Description

【０００１】
【発明の属する技術分野】
本発明は、一方向クラッチを用いた魚釣用リールの逆転防止装置に関する。
【０００２】
【従来の技術】
今日、スピニングリールを始め、電動リールや両軸受型リールといった多くの魚釣用リールに、一方向クラッチを用いた逆転防止装置が装着されている。
図３は実用新案登録第２５２４４７７号公報に開示されたスピニングリールを示し、図中、１は軸受３を介してリール本体５に回転可能に支持された中空なフライヤ軸（回転体）で、その先端側外周にロータ７がナット９で固定されている。そして、フライヤ軸１の後端側外周に刻設されたピニオンに、ハンドル軸に固着した駆動歯車が噛合しており、ハンドル１１の巻取り操作でロータ７が釣糸巻取り方向（正転方向）へ回転するようになっている。
【０００３】
そして、ロータ７には一対の支持アーム１３が形成されており、両支持アーム１３の先端に、ラインローラ１５を装着したベールアーム１７とベールホルダー１９を介して半環状のベール２１が、釣糸巻取位置と釣糸放出位置へ反転自在に取り付けられている。
【０００４】
また、図中、２３はフライヤ軸１を挿通するスプール軸で、当該スプール軸２３のロータ側突出端にスプール２５が取り付けられている。そして、スプール軸２３の後端側にトラバース機構が装着されており、ベール２１を釣糸巻取位置側へ倒してハンドル操作でロータ７を釣糸巻取り方向へ回転させると、トラバース機構によって前後方向へトラバース運動するスプール２５に釣糸が巻回され、ベール２１を釣糸放出位置側へ反転させて仕掛けをキャスティングすると、スプール２５に巻回された釣糸がスパイラル状に繰り出されるようになっている。
【０００５】
そして、このスピニングリール２７は、ロータ７の円筒部２９の内部に、キャスティング時や釣糸の巻取り時にロータ７の釣糸繰出し方向（逆転方向）への回転を防止する逆転防止装置３１が装着されている。
図４及び図５は逆転防止装置３１の詳細を示し、この逆転防止装置３１は、フライヤ軸１の外周に装着された一方向クラッチ３３と、当該一方向クラッチ３３の外周に嵌合固定された筒状の逆転防止体３５と、当該逆転防止体３５の外周に形成されたラチェット３７の係止部６９に係止可能な係止爪３９とで構成されており、各ラチェット３７間には、係止爪３９の抜止めを図る切欠部３８が形成されている。
【０００６】
而して、一方向クラッチ３３は、図５に示すようにフライヤ軸１の外周に固着された内輪４１と、上記逆転防止体３５が外周に取り付く外輪４３と、内，外輪４１，４３間に配置された複数のコロ４５とスペーサ４７，バネ４９で構成されており、内輪４１は外周が円形に形成され、コロ４５はスペーサ４７によって等間隔に保持されている。そして、外輪４３の周壁に、各コロ４５に対応して凹部（非楔領域）５１とこれに連続する傾斜面（楔領域）５３が形成されており、コロ４５は夫々バネ４９によって傾斜面５３方向に付勢されている。
【０００７】
一方、係止爪３９は図４に示すように平面視く字形状に形成されて、上記切欠部３８に係合可能な係合部５５が爪先に形成されている。そして、係止爪３９はリール本体５に回転可能に支持されて、バネ部材５７によって係止部６９との係止方向に常時付勢されている。
【０００８】
そして、係止爪３９は、操作杆５９の先端に設けたカム６１によって係止部６９に係脱可能に制御され、操作杆５９のバネ掛部６３とリール本体５との間にトーションバネ６５が架設されている。そして、図３に示すようにリール本体５の後方に突出した操作杆５９にツマミ６７が取り付けられており、当該ツマミ６７を図４のＯＮ方向に操作すると、実線で示すように切欠部３８に係合部５５が係合し乍ら係止爪３９が係止部６９に係止し、また、ツマミ６７をＯＦＦ（逆転可能状態）方向に操作すると、二点鎖線で示すようにカム６１がバネ部材５７に抗して係止爪３９を反時計方向に回動させて、係止部６９との係止状態を解除させるようになっている。
【０００９】
実用新案登録第２５２４４７７号公報に開示された逆転防止装置３１はこのように構成されており、釣人がツマミ６７をＯＮ方向に操作した状態（逆転防止状態）でハンドル１１を巻取り操作すると、フライヤ軸１の正転に伴いコロ４５が回転し乍ら凹部５１に移動するため、フライヤ軸１（ロータ７）は釣糸巻取り方向に支障なく回転する。
【００１０】
そして、斯かる逆転防止状態に於て、魚の引きで釣糸が繰り出されてロータ７が逆方向に回転してフライヤ軸１が同方向に回転すると、コロ４５が傾斜面５３方向に移動して内，外輪４１，４３間に食い込み、その楔作用でフライヤ軸１と逆転防止体３５が一方向クラッチ３３を介して一体となるため、係合部５５が切欠部３８に係合し乍ら、係止爪３９が係止部６９に係止してロータ７の釣糸繰出し方向への回転が阻止される。
【００１１】
また、既述したようにツマミ６７をＯＦＦ方向に操作すると、係止爪３９と係止部６９との係止状態が解除されるため、逆転防止機構３１が逆転可能状態に切り換わってロータ７が正逆両方向へ回転可能となる。
【００１２】
このように逆転防止装置３１は、一方向クラッチ３３を介してフライヤ軸１に連結した逆転防止体３５のラチェット３７に係止爪３９を係脱させることで、逆転防止状態と逆転可能状態に切り換わるように構成されているが、図５に示すようにラチェット３７の形状は、フライヤ軸１の逆転時に係止爪３９が確実に係止するように逆転防止用の係止部６９が、これに対向するラチェット３７の壁面７１より径方向外方に高く形成されていた。
【００１３】
【発明が解決しようとする課題】
ところで、既述したようにツマミ６７をＯＦＦ方向に操作すると、係止爪３９と係止部６９との係止状態が解除されるため、逆転防止機構３１が逆転可能状態に切り換わってロータ７が正逆両方向へ回転可能となるが、釣糸の巻取り操作に伴い、コロ４５と内，外輪４１，４３との摩擦で逆転防止体３５は正転方向へロータ７と供回りする。
【００１４】
このため、逆転可能状態での急激，高速な巻取り操作中に、ツマミ６７を操作して逆転防止装置３１を逆転防止状態に切り換えても、係止爪３９が係止部６９に係止せずにラチェット３７に乗り上がって逆転防止体３５が空転してしまう虞があり、この結果、瞬時のロータ７の逆転防止ができず、また、係止爪３９が衝接しての逆転防止体３５の空転により係止爪３９やラチェット３７が摩耗，損傷して、逆転防止機能に支障を来してしまう等の課題が残されていた。
【００１５】
本発明は斯かる実情に鑑み案出されたもので、 一方向クラッチを用いたこの種の逆転防止装置に改良を加え、不必要な逆転防止体の空転防止を図って、実釣時の逆転防止機能の向上を図った魚釣用リールの逆転防止装置を提供することを目的とする。
【００１６】
【課題を解決するための手段】
斯かる目的を達成するため、請求項１に係る発明は、ハンドル操作に連動回転する回転体に一方向クラッチを介して逆転防止体を連結し、リール本体に、前記逆転防止体の外周に形成したラチェットの逆転防止用の係止部に係脱可能な係止爪を装着した魚釣用リールの逆転防止装置に於て、前記係止部を、ラチェットの周方向の一端側に形成され、逆転防止体の逆転時に前記係止爪が係止可能な逆転用係止部と、ラチェットの周方向の他端側に、前記逆転用係止部と略同一またはそれ以上の寸法で径方向外方へ突設され、逆転防止装置の逆転可能状態から逆転防止状態への切換え時に前記逆転防止体が正転方向へ高速で回転していても、前記係止爪がラチェットに乗り上がることなく切換えと同時に係止する正転用係止部とで構成すると共に、各逆転用係止部と正転用係止部とに隣接した逆転防止体の外周に、前記係止爪が係止して係止爪の抜止めを図る凹状の切欠部を周方向に離間して設けたことを特徴とする。
【００１７】
（作用）
請求項１に係る発明によれば、逆転可能状態での高速な巻取り操作中に逆転防止装置を逆転可能状態から逆転防止状態に切り換え操作すると、係止爪がラチェットに乗り上がることなく切換えと同時に正転用係止部に係止してロータの逆転防止状態に速やかに移行し、切り換え操作時の不要な回転方向の空転が防止されることとなる。
【００１８】
【発明の実施の形態】
以下、本発明の実施形態を図面に基づき説明する。
【００１９】
尚、発明部分を除く逆転防止装置の構成は図３以下に示す従来例と同様であるため、ここではそれらについての説明は省略し、専ら発明部分について説明し、上記従来例と同一のものは同一符号を以って表示する。
図１は請求項１に係る逆転防止装置に用いる逆転防止体の第一実施形態を示し、本実施形態に於ける逆転防止体７３も、既述した逆転防止体３５と同様、筒状に成形されて一方向クラッチ３３の外輪４３の外周に固着されている。
【００２０】
そして、図示するようにその外周に、平面視円弧状のラチェット７５が周方向へ等間隔に４個形成されており、従来と同様、各ラチェット７５の周方向の一端側に、逆転防止体７３の逆転時に係止爪３９が瞬時に係止可能な逆転用係止部７７が形成されているが、本実施形態は、斯かる構成に加え、各ラチェット７５の周方向の他端側に、逆転防止装置の逆転可能状態から逆転防止状態への切換え時に、逆転防止体７３が正転方向へ高速で回転していても、係止爪３９がラチェット７５に乗り上がることなく切換えと同時に係止可能な正転用係止部７９を、上記逆転用係止部７７と略同一またはそれ以上の寸法で径方向外方へ突設したことを特徴とする。
【００２１】
而して、上述の如き構成により、図１に示すように逆転防止体７３の中心Ｏから正転用係止部７９の突出端Ｐまでの寸法Ｌ１と、逆転防止体７３の中心Ｏから逆転用係止部７７の突出端Ｑまでの寸法Ｌ２はＬ１≧Ｌ２の関係になっている。
そして、本実施形態は更に、各逆転用係止部７７と正転用係止部７９とに隣接した逆転防止体７３の外周に、図３の従来例と同様、係止爪３９が係止して係止爪３９の抜止めを図る凹状の切欠部８１を周方向に離間して設けたものである。
【００２２】
本実施形態に係る逆転防止装置の逆転防止体７３はこのように構成されているから、実釣に当たり釣人がツマミ６７をＯＮ方向に操作すると、係合部５５が切欠部８１に係合して係止爪３９が逆転用係止部７７に係止する。そして、この状態でハンドル１１を巻取り操作すると、フライヤ軸１の正転に伴いコロ４５が回転し乍ら凹部５１に移動するため、フライヤ軸１（ロータ７）は釣糸巻取り方向に支障なく回転する。
【００２３】
そして、斯かる逆転防止状態に於て、魚の引きで釣糸が繰り出されてロータ７が逆方向に回転してフライヤ軸１が同方向に回転すると、コロ４５が傾斜面５３方向に移動して内，外輪４１，４３間に食い込み、その楔作用でフライヤ軸１と逆転防止体７３が一方向クラッチ３３を介して一体となるため、係止爪３９によってロータ７の釣糸繰出し方向への回転が阻止される。
【００２４】
また、ツマミ６７をＯＦＦ方向に操作すると、係止爪３９と逆転用係止部７７との係止状態が解除されるため、逆転防止機構は逆転可能状態に切り換わってロータ７が正逆両方向へ回転可能となる。
而して、この逆転可能状態で、逆転防止体７３はコロ４５と内，外輪４１，４３との摩擦で正転方向へロータ７と供回りするが、既述したように本実施形態は、各ラチェット７５に逆転用係止部７７と、当該逆転用係止部７７と略同一またはそれ以上の寸法で径方向外方へ突出する正転用係止部７９を形成したので、逆転可能状態での急激，高速な巻取り操作中に、ツマミ６７を操作して逆転防止装置を逆転防止状態に切り換えると、係止爪３３がラチェット７５に乗り上がることなく切換えと同時に係合部５５が正転用係止部７９に係止して、ロータ７の逆転防止状態に速やかに移行することとなる。
【００２５】
このように、本実施形態によれば、逆転可能状態での急激，高速な巻取り操作中に逆転防止状態に移行しても、係止爪３９がラチェット７５に乗り上がってしまうことがないため、逆転防止体７５が空転せず直ちにロータ７の逆転防止状態に移行して実釣時の逆転防止機能が支障なく得られると共に、係止爪３９が衝接して逆転防止体７５が空転することがないため、係止爪３９やラチェット７５が摩耗，損傷することもなくなる。
【００２７】
図２は請求項１に係る逆転防止装置に用いる逆転防止体の第二実施形態を示し、本実施形態に於ける逆転防止体９１は、筒状に成形されたその外周に、図１のラチェット７５と同一形状の正，逆転用係止部７９，７７を有する２個のラチェット７５を１８０°の間隔を開けて周方向に設けると共に、各逆，正転用係止部７７，７９に隣接して切欠部９３を設けたもので、その他の逆転防止装置の構成は、図３以下の従来例と同様であるのでそれらの説明は省略する。
【００２８】
而して、上記逆転防止体９１を用いた逆転防止装置によっても、逆転可能状態での急激，高速な巻取り操作中に、ツマミ６７を操作して逆転防止装置を逆転防止状態に切り換えると、係止爪３９がラチェット７５に乗り上がることなく切換えと同時に係合部５５が正転用係止部７９に係止して、ロータ７の逆転防止状態に速やかに移行することとなる。
【００２９】
従って、この実施形態によっても、第一実施形態と同様、所期の目的を達成することが可能である。
尚、本発明の逆転防止装置は、図３以下で説明した実用新案登録第２５２４４７７号公報の逆転防止装置のみならず、その他例えば特許第３０３４７５６号公報で開示されるように操作部材でロータに制動をかける装置に使用する一方向クラッチを用いた逆転防止装置に適用できることは勿論である。
【００３０】
【発明の効果】
以上述べたように、請求項１に係る発明によれば、逆転可能状態での高速な巻取り操作中に逆転防止装置を逆転可能状態から逆転防止状態に切り換え操作すると、係止爪がラチェットに乗り上がることなく切換えと同時に正転用係止部に係止してロータの逆転防止状の逆転防止機能が支障なく得られると共に、係止爪やラチェットの摩耗，損傷がなくなる等の効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a fishing reel reverse rotation prevention device using a one-way clutch.
[0002]
[Prior art]
Today, many fishing reels, such as spinning reels, electric reels, and dual-bearing reels, are equipped with an anti-reverse device using a one-way clutch.
FIG. 3 shows a spinning reel disclosed in Utility Model Registration No. 2524477. In the figure, reference numeral 1 denotes a hollow flyer shaft (rotary body) rotatably supported by a reel body 5 via a bearing 3, A rotor 7 is fixed to the outer periphery on the front end side with a nut 9. A drive gear fixed to the handle shaft is meshed with a pinion carved on the outer periphery of the rear end side of the flyer shaft 1, and the rotor 7 is wound in the fishing line winding direction (forward rotation direction) by the winding operation of the handle 11. Rotate to.
[0003]
A pair of support arms 13 is formed on the rotor 7, and a semi-annular bail 21 is attached to the tip of both support arms 13 via a bail arm 17 fitted with a line roller 15 and a bail holder 19. It is reversibly attached to the take-off position and the fishing line discharge position.
[0004]
In the figure, reference numeral 23 denotes a spool shaft through which the flyer shaft 1 is inserted, and a spool 25 is attached to a protruding end of the spool shaft 23 on the rotor side. A traverse mechanism is mounted on the rear end side of the spool shaft 23. When the bail 21 is tilted toward the fishing line winding position and the rotor 7 is rotated in the fishing line winding direction by a handle operation, the traverse mechanism moves back and forth. When the fishing line is wound around the spool 25 moving in the traverse direction and the bale 21 is reversed to the fishing line discharge position side to cast the device, the fishing line wound around the spool 25 is fed out in a spiral shape.
[0005]
The spinning reel 27 has a reverse rotation prevention device 31 for preventing the rotor 7 from rotating in the fishing line feeding direction (reverse rotation direction) when casting or winding the fishing line inside the cylindrical portion 29 of the rotor 7. Yes.
4 and 5 show the details of the reverse rotation preventing device 31. The reverse rotation preventing device 31 is fitted and fixed to the outer periphery of the one-way clutch 33 and the one-way clutch 33 mounted on the outer periphery of the flyer shaft 1. It is composed of a cylindrical anti-reverse body 35 and a locking claw 39 that can be locked to a locking portion 69 of a ratchet 37 formed on the outer periphery of the reverse rotation preventing body 35, and between each ratchet 37, A notch 38 is formed to prevent the locking claw 39 from being pulled out.
[0006]
Thus, as shown in FIG. 5 , the one-way clutch 33 includes an inner ring 41 fixed to the outer periphery of the flyer shaft 1, an outer ring 43 to which the reverse rotation preventing body 35 is attached to the outer periphery, and the inner and outer rings 41, 43. The inner ring 41 has a circular outer periphery, and the rollers 45 are held by the spacer 47 at equal intervals. A recess (non-wedge region) 51 and an inclined surface (wedge region) 53 continuous with the roller 45 are formed on the peripheral wall of the outer ring 43, and the roller 45 is inclined by a spring 49. Is biased in the direction.
[0007]
On the other hand, the locking claw 39 is formed in plan view dogleg-shape, as shown in FIG. 4, can engage engagement portion 55 in the notch 38 is formed on the toe. The locking claw 39 is rotatably supported by the reel body 5 and is always urged by the spring member 57 in the locking direction with the locking portion 69.
[0008]
The locking claw 39 is controlled to be engageable with and disengageable from the locking portion 69 by a cam 61 provided at the tip of the operation rod 59, and a torsion spring 65 is provided between the spring hook 63 of the operation rod 59 and the reel body 5. Is built. Then, and knob 67 is attached to the operating rod 59 that protrudes to the rear of the reel body 5, as shown in FIG. 3, when operating the knob 67 in the ON direction in FIG. 4, the notch 38 as indicated by a solid line When the engaging portion 55 is engaged and the engaging claw 39 is engaged with the engaging portion 69, and the knob 67 is operated in the OFF (reversible state) direction, the cam 61 is moved as shown by a two-dot chain line. The locking claw 39 is rotated counterclockwise against the spring member 57 to release the locking state with the locking portion 69.
[0009]
The reverse rotation prevention device 31 disclosed in the utility model registration No. 2524477 is configured in this way. When the angler winds up the handle 11 with the knob 67 operated in the ON direction (in the reverse rotation prevention state), the flyer As the shaft 45 rotates forward, the roller 45 rotates and moves to the recess 51, so that the flyer shaft 1 (rotor 7) rotates without trouble in the fishing line winding direction.
[0010]
In such a state of preventing reverse rotation, when the fishing line is fed out by pulling the fish and the rotor 7 rotates in the reverse direction and the flyer shaft 1 rotates in the same direction, the roller 45 moves in the direction of the inclined surface 53 and moves inward. Since the flyer shaft 1 and the reverse rotation preventing body 35 are integrated with each other through the one-way clutch 33 by the wedge action, the engagement portion 55 is engaged with the notch portion 38, and the engagement portion 55 is engaged. The pawl 39 is locked to the locking portion 69 to prevent the rotor 7 from rotating in the fishing line feeding direction.
[0011]
Further, as described above, when the knob 67 is operated in the OFF direction, the locking state between the locking claw 39 and the locking portion 69 is released, so that the reverse rotation prevention mechanism 31 is switched to the reverse rotation enabled state and the rotor 7 Can rotate in both forward and reverse directions.
[0012]
Thus, the reverse rotation prevention device 31 switches between the reverse rotation prevention state and the reverse rotation possible state by engaging and disengaging the locking claw 39 with the ratchet 37 of the reverse rotation prevention body 35 connected to the flyer shaft 1 via the one-way clutch 33. As shown in FIG. 5, the ratchet 37 is shaped so that the locking portion 69 for preventing reverse rotation is provided so that the locking claw 39 is securely locked when the flyer shaft 1 is reversed. It was formed higher radially outward than the wall surface 71 of the ratchet 37 facing the.
[0013]
[Problems to be solved by the invention]
By the way, as described above, when the knob 67 is operated in the OFF direction, the locking state between the locking claw 39 and the locking portion 69 is released, so that the reverse rotation prevention mechanism 31 is switched to the reverse rotation enabled state, and the rotor 7. Can rotate in both forward and reverse directions, but with the winding operation of the fishing line, the anti-reverse body 35 rotates with the rotor 7 in the forward direction due to friction between the rollers 45 and the inner and outer rings 41, 43.
[0014]
Therefore, even if the knob 67 is operated to switch the reverse rotation prevention device 31 to the reverse rotation prevention state during the rapid and high speed winding operation in the reverse rotation enabled state, the locking claw 39 is not locked to the locking portion 69. There is a risk that the reverse rotation preventive body 35 may run idly on the ratchet 37, and as a result, the reverse rotation of the rotor 7 cannot be prevented instantaneously. Due to idling, the latching claw 39 and the ratchet 37 are worn and damaged, and problems such as hindering the reverse rotation prevention function remain.
[0015]
The present invention has been devised in view of such circumstances, and this kind of anti-reverse device using a one-way clutch is improved to prevent unnecessary reverse rotation of the anti-reverse body so as to prevent reverse rotation during actual fishing. An object of the present invention is to provide a fishing reel reversal prevention device with improved prevention function.
[0016]
[Means for Solving the Problems]
In order to achieve such an object, according to the first aspect of the present invention, an anti-reverse body is connected to a rotating body that rotates in conjunction with a handle operation via a one-way clutch, and the reel body is formed on the outer periphery of the anti-reverse body. In the fishing reel reverse rotation prevention device equipped with a latching claw that can be engaged and disengaged with the latching portion for preventing reverse rotation of the ratchet, the locking portion is formed on one end side in the circumferential direction of the ratchet, On the other end side of the ratchet in the circumferential direction of the reverse rotation locking portion that can be locked by the locking claw when the reverse rotation prevention body is reversely rotated, the outer diameter direction is substantially the same as or larger than the reverse rotation locking portion. projecting towards, also the reverse rotation preventing member from reverse rotation state of the reverse rotation preventing device when switching to the reverse rotation preventing state is not rotated at high speed in the forward direction, switching without the locking pawl rides on the ratchet at the same time while composed of a normal rotation locking part for locking The outer periphery of the reverse rotation locking unit and the forward rotation locking unit and the backstop member adjacent to, spaced notches concave achieving retainer locking pawl the locking pawl engages with the circumferential direction It is provided as a feature.
[0017]
(Function)
According to the first aspect of the present invention, when the reverse rotation prevention device is switched from the reverse rotation possible state to the reverse rotation prevention state during the high speed winding operation in the reverse rotation enabled state, the locking claw can be switched without climbing on the ratchet. At the same time, it is locked to the forward rotation locking portion, and the rotor is quickly shifted to the reverse rotation preventing state, and unnecessary idle rotation in the switching operation is prevented.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
Since the configuration of the reverse rotation prevention device excluding the invention part is the same as that of the conventional example shown in FIG. 3 and the subsequent drawings, the description thereof will be omitted here, and the invention part will be explained exclusively, Displayed with the same symbol.
FIG. 1 shows a first embodiment of an anti-reverse body used in the anti-reverse device according to claim 1, and the anti-reverse body 73 in this embodiment is also formed in a cylindrical shape, like the above-described anti-reverse body 35. The one-way clutch 33 is fixed to the outer periphery of the outer ring 43.
[0020]
As shown in the drawing, four ratchets 75 having a circular arc shape in plan view are formed on the outer periphery thereof at equal intervals in the circumferential direction, and the reverse rotation preventing body 73 is provided at one end side in the circumferential direction of each ratchet 75 as in the prior art. In this embodiment, in addition to such a structure, the other end in the circumferential direction of each ratchet 75 Even when the reverse rotation prevention body 73 is rotating in the forward rotation direction at a high speed when the reverse rotation prevention device is switched from the reverse rotation enabled state to the reverse rotation prevention state , the locking claw 39 does not ride on the ratchet 75 and locks simultaneously with the switching. A possible forward rotation locking portion 79 is projected outward in the radial direction with a dimension substantially the same as or larger than that of the reverse rotation locking portion 77.
[0021]
Thus, with the above-described configuration, as shown in FIG. 1, the dimension L1 from the center O of the reverse rotation preventing body 73 to the protruding end P of the forward rotation locking portion 79, and the reverse rotation from the center O of the reverse rotation preventing body 73. The dimension L2 up to the protruding end Q of the locking portion 77 has a relationship of L1 ≧ L2.
Further, in the present embodiment , the locking claw 39 is locked to the outer periphery of the reverse rotation preventing body 73 adjacent to each of the reverse rotation locking portions 77 and the forward rotation locking portion 79 as in the conventional example of FIG. In this way, concave notches 81 for securing the locking claws 39 are provided apart in the circumferential direction .
[0022]
Since the reverse rotation preventing body 73 of the reverse rotation preventing device according to the present embodiment is configured as described above, when the fisherman operates the knob 67 in the ON direction in actual fishing, the engaging portion 55 is engaged with the notch portion 81. The locking claw 39 is locked to the reverse locking portion 77. When the handle 11 is wound up in this state, the roller 45 rotates and moves to the recess 51 with the forward rotation of the flyer shaft 1, so that the flyer shaft 1 (rotor 7) has no trouble in the fishing line winding direction. Rotate.
[0023]
In such a state of preventing reverse rotation, when the fishing line is fed out by pulling the fish and the rotor 7 rotates in the reverse direction and the flyer shaft 1 rotates in the same direction, the roller 45 moves in the direction of the inclined surface 53 and moves inward. Since the flyer shaft 1 and the reverse rotation prevention body 73 are integrated with each other through the one-way clutch 33 by the wedge action, the rotation of the rotor 7 in the fishing line feeding direction is prevented by the locking claw 39. Is done.
[0024]
Further, when the knob 67 is operated in the OFF direction, the locking state between the locking claw 39 and the reverse rotation locking portion 77 is released, so that the reverse rotation prevention mechanism is switched to the reverse rotation enabled state and the rotor 7 is moved in both the forward and reverse directions. Can be rotated.
Thus, in this reversible state, the reverse rotation preventing body 73 is rotated with the rotor 7 in the forward rotation direction by friction between the rollers 45 and the inner and outer rings 41 and 43. As described above, Each ratchet 75 is formed with a reverse locking portion 77 and a forward rotation locking portion 79 projecting outward in the radial direction with a dimension substantially the same as or larger than that of the reverse rotation locking portion 77, so that the reverse rotation is possible. When the knob 67 is operated to switch the reverse rotation prevention device to the reverse rotation prevention state during the rapid and high-speed winding operation, the engaging claw 33 does not ride on the ratchet 75 and the engaging portion 55 is used for normal rotation at the same time as switching. By engaging with the engaging portion 79 , the rotor 7 is quickly shifted to the reverse rotation preventing state.
[0025]
Thus , according to the present embodiment, the locking claw 39 does not ride on the ratchet 75 even if the reverse rotation prevention state is entered during the rapid and high speed winding operation in the reverse rotation enabled state. The reverse rotation preventive body 75 does not slip freely and immediately shifts to the reverse rotation preventive state of the rotor 7 so that the reverse rotation preventive function at the time of actual fishing can be obtained without any trouble. Therefore, the locking claw 39 and the ratchet 75 are not worn or damaged.
[0027]
FIG. 2 shows a second embodiment of the anti-reverse body used in the anti-reverse device according to claim 1, and the anti-reverse body 91 in this embodiment is formed on the outer periphery formed in a cylindrical shape on the ratchet of FIG. Two ratchets 75 having forward and reverse locking portions 79 and 77 having the same shape as 75 are provided in the circumferential direction with an interval of 180 °, and adjacent to the reverse and forward rotation locking portions 77 and 79. The other parts of the reverse rotation prevention device are the same as those of the conventional example shown in FIG.
[0028]
Thus, even with the reverse rotation prevention device using the reverse rotation prevention body 91, during the rapid and high-speed winding operation in the reverse rotation enabled state, the reverse rotation prevention device is switched to the reverse rotation prevention state by operating the knob 67. The engaging portion 55 is locked to the forward rotation locking portion 79 at the same time as switching without the locking claw 39 riding on the ratchet 75, and the rotor 7 is quickly shifted to the reverse rotation preventing state.
[0029]
Therefore, also by this embodiment, it is possible to achieve the intended purpose as in the first embodiment.
The anti-reverse device of the present invention is not limited to the anti-reverse device disclosed in Japanese Utility Model Registration No. 2524477 described in FIG. 3 and subsequent figures, but also, for example, as disclosed in Japanese Patent No. 3034756, the rotor is braked against the rotor. Needless to say, the present invention can be applied to a reverse rotation prevention device using a one-way clutch used in a device for applying a force.
[0030]
【The invention's effect】
As described above, according to the first aspect of the present invention, when the reverse rotation prevention device is switched from the reverse rotation possible state to the reverse rotation prevention state during the high speed winding operation in the reverse rotation enabled state, the locking claw is turned into the ratchet. At the same time as switching without climbing, it is locked to the forward rotation locking part , and the reverse rotation prevention function of the reverse rotation prevention of the rotor can be obtained without any trouble, and the effect of eliminating the wear and damage of the locking claw and ratchet can be obtained .
