【発明の属する技術分野】
本発明は、リ−ル本体の巻き取り駆動機構に連結されて巻き取り操作する魚釣用リ−ルのハンドルを、右利き又は左利きに応じて任意にハンドルを左右に取り換えることの出来る魚釣用リ−ルの改良に関する。
【０００２】
【従来の技術】
巻き取り駆動機構の駆動歯車を有する駆動軸筒の内周両側の夫々に、右ネジ及び左ネジで向きの異なる雌ネジ部を形成し、ツマミを有するハンドル軸の端部に形成した大径部と小径部に夫々に右ネジ及び左ネジで向きの異なる雄ネジ部を形成して、駆動軸筒の内周両側の夫々に形成した右ネジ及び左ネジの雌ネジ部に選択的に取り換え固定することで、右利き又は左利きに対応できるようにすることは従来から知られている。（例えば、特許文献１参照）
【０００３】
【特許文献１】
実公昭３８−１７６号公報
【０００４】
このように、ハンドルを取り換え固定することで、右利き又は左利きに対応できるようにハンドル軸の端部に形成される螺合部は、同径軸の外周上に左右向きの異なる雄ネジ部は刻設出来ないので、大小径の異なる段付き外径部に左右向きの異なる雄ネジ部を形成して駆動軸筒の内周の雌ネジ部に螺合させることになる。
【０００５】
【発明が解決しようとする課題】
解決しようとする問題点は、特許文献１のように、左右取り換えハンドル軸の雄ネジ部を駆動軸筒の内周の雌ネジ部に螺合する際に、ハンドル軸端部の小径雄ネジ部を駆動軸筒内周の大径雌ネジ部に干渉させないでハンドル軸の大径雄ネジ部を大径雌ネジ部に螺合させる必要があること、及び、螺合締め付け強度は小径ネジ部の強度を基本に大径ネジ部が設定されること等より、必要以上に駆動軸筒の内周、つまり、駆動軸筒が大径化してしまい、結果的に、巻き取り駆動部を収容するリ−ル本体が大型・重量化してしまうことになり、魚釣り操作性、携帯性が悪くなってしまう。
ことである。
【０００６】
本発明の目的は前記欠点に鑑み、ハンドルねじ込み式左右変換構造の駆動軸の小径化を図ると共にリ−ル本体の小型・軽量化を図った魚釣用リ−ルを提供することである。
【０００７】
【課題を解決するための手段】
上記課題を解決するために、
請求項１に係わる本発明は、リ−ル本体に支持された駆動歯車を駆動回転する軸部の左右に螺子方向の異なる大径螺子部と小径螺子部を設けて該大径螺子部と小径螺子部に夫々螺合する螺子部をハンドル側の軸芯上に並べて設けた魚釣用リ−ルにおいて、前記駆動歯車側又はハンドル側に形成される大径雌螺子部と小径雄螺子部の少なくとも何れか一方のネジ山の頂部をカットしたことを要旨とするものである。
【０００８】
【発明の実施の形態】
請求項１の本発明により、ハンドルを、右利き又は左利きに対応するように、駆動歯車２の駆動回転する軸部（駆動軸筒２ａ、駆動軸部２ｉ）に右ネジの小径雌螺子部２ｂと左ネジの大径雌螺子部２ｃ又は右ネジの大径雄螺子部２ｍと左ネジの小径雄螺子部２ｋを設けると共に、ハンドル軸３、３′に右ネジの小径雄螺子部３ａと左ネジの大径雄螺子部３ｂ又は左ネジの小径雌螺子部３ｄと右ネジの大径雌螺子部３ｅを設けて何れかを選択的に取り付けるに際して螺子同士が干渉することがなく、駆動回転する軸部が必要以上に大型化するのを防止でき、リ−ル本体の小型・軽量化が可能となる。

[0002]
[Prior art]
A large-diameter portion formed at the end of a handle shaft having a knob by forming female threads in different directions with a right-hand screw and a left-hand screw on both inner circumferential sides of a drive shaft cylinder having a drive gear of a winding drive mechanism. The right-hand thread and the left-hand thread are formed on the small-diameter part with male threads in different directions, respectively, and are selectively replaced and fixed to the right-hand and left-hand female threads formed on both inner circumferential sides of the drive shaft cylinder. It has been conventionally known to be able to respond to right-handed or left-handed. (For example, see Patent Document 1)
[0003]
[Patent Document 1]
Japanese Utility Model Publication No. 38-176
In this way, by replacing and fixing the handle, the threaded portion formed at the end of the handle shaft so as to be able to cope with right-handed or left-handed use is a male screw portion that is different from side to side on the outer circumference of the same diameter shaft. Since it cannot be engraved, left and right different external thread portions are formed on the stepped outer diameter portions having different large and small diameters, and screwed to the internal thread portion on the inner periphery of the drive shaft cylinder.
[0005]
[Problems to be solved by the invention]
The problem to be solved is that, as in Patent Document 1, when the male screw portion of the left-right replacement handle shaft is screwed into the female screw portion on the inner periphery of the drive shaft cylinder, a small-diameter male screw portion at the end of the handle shaft is used. It is necessary to screw the large-diameter male thread of the handle shaft into the large-diameter female thread without interfering with the large-diameter female thread on the inner periphery of the drive shaft cylinder. The inner diameter of the drive shaft cylinder, that is, the diameter of the drive shaft cylinder becomes larger than necessary due to the setting of the large diameter screw portion on the basis of the above. The main body becomes large and heavy, and the operability of fishing and portability are deteriorated.
That is.
[0006]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a fishing reel in which a drive shaft of a handle screw-in left-right conversion structure is reduced in size and a reel body is reduced in size and weight in view of the above drawbacks.

[Means for Solving the Problems]
In order to solve the above problems,
According to the first aspect of the present invention, a large-diameter screw portion and a small-diameter screw portion having different screw directions are provided on the left and right of a shaft portion for driving and rotating a driving gear supported by a reel body. In a fishing reel in which screw portions respectively screwed to the screw portions are arranged on the shaft core on the handle side, a large-diameter female screw portion and a small-diameter male screw portion formed on the drive gear side or the handle side are provided. The gist of the invention is that at least one of the thread crests is cut.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
According to the first aspect of the present invention, a small-diameter female screw portion 2b of a right-hand thread is attached to a shaft portion (drive shaft tube 2a, drive shaft portion 2i) of the drive gear 2 that rotates by driving so that the handle corresponds to right-handed or left-handed. And a large-diameter female screw portion 2c of a left-hand screw or a large-diameter male screw portion 2m of a right-hand screw and a small-diameter male screw portion 2k of a left-hand screw, and a small-diameter male screw portion 3a of a right-hand screw and a left-hand screw on the handle shafts 3 and 3 '. When a large-diameter male screw 3b or a small-diameter female screw 3d with a left-hand screw and a large-diameter female screw 3e with a right-hand screw are provided and selectively attached, the screws do not interfere with each other, and the shaft portion is driven and rotated.
