Description

【０００１】
【発明の属する技術分野】
本発明は、制光体を備える照明器具に関する。
【０００２】
【従来の技術】
照明器具としては、従来、Ｖバネ受け部を有する本体と、Ｖバネを有する透光板等のアクセサリーとを備えたものが知られている。
【０００３】
本体は下面が開口した箱形に形成されている。アクセサリーは枠体に取付けられている。Ｖバネは枠体に取付けられている。Ｖバネ受け部は、Ｖバネを受容するバネ受け部と、このバネ受け部近傍から下方に延びて下端から挿入されたＶバネをバネ受け部まで案内する案内部材とを有している。案内部材の下端は、バネ受け部及び案内部材が取付けられている本体の下端近傍まで延びている。
【０００４】
この照明器具では、枠体を支えながらＶバネを手で挟んだ状態で、Ｖバネの棒バネ部分を案内部材の案内溝に下端から挿入し、挟んでいた手の力を緩めて枠体を本体側に上昇させることにより、本体にアクセサリーが取付けられる（例えば、特許文献１参照。）。

【０００６】
【発明が解決しようとする課題】
しかし、特許文献１の技術では、Ｖバネ受け部を本体に取付けるためにねじ止めや溶接等を必要とするので、Ｖバネ受け部の取付けが面倒である。
【０００７】
本発明は、上記課題に鑑みなされたものであり、制光体ホルダを器具本体に容易に取付けることができる照明器具を得ることにある。
【０００８】
【課題を解決するための手段】
請求項１に係る照明器具は、ランプと、前記ランプからの照射光を照射する開口部、この開口部の縁部に設けられ前記開口部を被うように配置される外枠式制光体を支持する制光体ホルダの一端部並びに前記開口部を塞ぐように配置される内枠式制光体の周りに設けられた係合片が夫々引掛け可能な複数の第１の引掛け孔、及び前記開口部と対向する奥壁に設けられ前記制光体ホルダの他端部が引掛け可能な複数の第２の引掛け孔を有する器具本体と、を具備していることを特徴とする。
【０００９】
請求項１の発明によれば、第１の引掛け孔に制光体ホルダの一端部を引掛けるとともに、第２の引掛け孔に制光体ホルダの他端部を引掛けることで、制光体ホルダを器具本体に取付けることができる。しかも、請求項１の発明によれば、第１の引掛け孔に開口部を塞ぐように配置される内枠式制光体の周りに設けられた係合片を引掛けることで、内枠式制光体を取付けることができる。
【００１０】
請求項２に係る発明の照明器具は、ランプと、このランプを収容し、一面に前記ランプからの照射光を照射する開口部が形成されているとともに、この開口部の縁部に複数の第１の引掛け孔を有し、且つ、前記開口部と対向する奥壁に複数の第２の引掛け孔を有する器具本体と、制光要素及びこの制光要素の周りに設けられた複数のＶ字状のばねを有する制光体と、前記器具本体の外側に向けて前記第１の引掛け孔を挿通し前記器具本体の側壁に引掛けられる第１の引掛け部、前記器具本体の外側に向けて前記第２の引掛け孔を挿通し前記器具本体の奥壁に引掛けられる第２の引掛け部、及び前記器具本体の内側に向けて突設されて前記ばねが引掛け可能なばね受け部を備えて、前記器具本体に取付け可能に形成された複数の制光体ホルダと、を具備したことを特徴とする。
【００１１】
器具本体の第１及び第２の引掛け孔の数は複数であればいくつであってもよく、また、第１及び第２の引掛け孔を設ける位置はどこであってもよい。
【００１２】
制光体としては、開口部を被うように配置される外枠式制光体を好適に用いることができる。外枠式制光体は、例えば、枠体の内部に制光要素を設けるとともに、この枠体にＶ字状のばねを取付けることで形成することができる。
【００１３】
制光体ホルダは、１つの部材で形成しても複数の部材を連結させて形成してもよい。例えば、平板を所望の形状に抜き加工等で形成し、第１の引掛け部、第２の引掛け部、及びばね受け部を夫々折り曲げる等して形成してもよい。また、第１の引掛け部、第２の引掛け部、及びばね受け部を夫々別部材或いは一部別部材として所望の形状に抜き加工等で形成し、これらを溶接等で連結させて形成してもよい。また、ばね受け部には、例えばＶ字状のばねが引掛けられる。このばね受け部は、例えば所定間隔を隔てて向かい合わされた一対の切り起こし片（この根元部にＶ字状ばねが引掛けられる）で作ることもできる。また、ばね受け部は、Ｖ字状ばねが引掛けられる係止溝を有していてもよい。
【００１４】
請求項２の発明によれば、第１の引掛け部を第１の引掛け孔に挿通させてこの第１の引掛け部を器具本体の側壁に引掛けるとともに、第２の引掛け部を第２の引掛け孔に挿通させてこの第２の引掛け部を器具本体の奥壁に引掛けることで、制光体ホルダを器具本体に取付けることができる。
【００１５】
請求項３に係る発明の照明器具は、前記第１及び第２の引掛け孔が横長なスリット状に形成されているとともに、前記第１の引掛け孔がこの孔を塞ぐ第１の孔閉鎖部を開くことにより開口されるものであって、前記第１の孔閉鎖部が、前記第１の引掛け孔が有する一対の長辺の内の前記奥壁側の長辺上に設けられた第１の繋ぎ部のみで前記器具本体と繋がれており、前記第２の引掛け孔がこの孔を塞ぐ第２の孔閉鎖部を開くことにより開口されるものであって、前記第２の孔閉鎖部が、前記第２の引掛け孔が有する一対の長辺の内の前記器具本体の幅方向外側の長辺上に設けられた第２の繋ぎ部のみで前記器具本体と繋がれていることを特徴とする。
【００１６】
第１及び第２の繋ぎ部は1つあればよいが、第１及び第２の引掛け孔の大きさ（長さ）によっては複数設けてもよい。
【００１７】
請求項３の発明によれば、第１及び第２の引掛け孔を使用しないで照明器具を構成した場合に第１及び第２の引掛け孔が塞がれているので体裁がよい。
【００１８】
また、第１の孔閉鎖部は、第１の引掛け孔が有する一対の長辺のうちの第２の引掛け孔側の長辺上に設けられた第１の繋ぎ部で器具本体と繋がれており、第２の孔閉鎖部は、第２の引掛け孔が有する一対の長辺のうちの第１の引掛け孔側の長辺上に設けられた第２の繋ぎ部で器具本体と繋がれているため、第１及び第２の引掛け孔の長辺の縁にはばりが残らない。したがって、第１及び第２の引掛け部を第１及び第２の引掛け孔に良好に挿通させることができる。
【００１９】
【発明の実施の形態】
以下、図１〜図７を参照して本発明の一実施形態を説明する。
【００２０】
本実施形態に係る照明器具１は、例えば直管型蛍光ランプを光源とする埋め込み型の蛍光灯器具であって、一面を開口して使用したり、必要に応じて前記一面の開口部に制光体を取付けて使用したりするものである。
【００２１】
この照明器具１は、器具本体２、直管型蛍光ランプ（以下、単にランプという）２３、外枠式制光体３ａ、及び複数例えば４個の制光体ホルダ４等を具備している。
【００２２】
金属製の器具本体２は、相互間隔が広がる側壁２ａを、例えばこれらと一体の奥壁２ｂ（本実施形態では天板壁）で接続するとともに、長手方向両端に夫々端壁２ｃ（図２参照）を取付けることで、一面（本実施形態では下面）が開口する箱形状に形成されている。図２及び図４中符号２ｄは器具本体２の開口部を示している。この開口部２ｄには後述のランプ２３からの照射光が照射される。また、図３及び図４中符号１１は、器具本体２の長手方向中央部で背面（本実施形態では上面）を跨ぐように取付けられ、奥壁２ｂがその背面側に変形することを抑制するための補強ブリッジを示している。
【００２３】
図４に示すように、両側壁２ａの開口部側縁部２ｅは、外方に張り出し、且つ、断面コ字状の溝部をなして折り曲げられている。この溝部の内側に補強ブリッジ１１の端部が収容配置されている。なお、図２に示すように端壁２ｃの開口部側縁部２ｆも側壁２ａの開口部側縁部２ｅと同様に外方に張り出し、且つ、断面コ字状の溝部をなして折り曲げられている。
【００２４】
図３（Ａ）に示すように、奥壁２ｂの幅方向中央部且つ長手方向両端部には、天井などの器具固定部に器具本体２を固定するための取付け孔１２が開けられている。これら取付け孔１２には、図示しないが、天井裏取付けボルトの先端部が裏側から挿通される。そして、器具本体２内で取付けボルトに座金を嵌めるとともにナットを螺合して締めつけることにより、器具本体２がその開口部側縁部２ｅ，２ｆを天井板１６に押し当てた状態で天井に埋め込み設置されるようになっている。
【００２５】
図３（Ａ）中符号１７は電線の引込み孔を示している。同様に、図３（Ａ）中符号１８は奥壁２ｂの内面に取付けられた端子台、符号１９は奥壁２ｂの内面に取付けられた電子安定器等の点灯装置を夫々示している。また、図４等に示すように、奥壁２ｂの内面には板金製の反射板２０が取付けられている。この反射板２０は器具本体２の長手方向に延びており、前記取付け孔１２、引込み孔１７、端子台１８、及び点灯装置１９を開口部２ｄ側から覆っている。
【００２６】
図２及び図４に示すように、奥壁２ｂの内面には、器具本体２の幅方向に延びる一対のソケット取付け台２１が器具本体２の長手方向両端部に位置して取付けられている。これらのソケット取付け台２１には反射板２０を間に置いて片側２個計４個のランプソケット２２が取付けられている。これら器具本体２の長手方向に対向するランプソケット２２には、これらに渡ってランプ２３が着脱可能に支持されている。
【００２７】
図２及び図３（Ａ）に示すように、開口部２ｄの縁部の長手方向両端部、すなわち側壁２ａの下縁部の長手方向両端部には、第１の引掛け孔２４が設けられている。また、開口部２ｄと対向する奥壁２ｂの長手方向両端部には、例えば器具本体２に収容されたランプ２３の背後に対向して第２の引掛け孔２５が反射板２０で被われることが無いように設けられている。これら第１及び第２の引掛け孔２４，２５は、後述する制光体ホルダ４を取付けるためのものであって、制光体ホルダ４の第１及び第２の引掛け部５２，５３が引掛けられるように形成されている。この照明器具１では、第１及び第２の引掛け孔２４，２５は、例えば器具本体２の長手方向に互いに平行となるように延びる横長なスリット状に形成されている。
【００２８】
また、この照明器具１では、第１及び第２の引掛け孔２４，２５は、例えばノックアウト孔として形成されている。すなわち、図２（Ａ）に示すように、第１の引掛け孔２４は、例えば第１の孔閉鎖部２６によって塞がれている。第１の孔閉鎖部２６は、第１の引掛け孔２４が有する一対の長辺の内２４ａ，２４ｂの奥壁２ｂ側（上側）の長辺２４ａ上に設けられた第１の繋ぎ部２８で器具本体２と繋がれている。この第１の孔閉鎖部２６は、第１の繋ぎ部２８を器具本体２から切り離して除去する、或いは、第１の繋ぎ部２８を支点として例えば器具本体２の外側に折り曲げることで、第１の引掛け孔２４を開口させることが可能となるように設けられている。
【００２９】
一方、第２の引掛け孔２５は、図２（Ｂ）に片側だけ示すように、例えば第２の孔閉鎖部２７によって塞がれている。第２の孔閉鎖部２７は、第２の引掛け孔２５が有する一対の長辺２５ａ，２５ｂのうちの器具本体２の幅方向外側の長辺２５ａ上に設けられた第２の繋ぎ部２９で器具本体２と繋がれている。この第２の孔閉鎖部２７は、第２の繋ぎ部２９を器具本体２から切り離して除去する、或いは、第２の繋ぎ部２９を支点として器具本体２の内側または外側に折り曲げることで、第２の引掛け孔２５を開口させることが可能となるように設けられている。
【００３０】
外枠式制光体３ａは、四角枠状をなす例えば木製の枠体３１と、この枠体３１の内側に取付けられた制光要素としての拡散透過性を有する制光板３２と、器具本体２の長手方向に沿って延びる枠体３１の平行な一対の枠部に複数例えば２つずつ計４つ取付けられたＶ字状のばね３３とを備えている。制光要素としては、光拡散透過板、または、格子状その他の形状のバッフル等を用いることができる。この外枠式制光体３ａでは、制光板３２としては例えば乳白色のアクリル樹脂が用いられている。
【００３１】
枠体３１は、器具本体２の開口部側縁部２ｅ，２ｆが作る枠形体よりも大きく形成されている。この枠体３１の背面（本実施形態では上面）には、開口部側縁部２ｅ，２ｆが嵌り込む環状の溝３１ｄが形成されているとともに、裏側方向に突出して遮光壁を兼ねる四角枠状の壁部３１ｂが一体に設けられている。この壁部３１ｂの内の互いに平行な一対の壁の根元には、ばね３３に対応してばね引掛け孔３１ｃが開けられている。そして、このばね引掛け孔３１ｃには金属製のばねベース３４の一辺が挿通されている。このばねベース３４の一辺はねじ３５により枠体３１に固定されている。なお、ばねベース３４の一辺及びねじ３５は、溝３１ｄへの開口部側縁部２ｅ，２ｆの収納を妨げないように溝３１ｄの底面３１ａより下がった位置に設けられている。ばねベース３４の他辺は、壁部３１ｂの内面に沿って設けられていて、この略円形状に曲成された先端部にばね３３の中央リング状部が支持されている。
【００３２】
制光体ホルダ４は、本体部５１、第１の引掛け部５２、第２の引掛け部５３、及びばね受け部５５を備えており、図５に示すように、例えば一体に形成されている。
【００３３】
本体部５１は、図５において上下方向に延びる本体主部５１ａ及びこの本体主部５１ａの下端から図５において左右方向に張出す一対の張出部５１ｂを備えて略Ｔ字状に形成されている。
【００３４】
第２の引掛け部５３は、本体主部５１ａの上端縁を本体主部５１ａとの角度が鋭角となるように折り曲げることで、本体部５１の上端に突設されている。第２の引掛け部５３の左右方向の長さは本体主部５１ａの左右方向の長さと比べて短くなるように設定されている。また、第２の引掛け孔５３の長手方向の長さは、第２の引掛け部５３の左右方向の長さよりも長く、且つ、本体主部５１ａの左右方向の長さよりも短くなるように設定されている。
【００３５】
ばね受け部５５は、一対の張出部５１ｂの上縁を張出部５１ｂと略直交するように前記第２の引掛け部５３とは異なる面側に折り曲げて形成されている。これらばね受け部５５には、ばね３３の中央リング状部から一体に延びた拡開部が着脱可能に引掛けられる奥広の係止溝５５ａが夫々形成されている。
【００３６】
また、本体主部５１ａの下端縁の中央部からは、この制光体ホルダ４を器具本体２に取付けたときに器具本体２の側壁２ａに沿うように傾斜しながら突出する突出部５４が突設されている。この制光体ホルダ４では、本体主部５１ａと突出部５４とのなす角度は鈍角となっている。
【００３７】
第１の引掛け部５２は、この突出部５４の下端縁を断面略Ｌ字状に折り曲げることで、突出部５４の下端に突設されている。詳しくは、第１の引掛け部５２は、突出部５４の下端縁を突出部５４と略直交するように前記第２の引掛け部５３と同じ面側に折り曲げるとともに、続けて突出部５４と略平行となるように下側に折り曲げることで略Ｌ字状に形成されている。第１の引掛け部５２の左右方向の長さは、本体主部５１ａの左右方向の長さと略同じ長さに設定されているとともに、第１の引掛け孔２２の長手方向の長さと比べて短くなるように設定されている。
【００３８】
前記構成の制光体ホルダ４は、以下の手順で器具本体２の内面に装着される。まず、第１の引掛け孔２４が第１の孔閉鎖部２６によって塞がれている場合、第１の孔閉鎖部２６に打撃を加えることで第１の繋ぎ部２８を器具本体２から切り離して第１の孔閉鎖部２６を除去する、或いは、第１の繋ぎ部２８を支点として第１の孔閉鎖部２６を器具本体２の外側に折り曲げることで、第１の引掛け孔２４を開口させる。
【００３９】
同様に、第２の引掛け孔２５が第２の孔閉鎖部２７によって塞がれている場合、第２の孔閉鎖部２７に打撃を加えることで第２の繋ぎ部２９を器具本体２から切り離して第２の孔閉鎖部２７を除去する、或いは第２の繋ぎ部２９を支点として第２の孔閉鎖部２７を器具本体２の内側又は外側に折り曲げることで、第２の引掛け孔２５を開口させる。
【００４０】
なお、孔閉鎖部を折り曲げる場合は、折り曲げた後の孔閉鎖部が制光体ホルダ４に干渉しないように側壁２ａまたは奥壁２ｂに対して鋭角に折り曲げるようにするのが好ましい。
【００４１】
制光体ホルダ４の一端部に設けられた第１の引掛け部５２を器具本体２の内側から器具本体２の外側に向けて斜め下方に移動させながら第１の引掛け孔２４に挿通させることで、第１の引掛け部５２を側壁２ａに引掛ける。第１の引掛け部５２が第１の引掛け孔２４が有する一対の長辺２４ａ，２４ｂのうちの下側の長辺２４ｂの縁に当接するまで制光体ホルダ４を引き下げる。続けて、第１の引掛け部５２を前記長辺２４ｂの縁を支点として回動させて、第２の引掛け孔２５と制光体ホルダ４の他端部に設けられた第２の引掛け部５３との位置を近づける。制光体ホルダ４を斜め上方に押上げるようにしながら、第２の引掛け部５３を第２の引掛け孔２５に器具本体２の内側から器具本体２の外側に向けて挿通させることで、第２の引掛け部５３を奥壁２ｂに引掛ける。
【００４２】
以上の手順により、図１に示すように、制光体ホルダ４は、第１及び第２の引掛け部５２，５３を器具本体２の外側に向けて突設させるとともにばね受け部５５を器具本体２の内側に突設させた状態で器具本体２に取付けられる。同様にして、４ヶ所に制光体ホルダ４が取付けられた器具本体２には、外枠式制光体３ａがこれら制光体ホルダ４を介して取付けられる。
【００４３】
つまり、図４において中心線よりも左側に示すように、外枠式制光体３ａの各Ｖ字状のばね３３が、制光体ホルダ４から離れた状態で、各ばね３３の一対の拡開部を互いに近寄るように指で窄めて対応する制光体ホルダ４の係止溝５５ａの内面に導入する。その後、指を離すことにより拡開部の中間部を係止溝５５ａの長手方向両縁部に夫々係合させる。この状態でばね３３は弾性変形している。次に、制光体ホルダ４の器具本体２の開口部２ｄに寄るように上向きに移動させる。
【００４４】
それにより、ばね３３の一対の拡開部が次第に開きながら外枠式制光体３ａが器具本体２にその開口部２ｄを被って取付けられる。この取付け状態では、図１に示すように、外枠式制光体３ａの枠体３１は開口部２ｄから外側に張出すように配置される。また、前記取付け状態でのばね３３と制光体ホルダ４との関係等は、図４において中心線よりも右側で示される。
【００４５】
また、この照明器具１が備える器具本体２は、図６及び図７に示すように、器具本体２にその開口部２ｄを塞ぐように配置される内枠式制光体３ｂを取付けることもできる。
【００４６】
内枠式制光体３ｂは、四角枠状に形成された枠体４２と、この枠体４２の内側に取付けられた拡散透光性を有する制光板４３とを備えている。枠体４２には、器具本体２の長手方向に沿って延びる枠体４２の一対の枠部のうちの一方の枠部に一対の第１の係合片４４が突設されているとともに、他方の枠部に一対の第２の係合片４５が取付けられている。第２の係合片４５はねじ回しを用いて回動操作されるものである。この第２の係合片４５は、図示しないが、枠体４２の内側内に配置される格納位置と、枠部に対して直角となって枠体４２の外側に突出する使用位置とにわたって回動される。
【００４７】
この内枠式制光体３ｂは、外枠式制光体３ａに代えて開口部２ｄに被着させるものであって、以下の手順で天井部にすでに設置された器具本体２に取付けられる。
【００４８】
まず、第１の引掛け孔２４が第１の孔閉鎖部２６によって塞がれている場合、上述したように、第１の孔閉鎖部２６に打撃を加えることで第１の繋ぎ部２８を器具本体２から切り離して第１の孔閉鎖部２６を除去する、或いは、第１の繋ぎ部２８を支点として第１の孔閉鎖部２６を器具本体２の外側に折り曲げることで、第１の引掛け孔２４を開口させる。
【００４９】
一対の第１の係合片４４の夫々を、器具本体２の一方の側壁２ａに形成された第１の引掛け孔２４に夫々挿通させて引掛ける。次に、この引掛かり部を支点として内枠式制光体３ｂを押上げて器具本体２の開口部２ｄ内に収め、第２の係合片４５を他方の側壁２ａに形成された第１の引掛け孔２４との位置合わせをする。この状態で、ねじ回しを用いて第２の係合片４５を格納位置から使用位置に回動させて、これら第２の係合片４５を他方の側壁２ａに形成された一対の引掛け孔に挿通させて係合させる。なお、他方の側壁２ａに形成された一対の第１の引掛け孔２４の下側に落とし込み部を形成しておき、第２の係合片４５をこの落とし込む部に自重を利用して落とし込んで取付けるようにしてもよい。
【００５０】
以上の手順によって、図７に示すように、内枠式制光体３ｂは開口部２ｄの内側に収容された状態でその幅方向両側を器具本体２の開口部側縁部２ｅに引掛け支持されて、開口部２ｄに被着される。なお、この内枠式制光体３ｂを器具本体２から取外すには、内枠式制光体３ｂを多少押上げて既述の取付け手順とは逆の手順で実施できる。
【００５１】
以上のように、前記構成の照明器具１では、第１の引掛け部５２を器具本体２の内側から外側に向けて第１の引掛け孔２４に挿通させることで第１の引掛け部５２を器具本体２の側壁２ａに引掛けることができるとともに、第２の引掛け部５３を器具本体２の内側から外側に向けて第２の引掛け孔２５に挿通させることで第２の引掛け部５３を器具本体２の奥壁２ｂに引掛けることができ、これにより、制光体ホルダ４を器具本体２に取付けることができる。すなわち、制光体ホルダ４を器具本体２に取付けるために溶接止めやねじ止めを伴わないため、制光体ホルダ４を器具本体２に容易に取付けることができる。
【００５２】
また、前記構成の照明器具１によれば、図１〜図４に示すように、外枠式制光体３ａを取付けた照明器具１として構成できるにもかかわらず、Ｖ字状のばね３３を有した外枠式制光体３ａ及び制光体ホルダ４を取外すことで、図６及び図７に示すように、内枠式制光体３ｂを取付けた照明器具１として構成することもできる。
【００５３】
さらに、この照明器具１によれば、第１及び第２の引掛け孔２４，２５が、第１及び第２の孔閉鎖部２７に打撃を加えることで第１及び第２の繋ぎ部２９を器具本体２から切り離して第１及び第２の孔閉鎖部２７を除去する、或いは、第１及び第２の繋ぎ部２９を支点として第１及び第２の孔閉鎖部２７を折り曲げることで、第１及び第２の引掛け孔２４，２５を開口させることが可能な第１及び第２孔閉鎖部によって塞がれている。
【００５４】
このように、第１及び第２の引掛け孔２４，２５を孔閉鎖部で塞いでおくことは、第１及び第２の引掛け孔２４，２５を使用しないで照明器具１を構成する場合（下面を開口して使用する場合等）や、第２の引掛け孔２５を使用しないで照明器具１を構成する場合（制光体として内枠式制光体３ｂを用いて照明器具１を構成する場合等）において、ランプ２３や制光体を除去して器具本体２内を覗いたときに第１及び第２の引掛け孔２４，２５が開口していないので体裁がよい点で優れている。
【００５５】
また、第１及び第２の繋ぎ部２９を器具本体２から切り離して第１及び第２の孔閉鎖部２７を除去する場合、繋ぎ部を器具本体２から切り離す際にかえりやまくれといった、いわゆるばりが残る。
【００５６】
第１の引掛け孔２４が有する一対の長辺２４ａ，２４ｂの内の下側の長辺２４ｂの縁にばりが残ると、第１の引掛け孔２４に第１の引掛け部５２を挿通させて側壁２ａに引掛ける際に第１の引掛け部５２の先端がばりに引掛かってその挿通が妨げられたり、或いは、制光体ホルダ４がばりで保持される等して正規の取付け位置ではない位置に取付けられてしまうおそれがある。
【００５７】
同様に、第２の引掛け孔２５が有する長辺２５ａ，２５ｂの内の器具本体２の幅方向中央側側の長辺２５ｂの縁にばりが残ると、第２の引掛け孔２５に第２の引掛け部５３を挿通させて奥壁２ｂに引掛ける際に第２の引掛け部５３の先端がばりに引掛かってその挿通が妨げられたり、或いは、制光体ホルダ４がばりで保持される等して正規の取付け位置ではない位置に取付けられてしまうおそれがある。
【００５８】
そして、万一、制光体ホルダ４が正確に器具本体２に取付けられていないと、制光体ホルダ４が器具本体２から外れて、制光体３ａが落下するおそれがある。
【００５９】
この照明器具１によれば、第１の孔閉鎖部２６は前記長辺２４ａ上に設けられた第１の繋ぎ部２８で器具本体２と繋がれており、第２の孔閉鎖部２７は前記長辺２５ａ上に設けられた第２の繋ぎ部２９で器具本体２と繋がれているため、第１及び第２の引掛け孔２４，２５の長辺２４ｂ、２５ｂの縁にはばりが残らない。したがって、第１及び第２の引掛け部５２，５３を第１及び第２の引掛け孔２４，２５に良好に挿通させることができるとともに、制光体ホルダ４が正規の取付け位置ではない位置で器具本体２に取付けられることを抑制することができる。
【００６０】
