The multiple first through-holes 38 are opened at a radial direction position of a third distance R3 not more than a second distance R2 of 60% of a first distance R1 from an outer circumferential surface of the spool body 32 to the outer circumferential surface of the flange 34, and are spaced apart in the circumferential direction to the flanges 34.SELECTED DRAWING: Figure 3

Description

本発明は、スプール、特に、両軸受リールのスプールに関する。 The present invention relates to spools, and in particular to dual bearing reel spools.

両軸受リールのスプールには、フランジ部に周方向に間隔を隔てて配置された複数の貫通孔を設けたものが知られている（特許文献１参照）。貫通孔をフランジ部に設けることによって、スプールの外径を小さくすることなく、スプールの質量及び慣性を低減できる。 A spool of a dual-bearing reel is known in which a plurality of through holes are provided in a flange portion at intervals in the circumferential direction (see Patent Document 1). By providing the through hole in the flange portion, the mass and inertia of the spool can be reduced without reducing the outer diameter of the spool.

特開平１０−１６５０５７号公報Japanese Patent Laid-Open No. 10-165057

従来のスプールでは、キャスティング時にスプールが高速で糸繰り出し方向に回転したとき、空気が貫通孔を通過し、風切り音などの異音が発生することがある。 In the conventional spool, when the spool rotates at a high speed in the yarn feeding direction at the time of casting, air may pass through the through hole, and abnormal noise such as wind noise may be generated.

本発明の課題は、質量及び慣性の低減を図ったスプールにおいて、スプールが高速回転したときの異音の発生を抑えることにある。 An object of the present invention is to suppress the generation of abnormal noise when the spool rotates at a high speed in a spool having a reduced mass and inertia.

本発明に係る両軸受リールのスプールは、筒状の糸巻き胴部と、一対の円形のフランジ部と、複数の第１貫通孔と、を備える。一対の円形のフランジ部は、糸巻き胴部の両端に糸巻き胴部よりも大径に形成される。複数の第１貫通孔は、最大糸巻き長さの半分の糸巻き長さの釣り糸によって覆われるように、フランジ部に周方向に間隔を隔てて配置される。 The spool of the dual bearing reel according to the present invention includes a tubular bobbin trunk, a pair of circular flanges, and a plurality of first through holes. The pair of circular flange portions are formed on both ends of the bobbin trunk with a diameter larger than that of the bobbin trunk. The plurality of first through holes are arranged in the flange portion at intervals in the circumferential direction so that the first through holes are covered with the fishing line having a line winding length that is half the maximum line winding length.

この両軸受リールのスプールでは、複数の第１貫通孔が、最大糸巻き長さの半分の糸巻き長さの釣り糸によって覆われるように、フランジ部に周方向に間隔を隔てて配置される。通常のキャスティングでは、最大でおおむね最大糸巻き長さの半分の長さの釣り糸が繰り出される。このため、キャスティング中に第１貫通孔が露出されなくなり、キャスティングときに、第１貫通孔が釣り糸によって塞がれて外部に露出しない。このため、キャスティング時にスプールが高速回転しても、異音の発生を抑えることができる。 In the spool of the dual bearing reel, the plurality of first through holes are arranged in the flange portion at intervals in the circumferential direction so that the first through holes are covered with the fishing line having a line winding length which is half the maximum line winding length. In normal casting, the maximum length of the fishing line is about half the maximum length of the wound line. Therefore, the first through hole is not exposed during casting, and the first through hole is blocked by the fishing line and is not exposed to the outside during casting. Therefore, even if the spool rotates at high speed during casting, it is possible to suppress the generation of abnormal noise.

第１貫通孔の少なくとも糸巻き胴部の外周面に近い側の周縁部には面取り部が設けられてもよい。この構成によれば、面取り部によって空気の流速の変化が小さくなり、異音の発生をさらに抑えることができる。 A chamfer may be provided on at least the peripheral edge of the first through hole that is closer to the outer peripheral surface of the bobbin trunk. With this configuration, the chamfer reduces the change in the flow velocity of the air, and can further suppress the generation of abnormal noise.

面取り部は、糸巻胴部の端部まで延びていてもよい。 The chamfer may extend to the end of the bobbin trunk.

本発明によれば、質量及び慣性の低減を図ったスプールにおいて、スプールが高速回転したときの異音の発生を抑えることができる。 According to the present invention, in a spool with reduced mass and inertia, it is possible to suppress the generation of abnormal noise when the spool rotates at high speed.

＜両軸受リールの全体構成＞
図１及び図２において、本発明の一実施形態によるスプール１６を採用した両軸受リール１０は、釣り糸を前方に繰り出すリールである。両軸受リール１０は、リール本体１２と、ハンドル１４と、ハンドル１４によって糸巻き取り方向に回転するスプール１６と、スプール軸１８（図２参照）と、を備える。ハンドル１４は、リール本体１２の側部に回転自在に装着される。 <Overall structure of dual bearing reel>
1 and 2, a dual bearing reel 10 that employs a spool 16 according to an embodiment of the present invention is a reel that delivers fishing line forward. The dual-bearing reel 10 includes a reel body 12, a handle 14, a spool 16 that rotates in the yarn winding direction by the handle 14, and a spool shaft 18 (see FIG. 2 ). The handle 14 is rotatably attached to the side portion of the reel body 12.

図１に示すように、リール本体１２は、フレーム１２ａと、フレーム１２ａの両側方を覆う第１側カバー１２ｂ及び第２側カバー１２ｃと、を有する。リール本体１２は、スプール軸１８及びスプール１６のいずれか一方を回転自在に支持する。本実施形態では、リール本体１２はスプール軸１８を回転自在に支持する。 As shown in FIG. 1, the reel body 12 has a frame 12a, and a first side cover 12b and a second side cover 12c that cover both sides of the frame 12a. The reel unit 12 rotatably supports one of the spool shaft 18 and the spool 16. In the present embodiment, the reel body 12 rotatably supports the spool shaft 18.

リール本体１２の内部には、回転伝達機構２０、クラッチ機構２２、ドラグ機構（図示せず）、キャスティングコントロール機構２４、及びスプール制動機構２６が設けられる。回転伝達機構２０は、ハンドル１４の回転をスプール１６に伝達する。クラッチ機構２２は、回転伝達機構２０の伝達経路の途中に設けられる。クラッチ機構２２は、ハンドル１４の回転をスプール１６に伝達する伝達状態と、ハンドル１４の回転を遮断する遮断状態と、に切換可能である。遮断状態では、スプール１６は自由回転状態になる。クラッチ機構２２は、リール本体１２に設けられるクラッチ操作部材２８によって伝達状態と遮断状態に操作できる。本実施形態では、クラッチ操作部材２８は、スプール１６の後方に上下に移動自在に設けられる。ドラグ機構は、釣り糸に作用する張力（ドラグ力）を調整するために回転伝達経路の途中に設けられる。ドラグ機構のドラグ力は、ハンドル１４に軸方向に並べて配置されたドラグ操作部材３０によって調整できる。キャスティングコントロール機構２４は、スプール軸１８の両端を押圧してスプール１６を常時制動する。スプール制動機構２６は、キャスティング時にスプール１６の糸繰り出し方向の回転を制動する。スプール制動機構は、遠心力、磁力、または回生制動によってスプール１６を制動する。本実施形態では、スプール制動機構２６は遠心力によって、スプール１６を制動する。 A rotation transmission mechanism 20, a clutch mechanism 22, a drag mechanism (not shown), a casting control mechanism 24, and a spool braking mechanism 26 are provided inside the reel body 12. The rotation transmission mechanism 20 transmits the rotation of the handle 14 to the spool 16. The clutch mechanism 22 is provided in the transmission path of the rotation transmission mechanism 20. The clutch mechanism 22 can be switched between a transmission state in which the rotation of the handle 14 is transmitted to the spool 16 and a disconnection state in which the rotation of the handle 14 is blocked. In the cutoff state, the spool 16 is in a free rotation state. The clutch mechanism 22 can be operated in a transmission state and a disengaged state by a clutch operating member 28 provided on the reel body 12. In the present embodiment, the clutch operating member 28 is provided behind the spool 16 so as to be vertically movable. The drag mechanism is provided in the middle of the rotation transmission path in order to adjust the tension (drag force) acting on the fishing line. The drag force of the drag mechanism can be adjusted by the drag operating member 30 arranged on the handle 14 in the axial direction. The casting control mechanism 24 presses both ends of the spool shaft 18 to constantly brake the spool 16. The spool braking mechanism 26 brakes the rotation of the spool 16 in the yarn feeding direction during casting. The spool braking mechanism brakes the spool 16 by centrifugal force, magnetic force, or regenerative braking. In this embodiment, the spool braking mechanism 26 brakes the spool 16 by centrifugal force.

＜スプール及びスプール軸の構成＞
スプール１６は、図３及び図４に示すように、スプール軸１８に一体回転可能に連結される。スプール１６は、筒状の糸巻き胴部３２と、糸巻き胴部３２の両端に形成された一対のフランジ部３４と、糸巻き胴部３２の内周面に形成された連結部３６と、複数の第１貫通孔３８と、複数の第２貫通孔４０と、を有する。 <Structure of spool and spool shaft>
As shown in FIGS. 3 and 4, the spool 16 is integrally rotatably connected to a spool shaft 18. The spool 16 includes a tubular bobbin trunk 32, a pair of flanges 34 formed at both ends of the bobbin trunk 32, a connecting portion 36 formed on an inner peripheral surface of the bobbin trunk 32, and a plurality of first and second spools. It has one through hole 38 and a plurality of second through holes 40.

糸巻き胴部３２は、外周面に釣り糸を巻き付け可能である。本実施形態では、糸巻き胴部３２は、スプール軸１８の軸芯ＳＣからの距離が軸方向の中心位置ＣＰで最も小さくとなるように、両端からわずかに傾斜した第１テーパ面３２ａおよび第２テーパ面３２ｂを有する。本実施形態では、糸巻き胴部３２の外周面は中心位置ＣＰでの外周面である。 The fishing line winding body 32 is capable of winding fishing line on the outer peripheral surface thereof. In the present embodiment, the bobbin trunk 32 has the first taper surface 32a and the second taper surface 32a slightly inclined from both ends so that the distance from the axial center SC of the spool shaft 18 becomes the smallest at the center position CP in the axial direction. It has a tapered surface 32b. In the present embodiment, the outer peripheral surface of the bobbin trunk 32 is the outer peripheral surface at the center position CP.

一対のフランジ部３４は、厚みが、径方向外側から径方向内側に向かって徐々に厚くなるように構成される。一対のフランジ部３４は、スプール１６の軸方向の中心位置ＣＰに対して線対称に形成される。一対のフランジ部３４は、最大巻き付け位置の目安となる第３テーパ面３４ａと、第３テーパ面３４ａの外周部に形成された糸かみ防止用の筒状部３４ｂと、をそれぞれ有する。第３テーパ面３４ａは、軸方向の中心位置ＣＰに向かって小径となるように傾斜するテーパ面である。図３に拡大して示すように、第３テーパ面３４ａの内周側の環状の縁部３４ｃが最大巻き付け位置の目安となる。フランジ部３４の外周面は、筒状部３４ｂの外周面である。 The pair of flange portions 34 is configured such that the thickness gradually increases from the radially outer side toward the radially inner side. The pair of flange portions 34 are formed line-symmetrically with respect to the axial center position CP of the spool 16. The pair of flange portions 34 each have a third taper surface 34a that serves as a guide for the maximum winding position, and a tubular portion 34b that is formed on the outer peripheral portion of the third taper surface 34a and that prevents thread catching. The third tapered surface 34a is a tapered surface that inclines so as to have a small diameter toward the center position CP in the axial direction. As shown in an enlarged manner in FIG. 3, the annular edge 34c on the inner peripheral side of the third tapered surface 34a serves as a guide for the maximum winding position. The outer peripheral surface of the flange portion 34 is the outer peripheral surface of the tubular portion 34b.

連結部３６は、糸巻き胴部３２の内周面に一体形成される円板部３６ａと、円板部の内周部に一体形成された装着筒部３６ｂと、を有する。装着筒部３６ｂは、例えば、スプール軸１８の外周面に形成されたセレーション部１８ａが圧入されることによって、スプール軸１８と一体回転可能に連結される。 The connecting portion 36 has a disc portion 36a that is integrally formed on the inner peripheral surface of the bobbin trunk portion 32, and a mounting cylinder portion 36b that is integrally formed on the inner peripheral portion of the disc portion. The mounting cylinder portion 36b is integrally rotatably connected to the spool shaft 18 by press-fitting a serration portion 18a formed on the outer peripheral surface of the spool shaft 18, for example.

複数の第１貫通孔３８は、本実施形態では、図５に示すように、糸巻き胴部３２の外周面からフランジ部３４の外周面までの第１距離Ｒ１の６０パーセントの第２距離Ｒ２以下の第３距離Ｒ３の径方向位置で開口する。複数の第１貫通孔３８は、周方向に間隔を隔てて、例えば１２個設けられる。複数の第１貫通孔３８の個数は１２個に限定されない。複数の第１貫通孔３８は、回転バランス及び強度を考慮して配置される。第１貫通孔３８の個数は、例えば６個から２０個が好ましい。第１貫通孔３８の個数が５個以下であると、軽量化及び低慣性化を図ろうとすると、第１貫通孔の直径が大きくなる。また、第１貫通孔３８の個数が２１個以上であると、加工コストが上昇し、かつフランジ部３４の強度が低くなる。第１貫通孔３８は、中心Ｃが第３距離の径方向位置よりも糸巻き胴部３２の外周面に近い位置にある円形の孔である。第１貫通孔３８は、図３に拡大して示すように、円形の孔部３８ａと、孔部３８ａのフランジ部３４の内側面３４ｄの糸巻き胴部３２の少なくとも外周面に近い側の周縁部に設けられた面取り部３８ｂと、を有する。なお、第１貫通孔３８の開口する位置は、面取り部３８ｂではなく、孔部３８ａによって規定される。また、本実施形態では、面取り部３８ｂは、例えばテーパ面形状に形成され、周縁部の全周に設けられる。 In the present embodiment, as shown in FIG. 5, the plurality of first through holes 38 are the second distance R2 or less, which is 60% of the first distance R1 from the outer peripheral surface of the bobbin trunk 32 to the outer peripheral surface of the flange portion 34. The opening is made at the radial position of the third distance R3. For example, twelve first through holes 38 are provided at intervals in the circumferential direction. The number of the plurality of first through holes 38 is not limited to twelve. The plurality of first through holes 38 are arranged in consideration of rotation balance and strength. The number of the first through holes 38 is preferably 6 to 20, for example. If the number of the first through holes 38 is 5 or less, the diameter of the first through holes becomes large in order to reduce the weight and the inertia. If the number of the first through holes 38 is 21 or more, the processing cost increases and the strength of the flange portion 34 decreases. The first through hole 38 is a circular hole whose center C is closer to the outer peripheral surface of the bobbin trunk 32 than the radial position at the third distance. As shown in an enlarged scale in FIG. 3, the first through hole 38 has a circular hole portion 38a and a peripheral edge portion of the inner side surface 34d of the flange portion 34 of the hole portion 38a at least near the outer peripheral surface of the bobbin trunk 32. And a chamfered portion 38b provided on the. The opening position of the first through hole 38 is defined not by the chamfered portion 38b but by the hole portion 38a. Further, in the present embodiment, the chamfered portion 38b is formed, for example, in a tapered surface shape and is provided on the entire circumference of the peripheral edge portion.

図４に示すように、複数の第２貫通孔４０は、糸巻き胴部３２の外周面と内周面とを貫通する。本実施形態では、第２貫通孔４０は、図３に示すように、軸方向の中心位置ＣＰを中心とする円によって構成される。第２貫通孔４０は、軸方向に沿って延びる、図示しない楕円状の面取り部が角部に形成される。 As shown in FIG. 4, the plurality of second through holes 40 penetrate the outer peripheral surface and the inner peripheral surface of the bobbin trunk 32. In the present embodiment, as shown in FIG. 3, the second through hole 40 is formed by a circle centered on the axial center position CP. The second through hole 40 has an elliptical chamfered portion (not shown) formed in a corner portion extending in the axial direction.

このように構成されたスプール１６では、キャスティング時に、フランジ部３４の外周部まで巻き付けられた釣り糸が放出されると、概ね全体の半分の長さの釣り糸が放出されるまで、第１貫通孔３８が釣り糸によって塞がれて露出しない。このため、キャスティング初期の高速回転時に空気が第１貫通孔３８を通過しない。これによって、キャスティング時に、空気の流れに伴う異音の発生を抑えることができる。 In the spool 16 configured as described above, when the fishing line wound up to the outer peripheral portion of the flange portion 34 is released during casting, the first through hole 38 is formed until the fishing line of approximately half the entire length is released. Is blocked by fishing line and is not exposed. For this reason, air does not pass through the first through hole 38 at the time of high speed rotation in the initial stage of casting. As a result, it is possible to suppress the generation of abnormal noise due to the flow of air during casting.

＜第１から第３変形例＞
なお、以降の説明では、上記実施形態と同じ構成の部材は同じ符号で図に示し、その説明を省略する。また、構成は異なるが対応する部材には、上記実施形態と下二桁が同じ三桁の符号で示す。 <First to Third Modifications>
In the following description, members having the same configurations as those of the above-described embodiment are designated by the same reference numerals in the drawings, and the description thereof will be omitted. Further, corresponding members having different configurations are indicated by the same three-digit symbols as the last two digits which are the same as those in the above-described embodiment.

上記実施形態では、第１貫通孔３８の孔部３８ａが円形であったが、第１貫通孔の孔部の形状は、円形に限定されない。例えば、図６に示す第１変形例では、スプール１１６の第１貫通孔１３８の孔部１３８ａは、径方向に長い長円形の孔である。また、図７に示す第２変形例では、スプール２１６の第１貫通孔２３８の孔部２３８ａは、周方向に長い長円形の孔である。さらに、図８に示す第３変形例では、スプール３１６の第１貫通孔３３８の孔部３３８ａは、円形ではなく、多角形の孔である。第１から第３変形例の場合にも、図９に示すように、例えば、第１貫通孔１３８（又は、２３８，３３８）は、糸巻き胴部３２の外周面からフランジ部３４の外周面までの第１距離Ｒ１の６０パーセントの第２距離Ｒ２以下の第３距離Ｒ３の径方向位置で開口するように配置される。また、面取り部１３８ｂ（又は、２３８ｂ、３３８ｂ）は、上記実施形態と同様に、例えばテーパ面形状に形成され、周縁部の全周に設けられる。 Although the hole portion 38a of the first through hole 38 is circular in the above-described embodiment, the shape of the hole portion of the first through hole is not limited to a circle. For example, in the first modification shown in FIG. 6, the hole portion 138a of the first through hole 138 of the spool 116 is an oval hole that is long in the radial direction. Further, in the second modification shown in FIG. 7, the hole portion 238a of the first through hole 238 of the spool 216 is an oval hole that is long in the circumferential direction. Further, in the third modified example shown in FIG. 8, the hole portion 338a of the first through hole 338 of the spool 316 is a polygonal hole rather than a circular hole. Also in the case of the first to third modified examples, as shown in FIG. 9, for example, the first through hole 138 (or 238, 338) extends from the outer peripheral surface of the bobbin trunk 32 to the outer peripheral surface of the flange 34. The first distance R1 is 60% of the second distance R2 and the third distance R3 is less than or equal to the third distance R3. Further, the chamfered portion 138b (or 238b, 338b) is formed in, for example, a tapered surface shape, and is provided on the entire circumference of the peripheral portion, as in the above embodiment.

＜第４変形例＞
図１０及び図１１に示す第４変形例では、第１貫通孔４３８の孔部４３８ａは、円形であり、面取り部４３８ｂは、周縁部の糸巻き胴部３２の外周面に近い側に設けられる。面取り部４３８ｂは、例えば、中心Ｄを中心に回転する球形の切削工具Ｇによって，糸巻き胴部３２の外周面に近い側だけを糸巻き胴部３２とともに機械加工して球面状に形成される。 <Fourth Modification>
In the fourth modification shown in FIGS. 10 and 11, the hole portion 438a of the first through hole 438 is circular, and the chamfered portion 438b is provided on the peripheral portion on the side close to the outer peripheral surface of the bobbin trunk 32. The chamfered portion 438b is formed into a spherical shape by machining only the side close to the outer peripheral surface of the bobbin trunk 32 together with the bobbin trunk 32 with a spherical cutting tool G that rotates around the center D, for example.

このように形成された面取り部４３８ｂでは、外周部に向かって肉厚が徐々に薄くなるフランジ部４３４に第１貫通孔４３８を形成しても、糸巻き胴部３２から遠い側に面取り部が形成されない。このため、フランジ部４３４の強度を維持できる。 In the chamfered portion 438b formed in this manner, even if the first through hole 438 is formed in the flange portion 434 where the wall thickness gradually decreases toward the outer peripheral portion, the chamfered portion is formed on the side far from the bobbin trunk 32. Not done. Therefore, the strength of the flange portion 434 can be maintained.

＜他の実施形態＞
以上、本発明の一実施形態及びその変形例について説明したが、本発明は上記実施形態及び変形例に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。特に、本明細書に書かれた実施形態及び複数の変形例は必要に応じて任意に組合せ可能である。 <Other Embodiments>
Although one embodiment of the present invention and its modification have been described above, the present invention is not limited to the above embodiment and modification, and various modifications can be made without departing from the spirit of the invention. In particular, the embodiments and plural modifications described in this specification can be arbitrarily combined as needed.

（ａ）上記実施形態では、第１貫通孔３８を周方向に間隔を隔てて配置したが、本発明はこれに限定されない。例えば、第１貫通孔を周方向及び径方向に間隔を隔てて配置してもよい。この場合、最外周の第１貫通孔が、糸巻き胴部３２の外周面からフランジ部３４の外周面までの第１距離Ｒ１の６０パーセントの第２距離Ｒ２以下の第３距離Ｒ３の径方向位置で開口すればよい。 (A) In the above embodiment, the first through holes 38 are arranged at intervals in the circumferential direction, but the present invention is not limited to this. For example, the first through holes may be arranged at intervals in the circumferential direction and the radial direction. In this case, the outermost first through hole has a radial position of a third distance R3 that is less than or equal to a second distance R2 that is 60% of the first distance R1 from the outer peripheral surface of the bobbin trunk 32 to the outer peripheral surface of the flange portion 34. Open with.

（ｂ）上記実施形態では、第１貫通孔３８の配置を開口する位置で定義したが、本発明はこれに限定されない。第１貫通孔３８は、キャスティング当初の高速回転時に釣り糸によって塞がれて開口しない位置であれば、どのように配置されてもよい。例えば、最大糸巻き長さの半分の糸巻き長さの釣り糸によって覆われるように、フランジ部３４に周方向に間隔を隔てて、第１貫通孔３８を配置してもよい。通常の形状のスプール１６であれば、この位置は、上述した、糸巻き胴部３２の外径からフランジ部３４の外径までの距離の概ね６０パーセントの径方向位置である。 (B) In the above embodiment, the arrangement of the first through holes 38 is defined as the opening position, but the present invention is not limited to this. The first through hole 38 may be arranged in any position as long as it is a position that is blocked by the fishing line and does not open at the time of high speed rotation at the beginning of casting. For example, the first through holes 38 may be arranged in the flange portion 34 at intervals in the circumferential direction so that the first through holes 38 are covered with the fishing line having a fishing line length that is half the maximum fishing line winding length. In the case of the spool 16 having a normal shape, this position is a radial position of approximately 60% of the above-described distance from the outer diameter of the bobbin trunk portion 32 to the outer diameter of the flange portion 34.

（ｃ）上記実施形態および第１から第３変形例では、面取り部を第１貫通孔の周縁部の全周に形成したが、第４変形例と同様に周縁部の糸巻き胴部の外周面に近い側にだけ形成してもよい。 (C) In the above-described embodiment and the first to third modified examples, the chamfered portion is formed on the entire circumference of the peripheral portion of the first through hole, but like the fourth modified example, the outer peripheral surface of the bobbin trunk at the peripheral portion is formed. It may be formed only on the side close to.

（ｄ）上記実施形態では、スプール制動機構２６が遠心力によって、スプール１６を制動した。しかし、図１２に示すように、スプール制動機構５２６が、スプール軸５１８に一体回転可能に連結された磁石５４２と、磁石５４２の回転により発電するコイル５４４とを含む発電制動機構でもよい。この場合には、スプール５１６の糸巻き胴部５３２の内周面に磁束漏洩防止用の筒状部材５４６を装着できる環状凹部５３２ｃを形成してもよい。
＜特徴＞
上記実施形態は、下記のように表現可能である。 (D) In the above embodiment, the spool braking mechanism 26 brakes the spool 16 by the centrifugal force. However, as shown in FIG. 12, the spool braking mechanism 526 may be a dynamic braking mechanism including a magnet 542 that is integrally rotatably connected to the spool shaft 518, and a coil 544 that generates electricity by the rotation of the magnet 542. In this case, an annular recess 532c may be formed on the inner peripheral surface of the bobbin trunk 532 of the spool 516, in which a tubular member 546 for preventing magnetic flux leakage can be mounted.
<Features>
The above embodiment can be expressed as follows.

（Ａ）両軸受リール１０のスプール１６は、筒状の糸巻き胴部３２と、一対の円形のフランジ部３４と、複数の第１貫通孔３８と、を備える。一対の円形のフランジ部３４は、糸巻き胴部３２の両端に糸巻き胴部３２よりも大径に形成される。複数の第１貫通孔３８は、糸巻き胴部３２の外周面からフランジ部３４の外周面までの第１距離Ｒ１の６０パーセントの第２距離Ｒ２以下の第３距離Ｒ３の径方向位置で開口し、フランジ部３４に周方向に間隔を隔てて配置される。 (A) The spool 16 of the dual-bearing reel 10 includes a cylindrical bobbin trunk 32, a pair of circular flanges 34, and a plurality of first through holes 38. The pair of circular flange portions 34 are formed on both ends of the bobbin trunk 32 with a diameter larger than that of the bobbin trunk 32. The plurality of first through holes 38 are opened at a radial position of a third distance R3 that is less than or equal to a second distance R2 that is 60% of the first distance R1 from the outer peripheral surface of the bobbin trunk 32 to the outer peripheral surface of the flange portion 34. , Are arranged in the flange portion 34 at intervals in the circumferential direction.

この両軸受リール１０のスプール１６では、複数の第１貫通孔３８が、糸巻き胴部３２外周面からフランジ部３４の外周面までの第１距離Ｒ１の６０パーセントの第２距離Ｒ２以下の第３距離Ｒ３の径方向位置で開口するように配置される。このため、キャスティングの速度が最も速いキャスティングの初期に、第１貫通孔３８が釣り糸によって塞がれて外部に露出しない。このため、空気が第１貫通孔３８を通過しなくなり、キャスティング時にスプール１６が高速回転しても、異音の発生を抑えることができる。 In the spool 16 of the dual-bearing reel 10, the plurality of first through holes 38 have the third distance equal to or less than the second distance R2 which is 60% of the first distance R1 from the outer peripheral surface of the bobbin trunk portion 32 to the outer peripheral surface of the flange portion 34. It is arranged so as to open at a radial position of a distance R3. For this reason, the first through hole 38 is blocked by the fishing line and is not exposed to the outside at the beginning of casting at the highest casting speed. Therefore, air does not pass through the first through hole 38, and even if the spool 16 rotates at high speed during casting, it is possible to suppress the generation of abnormal noise.

（Ｂ）第１貫通孔３８は、中心Ｃが径方向位置よりも糸巻き胴部３２の外周面に近い位置にある円形の孔であってもよい。この構成によれば、機械加工または成形加工によって第１貫通孔３８を容易に形成できる。 (B) The first through hole 38 may be a circular hole whose center C is closer to the outer peripheral surface of the bobbin trunk 32 than its radial position. With this configuration, the first through hole 38 can be easily formed by machining or molding.

（Ｃ）第１貫通孔１３８は、径方向に長い長円形の孔であってもよい。この構成によれば、円形と同じ肉盗み量であっても、長円形の孔は、移動方向に対する貫通孔の幅を短くすることができる。このため、貫通孔を通過する空気の量を減らして風切音の発生をさらに抑制できる。 (C) The first through hole 138 may be an oval hole that is long in the radial direction. According to this configuration, the oval hole can reduce the width of the through hole with respect to the moving direction even if the thickness of the hole is the same as the circular shape. Therefore, the amount of air passing through the through hole can be reduced to further suppress the generation of wind noise.

（Ｄ）フランジ部３４は、厚みが径方向外側から径方向内側に向かって徐々に厚くなるように構成されてもよい。この構成によれば、糸巻き胴部３２側の肉厚が徐々に厚くなるので、糸巻き胴部３２に近い位置に第１貫通孔３８を形成しても、フランジ部３４の強度の低下を抑えることができる。 (D) The flange portion 34 may be configured such that the thickness gradually increases from the radially outer side toward the radially inner side. According to this configuration, since the wall thickness on the bobbin trunk 32 side gradually increases, even if the first through hole 38 is formed at a position close to the bobbin trunk 32, the strength of the flange portion 34 is prevented from decreasing. You can

（Ｅ）第１貫通孔３８の少なくとも糸巻き胴部の外周面に近い側の周縁部には面取り部が設けられてもよい。この構成によれば、面取り部によって空気の流速の変化が小さくなり、異音の発生をさらに抑えることができる。 (E) A chamfer may be provided at least on the peripheral edge of the first through hole 38 on the side closer to the outer peripheral surface of the bobbin trunk. With this configuration, the chamfer reduces the change in the flow velocity of the air, and can further suppress the generation of abnormal noise.

（Ｆ）スプール１６は、糸巻き胴部３２の外周面と内周面とを貫通する第２貫通孔４０をさらに備えてもよい。この構成によれば、スプール１６のさらなる軽量化及び低慣性化を図れる。 (F) The spool 16 may further include a second through hole 40 that penetrates the outer peripheral surface and the inner peripheral surface of the bobbin trunk 32. With this configuration, the spool 16 can be further reduced in weight and inertia.

（Ｇ）両軸受リール１０のスプール１６は、筒状の糸巻き胴部３２と、一対の円形のフランジ部３４と、複数の第１貫通孔３８と、を備える。一対の円形のフランジ部３４は、糸巻き胴部３２の両端に糸巻き胴部よりも大径に形成される。複数の第１貫通孔３８は、最大糸巻き長さの半分の糸巻き長さの釣り糸によって覆われるように、フランジ部３４に周方向に間隔を隔てて配置される。 (G) The spool 16 of the dual-bearing reel 10 includes a tubular bobbin trunk 32, a pair of circular flanges 34, and a plurality of first through holes 38. The pair of circular flange portions 34 are formed on both ends of the bobbin trunk 32 with a diameter larger than that of the bobbin trunk. The plurality of first through holes 38 are arranged in the flange portion 34 at intervals in the circumferential direction so that the first through holes 38 are covered with the fishing line having a line winding length that is half the maximum line winding length.

この両軸受リールのスプール１６では、複数の第１貫通孔３８が、最大糸巻き長さの半分の糸巻き長さの釣り糸によって覆われるように、フランジ部３４に周方向に間隔を隔てて配置される。通常のキャスティングでは、最大でおおむね最大糸巻き長さの半分の長さの釣り糸が繰り出される。このため、キャスティング中に第１貫通孔３８が露出されなくなり、キャスティングときに、第１貫通孔３８が釣り糸によって塞がれて外部に露出しない。このため、キャスティング時にスプール１６が高速回転しても、異音の発生を抑えることができる。 In the spool 16 of the dual-bearing reel, the plurality of first through holes 38 are arranged in the flange portion 34 at intervals in the circumferential direction so that the first through holes 38 are covered with the fishing line having a fishing line length which is half the maximum fishing line length. .. In normal casting, the maximum length of the fishing line is about half the maximum length of the wound line. Therefore, the first through hole 38 is not exposed during casting, and during casting, the first through hole 38 is blocked by the fishing line and is not exposed to the outside. Therefore, even if the spool 16 rotates at high speed during casting, it is possible to suppress the generation of abnormal noise.
