Description

本発明は、魚釣用リールに関し、詳しくは、磁性流体を用いたドラグ機構を有する魚釣用リールに関する。 The present invention relates to a fishing reel, and more particularly to a fishing reel having a drag mechanism using a magnetic fluid.

従来より、釣糸が強く引かれたときの糸切れを防止するドラグ機構を備えた魚釣用リールが知られている。このドラグ機構は、例えば、スプールに対して制動板を押圧して静止摩擦力を作用させることにより、この静止摩擦力を超える力で魚が釣糸を引き込んだときに、スプールと制動板とが滑ってスプールが回転するようになっている（例えば、特許文献１参照）。 DESCRIPTION OF RELATED ART Conventionally, the fishing reel provided with the drag mechanism which prevents a thread break when a fishing line is pulled strongly is known. This drag mechanism, for example, presses the brake plate against the spool and applies a static friction force, so that when the fish pulls in the fishing line with a force exceeding the static friction force, the spool and the brake plate slip. Thus, the spool rotates (see, for example, Patent Document 1).

特開２０１０−２５２７６０号公報JP 2010-252760 A

しかしながら、こうしたスプールに制動板を押圧する機構では、スプールの回転軸と制動板とが滑る際（作用する摩擦力が静止摩擦力から動摩擦力へと変化する際）にスティックスリップ現象によって異音が生じるという問題がある。また、制動板の劣化に伴ってドラグ性能が低下してしまう恐れがある。 However, in such a mechanism that presses the brake plate against the spool, when the rotating shaft of the spool and the brake plate slide (when the applied frictional force changes from a static frictional force to a dynamic frictional force), abnormal noise is generated due to the stick-slip phenomenon. There is a problem that arises. In addition, there is a risk that the drag performance may be reduced with the deterioration of the brake plate.

そこで、本発明は、制動板による摩擦力以外の制動力によりスプールを制動することができる魚釣用リールを提供することを目的の一つとする。本発明の様々な実施形態の他の目的は、本明細書全体を参照することにより明らかとなる。 Therefore, an object of the present invention is to provide a fishing reel capable of braking a spool by a braking force other than a frictional force by a braking plate.

図１は、本発明の一実施形態に係る魚釣用リール１０の一部を断面とした部分断面図である。この魚釣用リール１０は、図示するように、リール本体１２と、このリール本体１２の前方に回転可能に設けられ、釣糸を案内する釣糸案内部２０ａを有するロータ２０と、このロータ２０の内側に設けられロータ２０の回転に応じて釣糸案内部２０ａを介して巻き取られた釣糸が巻かれるスプール３０とを備える。魚釣用リール１０は、リール本体１２に設けられた略Ｔ字形状の脚部１２ａを介して図示しない釣竿に取り付けられて用いられる。魚釣用リール１０は、ドラグ機構以外は、一般的なスピニングリールと同様の構成を備え得る。スピニングリールは、本発明を適用可能なリールの例に過ぎず、後述するように、本発明は、スピニングリール以外の様々な種類のリール（例えば、両軸受型リール、片軸受型リール、及び電動リール）に適用可能である。 FIG. 1 is a partial cross-sectional view of a part of a fishing reel 10 according to an embodiment of the present invention. As shown in the figure, the fishing reel 10 includes a reel body 12, a rotor 20 that is rotatably provided in front of the reel body 12 and has a fishing line guide portion 20 a that guides the fishing line, and an inner side of the rotor 20. And a spool 30 on which the fishing line wound up via the fishing line guide portion 20a according to the rotation of the rotor 20 is wound. The fishing reel 10 is used by being attached to a fishing rod (not shown) via a substantially T-shaped leg portion 12 a provided on the reel body 12. The fishing reel 10 can have the same configuration as a general spinning reel except for the drag mechanism. The spinning reel is merely an example of a reel to which the present invention can be applied. As will be described later, the present invention is applicable to various types of reels other than the spinning reel (for example, a double-bearing reel, a single-bearing reel, and an electric motor). Reel).

リール本体１２には、一端にハンドル１４が取り付けられたハンドル軸１６が回転可能に支持されており、このハンドル軸１６にはドライブギヤ１８が取り付けられている。ハンドル軸１６は、ハンドル１４の回転操作に応じて回転するようにリール本体１２に取り付けられる。ドライブギヤ１８には、ハンドル軸１６の軸方向に対して直交する方向に延出する略円筒形状のピニオンギヤ１９が噛合している。このピニオンギヤ１９はロータ２０と一体に取り付けられている。このため、ハンドル１４の回転は、ハンドル軸１４、ドライブギヤ１８、及びピニオンギヤ１９を介してロータ２０に伝達される。 A handle shaft 16 having a handle 14 attached to one end thereof is rotatably supported on the reel body 12, and a drive gear 18 is attached to the handle shaft 16. The handle shaft 16 is attached to the reel body 12 so as to rotate in accordance with the rotation operation of the handle 14. The drive gear 18 meshes with a substantially cylindrical pinion gear 19 that extends in a direction orthogonal to the axial direction of the handle shaft 16. The pinion gear 19 is attached integrally with the rotor 20. Therefore, the rotation of the handle 14 is transmitted to the rotor 20 through the handle shaft 14, the drive gear 18, and the pinion gear 19.

また、ピニオンギヤ１９にはスプール軸３１が貫通している。このスプール軸３１の後側端部（手元端）には、ドライブギヤ１８の回転に応じて動作するオシレート機構２２が連結されており、スプール軸３１の先端側にはスプール３０が取り付けられている。このオシレート機構２２の動作によってスプール軸３１及びその先端側に取り付けられたスプール３０は、リール本体１２の前後方向（ハンドル軸１６と直交する方向）に往復運動する。 A spool shaft 31 passes through the pinion gear 19. An oscillating mechanism 22 that operates in accordance with the rotation of the drive gear 18 is connected to the rear end (proximal end) of the spool shaft 31, and the spool 30 is attached to the front end side of the spool shaft 31. . By the operation of the oscillating mechanism 22, the spool shaft 31 and the spool 30 attached to the tip end side thereof reciprocate in the front-rear direction of the reel body 12 (direction perpendicular to the handle shaft 16).

このように、ハンドル１４の回転操作に応じてドライブギヤ１８が回転すると、ピニオンギヤ１９を介してロータ２０が回転すると共にオシレート機構２２及びスプール軸３１を介してスプール３０が往復運動するから、ロータ２０の釣糸案内部２０ａによって巻き取られる釣糸はスプール３０に軸方向に均一に巻かれる。 Thus, when the drive gear 18 rotates according to the rotation operation of the handle 14, the rotor 20 rotates through the pinion gear 19 and the spool 30 reciprocates through the oscillating mechanism 22 and the spool shaft 31. The fishing line wound up by the fishing line guide portion 20a is uniformly wound around the spool 30 in the axial direction.

図２は、一実施形態における魚釣用リール１０のスプール３０周辺の縦断面図であり、図３は、図２のＡ−Ａ線に沿う横断面図である。図示するように、スプール軸３１には、円筒形状のスプール支持部材３２がピン止めによって固定されている。このスプール支持部材３２には、スプール３０が軸受３３ａを介してスプール軸３１を中心として回転できるように支持されている。スプール３０の前方内側には、後述する回転部材３５が、スプール３０の回転と連動して回転するように取り付けられている。また、スプール支持部材３２の前方には、後述するように、スプール軸３１と略同心に、略円筒形状の固定部材３６が固定されている。この固定部材３６は、軸受３３ｂ、３３ｃを介して回転部材３５を回転可能に支持する。 FIG. 2 is a longitudinal sectional view around the spool 30 of the fishing reel 10 in one embodiment, and FIG. 3 is a transverse sectional view taken along line AA in FIG. As shown in the drawing, a cylindrical spool support member 32 is fixed to the spool shaft 31 by pinning. The spool support member 32 supports the spool 30 through a bearing 33a so as to be rotatable about the spool shaft 31. A rotating member 35 described later is attached to the front inner side of the spool 30 so as to rotate in conjunction with the rotation of the spool 30. A substantially cylindrical fixing member 36 is fixed in front of the spool support member 32 so as to be substantially concentric with the spool shaft 31 as described later. The fixing member 36 rotatably supports the rotating member 35 via bearings 33b and 33c.

さらに、スプール軸３１の前側端部には、回転部材３５と固定部材３６とのスプール３０の回転軸方向（スプール軸３１の軸方向）の位置を調整するための蓋状の調整部材３７が取り付けられている。調整部材３７は、スプール軸３１に螺合しており、調整部材３７をねじ込むことにより、固定部材３６をスプール軸３１の軸方向後側に押し込むことができる。固定部材３６は、バネＳにより、スプール軸３１の前側に常時付勢されている。 Further, a lid-like adjusting member 37 for adjusting the position of the rotating member 35 and the fixed member 36 in the rotating shaft direction of the spool 30 (the axial direction of the spool shaft 31) is attached to the front end portion of the spool shaft 31. It has been. The adjustment member 37 is screwed into the spool shaft 31, and the fixing member 36 can be pushed into the rear side in the axial direction of the spool shaft 31 by screwing the adjustment member 37. The fixing member 36 is always urged to the front side of the spool shaft 31 by the spring S.

回転部材３５は、スプール軸３１と略同心に配置され、前側に開口した略円筒形状を有する円筒部材３５ｄと、この円筒部材３５ｄの側壁部の径方向内側に配置された円環状の外側リング部材３５ｂと、この外側リング部材３５ｂの径方向内側に配置され、その外周面が外側リング部材３５ｂの内周面よりも小さくなるように構成された内側リング部材３５ｃと、を備える。この外側リング部材３５ｂの内周面と、内側リング部材３５ｃの外周面により、略円筒形状の収容溝３５ａが画定される。つまり、外側リング部材３５ｂは、収容溝３５ａの径方向外側の壁を形成し、内側リング部材３５ｃは、収容溝３５ａの径方向内側の壁を形成する。この収容溝３５ａの後端は円筒部材３５ｄにより閉塞されているが、前端側は開口している。 The rotating member 35 is arranged substantially concentrically with the spool shaft 31 and has a cylindrical member 35d having a substantially cylindrical shape opened to the front side, and an annular outer ring member arranged radially inside the side wall portion of the cylindrical member 35d. 35b, and an inner ring member 35c that is arranged on the radially inner side of the outer ring member 35b and is configured such that the outer peripheral surface thereof is smaller than the inner peripheral surface of the outer ring member 35b. A substantially cylindrical accommodation groove 35a is defined by the inner peripheral surface of the outer ring member 35b and the outer peripheral surface of the inner ring member 35c. That is, the outer ring member 35b forms a radially outer wall of the receiving groove 35a, and the inner ring member 35c forms a radially inner wall of the receiving groove 35a. The rear end of the accommodation groove 35a is closed by a cylindrical member 35d, but the front end side is open.

外側リング部材３５ｂ及び内部リング部材３５ｃは、鉄系の磁性体の材料から形成される。外側リング部材３５ｂには、略円環状の永久磁石３９ｂが設けられている。永久磁石３９ｂは、その内周面が収容溝３５ａに露出するように、外側リング部材３５ｂの内周面側に嵌め込まれている。また、内側リング部材３５ｃには、略円環状の２つの永久磁石３９ａ、３９ｃが設けられている。永久磁石３９ａ、３９ｃの各々は、その外周面が収容溝３５ａに露出するように、内側リング部材３５ｃの外周面側に嵌め込まれている。これらの永久磁石は、図示するように、スプール３０の回転軸方向後方から前方に向かって、永久磁石３９ａ、３９ｂ、３９ｃの順に配置されている。この永久磁石３９ａ、３９ｂ、３９ｃは、回転部材３５がスプール３０の回転に応じて回転するときに、外側リング部材３５ｂ及び内部リング部材３５ｃとともに回転するように、それぞれ対応する外側リング部材３５ｂ及び内部リング部材３５ｃに固定される。 The outer ring member 35b and the inner ring member 35c are made of an iron-based magnetic material. The outer ring member 35b is provided with a substantially annular permanent magnet 39b. The permanent magnet 39b is fitted on the inner peripheral surface side of the outer ring member 35b so that the inner peripheral surface thereof is exposed in the housing groove 35a. The inner ring member 35c is provided with two substantially annular permanent magnets 39a and 39c. Each of the permanent magnets 39a and 39c is fitted on the outer peripheral surface side of the inner ring member 35c so that the outer peripheral surface thereof is exposed in the accommodation groove 35a. These permanent magnets are arranged in the order of permanent magnets 39a, 39b, and 39c from the rear to the front in the rotational axis direction of the spool 30, as shown in the figure. The permanent magnets 39a, 39b, and 39c are respectively connected to the corresponding outer ring member 35b and the inner ring member 35b so that they rotate together with the outer ring member 35b and the inner ring member 35c when the rotating member 35 rotates according to the rotation of the spool 30. It is fixed to the ring member 35c.

固定部材３６は、非磁性体の材料から成り、略円筒状に構成されている。この固定部材３６は、スプール軸３１の周方向に延びる外壁部３６ａと、外壁部３６ａの前端から径方向内側に延びる略円板形状の底部３６ｄと、この底部３６ｄの径方向内側端部からスプール軸３１の軸方向に延びる筒状の内壁部３６ｃとを有する。外壁部３６ａには、複数の貫通孔３６ｂが形成されている。図３に示されているように、内壁部３６ｃは、位置調整部材３７の突出部３７ａに嵌め込まれており、また、内壁部３６ｃの後側端部はさらにスプール支持部材３２の前側端部に回り止め状態で軸方向移動可能に嵌め込まれている。このため、固定部材３６は、スプール支持部材３２と位置調整部材３７の突出部３７ａを介して、スプール軸３１上に、軸方向移動可能に回り止めされた状態で支持されている。 The fixing member 36 is made of a nonmagnetic material and has a substantially cylindrical shape. The fixing member 36 includes an outer wall portion 36a extending in the circumferential direction of the spool shaft 31, a substantially disc-shaped bottom portion 36d extending radially inward from the front end of the outer wall portion 36a, and a spool extending from the radially inner end portion of the bottom portion 36d. A cylindrical inner wall portion 36 c extending in the axial direction of the shaft 31. A plurality of through holes 36b are formed in the outer wall portion 36a. As shown in FIG. 3, the inner wall portion 36 c is fitted into the protruding portion 37 a of the position adjusting member 37, and the rear side end portion of the inner wall portion 36 c is further connected to the front side end portion of the spool support member 32. It is fitted so that it can move in the axial direction in a non-rotating state. For this reason, the fixing member 36 is supported on the spool shaft 31 through the spool support member 32 and the protruding portion 37a of the position adjusting member 37 in a state in which it is prevented from rotating in the axial direction.

また、外壁部３６ａは、少なくとも貫通孔３６ｂを有する部分が回転部材３５の収容溝３５ａに隙間を保持して収容されるように配置されている。つまり、外壁部３６ａが収容溝３５ａに収容された状態において、外壁部３６ａと収容溝３５ａを画定する壁部（つまり、外側リング部材３５ｂの内周面及び内部リング部材３５ｃの外周面）との間には、後述するように磁性流体（ＭＲ流体）（図２及び図３では図示を省略した）を受け入れ可能な隙間が確保されている。ＭＲ流体は、マグネタイト等の強磁性体の微細粉末が液体中に均一に分散する複合材料であり、強い磁力が作用する環境下においても粒子の凝集や固液の分離がおこらず、磁性流体全体が強磁性を有するように挙動し、磁力に応じてせん断応力（粘度）が変化するという特徴を有する。本発明には、任意の種類のＭＲ流体を適用することができるが、オイルベースのＭＲ流体を用いるのが好ましい。こうすれば、外部から水分が浸入してＭＲ流体に付着しても、オイルベースであるＭＲ流体に混ざることがない。一方、従来の制動板による摩擦力を用いた方式では、水分の付着によって制動板等の部材が劣化してドラグ性能が低下していまう。また、例えば、特開昭６３−１６４８２８号公報に記載されているドラグ機構のように、磁力を作用させた磁性粉粒と回転板との摩擦力とを用いて制動力を作用させる方式では、同じく、水分の付着によって磁性粉粒が劣化してドラグ性能が低下してしまう。ＭＲ流体をオイルベースとすることにより、こうした水分の付着に伴う問題が生じないから、ＭＲ流体を収容する収容溝３５ａ等を密閉する必要がなくなり、製造工程が複雑化することも回避できる。 Further, the outer wall portion 36 a is arranged so that at least a portion having the through hole 36 b is accommodated in the accommodation groove 35 a of the rotating member 35 with a gap therebetween. That is, in a state where the outer wall portion 36a is housed in the housing groove 35a, the outer wall portion 36a and the wall portions that define the housing groove 35a (that is, the inner peripheral surface of the outer ring member 35b and the outer peripheral surface of the inner ring member 35c). A gap that can receive a magnetic fluid (MR fluid) (not shown in FIG. 2 and FIG. 3) is secured between them. MR fluid is a composite material in which fine powder of ferromagnetic material such as magnetite is uniformly dispersed in a liquid, and does not cause aggregation of particles or separation of solid and liquid even in an environment where a strong magnetic force acts. Behaves like having ferromagnetism, and the shear stress (viscosity) changes according to the magnetic force. Although any type of MR fluid can be applied to the present invention, it is preferable to use an oil-based MR fluid. In this way, even if moisture enters from the outside and adheres to the MR fluid, it does not mix with the MR fluid that is an oil base. On the other hand, in the method using the frictional force by the conventional brake plate, the members such as the brake plate are deteriorated due to the adhesion of moisture, and the drag performance is lowered. Further, for example, as in the drag mechanism described in Japanese Patent Application Laid-Open No. 63-164828, in a method in which a braking force is applied using a frictional force between magnetic particles and a rotating plate on which a magnetic force is applied, Similarly, magnetic particles are deteriorated due to adhesion of moisture, and drag performance is lowered. By using the MR fluid as the oil base, such a problem associated with the adhesion of moisture does not occur. Therefore, it is not necessary to seal the accommodation groove 35a for accommodating the MR fluid, and the manufacturing process can be prevented from becoming complicated.

次に、図４を参照して、固定部材３６についてさらに説明する。図４は、一実施形態における固定部材３６の外観図である。図示するように、固定部材３６の外壁部３６ａには、スプール３０の回転軸方向略中央の位置に外周に沿って形成された複数の貫通孔３６ｂ１と、貫通孔３６ｂ１よりも回転軸方向後側の位置に外周に沿って形成された複数の貫通孔３６ｂ２とが形成されており、貫通孔３６ｂ２の方が貫通孔３６ｂ１よりも大きな開口面積（体積）で形成されている。このように、スプール３０の回転軸方向の位置に応じて異なる大きさの貫通孔とすることにより、段階的ではないスムーズな制動力の増減調節が可能となる。 Next, the fixing member 36 will be further described with reference to FIG. FIG. 4 is an external view of the fixing member 36 according to the embodiment. As shown in the drawing, the outer wall 36a of the fixing member 36 has a plurality of through holes 36b1 formed along the outer periphery at a position substantially in the center in the rotation axis direction of the spool 30, and a rear side in the rotation axis direction from the through hole 36b1. A plurality of through-holes 36b2 formed along the outer periphery are formed at the position, and the through-hole 36b2 is formed with a larger opening area (volume) than the through-hole 36b1. In this way, by making the through-holes having different sizes depending on the position of the spool 30 in the rotation axis direction, smooth increase / decrease adjustment of the braking force is possible in a stepwise manner.

図２に戻り、位置調整部材３７は、蓋状の本体から後方に延びると共に内周面に雌ネジを有する突出部３７ａを有する。この突出部３７ａは固定部材３６の中空部（内壁部３６ｃの径方向内側）にはめ込まれている。この突出部３７ａと、雄ネジが形成されたスプール軸３１の前側端部とが螺合している。このため、位置調整部材３７を回転させると位置調整部材３７のスプール３０の回転軸方向の位置が移動し、位置調整部材３７の蓋状の本体が当接する固定部材３６の回転軸方向の位置も移動する。よって、位置調整部材３７を回転操作することにより、固定部材３６が有する貫通孔３６ｂ１、３６ｂ２と回転部材３５が有する永久磁石３９ａ、３９ｂ、３９ｃとの、回転軸方向の相対的な位置を調整することができる。 Returning to FIG. 2, the position adjustment member 37 has a protrusion 37 a that extends rearward from the lid-shaped main body and has an internal thread on the inner peripheral surface. The projecting portion 37a is fitted in the hollow portion of the fixing member 36 (inner side in the radial direction of the inner wall portion 36c). The projecting portion 37a and the front end portion of the spool shaft 31 on which the male screw is formed are screwed together. For this reason, when the position adjustment member 37 is rotated, the position of the position adjustment member 37 in the rotation axis direction of the spool 30 is moved, and the position of the fixing member 36 in contact with the lid-shaped main body of the position adjustment member 37 is also changed. Moving. Therefore, by rotating the position adjusting member 37, the relative positions of the through holes 36b1 and 36b2 of the fixed member 36 and the permanent magnets 39a, 39b and 39c of the rotating member 35 in the rotation axis direction are adjusted. be able to.

回転部材３５の収容溝３５ａに収容されているＭＲ流体（Magneto Rheological Fluid）は、回転部材３５が有する永久磁石３９に吸着される。ＭＲ流体のせん断応力は、この永久磁石３９から受ける磁力の強さに応じて変化する。回転部材３５にスプール軸３１周りのトルクが作用すると、収容溝３５ａ及び貫通孔３６ｂに収容されているＭＲ流体によって回転部材３５と固定部材３６との間に、ＭＲ流体に永久磁石３９から作用する磁力の強さに応じたせん断抵抗が発生する。固定部材３６はスプール軸３１に対して回り止め固定されているので、このせん断抵抗によって、上記トルクによる回転部材３５の回転が制動される。ＭＲ流体に回転部材３５から作用するせん断力がＭＲ流体によるせん断応力を超えると、回転部材３５は共に回転することとなる。このように、魚釣用リール１０においては、ＭＲ流体のせん断応力に応じた制動力をスプール３０に対して作用させるドラグ機構が実現される。 MR fluid (Magneto Rheological Fluid) accommodated in the accommodation groove 35 a of the rotating member 35 is attracted to the permanent magnet 39 of the rotating member 35. The shear stress of the MR fluid changes according to the strength of the magnetic force received from the permanent magnet 39. When torque around the spool shaft 31 acts on the rotating member 35, the MR fluid accommodated in the housing groove 35a and the through hole 36b acts on the MR fluid from the permanent magnet 39 between the rotating member 35 and the fixed member 36. Shear resistance is generated according to the strength of the magnetic force. Since the fixing member 36 is fixed to the spool shaft 31, the rotation of the rotating member 35 due to the torque is braked by the shear resistance. When the shearing force acting on the MR fluid from the rotating member 35 exceeds the shearing stress due to the MR fluid, the rotating member 35 rotates together. Thus, in the fishing reel 10, a drag mechanism is realized that applies a braking force according to the shear stress of the MR fluid to the spool 30.

ここで、一実施形態の魚釣用リール１０においてドラグ力を調整する機構について詳述する。まず、回転部材３５の収容溝３５ａ周辺に形成される磁界の様子を図５を用いて説明する。図５は、永久磁石３９によって収容溝３５ａに形成される磁界の様子を模式的に示す説明図である。回転部材３５に設けられた永久磁石３９ａ、３９ｂ、３９ｃは、前側（図５の左側）がＮ極、後側（図５の右側）がＳ極となるように配置されており、隣接する２つの磁石のうち一方の磁石が外側リング部材３５ｂに設けられ、他方の磁石が内側リング部材３５ｃに設けられている。図５において点線で示すように、収容溝３５ａにおいては、各磁石のＮ極からＳ極へと略楕円形状に複数の磁力線（磁束）が形成される。また、スプール３０の回転軸方向に隣接する磁石間の領域（永久磁石３９ａと永久磁石３９ｂ間の領域、及び、永久磁石３９ｂと永久磁石３９ｃの間の領域）においては、各磁石それぞれによって形成される方向性が同一の磁束が重複するから、その他の領域と比較して強い磁界が形成される。 Here, the mechanism for adjusting the drag force in the fishing reel 10 of one embodiment will be described in detail. First, the state of the magnetic field formed around the accommodation groove 35a of the rotating member 35 will be described with reference to FIG. FIG. 5 is an explanatory view schematically showing the state of the magnetic field formed in the accommodation groove 35 a by the permanent magnet 39. The permanent magnets 39a, 39b, and 39c provided on the rotating member 35 are arranged so that the front side (left side in FIG. 5) is an N pole and the rear side (right side in FIG. 5) is an S pole. One of the two magnets is provided on the outer ring member 35b, and the other magnet is provided on the inner ring member 35c. As indicated by dotted lines in FIG. 5, in the accommodating groove 35a, a plurality of magnetic lines (magnetic flux) are formed in an approximately elliptical shape from the N pole to the S pole of each magnet. Further, the areas between the magnets adjacent to each other in the rotation axis direction of the spool 30 (the area between the permanent magnet 39a and the permanent magnet 39b and the area between the permanent magnet 39b and the permanent magnet 39c) are formed by the respective magnets. Since magnetic fluxes having the same directionality overlap, a strong magnetic field is formed as compared with other regions.

図６は、固定部材３６の貫通孔３６ｂ１のスプール３０の回転軸方向における位置が回転部材３５の永久磁石３９ｃの位置と略同一となり、貫通孔３６ｂ２の位置が永久磁石３９ｂの位置と略同一となるように、回転部材３５と固定部材３６とのスプール３０の回転軸方向の位置が調整された場合のドラグ機構（回転部材３５及び固定部材３６）の断面図である。また、図７は、固定部材３６の貫通孔３６ｂ１のスプール３０の回転軸方向の位置が回転部材３５の永久磁石３９ｂと永久磁石３９ｃの間の位置となり、貫通孔３６ｂ２の位置が永久磁石３９ａと永久磁石３９ｂの間の位置となるように、回転部材３５と固定部材３６とのスプール３０の回転軸方向の位置が調整された場合のドラグ機構の断面図であり、図８はこの図７のＢ−Ｂ断面図である。図５を用いて説明したように、隣接する磁石間の領域には、他の領域と比較して強い磁界が形成されているから、固定部材３６の貫通孔３６ｂが隣接する磁石間の領域に位置する図７の状態の方が、図６の状態よりも、貫通孔３６ｂ内のＭＲ流体に作用する磁力が強くなる。この結果、図７の状態の方が、図６の状態よりも貫通孔３６ｂ内のＭＲ流体のせん断応力が大きくなり、スプール３０に作用する制動力も大きくなる。このように、一実施形態の魚釣用リール１０においては、固定部材３６が有する貫通孔３６ｂと回転部材３５が有する永久磁石３９との、スプール３０の回転軸方向の相対的な位置を調整することにより、スプール３０に対する制動力を調整することができる。この固定部材３６が有する貫通孔３６ｂと回転部材３５が有する永久磁石３９との相対位置の調整は、上記のように、位置調整部材３７を操作することにより行われる。 In FIG. 6, the position of the through hole 36b1 of the fixed member 36 in the rotational axis direction of the spool 30 is substantially the same as the position of the permanent magnet 39c of the rotating member 35, and the position of the through hole 36b2 is substantially the same as the position of the permanent magnet 39b. It is sectional drawing of the drag mechanism (the rotation member 35 and the fixing member 36) when the position of the rotation axis direction of the spool 30 of the rotation member 35 and the fixing member 36 is adjusted. In FIG. 7, the position of the through hole 36b1 of the fixed member 36 in the rotation axis direction of the spool 30 is a position between the permanent magnet 39b and the permanent magnet 39c of the rotating member 35, and the position of the through hole 36b2 is the permanent magnet 39a. FIG. 8 is a cross-sectional view of the drag mechanism when the position of the rotating member 35 and the fixing member 36 in the rotation axis direction of the spool 30 is adjusted so as to be between the permanent magnets 39b. It is BB sectional drawing. As described with reference to FIG. 5, since a strong magnetic field is formed in the region between adjacent magnets as compared with other regions, the through hole 36 b of the fixing member 36 is formed in the region between adjacent magnets. In the state shown in FIG. 7, the magnetic force acting on the MR fluid in the through hole 36b is stronger than in the state shown in FIG. As a result, in the state of FIG. 7, the shear stress of the MR fluid in the through hole 36 b is larger than in the state of FIG. 6, and the braking force acting on the spool 30 is also greater. As described above, in the fishing reel 10 according to the embodiment, the relative position of the through-hole 36b of the fixing member 36 and the permanent magnet 39 of the rotating member 35 in the rotation axis direction of the spool 30 is adjusted. Thus, the braking force for the spool 30 can be adjusted. Adjustment of the relative position between the through hole 36b of the fixing member 36 and the permanent magnet 39 of the rotating member 35 is performed by operating the position adjusting member 37 as described above.

以上説明した一実施形態に係る魚釣用リール１０は、スプール３０の回転と連動して回転し永久磁石３９を有する回転部材３５と、回転部材３５の収容溝３５ａに収容される部分に貫通孔３６ｂが形成された外壁部３６ａを有し、スプール支持部材３２や位置調整部材３７（突出部３７ａ）を介してスプール軸３１に回り止め固定された固定部材３６と、収容溝３５ａにおける回転部材３５と固定部材３６との隙間に収容されたＭＲ流体とを備え、永久磁石３９の磁力の作用によって上昇するＭＲ流体のせん断応力に応じた制動力をスプール３０に対して作用させることができる。 The fishing reel 10 according to the embodiment described above includes a rotating member 35 that rotates in conjunction with the rotation of the spool 30 and has a permanent magnet 39, and a through hole in a portion of the rotating member 35 that is accommodated in the accommodating groove 35a. A fixing member 36 having an outer wall portion 36a formed with 36b and fixed to the spool shaft 31 via a spool support member 32 and a position adjusting member 37 (projecting portion 37a), and a rotating member 35 in the accommodation groove 35a. And the MR fluid accommodated in the gap between the fixed member 36 and a braking force corresponding to the shear stress of the MR fluid that is raised by the action of the magnetic force of the permanent magnet 39 can be applied to the spool 30.

また、固定部材３６が有する貫通孔３６ｂと回転部材３５が有する永久磁石３９との、スプール３０の回転軸方向の相対的な位置を調整することにより、ドラグ力を調整することができるから、容易にドラグ力を調整することができる。 In addition, since the drag force can be adjusted by adjusting the relative positions of the through holes 36b of the fixing member 36 and the permanent magnets 39 of the rotating member 35 in the rotation axis direction of the spool 30, it is easy. The drag force can be adjusted.

一実施形態における魚釣用リール１０では、回転部材３５の外側リング部材３５ｂに略円環状の永久磁石３９ｂを有し、内側リング部材３５ｃに略円環状の２つの永久磁石３９ａ、３９ｃを有するようにしたが、永久磁石の数や配置はこれに限定されない。また、永久磁石を電磁石とすることもできる。 In the fishing reel 10 according to the embodiment, the outer ring member 35b of the rotating member 35 has a substantially annular permanent magnet 39b, and the inner ring member 35c has two substantially annular permanent magnets 39a and 39c. However, the number and arrangement of the permanent magnets are not limited to this. In addition, the permanent magnet can be an electromagnet.

一実施形態における魚釣用リール１０では、固定部材３６の外壁部３６ａは、図４に例示したように、スプール３０の回転軸方向の位置が異なる貫通孔３６ｂ１と貫通孔３６ｂ２との大きさ（開口面積、体積）を異なるように形成したが、さらに、外周に沿って形成される複数の貫通孔の外周方向の位置に応じて貫通孔の大きさを異なるようにしてもよい。例えば、図９に例示する変形例の固定部材３６Ｂのように、スプール３０の回転軸方向の２つの位置に外周に沿って複数の貫通孔３６ｂ１、３６ｂ２をそれぞれ形成し、この複数の貫通孔３６ｂ１、３６ｂ２それぞれについて、外周上の特定の位置の貫通孔の大きさを他の貫通孔の大きさよりも大きく（図９の例では、周方向に縦長に）形成しても良い。このように、貫通孔の外周上の位置に応じて貫通孔の大きさを異なるようにすることにより、段階的ではないスムースな制動力の増減調節が可能となる。 In the fishing reel 10 according to the embodiment, as illustrated in FIG. 4, the outer wall portion 36 a of the fixing member 36 has sizes of the through hole 36 b 1 and the through hole 36 b 2 that are different in the position in the rotation axis direction of the spool 30 ( Although the opening area and the volume are different, the sizes of the through holes may be different depending on the positions in the outer peripheral direction of the plurality of through holes formed along the outer periphery. For example, a plurality of through holes 36b1 and 36b2 are formed along the outer periphery at two positions in the rotation axis direction of the spool 30 as in the fixing member 36B of the modification illustrated in FIG. 9, and the plurality of through holes 36b1 are formed. , 36b2 may be formed such that the size of the through hole at a specific position on the outer periphery is larger than the size of the other through holes (in the example of FIG. 9, it is vertically long in the circumferential direction). In this way, by making the size of the through-hole different according to the position on the outer periphery of the through-hole, smooth increase / decrease adjustment of the braking force that is not gradual becomes possible.

一実施形態における魚釣用リール１０では、固定部材３６に貫通孔３６ｂ１、３６ｂ２を形成したが、貫通孔の数、配置は例示したものに限定されない。また、形成される貫通孔の全部又は一部を、貫通しない凹部として形成してもよい。例えば、図１０に例示する変形例の固定部材３６Ｃのように、図２等で例示した一実施形態における固定部材３６の貫通孔３６ｂ２に代えて、回転部材３５の外側リング部材３５ｂ側及び内側リング部材３５ｃ側にそれぞれ開口する２つの凹部３６ｂ３、３６ｂ４を形成してもよい。このように貫通しない凹部３６ｂ３、３６ｂ４であっても、内部に流入するＭＲ流体のせん断応力に基づくドラグ力をスプール３０に対して作用させることができる。こうすることにより、貫通孔とする場合と比較して固定部材３６の剛性を向上させることができる。 In the fishing reel 10 according to the embodiment, the through holes 36b1 and 36b2 are formed in the fixing member 36, but the number and arrangement of the through holes are not limited to those illustrated. Moreover, you may form all or one part of the through-hole formed as a recessed part which does not penetrate. For example, instead of the through hole 36b2 of the fixing member 36 in the embodiment illustrated in FIG. 2 or the like as in the fixing member 36C of the modified example illustrated in FIG. 10, the outer ring member 35b side and the inner ring of the rotating member 35 are replaced. You may form the two recessed parts 36b3 and 36b4 each opened on the member 35c side. Thus, even if it is the recessed part 36b3 and 36b4 which do not penetrate, the drag force based on the shear stress of MR fluid which flows in into an inside can be made to act with respect to the spool 30. FIG. By doing so, the rigidity of the fixing member 36 can be improved as compared with the case of forming the through hole.

一実施形態における魚釣用リール１０では、永久磁石３９を回転部材３５に設けると共に貫通孔３６ｂを固定部材３６に設けたが、これとは逆に、貫通孔を回転部材に設けると共に永久磁石を固定部材に設けてもよい。例えば、本発明の他の実施形態に係る魚釣用リール１００は、図１１に示すように、スプール３０の回転と連動して回転する回転部材３５Ｄと、スプール支持部材３２及び位置調整部材３７を介してスプール軸３１に軸方向移動可能に回り止めされた状態で支持された固定部材３６Ｄとを備える。この回転部材３５Ｄには、貫通孔１３５ｂ１、１３５ｂ２が形成され、固定部材３６Ｄには、永久磁石１３９ａ、１３９ｂ、１３９ｃが設けられている。 In the fishing reel 10 according to the embodiment, the permanent magnet 39 is provided in the rotating member 35 and the through hole 36b is provided in the fixed member 36. Conversely, the through hole is provided in the rotating member and the permanent magnet is provided. You may provide in a fixing member. For example, as shown in FIG. 11, a fishing reel 100 according to another embodiment of the present invention includes a rotation member 35 </ b> D that rotates in conjunction with the rotation of the spool 30, a spool support member 32, and a position adjustment member 37. And a fixing member 36D supported in a state in which the spool shaft 31 is prevented from rotating so as to be axially movable. Through holes 135b1 and 135b2 are formed in the rotating member 35D, and permanent magnets 139a, 139b, and 139c are provided in the fixed member 36D.

より具体的には、回転部材３５Ｄは、前側に開口した略円筒形状を有する円筒部材１３５ｄと、この円筒部材１３５ｄの底部の径方向内側端部からスプール軸３１の軸方向に延びる筒状のスカート部１３５ｅと、この円筒部材１３５ｄの底部のスカート部１３５ｅから径方向に離間した位置に設けられた筒状の壁部１３５ａと、を備える。壁部１３５ａには、複数の貫通孔１３５ｂ１、１３５ｂ２が形成されている。回転部材３５Ｄは、非磁性体の材料からなる。 More specifically, the rotating member 35D includes a cylindrical member 135d having a substantially cylindrical shape opened to the front side, and a cylindrical skirt extending in the axial direction of the spool shaft 31 from the radially inner end of the bottom of the cylindrical member 135d. A portion 135e, and a cylindrical wall portion 135a provided at a position radially spaced from the skirt portion 135e at the bottom of the cylindrical member 135d. A plurality of through holes 135b1 and 135b2 are formed in the wall portion 135a. The rotating member 35D is made of a nonmagnetic material.

また、固定部材３６Ｄは、例えば鉄系の磁性体の材料から成り、略円筒状に構成されている。この固定部材３６Ｄは、スプール軸３１の周方向に延びる外壁部１３６ａと、外壁部１３６ａの前端から径方向内側に延びる略円板形状の底部１３６ｄと、この底部１３６ｄの径方向内側端部からスプール軸３１の軸方向に延びる筒状の内壁部１３６ｃとを有する。また、底部１３６ｄには、外壁部１３６ａと内壁部１３６ｃと略平行に延びる筒状の支持壁１３６ｆが設けられている。 Further, the fixing member 36D is made of, for example, an iron-based magnetic material and has a substantially cylindrical shape. The fixing member 36D includes an outer wall portion 136a extending in the circumferential direction of the spool shaft 31, a substantially disk-shaped bottom portion 136d extending radially inward from the front end of the outer wall portion 136a, and a spool extending from the radially inner end portion of the bottom portion 136d. And a cylindrical inner wall portion 136c extending in the axial direction of the shaft 31. The bottom 136d is provided with a cylindrical support wall 136f extending substantially parallel to the outer wall 136a and the inner wall 136c.

他の実施形態において、外壁部１３６ａの径方向内側には、略円環状の永久磁石１３９ｂが設けられている。スプール軸３１の軸方向において永久磁石１３９ｂの後側には、略円環状の外側リング部材１３６ｂが設けられている。外側リング部材１３６ｂは外壁部１３６ａに嵌め込まれているため、永久磁石１３９ｂは、外壁部１３６ａの内周面に抜け止め固定される。また、支持壁１３６ｆの外周面には、略円環状の永久磁石１３９ａ、１３９ｃが設けられている。支持壁１３６ｆの外周面において、永久磁石１３９ａと永久磁石１３９ｃとの間には、略円環状の第１内側リング１３６ｅが設けられ、永久磁石１３９ｃの後側には第２内側リング１３６ｇが設けられている。このようにして、永久磁石１３９ａ及び永久磁石１３９ｃは、支持壁１３６ｆの外周面に抜け止め固定される。 In another embodiment, a substantially annular permanent magnet 139b is provided on the radially inner side of the outer wall portion 136a. A substantially annular outer ring member 136 b is provided on the rear side of the permanent magnet 139 b in the axial direction of the spool shaft 31. Since the outer ring member 136b is fitted into the outer wall portion 136a, the permanent magnet 139b is secured to the inner peripheral surface of the outer wall portion 136a. Further, substantially annular permanent magnets 139a and 139c are provided on the outer peripheral surface of the support wall 136f. On the outer peripheral surface of the support wall 136f, a substantially annular first inner ring 136e is provided between the permanent magnet 139a and the permanent magnet 139c, and a second inner ring 136g is provided on the rear side of the permanent magnet 139c. ing. In this way, the permanent magnet 139a and the permanent magnet 139c are secured to the outer peripheral surface of the support wall 136f.

上述した外側リング部材１３６ｂ及び永久磁石１３９ｂの内周面と、永久磁石１３９ａ、１３９ｃ、第１内側リング１３６ｅ、及び第２内側リング１３６ｇの外周面と、により、略円筒形状の収容溝１３６ｈが画定される。つまり、外側リング部材１３６ｂ及び永久磁石１３９ｂの内周面は、収容溝１３６ｈの径方向外側の壁を形成し、永久磁石１３９ａ、１３９ｃ、第１内側リング１３６ｅ、及び第２内側リング１３６ｇの外周面は、収容溝１３６ｈの径方向内側の壁を形成する。この収容溝１３６ｈの前端は底部１３６ｄにより閉塞されているが、後端は開口している。収容溝１３６ｈには、不図示のＭＲ流体が収容される。こうした構成においても、一実施形態における魚釣用リール１０と同様に、ＭＲ流体のせん断応力に応じてスプール３０に制動力を作用させることができる。 A substantially cylindrical accommodation groove 136h is defined by the inner peripheral surfaces of the outer ring member 136b and the permanent magnet 139b and the outer peripheral surfaces of the permanent magnets 139a and 139c, the first inner ring 136e, and the second inner ring 136g. Is done. That is, the inner peripheral surfaces of the outer ring member 136b and the permanent magnet 139b form a radially outer wall of the receiving groove 136h, and the outer peripheral surfaces of the permanent magnets 139a and 139c, the first inner ring 136e, and the second inner ring 136g. Forms the radially inner wall of the receiving groove 136h. The front end of the housing groove 136h is closed by the bottom 136d, but the rear end is open. An MR fluid (not shown) is accommodated in the accommodation groove 136h. Even in such a configuration, a braking force can be applied to the spool 30 in accordance with the shear stress of the MR fluid, similarly to the fishing reel 10 in the embodiment.
