そして、回転軸筒３１の後端側外周に設けられたピニオン４１に、ハンドル４３のハンドル軸４５に回り止め嵌着した駆動歯車４７が噛合しており、ハンドル４３の回転操作（巻取り操作）が駆動歯車４７，ピニオン４１から回転軸筒３１に伝達されて、ロータ３７が釣糸巻取り方向へ回転するようになっている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a spinning reel according to a first embodiment of claims 1 and 2, in which 31 is a hollow rotating shaft cylinder rotatably supported by a front portion of a reel body 35 via a bearing 33. (Flyer shaft), the rotor 37 is fixed to the tip thereof with a nut 39.
Then, a drive gear 47 that is non-rotatably fitted to the handle shaft 45 of the handle 43 is meshed with a pinion 41 provided on the outer periphery of the rear end side of the rotary shaft cylinder 31, and a rotation operation (winding operation) of the handle 43 is engaged. Is transmitted from the drive gear 47 and the pinion 41 to the rotary shaft 31 so that the rotor 37 rotates in the fishing line winding direction.

円筒状に形成されたロータ３７の基部には、一対の支持アーム４９が前方へ向けて一体に延設されており、両支持アーム４９の先端に、支持部材５１が釣糸巻取り位置と釣糸放出位置とに反転自在に取り付けられている。そして、両支持部材５１間に半環状のベール５３が取り付き、一方のベール支持部材５１にラインローラ（釣糸案内部）５５が回転可能に装着されている。   A pair of support arms 49 are integrally extended forward at the base of the rotor 37 formed in a cylindrical shape, and a support member 51 is attached to the tip of both support arms 49 at the position where the fishing line is wound and the fishing line is released. It is attached to the position so that it can be reversed. A semi-annular bail 53 is attached between the support members 51, and a line roller (fishing line guide portion) 55 is rotatably attached to one bail support member 51.

また、図中、５７は回転軸筒３１内を挿通してリール本体３５の前後方向に摺動可能に支持されたスプール軸で、スプール軸５７のロータ側突出端にスプール５９がドラグノブ６１を介して取り付き、スプール軸５７の後端側に、周知のトラバース機構（スプール往復動装置）６３の摺動子６５が連結されている。
而して、スプール５９は、釣糸を巻回する釣糸巻回胴部６７と、その前方に設けられて釣糸巻回胴部６７の外径より大径な前側フランジ部６９と、釣糸巻回胴部６７の後方に設けられた大径な円筒状のスカート部７１とで構成されており、図２に示すようにスカート部７１の外周は支持アーム４９の内周に対向している。 In the figure, reference numeral 57 denotes a spool shaft that is inserted into the rotary shaft cylinder 31 and supported so as to be slidable in the front-rear direction of the reel body 35. A spool 59 is provided on the rotor-side protruding end of the spool shaft 57 via a drag knob 61. A slider 65 of a known traverse mechanism (spool reciprocating device) 63 is connected to the rear end side of the spool shaft 57.
Thus, the spool 59 includes a fishing line winding body portion 67 for winding the fishing line, a front flange portion 69 provided in front of the fishing line winding body portion 67 and having a diameter larger than the outer diameter of the fishing line winding body portion 67, and a fishing line winding body. The outer periphery of the skirt portion 71 is opposed to the inner periphery of the support arm 49 as shown in FIG.

そして、従来と同様、ベール５３を釣糸放出位置へ倒して仕掛けをキャスティングすると、釣糸巻回胴部６７に巻回された釣糸がスパイラル状に繰り出され、また、ベール５３を釣糸巻取位置側へ倒してハンドル４３を巻取り操作すると、ロータ３７の回転に連動してトラバース機構６３により前後方向へ往復動するスプール５９（釣糸巻回胴部６７）に、釣糸がラインローラ５５を介して巻回されるようになっている。   Then, as before, when the bale 53 is tilted to the fishing line discharge position and the device is cast, the fishing line wound around the fishing line winding body 67 is drawn out in a spiral shape, and the bale 53 is moved to the fishing line winding position side. When the handle 43 is wound up and the handle 43 is wound up, the fishing line is wound around the spool 59 (fishing line winding body 67) reciprocated in the front-rear direction by the traverse mechanism 63 in conjunction with the rotation of the rotor 37 via the line roller 55. It has come to be.

更に、前記回転軸筒３１の略中間部分の外周には、キャスティング時や釣糸の巻取り操作時にハンドル４３の逆回転を阻止する一方向クラッチ７３を用いた周知の逆転防止機構７５が装着されており、リール本体３５の後部側に逆転防止機構７５の切換えレバー７７が装着されている。
そして、図７に示す従来例と同様、本実施形態に係るスピニングリール７９も、上述の如き構成に加え、スプール５９内部やロータ３７内部への釣糸の侵入防止を図る糸落ち防止部材８１がスプール５９内に装着されている。 Further, a known reverse rotation prevention mechanism 75 using a one-way clutch 73 for preventing reverse rotation of the handle 43 during casting or fishing line winding operation is mounted on the outer periphery of the substantially intermediate portion of the rotary shaft 31. The switching lever 77 of the reverse rotation prevention mechanism 75 is mounted on the rear side of the reel body 35.
As with the conventional example shown in FIG. 7, the spinning reel 79 according to the present embodiment also includes a spool drop prevention member 81 for preventing the fishing line from entering the spool 59 and the rotor 37 in addition to the above-described configuration. 59 is mounted.

図１乃至図３に示すように糸落ち防止部材８１は、スプール軸５７に位置決め嵌合した軸受８３を介してスプール軸５７に回転可能且つスプール軸５７と共にリール本体３５の前後方向へ往復動可能に支持されたリング状の基部８５と、この基部８５から径方向外方且つ後方へ延出された４本の継ぎフレーム８７と、継ぎフレーム８７の他端側に連設された第１環状部８９と、この第１環状部８９の後端に於て、径方向外方に位置する第２環状部９１と、第２環状部９１の径方向外方へ突設され、ロータ３７の支持アーム４９の内周に設けた係合溝９３に係合する一対の係合突起９５とで構成されており、基部８５と第１環状部８９，第２環状部９１は中心軸を同じくしている。   As shown in FIGS. 1 to 3, the thread drop prevention member 81 can rotate to the spool shaft 57 through a bearing 83 positioned and fitted to the spool shaft 57 and can reciprocate in the front-rear direction of the reel body 35 together with the spool shaft 57. A ring-shaped base 85 supported by the base 85, four joint frames 87 extending radially outward and rearward from the base 85, and a first annular portion connected to the other end of the joint frame 87 89, a second annular portion 91 located radially outward at the rear end of the first annular portion 89, and a radially outwardly projecting second annular portion 91, and a support arm of the rotor 37 49, and a pair of engaging projections 95 that engage with an engaging groove 93 provided on the inner periphery of 49. The base 85, the first annular portion 89, and the second annular portion 91 have the same central axis. .

そして、図２に示すように糸落ち防止部材８１は、第１環状部８９がスプール５９のスカート部７１の内周面と径方向内方に所定の間隔を以って対向配置されると共に、第２環状部９１がスカート部７１の後端縁よりリール本体３５側に配置されて、第２環状部９１の外周がスカート部７１の外周と略面一に配置されている。
更に、図２及び図３に示すようにスカート部７１の内周面の径方向内方に対向する第１環状部８９の外周に、径方向外方へ突出する突片（突出部）９７が周方向に等間隔に複数突設され、更にまた、前記基部８５の外周に、径方向外方へ突出する突片（突出部）９９が周方向に等間隔に複数突設されている。 As shown in FIG. 2, the thread drop prevention member 81 includes a first annular portion 89 that is disposed to face the inner peripheral surface of the skirt portion 71 of the spool 59 with a predetermined interval radially inward. The second annular portion 91 is disposed on the reel body 35 side from the rear end edge of the skirt portion 71, and the outer periphery of the second annular portion 91 is disposed substantially flush with the outer periphery of the skirt portion 71.
Further, as shown in FIGS. 2 and 3, a projecting piece (projecting portion) 97 projecting radially outward is formed on the outer periphery of the first annular portion 89 facing the radially inner side of the inner peripheral surface of the skirt portion 71. A plurality of protrusions (protrusions) 99 projecting outward in the radial direction are provided on the outer periphery of the base portion 85 at equal intervals in the circumferential direction.

而して、糸落ち防止部材８１は、ＡＢＳ，ＰＰＳ等の合成樹脂やアルミ等の金属等で一体成形されており、図４に示すように前記突片９７は、例えば金型で糸落ち防止部材８１を鋳造する際に入れ子（ピン）１０１を立てて形成される。
この結果、図２乃至図４に示すように第１環状部８９の周壁と、スプール５９の軸方向に対して略直角な第２環状部９１の壁状部には、入れ子形成による肉抜きの孔１０３が各突片９７毎に形成されており、これらの孔１０３によって糸落ち防止部材８１の軽量化が図られ、また、切削に変えての金型成形による製造コストの低廉化が図られている。 Thus, the thread drop prevention member 81 is integrally formed of a synthetic resin such as ABS or PPS, or a metal such as aluminum, and as shown in FIG. When the member 81 is cast, the insert (pin) 101 is erected.
As a result, as shown in FIGS. 2 to 4, the peripheral wall of the first annular portion 89 and the wall-shaped portion of the second annular portion 91 that is substantially perpendicular to the axial direction of the spool 59 are thinned by forming a nest. A hole 103 is formed for each projecting piece 97, and the weight of the thread drop prevention member 81 is reduced by these holes 103, and the manufacturing cost is reduced by die molding instead of cutting. ing.

また、図２に示すように前記支持アーム４９の係合溝９３に係合する係合突起９５には、その基部側（第２環状部９１側）から支持アーム４９方向へ向かってスプール５９の前方へ傾斜する、即ち、係合突起９５の端部が頂部となる山形の傾斜面１０５が設けられており、斯かる構造によって係合突起９５に引っ掛かった釣糸を傾斜面１０５が積極的に基部側に案内して、ロータ３７内部への釣糸の侵入防止を図っている。   Further, as shown in FIG. 2, the engagement protrusion 95 that engages with the engagement groove 93 of the support arm 49 has a spool 59 that extends from the base side (second annular portion 91 side) toward the support arm 49. An angled inclined surface 105 is provided which is inclined forward, that is, the end of the engaging projection 95 is the top, and the inclined surface 105 positively catches the fishing line caught by the engaging projection 95 by such a structure. The fishing line is guided to the side to prevent the fishing line from entering the rotor 37.

本実施形態はこのように構成されているから、ハンドル４３の巻取り操作に伴い、糸落ち防止部材８１はロータ３７と共に回転し乍ら、前記支持アーム４９の係合溝９３に沿ってスプール５９と共に前後方向へ往復動するが、糸落ち防止部材８１の第２環状部９１の外周がスカート部７１の外周と略面一に配置されているため、スカート部７１の後端からスプール５９内への釣糸の糸落ちが第２環状部９１によって防止される。   Since the present embodiment is configured in this way, the spool 59 along the engagement groove 93 of the support arm 49 while the thread drop prevention member 81 rotates together with the rotor 37 as the handle 43 is wound. At the same time, the outer periphery of the second annular portion 91 of the yarn drop prevention member 81 is arranged substantially flush with the outer periphery of the skirt portion 71, so that the rear end of the skirt portion 71 enters the spool 59. The second annular portion 91 prevents the fishing line from dropping.

一方、ロータ３７内部への釣糸の糸落ちが係合突起９５によって防止されるが、既述したように係合突起９５には、係合突起９５に引っ掛かった釣糸を積極的に基部側に案内する傾斜面１０５が設けられているため、図８のストレート形状の係合突起２３に比し、積極的にロータ３７内部への釣糸の侵入防止が図られることとなる。
そして、図８の環状突起２７に比し、本実施形態の周方向に形成した複数の突片９７の方が釣糸が引っ掛かり易いため、仮にスカート部７１の後端からスプール５９の内方に釣糸が糸落ちしても、第１環状部８９の外周に突設した複数の突片９７に釣糸が引っ掛かってスプール５９内部への確実な侵入阻止が図られる。 On the other hand, the fishing line is prevented from dropping into the rotor 37 by the engaging protrusion 95, but as described above, the fishing line caught by the engaging protrusion 95 is actively guided to the base side. Since the inclined surface 105 is provided, the fishing line can be more actively prevented from entering the rotor 37 as compared with the straight engagement protrusion 23 of FIG.
8, the plurality of projecting pieces 97 formed in the circumferential direction of the present embodiment are more likely to catch the fishing line. Therefore, the fishing line is assumed to be inward of the spool 59 from the rear end of the skirt portion 71. Even if the line is dropped, the fishing line is caught on the plurality of projecting pieces 97 projecting from the outer periphery of the first annular portion 89, so that the intrusion into the spool 59 is surely prevented.

また、釣場の状況変化等により、仮に釣糸が更にスプール５９の内部に侵入しても、基部８５の外周に突設した複数の突片９９が、スプール軸５７回りへの釣糸の更なる侵入阻止を図ることとなる。
従って、本実施形態によれば、スプール５９内部やロータ３７内部への釣糸の侵入防止を確実に図ることが可能となり、最悪の釣糸の絡み付きを防止することができることとなった。 Further, even if the fishing line further enters the inside of the spool 59 due to a change in the situation of the fishing ground, the plurality of projecting pieces 99 projecting from the outer periphery of the base 85 further intrudes the fishing line around the spool shaft 57. It will try to prevent it.
Therefore, according to the present embodiment, it is possible to reliably prevent the fishing line from entering the spool 59 and the rotor 37, and to prevent the worst entanglement of the fishing line.

また、既述したように本実施形態は、糸落ち防止部材８１の金型成形時に、入れ子１０１形成による肉抜きの孔１０３が各突片９７毎に形成されているため、これらの孔１０３によって糸落ち防止部材８１の軽量化が図れると共に、切削に変えての金型成形により、製造コストの低廉化が図れる利点を有する。
図５は請求項１及び請求項２の第二実施形態に係るスピニングリールの要部拡大断面図を示し、本実施形態は、前記突片９７の先端側にリール本体３５の後方へ突出する係止爪１０７を設けて、突片９７による釣糸の侵入防止をより確実にしたものである。 In addition, as described above, in the present embodiment, when the thread drop prevention member 81 is molded with the die 103, the hollow holes 103 formed by the nest 101 are formed for each of the projecting pieces 97. The thread drop prevention member 81 can be reduced in weight, and has the advantage that the manufacturing cost can be reduced by die molding instead of cutting.
FIG. 5 is an enlarged cross-sectional view of the main part of the spinning reel according to the second embodiment of claims 1 and 2. In this embodiment, the projecting piece 97 projects to the rear side of the reel main body 35 at the front end side. A catch pawl 107 is provided to more reliably prevent the fishing line from entering by the projecting piece 97.

そして、図４で既述したように前記実施形態では、入れ子１０１による金型成形で突片９７を形成したが、図５に示すように上型１０９と下型１１１とによって糸落ち防止部材８１を金型成形するに当たり、前記突片９７と係止爪１０７，孔１０３が形成できるように上型１０９と下型１１１の当接面を加工処理することで、前記係止爪１０７を有する突片９７を備えた糸落ち防止部材８１を金型成形することも可能である。   As described above with reference to FIG. 4, in the above-described embodiment, the protruding piece 97 is formed by mold forming with the insert 101. However, as shown in FIG. 5, the thread drop prevention member 81 is formed by the upper mold 109 and the lower mold 111. When the die is molded, the abutment surfaces of the upper die 109 and the lower die 111 are processed so that the protruding pieces 97, the engaging claws 107, and the holes 103 can be formed. It is also possible to mold the thread drop prevention member 81 provided with the piece 97.

而して、本実施形態によれば、突片９７に係止爪１０７を設けたことで、突片９７による釣糸の侵入防止がより確実になると共に、肉抜きの孔１０３が各突片９７毎に形成されて糸落ち防止部材８１の軽量化が図れる利点を有する。
