【発明の属する技術分野】
この発明は、例えば換気や空調等においてエア送風に用いる送風用筒体を取付板に固定するための送風用筒体固定装置に関するものである。
【０００２】
【従来の技術】
従来、この種の送風用筒体固定装置としては、例えば図２７〜図２９に示したような機器の取付装置が知られている（例えば、特許文献１参照）。
【０００３】
この機器の取付装置では、天井となる取付面１に取付孔２が形成され、筒状の本体枠３が取付孔２に挿通されている。この本体枠３の下端部には取付面１のに当接するフランジ３ａが形成され、本体枠３の上端部には小径のダクト接続部３ｂが形成されている。そして、このダクト接続部３ｂの外周に上部の空間に配設される送風用のダクト（図示せず）が嵌着されるようになっている。
【０００４】
また、本体枠３の左右の側面には上下に延びる突部４が設けられている。この突部４内には上下に延び且つ側方に開放する凹状の溝部４ａが形成されている。また、突部４の基部には、互いに対向して上下に延び且つ溝部４ａに開口する凹部４ｂ，４ｂが形成されている。これにより、突部４は平面形状が略Ｔ字状に形成されている。
【０００５】
そして、溝部４ａには複数箇所で屈曲させられた取付金具５の基部が配設されている。この取付金具５の基部の側面には突起部５ａ，５ａが設けられ、取付金具５の基部及び中間部にはこれらに跨って長手方向に延びる長孔５ｂが形成されている。しかも、凹部４ｂ，４ｂには取付金具５の基部の突起部５ａ，５ａが上下動可能に係合させられている。
【０００６】
また、溝部４ａ内には方形状の可動体６が取付金具５より上方に位置させて上下動可能に配設され、この可動体６には溝部４ａの底壁４ｃ及び長孔５ｂを貫通するボルト７が螺着されている。尚、取付金具５は、突起部５ａ，５ａを中心に回動して、二点鎖線で示した起立位置（収納位置）と実線で示した倒伏位置（使用位置）との間で回動できるようになっている。８は取付金具５の先端部に回動可能に装着された方形状の押さえ金具である。
【０００７】
このような構成において、突部４を取付面１の取付孔２に固定するには、先ず取付金具５を二点鎖線で示したように起立させて溝部４ａ内に配設した状態で、本体枠３を取付孔２に取付面１の下方から挿入し、本体枠３のフランジ３ａを取付面１の下面に当接させる。次に、取付金具５を実線で示したように倒して、押さえ金具８を取付面１の上面に当接させる。この後、ボルト７を回転操作して可動体６を降下させて、可動体６で取付金具５の中間部を下方に押さえ付けることにより、押さえ金具８とフランジ５ｂとの間で取付面１を挟持させると、本体枠３が取付面１に固定されることになる。

【発明が解決しようとする課題】
ところで、このような取付構造では、取付金具５を起立させて取付金具５の先端部を溝部４ａ内に収容したときに、取付金具５の起立状態を維持させることが難しいものであった。
【００１０】
また、上述の取付構造では、押さえ金具８を取付金具５の先端部に回動可能に取り付けていたため、取付金具５を起立させて取付金具５の先端部をガイド溝４ａ内に収容しても、本体枠３を取付孔２に挿入する際に、押さえ金具８が自重や振動で回動してガイド溝４ａから一部突出する虞があった。このため、本体枠３を取付孔２に挿入する際に、押さえ金具８が取付面１に引っかからないようにするために、取付孔２の内径を大きく取る必要があった。しかしながら、取付孔２の内径を大きくとっても、筒体３を取付孔２に挿入する際に、押さえ金具（可動押さえ板）８が取付面１に引っかかる虞があった。
【００１１】
そこで、この発明は、可動押え部材を送風用筒体から取り外しておくことで、送風用筒体を取付孔に挿入する際に、可動押え部材をガイド溝内に収容したりする必要がなく、可動押え部材が取付部材に引っかかったりすることがない送風用筒体固定装置を提供することを目的とするものである。
【００１２】
【課題を解決するための手段】
この目的を達成するため、請求項１の発明は、取付部材の互いに反対側に位置する第１，第２壁面に開口させた筒体取付孔が前記取付部材に設けられ、前記第１壁面に対して進退動可能に送風用筒体に設けられた可動押え部材と前記送風用筒体に設けられた固定支持部とで前記取付部材を挟持固定可能な送風用筒体固定装置であって、前記送風用筒体に第１壁面側に開口したスリットが形成され、前記送風用筒体内に筒状の環状体が嵌合され、前記環状体には前記中心線に沿う方向の複数箇所に前記可動押え部材の取付孔であるスリットが形成されていると共に、前記可動押え部材は前記環状体とは別体に形成され、前記可動押え部材が前記環状体の複数のスリットの何れか一つ及び前記送風用筒体のスリットを介して前記送風用筒体の外方に突出可能に設けられている送風用筒体固定装置としたことを特徴とする。
【００１５】
また、請求項２の発明は、請求項１に記載の送風用筒体固定装置において、円弧状板部と円弧状板部に一体に設けられた押さえ板部を有する可動押え部材が複数設けられ、前記複数の可動押え部材は円弧状板部の隣接する端部同士を互いに相対移動可能に結合することにより環状に且つ外形を縮小する方向に変形可能な環状部材に形成されていると共に、前記複数の可動押え部材は前記環状部材の外形が縮小する方向に変形させたときに前記送風用筒体内に配設可能に設けられ、且つ、前記複数の可動押え部材は前記環状部材を広げて前記送風用筒体の内周面に沿わせたときに前記スリットから突出させられて前記第１壁面に平行に対向するように設けられていることを特徴とする。
【００１６】
さらに、請求項３の発明は、請求項２に記載の送風用筒体固定装置において、前記押さえ板部は前記中心線に沿う方向に延びる脚部を介して前記円弧状板部に一体に形成されていることを特徴とする。
【００１７】
【発明の実施の形態１】
以下、この発明の実施の形態を図１〜図１８に基づいて説明する。
[構成]
図１において、１０は石膏ボードからなる天井板（取付板、取付部材）、１０ａは天井板１０の上面（第１壁面）、１０ｂは天井板１０の下面（第２壁面）である。この天井板１０には、上面１０ａ及び下面１０ｂに開口する筒体取付孔１１が形成されている。
【００１８】
また、１２は合成樹脂製で筒状のグリル本体（送風用筒体）である。このグリル本体１２は、上から順に連設された小径筒部１２ａ，中径筒部１２ｂ，大径筒部１２ｃを有する。このグリル本体１２は、筒体取付孔１１に下方から挿入することで、大半が上面１０ａ側に配設されると共に、一端部である大径筒部１２ｃが筒体取付孔１２内に嵌合されている。しかも、この大径筒部１２ｃの下端にはフランジ１２ｄが固定支持板部（固定支持部）として一体に形成されている。このフランジ１２ｄは天井板１０の下面１０ｂに当接させられている。
【００１９】
また、中径筒部１２ｂには互いに反対側に位置させて上下に延びるスリット１２ｅ，１２ｅが形成されている。１２ｆは小径筒部１２ａと中径筒部１２ｂとを連設している段壁である。尚、小径筒部１０ａの外周には、天井板１０の上方（天井裏）に配管された送風ダクト１３の端部が嵌着されている。このグリル本体１２の下端部には、図示を省略したルーバー等が装着される。
【００２０】
このグリル本体１２の中径筒部１２ｂ内には、図２〜図８に示した金属製の環状体（筒状体）１４がグリル本体１２の中心線に沿う方向に移動可能に可動体として嵌合されている。この環状体１４は、筒状部１４ａと、この筒状部１４ａの一端に内方に向けて連設されたフランジ１４ｂと、フランジ１４ｂの内周縁の互いに反対側の部分に設けられた折曲支持片１４ｃ，１４ｃを有する。
【００２１】
この折曲支持片１４ｃ，１４ｃは筒状部１４ａ内に位置していて、この折曲支持片１４ｃ，１４ｃには水平方向に延びる一つのスリット（係止孔）１５，１５がそれぞれ形成されている。また、筒状部１４ａには、スリット１５，１５の一方に対応する部分に位置させて、周方向に水平に延び且つ互いに平行に形成された一対のスリット（係止孔）１６，１７が形成されている。同様に筒状部１４ａには、スリット１５，１５の他方に対応する部分に位置させて、同様なスリット１６，１７が形成されている。
【００２２】
このスリット１５，１６，１７は、環状体１４の軸線（中心線）と平行な方向に等ピッチで配列されている。しかも、フランジ１４ｂには折曲支持片１４ｃ，１４ｃと筒状部１４ａとの間に開口するネジ孔１８，１８が形成されている。 １９，１９は金属製の可動押さえ板（押さえ金具、可動押え部材）である。この各可動押さえ板（可動押さえ金具）１９は、長さの長い押さえ板部１９ａと、長さの短い係止板部１９ｂと、押さえ板部１９ａ及び係止板部１９ｂを連設している連設板部１９ｃから側面形状がクランク状に形成されている。しかも、押さえ板部１９ａには連設板部１９ｃに隣接してネジ挿通孔１９ｄが形成されている。
【００２３】
そして、図１において可動押さえ板１９，１９の押さえ板部１９ａ，１９ａは、スリット１６，１２ｅ及び１６，１２ｅに挿通されていると共に、天井板１０の上面１０ａに当接させられている。また、可動押さえ板１９，１９の係止板部１９ｂ，１９ｂはスリット１５，１５に挿通させられ、可動押さえ板１９，１９の連設板部１９ｃ，１９ｃは折曲支持片１４ｃ，１４ｃに沿わせられている。また、ネジ挿通孔１９ｄ，１９ｄには締付固定ネジ（固定操作手段）２０，２０が挿通されている。しかも、この締付固定ネジ２０、２０は、環状体１４のネジ孔１８，１８に螺着されていると共に、グリル本体１２の段壁１２ｆに先端が当接させられている。これにより、可動押さえ板１９，１９の押さえ板部１９ａ，１９ａとグリル本体１２のフランジ１２ｄとの間で天井板１０を挟持している。
【００２４】
尚、このような環状体１４，一対の可動押さえ板１９，１９はグリル本体１２を天井板１０に固定するグリル固定金具（可動押え部材）ＧＭＢ１を構成している。また、このグリル固定金具と締付固定ネジ２０，２０は、グリル本体１２を天井板１０に固定するグリル固定装置（送風用筒体固定装置）を構成している。[作用]
次に、この様な構成のグリル本体１２の天井板１０への取付について説明する。
（１）天井板１０が薄い場合
先ず、グリル本体１２を小径筒部１２ａ側から天井板１０の取付孔１１に挿入して、小径筒部１２ａ及び中径筒部１２ｂを天井板１０の上面１０ａから上方に突出させると共に、大径筒部１２ｃを取付孔１１に嵌合して、フランジ１２ｄを天井板１０の下面１０ｂに当接させる。
【００２５】
この際、フランジ１４ｂを上側にして環状体１４をグリル本体１２の中径筒部１２ｂ内に下側から嵌合し、環状体１２のスリット１６，１７を中径筒部１２ｂのスリット１２ｅに合わせる。
【００２６】
そして、天井板１０が比較的に薄い場合（例えば天井板１０が９ｍｍ程度の場合）には、図１２に示したように、係止板部１２ｂを上側に位置させて、可動押さえ板１９の押さえ板部１９ａを下側のスリット１６及び１２ｅに下側から斜め上方に向けて挿通した後、係止板部１２ｂを折曲支持片１４ｃのスリット１５に挿通する。
【００２７】
次に、締付固定ネジ２０を可動押さえ板１９のネジ挿通孔１９ｄに挿通した後、この締付固定ネジ２０を環状体１２のネジ孔１８に螺着する。そして、更に締付固定ネジ２０を回転操作して、締付固定ネジ２０の先端をグリル本体１２の段壁１２ｆに当接させることにより、環状体１２に下方への押圧力を作用させる。この際、可動押さえ板１９の押さえ板部１９ａが天井板１０の上面１０ａに押し付けられて、可動押さえ板部１９ａとグリル本体１２のフランジ１２ｄとの間に締付保持力が作用し、グリル本体１２が天井板１０に取付孔１１の部分で固定されることになる（図１１，図１２参照）。
（２）天井板１０が厚い場合
また、天井板１０が比較的に厚い場合（例えば天井板１０が２５ｍｍ程度の場合）、図１４〜図１６に示したように、可動押さえ板１９を上述とは逆に反転させて即ち係止板部１２ｂを上側に位置させて、可動押さえ板１９の押さえ板部１９ａを上側のスリット１７及び１２ｅに下側から斜め上方に向けて挿通した後、係止板部１２ｂを折曲支持片１４ｃのスリット１５に挿通する（図２参照）。
【００２８】
この後、締付固定ネジ２０を可動押さえ板１９のネジ挿通孔１９ｄに挿通し、この締付固定ネジ２０を環状体１２のネジ孔１８に螺着する。そして、更に締付固定ネジ２０を回転操作して、締付固定ネジ２０の先端をグリル本体１２の段壁１２ｆに当接させることにより、環状体１２に下方への押圧力を作用させる。この際、可動押さえ板１９の押さえ板部１９ａが天井板１０の上面１０ａに押し付けられて、可動押さえ板部１９ａとグリル本体１２のフランジ１２ｄとの間に締付保持力が作用し、グリル本体１２が天井板１０に取付孔１１の部分で固定されることになる。
【００２９】
本実施例の場合には天井板１０が９ｍｍ〜２５ｍｍの範囲であれば、グリル本体１２を天井板１０に取り付けることができる。尚、この数値は一例を示したもので、この数値に限定されるものではない。例えば、環状体１４の軸線に沿う方向におけるスリット１５，１６，１７の間隔を変えることで、グリル本体１２の取り付けられる天井板の厚さの範囲を変えることができる。
【００３０】
【発明の実施の形態２】
[構成]
また、以上説明した実施例では、グリル固定金具を環状体１４と一対の可動押さえ板１９，１９から構成して、環状体１４をグリル本体１２の中径筒部１２ｂ内に嵌合した後、一対の可動押さえ板１９，１９を個別に環状体１４に装着するようにしたが、必ずしもこの構成に限定されるものではない。
【００３１】
例えば、図１８〜図２０に示したように環状体である環状板２１と一対の可動押さえ板２２，２２を一体的に取り扱うことができるように構成しても良い。
【００３２】
この環状板２１及び可動押さえ板２２，２２は、金属板から形成されていて、グリル本体１２を天井板１０に固定するグリル固定金具（可動押さえ部材）ＧＭＢ１を構成している。このグリル固定金具と上述した締付固定ネジ２０は、グリル固定装置（送風用筒体固定装置）を構成している。尚、グリル本体１２や締付固定ネジ２０は発明の実施の形態１と同一であるので、上述した部分と同じ部分には上述した符号と同じ符号を付して説明する。
【００３３】
この環状板（環状金属板）２１は、図２２に示したように、左右の円弧状板部２１ａ，２１ａと、円弧状板部２１ａ，２１ａを連設している直線板部２１ｂ，２１ｂを有する。この円弧状板部２１ａ，２１ａの曲率半径中心は一致させられている。しかも、円弧状板部２１ａ，２１ａの長手方向中央部には、内周に開放する切欠２１ｃ，２１ｃが形成されている。また、各円弧状板部２１ａには、切欠２１ｃから互いに反対側に位置させてネジ孔２１ｄ，２１ｄ及びネジ挿通孔２１ｆ，２１ｆがそれぞれ形成されている。更に、直線板部２１ｂ，２１ｂの長手方向の中央にはネジ孔２１ｅ，２１ｅが形成されている。
【００３４】
また、一対の可動押さえ板（可動押さえ金具）２２，２２は、円弧状板部２２ａと、円弧状板部２２ａの一端部に設けられた段差部２２ｂと、円弧状板部２２ａの一端部に連設された直線板部２２ｃと、円弧状板部２２ａの他端部に連設された直線板部２２ｄを有する。しかも、可動押さえ板２２は、長手方向中央部の外周縁に一体に設けられた起立板部（脚部）２２ｅと、円弧状板部２２ａの半径方向（外方）に向けて起立板部２２ｅに連設された押さえ板部２２ｆを有する。
【００３５】
更に、円弧状板部２２ａには、長手方向中央に位置してネジ孔２２ｇが形成されていると共に、ネジ孔２１ｄ，２１ｄに対応してネジ挿通孔２２ｈ，２２ｈが形成され、ネジ挿通孔２１ｆ，２１ｆに対応してネジ孔２２ｊ，２２ｊが形成されている。また、直線板部２２ｃ，２２ｄにはスリット２２ｃ１，２２ｄ１がそれぞれ形成されている。
【００３６】
この可動押さえ板２２，２２は、一方の可動押さえ板２２に設けた直線板部２２ｃと他方の可動押さえ板２２に設けた直線板部２２ｄとが、円弧状板部２２ａ，２２ａの両端において互いに重ね合わせられている。これにより、可動押さえ板２２，２２は、円弧状板部２２ａ，２２ａ同士が一端部を除いて面一になるようになっている。しかも、一対の可動押さえ板２２，２２の円弧状板部２２ａ，２２ａの両端部は、保持ネジ２３，２３により環状板２１の直線板部２１ｂ，２１ｂの部分に、円弧状板部２２ａ，２２ａ同士が接近・離反変位可能に保持されている。即ち、図１８（ｂ）の如く各保持ネジ２３の基部２３ａを重ね合わせられた直線板部２２ｃ，２２ｄのスリット２２ｃ１，２２ｄ１に挿通すると共に、この保持ネジ２３の先端ネジ部２３ｂを環状板２１のネジ孔２１ｅに螺着することで、円弧状板部２２ａ，２２ａ同士が接近・離反変位可能に保持されている。
【００３７】
これにより、可動押さえ板２２，２２は外形を大きく又は小さくできる環状部材を形成している。
【００３８】
また、複数のネジ挿通孔２２にそれぞれ挿通した固定ネジ２４を環状板２１の複数のネジ孔２１ｄにそれぞれ螺着することで、可動押さえ板２２，２２は環状板２１に固定されている。しかも、締付固定ネジ２０は、可動押さえ板２２のネジ孔２２ｇに図１８（ｃ）の如く螺着されていると共に、環状板２１の切欠２１ｃに挿通され、先端がグリル本体１２の段差壁１２ｆに当接させられている。この状態で、締付固定ネジ２０を締め付けることにより、押さえ板部２２ｆ，２２ｆが天井板１０の上面に押し付けられて、この押さえ板部２２ｆ，２２ｆとグリル本体１２のフランジ１２ｄとにより天井板１０を挟持している。
[作用]
次に、この様な構成のグリル固定装置（送風用筒体固定装置）によりグリル本体１２を天井板１０へ取り付ける手順を説明する。
（１）天井板１０が薄い場合
先ず、グリル本体１２を小径筒部１２ａ側から天井板１０の取付孔１１に挿入して、小径筒部１２ａ及び中径筒部１２ｂを天井板１０の上面１０ａから上方に突出させると共に、大径筒部１２ｃを取付孔１１に嵌合して、フランジ１２ｄを天井板１０の下面１０ｂに当接させる。
【００３９】
一方、図２０，図２１に示したように、可動押さえ板２２，２２を互いに接近する方向に押圧することにより、円弧状板部２１ａ，２１ａの両端に設けた直線板部２２ｃ，２２ｄがスリット２２ｃ１，２２ｄ１と保持ピン２３によりガイドされて相対的に変位させられ、可動押さえ板２２，２２が相対的に接近させられる。このようにして、可動押さえ板２２，２２の押さえ板部２２ｆ，２２ｆの先端が環状板２１の円弧状板部２１ａ，２１ａの外周縁から突出しないようにしておく。
【００４０】
そして、天井板１０が比較的に薄い場合（例えば天井板１０が９ｍｍ程度の場合）には、図１８に示したように、環状板２１を上方にしてグリル固定金具ＧＭＢ２をグリル本体１２の中径筒部１２ｂ内に下方から挿入すると共に、可動押さえ板２２，２２の押さえ板部２２ｆ，２２ｆをグリル本体１２のスリット１２ｅ，１２ｅに合わせる。
【００４１】
この後、可動押さえ板２２，２２を上述とは逆に互いに離反する方向に押圧して、可動押さえ板２２，２２の押さえ板部２２ｆ，２２ｆをグリル本体１２のスリット１２ｅ，１２ｅから中径筒部１２ｂの外方に突出させると共に、押さえ板部２２ｆ，２２ｆを天井板１０の上面に当接させる。この際、円弧状板部２２ａ，２２ａ円弧状板部２２ａ，２２ａ外周縁を環状板２１の外周縁に一致させることにより、複数のネジ挿通孔２２ｈを環状板２１の複数のネジ孔２１ｄそれぞれに合わせると共に、ネジ孔２２ｇを環状板２１の切欠２１ｃに合わせる。
【００４２】
この状態で、複数のネジ挿通孔２２にそれぞれ挿通した固定ネジ２４を環状板２１の複数のネジ孔２１ｄにそれぞれ螺着することで、可動押さえ板２２，２２を環状板２１に固定させる。この後、締付固定ネジ２０を、可動押さえ板２２のネジ孔２２ｇに図１８（ｃ）の如く螺着すると共に、環状板２１の切欠２１ｃに挿通する。そして、締付固定ネジ２０の先端をグリル本体１２の段差壁１２ｆに当接させて、更に締付固定ネジ２０を回転操作して締め付けることにより、押さえ板部２２ｆ，２２ｆが天井板１０の上面に押し付け、この押さえ板部２２ｆ，２２ｆとグリル本体１２のフランジ１２ｄとで天井板１０を挟持させる。これにより、グリル本体１２が天井板１０に固定されることになる。
（２）天井板１０が厚い場合
上述と同様に、グリル本体１２を小径筒部１２ａ側から天井板１０の取付孔１１に挿入して、小径筒部１２ａ及び中径筒部１２ｂを天井板１０の上面１０ａから上方に突出させると共に、大径筒部１２ｃを取付孔１１に嵌合して、フランジ１２ｄを天井板１０の下面１０ｂに当接させる。
【００４３】
一方、図２０，図２１に示したように、可動押さえ板２２，２２を互いに接近する方向に押圧することにより、円弧状板部２１ａ，２１ａの両端に設けた直線板部２２ｃ，２２ｄがスリット２２ｃ１，２２ｄ１と保持ピン２３によりガイドされて相対的に変位させられ、可動押さえ板２２，２２が相対的に接近させられる。このようにして、可動押さえ板２２，２２の押さえ板部２２ｆ，２２ｆの先端が環状板２１の円弧状板部２１ａ，２１ａの外周縁から突出しないようにしておく。
【００４４】
そして、天井板１０が比較的に厚い場合（例えば天井板１０が２５ｍｍ程度の場合）、図２６に示したように、環状板２１を上述とは逆に反転させて下側に位置させて、グリル固定金具ＧＭＢ２をグリル本体１２の中径筒部１２ｂ内に下方から挿入すると共に、可動押さえ板２２，２２の押さえ板部２２ｆ，２２ｆをグリル本体１２のスリット１２ｅ，１２ｅに合わせる。
【００４５】
この後、可動押さえ板２２，２２を上述とは逆に互いに離反する方向に押圧して、可動押さえ板２２，２２の押さえ板部２２ｆ，２２ｆをグリル本体１２のスリット１２ｅ，１２ｅから中径筒部１２ｂの外方に突出させると共に、押さえ板部２２ｆ，２２ｆを天井板１０の上面に当接させる。この際、円弧状板部２２ａ，２２ａ円弧状板部２２ａ，２２ａ外周縁を環状板２１の外周縁に一致させることにより、環状板２１の複数のネジ挿通孔２１ｆを可動押さえ板２２，２２の複数のネジ孔２２ｊそれぞれに合わせると共に、環状板２１の切欠２１ｃを可動押さえ板２２，２２のネジ孔２２ｇ，２２ｇに合わせる。
【００４６】
この状態で、複数のネジ挿通孔２１ｆにそれぞれ挿通した固定ネジ２４を可動押さえ板２２の複数のネジ孔２２ｊにそれぞれ螺着することで、可動押さえ板２２，２２を環状板２１に固定させる。
【００４７】
この後、締付固定ネジ２０を、環状板２１の切欠２１ｃに挿通すると共に、可動押さえ板２２のネジ孔２２ｇに図１８（ｃ）の如く螺着する。そして、締付固定ネジ２０の先端をグリル本体１２の段差壁１２ｆに当接させて、更に締付固定ネジ２０を回転操作して締め付けることにより、押さえ板部２２ｆ，２２ｆが天井板１０の上面に押し付け、この押さえ板部２２ｆ，２２ｆとグリル本体１２のフランジ１２ｄとで天井板１０を挟持させる。これにより、グリル本体１２が天井板１０に固定されることになる。
【００４８】
以上説明したようにこの発明の実施の形態の送風用筒体固定装置では、取付部材（天井板１０）の互いに反対側に位置する第１壁面（上面１０ａ），第２壁面（下面１０ｂ）に開口させた筒体取付孔１１が前記取付部材（天井板１０）に設けられている。しかも、前記第１壁面（上面１０ａ）に対して進退動可能に送風用筒体に設けられた可動押え部材[可動押さえ板１９（２２）]と前記送風用筒体（グリル本体１２）に設けられた固定支持部（フランジ１２ｄ）とで前記取付部材（天井板１０）を挟持固定可能な送風用筒体固定装置であって、前記送風用筒体（グリル本体１２）に第１壁面（上面１０ａ）側に開口したスリット１２ｅが形成され、前記可動押え部材[可動押さえ板１９（２２）]が前記スリット１２ｅを介して前記送風用筒体（グリル本体１２の外方に突出可能に設けられている。
【００４９】
この構成によれば、可動押え部材[可動押さえ板１９（２２）]を送風用筒体（グリル本体１２）から取り外しておくことで、送風用筒体（グリル本体１２）を取付孔１１に挿入する際に、可動押え部材[可動押さえ板１９（２２）]を従来の様にガイド溝内に収容したりする必要がなく、可動押え部材[可動押さえ板１９（２２）]が取付部材（天井板１０）に引っかかったりすることがない。
【００５０】
