Description

Fishing reel drag mechanism

  The present invention relates to a drag device, and more particularly to a drag mechanism for a fishing reel capable of adjusting a drag force by braking rotation of a spool for spooling of a fishing reel in a line-feeding direction.

  The fishing reel is provided with a drag mechanism for braking the rotation of the spool in the line-feeding direction in order to adjust the drag force. The conventional drag mechanism includes an operation member for adjusting the drag force, a screw member into which the operation member is screwed, and a friction mechanism in which the friction force is changed by turning the operation member. For example, in a double-bearing reel or a single-bearing reel that winds a fishing line with a rotating spool, an operation member is screwed onto a drive shaft or a spool shaft as a screw member. Further, in a spinning reel in which a fishing line is wound around a stationary spool by a rotor, an operation member is screwed onto a spool shaft serving as a screw member (see, for example, Patent Document 1).

  In such a conventional drag mechanism, when the operating member is rotated, the screwed portion of the operating member moves in the axial direction of the screw member, and this movement changes the frictional force of the friction mechanism, thereby adjusting the drag force. it can.

JP 2009-148173 A

  In the conventional drag mechanism, when the operating member is rotated, the rotating operation of the operating member may be heavy. In particular, when a large drag force is set when it is necessary to constantly adjust the drag force as in jigging, such a phenomenon is likely to occur.

  An object of the present invention is to enable an operation member to be operated with a light operation force in a drag mechanism of a fishing reel even when the drag force increases.

  The fishing reel drag mechanism is a mechanism that brakes the rotation in the line-feeding direction of the spool for spooling the fishing reel. The fishing reel drag mechanism includes a first member having a male thread portion, a second member, a friction mechanism, and a fluororesin-containing electroless nickel plating film. The second member has an internal thread portion that is screwed into the external thread portion. The friction mechanism is a mechanism that changes the frictional force by relatively rotating the first member and the second member, and can brake the rotation of the spool in the yarn unwinding direction. The fluororesin-containing electroless nickel plating film is formed on at least one of the male screw portion and the female screw portion.

  In this drag mechanism, the frictional force of the friction mechanism is changed by adjusting one of the first member and the second member relative to the other member as an operation member, and the drag force can be adjusted. A fluororesin-containing electroless nickel plating film is formed on at least one of the male screw portion of the first member and the female screw portion of the second member. For this reason, the film thickness of the fluororesin-containing electroless nickel plating film becomes uniform, the sliding resistance between the male screw part and the female screw part that rotate relative to each other is reduced, and the relative rotation between the male screw part and the female screw part is smooth. become. Thereby, even if the drag force increases, the operation member can be operated with a light operation force. In addition, the squeak noise during operation of the operation member is reduced, and the operation feeling is improved.

  In the fishing reel drag mechanism, the fluororesin is polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), perfluoroalkoxy fluororesin (PFA) Selected from the group consisting of fluorinated ethylene / hexafluoropropylene copolymer (FEP), ethylene / tetrafluoroethylene copolymer (ETFE), and ethylene / chlorotrifluoroethylene copolymer (ECTFE) Good. In this case, a fluororesin having a particularly high slidability can be selected.

  In the fishing reel drag mechanism, the fishing reel may be a double-bearing reel or a single-bearing reel in which the spool is rotated by the rotation of the handle. The first member is a drive shaft that rotates as the handle rotates. The second member is an operation member that is screwed onto the drive shaft. The friction mechanism has at least one friction plate disposed on the drive shaft and pressed by the operation member. In this case, in the double-bearing reel or the single-bearing reel having the drag mechanism in which the friction plate is disposed around the drive shaft, the operation member can be operated with a light operation force even when the drag force increases.

  The fishing reel drag mechanism may further include a reverse rotation prevention mechanism that prohibits rotation of the drive shaft in the line-feeding direction. In this case, since the drive shaft does not rotate in the yarn unwinding direction, a star drag type drag mechanism can be configured by providing the friction plate so as to be integrally rotatable with at least the drive shaft.

  In the drag mechanism of the fishing reel, the fishing reel may be a spinning reel that winds freely around the spool shaft. The first member is a spool shaft on which the spool is rotatably mounted. The second member is an operation member that is screwed onto the spool shaft. The friction mechanism includes at least one friction plate disposed on the spool shaft and pressed by the operation member. In this case, in the spinning reel in which the friction plate is arranged around the spool shaft, the operation member can be operated with a light operation force even when the drag force is increased.

  In the fishing reel drag mechanism, the fluororesin-containing electroless nickel plating film may be formed on the male thread portion. In this case, since the fluororesin-containing electroless nickel plating film is formed on the male thread portion of the first member, the contact position between the fluororesin-containing electroless nickel plating film and the female screw portion is determined according to the drag force adjustment position. Change. For this reason, the life of the fluororesin-containing electroless nickel plating film can be extended.

  In the fishing reel drag mechanism, the fluororesin-containing electroless nickel plating film may be a composite plating film in which fluororesin fine particles are dispersed and co-deposited. In this case, the fluororesin-containing electroless nickel plating film can be formed while suppressing an increase in cost.

  In the fishing reel drag mechanism, the fluororesin-containing electroless nickel plating film is a composite plating film in which a fluororesin is combined with a porous film of nickel-phosphorus (Ni-P) deposited in particles by heat treatment. Good. In this case, the formation cost of the composite plating film increases, but the hardness of the composite plating film increases.

  According to the present invention, the sliding resistance between the male screw portion and the female screw portion that rotate relative to each other is reduced, and the relative rotation between the male screw portion and the female screw portion becomes smooth. Thereby, even if the drag force increases, the operation member can be operated with a light operation force.

  The drive shaft 30 is, for example, a metal shaft member made of stainless alloy. As shown in FIGS. 4 and 5, the drive shaft 30 includes a shaft support portion 30 a, a first locking portion 30 b, a flange portion 30 c, a second locking portion 30 d, and a third engagement from the proximal end side toward the distal end side.

The collar part 30c has a larger diameter than the first locking part 30b. The second locking portion 30d has a smaller diameter than the flange portion 30c, and includes two sets of chamfered portions that are parallel to each other. The 3rd latching | locking part 30e is smaller diameter than the 2nd latching | locking part 30d, and is comprised by one set of chamfering parts parallel to each other. The first male screw portion 30f is formed on the outer peripheral surface excluding the third locking portion 30e on the tip side of the third locking portion 30e. The second male screw portion 30g is formed at the distal end portion of the drive shaft 30 with a smaller diameter than the first male screw portion 30f. The 4th latching | locking part 30h is formed in the outer peripheral surface of the drive shaft 30 in which the 2nd external thread part 30g was formed. The handle 2 is non-rotatably attached to the fourth locking portion 30h, and the handle 2 is fixed to the drive shaft 30 by a nut 43 screwed into the second male screw portion 30g.

On the surface of the first male screw portion 30f, as shown schematically in FIG. 6, the fluorine resin-containing electroless nickel plating skin layer 90 is formed. In FIG. 6, the screw shape is omitted. Fluororesin-containing electroless nickel plating epithelial membrane 90 is a composite coating which is substantially formed uniformly dispersed eutectoid in the nickel plating solution fine particles of fluororesin. Fluororesin used in the fluororesin-containing electroless nickel plating epithelial membrane 90, polytetrafluoroethylene (PTFE), poly polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), perfluoroalkoxy fluorine From the group consisting of resin (PFA), fluorinated ethylene / hexafluoropropylene copolymer (FEP), ethylene / tetrafluoroethylene copolymer (ETFE), and ethylene / chlorotrifluoroethylene copolymer (ECTFE) Selected. Preferably, the fluororesin is polytetrafluoroethylene (PTFE). In FIG. 6, the fluororesin is schematically illustrated by dots. The film thickness of the fluororesin-containing electroless nickel plating transdermal film 90 is for example in the range of 2μm to 20 [mu] m, preferably in the range from 5μm to 15 [mu] m. The eutectoid amount of the fluororesin is, for example, 1.5 to 10 weight percent of the entire plating solution.

  The drive shaft 30 is rotatably mounted on the reel body 1 and is rotated (reversely rotated) in the yarn feeding direction by the roller-type first one-way clutch 86 and the claw-type second one-way clutch 87 that constitute the reverse rotation prevention mechanism 66. Is prohibited. The drive shaft 30 is rotatably supported by the second side cover 7 and the frame 5 by the bearing 28 and the first one-way clutch 86.

  The first one-way clutch 86 is disposed at an intermediate portion of the drive shaft 30 and is attached to a gap between the second side cover 7 of the reel body 1 and the drive shaft 30. The first one-way clutch 86 includes an outer ring 86a that is non-rotatably mounted on the second side cover 7, an inner ring 86b that is rotatably mounted on the drive shaft 30, and a roller disposed between the outer ring 86a and the inner ring 86b. 86c.

  The second one-way clutch 87 includes a ratchet wheel 61 and a ratchet pawl 67 (see FIG. 5) that is swingably attached to the outer surface of the second side plate 9 of the reel body 1. The ratchet wheel 61 is non-rotatably attached to the second locking portion 30d between the drive gear 31 and the gear member 49. The ratchet wheel 61 is disposed in contact with the flange portion 30c, and movement to the proximal end side is restricted by the flange portion 30c. On the outer peripheral portion of the ratchet wheel 61, ratchet teeth 61a formed so as to protrude in a substantially parallelogram shape are arranged at intervals in the circumferential direction. When the ratchet pawl 67 swingably mounted on the reel body 1 is engaged with the ratchet teeth 61a, the rotation of the drive shaft 30 in the yarn unwinding direction is prohibited. The second one-way clutch 87 functions as a friction plate for the drag mechanism 23.

  The drive gear 31 is rotatably mounted on the drive shaft 30 and is connected to the drive shaft 30 via the drag mechanism 23. The drag mechanism 23 brakes the rotation of the spool 12 in the yarn unwinding direction by braking the rotation of the drive gear 31 in the yarn unwinding direction.

  As shown in FIG. 3, the pinion gear 32 is a cylindrical member that extends inward from the outside of the second side plate 9 and through which the spool shaft 20 passes. The pinion gear 32 is attached to the spool shaft 20 so as to be movable in the axial direction. An engagement groove 32a that engages with an engagement pin 20b that penetrates the spool shaft 20 in the radial direction is formed at the left end of the pinion gear 32 in FIG. The clutch mechanism 21 is configured by the engagement groove 32 a and the engagement pin 20 b attached to the spool shaft 20. Further, a constricted portion 32 b is formed at the intermediate portion of the pinion gear 32, and a gear portion 32 c that meshes with the drive gear 31 is formed at the right end portion. The clutch yoke 22a of the clutch control mechanism 22 is engaged with the constricted portion 32b.

  The gear member 49 is non-rotatably attached to a first locking portion 30b formed at the base end portion of the drive shaft 30, and abuts against the flange portion 30c from the base end portion side. A gear member 48 attached to the traverse cam shaft 46 is engaged with a gear member 49 attached to the drive shaft 30. With such a configuration, the traverse cam shaft 46 of the level wind mechanism 18 rotates in conjunction with the rotation of the drive shaft 30 in the yarn winding direction.

The drag mechanism 23 is a mechanism that brakes the rotation of the spool 12 in the yarn unwinding direction by interlockingly rotating the drive shaft 30 and the drive gear 31 up to a set drag force. The drag force is adjusted by the tightening degree of the star drag 3. The drag mechanism 23, as shown in FIGS. 4 and 5, the star drag 3, and the drive shaft 30, and a friction mechanism 4, hydrofluoric Motoju described above is formed in the drive shaft 30 Abura含 whether the electroless nickel plating film 90 ( 6). The drag mechanism 23 includes a sound generation mechanism 65 and the reverse rotation prevention mechanism 66 described above.

  As shown in FIG. 3, the star drag 3 includes a main body part 3b having a plurality of operation parts 3a arranged radially, and a nut member 3c arranged in the main body part 3b so as to be integrally rotatable and axially movable. Have. The nut member 3c has a female screw portion 3d that is screwed into the first male screw portion 30f. The star drag 3 is an operation member for adjusting a predetermined drag force by pressing the friction mechanism 4 mounted on the drive shaft 30 on the proximal side. Four disc springs 88 are mounted between the star drag 3 and the first one-way clutch 86. The disc spring 88 is provided to gently transmit the tightening force of the star drag 3 to the drag plate 62 described later. The disc spring 88 is disposed between the nut member 3 c of the star drag 3 and the inner ring 86 b of the first one-way clutch 86.

  The star drag 3 is adjusted in the axial direction by adjusting the tightening degree so that the inner ring 86b of the first one-way clutch 86 with the drive shaft 30 mounted on the second side cover 7 passes through the disc spring 88 (see FIG. 3). Can be moved to. That is, the pressing force of the disc spring 88 is adjusted by the rotation of the star drag 3. Thereby, the drag force can be finely adjusted by the star drag 3.

  The friction mechanism 4 includes a drag plate 62 (an example of a friction plate) that engages with the drive shaft 30 so as to be integrally rotatable, and a ratchet wheel 61 (an example of a friction plate). The drag plate 62 is a disc member that comes into contact with the drive gear 31 (an example of a second friction plate) from the handle 2 side via the first drag washer 63a. The drag plate 62 is attached to the third locking portion 30e so as to be integrally rotatable with the drive shaft 30. The drag plate 62 sandwiches the drive gear 31 with the ratchet wheel 61. The drag plate 62 is non-rotatably connected to and abuts on the inner ring 86 b of the first one-way clutch 86. As a result, the inner ring 86 b of the first one-way clutch 86 cannot rotate with respect to the drive shaft 30 and transmits the pressing force of the star drag 3 to the drag plate 62. At the center of the drag plate 62, an engagement hole 62a that engages with the inner ring 86b so as to be integrally rotatable and engages with the third locking portion 30e of the drive shaft 30 so as to be integrally rotatable is formed. The drive gear 31 contacts the ratchet wheel 61 via the second drag washer 63b.

  The second drag washer 63 b is a ring-shaped friction disk disposed between the ratchet wheel 61 and the drive gear 31. A ring member 64 is disposed on the inner peripheral side of the second drag washer 63b. The ring member 64 is rotatable with respect to the drive shaft 30. The ring member 64 has a locking pin 64a on the drive gear 31 side. The locking pin 64a engages with one of a pair of locking holes 31a and 31b formed through the side surface of the drive gear 31. As a result, the ring member 64 rotates in conjunction with the drive gear 31. The ring member 64 is thinner than the second drag washer 63b. For this reason, even if the drag plate 62 is pressed by the star drag 3 and the drive gear 31 is sandwiched between the drag plate 62 and the ratchet wheel 61, the pressing force does not act on the ring member 64 and the ring gear 64 is rotatable.

  The sound generation mechanism 65 includes a striking pin 70 that is mounted on the gear member 49 so as to be movable back and forth in the drive axis direction, and a large number of sound outputs formed on the side surface of the ring member 64 opposite to the handle side at intervals in the circumferential direction. A recess 71 and a coil spring 72 that urges the striking pin 70 toward the ring member 64 are provided. The striking pin 70 has a head that engages with the sound generating recess 71 at the tip. The striking pin 70 and the coil spring 72 are accommodated in a cylindrical portion 49 a formed to project from the side surface of the gear member 49 on the handle side. The cylindrical portion 49a has a size that can be inserted into a through hole 61b formed in the vicinity of the center hole of the ratchet wheel 61, and is exposed to the ring member 64 side. A large number of sound emitting recesses 71 are formed on the side surface of the ring member 64 that can face the striking pin 70 at intervals in the circumferential direction. In the sound generation mechanism 65 having such a configuration, when the drive shaft 30 and the drive gear 31 rotate relative to each other by the operation of the drag, the striking pin 70 that cannot rotate with respect to the drive shaft 30 moves to the ring member 64 that rotates with the drive gear 31. The formed sounding recess 71 is repeatedly hit and pronounced.

  Next, the operation of the dual bearing reel will be described.

  When winding the fishing line, the handle 2 is turned in the line winding direction. The rotation of the handle 2 is transmitted from the drive shaft 30 through the drag mechanism 23 to the drive gear 31 and the pinion gear 32 that are linked to the drive shaft 30. The rotation of the pinion gear 32 is transmitted to the spool shaft 20 fitted to the pinion gear 32 by the clutch mechanism 21, and the spool 12 rotates to wind up the fishing line. The rotation of the drive shaft 30 is also transmitted to the traverse cam shaft 46 via the gear member 49 and the gear member 48, and the fishing line guide portion 47 reciprocates along the spool shaft 20 by the rotation of the traverse cam shaft 46. By this reciprocating motion, the fishing line is wound on the spool 12 substantially uniformly.

  On the other hand, when the fishing line is fed out, the clutch lever 17 is operated and the clutch control mechanism 22 releases the clutch mechanism 21. As a result, the engagement between the spool shaft 20 and the pinion gear 32 is released, and the rotation is not transmitted to the rotation transmission mechanism 19 and the drive shaft 30 even if the spool 12 is rotated by feeding the fishing line.

  Next, the operation of the drag mechanism 23 will be described.

When fishing a fish, tension is applied to the fishing line. As a result, a torque is applied to the spool 12 to rotate in the yarn feeding direction. However, while the drag force acting on the spool 12 is smaller than the set drag force, the drive gear 31 is moved by the disc spring 88 compressed by the tightening of the star drag 3 via the first drag washer 63a and the ratchet wheel 61. are sandwiched fine de lugs 62, the driving gear 31 and the drive shaft 30 is relatively non-rotatable. Since the drive shaft 30 is stopped by the reverse rotation prevention mechanism 66 so as not to rotate in the yarn feeding direction, the spool 12 interlocked with the driving gear 31 also does not rotate in the yarn feeding direction. Here, since the second drag washer 63b and the first drag washer 63a are inserted between the ratchet wheel 61 and the drive gear 31 and between the drag plate 62 and the drive gear 31, respectively, the ratchet is applied by the pressing force of the small disc spring 88. The torque that can be transmitted between the wheel 61 and the drag plate 62 and the drive gear 31 can be increased.

  When the tension applied to the fishing line is increased and the torque applied to the spool 12 is increased, a slip is generated at the pressure contact portion of the ratchet wheel 61 and the drag plate 62 and the drive gear 31 via the second drag washer 63b and the first drag washer 63a. . As a result, even if the rotation of the drive shaft 30 is stopped, the drive gear 31 rotates in the yarn unwinding direction while receiving the dynamic friction resistance, and the spool 12 also rotates in the yarn unwinding direction. As described above, when the torque acting on the spool 12 exceeds a predetermined value, in other words, when excessive tension is applied to the fishing line, the drag mechanism 23 is operated to rotate the spool 12 in the line unwinding direction. Protect from tension.

  When the fish 12 is picked up, the sound generation mechanism 65 of the drag mechanism 23 generates a sound when the spool 12 rotates in the line-feeding direction as described above. When the drive shaft 30 and the drive gear 31 rotate relative to each other, the sound generating recess 71 formed in the ring member 64 that rotates in conjunction with the drive gear 31 and the gear member 49 that cannot rotate relative to the drive shaft 30 are interlocked. The rotating hitting pin 70 interferes to generate a click sound. This click sound is a rhythmic sound because it is generated when the heads of the striking pins 70 urged by the coil springs 72 abut on the sound generating recesses 71 arranged at equal intervals. When this sound is generated, the ring member 64 is thin with respect to the second drag washer 63b, and due to the gap between the locking pin 64a and the locking hole 31a, both in the radial direction and in the axial direction. However, it is arranged with some backlash. Thus, since the ring member 64 is not pressed down by other members, the generated sound resonates well and the volume is high.

  When performing jigging, the drag force is frequently adjusted by turning the star drag 3. At this time, the nut member 3 c rotates with respect to the first male screw portion 30 f and the nut member 3 c moves in the axial direction of the drive shaft 30. For example, when the star drag 3 is rotated clockwise in FIG. 2, the nut member 3 c moves in a direction approaching the first one-way clutch 86 and presses the disc spring 88 to increase the drag force. At this time, when the set drag force is large, the star drag 3 may be difficult to turn. However, in the first embodiment, the fluororesin-containing electroless nickel plating film 90 is formed on the surface of the first male screw portion 30f, the sliding resistance of the nut member 3c is reduced, and the nut member 3c rotates smoothly. Thereby, even if drag force becomes large, it becomes possible to operate the star drag 3 with light operation force. In addition, the squeak noise during operation of the star drag 3 is reduced, and the operation feeling is improved.

Second Embodiment
The fishing reel in which the drag mechanism according to the second embodiment is adopted is not a dual-bearing reel but a spinning reel.

It has a lid member 102b (see FIG. 7) made of metal and a hook mounting leg 102c extending obliquely upward and forward from the reel body 102a. The reel body 102a has a space inside, and in that space, the rotor drive mechanism 105 that rotates the rotor 103 in conjunction with the rotation of the handle 101, and the spool 104 is moved back and forth to make the fishing line uniform. And an oscillating mechanism 106 is provided for winding.

  As shown in FIG. 8, the rotor drive mechanism 105 includes a drive gear 111 that rotates together with a drive gear shaft 111 a to which the handle shaft 110 of the handle 101 is fixed, and a pinion gear 112 that meshes with the drive gear 111. The pinion gear 112 is formed in a cylindrical shape, and a front portion 112 a passes through the central portion of the rotor 103 and is fixed to the rotor 103 by a nut 113. The pinion gear 112 has an axially intermediate portion and a rear end portion thereof rotatably supported on the reel body 102a by bearings 114a and 114b mounted on the reel body 102a with a space therebetween.

  The oscillating mechanism 106 is a mechanism for moving the spool 104 in the same direction by moving the spool shaft 115 connected to the center of the spool 104 via the drag mechanism 160 in the front-rear direction. The oscillating mechanism 106 includes a traverse cam shaft 121 arranged in parallel below the spool shaft 115, a slider 122 that moves in the front-rear direction along the traverse cam shaft 121, and an intermediate portion fixed to the tip of the traverse cam shaft 121. And a gear 123. The rear end of the spool shaft 115 is fixed to the slider 122 so as not to rotate. The intermediate gear 123 meshes with the pinion gear 112 directly or indirectly through a reduction mechanism (not shown).

  The spool shaft 115 (an example of the first member) is disposed so as to penetrate the center portion of the pinion gear 112. The spool shaft 115 reciprocates back and forth within the pinion gear 112 by the oscillating mechanism 106. The spool shaft 115 is supported by a bearing 116 having an intermediate portion mounted in the nut 113 and a rear portion by a rear inner peripheral surface of the pinion gear 112 so as to be rotatable and axially movable. Electroless nickel plating is applied to the surface of the spool shaft 115 in order to prevent the spool shaft 115 from biting into the pinion gear 112 when the spool shaft 115 moves back and forth while rotating relative to the pinion gear 112. . As shown in FIGS. 9 and 10, a locking surface 115a for preventing rotation and a male screw portion 115b for drag adjustment are formed at the front end of the spool shaft 115.

On the surface of the male screw portion 115b, as shown schematically in FIG. 11, a fluororesin-containing electroless nickel plating skin layer 190 is formed. In the first embodiment, the fluorine resin-containing nickel plating film is a composite plating film obtained by dispersing and eutecting fluororesin fine particles in a nickel plating solution. However, in the second embodiment, the fluororesin-containing electroless nickel plating film 190 is a composite in which a fluororesin 194 is combined with a porous film 192 of nickel-phosphorus (Ni-P) deposited in a particulate form by heat treatment. It is a plating film. In this case, the cost increases, but the hardness of the composite plating film increases.

Fluororesin 194 used in the fluororesin-containing electroless nickel plating skin layer 190, similarly to the first embodiment, polytetrafluoroethylene (PTFE), poly polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyvinylidene Vinyl fluoride (PVF), perfluoroalkoxy fluororesin (PFA), fluorinated ethylene / hexafluoropropylene copolymer (FEP), ethylene / tetrafluoroethylene copolymer (ETFE), and ethylene / chlorotrifluoroethylene copolymer Selected from the group consisting of polymers (ECTFE). Preferably, the fluororesin 194 is polytetrafluoroethylene (PTFE). The film thickness of the fluororesin-containing electroless nickel plating skin layer 190 is for example in the range of 5μm to 20 [mu] m, preferably in the range from 8μm to 15 [mu] m. The amount of the fluororesin 194 used is, for example, 1.5 to 10 weight percent of the entire plating.

  As shown in FIG. 8, the rotor 103 includes a cylindrical connecting portion 130 and a first rotor arm 131 and a second rotor arm 132 provided on the side of the connecting portion 130 so as to face each other. 133 and a bail arm 134 swingably attached to the rotor main body 133. The rotor body 133 is made of, for example, an aluminum alloy and is integrally formed.

  A front wall 130a is formed at the front portion of the connecting portion 130, and a boss portion 130b is formed at the center of the front wall 130a. A through hole 130c is formed at the center of the boss portion 130b, and the front portion 112a of the pinion gear 112 and the spool shaft 115 pass through the through hole 130c. A nut 113 is disposed on the front portion of the front wall 130a.

The second rotor arm 132 is curved outwardly from the connecting portion 130 and extends forward, and the connecting portion with the connecting portion 130 extends in the circumferential direction of the connecting portion 130 and curves. The second rotor arm 132 has an opening (not shown) for weight reduction.

  As shown in FIG. 8, a reverse rotation prevention mechanism 150 for prohibiting the reverse rotation of the rotor 103 is disposed inside the connecting portion 130 of the rotor 103. The reverse rotation prevention mechanism 150 includes a roller type one-way clutch 151 in which an inner ring rotates freely. The reverse rotation prevention mechanism 150 always prohibits the reverse rotation of the rotor 103 in the yarn feeding direction and does not allow the reverse rotation. Note that the reverse rotation prevention mechanism may be configured to be switched between the reverse rotation prohibition state and the reverse rotation permission state.

  As shown in FIG. 8, the spool 104 is disposed between the first rotor arm 131 and the second rotor arm 132 of the rotor main body 133 and is attached to the tip of the spool shaft 115. As shown in FIG. 9, the spool 104 has a fishing line wound around its outer periphery, for example, an aluminum alloy bobbin trunk 104a, a skirt 104b integrally formed at the rear of the bobbin trunk 104a, and a bobbin trunk 104a. The front flange portion 104c is formed integrally with the front end of the front flange portion 104c. The spool 104 houses a drag mechanism 160 that brakes the spool 104 so that the set drag force acts on the spool 104.

  The bobbin trunk 104 a is a cylindrical member, and the outer peripheral surface is a peripheral surface parallel to the spool shaft 115. The bobbin trunk 104a is formed on a cylindrical portion 104d around which a fishing line is wound, a disc-shaped support wall portion 104e integrally formed on the inner peripheral surface of the cylindrical portion 104d, and an inner peripheral side of the support wall portion 104e. A cylindrical shaft support 104f.

  The skirt portion 104b has a rear flange portion 104h extending in the radial direction from the rear side of the bobbin trunk portion 104a, and a cylindrical portion 104i extending in a cylindrical shape rearward from the outer peripheral side of the rear flange portion 104h. The connecting portion 130 of the rotor 103 is disposed inside the cylindrical portion 104i.

  A metal spool ring 120 for smoothly discharging the fishing line from the bobbin trunk 4a is mounted on the outer peripheral surface of the front flange portion 104c. The spool ring 120 has an inclined surface 120a that widens forward. The spool ring 120 is fixed to the front flange portion 104c by a ring fixing member 119. The ring fixing member 119 is screwed into a cylindrical female screw portion 104j protruding forward from the front flange portion 104c.

  Inside the bobbin trunk 104a, a drag storage cylinder 152 for storing the drag mechanism 160 is attached to the front of the support wall 104e so as to be integrally rotatable. A support cylinder portion 153 for rotatably supporting the spool 104 with respect to the spool shaft 115 by the shaft support portion 104f is mounted in front of the drag storage cylinder portion 152.

  A friction mechanism 162 (to be described later) of the drag mechanism 160 is housed inside the drag housing cylinder portion 152. The drag storage cylinder 152 rotates integrally with the spool 104.

  The support cylinder part 153 is prevented from coming off together with the drag storage cylinder part 152 by a wire rod retaining spring 155 mounted in the spool 104 in front of the support cylinder part 153. The retaining spring 155 is held in the spool 104 by a gap between the front surface of the bobbin trunk 104a and the rear surface of the ring fixing member 119.

  A first support portion 156 and a second support portion 157 to which two bearings 158 a and 158 b for rotatably supporting the spool 104 with respect to the spool shaft 115 are fitted are fitted on the outer peripheral surface of the spool shaft 115. The first support portion 156 is rotatably attached to the spool shaft 115.

As shown in FIG. 12, the second support portion 157 is fixed to the rear portion of the locking surface 115 a formed on the front portion of the spool shaft 115. The second support portion 157 is a large and small two-stage stepped cylindrical member having a small diameter portion 157a and a large diameter portion 157b. An inner ring of a bearing 158b is attached to the small diameter portion 157a. The outer ring of the bearing 158b is attached to the shaft support 104f of the bobbin trunk 104a. The large-diameter portion 157b is formed with a first locking surface 157c configured by planes parallel to each other and a second locking surface 157d orthogonal to the first locking surface 157c. The second support portion 157 is fixed to the spool shaft 115 in a non-rotatable manner by a set screw 159 disposed so as to penetrate the first locking surface 157c. The set screw 159 uses a slotted hollow set screw, and is screwed into a screw hole passing through the locking surface 115a through the first locking surface 157c.

  In the spool 104 having such a configuration, the support cylinder portion 153 is provided in front of the support wall portion 104e of the bobbin trunk portion 104a, and the bearing 158a is disposed on the support cylinder portion 153. Therefore, two bearings are arranged on the shaft support portion 104f. Compared to the configuration of, the axial distance between the two bearings 158a and 158b can be increased. For this reason, the support interval of the spool 104 becomes wide, and shakiness of the spool 104 can be suppressed.

As shown in FIGS. 9 and 10, the drag mechanism 160 is a mechanism for braking the rotation of the spool 104 in the yarn unwinding direction and applying a drag force to the spool 104. Drag mechanism 160 includes a drag knob 161 (an example of a second member), the spool shaft 115 described above, the friction mechanism 162, a fluororesin-containing electroless nickel plating transdermal film 190, and a drag sound mechanism 185. The drag knob 161 is an operation member for adjusting the drag force by hand. The friction mechanism 162 is pressed by the drag knob 161 toward the spool 104 to adjust the drag force. The friction mechanism 162 includes, for example, four drag washers 162a to 162d (an example of a friction plate).

  As shown in FIG. 10, the drag knob 161 includes a first knob member 166 and a knob portion 163 having a second knob member 167 that rotates relative to the first knob member 166, and the first knob member 166 and the second knob. A knob sound generation mechanism (not shown) that generates sound by relative rotation with the member 167.

  In addition to the first knob member 166 and the second knob member 167, the knob portion 163 further includes a connecting member 174 that connects the first knob member 166 and the second knob member 167 so that they cannot move in the axial direction and are rotatable.

  The first knob member 166 is a metal member such as an aluminum alloy having a flange shape having a ring-shaped flange portion 166a and a cylindrical portion 166b having a smaller diameter than the flange portion 166a. The first knob member 166 is provided on the spool shaft 115 so as not to rotate but to move in the axial direction. On the front end surface of the collar portion 166a, a sounding disc 169 constituting a knob sound generation mechanism is provided so as to be integrally rotatable.

  The sound producing disc 169 is a synthetic resin member, and a large number of sound producing recesses 169a are formed on the front surface thereof at intervals in the circumferential direction. A plurality of connection protrusions 169b that fit into a plurality of connection holes 166e formed in the flange portion 166a are formed on the rear surface of the sound emitting disk 169. As a result, the sound disk 169 is prevented from rotating with respect to the first knob member 166.

  An oblong locking slot 166c that engages with the locking surface 115a of the spool shaft 115 in a non-rotatable manner is formed on the inner peripheral portion of the cylindrical portion 166b. The rear end surface of the cylindrical portion 166b contacts the drag washer 162a of the friction mechanism 162 via the first support portion 156.

  The second knob member 167 is disposed to face the first knob member 166 and is provided to be rotatable relative to the first knob member 166. The second knob member 167 is a member that is screwed into the spool shaft 115 and protrudes in a cylindrical shape toward the first knob member 166 so as to cover the flange portion 166a. The second knob member 167 includes a knob body 171, a nut member 172 that is attached to the knob body 171 so as to be non-rotatable and axially movable, and has a female screw portion 172 a that engages with the male screw portion 115 b of the spool shaft 115. 172 and a first knob member 166 are provided with a spring member 173 made of a coil spring disposed in a compressed state.

  The knob body 171 includes a synthetic resin knob body 175 having a disk portion 175a and a cylindrical protrusion 175b having a smaller diameter than the disk portion 175a, and a metal circle fixed to the front surface of the knob body 175. It has a plate-shaped cover part 176 and a metal operation knob 177 fixed to the front surface of the cover part 176 along the radial direction.

  Four bolt members 180 a to 180 d are inserted from the back surface side of the disc portion 175 a of the knob body 175, penetrate the cover portion 176 and screwed into the operation knob 177. Accordingly, the cover portion 176 and the operation knob 177 are fixed to the knob body 175.

  The protruding portion 175 b protrudes in a cylindrical shape toward the first knob member 166 so as to cover the flange portion 166 a of the first knob member 166. The flange portion 166a of the first knob member 166 covered with the protruding portion 175b is prevented from coming off by a connecting member 174 attached to the inner peripheral surface of the protruding portion 175b. Thereby, the 1st knob member 166 and the 2nd knob member 167 are connected so that relative rotation is possible and axial movement is impossible. A nut housing portion 175c in which the nut member 172 is housed so as to be axially movable and integrally rotatable is formed on the inner peripheral portion of the knob body 175.

  The cover portion 176 is formed so as to cover a part of the front surface and the outer peripheral surface of the disc portion 175a of the knob body 175. As a result, the synthetic resin knob body 175 constituting the mechanism of the drag knob 161 is hidden in the spool 104 and is not exposed to the outside. The front surface of the cover portion 176 is recessed so that the thickness gradually decreases toward the center portion. The operation knob 177 is disposed along the diameter of the cover portion 176 and protrudes forward.

  The connecting member 174 is a member formed by bending an elastic metal wire. The connecting member 174 is a C-shaped spring member having four corners corresponding to substantially square corners. The connecting member 74 is mounted on the inner peripheral surface of the projecting portion 175b by engaging the corner portion with an annular groove formed on the inner peripheral surface of the projecting portion 175b. The connecting member 174 prevents the flange portion 166a from coming off by the three arc portions between the corner portions coming into contact with the rear surface of the flange portion 166a.

  The nut member 172 is, for example, a hexagonal nut, and is screwed into a male screw portion 115 b formed on the outer peripheral surface of the spool shaft 115, and compresses the spring member 173 in accordance with the rotation of the knob body 175.

  When the second knob member 167 and the first knob member 166 rotate relative to each other during the drag operation, the knob sound generation mechanism repeatedly generates a collision with the sound output recess 169a.

  As shown in FIGS. 9 and 12, the drag washer 162 a of the friction mechanism 162 is a metal circle that contacts the first knob member 166 via the first support portion 156 and cannot rotate with respect to the spool shaft 115. It is a plate member. The drag washer 162 b is a metal disk member that can rotate integrally with the spool 104. The drag washer 162c is a metal disk member that cannot rotate with respect to the spool shaft 115, like the drag washer 162a. The drag washer 162 d is a disc member made of, for example, felt or graphite that is rotatable with respect to the spool 104 and the spool shaft 115. An oblong locking slot 162e that engages with a locking surface 115a formed on the front end side of the spool shaft 115 is formed at the center of the drag washers 162a and 162c. On the outer peripheral surface of the drag washer 162b, a plurality of (for example, eight) ears 162f projecting radially outward are formed. The ears 162f are arranged on the inner peripheral surface of the drag storage cylinder 152 at intervals in the circumferential direction, and are locked by a plurality of locking recesses 152a formed along the axial direction. As a result, the drag washer 162 b can rotate integrally with the spool 104.

  The drag washers 162a to 162d are prevented from being detached by the first support portion 156 that supports the support cylinder portion 153. Accordingly, the drag washers 162a to 162d cannot be attached or detached unless the retaining spring 155 disposed in front of the support cylinder portion 153 is removed.

The drag sound generation mechanism 185 is a mechanism that generates a sound when the spool shaft 115 and the spool 104 rotate relative to each other by the operation of the drag. As shown in FIG. 12, the drag sound generation mechanism 185 repeatedly hits the first sound generation member 186 and the first sound generation member 186 that is attached to the back surface of the rear flange portion 104 h of the spool 104 and rotates together with the spool 104. A second sounding member 187.

  The first sounding member 186 is a metal member having a cylindrical shape with a hook and having a plurality of arcuate sound emitting recesses 186a formed on the inner peripheral surface. A name plate 188 is disposed on the rear surface of the first sounding member 186, and the first sounding member 186 together with the name plate 188 is screwed to the back surface of the rear flange portion 104h.

  The second sounding member 187 includes two striking pins 187a that advance and retreat toward the sound output recess 186a, and two spring members 187b that bias the two striking pins 187a toward the sound output recess 186a. The striking pin 187a is housed in a tubular housing member 189 that is non-rotatably engaged with the second locking surface 157d of the second support portion 157. The storage member 189 has a thick cylindrical storage body 189a having two storage grooves 189c for storing the striking pin 187a so as to be able to advance and retreat, and is screwed to the storage body 189a to close the storage groove 189c. And a disc-shaped cover 189b that engages with the locking surface 157d. The two storage grooves 189c of the storage main body 189a are opened in the outer peripheral surface of the storage main body 189a, and are formed so that the interval between the two storage grooves 189c on the opening side is narrow. A locking slot 189d that engages with the second locking surface 157d is formed on the inner peripheral surface of the cover 189b. A washer 201 is disposed between the storage member 189 and the support wall portion 104 e of the spool 104.

  On the rear surface of the cover 189b, for example, three spool position adjusting washers 202 made of, for example, synthetic resin, which are engaged with the first locking surface 157c of the second support portion 157, and 2 for restricting rearward movement of the spool 104. A sheet of restricting washers 203 and 204 is attached. The restricting washers 203 and 204 are formed with locking slots 203 a and 204 a that engage with the locking surface 115 a of the spool shaft 115 in the inner peripheral portion, and are not rotatable with respect to the spool shaft 215. The restriction washer 204 is a stepped washer, and holds the seal member 205 with the restriction washer 203. The outer peripheral portion of the seal member 205 is in contact with the inner peripheral surface of the first sounding member 186. The seal member 205 is provided to prevent the liquid from flowing into the spool 104 including the friction mechanism 162 from the rear surface of the spool 104.

[Reel operation and operation]
Adjust the drag force according to the size and type of fish before fishing. To adjust the drag force, the drag knob 161 is turned. When the drag knob 161 is rotated, for example, clockwise, the first knob member 166 is pressed toward the friction mechanism 162 via the spring member 173 by the nut member 172 screwed into the spool shaft 115. This increases the drag force. At this time, a light click sound with good crispness is generated by the relative rotation of the first knob member 166 and the second knob member 167.

  At the time of casting, the bale arm 134 is reversed to the yarn releasing posture. As a result, the fishing line can be released from the spool 104. In this state, the fishing rod is cast while hooking the fishing line with the index finger of the hand holding the fishing rod. The fishing line is then released vigorously due to the weight of the device. When the handle 101 is rotated in the line winding direction in this state, the rotor 103 is rotated in the line winding direction by the rotor driving mechanism 105, the bail arm 134 is returned to the line winding position by the bail reversing mechanism (not shown), and the fishing line. Is wound around the spool 104 by the bail arm 134.

When jigging is performed, a situation may arise in which the drag force needs to be adjusted according to the fish that is picked up during winding. In this case, since the fluorine resin-containing electroless nickel plating skin layer 190 on the surface of the external thread portion 115b of the spool shaft 115 is formed, the sliding performance is increased with the drag knob 161. For this reason, even if the drag force is increased, the drag knob 161 can be operated with a light operation force.

<Features>
The above embodiment can be expressed as follows.

  (A) The fishing reel drag mechanism 23 (or 160) is a mechanism that brakes the rotation in the line-feeding direction of the spool 12 (or 104) for winding the fishing reel. The fishing reel drag mechanism 23 (or 160) includes a drive shaft 30 (or spool shaft 115) having a first male thread portion 30f (or 115b), a star drag 3 (or drag knob 161), and a friction mechanism 4 ( Or 162) and a fluororesin-containing electroless nickel plating film 90 (or 190). The star drag 3 (or drag knob 161) has a female screw portion 3d (or 172a) that is screwed into the first male screw portion 30f (or 115b). The friction mechanism 4 (or 162) changes the frictional force by relatively rotating the star drag 3 (or drag knob 161) and the drive shaft 30 (or spool shaft 115), and the spool 12 (or 104). This mechanism is capable of braking the rotation in the yarn unwinding direction. The fluororesin-containing electroless nickel plating film 90 (or 190) is formed on at least one of the first male screw portion 30f (or male screw portion 115b) and the female screw portion 3d (or 172a).

  In the drag mechanism 23 (or 160), one of the drive shaft 30 (or the spool shaft 115) as the first member and the star drag 3 (or the drag knob 161) as the second member is used as an operation member, and relative to the other member. By rotating, the frictional force of the friction mechanism 4 (or 162) changes, and the drag force can be adjusted. At least one of the first male screw portion 30f (or 115b) of the drive shaft 30 (or the spool shaft 115) and the female screw portion 3d (or 172a) of the star drag 3 (or drag knob 161) does not contain fluorine resin. Electrolytic nickel plating film 90 (or 190) is formed. For this reason, the film thickness of the fluororesin-containing electroless nickel plating film 90 (or 190) becomes uniform, and sliding between the first male screw portion 30f (or 115b) and the female screw portion 3d (or 172a) that rotate relative to each other is achieved. The resistance is reduced, and the relative rotation between the first male screw portion 30f (or 115b) and the female screw portion 3d (or 172a) becomes smooth. Thereby, even if the drag force increases, the operation member can be operated with a light operation force. Moreover, the squeak noise during operation of the star drag 3 (or drag knob 161) is reduced, and the operation feeling is improved.

  (B) In the fishing reel drag mechanism 23 (or 160), the fluororesin is polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF). , Perfluoroalkoxy fluororesin (PFA), fluorinated ethylene / hexafluoropropylene copolymer (FEP), ethylene / tetrafluoroethylene copolymer (ETFE), and ethylene / chlorotrifluoroethylene copolymer (ECTFE) May be selected from the group consisting of In this case, a fluororesin having a particularly high slidability can be selected.

  (C) In the fishing reel drag mechanism, the fishing reel may be a double-bearing reel 100 or a single-bearing reel in which the spool 12 is rotated by the rotation of the handle 2. The first member is a drive shaft 30 that rotates as the handle 2 rotates. The second member is a star drag 3 that is screwed onto the drive shaft 30. The friction mechanism 4 has at least one drag plate 62 disposed on the drive shaft 30 and pressed by the star drag 3. In this case, the drag plate 62 is disposed around the drive shaft. In the double-bearing reel 100 or the single-bearing reel having the drag mechanism 23, the star drag 3 can be operated with a light operating force even if the drag force increases.

  (D) The double-bearing reel drag mechanism 23 may further include a reverse rotation prevention mechanism 66 that prohibits rotation of the drive shaft 30 in the yarn unwinding direction. In this case, since the drive shaft 30 does not rotate in the yarn feeding direction, the star drag type drag mechanism 23 can be configured by providing the drag plate 62 so as to be integrally rotatable with at least the drive shaft 30.

  (E) In the fishing reel drag mechanism 160, the fishing reel is the spinning reel 200 that winds freely around the spool shaft 115. The first member is a spool shaft 115 on which the spool 104 is rotatably mounted. The second member is a drag knob 161 that is screwed onto the spool shaft 115. The friction mechanism 162 includes at least one drag washer 162a to 162d disposed on the spool shaft 115 and pressed by the drag knob 161. In this case, in the spinning reel in which the drag washers 162a to 162 are arranged around the spool shaft 115, the drag knob 161 can be operated with a light operating force even if the drag force increases.

  (F) In the fishing reel drag mechanism 23 (or 160), the fluororesin-containing electroless nickel plating film 90 (or 190) may be formed on the first male screw portion 30f (or the male screw portion 115b). In this case, since the fluororesin-containing electroless nickel plating film 90 (or 190) is formed on the first male thread portion 30f (or the male thread portion 115b), the fluororesin-containing electroless nickel is adjusted according to the drag force adjustment position. The contact position between the plating film 90 (or 190) and the female screw portion 3d (or 172a) changes. For this reason, the lifetime of the fluororesin-containing electroless nickel plating film 90 (or 190) can be extended.

  (G) In the fishing reel drag mechanism 23, the fluororesin-containing electroless nickel plating film 90 may be a composite plating film in which fluororesin fine particles are dispersed and co-deposited. In this case, the fluororesin-containing electroless nickel plating film 90 can be formed while suppressing an increase in cost.

  (H) In the fishing reel drag mechanism 160, the fluororesin-containing electroless nickel plating film 190 is a composite of nickel-phosphorus (Ni-P) porous film deposited in a particulate form by heat treatment. A composite plating film may be used. In this case, the formation cost of the composite plating film increases, but the hardness of the composite plating film increases.

<Other embodiments>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention. In particular, a plurality of embodiments and modifications described in this specification can be arbitrarily combined as necessary.

  (A) In the first and second embodiments, as the drag mechanism, the star drag mechanism of the dual-bearing reel and the front drag mechanism of the spinning reel are exemplified, but the drag mechanism of the present invention is not limited to this. For example, the present invention can also be applied to a rear drag mechanism of a spinning reel, a lever drag mechanism of a dual bearing reel, and a drag mechanism of a single bearing reel in which a handle is provided on a spool.

  (B) In 1st and 2nd embodiment, although the fluororesin containing electroless nickel plating film is formed in the drive shaft or spool shaft which is a 1st member, this invention is not limited to this. For example, you may provide a fluororesin containing electroless nickel plating film in the internal thread part provided in the star drag or drag knob which is the 1st member.

  (C) Instead of the nickel plating film in which the fluororesin is dispersed and co-deposited according to the first and second embodiments, a nickel-phosphorus plating film or a nickel-boron plating film in which the fluororesin is dispersed and co-deposited may be used. . However, in this case, the cost for forming the composite plating film increases.

  (D) In the above embodiment, polytetrafluoroethylene (PTFE) is exemplified as the fluororesin, but the present invention is not limited to this. Fluororesin is polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), perfluoroalkoxy fluororesin (PFA), fluorinated ethylene hexafluoride Any material selected from the group consisting of propylene copolymer (FEP), ethylene / tetrafluoroethylene copolymer (ETFE), and ethylene / chlorotrifluoroethylene copolymer (ECTFE) Good.

(E) In both the first embodiment and the second embodiment, the first male screw portion 30f (or the male screw portion 115b) of the drive shaft 30 (or the spool shaft 115), which is the first member, is fluorinated resin-containing electroless nickel plated. to form a skin layer 90 (or 190), but the present invention is not limited thereto. The female screw portion 3d of the nut member 3c is a second member (or 172) (or 172a) may be formed fluororesin-containing electroless nickel plating epithelial membrane. It is also possible to form both the fluororesin-containing electroless nickel plating skin layer of the first male threaded portion 30f (or the male screw section 115b) and the female screw portion 3d (or 172a).
