【0001】
【発明の属する技術分野】
本発明は、例えば気化器等を操作するケーブルを被操作機器たる気化器本体に固定する取付け構造に関する。
【0002】
【従来の技術】
図5は実公昭61−41967号公報に示される従来の操作用ケーブルが気化器に取付けられた状態を示す側面図、図6はその要部の分解斜視図である。
【0003】
図5および図6において、透孔02aとこれを側方に開口する切欠ぎ02bとが形成された取付け板02を気化器01に固設し、操作用ケーブル03が内挿されたケーブルアウター04を、その端部の調整おねじ部04aにおいて上記透孔02aに挿通して、その両側を調整ナット05a,05bで締付け固定する。上記操作用ケーブル03の先端は気化器01のスロットルレバー07に連結されており、またケーブルアウター04の先端部にはブーツ06が設けられる。
【0004】
上記調整おねじ部04aの中央部には、外径が前記取付け板02の切欠ぎ02bの幅とほぼ同一で、長さが上記取付け板02の厚さとほぼ同一の小径部04bが形成され、調整おねじ部04aはこの小径部04bにおいて切欠ぎ02bを介して透孔02a内に出入自在になっている。
【0005】
ケーブルアウター04を取付け板02に取付けるには、調整ナット05a,05bをケーブルアウター04の小径部04bの両側でその小径部04bから多少離れた位置に配しておき、ケーブルアウター04を小径部04bにおいて切欠ぎ02bを介して透孔02aに導入させ、次にこれを前後方向の所定位置まで移動させた後、両調整ナット05a,05bを回転させて取付け板02の両面を締付け固定する。これはその取外しに際してもほぼ同様である。
【0006】
【解決しようとする課題】
前記従来の操作用ケーブル固定構造においては、ケーブルアウター04の小径部04bの長さが短いので、調整ナット05a,05bを両方とも両側の調整おねじ部04aにねじ込んでおかないと、調整おねじ部04aを切欠ぎ02bに通すことができず、操作用ケーブルの組付けに時間がかかっていた。
【0007】
【課題を解決するための手段および効果】
前記従来の課題を解決するために、請求項1記載の発明は、透孔と該透孔を側方に開口する切欠ぎとが形成された取付け板を被操作機器に固設するとともに、操作用ケーブルが内挿されたケーブルアウターの端部に設けられた調整おねじ部を上記取付け板の上記透孔に挿通し、該取付け板の両面を調整ナットで締付け固定する構造において、上記調整おねじ部に、上記取付け板の上記切欠ぎと上記調整ナットとが通過できる外径および上記取付け板の厚さと上記調整ナット1個分の厚さとの和以上の長さを有する小径部が形成されたことを特徴とする操作用ケーブル固定構造である。
【0008】
請求項1記載の発明は上記のとおり構成され、調整おねじ部に、取付け板の切欠ぎと調整ナットとが通過できる外径および上記取付け板の厚さと上記調整ナット1個分の厚さとの和以上の長さを有する小径部が形成されているので、調整ナットの一方と取付け板とを同時に小径部内に位置させることができる。したがって調整ナットの一方はあらかじめ調整おねじ部にねじ込んでおく必要はないので、組付け性が向上する。
【0009】
また請求項2記載の発明は、前記請求項1記載の発明において、上記ケーブルアウターの先端部を覆い、かつ上記操作用ケーブルを貫通させて、弾性材料より成るブーツが取付けられたことを特徴とするものである。
【0010】
したがって請求項2記載の発明においては、ケーブルアウター内部へのダスト侵入が防止されるとともに、小組みされた状態で調整ナットの脱落が防止される。
【0011】
次に請求項3記載の発明は、前記請求項2記載の発明において、上記ブーツに上記調整ナットのねじ山に接するリップ部が形成されたことを特徴とするものである。
【0012】
したがって請求項3記載の発明においては、小組状態の時、小径部にある調整ナットがケーブルアウター先端方向に動くと、ブーツに形成されたリップ部が調整ナットとケーブルアウターの間に喰込み、楔効果によって、調整ナットの抜け止め効果が更に高まる。
【0013】
次に請求項4記載の発明は、前記請求項2記載の発明においては、上記小径部の最先端と上記ブーツの後端との間の上記ケーブルアウターに、上記調整ナットが回転せずには通過できないストッパー部が形成されたことを特徴とするものである。
【0014】
したがって請求項4記載の発明においては、調整ナットとブーツとの間の隙間が確保され、小組状態の時に調整ナットがブーツに接触することはないから、組立時に調整ナットやブーツが脱落する恐れがない。
【0015】

【0027】
また、上記ブーツ16には、組付けの段階で調整ナット5bのねじ山に接触するリップ部16aが形成されている。
【0028】
操作用ケーブル3の取付けに際しては、まず図3(a)に示されるように、操作用ケーブル3が内挿されたケーブルアウター14の調整おねじ部14aの奥まで一方の調整ナット5aをねじ込むとともに、他方の調整ナット5bを調整おねじ部14aの先端14cからねじ込んで小径部14bまで到達させておく。それからブーツ16を調整おねじ部14aの先端14cに装着する。この状態では調整ナット5bは小径部14b内を回転せずに移動することができる。
【0029】
次に調整ナット5bを小径部14b内のケーブルアウター14先端側に寄せておいて、小径部14bの奥部を取付け板2の切欠ぎ2bから透孔2a内へ挿入する(図3(a))。

その後、図3(b)に示されるように、ケーブルアウター14の調整おねじ部14aを取付け板2の透孔2a内の所定位置まで移動させ、取付け板2の両面を調整ナット5a,5bで締付け固定する。
【0031】
本実施例においても、ケーブルアウター14の小径部14bの外径が、取付け板2の切欠ぎ2bを通過でき、また調整ナット5bが回転せずに通過できる寸法になっている。そして小径部14bの長さLは、取付け板2の厚さtと調整ナット5bの厚さtとの和に、さらにブーツ16の嵌合部の長さtを加えた以上の寸法になっている。したがって、調整ナット5bと取付け板2とを同時に小径部14b内に位置させることができる。その結果、調整ナット5bはあらかじめ調整おねじ部14aの先端14cにねじ込んでおく必要はないので、組付け性が向上する。
【0032】
本実施例ではまた、ケーブルアウター14の先端部を覆い、かつ操作用ケーブル3を貫通させて、弾性材料から成るブーツ16が取付けられているので、ケーブルアウター14内部へのダスト侵入が防止されるとともに、小組みされた状態で調整ナット5a,5bの脱落が防止される。
【0033】
さらに本実施例では、上記ブーツ16に、組付けの段階で調整ナット5bのねじ山に接触するリップ部16aが形成されているので、小組状態の時、小径部14bにある調整ナット5bがケーブルアウター14先端方向に動くと、ブーツ16に形成されたリップ部16aが調整ナット5bとケーブルアウター14の間に喰込み、楔効果によって、調整ナット5bの抜け止め効果が更に高まる。
【0034】
次に図4は本発明の第3の実施例における操作用ケーブル取付け部を示す拡大図であって、(a)は取付け過程を示す図、(b)は取付け完了状態を示す図である。
【0035】
本実施例においても、操作用ケーブル3が内挿されたケーブルアウター24の端部に調整おねじ部24aが設けられ、調整ナット5a,5bが螺合できるようになっている。またケーブルアウター24の先端部を覆い、かつ上記操作用ケーブル3を貫通させて、弾性材料から成るブーツ26が取付けられる。

操作用ケーブル3の取付けに際しては、まず図4(a)に示されるように、ケーブルアウター24の調整おねじ部24aの奥まで一方の調整ナット5aをねじ込むとともに、他方の調整ナット5bを調整おねじ部24aの先端からねじ込んで小径部24bまで到達させておく。それからブーツ26を調整おねじ部24aの先端に装着する。この状態では調整ナット5bが小径部24b内を回転せずに移動することができる。
【0039】
次に調整ナット5bを小径部24b内のケーブルアウター24先端側に寄せておいて、小径部24bの奥部を取付け板2の切欠ぎ2bから透孔2a内へ挿入する(図4(a))。
【0040】
その後、図4(b)に示されるように、ケーブルアウター24の調整おねじ部24aを取付け板2の透孔2a内を所定の位置まで移動させ、取付け板2の両面を調整ナット5a,5bで締付け固定する。
【0041】
本実施例においても、ケーブルアウター24の小径部24bの外径は、取付け板2の切欠ぎ2bを通過でき、また調整ナット5bが回転せずに通過できる寸法になっている。一方小径部24bの長さLは、取付け板2の厚さtと調整ナット5bの厚さtとの和以上の寸法になっている。したがって調整ナット5bと取付け板2とを同時に小径部24b内に位置させることができる。その結果、調整ナット5bはあらかじめ調整おねじ部の先端24cにねじ込んでおく必要はないので、組付け性が向上する。
