特開２０００−２１３５６６号公報（特許文献２）では引き抜き加工によって、特開２００３−５６６０１号公報（特許文献３）ではブローチ加工によって、それぞれ外輪の外径面に***部を形成している。これらの加工方法は、作業工数および作業コストが非常に高いので、結果として製品コストの増大を招く。   In Japanese Patent Laid-Open No. 2000-213566 (Patent Document 2), a raised portion is formed on the outer diameter surface of the outer ring by drawing, and in Japanese Patent Laid-Open No. 2003-56601 (Patent Document 3), broached. These processing methods have very high work man-hours and work costs, resulting in an increase in product costs.

そこで、この発明の目的は、シェル外輪のハウジング内での滑りを有効に防止すると共に、製品コストを抑えた一方向クラッチを採用することによって、信頼性の高い釣用リール装置を提供することである。   Accordingly, an object of the present invention is to provide a highly reliable fishing reel device by effectively preventing slipping of the shell outer ring in the housing and adopting a one-way clutch with reduced product cost. is there.

この発明に係る釣用リール装置は、ハウジングと、ハウジングに回転自在に保持される回転軸と、回転軸の一方側に連結されて回転軸を回転させるハンドルと、回転軸の他方側に連結されて釣糸を巻回するスプールと、ハウジングおよび回転軸の間に配置され、回転軸の一方方向への回転のみを許容し、他方方向への回転を阻止する一方向クラッチとを備える。一方向クラッチに注目すると、外径寸法が相対的に大きい第１の部分と、外径寸法が第１の部分より小さい第２の部分とを含む外径面、軸方向に延びる複数のカム面が形成された軌道面を含む内径面、および軸方向端部に径方向内側に折り曲げられた端曲げ部を含み、ハウジングに嵌まり込むシェル外輪と、カム面の径方向内側の円周方向一方側と他方側とで径方向の隙間が異なる楔空間に配置される総ころ形式のころと、ころを楔空間の径方向隙間が減少する方向に付勢する弾性部材と、シェル外輪の内径面に嵌まり込んで端曲げ部に軸方向外側から保持される側板とを備える。   A fishing reel device according to the present invention is connected to a housing, a rotating shaft rotatably supported by the housing, a handle connected to one side of the rotating shaft to rotate the rotating shaft, and the other side of the rotating shaft. A spool for winding the fishing line, and a one-way clutch that is disposed between the housing and the rotating shaft and that allows only rotation of the rotating shaft in one direction and prevents rotation in the other direction. When attention is paid to the one-way clutch, an outer diameter surface including a first portion having a relatively large outer diameter size and a second portion having an outer diameter size smaller than the first portion, and a plurality of cam surfaces extending in the axial direction A shell outer ring that fits into the housing, and an inner circumferential surface that is radially inward of the cam surface. A roller of a full roller type that is disposed in a wedge space having a radial gap different between the side and the other side, an elastic member that urges the roller in a direction in which the radial gap of the wedge space decreases, and an inner diameter surface of the shell outer ring And a side plate that is held from the outside in the axial direction at the end bending portion.

上記構成の一方向クラッチは、シェル外輪がハウジングに圧入されると共に、その外径面が廻り止め部として機能する。これにより、シェル外輪の耐クリープ力を大幅に向上することができる。また、シェル外輪の軸方向端部に側板を設けたことにより、シェル外輪の内部に配置される構成部品の軸方向への抜けを有効に防止することができる。さらに、このシェル外輪は、プレス加工によって製造可能であるので、製造工数および製造コストを大幅に削減することができる。   In the one-way clutch configured as described above, the shell outer ring is press-fitted into the housing, and the outer diameter surface thereof functions as a detent portion. Thereby, the creep resistance of the shell outer ring can be greatly improved. Further, by providing the side plate at the axial end of the shell outer ring, it is possible to effectively prevent the components arranged inside the shell outer ring from coming off in the axial direction. Furthermore, since this shell outer ring can be manufactured by press working, manufacturing man-hours and manufacturing costs can be greatly reduced.

好ましくは、シェル外輪は、内径面の端曲げ部に隣接する位置に側板を受け入れる側板案内面を有する。そして、軌道面の板厚をｔ１、側板案内面の板厚をｔ２とすると、０．６≦ｔ２／ｔ１≦０．８を満たす。これにより、側板が軌道面の方向に移動してころの回転を阻害するのを有効に防止することができる。 Preferably, the shell outer ring has a side plate guide surface that receives the side plate at a position adjacent to the end bending portion of the inner diameter surface. When the plate thickness of the raceway surface is t 1 and the plate thickness of the side plate guide surface is t 2 , 0.6 ≦ t 2 / t 1 ≦ 0.8 is satisfied. Accordingly, it is possible to effectively prevent the side plate from moving in the direction of the raceway surface and inhibiting the rotation of the rollers.

さらに好ましくは、端曲げ部の板厚をｔ３とすると、０．６≦ｔ３／ｔ２≦０．８を満たす。これにより、側板案内面と端曲げ部との間に、端曲げ部の曲げの起点となる段差が形成される。 More preferably, when the plate thickness of the end bent portion is t 3 , 0.6 ≦ t 3 / t 2 ≦ 0.8 is satisfied. As a result, a step is formed between the side plate guide surface and the end bend as a starting point for bending the end bend.

この発明によれば、プレス加工によって廻り止め部を形成したので、一方向クラッチの製造コストを抑えることができる。そして、このような一方向クラッチを逆転防止機構として採用することにより、信頼性の高い釣用リール装置を得ることができる。   According to this invention, since the anti-rotation portion is formed by pressing, the manufacturing cost of the one-way clutch can be suppressed. By adopting such a one-way clutch as a reverse rotation prevention mechanism, a highly reliable fishing reel device can be obtained.

まず、図１を参照して、この発明の一実施形態に係る釣用リール装置１を説明する。なお、図１は釣用リール装置１の概略断面図である。   First, a fishing reel device 1 according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic sectional view of the fishing reel device 1.

釣用リール装置１は、釣糸を巻回するスプール２と、スプール２を両端から狭持する側方部材３，４と、スプール２を回転させるハンドル５と、ハウジングとしての側方部材４に収容され、ハンドル５の回転をスプール２に伝達する回転伝達機構とを主に備える。なお、釣用リール装置１の軽量化の観点から、例えば、側方部材３，４は樹脂材料等で形成されている。   The fishing reel device 1 is accommodated in a spool 2 for winding a fishing line, side members 3 and 4 for holding the spool 2 from both ends, a handle 5 for rotating the spool 2, and a side member 4 as a housing. And a rotation transmission mechanism that transmits the rotation of the handle 5 to the spool 2. From the viewpoint of reducing the weight of the fishing reel device 1, for example, the side members 3 and 4 are made of a resin material or the like.

回転伝達機構は、駆動軸６と、従動軸７と、駆動軸６に連結される駆動歯車８と、従動軸７に連結される従動歯車９と、側方部材４と駆動軸６との間に配置される逆転防止機構としての一方向クラッチ１１とを備える。   The rotation transmission mechanism includes a drive shaft 6, a driven shaft 7, a drive gear 8 connected to the drive shaft 6, a driven gear 9 connected to the driven shaft 7, and the side member 4 and the drive shaft 6. And a one-way clutch 11 as a reverse rotation preventing mechanism.

回転軸としての駆動軸６は、側方部材４に軸受（図示省略）によって回転自在に支持されている。また、駆動軸６の一方側はハンドル５と、他方側は駆動歯車８、従動歯車９、および従動軸７を介してスプール２とそれぞれ連結しており、ハンドル５と駆動軸６とは常に一体回転する。従動軸７は、側方部材４に軸受（図示省略）によって回転自在に支持されている。また、従動軸７の一方側端部はスプール２に連結されている。   The drive shaft 6 as a rotation shaft is rotatably supported on the side member 4 by a bearing (not shown). Further, one side of the drive shaft 6 is connected to the handle 5 and the other side is connected to the spool 2 via the drive gear 8, the driven gear 9, and the driven shaft 7, and the handle 5 and the drive shaft 6 are always integrated. Rotate. The driven shaft 7 is rotatably supported on the side member 4 by a bearing (not shown). One end of the driven shaft 7 is connected to the spool 2.

駆動歯車８は駆動軸６に嵌合して一体回転する。従動歯車９は従動軸７に嵌合して一体回転する。そして、駆動歯車８と従動歯車９とは噛合った状態となっている。したがって、駆動軸６と従動軸７とは常に逆回転する。同様に、スプール２とハンドル５とも逆回転する。   The drive gear 8 is fitted to the drive shaft 6 and rotates integrally. The driven gear 9 is fitted to the driven shaft 7 and rotates integrally. The drive gear 8 and the driven gear 9 are in mesh with each other. Therefore, the drive shaft 6 and the driven shaft 7 always rotate in the reverse direction. Similarly, the spool 2 and the handle 5 rotate in the reverse direction.

一方向クラッチ１１は、側方部材４に圧入されると共に内径面に駆動軸６を受け入れる。そして、駆動軸６の一方方向の回転（図１中の矢印イの方向。以下「正転」という）のみを許容し、他方方向への回転（図１中の矢印ロの方向。以下「逆転」という）を阻止する逆転防止機構として動作する。   The one-way clutch 11 is press-fitted into the side member 4 and receives the drive shaft 6 on the inner diameter surface. Then, only the rotation of the drive shaft 6 in one direction (the direction of arrow A in FIG. 1; hereinafter referred to as “forward rotation”) is allowed, and the rotation in the other direction (the direction of arrow B in FIG. 1; hereinafter “reverse rotation”). It works as a reverse-rotation prevention mechanism.

図２〜図７を参照して、図１に示す一方向クラッチ１１を説明する。なお、図２は一方向クラッチ１１を回転軸線と平行な平面で切断した断面図、図３は図２のＩＩＩ−ＩＩＩにおける断面図、図４および図５はＣ形ばね１９の形状を示す図、図６および図７は側板２０の形状を示す図である。   The one-way clutch 11 shown in FIG. 1 will be described with reference to FIGS. 2 is a cross-sectional view of the one-way clutch 11 taken along a plane parallel to the rotation axis, FIG. 3 is a cross-sectional view taken along line III-III in FIG. 2, and FIGS. 4 and 5 are views showing the shape of the C-shaped spring 19. 6 and 7 are diagrams showing the shape of the side plate 20.

まず、図２および図３を参照して、一方向クラッチ１１は、シェル外輪１２と、シェル外輪１２の内径面に沿って配置される複数のころ１８と、弾性部材としてのＣ形ばね１９と、シェル外輪１２の軸方向一方側端部に配置される側板２０とを備える。なお、この実施形態における一方向クラッチ１１は総ころ形式である。   2 and 3, the one-way clutch 11 includes a shell outer ring 12, a plurality of rollers 18 arranged along the inner diameter surface of the shell outer ring 12, and a C-shaped spring 19 as an elastic member. And a side plate 20 disposed at one end portion in the axial direction of the shell outer ring 12. In addition, the one-way clutch 11 in this embodiment is a full roller type.

シェル外輪１２は、外径寸法が相対的に大きい第１の部分１３ａおよび外径寸法が第１の部分１３ａより小さい第２の部分１３ｂを含む外径面と、ころ１８と接触する軌道面１４および側板２０を受け入れる側板案内面１５を含む内径面と、軌道面１４に隣接する軸方向一方側端部から径方向内側に突出する鍔部１６と、側板案内面１５に隣接する軸方向他方側端部に端曲げ部１７とを備える。   The shell outer ring 12 includes an outer diameter surface including a first portion 13 a having a relatively large outer diameter and a second portion 13 b having an outer diameter smaller than the first portion 13 a, and a raceway surface 14 in contact with the roller 18. And an inner diameter surface including the side plate guide surface 15 for receiving the side plate 20, a flange portion 16 projecting radially inward from one axial end adjacent to the raceway surface 14, and the other axial side adjacent to the side plate guide surface 15. An end bent portion 17 is provided at the end.

また、円周方向の一箇所にＣ形ばね１９の一方側端部を受け入れる係合部１２ａが形成されている。なお、この実施形態における係合部１２ａは、端曲げ部１７、側板案内面１５、および軌道面１４にかけてシェル外輪１２を厚み方向に貫通している例を示したが、係合部１２ａは少なくとも軌道面１４にのみ形成すればよい。具体的には、軌道面１４の所定位置に係合部１２ａとなる貫通孔を設けてもよいし、軌道面１４から側板案内面１５にかけて軸方向に拡がる貫通孔を設けてもよい。   Further, an engaging portion 12a that receives one end of the C-shaped spring 19 is formed at one place in the circumferential direction. In addition, although the engaging part 12a in this embodiment showed the example which has penetrated the shell outer ring | wheel 12 in the thickness direction over the end bending part 17, the side-plate guide surface 15, and the track surface 14, the engaging part 12a is at least What is necessary is just to form only in the track surface 14. Specifically, a through hole serving as the engaging portion 12a may be provided at a predetermined position of the raceway surface 14, or a through hole extending in the axial direction from the raceway surface 14 to the side plate guide surface 15 may be provided.

また、係合部１２ａは、シェル外輪１２の内径面に設けられた不貫通凹部であってもよい。この場合も、少なくとも軌道面１４にのみ形成すればよい。具体的には、不貫通凹部の凹み量を調整して、軌道面１４の所定位置に凹み量が（ｔ１−ｔ２）以下で軸方向に延びる溝を、または軌道面１４から側板案内面１５にかけて凹み量が（ｔ１−ｔ３）以下で軸方向に延びる溝を、さらには軌道面１４から端曲げ部１７にかけて凹み量がｔ１未満で軸方向に延びる溝を形成してもよい。なお、上記の各係合部は、いずれもプレス加工によって形成することができる。 Further, the engaging portion 12 a may be a non-penetrating recess provided on the inner diameter surface of the shell outer ring 12. Also in this case, it is sufficient to form at least on the raceway surface 14. Specifically, by adjusting the amount of depression of the non-penetrating recess, a groove extending in the axial direction when the amount of depression is (t 1 -t 2 ) or less at a predetermined position of the raceway surface 14 or the side plate guide surface from the raceway surface 14. A groove extending in the axial direction with a dent amount of (t 1 −t 3 ) or less from 15 to 15 and a groove extending in the axial direction with a dent amount less than t 1 from the raceway surface 14 to the end bending portion 17 may be formed. . Each of the engaging portions can be formed by pressing.

シェル外輪１２の外径面は、第１および第２の部分１３ａ，１３ｂを含む非円筒形状であって、側方部材４の内径面に嵌合したときに、シェル外輪１２が側方部材４の内部で滑るのを防止する廻り止め部として機能する。   The outer diameter surface of the shell outer ring 12 has a non-cylindrical shape including the first and second portions 13a and 13b. It functions as a detent that prevents sliding inside.

なお、シェル外輪１２の外径面は、非円筒形状であれば任意の形状を採用することができる。例えば、多角形状（六角形、八角形、十二角形等）や歯車形状等であってもよい。なお、この実施形態においては、後述する軌道面１４の形状に対応した形状となっており、シェル外輪１２の板厚は円周方向の全ての位置で略同一となっている。   In addition, as long as the outer-diameter surface of the shell outer ring | wheel 12 is non-cylindrical shape, arbitrary shapes are employable. For example, it may be a polygonal shape (hexagonal, octagonal, dodecagonal, etc.) or gear shape. In this embodiment, the shape corresponds to the shape of the raceway surface 14 to be described later, and the thickness of the shell outer ring 12 is substantially the same at all positions in the circumferential direction.

軌道面１４には、軸方向に延びるカム面１４ａが複数箇所に形成されている。このカム面１４ａの径方向内側には、円周方向一方側と他方側とで径方向の隙間が異なる楔空間が形成されている。この実施形態においては、反時計回り方向（図２中の矢印ハの方向）に向かって径方向の隙間が増加（「拡大方向」という）し、時計回り方向（図２中の矢印ニの方向）に向かって径方向の隙間が減少している（「狭小方向」という）。そして、各楔空間には、ころ１８が配置されている。   On the raceway surface 14, cam surfaces 14 a extending in the axial direction are formed at a plurality of locations. On the radially inner side of the cam surface 14a, a wedge space is formed with different radial gaps on one side and the other side in the circumferential direction. In this embodiment, the radial gap increases in the counterclockwise direction (the direction of the arrow C in FIG. 2) (referred to as the “enlargement direction”), and the clockwise direction (the direction of the arrow D in FIG. 2). ), The radial gap decreases (referred to as “narrow direction”). A roller 18 is disposed in each wedge space.

側板案内面１５は、軌道面１４に隣接する位置に設けられており、側板２０の外径面を受け入れる。ここで、軌道面１４および側板案内面１５の内径寸法を同一とすれば、側板２０が軌道面１４の方向に移動してころ１８の回転を阻害するおそれがある。そこで、軌道面１４と側板案内面１５との間に段差を設けて、側板２０が軌道面１４側に移動するのを防止している。   The side plate guide surface 15 is provided at a position adjacent to the raceway surface 14 and receives the outer diameter surface of the side plate 20. Here, if the inner diameter dimensions of the raceway surface 14 and the side plate guide surface 15 are the same, the side plate 20 may move in the direction of the raceway surface 14 and hinder the rotation of the rollers 18. Therefore, a step is provided between the raceway surface 14 and the side plate guide surface 15 to prevent the side plate 20 from moving to the raceway surface 14 side.

具体的には、軌道面１４の位置におけるシェル外輪１２の板厚をｔ１、側板案内面１５の位置におけるシェル外輪１２の板厚をｔ２とすると、０．６≦ｔ２／ｔ１≦０．８の範囲内でｔ２を減じることによって、軌道面１４と側板案内面１５との間に段差を形成している（図１０参照）。 Specifically, assuming that the thickness of the shell outer ring 12 at the position of the raceway surface 14 is t 1 and the thickness of the shell outer ring 12 at the position of the side plate guide surface 15 is t 2 , 0.6 ≦ t 2 / t 1 ≦ By reducing t 2 within the range of 0.8, a step is formed between the raceway surface 14 and the side plate guide surface 15 (see FIG. 10).

鍔部１６は、軌道面１４に隣接するシェル外輪１２の軸方向一方側端部に位置する円環形状の部分である。この鍔部１６は、シェル外輪１２の内部に収容される構成部品（例えば、「ころ１８」、「Ｃ形ばね１９」等を指す）の軸方向への抜けを防止する。   The flange portion 16 is an annular portion located at one end portion in the axial direction of the shell outer ring 12 adjacent to the raceway surface 14. The flange portion 16 prevents a component (for example, “roller 18”, “C-shaped spring 19”, etc.) accommodated in the shell outer ring 12 from coming off in the axial direction.

端曲げ部１７は、側板案内面１５に隣接するシェル外輪１２の軸方向他方側端部に位置する部分である。この端曲げ部１７は、側板２０の外径面の角部を軸方向外側から保持して、側板２０の軸方向外側への抜けを防止する。なお、端曲げ部１７の位置におけるシェル外輪１２の板厚をｔ３とすると、０．６≦ｔ３／ｔ２≦０．８を満たすように、ｔ３を決定する（図１０を参照）。これにより、側板案内面１５と端曲げ部１７の境界部分に段差が形成される。この段差は、端曲げ部１７の曲げの起点となる。 The end bending portion 17 is a portion located at the other end portion in the axial direction of the shell outer ring 12 adjacent to the side plate guide surface 15. The end bent portion 17 holds the corner portion of the outer diameter surface of the side plate 20 from the outside in the axial direction, and prevents the side plate 20 from slipping out in the axial direction. Note that t 3 is determined so as to satisfy 0.6 ≦ t 3 / t 2 ≦ 0.8, where t 3 is the thickness of the shell outer ring 12 at the end bending portion 17 (see FIG. 10). . As a result, a step is formed at the boundary portion between the side plate guide surface 15 and the end bent portion 17. This step becomes a starting point of bending of the end bending portion 17.

図４および図５を参照して、Ｃ形ばね１９は、円弧形状のＣ形部１９ａと、Ｃ形部１９ａの一方側および他方側端部にＣ形部１９ａと交差（この実施形態では「直交」）する方向に延びる係合突起１９ｂ，１９ｃとを有する。   4 and 5, a C-shaped spring 19 has an arc-shaped C-shaped portion 19a, and intersects with the C-shaped portion 19a at one end and the other end of the C-shaped portion 19a (in this embodiment, “ Engaging projections 19b and 19c extending in the direction of "perpendicular").

このＣ形ばね１９は、一方向クラッチ１１に挿通する駆動軸６とシェル外輪１２との間に形成される環状空間に弾性縮径された状態で配置される。そして、一方側端部の係合突起１９ｂは係合部１２ａに係合し、他方側端部の係合突起１９ｃは隣接するころ１８の間の空間（ＰＣＤより外側の空間）に配置される。   The C-shaped spring 19 is arranged in an elastically reduced state in an annular space formed between the drive shaft 6 inserted through the one-way clutch 11 and the shell outer ring 12. The engagement protrusion 19b at the one end is engaged with the engagement part 12a, and the engagement protrusion 19c at the other end is disposed in the space between the adjacent rollers 18 (the space outside the PCD). .

図６および図７を参照して、側板２０は円環形状の部材である。この側板２０は、シェル外輪１２の側板案内面１５に嵌まり込んで、シェル外輪１２の内部に収容される構成部品（例えば、「ころ１８」、「Ｃ形ばね１９」等を指す）の軸方向への抜けを防止する。   6 and 7, the side plate 20 is a ring-shaped member. The side plate 20 is fitted into the side plate guide surface 15 of the shell outer ring 12 and is a shaft of a component (for example, “roller 18”, “C-shaped spring 19”, etc.) accommodated in the shell outer ring 12. Prevent slipping in the direction.

上記構成の一方向クラッチ１１は、例えば、内径面に駆動軸６を受け入れると共に、側方部材４に圧入される。また、側方部材４の内径面はシェル外輪１２の外径面に対応する形状となっている。   The one-way clutch 11 having the above configuration receives, for example, the drive shaft 6 on the inner surface and is press-fitted into the side member 4. Further, the inner diameter surface of the side member 4 has a shape corresponding to the outer diameter surface of the shell outer ring 12.

より具体的には、ハンドル５を正転させたときに駆動軸６が反時計方向（図３中の矢印ハの方向）に回転するように、一方向クラッチ１１を駆動軸６に嵌合させる。駆動軸６が反時計方向（図３中の矢印ハの方向）に回転するとき、ころ１８は楔空間の拡大方向に移動し、空転する。すなわち、駆動軸６の正転を許容する。このとき、従動軸７に連結されたスプール２は歯車８，９によって駆動軸６とは反対周りに回転し、釣糸を収容する。   More specifically, the one-way clutch 11 is fitted to the drive shaft 6 so that the drive shaft 6 rotates counterclockwise (the direction of arrow C in FIG. 3) when the handle 5 is rotated forward. . When the drive shaft 6 rotates counterclockwise (in the direction of arrow C in FIG. 3), the roller 18 moves in the expanding direction of the wedge space and idles. That is, normal rotation of the drive shaft 6 is allowed. At this time, the spool 2 connected to the driven shaft 7 is rotated around the opposite side of the drive shaft 6 by the gears 8 and 9 and accommodates the fishing line.

一方、スプール２を正転（釣糸が繰り出される方向）させようとすると、駆動軸６が逆転しようとする。駆動軸６が時計方向（図３中の矢印ニの方向）に回転するとき、ころ１８は楔空間の狭小方向に移動し、シェル外輪１２と駆動軸６との間に噛み合って、駆動軸６の逆転を阻止する。つまり、獲物の引き等によって釣糸が繰り出されるのを防止することができる。   On the other hand, when the spool 2 is rotated in the forward direction (the direction in which the fishing line is fed out), the drive shaft 6 tries to reversely rotate. When the drive shaft 6 rotates in the clockwise direction (the direction of arrow D in FIG. 3), the roller 18 moves in the narrowing direction of the wedge space and engages between the shell outer ring 12 and the drive shaft 6 to drive the drive shaft 6. To prevent reversal. That is, it is possible to prevent the fishing line from being unwound by pulling the prey.

ここで、シェル外輪１２と側方部材４とは、嵌め合いによって固定されていると共に、非円筒形状の外径面１３が廻り止め部として機能する。これにより、駆動軸６がロックしたときの伝達トルクが大きくても、シェル外輪１２が側方部材４の内部で滑るのを確実に防止することができる。この発明は、側方部材４が樹脂等の比較的剛性の低い材料で形成されている場合に、特に有利な効果を奏する。   Here, the shell outer ring 12 and the side member 4 are fixed by fitting, and the non-cylindrical outer diameter surface 13 functions as a detent portion. Thereby, even if the transmission torque when the drive shaft 6 is locked is large, it is possible to reliably prevent the shell outer ring 12 from sliding inside the side member 4. The present invention has a particularly advantageous effect when the side member 4 is formed of a material having relatively low rigidity such as resin.

また、Ｃ形ばね１９は、一方側端部が係合部１２ａに係合した状態で拡径しようとして（元の状態に復帰しようとして）、ころ１８を狭小方向（図３中の矢印ニの方向）に付勢する。これにより、ころ１８の遊度が小さくなるので、駆動軸６の逆転を敏速に停止させることが可能となる。なお、弾性部材は、図４および図５に示すＣ形ばね１９に限らず、ころ１８を狭小方向に付勢可能なあらゆる形態を採用することができる。   Further, the C-shaped spring 19 attempts to expand the diameter in a state where the one end portion is engaged with the engaging portion 12a (an attempt to return to the original state), and the roller 18 is narrowed in the narrow direction (indicated by the arrow D in FIG. Direction). Thereby, since the play of the roller 18 becomes small, it becomes possible to stop the reverse rotation of the drive shaft 6 promptly. The elastic member is not limited to the C-shaped spring 19 shown in FIGS. 4 and 5, and any form that can bias the roller 18 in the narrow direction can be adopted.

また、シェル外輪１２の軸方向一方側端部に鍔部１６を、軸方向他方側端部に側板２０をそれぞれ設けたことにより、ころ１８やＣ形ばね１９等の軸方向への抜けを防止することができる。さらに、側板案内面１５の一方側に段差を設け、他方側に端曲げ部１７を設けたことによって、シェル外輪１２と側板２０を強固に一体化することができる。   In addition, the flange 16 is provided at one end of the shell outer ring 12 in the axial direction and the side plate 20 is provided at the other end in the axial direction, thereby preventing the rollers 18 and the C-shaped spring 19 from coming off in the axial direction. can do. Furthermore, the shell outer ring 12 and the side plate 20 can be firmly integrated by providing a step on one side of the side plate guide surface 15 and providing the end bent portion 17 on the other side.

次に、図８〜図１５を参照して、一方向クラッチ１１の製造方法を説明する。なお、図８は一方向クラッチ１１の製造方法の主な工程を示すフロー図、図９〜図１５は各工程におけるシェル外輪１２の形状を示す図である。   Next, a method for manufacturing the one-way clutch 11 will be described with reference to FIGS. 8 is a flowchart showing the main steps of the manufacturing method of the one-way clutch 11, and FIGS. 9 to 15 are views showing the shape of the shell outer ring 12 in each step.

まず、図８および図９を参照して、第１の工程では、打ち抜き加工によって鋼板から円盤２１を得る（Ｓ１１）。   First, referring to FIG. 8 and FIG. 9, in the first step, a disk 21 is obtained from a steel plate by punching (S11).

次に、図８、図１０、および図１１を参照して、第２の工程では、絞り加工によって円盤２１をカップ状部材２２に成形すると共に、外径面１３および軌道面１４を所定の形状に成形する（Ｓ１２）。具体的には、内径面の形状がシェル外輪１２の外径面１３に対応するダイス（図示省略）に円盤２１を載置し、外径面の形状がシェル外輪１２の軌道面１４の形状に対応するポンチ（図示省略）によって絞り加工を行う。   Next, referring to FIG. 8, FIG. 10, and FIG. 11, in the second step, the disk 21 is formed into a cup-shaped member 22 by drawing, and the outer diameter surface 13 and the raceway surface 14 have a predetermined shape. (S12). Specifically, the disk 21 is placed on a die (not shown) whose inner diameter surface corresponds to the outer diameter surface 13 of the shell outer ring 12, and the outer diameter surface becomes the shape of the raceway surface 14 of the shell outer ring 12. Drawing is performed by a corresponding punch (not shown).

なお、１度の絞り加工によってカップ状部材２２を得てもよいし、複数回の絞り加工を経てカップ状部材２２を形成してもよい。また、この工程において、カップ状部材２２の開放側端部の内径面の板厚を減じて、側板案内面１５および端曲げ部１７を形成する。   Note that the cup-shaped member 22 may be obtained by a single drawing process, or the cup-shaped member 22 may be formed through a plurality of drawing processes. Further, in this step, the side plate guide surface 15 and the end bent portion 17 are formed by reducing the plate thickness of the inner diameter surface of the open side end portion of the cup-shaped member 22.

次に、図８および図１２を参照して、第３の工程では、打ち抜き加工によって鍔部１６を残して、カップ状部材２２の底壁２２ａを除去する（Ｓ１３）。   Next, referring to FIG. 8 and FIG. 12, in the third step, the bottom wall 22a of the cup-shaped member 22 is removed while leaving the flange 16 by punching (S13).

次に、図８、図１３、および図１４を参照して、第４の工程では、カップ状部材２２の円周上の一箇所に軸方向に延びる係合部１２ａを形成する（Ｓ１４）。この実施形態においては、カップ状部材２２の開放側端部に設けられている。   Next, referring to FIG. 8, FIG. 13, and FIG. 14, in the fourth step, an engaging portion 12a extending in the axial direction is formed at one place on the circumference of the cup-shaped member 22 (S14). In this embodiment, the cup-shaped member 22 is provided at the open end.

次に、図８および図１５を参照して、第５の工程では、端曲げ部１７に端曲げ加工を施して、カップ状部材２２の開放側端部に所定の曲率を与える（Ｓ１５）。端曲げ部１７の先端の直径が小さすぎると、後述する第７の工程（Ｓ１７）で側板２０を組み込むことができない。一方、端曲げ部１７の先端の直径が大きすぎると、側板２０を安定して保持することができない。   Next, referring to FIGS. 8 and 15, in the fifth step, the end bending portion 17 is subjected to end bending to give a predetermined curvature to the open side end portion of the cup-shaped member 22 (S15). If the diameter of the end of the end bending portion 17 is too small, the side plate 20 cannot be incorporated in the seventh step (S17) described later. On the other hand, if the diameter of the tip of the end bending portion 17 is too large, the side plate 20 cannot be stably held.

次に、図８を参照して、第６の工程では、シェル外輪１２に必要な機械的性質を得るために、カップ状部材２２に熱処理を施す（Ｓ１６）。熱処理としては、例えば、浸炭窒化処理や浸炭焼入れ処理を施す。これにより、表面は硬く、内部は軟らかく靭性の高い性質が得られる。さらに、上記の熱処理によって生じた残留応力や内部ひずみを低減し、靭性の向上や寸法を安定化させるために、上記の熱処理の後に焼戻を行う。   Next, referring to FIG. 8, in the sixth step, heat treatment is performed on the cup-shaped member 22 in order to obtain the mechanical properties necessary for the shell outer ring 12 (S16). As the heat treatment, for example, carbonitriding or carburizing and quenching is performed. Thereby, the surface is hard, the inside is soft, and the property with high toughness is obtained. Further, tempering is performed after the heat treatment in order to reduce residual stress and internal strain generated by the heat treatment and to improve toughness and stabilize dimensions.

次に、図８および図２を参照して、第７の工程では、一方向クラッチ１１の組立を行う（Ｓ１７）。具体的には、図２に示すようにシェル外輪１２の内部に複数のころ１８およびＣ形ばね１９を組み込む。さらに、端曲げ部１７を弾性変形させながら側板２０をかち込む。   Next, referring to FIG. 8 and FIG. 2, in the seventh step, the one-way clutch 11 is assembled (S17). Specifically, as shown in FIG. 2, a plurality of rollers 18 and a C-shaped spring 19 are incorporated in the shell outer ring 12. Further, the side plate 20 is pushed in while the end bent portion 17 is elastically deformed.

上記の各工程を経て、図２および図３に示したような一方向クラッチ１１を得ることができる。このように、プレス加工によってシェル外輪１２の外径面１３に廻り止め部を形成すれば、従来の引き抜き加工やブローチ加工等によって外輪に廻り止め加工を施す場合と比較して、作業工数および作業コストを削減することができる。その結果、低廉な一方向クラッチ１１を得ることができる。   Through the above steps, the one-way clutch 11 as shown in FIGS. 2 and 3 can be obtained. In this way, if the rotation stop portion is formed on the outer diameter surface 13 of the shell outer ring 12 by press working, the work man-hours and work are reduced as compared with the case where the outer ring is subjected to rotation prevention processing by conventional drawing or broaching. Cost can be reduced. As a result, an inexpensive one-way clutch 11 can be obtained.

なお、図８に示した製造工程は、一方向クラッチ１１の製造方法の一部であって、さらに工程を追加してもよいし、各工程をさらに細分化してもよい。また、一部の工程については順序を相互に入れ替えることもできる。   Note that the manufacturing process shown in FIG. 8 is a part of the manufacturing method of the one-way clutch 11, and further processes may be added, or each process may be further subdivided. In addition, the order of some processes can be interchanged.

また、上記構成の釣用リール装置１は、操作性の観点から、歯車８，９を用いてハンドル５とスプール２とが逆回転するようにしたが、従動軸７および従動歯車９を省略して、駆動軸６の一方側にハンドル５を、他方側にスプール２をそれぞれ連結し、両者を同一方向に回転させる構成としても、この発明の効果を得ることができる。   In the fishing reel device 1 having the above-described configuration, the handle 5 and the spool 2 are rotated in reverse using the gears 8 and 9 from the viewpoint of operability, but the driven shaft 7 and the driven gear 9 are omitted. Thus, the effect of the present invention can be obtained even when the handle 5 is connected to one side of the drive shaft 6 and the spool 2 is connected to the other side and both are rotated in the same direction.

さらに、この発明の一実施形態に係る釣用リール装置１として、ベイトリールの例を示したが、この発明は他の構成の釣用リール装置にも適用することができる。例えば、スピニングリールにも適用することができる。   Furthermore, although the example of the bait reel was shown as the fishing reel apparatus 1 which concerns on one Embodiment of this invention, this invention is applicable also to the fishing reel apparatus of another structure. For example, it can be applied to a spinning reel.
