Description

【０００１】
【発明の属する技術分野】
本発明は、リール本体、特に、釣竿に着脱自在に装着され、メインギアおよび螺軸を含む駆動機構が後方に配置されるスピニングリールのリール本体に関する。
【０００２】
【従来の技術】
従来のスピニングリールのリール本体は、釣竿に着脱自在に装着され、釣り糸を巻き取るために回転するロータと釣り糸を均一に巻き付けるために前後に往復移動するスプールとを駆動させるメインギアおよび螺軸を含む駆動機構が内部に配置されている。このようなリール本体は、本体部材と、竿取付脚部とを備えている。本体部材は、一般に、側面部と背面部とを有している。側面部は、駆動機構の側面を覆うように形成されている。背面部は、メインギアの後方と螺軸の後部とを覆うように、側面部と一体に形成されている。また、背面部は、螺軸の後部を覆うために、釣竿から離反する側に向けて傾斜をもって形成されている。竿取付脚部は本体部材の釣竿に接近する上部に設けられ、本体部材が竿取付脚部を介して釣竿に装着される（たとえば、特許文献１参照）。一方で、背面部の下部には、螺軸の外形に沿うように突出部が形成される場合もある（たとえば、特許文献２参照）。特に、リール本体が大型になるにつれて、リール本体後方への突出部が大きくなることが多い。

【発明が解決しようとする課題】
従来のスピニングリールのリール本体は、メインギアおよび螺軸を含む駆動機構が、本体部材の側面部と背面部とによって覆われるように形成されている。このとき、螺軸およびメインギアの両方を側面部と背面部とで覆うように本体部材を設計すると、リール本体の重量が重くなりやすい。これは、螺軸がメインギアよりも後方へと突出しているので、メインギアの後方と螺軸の上方とに駆動機構の存在しない空間を設けて、側面部と背面部とを形成せざるを得ないためである。そこで、駆動機構を必要最小限に覆うように本体部材の後部を設計しようとすると、メインギアより後方に突出した螺軸の後部を覆うように、側面部から後方に突出部を突出させて形成する必要がある。しかしながら、突出部を有するリール本体の場合、釣りを行っているときに糸ふけが生じたりすると、釣り糸が突出部に絡みつくおそれがある。
【０００６】
本発明の課題は、スピニングリールのリール本体において、リール本体の軽量化を図るとともに、リール本体に糸絡みしにくくすることにある。
【０００７】
【課題を解決するための手段】
発明１に係るスピニングリールのリール本体は、釣竿に着脱自在に装着され、釣り糸を巻き取るために回転するロータと釣り糸を均一に巻き付けるために前後に往復移動するスプールとを駆動させるメインギアおよび螺軸を含む駆動機構が内部に配置されるスピニングリールのリール本体であって、本体部材と、竿取付脚部と、ガード部材とを備えている。本体部材は、側面部と、背面部と、突出部とを有している。側面部は、駆動機構の側面を覆うように形成されている。背面部は、側面部に一体に形成され、メインギアの後方を覆うように形成されている。突出部は、背面部の釣竿から離反する下部に形成され、螺軸の外形に沿うように側面部から後方に突出して形成されている。竿取付脚部は、本体部材の釣竿に接近する上部に設けられている。ガード部材は、背面部の後方と突出部の上方とに空間を設けて本体部材に装着されている。
【０００８】
このスピニングリールのリール本体では、本体部材が竿取付脚部において釣竿に装着される。本体部材の側面部は駆動機構の側面に、背面部はメインギアの後方に配置される。突出部は、螺軸の外形に沿うように側面部から後方に突出して形成される。そして、ガード部材が、背面部の後方と突出部の上方とに空間を設けて本体部材に装着される。
【０００９】
ここでは、本体部材が、側面部と背面部と突出部とで駆動機構を覆うことができるように必要最小限に設計されているので、本体部材の軽量化を図ることができる。また、本体部材の背面部の後方と突出部の上方とに空間を設けて、ガード部材が本体部材に装着されているので、釣りを行っているときに糸ふけが生じても、リール本体に糸絡みしにくくなる。一方で、ガード部材は本体部材のように駆動機構を保護する必要がないので、ガード部材は、本体部材ほど強度や剛性を高くしなくても、ガード部材の役割を果たすことができる。そこで、ガード部材の部材厚等を薄くしたり、ガード部材に比重の小さい材質を用いたりして、ガード部材の軽量化を図れば、ガード部材の自重を減少させることができ、本体部材にガード部材を装着してもリール本体全体での重量を小さく抑えることができる。なお、ガード部材は、本体部材との間に空間を設けて本体部材に装着されているので、ガード部材の外観は自由にデザインすることができ、リール本体全体のシルエットも変化に富んだものにすることができる。
【００１０】
発明２に係るスピニングリールのリール本体は、発明１に記載のスピニングリールのリール本体において、ガード部材が、本体部材の外形に少なくとも一部を接触させるように曲率をもって形成されている。この場合、ガード部材が、本体部材の外形に少なくとも一部を接触させるように曲率をもって形成されているので、リール本体全体のシルエットに変化を持たせながら、無駄のないガード部材を形成することができ、ガード部材の軽量化を図ることができる。
【００１１】
発明３に係るスピニングリールのリール本体は、発明１又は２に記載のスピニングリールのリール本体において、ガード部材が、複数の棒部材によって構成される骨組み構造体となっている。この場合、ガード部材が骨組み構造体となっているので、リール本体への糸絡みを防止することができるとともに、ガード部材の強度および剛性を骨組み構造で確保することができる。また、骨組み構造体は複数の棒部材によって構成されているので、ガード部材のさらなる軽量化を図ることができる。
【００１２】
発明４に係るスピニングリールのリール本体は、発明３に記載のスピニングリールのリール本体において、ガード部材が、骨組み構造体に装着されるカバー部材をさらに有している。この場合、骨組み構造体にはカバー部材が装着されているので、リール本体への糸絡みを効果的に防止することができるとともに、ガード部材の外観に対する要求にも柔軟に対応することができる。
【００１３】
発明５に係るスピニングリールのリール本体は、発明４に記載のスピニングリールのリール本体において、骨組み構造体とカバー部材とは一体に形成されている。この場合、骨組み構造体とカバー部材とは一体に形成されているので、ガード部材の強度および剛性をさらに向上することができる。
発明６に係るスピニングリールのリール本体は、発明１又は２に記載のスピニングリールのリール本体において、ガード部材が、一体の面部材によって形成される曲面構造体となっている。この場合、ガード部材が曲面構造体となっているので、リール本体への糸絡みを防止することができるとともに、ガード部材の強度および剛性は曲面構造で確保することができる。
【００１４】
発明７に係るスピニングリールのリール本体は、発明６に記載のスピニングリールのリール本体において、曲面構造体には、複数のリブが面部材の内面に沿うように一体に形成されている。この場合、曲面構造体には複数のリブが面部材の内面に沿うように一体に形成されているので、ガード部材の面外剛性を向上することができ、ガード部材に面外変形を生じにくくすることができる。
【００１５】
発明８に係るスピニングリールのリール本体は、発明１から７のいずれかに記載のスピニングリールのリール本体において、本体部材とガード部材との間に設けられた空間内で、本体部材には第１ボス部が本体部材から外方に突出して一体に形成されており、第１ボス部に連結可能な第２ボス部がガード部材の内面に一体に形成されている。この場合、本体部材に形成された第１ボス部とガード部材に形成された第２ボス部とが連結可能となっているので、ガード部材の面外変形を抑制することができる。たとえば、ガード部材が外力を受けるような場合、第１および第２ボス部によって外力に対する変形に抵抗することができる。また、第１ボス部と第２ボス部とは、本体部材とガード部材との間に設けられた空間内に形成されているので、第１および第２ボス部を形成したとしても、ガード部材の外観を損なうことがない。
【００１６】
発明９に係るスピニングリールのリール本体は、発明８に記載のスピニングリールのリール本体において、第１ボス部および第２ボス部の端部には、いずれか一方に凸部が形成され、いずれか他方に凹部が形成され、凸部と凹部とが嵌合して互いに連結されている。この場合、第１ボス部および第２ボス部の端部において、凸部と凹部とが嵌合して互いに連結されているので、第１ボス部と第２ボス部とを容易に位置決めして連結することができる。
【００１７】
発明１０に係るスピニングリールのリール本体は、発明８又は９に記載のスピニングリールのリール本体において、ガード部材の第２ボス部が、本体部材の第１ボス部にガード部材の外側からねじ止めされている。この場合、ガード部材の第２ボス部が本体部材の第１ボス部にガード部材の外側からねじ止めされているので、第１ボス部と第２ボス部とを確実に連結することができ、両ボス部材を介して本体部材とガード部材と一体化することができる。
【００１８】
発明１１に係るスピニングリールのリール本体は、発明１から１０のいずれかに記載のスピニングリールのリール本体において、本体部材には、本体部材とガード部材との間に設けられた空間側から駆動機構側に向けて、本体部材の少なくとも一部を貫通した軽量孔が設けられている。この場合、本体部材には、本体部材とガード部材との間に設けられた空間側から駆動機構側に向けて、本体部材の少なくとも一部を貫通した軽量孔が設けられているので、本体部材のさらなる軽量化を図ることができる。
【００１９】
発明１２に係るスピニングリールのリール本体は、発明１から１１のいずれかに記載のスピニングリールのリール本体において、ガード部材が、本体部材にねじ止めされている。この場合、ガード部材が本体部材にねじ止めされているので、ガード部材を本体部材に確実に固定することができる。
発明１３に係るスピニングリールのリール本体は、発明１から１２のいずれかに記載のスピニングリールのリール本体において、ガード部材が、合成樹脂製となっている。この場合、ガード部材が合成樹脂製となっているので、ガード部材の軽量化を図ることができるとともに、ガード部材を任意形状に容易に形成することができる
発明１４に係るスピニングリールのリール本体は、発明１から１２のいずれかに記載のスピニングリールのリール本体において、ガード部材が、金属製となっている。この場合、ガード部材が金属製となっているので、ガード部材を任意形状に形成することができるだけでなく、ガード部材の強度および剛性も同時に確保することができる。
【００２０】
発明１５に係るスピニングリールのリール本体は、発明５に記載のスピニングリールのリール本体において、骨組み構造体とカバー部材とはそれぞれが金属と合成樹脂とで形成され、骨組み構造体がカバー部材にインサート成型されている。この場合、骨組み構造体とカバー部材とはそれぞれが金属と合成樹脂とで形成されているので、ガード部材の強度および剛性は骨組み構造体によって確保でき、ガード部材の外観はカバー部材によって任意に形成することができる。また、骨組み構造体がカバー部材にインサート成型されているので、骨組み構造体とカバー部材とは、材質が異なっていても容易に一体成型することができる。
【００２１】
【発明の実施の形態】
〔第１実施形態〕
〔スピニングリールの構成〕
スピニングリールは、図１および図２に示すように、ハンドル１と、ハンドル１を回転自在に支持するリール本体２と、釣り糸を巻き取るために回転するロータ３と、釣り糸を均一に巻き付けるために前後に往復移動するスプール４とを備えている。図１ではハンドル１がリール本体２の左側に装着され、図２ではハンドル１が右側に装着されている。このように、ハンドル１はリール本体２の左右いずれにも装着可能である。
【００２２】
リール本体２は、図１から図３に示すように、本体部材２０と、ガード部材２２と、竿取付脚部２３とを備えている。本体部材２０は、本体部材２０の釣竿に接近する上部に設けられた竿取付脚部２３において、釣竿に装着されている。本体部材２０は、たとえばアルミニウム合金製の部材であり、リールボディ２０ａと蓋部材２０ｂとを有している。リールボディ２０ａには、内部空間が形成されており、この内部空間にメインギア１１および螺軸１９を含む駆動機構が配置される。リールボディ２０ａは、側面部２５と、背面部２６と、突出部２７とを有している。側面部２５は、駆動機構の側面を覆うように形成されている。背面部２６は、側面部２５に一体に形成され、メインギア１１の後方を覆うように設けられている。また、背面部２６は、釣竿から離反する側に向けて傾斜をもって形成されている。この背面部２６には、第１ボス部２６ａが本体部材２０から外方に突出して一体に形成されている。第１ボス部２６ａの端部には、凸部２６ｂが形成されている（図４参照）。突出部２７は、背面部２６の釣竿から離反する下部に形成され、螺軸１９の外形に沿うように側面部２５から後方に突出して形成されている。また、リールボディ２０ａの前端には、円形の第１フランジ部２ｄと、第１フランジ部２ｄより小径で先端が開口する円筒部２ｅとが形成されている。円筒部２ｅの外周面には凹状溝２ｆが設けられている。この凹状溝２ｆは、片側面が第１フランジ部２ｄの前面と同一面となるように配置されている。第１フランジ部２ｄは、一部分が欠落した略半円形状に形成されている。さらに、リールボディ２０ａの内部空間には、ロータ３をハンドル１の回転に連動して回転させるロータ駆動機構５と、スプール４を前後に移動させて釣り糸を均一に巻き取るためのオシレーティング機構６とが装着されている。
【００２３】
蓋部材２０ｂは、たとえばアルミニウム合金製の部材であり、図３に示すように、リールボディ２０ａの側面部２５と略対称な鏡像関係の形状に形成されている。蓋部材２０ｂの前端部には、第２フランジ部２ｇが一体形成されている。この第２フランジ部２ｇを第１フランジ部２ｄの欠落部分に配置するようにして、蓋部材２０ｂはリールボディ２０ａにねじ止めされる。この状態では、第１および第２フランジ部２ｄ，２ｇの前面と、円筒部２ｅに形成された凹状溝２ｆの片側面とは同一面になっている。凹状溝２ｆにはシール部材２９が嵌合可能になっており、シール部材２９が第１および第２フランジ部２ｄ，２ｇの前面に当接している。シール部材２９は、たとえばＯリングになっており、このＯリングによって第１および第２フランジ部２ｄ，２ｇの前面をシールしている。
【００２４】
ガード部材２２は、たとえば合成樹脂製であり、図２から図４に示すように、本体部材２０の外形に少なくとも一部を接触させるように曲率をもった面部材によって形成されている。このガード部材２２は、竿取付脚部２３の下方で、背面部２６の後方と突出部２７の上方とに空間Ｓ１を設けて、本体部材２０に装着させている。このとき、ガード部材２２は、背面部２６上部と突出部２７下面とで本体部材２０に接触しており、本体部材２０に着脱自在にねじ止めされる。また、ガード部材２２と本体部材２０との間には、スペーサ２４が介装されている。このスペーサ２４は、たとえば合成樹脂製であり、ガード部材２２と本体部材２０との隙間を埋めている。ガード部材２２の内面には第２ボス部２２ａが一体に形成されている。第２ボス部２２ａの端部には凹部２２ｂが形成されている。この第２ボス部２２ａの凹部２２ｂを第１ボス部２６ａの凸部２６ｂに嵌合することで、第１ボス部２６ａと第２ボス部２２ａとは互いに連結される。
【００２５】
ロータ３は、図２に示すように、リール本体２の前部に回転自在に支持されている。ロータ３は、ロータ円筒部３０と、第１ロータアーム３１および第２ロータアーム３２とを有している。第１および第２ロータアーム３１，３２は、ロータ円筒部３０の側方に互いに対向して設けられている。ロータ円筒部３０と第１および第２ロータアーム３１，３２とは、たとえばアルミニウム合金製であり、互いが一体に成形されている。ロータ円筒部３０の前部には前壁３３が形成されており、前壁３３の中央部にはボス部３３ａが形成されている。ボス部３３ａの中心部には貫通孔が形成されており、この貫通孔をピニオンギアの前部及びスプール軸１５が貫通している。前壁３３の前部にロータ３の固定用のナット１３が配置されている。
【００２６】
第１および第２ロータアーム３１，３２は、ロータ円筒部３０の周面上で周方向に広がりをもたせて接続させており、ロータ円筒部３０から外方に突出して湾曲しながら前方に延びている。第１ロータアーム３１は、先端に第１ベール支持部材４０が揺動自在に装着されている。そして、第１ベール支持部材４０の先端には、釣り糸をスプール４に案内するためのラインローラ４１が装着されている。第２ロータアーム３２は、先端に第２ベール支持部材４２が揺動自在に装着されている。ラインローラ４１と第２ベール支持部材４２との間には、線材を略Ｕ状に湾曲させた形状のベール４３が固定されている。このように、第１ベール支持部材４０および第２ベール支持部材４２、ラインローラ４１、ベール４３によって、釣り糸をスプール４に案内するベールアーム４４が構成される。
【００２７】
ロータ駆動機構５は、図２に示すように、ハンドル１が回転不能に装着されたハンドル軸１０と、ハンドル軸１０とともに回転するメインギア１１と、メインギア１１に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３の中心部を貫通しており、ナット１３によりロータ３に固定されている。ピニオンギア１２は、その軸方向の中間部と後端部とが、それぞれ軸受１４ａ、１４ｂを介してリール本体２に回転自在に支持されている。
【００２８】
スプール４は、図２に示すように、釣り糸を外周面に巻き取るものであり、ロータ３の第１ロータアーム３１と第２ロータアーム３２との間に、ロータ３の前部で前後移動自在に配置されている。このスプール４は、ドラグ機構７１を介してスプール軸１５の先端に連結されている。スプール４は、外周に釣り糸が巻かれる糸巻胴部４ａと、糸巻胴部４ａの後部に一体で形成されたスカート部４ｂと、糸巻胴部４ａの前端に一体で形成されたフランジ部４ｃとを有している。
【００２９】
オシレーティング機構６は、図２に示すように、スプール軸１５を前後方向に移動させて、スプール４を同方向に移動させるための機構である。オシレーティング機構６は、スプール軸１５の下方に平行に配置された螺軸１９と、螺軸１９に沿って前後方向に移動するスライダ１７と、螺軸１９の先端に固定された中間ギア１８とを有している。スライダ１７は、スプール軸１５の後端に回転不能に固定されている。中間ギア１８は、図示しない減速機構を介してピニオンギア１２に噛み合っている。
【００３０】
このように構成されるスピニングリールでは、本体部材２０が、側面部２５と背面部２６と突出部２７とで駆動機構を覆うことができるように必要最小限に設計されているので、本体部材２０の軽量化を図ることができる。また、本体部材２０の背面部２６の後方と突出部２７の上方とに空間Ｓ１を設けて、ガード部材２２が本体部材２０に装着されているので、釣りを行っているときに糸ふけが生じても、リール本体２に糸絡みしにくくなる。さらに、本体部材２０とガード部材２２との間に設けられた空間Ｓ１内で、本体部材２０に形成された第１ボス部２６ａとガード部材２２に形成された第２ボス部２２ａとが連結可能となっているので、ガード部材２２の面外変形を拘束することができる。
【００３１】
一方で、ガード部材２２は、本体部材２０のように駆動機構を保護する必要がないので、ガード部材２２は、本体部材２０ほど強度や剛性を高くしなくても、ガード部材２２の役割を果たすことができる。そこで、ガード部材２２の部材厚等を薄くしたり、ガード部材２２に比重の小さい材質を用いたりして、ガード部材２２の軽量化を図れば、ガード部材２２の自重を減少させることができ、本体部材２０にガード部材２２を装着してもリール本体２全体での重量を小さく抑えることができる。なお、ガード部材２２は、本体部材２０との間に空間Ｓ１を設けて本体部材２０に装着されているので、ガード部材２２の外観は自由にデザインすることができ、リール本体２全体のシルエットも変化に富んだものにすることができる。
【００３２】
〔第２実施形態〕
〔スピニングリールの構成〕
スピニングリールは、図５に示すように、ハンドル１０１と、ハンドル１０１を回転自在に支持するリール本体１０２と、釣り糸を巻き取るために回転するロータ１０３と、釣り糸を均一に巻き付けるために前後に往復移動するスプール１０４とを備えている。この第２実施形態では、リール本体１０２を除いた構成は第１実施形態の構成と同一のため、同一部分の構成については説明を省略する。また、リール本体１０２は、本体部材１２０と、ガード部材１２２と、竿取付脚部１２３とを有しているが、本体部材１２０と竿取付脚部１２３とは第１実施形態の構成と同一の構成であるため、第２実施形態ではガード部材１２２についての説明を行うものとする。
【００３３】
ガード部材１２２は、第１実施形態と同様に、竿取付脚部１２３の下方で背面部１２６の後方と突出部１２７の上方とに空間を設けて形成されている。このガード部材１２２は、図６に示すように、骨組み構造体１２５とカバー部材１２８とを有している。骨組み構造体１２５は、たとえば金属製であり、本体部材１２０の外形に少なくとも一部を接触させるように曲率をもった複数の棒部材１２５ａによって構成されている。この骨組み構造体１２５の外側には、カバー部材１２８が装着されている。カバー部材１２８は、たとえば合成樹脂製であり、骨組み構造体１２５の外形に沿うように形成されている。このような骨組み構造体１２５とカバー部材１２８とは、本体部材１２０の背面部１２６上部と突出部１２７下面とで本体部材１２０に接触しており、この位置で本体部材１２０にねじ止めされる。
【００３４】
このように構成されるスピニングリールでは、第１実施形態と同様に、本体部材１２０が、側面部（図示しない）と背面部１２６と突出部１２７とで駆動機構を覆うことができるように必要最小限に設計されているので、本体部材１２０の軽量化を図ることができる。ガード部材１２２は、骨組み構造体１２５とカバー部材１２８とで構成されており、本体部材１２０の背面部１２６の後方と突出部１２７の上方とに空間を設けて本体部材１２０に装着されているので、釣りを行っているときに糸ふけが生じても、リール本体１０２に糸絡みしにくくなる。骨組み構造体１２５は、複数の棒部材１２５ａによって構成されているので、カバー部材１２８の軽量化を図ることができる。また、骨組み構造体１２５にカバー部材１２８を装着することで、リール本体１０２への糸絡みを効果的に防止することができるとともに、ガード部材１２２の外観に対する要求に柔軟に対応することができる。
【００３５】
一方で、ガード部材１２２は、本体部材１２０のように駆動機構を保護する必要がないので、ガード部材１２２は、本体部材１２０ほど強度や剛性を高くしなくても、ガード部材１２２の役割を果たすことができる。たとえば、ガード部材１２２の強度および剛性を骨組み構造体１２５で確保することができるように設計しておけば、カバー部材１２８の部材厚等を薄くしたり、カバー部材１２８に比重の小さい材質を用いたりして、骨組み構造体１２５とカバー部材１２８とで構成されたガード部材１２２の自重を減少させることができる。すると、本体部材１２０にガード部材１２２を装着してもリール本体１０２全体での重量を小さく抑えることができる。また、カバー部材１２８の外観に変化を持たせると、リール本体１０２全体のシルエットも変化に富んだものにすることができる。
【００３６】
〔他の実施形態〕
（ａ）前記第１実施形態では、ガード部材２２を合成樹脂製にした場合の例を示したが、ガード部材２２の材質は、前記実施形態に限定されず、ガード部材２２として必要となる強度と剛性を確保することができれば、どのようなものでも良い。たとえば、ガード部材２２を金属製にした場合にも本発明は適用できる。
【００３７】
（ｂ）前記第１実施形態では、ガード部材２２の第２ボス部２２ａを本体部材２０の第１ボス部２６ａに嵌合して連結した場合の例を示したが、第１ボス部２６ａと第２ボス部２２ａとの連結方法は、前記実施形態に限定されず、第１ボス部２６ａと第２ボス部２２ａとを連結した状態で、ガード部材２２の外側から第２ボス部２２ａを第１ボス部２６ａに連結してねじ止めしても良い。
【００３８】
（ｃ）前記第１実施形態では、ガード部材２２を本体部材２０に直接装着するだけでなく、ガード部材２２の第２ボス部２２ａを本体部材２０の第１ボス部２６ａに連結させた場合の例を示したが、ガード部材２２の強度と剛性を確保した上でガード部材２２を本体部材２０に固定できれば、必ずしも第１および第２ボス部２２ａを設ける必要はない。
【００３９】
（ｄ）前記第１実施形態では、ガード部材２２が曲率をもたせた面部材によって形成される場合の例を示したが、ガード部材２２の構造は、前記実施形態に限定されず、ガード部材２２の剛性を向上することができるならば、どのようなものにしても良い。たとえば、図７に示すように、ガード部材２２において、複数のリブ１３０を面部材の内面に沿うように一体に形成しても良い。これにより、ガード部材２２の面外剛性を向上することができ、ガード部材２２の面外変形を生じにくくすることができる。
【００４０】
（ｅ）前記第２実施形態では、骨組み構造体１２５を金属製にしてカバー部材１２８を合成樹脂製にした場合の例を示したが、骨組み構造体１２５およびカバー部材１２８の材質は、前記実施形態に限定されず、ガード部材１２２として必要となる強度と剛性を確保することができれば、どのようなものでも良い。たとえば、骨組み構造体１２５およびカバー部材１２８の材質を、互いに金属製にしたり合成樹脂製にしたりしても良い。
【００４１】
（ｆ）前記第２実施形態では、骨組み構造体１２５にカバー部材１２８を装着してガード部材１２２を形成する場合の例を示したが、ガード部材１２２の形成方法は、前記実施形態に限定されず、ガード部材１２２として必要となる強度と剛性を確保することができれば、どのようにしても良い。たとえば、骨組み構造体１２５をカバー部材１２８にインサート成型して、ガード部材１２２を一体に成型しても良い。また、カバー部材１２８を用いることなく、骨組み構造体１２５だけでガード部材１２２を構成しても良い。
【００４２】
（ｇ）前記第１および第２実施形態では、本体部材２０，１２０とガード部材２６，１２２との間に設けられた空間内の本体部材２０，１２０が面状に形成されている場合の例を示したが、空間内の本体部材２０，１２０は、前記実施形態に限定されず、本体部材２０，１２０の強度および剛性を確保することができれば、どのようにしても良い。たとえば、空間内の本体部材２０，１２０に、空間側から駆動機構側に向けて軽量孔を設けると、本体部材２０，１２０のさらなる軽量化を図ることができる。

[Problems to be solved by the invention]
The reel body of a conventional spinning reel is formed such that a drive mechanism including a main gear and a screw shaft is covered by a side surface portion and a back surface portion of a main body member. At this time, if the main body member is designed so as to cover both the screw shaft and the main gear with the side surface portion and the back surface portion, the weight of the reel main body tends to increase. This is because the screw shaft protrudes rearward from the main gear, so there is a need to provide a space without a drive mechanism behind the main gear and above the screw shaft to form the side surface and the back surface. It is because it cannot be obtained. Therefore, when trying to design the rear part of the main body member so as to cover the drive mechanism to the minimum necessary, it is formed by projecting the projection part rearward from the side part so as to cover the rear part of the screw shaft projecting rearward from the main gear. There is a need to. However, in the case of a reel body having a protruding portion, if line dangling occurs during fishing, the fishing line may be entangled with the protruding portion.

In the spinning reel configured as described above, similarly to the first embodiment, the main body member 120 is required to be able to cover the driving mechanism with the side surface (not shown), the back surface 126, and the protrusion 127. Since the main body member 120 is designed to be limited in size, the weight of the main body member 120 can be reduced. The guard member 122 is composed of a skeleton structure 125 and a cover member 128, and is attached to the main body member 120 with a space provided behind the back surface 126 of the main body member 120 and above the protrusion 127. In addition, even if line dangling occurs during fishing, the line is less likely to become entangled with the reel body 102. Since the frame structure 125 is composed of the plurality of rod members 125a, the weight of the cover member 128 can be reduced. In addition, by attaching the cover member 128 to the frame structure 125, the thread entanglement with the reel body 102 can be effectively prevented, and the requirement for the appearance of the guard member 122 can be flexibly accommodated.
[0035]
On the other hand, since the guard member 122 does not need to protect the drive mechanism unlike the main body member 120, the guard member 122 plays the role of the guard member 122 without increasing the strength and rigidity as much as the main body member 120. be able to. For example, if the strength and rigidity of the guard member 122 are designed so as to be ensured by the frame structure 125, the cover member 128 can be made thinner or a material having a small specific gravity can be used for the cover member 128. As a result, the weight of the guard member 122 composed of the frame structure 125 and the cover member 128 can be reduced. Then, even if the guard member 122 is attached to the main body member 120, the weight of the entire reel main body 102 can be reduced. Further, when the appearance of the cover member 128 is changed, the silhouette of the entire reel body 102 can be varied.

【The invention's effect】
According to the present invention, in the reel body of the spinning reel, the main body member is designed to be the minimum necessary so that the drive mechanism can be covered by the side surface portion, the back surface portion, and the projecting portion. Can be achieved. In addition, a space is provided behind the rear part of the main body member and above the protruding part, and the guard member is attached to the main body member. It becomes difficult to entangle the thread. On the other hand, since the guard member does not need to protect the drive mechanism unlike the main body member, the guard member can play the role of the guard member without increasing the strength and rigidity of the main body member. Therefore, if the weight of the guard member is reduced by reducing the thickness or the like of the guard member or by using a material having a small specific gravity for the guard member, the weight of the guard member can be reduced, and the guard member can be attached to the main body member. Even if a member is mounted, the weight of the entire reel body can be reduced. In addition, since the guard member is provided with a space between the main body member and the main body member, the appearance of the guard member can be freely designed, and the silhouette of the entire reel body is also varied. can do.
