【発明の属する技術分野】
本発明は、釣用リールのねじ操作構造、特に、釣用リールのリール本体に取り付けられる釣用リールのねじ操作構造に関する。
【０００２】
【従来の技術】
従来、釣用リールには、リール本体内部に組み込まれた各種の機構を調節できるようにしたねじ操作構造が広く採用されている。このようなねじ操作構造としては、たとえば、リアドラグ型スピニングリールのリアドラグ機構のドラグ力を調節するためのねじ操作構造がある。
【０００３】
従来のスピニングリールのリアドラグ機構に用いられるねじ操作構造は、リール本体後部に形成された雄ねじ部を有するねじ込み部と、雄ねじ部に螺合可能な有底円筒状の操作つまみと、リアドラグ機構を押圧する押圧部材と、操作つまみを押圧部材に固定する固定ボルトとを有している。このとき、操作つまみがねじ込み部から脱落すると、操作つまみに固定された押圧部材が抜け落ち、リアドラグ機構が分解するなどの不具合を生じる。このため、従来のスピニングリールでは、押圧部材がねじ込み部から抜け落ちないように、抜け止め部材がねじ込み部に装着されている。抜け止め部材は、たとえば半円状のバネ部材であり、両端がねじ込み部を貫通して押圧部材を係止している。このように、ねじ込み部に装着された抜け止め部材によって、押圧部材が後方に抜け落ちないように抜け止めされているので、押圧部材に固定された操作つまみもリール本体から抜け落ちないようになっている。
【０００４】
従来のねじ操作構造では、まず、リール本体に組み付けられたリアドラグ機構の後部に押圧部材を装着する。次に、ねじ込み部に抜け止め部材を装着して、押圧部材を抜け止めする。最後に、操作つまみを、ねじ込み部に螺合させた状態で、固定ボルトによって押圧部材に固定する。

【発明が解決しようとする課題】
従来の構成で、操作つまみをリール本体に取り付けるためには、操作つまみを固定ボルトで押圧部材に固定する前に、抜け止め部材をねじ込み部に装着して押圧部材を抜け止めしておく必要がある。このとき、リール本体の後部には、複雑なリアドラグ機構が内蔵され、限られたスペースしか確保されていないので、抜け止め部材の形状および組み付け位置は制約を受ける。こうした抜け止め部材に対する制約が、ねじ操作構造の構成と組み立て作業とを複雑なものにしている。
【０００７】
本発明の課題は、ねじ操作構造において、操作つまみ（操作部材およびねじ部材）を容易に装着することができ、かつ操作つまみが抜け落ちないようにすることである。
【０００８】
【課題を解決するための手段】
発明１に係る釣用リールのねじ操作構造は、釣用リールのリール本体に取り付けられるねじ操作構造であって、ねじ込み部と、ねじ部材と、保持部材とを備えている。ねじ込み部は、リール本体に設けられた雄ねじ部と、雄ねじ部と一体に形成される筒状部とを有している。ねじ部材は、雄ねじ部に螺合可能な雌ねじ部を有し、雄ねじ部の径方向外方から雄ねじ部に装着可能に分割されている。この分割されたねじ部材を連結した状態で、ねじ込み部の筒状部は、ねじ部材の雌ねじ部の内径より大径になるように形成されている。保持部材は、ねじ部材をねじ込み部の雄ねじ部に螺合可能な状態で保持している。
【０００９】
このねじ操作構造では、ねじ部材が、ねじ込み部の雄ねじ部に分割して装着可能になっており、保持部材によって雄ねじ部に保持される。そして、保持部材によって保持されたねじ部材を回転させることによって、リール本体に組み込まれた機構は操作される。このとき、ねじ部材は、雌ねじ部の内径より大径に形成されたねじ込み部の筒状部によって、ねじ込み部から抜け落ちないように規制される。
【００１０】
ここでは、ねじ部材が分割されているので、雌ねじ部の内径より大径の筒状部が形成されていても、ねじ部材を雄ねじ部に容易に装着することができる。また、ねじ込み部の筒状部が雌ねじ部の内径より大径になっているので、抜け止め部材を用いることなく、ねじ部材の抜け落ちを筒状部によって規制することができる。
【００１１】
発明２に係る釣用リールのねじ操作構造は、発明１に記載のねじ操作構造において、保持部材が、ねじ部材の外形に接触させるように形成され、ねじ部材を保持する止め輪部材となっている。この場合、保持部材が、ねじ部材を保持する止め輪部材となっているので、ねじ部材の雌ねじ部の内径より大径の筒状部がねじ込み部に形成されていても、止め輪部材によって、分割されたねじ部材をねじ込み部の雄ねじ部に容易に保持することができる。
【００１２】
発明３に係る釣用リールのねじ操作構造は、発明１に記載のねじ操作構造において、保持部材が、分割されるねじ部材を連結可能なボルト部材となっている。この場合、保持部材が、ねじ部材を連結可能なボルト部材となっているので、ねじ部材の雌ねじ部の内径より大径の筒状部がねじ込み部に形成されていても、ボルト部材によって、分割されたねじ部材をねじ込み部に容易に保持することができ、ボルト連結後のねじ部材の一体性を確保できる。
【００１３】
発明４に係る釣用リールのねじ操作構造は、発明１から３のいずれかに記載のねじ操作構造において、ねじ部材の外周面に回転不能に装着される操作部材をさらに備えている。この場合、ねじ操作構造が、ねじ部材の外周面に回転不能に装着される操作部材をさらに備えているので、ねじ操作構造の操作性を向上することができる。このとき、ねじ部材はあらかじめ保持部材で保持されているので、操作部材は容易にねじ部材に装着することができる。
【００１４】
発明５に係る釣用リールのねじ操作構造は、発明１に記載のねじ操作構造において、ねじ部材の外周面に回転不能に装着され、保持部材と一体に形成された操作部材をさらに備えている。この場合、ねじ操作構造が、保持部材と一体に形成された操作部材をさらに備えているので、保持部材を用いることなく、分割されたねじ部材を保持することができる。また、ねじ操作構造としての部材数が減るために、分割されたねじ部材をねじ込み部に装着した後の組み立てが容易になる。
【００１５】
発明６に係る釣用リールのねじ操作構造は、発明４又は５に記載のねじ操作構造において、ねじ部材の外径が、筒状部の外径より大きくなっている。この場合、ねじ部材の外径が筒状部の外径より大きくなっているので、操作部材を筒状部側からねじ部材の外形に容易に装着することができる。
発明７に係る釣用リールのねじ操作構造は、発明４から６のいずれかに記載のねじ操作構造において、操作部材が、筒状部を収納可能な収納部を有している。この場合、操作部材が、筒状部を収納可能な収納部を有しているので、筒状部を保護することができる。また、押圧部材を収納部に一体に形成すると、筒状部を保護できるだけでなく、ねじ込み部への操作部材の取り付け作業が容易になる。
【００１６】
発明８に係る釣用リールのねじ操作構造は、発明４から６のいずれかに記載のねじ操作構造において、操作部材が、ねじ部材を回動可能に操作するための径方向に突出した突起部を有している。この場合、操作部材が、ねじ部材を回動可能に操作するための突起部を有しているので、突起部を用いて操作部材を操作することで、ねじ部材を容易に回動させることができる。また、突起部をねじ部材に対する操作部材の位置決めに利用することで、操作部材をねじ部材に容易に装着することができる。
【００１７】
発明９に係る釣用リールのねじ操作構造は、発明４から８のいずれかに記載のねじ操作構造において、ねじ部材が操作部材との装着面に径方向に突出した突出部を形成しており、操作部材が、突出部に係合する凹部を有し、突出部と凹部とが係合した状態でねじ部材とともに回動する。この場合、ねじ部材の突出部と操作部材の凹部とが係合した状態で、操作部材がねじ部材とともに回動するので、操作部材に対して行った操作をねじ部材へと有効に伝達することができる。また、ねじ部材の突出部と操作部材の凹部とを係合可能にしたことで、操作部材をねじ部材に容易に位置決めして装着することができる。
【００１８】
発明１０に係る釣用リールのねじ操作構造は、発明４から９のいずれかに記載のねじ操作構造において、ねじ込み部がスピニングリールの前記リール本体から後方に突出しており、操作部材がスピニングリールのリアドラグ機構の操作つまみとなっている。この場合、操作部材がスピニングリールのリアドラグ機構の操作つまみとなっているので、リアドラグ機構の操作つまみが、ねじ込み部に容易に装着可能で、ねじ込み部から抜け落ちないようにすることができる。
【００１９】
発明１１に係る釣用リールのねじ操作構造は、発明４から９のいずれかに記載のねじ操作構造において、ねじ込み部が両軸受リールの前記リール本体から側方に突出しており、操作部材がキャスティングコントロール機構の操作つまみとなっている。この場合、操作部材が両軸受リールのキャスティングコントロール機構の操作つまみとなっているので、キャスティングコントロール機構の操作つまみが、ねじ込み部に容易に装着可能で、ねじ込み部から抜け落ちないようにすることができる。
【００２０】
【発明の実施の形態】
〔リール本体およびねじ操作構造の構成〕
図１に示す本発明の一実施形態を採用したスピニングリールは、主に、ハンドル１０を備えたリール本体１と、リール本体１の前部に回転自在に支持されたロータ２と、ロータ２の前部に配置され釣り糸を巻き取るためのスプール３とを備えている。ここで、スプール３には釣り糸を巻き取るためのベール４が、ベール４には釣り糸を案内するラインローラ５が、取り付けられている。
【００２１】
リール本体１は、図１に示すように、ボディ１ａを有しており、ボディ１ａの上部にはスピニングリールを釣り竿に取り付けるための竿取付部１ｂが形成されている。ボディ１ａの内部には、ロータ２を回転させるためのロータ駆動機構７と、スプール３をロータ２の回転軸芯に沿って前後方向に移動させることで、スプール３に釣り糸を均一に巻き取るためのレベルワインド駆動機構８とが設けられている。ボディ１ａの後部には、リアドラグ機構９が内蔵されている。このリアドラグ機構９を操作するために、ねじ操作構造６がボディ１ａの後部に装着されている。
【００２２】
ロータ駆動機構７は、図１に示すように、ハンドル軸１０ａとともに回転するマスターギア１１と、このマスターギア１１と噛み合うピニオンギア１２とを有している。ピニオンギア１２は筒状に形成されており、その前部はロータ２の中心部を貫通してスプール３側に延びている。ピニオンギア１２は、ボディ１ａに支持されたボールベアリング１３によって回転自在に支持されている。そして、ピニオンギア１２の中心部を、スプール軸１４が回転軸芯に沿って前後方向に移動自在に貫通している。ピニオンギア１２の内径とスプール軸１４の外径との間には、所定の隙間が確保されている。
【００２３】
レベルワインド駆動機構８は、図１に示すように、ハンドル１０によってハンドル軸１０ａを回転させることで、スプール軸１４を前後方向に運動させる機構である。レベルワインド駆動機構８は、スプール軸１４の下奥側に配置された駆動軸１５と、駆動軸１５に沿って前後方向に移動するスライダ１６と、駆動軸１５の下方に配置されたガイド軸１７と、駆動軸１５の先端に固定されピニオンギア１２に噛み合う中間ギア（図示しない）とを有している。駆動軸１５とガイド軸１７とは、スプール軸１４と平行に配置されている。
【００２４】
リアドラグ機構９は、図２に示すように、円筒状のブッシュ１８と、複数の摩擦プレート１９ａ，２０ａからなる第１および第２摩擦係合部１９，２０と、第１摩擦係合部１９の摩擦プレート１９ａ押し付け用のコイルスプリング２１と、第２摩擦プレート２０ａ押し付け用の押圧部材２２とから構成されている。ブッシュ１８は、スプール軸１４後部の外周に嵌め込まれている。このブッシュ１８に対して、スプール軸は回動不能かつ摺動自在になっている。ブッシュ１８後部の外周面上には第１フランジ部２３が、ブッシュ１８前部の外周面上には第２フランジ部２４が、それぞれ設けられている。そして、第１および第２フランジ部２３，２４に、第１および第２摩擦係合部１９，２０の摩擦プレート１９ａ，２０ａがそれぞれ配置されている。第１摩擦係合部１９の後部にはコイルスプリング２１が装着され、第２摩擦係合部２０の後部には押圧部材２２が配置されている。
【００２５】
ねじ操作構造６は、図２から図４に示すように、リール本体１のボディ１ａ後部に設けられたねじ込み部２６と、第１および第２ねじ部材２８，２９と、第２ねじ部材２９をねじ込み部２６に保持する保持部材３０と、第１および第２操作部材３１，３２とを備えている。ねじ込み部２６は、ボディ１ａに形成された雄ねじ部２７と、雄ねじ部２７と一体に形成される筒状部３３とを有している。第１および第２ねじ部材２８，２９には、ねじ込み部２６の雄ねじ部２７に螺合可能な雌ねじ部３４ａ，３４ｂがそれぞれ設けられている。筒状部３３は、第１および第２ねじ部材２８，２９の雌ねじ部３４ａ，３４ｂの内径より大径となるように形成されている。
【００２６】
第１および第２ねじ部材２８，２９は、図２から図４に示すように、軸方向に半円筒状に分割され、第１および第２突き合わせ部３５ａ，３６ａ（３５ｂ，３６ｂ）が、両ねじ部材２８，２９にそれぞれ形成されている。第１ねじ部材２８は雄ねじ部２７後方側で、第２ねじ部材２９は雄ねじ部２７前方側で、ねじ込み部２６に螺合可能に装着されている。第１および第２ねじ部材２８，２９の第１突き合わせ部３５ａ，３５ｂには、径方向に突出した突出部３８ａ，３８ｂが外周面上にそれそれ形成されている。第２ねじ部材２９と押圧部材２２との間には、第２ねじ部材２９の動作を押圧部材２２に伝達するために、押圧部材２２を回転不能かつ軸方向移動可能に係止する係止部３７が配置されている。
【００２７】
保持部材３０は、図４に示すように、第２ねじ部材２９をねじ込み部２６の雄ねじ部２７に螺合可能な状態で保持できる止め輪部材３９となっている。止め輪部材３９は、第２ねじ部材２９の外形に沿ってＣ型に成型され、第２ねじ部材２９に取り付けられている。このＣ型に成型された止め輪部材３９は、第２ねじ部材２９を、中心方向に向けて付勢して弾性係止可能になっている。このとき、止め輪部材３９のＣ字の連結していない部分が、第２ねじ部材２９の突出部３８ｂに嵌合される。
【００２８】
第１操作部材３１は、図２および図３に示すように、有底円筒状に形成され、筒状部３３を収納可能な収納部３３ａを有している。収納部３３ａの底部には、押圧部４０が一体に形成されている。第１操作部材３１は、ねじ込み部２６の雄ねじ部２７外周に螺合させた第１ねじ部材２８に装着させている。このとき、押圧部４０は、第１摩擦係合部１９の後部に装着されたコイルスプリング２１に直列に連結される。
【００２９】
第２操作部材３２は、図２および図４に示すように、円筒状に形成され、第２ねじ部材２９を回動可能に操作するための径方向に突出した突起部４１を有している。第２操作部材３２は、第１操作部材３１の前方で、第２ねじ部材２９に取り付けられた保持部材３０に装着させている。
第１および第２操作部材３１，３２は円筒内面に形成された凹部４２ａ，４２ｂを有し、この凹部４２ａ，４２ｂと第１および第２ねじ部材２８，２９の突出部３８ａ，３８ｂとが嵌合可能になっている。ここで、凹部４２ａ，４２ｂと突出部３８ａ，３８ｂとを嵌合させた後、凹部４２ａ，４２ｂから突出部３８ａ，３８ｂが抜け出さないように、凹部４２ａ，４２ｂの底部には規制部４３ａ，４３ｂが形成されている。この規制部４３ａ，４３ｂは、凹部４２ａ，４２ｂの底部から第１および第２ねじ部材２８，２９の中心に向けて突出した突起で構成されている。
【００３０】
〔リール本体およびねじ操作構造の動作〕
リール本体１からの糸繰り出し時には、ベール４を糸開放側に倒す。そして、釣り竿をキャスティングすると、スプール３から釣り糸が繰り出される。糸巻き取り時には、ベール４を糸巻取側に戻す。この状態でハンドル１０を糸巻取方向に回転させると、この回転力がハンドル軸１０ａ及びマスターギア１１を介してピニオンギア１２に伝達される。ピニオンギア１２に伝達された回転力は、ピニオンギア１２の前部においてロータ２を回転させる。一方で、ピニオンギア１２に伝達された回転力は、ピニオンギア１２に噛み合う中間ギア（図示しない）を介して駆動軸１５を回転させる。このとき、駆動軸１５の螺旋溝に噛み合うスライダ１６が、ガイド軸１７に案内され前後方向に移動する。スライダ１６が移動すると、スライダ１６とともにスプール軸１４とスプール３とが前後方向に往復移動する。こうしたロータ２の回転とスプール３の前後移動とによって、ベール４およびラインローラ５から案内される釣り糸は、スプール３の外周に前後方向に均一に巻き取られる。
【００３１】
リアドラグ機構９は、第１および第２操作部材３１，３２を回転させることによって、スプール３に対するドラグ力の強弱を調節するためのものである。リール本体１後部の第１操作部材３１を締め付けると、第１操作部材３１と一体に形成された押圧部４０が前方へと移動し、押圧部４０に連結されたコイルスプリング２１が押し込まれる。すると、第１摩擦係合部１９の複数の摩擦プレート１９ａ面が互いに近接し、ブッシュ１８の第１フランジ部２３が複数の摩擦プレート１９ａによって挟持される。このように、ブッシュ１８の第１フランジ部２３が押圧されることによって、ブッシュ１８に対して回動不能なスプール軸１４も回転しにくくなり、スプール３に作用するドラグ力は強くなる。一方、第１操作部材３１を弛めると、押圧部４０は後方へと移動し、コイルスプリング２１の押し込まれた状態が徐々に解除される。すると、摩擦プレート１９ａによる第１フランジ部２３の押圧が解除されて、ブッシュ１８に対して回動不能なスプール軸１４は回転しやすくなり、スプール３に作用するドラグ力は弱くなる。
【００３２】
第２操作部材３２を締め付けると、第２操作部材３２とともに第２ねじ部材２９が回転する。すると、第２ねじ部材２９と押圧部材２２との間に配置された係合部３７を介して、押圧部材２２がスプール軸１４に沿って前方に移動する。この押圧部材２２の移動によって、第２摩擦係合部２０の複数の摩擦プレート２０ａ面が互いに近接し、ブッシュ１８の第２フランジ部２４が摩擦プレート２０ａによって挟持される。このようにブッシュ１８の第２フランジ部２４が押圧されることによって、ブッシュ１８に対して回動不能なスプール軸１４も回転しにくくなり、スプール３に作用するドラグ力は強くなる。一方、第２操作部材３２を弛めると、押圧部材２２は、スプール軸１４に沿って後方へと移動し、第２摩擦係合部２０から離れる方向へと引き戻される。すると、摩擦プレート２０ａによる第２フランジ部２４の押圧が解除されて、ブッシュ１８に対して回動不能なスプール軸１４は回転しやすくなり、スプール３に作用するドラグ力は弱くなる。
【００３３】
〔ねじ操作構造の組立手順〕
ねじ操作構造６を組み立てる際には、まず、分割された第２ねじ部材２９をねじ込み部２６の雄ねじ部２７前方に螺合させ取り付ける。つづいて、Ｃ型に形成された止め輪部材３９を第２ねじ部材２９の外周面に装着し、第２ねじ部材２９をねじ込み部２６に固定する。そして、円筒状に形成された第２操作部材３２を筒状部３３側から第２ねじ部材２９に向けて嵌挿し、第２操作部材３２の円筒内面に形成された凹部４２ｂを第２ねじ部材２９の第１突き合わせ部３５ｂに設けられた突出部３８ｂに嵌めあわせる。次に、分割された第１ねじ部材２８を、ねじ込み部２６の雄ねじ部２７後方に螺合させ取り付ける。つづいて、有底円筒状に形成された第１操作部材３１の底部を筒状部３３に対向させて、第１操作部材３１の底部に形成された押圧部４０をねじ込み部２６内部に挿入しながら、第１操作部材３１の円筒部を第１ねじ部材２８に嵌め込む。そして、第１操作部材３１の円筒内面に形成された凹部４２ａを、第１ねじ部材２８に設けられた突出部３８ａに嵌めあわせる。
【００３４】
このように組み立てられる本実施形態のねじ操作構造６では、筒状部３３が第１および第２ねじ部材２８，２９の雌ねじ部３４ａ，３４ｂのねじ山内径より大径に形成されていても、両ねじ部材２８，２９は分割されているのでねじ込み部２６に容易に装着することができる。また、両ねじ部材２８，２９の外形を筒状部３３の外形より大きくしておけば、第１および第２操作部材３１，３２は両ねじ部材２８，２９に容易に装着することができる。
【００３５】
一方で、第１および第２操作部材３１，３２や第１および第２ねじ部材２８，２９をねじ込み部２６に容易に装着できるようにしたとしても、両操作部材３１，３２と両ねじ部材２８，２９とがねじ込み部２６から抜け落ちないように考慮しておくことは、リアドラグ機構９が分解するなどの不具合を防止する意味で重要である。本実施形態のねじ操作構造６では、両ねじ部材２８，２９の雌ねじ部３４ａ，３４ｂのねじ山内径より大径に形成されたねじ込み部２６の筒状部３３によって、両ねじ部材２８，２９はねじ込み部２６からの抜け落ちが規制されている。また、両操作部材３１，３２の凹部４２ａ，４２ｂが両ねじ部材２８，２９の突出部３８ａ，３８ｂに嵌め込まれることで、両操作部材３１，３２は両ねじ部材２８，２９に対して回転不能かつ軸方向移動不能になっている。このことから、両ねじ部材２８，２９の抜け落ちさえ規制しておけば、両ねじ部材２８，２９に装着された両操作部材３１，３２もねじ込み部２６から抜け落ちることはない。
【００３６】
以上のことから、本実施形態のねじ操作構造６では、リアドラグ機構９の機能はそのままで、操作つまみ（第１および第２操作部材３１，３２と第１および第２ねじ部材２８，２９）をねじ込み部２６に容易に装着することができる。また、抜け止め部材を用いることなく、両操作つまみがねじ込み部２６から抜け落ちないようにすることができる。
【００３７】
〔他の実施形態〕
（ａ）前記実施形態では、第１および第２ねじ部材２８，２９をねじ込み部２６の雄ねじ部２７に保持する形態の一つとして、第１ねじ部材２８には保持部材３０を用い、第２ねじ部材２９には保持部材３０を用いない場合の例を示したが、ねじ部材に対して保持部材３０を配置するかどうかは前記実施形態に限定されず、ねじ部材と操作部材とを容易に組み立てることができれば、保持部材３０はどのように配置しても良い。
【００３８】
（ｂ）前記実施形態では、第２ねじ部材２９をねじ込み部２６に保持する保持部材の形態の一つとして、止め輪部材３９を用いた場合の例を示したが、保持部材は、前記実施形態に限定されず、ねじ部材と操作部材とを容易に組み立てることができれば、ボルト部材のようなものでも良い。
（ｃ）前記実施形態では、第１操作部材３１に押圧部４０を一体に形成する場合の例を示したが、第１操作部材３１の構成は、前記実施形態に限定されず、第１操作部材３１をねじ込み部２６に容易に装着することができれば、どのようなものでも良い。たとえば、第１操作部材３１と押圧部４０とを別部材として形成し、固定ボルトを用いて両部材３１，４０を固定しても良い。
【００３９】
（ｄ）前記実施形態では、ねじ操作構造６において、第１および第２操作部材３１，３２がリアドラグ機構９の操作つまみとなる場合の例を示したが、操作部材は、前記実施形態に限定されず、リール本体１の機構を操作するものであれば、どのようなものでも良い。
図５は他の実施形態によるねじ操作構造を示している。このねじ操作構造においては、第３ねじ部材６３と、保持部材６４と、第３操作部材６５とが、両軸受リールのキャスティングコントロール機構の操作つまみとなっている。図５に示す両軸受リールのねじ操作構造は、リール本体のボディに設けられたねじ込み部６２と、第３ねじ部材６３と、保持部材６４と、第３操作部材６５とを備えている。ねじ込み部６２は、ボディに形成された雄ねじ部６６と、雄ねじ部６６と一体に形成される筒状部６７とを有している。第３ねじ部材６３には、ねじ込み部６２の雄ねじ部６６に螺合可能な雌ねじ部６８が設けられ、この雌ねじ部６８の内径より大径となるように、筒状部６７は形成されている。第３操作部材６５の円筒内周面上には凹部４２ｃが形成され、この凹部４２ｃの底部には規制部４３ｃが形成されている。この規制部４３ｃは、凹部４２ｃの底部から第３ねじ部材６３の中心に向けて突出した突起で構成されている。そして、第３操作部材６５は、筒状部６７側から第３ねじ部材６３の突出部７０に嵌合可能となっている。
【００４０】
このような両軸受リールのキャスティングコントロール機構の操作つまみであっても、ねじ込み部６２の雄ねじ部６６に第３ねじ部材６３を分割して装着でき、筒状部６７によって第３ねじ部材６３の抜け落ちが規制されるので、前記実施形態と同様な効果が得られる。

[Operation of reel body and screw operation structure]
When the yarn is to be unwound from the reel body 1, the bail 4 is moved down to the yarn releasing side. Then, when the fishing rod is cast, the fishing line is paid out from the spool 3. When winding the yarn, the bail 4 is returned to the yarn winding side. When the handle 10 is rotated in the line winding direction in this state, this rotational force is transmitted to the pinion gear 12 via the handle shaft 10a and the master gear 11. The torque transmitted to the pinion gear 12 causes the rotor 2 to rotate at the front of the pinion gear 12. On the other hand, the torque transmitted to the pinion gear 12 rotates the drive shaft 15 via an intermediate gear (not shown) that meshes with the pinion gear 12. At this time, the slider 16 meshing with the spiral groove of the drive shaft 15 is guided by the guide shaft 17 and moves in the front-rear direction. When the slider 16 moves, the spool shaft 14 and the spool 3 reciprocate in the front-rear direction together with the slider 16. By the rotation of the rotor 2 and the forward and backward movement of the spool 3, the fishing line guided from the bail 4 and the line roller 5 is uniformly wound around the outer periphery of the spool 3 in the forward and backward directions.
[0031]
The rear drag mechanism 9 is for adjusting the strength of the drag force on the spool 3 by rotating the first and second operation members 31 and 32. When the first operation member 31 at the rear of the reel body 1 is tightened, the pressing portion 40 formed integrally with the first operation member 31 moves forward, and the coil spring 21 connected to the pressing portion 40 is pushed. Then, the surfaces of the plurality of friction plates 19a of the first friction engagement portion 19 are close to each other, and the first flange portion 23 of the bush 18 is sandwiched by the plurality of friction plates 19a. As described above, when the first flange portion 23 of the bush 18 is pressed, the spool shaft 14 that cannot rotate with respect to the bush 18 also becomes difficult to rotate, and the drag force acting on the spool 3 increases. On the other hand, when the first operation member 31 is loosened, the pressing portion 40 moves rearward, and the pressed state of the coil spring 21 is gradually released. Then, the pressing of the first flange portion 23 by the friction plate 19a is released, and the spool shaft 14 that cannot rotate with respect to the bush 18 becomes easy to rotate, and the drag force acting on the spool 3 decreases.
[0032]
When the second operation member 32 is tightened, the second screw member 29 rotates together with the second operation member 32. Then, the pressing member 22 moves forward along the spool shaft 14 via the engaging portion 37 disposed between the second screw member 29 and the pressing member 22. Due to the movement of the pressing member 22, the surfaces of the plurality of friction plates 20a of the second friction engagement portion 20 come close to each other, and the second flange portion 24 of the bush 18 is sandwiched by the friction plates 20a. When the second flange portion 24 of the bush 18 is pressed in this way, the spool shaft 14 that cannot rotate with respect to the bush 18 also becomes difficult to rotate, and the drag force acting on the spool 3 increases. On the other hand, when the second operation member 32 is loosened, the pressing member 22 moves rearward along the spool shaft 14 and is pulled back in a direction away from the second friction engagement portion 20. Then, the pressing of the second flange portion 24 by the friction plate 20a is released, and the spool shaft 14 that cannot rotate with respect to the bush 18 becomes easy to rotate, and the drag force acting on the spool 3 decreases.
[0033]
[Assembly procedure of screw operation structure]

The screw operation structure of the dual-bearing reel shown in FIG. 5 includes a threaded portion 62 provided on the body of the reel body, a third screw member 63, a holding member 64, and a third operation member 65. The screwed portion 62 has a male screw portion 66 formed on the body and a cylindrical portion 67 formed integrally with the male screw portion 66. The third screw member 63 is provided with a female screw portion 68 that can be screwed to the male screw portion 66 of the screwed portion 62, and the cylindrical portion 67 is formed so as to have a diameter larger than the inner diameter of the female screw portion 68. . A concave portion 42c is formed on the inner peripheral surface of the cylinder of the third operation member 65, and a regulating portion 43c is formed at the bottom of the concave portion 42c. The restricting portion 43c is configured by a protrusion protruding from the bottom of the concave portion 42c toward the center of the third screw member 63. The third operation member 65 can be fitted to the projection 70 of the third screw member 63 from the cylindrical portion 67 side.
[0040]
Even with such an operation knob of the casting control mechanism of the dual-bearing reel, the third screw member 63 can be divided and mounted on the male screw portion 66 of the screwing portion 62, and the third screw member 63 falls off by the cylindrical portion 67. Is regulated, so that the same effect as in the above embodiment can be obtained.
(E) In the embodiment, the example in which the first operating member 31 is fixed to the first screw member 28 by the concave portion 42a and the restricting portion 43a has been described, but the method of fixing the first operating member 31 is as follows. The present invention is not limited to the embodiment, and the first operating member 31 may be fixed to the first screw member 28 by press-fitting or bonding. In the second and third operating members 32 and 65, after the second and third screw members 29 and 63 are elastically locked by the holding members 30 and 64, the second and third operating members 32 and 65 are , 42c and the restricting portions 43b, 43c have been described as examples in which the holding members 30 and 64 are fixed to the second and third screw members 29 and 63. Alternatively, the second and third operating members 32 and 65 may be press-fitted or adhered to the holding members 30 and 64 to the third screw members 29 and 63, and fixed.
[0041]
(F) In the above-described embodiment, the first to third operating members 31, 32, 65 are prevented from falling out of the first to third screw members 28, 29, 63 by the projections of the restricting portions 43a, 43b, 43c. Although an example of the case has been described, the shape of the restricting portions 43a, 43b, 43c is not limited to the above-described embodiment, and may be any shape as long as it can prevent escape.
[0042]
【The invention's effect】
According to the present invention, since the screw member is divided in the screw operation structure, the screw member can be easily mounted on the male screw portion. Further, since the diameter of the cylindrical portion of the screwed portion is larger than the inner diameter of the female screw portion, the falling off of the screw member or the operating member can be restricted by the cylindrical portion.
