【発明の属する技術分野】
本発明は、スプ−ル内に収容した制動部材に対する防水、防塵の向上を図った魚釣用スピニングリ−ルの改良に関する。
【０００２】
【従来の技術】
魚釣用リ−ルは、海水、水、砂、塵埃、異物等が付着浸入し易い環境の厳しい釣場で使用されることより、耐食性の良好な材料や表面処理がリ−ル本体を構成する各部材に施されている。
又、これら不純物の内部浸入への防止を図り、各部が支障なく機能するために、制動装置を収容したスプ−ルに防水、防塵構造を備えたものが、特開平１１−２３９４３７号公報等で知られている。
前記公報の構成は、スプ−ル内に収容された制動機構の前部のスプ−ルとドラグノブとの間及びスプ−ル後部のスプ−ルとスプ−ル軸との間に防水用摺接部材を設けて該防水用摺接部材の弾性変形可能な摺接部を何れか一方の摺接面に摺接して、特に、スプ−ル後部からの制動機構内部への水やゴミ等の不純物の浸入をも防止することに配慮したものであり、これにより、制動機構に対する防水効果が総体的に向上された。
【０００３】
実際の釣りにおいて、対処魚や使用釣糸等に応じて好ましいドラグ力が予め強弱に設定されたり、仕掛け長さの微調節や携帯時等に必要に応じてドラグ力を緩めることがあるが、上記従来技術のように、スプ−ル後部の防水用摺接部材がスプ−ル軸の座板とスプ−ルとの間に挟着支持する場合、ドラグノブを回転操作して制動力を弱めた場合に挟着力の低下に伴ってシ−ル部材としての密閉性が低下してごく僅かな隙間が生じて水等が浸入してしまい、防水性の面において充分ではない等の課題が残されている。
【０００４】
【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、スプ−ル後部の防水用摺接部材がスプ−ル軸の座板とスプ−ルとの間に挟着支持する場合、ドラグノブを回転操作して制動力を弱めた場合に挟着力の低下に伴ってシ−ル部材としての密閉性が低下してごく僅かな隙間が生じて水等が浸入してしまい、防水性の面において充分ではないことである。
【０００５】
本発明の目的は前記欠点に鑑み、スプ−ル後部に対する防水を確実にしてスプ−ル内部の各部の機能に支障を来さぬようにした魚釣用スピニングリ−ルを提供することである。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a fishing spinning reel that is waterproof and dustproof with respect to a braking member housed in a spool.
[0002]
[Prior art]
The fishing reel is used in fishing environments where the seawater, water, sand, dust, foreign matter, etc. are likely to adhere and infiltrate, and the corrosion resistant material and surface treatment constitute the reel body. It is given to each member.
Also, in order to prevent these impurities from entering the interior and to make each part function without hindrance, a spool containing a braking device is provided with a waterproof and dustproof structure as disclosed in JP-A-11-239437, etc. Are known.
The structure of the above publication is a waterproof sliding contact between the spool and the drag knob at the front of the brake mechanism housed in the spool and between the spool and the spool shaft at the rear of the spool. Provide a member and slide the elastically deformable sliding contact portion of the waterproof sliding contact member to one of the sliding contact surfaces, in particular, impurities such as water and dust from the rear of the spool to the inside of the braking mechanism Therefore, the waterproof effect on the braking mechanism is generally improved.
[0003]
In actual fishing, a favorable drag force may be set in advance depending on the fish to be handled, the fishing line used, etc., or the drag force may be loosened as necessary for fine adjustment of the device length or when carrying it. When the sliding contact member for waterproofing at the rear part of the spool is clamped and supported between the seat plate of the spool shaft and the spool as in the case of technology, when the braking force is weakened by rotating the drag knob. As the sealing force decreases, the sealing performance as a seal member decreases, and a very small gap is generated, so that water or the like enters, leaving problems such as insufficient waterproofness. .
[0004]
[Problems to be solved by the invention]
The problem to be solved is that when the waterproof sliding contact member at the rear of the spool is sandwiched and supported between the seat plate of the spool shaft and the spool, the drag knob is rotated to weaken the braking force. In such a case, the sealing performance as the sealing member decreases with a decrease in the clamping force, and a very small gap is generated, so that water or the like enters, which is not sufficient in terms of waterproofness.
[0005]
In view of the above-mentioned drawbacks, an object of the present invention is to provide a fishing spinning reel in which waterproofing to the rear part of the spool is ensured and the function of each part inside the spool is not hindered. .
[0006]
[Means for Solving the Problems]
To solve the above problem,
In the present invention according to claim 1, the spool is rotatably fitted to the front portion of the spool shaft supported by the reel body so as not to rotate, and the spool is forwardly received. Spinning for fishing that enables adjustment of the frictional coupling force of the spool to the spool shaft by pressing the provided braking member by rotating the adjusting member screwed to the tip of the spool shaft In the brake device of the reel, the base portion of the seal member is attached and fixed to the rear side of the spool fitting support portion of the spool shaft , and the sliding contact portion of the seal member is fixed to the spool member. The gist is that the rear part can be slidably contacted .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
According to the first aspect of the present invention, the base portion 25b of the seal member 25 is attached and fixed to the circumferential groove 1f on the rear side of the spool fitting support portion 3 of the spool shaft 1 , and the slide of the seal member 25 is fixed. Since the contact portions 25d and 25e are slidably fitted to the rear portion of the spool 2, even when the drag knob 8a is rotated during actual fishing to reduce the braking force, the sealing seal 25 as the seal member 25 is used. The waterproof function of the spool 2 inside the spool 2 can be maintained and fully maintained at all times during actual fishing without deteriorating the spool function.
