール部３４ｂと連続しかつ面内方向の外側に向う二次シール部３４ｃを有する。
前記二次シール部３４ｃは一次シール部３４ｂに対して室内側方向に向けて斜めで、一次シール部３４ｂと二次シール部３４ｃは外力が作用しない状態で、ほぼく字形状である。好ましくは、一次シール部３４ｂは厚肉の板状で、二次シール部３４ｃは薄肉の舌片状である。
【００３４】
前記縦取付用枠材３２は図２と図５に示すように、開口部１の縦内面、例えば縦枠材７の内面７ａに固着される建物取付部３２ａと、縦枠１２に固着される枠取付部３２ｂと、前記縦材２２の水密部２２ｂに水密して係脱自在に連結する水密部３２ｃと、シール材装着部３２ｄを有する。前記水密部３２ｃには乾式の水密材３３が設けられ、シール材装着部３２ｄには乾式のシール材３４が装着される。前記水密部３２ｃは建物取付部３２ａよりも内側に突出しているが、これに限ることはない。
前記建物取付部３２ａが室内外側方向の中間で、枠取付部３２ｂが室内側で、水密部３２ｃが室外寄りで、シール材装着部３２ｄが室外側であることが好ましいが、これに限ることはない。
【００３５】
前記縦取付用枠材３２は図５に示すように、室内外側方向に向う基板４０と室内側の内向片４１と室外側の外向片４２でほぼクランク形状で、その基板４０が建物取付部３２ａで、内向片４１が枠取付部３２ｂで、外向片４２の突出端部に室内側に向うあり溝が形成されてシール材装着部３２ｄとしてある。
前記水密部３２ｃは室外側に開口した凹部４３と室外側に向う突片４４を備え、この突片４４が縦材２２の凹部２５と対向し、凹部４３が縦材２２の突片２６と対向する。この凹部４３に水密材３３が設けてある。
つまり、この実施の形態では前記上横取付用枠材３１と縦取付用枠材３２は同一部材である。これに限ることはなく別部材であっても良い。
【００３６】
前記縦取付用枠材３２のシール材装着部３２ｄに装着したシール材３４は、前述の上取付用枠材３１のシール材装着部３１ｄに装着したシール材３４と同一である。
【００３７】
次に、サッシ枠２の取付けについて説明する。
建物の開口部１の下内面に下地材１０を取付ける。
なお、木製サッシを改装する場合には、既設サッシ枠４から障子を取り外し、前述のように各凹溝５ｂ，７ｂに部材５ｃ，７ｃをそれぞれ嵌め込み、下横枠材６からレール６ｂを取り外しする。つまり、内面を平坦面に処理する。
そして、下横枠材６の内面６ａに下地材１０を取付ける。
この下地材１０は開口部１の左右開口寸法よりも小さく、その下地材１０の長手方向両端面が左右の内面と離隔して取付けられる。つまり、この下地材１０の長さは下枠１２の長さと同一、又は短かい。
【００３８】
前記上横取付用枠材３１と左右の縦取付用枠材３２を連結して下向きコ字状の建物取付用枠３０とし、水密材３３を設けると共に、シール材３４を装着する。前述の建物取付用枠３０を開口部１に室外側から挿入して各建物取付部３１ａ，３２ａを開口部１の上内面（例えば、上横枠材２の内面２ａ）、左右の縦面（例えば、縦枠材７の内面７ａ）に固着具４５でそれぞれ固着する。この実施の形態ではスペーサ４５ａを介して取付けてある。
これによって、各シール材３４が建物の開口部１における上開口縁室外側面（例えば上横枠材５の室外側面と建物壁体３の室外側面）及び左右開口縁室外側面（例えば、縦枠材７の室外側面と建物壁体３の室外側面）にそれぞれ圧接し、建物取付用枠３０と建物の開口部１との間を水密する。
また、左右の縦取付用枠材３２の下端部は前述した開口部１の下内面、例えば下横枠材６の上面６ａと離隔し、かつ下地材１０とは干渉しない。
【００３９】
上横材２１と左右の縦材２２を連結して下向きコ字形状の水密用枠２０を組立る。
この水密用枠２０をサッシ枠２の上部と左右縦部、つまり上枠１１と左右の縦枠１２に取付ける。
前述の水密用枠２０を備えたサッシ枠２を室外側から室内側に向けて移動して建物取付用枠３０と下地材１０で囲まれた空間内に挿入する。
【００４０】
これによって、水密用枠２０のシール部２１ｂ，２２ｂと建物取付用枠３０のシール部３１ｃ，３２ｃが水密材２３，３３を介在して突き合せ連結される。例えば、水密用枠２０の突片２６が建物取付用枠３０の凹部３８，４３に設けたシール材３３に圧接し、建物取付用枠３０の突片３９，４４が水密用枠２０の水密材２３に圧接する。
よって、上枠１１と上横取付用枠材３１との間が水密されると共に、左右の縦枠１２と左右の縦取付用枠材３２との間が水密される。
【００４１】
これと同時に、上枠１１の取付部、例えば室内側の鉤片１１ｂの縦片が上横取付用枠材３１の枠取付部３１ｂに当接し、左右の縦枠１３の取付部、例えば室内側の鉤片１３ｂの外向片が左右の縦取付用枠材３２の枠取付部３２ｂに当接し、下枠１２の室内側の取付部１４、室外側の取付部１５が下地材１０の室内側枠取付部１０ａ、室外側枠取付部１０ｂに当接する。
前述の各当接部をビス４６でそれぞれ固着し、上枠１１と上横取付用枠材３１、下枠１２と下地材１０、左右の縦枠１３と左右の縦取付用枠材３２がそれぞれ連結される。
【００４２】
よって、ビス４６を弛めることでサッシ枠２を水密用枠２０とともに取り外しできる。
また、建物取付用枠３０と建物の開口部１の上、左右開口縁室外側面とが乾式のシール材３４で水密され、建物取付用枠３０と水密用枠２０が乾式の水密材２３，３３で水密されるので、水密作業が簡単であり、サッシ枠の施工性が良い。
【００４３】
また、前述のシール材３４は一次シール部３４ｂと二次シール部３４ｃを有し、外力が作用しない状態ではほぼく字形状であるから、前述の建物の開口部１の上、左右開口縁室外側面が平坦面ではなく階段形状であっても確実に水密できる。例えば、既設サッシ枠４（上横枠材５、縦枠材７）が建物壁体３よりも室外側に突出した階段形状であっても、その一次シール部３４ｂが既設サッシ枠４の室外側面（上横枠材５の室外側面、縦枠材７の室外側面）に圧接し、二次シール部３４ｃが建物壁体３の室外側面に圧接して確実に水密できる。
【００４４】
また、図３に示すように上横取付用枠材３１の室外側部分内面に結露が発生するが、その結露水は、上取付用枠材３１における水密部３１ｃよりも室内寄りの排水部４７で上枠１１に流れ落ちる。この排水部４７は前述の上横取付用枠材３１に形成した凹溝４７ａの底部に排水穴４７ｂを形成したもので、結露水を凹溝４７ａに集水し、排水穴４７ｂから上枠１１の室外側寄りに流れ落ちる。
この上枠１１の室外側寄り、詳しくは本体部１１ａの室外側寄りには結露排水弁４８が設けてあり、この結露排水弁４８から流れ落ちる。例えば、サッシ枠２に装着した外障子よりも室外寄りに流れ落ちる。
よって、前述の上横取付用枠材３１の室外側部分内面に発生した結露水が室内側まで流れ込むことがない。
なお、前述の結露排水弁４８は外気が吹き込むことがないと共に、結露水が流れ出る従来一般的に知られているものであるから、具体形状の説明を省略する。
【００４５】
前述の実施の形態によれば、木製の既設サッシを新設のサッシに簡単に改装することができる。
すなわち、木製の既設サッシから障子を取り外し、その既設サッシ枠４の内面を前述のようにして平坦面に処理する。
この状態で、下地材１０と建物取付用枠３０を既設サッシ枠４の内面に取付け、その後に水密用枠２０を備えたサッシ枠２を取付けることで、木製の既設サッシを新設のサッシに改装できる。
【００４６】
なお、前述の実施の形態では下地材１０の室内側部と建物取付用枠３０の室内側部とにアングル材４９ａを介して額縁材４９ｂが取付けてある。
これによって、内観の見栄えを良くしている。
【００４７】
次に、本発明の第２の実施の形態を説明する。
この実施の形態は図６、図７に示すように、建物の開口部１をスチール製の既設サッシの既設サッシ枠５０としたものであって、サッシ枠２、下地材１０、水密用枠２０、建物取付用枠３０は前述の第１の実施の形態と同様である。
【００４８】
前記既設サッシ枠５０はスチール製の上横枠材５１と、スチール製の下横枠材５２と、スチール製の左右の縦枠材５３で方形状である。
前記上横枠材５１、下横枠材５２、縦枠材５３の内面は平坦面処理してある。前記上横枠材５１の平坦な内面に上横取付用枠材３１の建物取付部３１ａが固着してあり、縦枠材５３の平坦な内面に縦取付用枠材３２の建物取付部３２ａが固着してある。
前記下横枠材５２の平坦な内面に下地材１０が固着してある。
