Description

【０００１】
【発明の属する技術分野】
本発明は、移動体に軸調整部材を介して取り付けられ、軸調整部材を治具で操作することで軸調整可能な移動体搭載装置における軸調整装置に関する。
【０００２】
【従来の技術】
ＡＣＣシステム（アダプティブ・クルーズ・コントロール・システム）、Ｓｔｏｐ＆Ｇｏシステム（渋滞追従システム）、車間警報システム等に使用されるレーダー装置を車両に取り付ける場合、そのレーダー装置の対象物検知軸の方向が予め設定した目標とする対象物検知軸の方向を正しく指向していないと、隣車線の対向車を誤検知してシステムが誤作動したり、路面、陸橋、看板だけを検知して先行車を検知しないためにシステムが作動しないという問題が発生する。そこで、レーダー装置の対象物検知軸の方向を目標とする対象物検知軸の方向に一致させるエイミングを行う必要がある。
【０００３】
このようなレーダー装置の光軸調整を、ねじ機構を備えた光軸調整杆を回転させることで行うものが、特開平５−２７０３７号公報により公知である。
【０００４】
【発明が解決しようとする課題】
ところで、製造工場やサービス工場でレーダー装置のエイミングを完了した車両がユーザーに渡った後、ユーザーが対象物検知軸調整用のねじ機構を不用意に弄ると対象物検知軸が再びずれてしまう虞がある。これを防止するために、ねじ機構をカバーで覆って操作できなくすることが考えられるが、このようにすると、サービス工場でエイミングを行う場合に、カバーを取り外す余分な工数が発生してしまう問題がある。
【０００５】
本発明は前述の事情に鑑みてなされたもので、移動体搭載装置の軸調整部材の操作性を維持しながら、その軸調整部材が妄りに操作されるのを防止することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、請求項１に記載された発明によれば、移動体に取り付けられて軸調整部材を治具で操作することで軸調整可能な移動体搭載装置であって、軸調整部材に至るまでの治具挿入経路に位置していて、治具の挿入を許容する連通状態から、治具の挿入を阻止する遮蔽状態へ切換可能な切換機構を備えるものにおいて、切換機構は、これを治具の所定の挿入方法によって遮蔽状態から連通状態へ切換可能とするために、少なくとも治具の通過を阻止可能な遮蔽部と、治具が通過可能な開口を有する連通部とを備えていて、通常状態では遮蔽部が治具挿入経路に位置し、また前記所定の挿入方法がなされたときには、遮蔽部に代えて連通部を治具挿入経路に位置させることで、連通部の開口を通して治具を軸調整部材まで挿入可能としていることを特徴とする移動体搭載装置における軸調整装置が提案される。
【０００７】
上記構成によれば、遮蔽状態と連通状態との間を切換可能な切換機構を軸調整部材に至るまでの治具挿入経路に設け、治具を通常の挿入方法で挿入すると切換機構が遮蔽状態になって、軸調整部材が操作されるのを防止できる一方、治具を所定の挿入方法で挿入すると切換機構が連通状態になって軸調整部材を操作できるようにしたので、軸調整部材の操作性を維持しながら、その軸調整部材が妄りに操作されるのを防止することができる。また特に切換機構に少なくとも治具の挿入を阻止可能な遮蔽部と治具を挿入可能な開口を有する連通部とを設けたので、通常状態では遮蔽部を治具挿入経路に位置させ、治具を遮蔽部で阻止して軸調整部材まで挿入できないようにすることができ、また治具を所定の挿入方法で挿入することで遮蔽部に代えて連通部を治具挿入経路に位置させ、連通部の開口を通して治具を軸調整部材まで挿入することができる。
【０００８】
また請求項２に記載された発明によれば、請求項１の構成に加えて、切換機構は、断面Ｌ字状ないしＶ字状に屈曲した遮蔽部および連通部を有するシャッター部材と、シャッター部材の屈曲部あるいは端部を揺動自在に支持する支軸と、シャッター部材を囲むハウジングと、シャッター部材の連通部がハウジングの内壁に沿うように付勢する弾発部材とを備えたことを特徴とする移動体搭載装置における軸調整装置が提案される。
【０００９】

【００１０】
また請求項３に記載された発明によれば、請求項２の構成に加えて、前記所定の挿入方法は、連通部とハウジングの内壁との間に治具を挿入して弾発部材に抗して支軸まわりにシャッター部材を揺動させることで、連通部の開口を治具挿入経路に臨ませた状態で、治具を開口を通して軸調整部材まで挿入するものであることを特徴とする移動体搭載装置における軸調整装置が提案される。
【００１１】
上記構成によれば、治具を所定の挿入方法で挿入し、連通部とハウジングの内壁との間に治具を挿入して弾発部材に抗して支軸まわりにシャッター部材を揺動させると、連通部の開口が治具挿入経路に臨むため、治具を開口を通して軸調整部材まで挿入することができる。
【００１２】
また請求項４に記載された発明によれば、請求項２または請求項３の構成に加えて、シャッター部材の遮蔽部は、前記所定の挿入方法以外の方法で治具を挿入したときに、治具の挿入操作により支軸まわりに揺動してハウジングの内壁との協働で治具の挿入を阻止することを特徴とする移動体搭載装置における軸調整装置が提案される。
【００１３】
上記構成によれば、治具を所定の挿入方法以外の方法で挿入すると、シャッター部材の遮蔽部が支軸まわりに揺動してハウジングの内壁と協働して治具の挿入を阻止するので、治具が軸調整部材に達するのを確実に阻止することができる。
【００１４】
また請求項５に記載された発明によれば、移動体に取り付けられて軸調整部材を治具で操作することで軸調整可能な移動体搭載装置であって、軸調整部材に至るまでの治具挿入経路に位置していて、治具の挿入を許容する連通状態から、治具の挿入を阻止する遮蔽状態へ切換可能な切換機構を備えるものにおいて、切換機構は、これを治具の所定の挿入方法によって遮蔽状態から連通状態へ切換可能とするために、治具を挿入可能な開口を有して治具挿入経路を閉塞する隔壁と、隔壁の開口を開放する位置と閉塞する位置との間を移動するシャッター部材とを備え、前記所定の挿入方法は、治具によりシャッター部材を隔壁の開口を閉塞する位置から開放する位置へと移動させた状態で、治具を前記開口を通して軸調整部材まで挿入するものであることを特徴とする移動体搭載装置における軸調整装置が提案される。
【００１５】
上記構成によれば、遮蔽状態と連通状態との間を切換可能な切換機構を軸調整部材に至るまでの治具挿入経路に設け、治具を通常の挿入方法で挿入すると切換機構が遮蔽状態になって、軸調整部材が操作されるのを防止できる一方、治具を所定の挿入方法で挿入すると切換機構が連通状態になって軸調整部材を操作できるようにしたので、軸調整部材の操作性を維持しながら、その軸調整部材が妄りに操作されるのを防止することができる。また特に切換機構に、治具を挿入可能な開口を有して治具挿入経路を閉塞する隔壁と、隔壁の開口を開放する位置と閉塞する位置との間を移動するシャッター部材とを設けたので、通常状態では隔壁の開口をシャッター部材で覆って治具の挿入を阻止し、また治具を所定の挿入方法で挿入してシャッター部材を移動させることで、隔壁の開口を開いて治具の挿入を許容することができる。
【００１６】
また請求項６に記載された発明によれば、請求項５の構成に加えて、シャッター部材は隔壁の開口を開放する位置から閉塞する位置へと弾発部材で付勢されることを特徴とする移動体搭載装置における軸調整装置が提案される。
【００１７】
上記構成によれば、弾発部材がシャッター部材を隔壁の開口を開放する位置から閉塞する位置へと付勢するので、通常状態において隔壁の開口をシャッター部材で確実に覆うことができる。
【００１８】
また請求項７に記載された発明によれば、移動体に取り付けられて軸調整部材を治具で操作することで軸調整可能な移動体搭載装置であって、軸調整部材に至るまでの治具挿入経路に位置していて、治具の挿入を許容する連通状態から、治具の挿入を阻止する遮蔽状態へ切換可能な切換機構を備えるものにおいて、切換機構は、これを治具の所定の挿入方法によって遮蔽状態から連通状態へ切換可能とするために、支軸によって自己の軸線まわりに回転自在に支持されると共に前記軸線に直交するように貫通する開口が形成された円柱状のシャッター部材と、シャッター部材を囲むハウジングと、シャッター部材の開口がハウジングの内壁に対向するように付勢する弾発部材とを備え、前記所定の挿入方法は、治具により弾発部材に抗してシャッター部材を回転させ、シャッター部材の開口の方向を治具挿入経路に沿わせた状態で、治具を前記開口を通して軸調整部材まで挿入するものであることを特徴とする移動体搭載装置における軸調整装置が提案される。
【００１９】
上記構成によれば、遮蔽状態と連通状態との間を切換可能な切換機構を軸調整部材に至るまでの治具挿入経路に設け、治具を通常の挿入方法で挿入すると切換機構が遮蔽状態になって、軸調整部材が操作されるのを防止できる一方、治具を所定の挿入方法で挿入すると切換機構が連通状態になって軸調整部材を操作できるようにしたので、軸調整部材の操作性を維持しながら、その軸調整部材が妄りに操作されるのを防止することができる。また特に切換機構に、支軸により回転自在に支持された円柱状のシャッター部材と、シャッター部材を囲むハウジングと、シャッター部材を貫通する開口がハウジングの内壁に対向するように付勢する弾発部材とを設けたので、通常状態ではシャッター部材の開口をハウジングの内壁に対向させて治具の挿入を阻止し、また治具を所定の挿入方法で挿入してシャッター部材を弾発部材に抗して支軸まわりに回転させることで、シャッター部材の開口の方向を治具挿入経路に沿わせた状態で治具の挿入を許容することができる。
【００２０】

【００２１】
上記構成によれば、シャッター部材に係止部を設けたので、治具を係止部に係合させてシャッター部材を容易に回転させることができる。
【００２２】
また請求項９に記載された発明によれば、移動体に取り付けられて軸調整部材を治具で操作することで軸調整可能な移動体搭載装置であって、軸調整部材に至るまでの治具挿入経路に位置していて、治具の挿入を許容する連通状態から、治具の挿入を阻止する遮蔽状態へ切換可能な切換機構を備えるものにおいて、切換機構は、これを治具の所定の挿入方法によって遮蔽状態から連通状態へ切換可能とするために、治具挿入経路を囲むハウジングと、ハウジングの内部に支軸を介して一端側を支持され、治具挿入経路を開放する位置と閉塞する位置との間を揺動するシャッター部材とを備え、前記所定の挿入方法は、治具をシャッター部材の他端側に設けた係止部に係合させて、該シャッター部材を治具挿入経路を閉塞する位置から開放する位置へと揺動させた状態で、治具を軸調整部材まで挿入するものであることを特徴とする移動体搭載装置における軸調整装置が提案される。
【００２３】
上記構成によれば、遮蔽状態と連通状態との間を切換可能な切換機構を軸調整部材に至るまでの治具挿入経路に設け、治具を通常の挿入方法で挿入すると切換機構が遮蔽状態になって、軸調整部材が操作されるのを防止できる一方、治具を所定の挿入方法で挿入すると切換機構が連通状態になって軸調整部材を操作できるようにしたので、軸調整部材の操作性を維持しながら、その軸調整部材が妄りに操作されるのを防止することができる。また特に切換機構に、治具挿入経路を囲むハウジングと、ハウジングの内部に支軸を介して一端側を支持され、治具挿入経路を開放する位置と閉塞する位置との間を揺動するシャッター部材とを設けたので、通常状態では治具挿入経路をシャッター部材で閉塞して治具の挿入を阻止し、また治具を所定の挿入方法で挿入してシャッター部材を弾発部材に抗して支軸まわりに揺動させることで、治具挿入経路を開放して治具の挿入を許容することができる。
【００２４】
また請求項１０に記載された発明によれば、請求項１〜請求項９の何れか１項の構成に加えて、切換機構に対して軸調整部材の反対側に治具挿入孔を設け、前記所定の挿入方法で治具を挿入したとき、治具挿入孔、切換機構の開口および軸調整部材が直線上に位置することを特徴とする移動体搭載装置における軸調整装置が提案される。
【００２５】
上記構成によれば、治具挿入孔、切換機構の開口および軸調整部材が直線上に位置するので、治具を治具挿入孔から軸調整部材へと容易に導くことができる。
【００２６】
尚、実施例のレーダー装置Ｓｒは本発明の移動体搭載装置に対応し、実施例のボルト部材２０，２１は本発明の軸調整部材に対応し、実施例の捩じりばね３９，４２，４５は本発明の弾発部材に対応する。
【００２７】
【発明の実施の形態】
以下、本発明の実施の形態を、添付図面に示した本発明の実施例に基づいて説明する。図１〜図１３は本発明の第１実施例を示すもので、図１はレーダー装置を備えた車両の平面図、図２は図１の２方向矢視図、図３はレーダー装置の斜視図、図４は図３の４方向矢視図、図５は図３の５方向矢視図、図６は図３の６方向矢視図、図７は図５の７部拡大断面図、図８は図５の８部拡大断面図、図９は図４の９部拡大図、図１０は図９の１０−１０線断面図、図１１は図９の１１−１１線断面図、図１２は治具を不正に操作した場合の作用説明図、図１３は治具を適正に操作した場合の作用説明図である。
【００２８】
図１および図２に示すように、車両Ｖの進行方向に存在する前走車等の対象物を検知するレーダー装置Ｓｒは、フロントバンパー１の中央上部に固定されたフロントグリル２の後方であって、ボンネット３で開閉されるエンジンルーム４の前端部に配置される。尚、本明細書中で使用される前後左右の用語はシートに着座した乗員を基準とするもので、その定義は図３に示される。
【００２９】
図３〜図８から明らかなように、レーダー装置Ｓｒを支持板１２に支持するためのブラケット１３は、金属板をＬ字状断面に折り曲げた左右のブラケット本体１３ａ，１３ｂと、両ブラケット本体１３ａ，１３ｂの上端間および下端間を接続する上下の連結部材１３ｃ，１３ｄとで構成されており、その四隅が４本のボルト１４…で支持板１２に固定される。レーダー装置Ｓｒはレドーム３１およびケーシング３２を備えており、それらの内部に収納したレーダー機構部のフレーム１５から突出する３個のステー１５ａ，１５ｂ，１５ｃに合成樹脂製のナット部材１６，１７，１８が支持される。
【００３０】
各々のステー１５ａ，１５ｂ，１５ｃの後方に位置するように、左右のブラケット本体１３ａ，１３ｂに３個のボルト支持部材２２，２３，２４が固定される。図７に示すように、右上のステー１５ａの後方に位置するボルト支持部材２２を貫通するボルト部材１９の基端はプッシュナット２５により軸方向に固定され、雄ねじ部１９ａはナット部材１６に螺合する。
【００３１】
図８に示すように、右下および左上のステー１５ｂ，１５ｃの後方に位置するボルト支持部材２３，２４を貫通するボルト部材２０，２１に基端はプッシュナット２６，２７により軸方向に固定され、雄ねじ部２０ａ，２１ａはナット部材１７，１８に螺合する。ボルト部材２０，２１の頭部２０ｂ，２１ｂの前面にはギヤ歯２０ｃ，２１ｃが形成されており、このギヤ歯２０ｃ，２１ｃに対向するガイド突起２３ａ，２４ａがボルト支持部材２３，２４の後面に突出する。支持部材２３，２４の上面には、後述する治具２８を挿入するための開口２３ｂ，２４ｂが形成される。
【００３２】
図４に示すように、右上のボルト支持部材２２は右下のボルト支持部材２３に対して前方にずれており、従って上方から見たときに、右下のボルト支持部材２３の上面の開口２３ｂは右上のボルト支持部材２２に遮られることなく露出する。
【００３３】
右下のボルト支持部材２３に支持したボルト部材２０と、左上のボルト支持部材２４に支持したボルト部材２１とは、本発明の軸調整部材を構成する。治具２８によるボルト部材２０，２１の操作を許容する状態と阻止する状態とを切り換えるための切換機構３４Ｌ，３４Ｒが、左右のブラケット本体１３ａ，１３ｂにそれぞれ設けられる。左右の切換機構３４Ｌ，３４Ｒの構造は同一であり、その詳細は後から説明する。
【００３４】
右側の切換機構３４Ｒは、右下のボルト支持部材２３の開口２３ｂの上方に位置しており、かつレーダー装置Ｓｒを覆うグリルカバー３５に形成した治具挿入孔３５ａの下方に位置している。つまり、グリルカバー３５の治具挿入孔３５ａ、右側の切換機構３４Ｒおよび右下のボルト支持部材２３の開口２３ｂは治具挿入経路Ｐ（図１２および図１３参照）を構成する直線上に位置している。同様に、左側の切換機構３４Ｌは、左上のボルト支持部材２４の開口２４ｂの上方に位置しており、かつレーダー装置Ｓｒを覆うグリルカバー３５に形成した治具挿入孔３５ｂの下方に位置している。つまり、グリルカバー３５の治具挿入孔３５ｂ、左側の切換機構３４Ｌおよび左上のボルト支持部材２４の開口２４ｂは治具挿入経路Ｐ（図１３（Ｄ）参照）を構成する直線上に位置している。
【００３５】
次に、図９〜図１１に基づいて左右の切換機構３４Ｌ，３４Ｒの構造を説明する。左右の切換機構３４Ｌ，３４Ｒは実質的に同一の構造であるため、その代表として左側の切換機構３４Ｌの構造を説明する。
【００３６】
切換機構３４Ｌは上下面が開放した四角筒状のハウジング３６を備えており、その内部にＬ字状に屈曲したシャッター部材３７が支軸３８を介して揺動自在に支持される。シャッター部材３７は支軸３８から相互に直交する方向に延びる遮蔽部３７ａと連通部３７ｂとを備えており、連通部３７ｂの中央には治具２８を挿入可能な円形の開口３７ｃが形成されるとともに、連通部３７ｂの先端には治具２８が係合可能な係止部３７ｄが形成される。シャッター部材３７は支軸３８に支持した捩じりばね３９により、連通部３７ｂがハウジング３６の内壁３６ａに沿う位置に付勢されており、この状態で遮蔽部３７ａがハウジング３６の上下面間を遮っている。
【００３７】
次に、上記構成を備えた本発明の第１実施例の作用について説明する。
【００３８】
レーダー装置Ｓｒの対象物検知軸Ａｒの調整は以下のようにして行われる。即ち、レーダー装置Ｓｒの実際の対象物検知軸Ａｒが目標とする方向に対して上下方向にずれている場合には、治具２８の先端部２８ａを右下のボルト部材２０の頭部２０ｂのギヤ歯２０ｃに係合させて回転させる。このとき治具２８の先端部２８ａとボルト部材２０のギヤ歯２０ｃとの係合が外れないように、ボルト支持部材２３のガイド突起２３ａによって治具２８の先端部２８ａの背面が支持される（図８参照）。
【００３９】
右下のボルト部材２０を回転させてフレーム１５のステー１５ｂを前方に押し出すと、上側の２本のボルト部材１９，２１を支点としてレーダー装置Ｓｒが上向きに揺動し、対象物検知軸Ａｒが上向きに調整される。逆に、フレーム１５のステー１５ｂを後方に引き戻すと、上側の２本のボルト部材１９，２１を支点としてレーダー装置Ｓｒが下向きに揺動し、対象物検知軸Ａｒが下向きに調整される。
【００４０】
同様にして、治具２８を用いて左上のボルト部材２１を回転させてフレーム１５のステー１５ｃを前方に押し出すと、右側の２本のボルト部材１９，２０を支点としてレーダー装置Ｓｒが右向きに揺動し、対象物検知軸Ａｒが右向きに調整される。逆に、フレーム１５のステー１５ｃを後方に引き戻すと、右側の２本のボルト部材１９，２０を支点としてレーダー装置Ｓｒのが左向きに揺動し、対象物検知軸Ａｒが左向きに調整される。
【００４１】
以上のように、個々のレーダー装置Ｓｒの組立上の誤差により対象物検知軸Ａｒの方向がずれていても、その対象物検知軸Ａｒの方向を目標とする方向に正しく一致させることができる。
【００４２】
ところで、レーダー装置Ｓｒの軸調整が正しく行われていても、例えばユーザーが治具２８を用いてボルト部材２０，２１を操作してしまうと、せっかく調整した対象物検知軸Ａｒの方向がずれてしまう問題がある。このような不具合を解消すべく、治具２８の特別な操作方法を知らない者はボルト部材２０，２１を操作できないようになっている。
【００４３】
図１２に示すように、治具２８の特別な操作方法を知らない者が、ボルト部材２１を操作しようとグリルカバー３５の治具挿入孔３５ｂから、治具挿入経路Ｐに沿って治具２８を挿入すると、治具２８の先端部２８ａが切換機構３４Ｌのシャッター部材３７の遮蔽部３７ａに当接する（図１２（Ａ）参照）。治具２８を更に押し下げると、遮蔽部３７ａが下方に押圧されることでシャッター部材３７が捩じりばね３９に抗して支軸３８まわりに反時計方向に揺動し、連通部３７ｂの先端の係止部３７ｄが治具２８の側面を押すことになる（図１２（Ｂ）参照）。その結果、治具２８は治具挿入経路Ｐから側方にずれるため、その先端部２８ａがハウジング３６の内壁３６ａとシャッター部材３７の遮蔽部３７ａの先端との間に挟まれてしまい、ボルト支持部材２４の開口２４ｂに挿入することが不可能になる（図１２（Ｃ）参照）。
【００４４】
図１３に示すように、治具２８の特別な操作方法を知る者は、グリルカバー３５の治具挿入孔３５ｂから斜めに治具２８を挿入し、その先端部２８ａをシャッター部材３７の連通部３７ｂの先端の係止部３７ｄに当接させる（図１３（Ａ）参照）。続いて、治具２８を係止部３７ｄとハウジング３６の内壁３６ａとの間に挿入しながら、シャッター部材３７の連通部３７ｂを捩じりばね３９に抗して支軸３８まわりに反時計方向に揺動させる（図１３（Ｂ）参照）。その結果、治具２８の先端部２８ａはシャッター部材３７の連通部３７ｂの開口３７ｃに嵌合する（図１３（Ｃ）参照）。この状態から治具２８を治具挿入経路Ｐに沿って更に挿入すると、治具２８の先端部２８ａが遮蔽部３７ａを押し下げてシャッター部材３７が更に反時計方向に揺動するため、治具２８の先端部２８ａはボルト支持部材２４の開口２４ｂに挿入されてボルト部材２１のギヤ歯２１ｃに噛み合うことができる（図１３（Ｄ）参照）。
【００４５】
以上のように、治具２８の特別な操作方法を知るものだけがボルト部材２０，２１を操作することができるので、ボルト部材２０，２１が妄りに弄られてせっかく調整した対象物検知軸Ａｒの方向がずれてしまうのを防止することができる。またグリルカバー３５の治具挿入孔３５ａ，３５ｂ、切換機構３４Ｌ，３４Ｒの開口３７ｃ，３７ｃおよびボルト部材２０，２１が治具挿入経路Ｐに沿って直線上に配置されているので、治具２８を治具挿入孔３５ａ，３５ｂからボルト部材２０，２１へと容易に導くことができる。
【００４６】
図１４〜図１９は切換機構３４Ｌ，３４Ｒの第２実施例を示すもので、図１４は切換機構の平面図、図１５は図１４の１５−１５線断面図、図１６は図１４の１６−１６線断面図、図１７はシャッター部材の斜視図、図１８は治具を不正に操作した場合の作用説明図、図１９は治具を適正に操作した場合の作用説明図である。左右の切換機構３４Ｌ，３４Ｒは実質的に同一構造であるため、その代表として左側の切換機構３４Ｌの構造を説明する。
【００４７】
切換機構３４Ｌは上下面が開放した四角筒状のハウジング３６を備えており、その内部にシャッター部材３７が支軸３８を介して揺動自在に支持される。シャッター部材３７は遮蔽部３７ａと、連通部３７ｂと、補強部３７ｅとを備える。遮蔽部３７ａは開口を持たない板状部材であり、支軸３８の反対側で遮蔽部３７ａにＶ字状に結合された連通部３７ｂには治具２８が挿通可能な開口３７ｃが形成され、遮蔽部３７ａの下端と連通部３７ｂの下端とが治具２８を挿通可能な開口３７ｆを有する補強部３７ｅで連結される。遮蔽部３７ａの先端には治具２８が係合可能な切欠状の係止部３７ｄが形成される。ハウジング３６は、治具２８を挿通可能な開口３６ｂを有する隔壁３６ｃが設けられており、シャッター部材３７は、補強部３７ｅが隔壁３６ｃの上面に当接するように支軸３８まわりに捩じりばね３９によって付勢される。
【００４８】
図１８に示すように、治具２８の特別な操作方法を知らない者が、ボルト部材２１を操作しようとしてグリルカバー３５の治具挿入孔３５ｂから治具挿入経路Ｐに沿って治具２８を挿入すると、治具２８の先端部２８ａが切換機構３４Ｌのシャッター部材３７の遮蔽部３７ａに当接する（図１８（Ａ）参照）。治具２８を更に押し下げると、シャッター部材３７が隔壁３６ｃに当接して下方への揺動を規制されているため、治具２８の先端部２８ａは遮蔽部３７ａの上面を滑って支軸２８の上部のケーシング３６の内壁３６ａに当接し、ボルト支持部材２４の開口２４ｂに挿入することが不可能になる（図１８（Ｂ）参照）。
【００４９】

Therefore, when viewed from above, an opening 23b on the upper surface of the lower right bolt support member 23 is provided. Is exposed without being blocked by the bolt support member 22 on the upper right.
[0033]
The bolt member 20 supported by the lower right bolt support member 23 and the bolt member 21 supported by the upper left bolt support member 24 constitute the shaft adjusting member of the present invention. Switching mechanisms 34L and 34R for switching between a state in which the operation of the bolt members 20 and 21 by the jig 28 is allowed and a state in which the operation is prevented are provided on the left and right bracket bodies 13a and 13b, respectively. The left and right switching mechanisms 34L and 34R have the same structure, and details thereof will be described later.
[0034]
The right switching mechanism 34R is located above the opening 23b of the lower right bolt support member 23 and below the jig insertion hole 35a formed in the grill cover 35 that covers the radar device Sr. That is, the jig insertion hole 35a of the grill cover 35, the switching mechanism 34R on the right side, and the opening 23b of the bolt support member 23 on the lower right are located on a straight line constituting the jig insertion path P (see FIGS. 12 and 13). ing. Similarly, the left switching mechanism 34L is located above the opening 24b of the upper left bolt support member 24 and below the jig insertion hole 35b formed in the grill cover 35 that covers the radar device Sr. Yes. That is, the jig insertion hole 35b of the grill cover 35, the switching mechanism 34L on the left side, and the opening 24b of the bolt support member 24 on the upper left are located on a straight line constituting the jig insertion path P (see FIG. 13D). Yes.
[0035]
Next, the structures of the left and right switching mechanisms 34L and 34R will be described with reference to FIGS. Since the left and right switching mechanisms 34L and 34R have substantially the same structure, the structure of the left switching mechanism 34L will be described as a representative.
[0036]
The switching mechanism 34L includes a square cylindrical housing 36 whose upper and lower surfaces are open, and a shutter member 37 bent in an L shape is supported in a swingable manner via a support shaft 38 therein. The shutter member 37 includes a shielding portion 37a and a communication portion 37b extending from the support shaft 38 in directions orthogonal to each other, and a circular opening 37c into which the jig 28 can be inserted is formed at the center of the communication portion 37b. At the same time, a locking portion 37d with which the jig 28 can be engaged is formed at the tip of the communication portion 37b. The shutter member 37 is urged to a position along the inner wall 36a of the housing 36 by a torsion spring 39 supported by a support shaft 38. In this state, the shielding portion 37a is located between the upper and lower surfaces of the housing 36. Blocking.
[0037]
Next, the operation of the first embodiment of the present invention having the above configuration will be described.
[0038]
Adjustment of the object detection axis Ar of the radar device Sr is performed as follows. That is, when the actual object detection axis Ar of the radar device Sr is displaced in the vertical direction with respect to the target direction, the tip 28a of the jig 28 is moved to the head 20b of the lower right bolt member 20. The gear teeth 20c are engaged and rotated. At this time, the back surface of the front end portion 28a of the jig 28 is supported by the guide projection 23a of the bolt support member 23 so that the engagement between the front end portion 28a of the jig 28 and the gear teeth 20c of the bolt member 20 is not released. (See FIG. 8).
[0039]
When the lower right bolt member 20 is rotated and the stay 15b of the frame 15 is pushed forward, the radar device Sr swings upward with the upper two bolt members 19 and 21 as fulcrums, and the object detection axis Ar is moved. Adjusted upward. Conversely, when the stay 15b of the frame 15 is pulled back, the radar device Sr swings downward with the upper two bolt members 19 and 21 as fulcrums, and the object detection axis Ar is adjusted downward.
[0040]
Similarly, when the upper left bolt member 21 is rotated using the jig 28 and the stay 15c of the frame 15 is pushed forward, the radar device Sr swings rightward with the two bolt members 19 and 20 on the right side as fulcrums. The object detection axis Ar is adjusted to the right. Conversely, when the stay 15c of the frame 15 is pulled back, the radar device Sr swings leftward with the two bolt members 19 and 20 on the right as fulcrums, and the object detection axis Ar is adjusted leftward.
[0041]
As described above, even if the direction of the object detection axis Ar is shifted due to an error in assembly of the individual radar devices Sr, the direction of the object detection axis Ar can be correctly matched with the target direction.
[0042]
By the way, even if the axis adjustment of the radar device Sr is correctly performed, for example, if the user operates the bolt members 20 and 21 using the jig 28, the direction of the adjusted object detection axis Ar is deviated. There is a problem. In order to solve such a problem, a person who does not know a special operation method of the jig 28 cannot operate the bolt members 20 and 21.
[0043]
As shown in FIG. 12, a person who does not know a special operation method of the jig 28 tries to operate the bolt member 21 from the jig insertion hole 35b of the grill cover 35 along the jig insertion path P. Is inserted, the tip end portion 28a of the jig 28 comes into contact with the shielding portion 37a of the shutter member 37 of the switching mechanism 34L (see FIG. 12A). When the jig 28 is further pushed down, the shutter portion 37a is pressed downward, so that the shutter member 37 swings counterclockwise around the support shaft 38 against the torsion spring 39, and the tip of the communication portion 37b. The locking portion 37d pushes the side surface of the jig 28 (see FIG. 12B). As a result, since the jig 28 is shifted laterally from the jig insertion path P, the front end portion 28a is sandwiched between the inner wall 36a of the housing 36 and the front end of the shielding portion 37a of the shutter member 37, thereby supporting the bolt. It becomes impossible to insert into the opening 24b of the member 24 (see FIG. 12C).
[0044]
As shown in FIG. 13, a person who knows how to operate the jig 28 inserts the jig 28 obliquely from the jig insertion hole 35 b of the grill cover 35, and the tip 28 a is connected to the communicating portion of the shutter member 37. It is made to contact | abut to the latching | locking part 37d of the front-end | tip of 37b (refer FIG. 13 (A)). Subsequently, while the jig 28 is inserted between the locking portion 37 d and the inner wall 36 a of the housing 36, the communication portion 37 b of the shutter member 37 is counterclockwise around the support shaft 38 against the torsion spring 39. (See FIG. 13B). As a result, the tip 28a of the jig 28 is fitted into the opening 37c of the communication part 37b of the shutter member 37 (see FIG. 13C). When the jig 28 is further inserted along the jig insertion path P from this state, the distal end portion 28a of the jig 28 pushes down the shielding portion 37a and the shutter member 37 further swings counterclockwise. The front end portion 28a can be inserted into the opening 24b of the bolt support member 24 and meshed with the gear teeth 21c of the bolt member 21 (see FIG. 13D).
[0045]
As described above, since only those who know the special operation method of the jig 28 can operate the bolt members 20 and 21, the object detection shaft Ar that has been adjusted with the bolt members 20 and 21 being tampered with by delusions. Can be prevented from shifting. Further, since the jig insertion holes 35a and 35b of the grill cover 35, the openings 37c and 37c of the switching mechanisms 34L and 34R, and the bolt members 20 and 21 are linearly arranged along the jig insertion path P, the jig 28 Can be easily guided from the jig insertion holes 35a, 35b to the bolt members 20, 21.
[0046]

FIG. 14 is a plan view of the switching mechanism, FIG. 15 is a sectional view taken along line 15-15 in FIG. 14, and FIG. -16 sectional view, FIG. 17 is a perspective view of the shutter member, FIG. 18 is an operation explanatory diagram when the jig is operated improperly, and FIG. 19 is an operation explanatory diagram when the jig is operated properly. Since the left and right switching mechanisms 34L and 34R have substantially the same structure, the structure of the left switching mechanism 34L will be described as a representative example.
[0047]
The switching mechanism 34L includes a square cylindrical housing 36 whose upper and lower surfaces are open, and a shutter member 37 is supported in a swingable manner via a support shaft 38 therein. The shutter member 37 includes a shielding part 37a, a communication part 37b, and a reinforcing part 37e. The shielding part 37a is a plate-like member having no opening, and an opening 37c through which the jig 28 can be inserted is formed in the communication part 37b coupled to the shielding part 37a in a V shape on the opposite side of the support shaft 38. The lower end of the shielding part 37a and the lower end of the communication part 37b are connected by a reinforcing part 37e having an opening 37f through which the jig 28 can be inserted. A notch-shaped locking portion 37d with which the jig 28 can engage is formed at the tip of the shielding portion 37a. The housing 36 is provided with a partition wall 36c having an opening 36b through which the jig 28 can be inserted, and the shutter member 37 is a torsion spring around the support shaft 38 so that the reinforcing portion 37e contacts the upper surface of the partition wall 36c. 39 is energized.
[0048]
As shown in FIG. 18, a person who does not know the special operation method of the jig 28 tries to operate the bolt member 21 and moves the jig 28 along the jig insertion path P from the jig insertion hole 35b of the grill cover 35. When inserted, the distal end portion 28a of the jig 28 comes into contact with the shielding portion 37a of the shutter member 37 of the switching mechanism 34L (see FIG. 18A). When the jig 28 is further pushed down, the shutter member 37 abuts against the partition wall 36c and is prevented from swinging downward, so that the tip 28a of the jig 28 slides on the upper surface of the shielding part 37a and It abuts against the inner wall 36a of the upper casing 36 and cannot be inserted into the opening 24b of the bolt support member 24 (see FIG. 18B).
[0049]
As shown in FIG. 19, a person who knows a special operation method of the jig 28 inserts the jig 28 obliquely from the jig insertion hole 35 b of the grill cover 35, and uses the tip 28 a as the shielding portion of the shutter member 37. It is made to contact | abut to the latching | locking part 37d of the front-end | tip of 37a (refer FIG. 19 (A)). Subsequently, while the jig 28 is inserted between the locking portion 37 d and the inner wall 36 a of the housing 36, the shielding portion 37 a of the shutter member 37 is rotated clockwise around the support shaft 38 against the torsion spring 39. Swing (see FIG. 19B). As a result, the tip 28a of the jig 28 is fitted into the opening 37c of the communication portion 37b of the shutter member 37. Therefore, when the jig 28 is further inserted along the jig insertion path P as it is, the tip of the jig 28 is inserted. 28a passes through the opening 37f of the reinforcing portion 37e. As a result, the front end portion 28a of the jig 28 can pass through the opening 24b of the bolt support member 24 and mesh with the gear teeth 21c of the bolt member 21 (see FIG. 19C).
[0050]
Also according to the second embodiment, only those who know the special operation method of the jig 28 can operate the bolt members 20 and 21. Therefore, the bolt members 20 and 21 are subject to the paralysis and adjusted with great effort. It is possible to prevent the detection axis Ar from deviating. Note that the reinforcing portion 37e of the shutter member 37 of the second embodiment can be omitted.
[0051]

I was able to While maintaining the operability of the shaft adjusting member, it is possible to prevent the shaft adjusting member from being manipulated unreasonably.
[0069]
Also Especially in claim 1 According to the invention, since the switching mechanism is provided with at least a shielding portion that can prevent the insertion of the jig and a communication portion having an opening into which the jig can be inserted, the shielding portion is positioned on the jig insertion path in a normal state. The jig can be blocked by the shielding part so that the shaft adjustment member cannot be inserted, and the communication part can be positioned in the jig insertion path instead of the shielding part by inserting the jig by a predetermined insertion method. Thus, the jig can be inserted up to the shaft adjusting member through the opening of the communication portion.

Since the switching mechanism is configured by the housing and the elastic member that urges the communicating portion of the shutter member along the inner wall of the housing, in the normal state, the communicating portion of the shutter member is aligned with the inner wall of the housing, Operation of the shaft adjustment device can be prevented by making it impossible to insert a jig into the opening, and the shutter member swings around the support shaft against the elastic member by inserting the jig by a predetermined insertion method. Thus, the jig can be inserted into the opening of the communication portion of the shutter member, and the operation of the shaft adjusting device can be permitted.
[0071]
Also Especially in claim 3 According to the invention, when the jig is inserted by a predetermined insertion method, the jig is inserted between the communication portion and the inner wall of the housing, and the shutter member is swung around the support shaft against the elastic member. Since the opening of the communication portion faces the jig insertion path, the jig can be inserted through the opening to the shaft adjusting member.
[0072]
Also Especially in claim 4 According to the invention, when the jig is inserted by a method other than the predetermined insertion method, the shielding portion of the shutter member swings around the support shaft and cooperates with the inner wall of the housing to prevent the jig from being inserted. It is possible to reliably prevent the jig from reaching the shaft adjusting member.
[0073]
Also Especially in claim 5 According to the invention, the switching mechanism has a partition that has an opening into which a jig can be inserted and closes the jig insertion path, and a shutter member that moves between a position at which the opening of the partition is opened and a position at which the opening is closed. Therefore, in the normal state, the opening of the partition wall is opened by covering the opening of the partition wall with a shutter member to prevent the insertion of the jig, and inserting the jig by a predetermined insertion method and moving the shutter member. The jig can be inserted.
[0074]
Also In particular, claim 6 According to the invention, since the resilient member urges the shutter member from the position where the opening of the partition wall is opened to the position where it is closed, the opening of the partition wall can be reliably covered with the shutter member in the normal state.
[0075]
Also Especially in claim 7 According to the invention, the switching mechanism is urged so that the cylindrical shutter member rotatably supported by the support shaft, the housing surrounding the shutter member, and the opening penetrating the shutter member face the inner wall of the housing. In the normal state, the shutter member opening is opposed to the inner wall of the housing to prevent the jig from being inserted, and the jig is inserted by a predetermined insertion method so that the shutter member is inserted into the bullet member. By rotating it around the support shaft against this, insertion of the jig can be permitted with the direction of the opening of the shutter member along the jig insertion path.
[0076]
Also Especially in claim 8 According to the invention, since the locking portion is provided in the shutter member, the shutter member can be easily rotated by engaging the jig with the locking portion.
[0077]
Also Especially in claim 9 According to the invention, the switching mechanism has a housing surrounding the jig insertion path, and one end side supported by the inside of the housing via the support shaft, and swings between a position where the jig insertion path is opened and a position where the jig insertion path is closed. In the normal state, the jig insertion path is blocked by the shutter member to prevent the jig from being inserted, and the jig is inserted by a predetermined insertion method so that the shutter member is a resilient member. By swinging around the support shaft against this, the jig insertion path can be opened to allow the jig to be inserted.
[0078]
Also Especially in claim 10 According to the invention, since the jig insertion hole, the opening of the switching mechanism, and the shaft adjustment member are positioned on a straight line, the jig can be easily guided from the jig insertion hole to the shaft adjustment member.
