Description

Towing mechanism for fishing reel

The present invention relates to a towing device, and more particularly to a towing mechanism for a fishing reel that can adjust a drag force by rotating a fishing line of a winding reel for a fishing reel in a direction in which the fishing line is repeatedly fed.

In the fishing reel, in order to adjust the drag force, a towing mechanism for rotating the reel of the reel in the direction in which the reel is repeatedly fed is provided. The conventional towing mechanism has an operating member for adjusting the dragging force, a screw member for screwing the operating member, and a friction mechanism for changing the frictional force by rotating the operating member. For example, in a double-bearing reel or a single-bearing reel that winds a fishing line by a rotating reel, the operating member is screwed to a drive shaft or a reel shaft as a screw member. In the spinning reel which winds the fishing line around the stationary reel by the rotor, the operating member is screwed to the reel shaft as the screw member (see, for example, Patent Document 1).

In the conventional towing mechanism, the turning operation of the operating member causes the screwing portion of the operating member to move toward the axial direction of the screw member, and by this movement, the frictional force of the friction mechanism is changed, and the drag force can be adjusted.

In the conventional towing mechanism, when the operating member is rotated, the turning operation of the operating member may be changed. In particular, in the case of jigging fishing, it is necessary to frequently drag the paper, and when a large drag force is set, such a phenomenon is likely to occur.

An object of the present invention is to provide a towing mechanism for a fishing reel that can operate an operating member with a light operating force even if the drag force is increased.

The towing mechanism of the fishing reel is a mechanism that can rotate the fishing line of the winding reel of the fishing reel in a reverse direction. The towing mechanism of the fishing reel includes a first member having a male screw portion, a second member, a friction mechanism, and an electroless nickel plating film of a fluorine resin. The second member has a female screw portion that is screwed to the male screw portion. The friction mechanism is a mechanism that allows the first member and the second member to rotate relative to each other, thereby changing the frictional force to brake the reel of the reel in the feeding direction. The electroless nickel plating film of the fluorine resin is formed at least in the male thread portion and the female thread portion Any of them.

In this drag mechanism, one of the first member and the second member is used as an operation member to rotate relative to the other member, whereby the frictional force of the friction mechanism is changed, and the drag force can be adjusted. At least one of the male screw portion of the first member and the female screw portion of the second member is formed with an electroless nickel plating film of a fluorine resin. Therefore, the film thickness of the electroless nickel plating film of the fluorine resin is uniform, and the sliding resistance between the male screw portion and the female screw portion which are relatively rotated becomes small, and the relative rotation between the male screw portion and the female screw portion becomes smooth. Thereby, even if the drag force becomes large, the operation of the operating member can be performed with a light operating force. Moreover, the scratching sound in the operation of the operating member becomes small, and the feeling of operation is improved.

In the towing mechanism of the fishing reel, the fluororesin may also be derived from polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyfluorinated diethylene (PVDF), polyvinyl fluoride (PVF), perfluorocarbon. Selection of a group consisting of alkoxy resin (PFA), tetrafluoroethylene-hexafluoropropylene copolymer (FEP), ethylene-tetrafluoroethylene copolymer (ETFE) and ethylene-chlorotrifluoroethylene copolymer (ECTFE) . In this case, a resin having high slidability can be selected among the fluororesins.

In the towing mechanism of the fishing reel, the fishing reel can be a double-bearing reel or a single-bearing reel that rotates the reel by rotation of the handle. The first member is a drive shaft that is rotated by the rotation of the handle. The second member is an operating member screwed to the drive shaft. The friction mechanism has a friction plate disposed on the drive shaft and pressed by at least one of the operating members. In this case, there is a towing mechanism having a friction plate disposed around the drive shaft. The double-bearing reel or the single-bearing reel can operate the operating member with a light operating force even if the drag force is large.

Further, the towing mechanism of the fishing reel may further include a reverse rotation preventing mechanism that prohibits the rotation of the fishing line in the reverse feeding direction of the drive shaft. In this case, since the drive shaft does not rotate in the direction in which the fishing line is repeatedly fed, the drag mechanism can be configured to be integrally rotatable on the drive shaft, thereby forming a drag mechanism in a star-shaped drag configuration.

In the towing mechanism of the fishing reel, the fishing reel may be a spinning reel that is rotatably wound around the reel shaft. The first member is a spool shaft to which the spool is rotatably mounted. The second member is an operating member screwed to the spool shaft. The friction mechanism includes a friction plate disposed on the spool shaft and pressed by at least one of the operating members. In this case, in the spinning reel in which the friction plate is disposed around the spool shaft, the operation member can be operated with a light operating force even if the drag force is large.

In the towing mechanism of the fishing reel, an electroless nickel plating film of a fluorine resin may be formed in the male screw portion. In this case, since the electroless nickel plating film of the fluorine resin is formed in the male screw portion of the first member, the contact position of the electroless nickel plating film of the fluorine resin and the female screw portion changes depending on the adjustment position of the drag force. . Further, therefore, it is possible to extend the life of the electroless nickel plating film of the fluorine resin.

In the towing mechanism of the fishing reel, the electroless nickel plating film of the fluorine resin may be a composite plating film in which fine particles of the fluororesin are dispersed and eutectoid. In this case, it is possible to suppress an increase in cost and form an electroless nickel plating film of a fluorine-containing resin.

In the towing mechanism of the fishing reel, the electroless nickel plating film of the fluorine resin may be a composite plating of a nickel-phosphorus (Ni-P) porous film which is composited by precipitation into a particulate form by heat treatment. Membrane. In this case, although the cost of forming the composite plating film is high, the hardness of the composite plating film is high.

According to the present invention, the sliding resistance between the male screw portion and the female screw portion which are relatively rotated can be made small, and the relative rotation between the male screw portion and the female screw portion can be made smooth. Thereby, even if the drag force becomes large, the operation of the operating member can be performed with a light operating force.

The throwing control mechanism 24 adjusts the resistance when the spool 12 rotates.

The spool 12 is fixed to a spool shaft 20 that passes through its center. The spool shaft 20 is rotatably supported by the cord reel body 1 by bearings.

As shown in FIG. 3, the clutch lever 17 is disposed behind the spool 12 at a rear portion between the first side plate 8 and the second side plate 9. The clutch lever 17 is slidable in the vertical direction between the first side plate 8 and the second side plate 9. The engagement shaft 17a penetrates the second side plate 9 and is integrally formed on the handle mounting side of the clutch lever 17. This engagement shaft 17a is engaged with the clutch control mechanism 22.

As shown in FIG. 3, the uniform winding mechanism 18 has a traverse cam shaft 46 which is disposed between the first side plate 8 and the second side plate 9 in front of the reel 12 and has an intersecting spiral groove 46a formed on the outer peripheral surface thereof. And a fishline guide portion 47 that reciprocates in the spool axis direction by the traverse camshaft 46.

The rotation transmission mechanism 19 includes a drive shaft 30 (an example of a first member), a drive gear 31 fixed to the drive shaft 30, a cylindrical pinion 32 meshed with the drive gear 31, and a rotator cam shaft that is non-rotatably mounted The gear member 48 at the right end of FIG. 3; and the gear member 49 that is non-rotatably mounted to the base end portion of the drive shaft 30.

The drive shaft 30 is, for example, a metal shaft member made of a stainless steel alloy. As shown in FIGS. 4 and 5, the drive shaft 30 has a shaft support portion 30a, a first engagement portion 30b, a flange portion 30c, a second engagement portion 30d, and a third card, respectively, from the proximal end side toward the distal end side. The stopper portion 30e, the first male screw portion 30f, the second male screw portion 30g, and the fourth locking portion 30h. A bearing 28 is attached to the shaft support portion 30a. The first locking portion 30b has a larger diameter than the shaft support portion 30a, and is formed by two sets of chamfered portions that are parallel to each other. The crotch portion 30c is larger than the first locking portion 30b. The second locking portion 30d is formed to have a smaller diameter than the crotch portion 30c, and is formed by two sets of chamfered portions that are parallel to each other. The third locking portion 30e is formed to have a smaller diameter than the second locking portion 30d, and is constituted by a pair of chamfered portions that are parallel to each other. The first male screw portion 30f is formed on the outer peripheral surface of the third locking portion 30e except for the third locking portion 30e. The second male screw portion 30g is formed on the front end of the drive shaft 30 with a smaller diameter than the first male screw portion 30f. unit. The fourth locking portion 30h is formed on the outer circumferential surface of the drive shaft 30 in which the second male screw portion 30g is formed. The handle 2 is rotatably attached to the fourth locking portion 30h, and the handle 2 is fixed to the drive shaft 30 by a nut 43 that is screwed into the second male screw portion 30g.

On the surface of the first male screw portion 30f, as shown schematically in Fig. 6, an electroless nickel plating film 90 of a fluorine-containing resin is formed. In addition, the shape of the screw is abbreviate|omitted and FIG. The electroless nickel plating film 90 of the fluorine-containing resin is a composite plating film formed by dispersing the fine particles of the fluororesin substantially uniformly in the nickel plating solution. The fluororesin used for the electroless nickel plating film 90 of the fluorine resin may be derived from polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyfluorinated diethylene (PVDF), and polyvinyl fluoride (PVF). ), a perfluoroalkoxy resin (PFA), a tetrafluoroethylene-hexafluoropropylene copolymer (FEP), an ethylene-tetrafluoroethylene copolymer (ETFE), and an ethylene-chlorotrifluoroethylene copolymer (ECTFE) Select from the group. It is preferably a fluororesin-based polytetrafluoroethylene (PTFE). In addition, in FIG. 6, the fluororesin is shown typically in the dot shape. The film thickness of the electroless nickel plating film 90 of the fluorine-containing resin is, for example, in the range of 2 μm to 20 μm, and preferably in the range of 5 μm to 15 μm. The amount of eutectic of the fluororesin is, for example, 1.5 to 10% by weight based on the entire plating solution.

The drive shaft 30 is rotatably attached to the reel body 1, and 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 prohibit rotation of the fishing line in the reverse feed direction. (reverse). Further, the drive shaft 30 is rotatably supported by the second side cover 7 and the frame 5 via 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 disposed in 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 wheel 86a that is non-rotatably attached to the second side cover 7, a inner wheel 86b that is rotatably mounted to the drive shaft 30, and is disposed between the outer wheel 86a and the inner wheel 86b. Roller 86c.

The second one-way clutch 87 includes a ratchet 61 and a ratchet pawl 67 (see FIG. 5) that is swingably attached to the outer side surface of the second side plate 9 of the reel body 1. The ratchet 61 is attached to the second locking portion 30d so as not to be rotatable between the drive gear 31 and the gear member 49. The ratchet 61 is disposed in contact with the crotch portion 30c, and the crotch portion 30c is restricted from moving toward the proximal end side. The ratchet teeth 61a which are formed in a substantially parallelogram shape on the outer peripheral portion of the ratchet 61 are disposed at intervals in the circumferential direction. The ratchet pawl 67 that is rotatably attached to the reel body 1 is engaged with the ratchet teeth 61a, and the rotation of the fishing line of the drive shaft 30 in the reverse feed direction is prohibited. The second one-way clutch 87 functions as a friction plate of the towing mechanism 23 .

The drive gear 31 is rotatably attached to the drive shaft 30, and is coupled to the towing mechanism 23 via the drive shaft 30. The towing mechanism 23 brakes the rotation of the fishing line of the reel 12 in the reverse feeding direction by the rotation of the fishing line of the brake driving gear 31 in the direction in which the fishing line is repeatedly fed.

As shown in FIG. 3, the pinion gear 32 is a cylindrical member that extends inward from the outer side of the second side plate 9 and penetrates the spool shaft 20 at the center. The pinion gear 32 is attached to the spool shaft 20 so as to be freely movable in the axial direction. At the left end of the pinion 32 of Fig. 3, a card for passing through the spool shaft 20 in the radial direction The meshing groove 32a of the pin 20b is engaged. The clutch mechanism 21 is constituted by the engagement groove 32a and the engagement pin 20b attached to the spool shaft 20. Further, a reduced diameter portion 32b is formed in the intermediate portion of the pinion gear 32, and a gear portion 32c that is meshed 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 reduced diameter portion 32b.

The gear member 49 is rotatably attached to the first locking portion 30b formed at the proximal end portion of the drive shaft 30, and abuts against the crotch portion 30c from the proximal end side. The gear member 48 mounted on the traverse camshaft 46 is meshed with the gear member 49 mounted on the drive shaft 30. With such a configuration, the traverse cam shaft 46 of the uniform winding mechanism 18 rotates in conjunction with the rotation of the drive shaft 30 in the line winding direction.

The drag mechanism 23 is a mechanism that rotates the drive shaft 30 in synchronization with the drive gear 31 until the set drag force is reached, and the fishing line of the brake drum 12 is repeatedly rotated in the feed direction. The drag force is adjusted by the tightening of the star fishing valve 3. As shown in FIGS. 4 and 5, the drag mechanism 23 includes a star fishing force valve 3, a drive shaft 30, a friction mechanism 4, and an electroless nickel plating film 90 of the fluorine-containing resin formed on the drive shaft 30 ( Refer to Figure 6). Further, the towing mechanism 23 includes a sounding mechanism 65 and the above-described reverse rotation preventing mechanism 66.

As shown in FIG. 3, the star-shaped fishing valve 3 includes a main body portion 3b having a plurality of radially operated operation portions 3a, and a screw that is integrally rotatable and movable in the axial direction and disposed in the main body portion 3b. Cap member 3c. The nut member 3c has a female screw portion 3d screwed to the first male screw portion 30f. The star-shaped fishing valve 3 is used for pressing on the base side of the ball An operating member that drives the friction mechanism 4 of the shaft 30 to adjust a predetermined drag force. Four disc-shaped springs 88 are mounted between the star fishing valve 3 and the first one-way clutch 86. The disc spring 88 is used to smoothly convey the locking force of the star fishing valve 3 to the tow plate 62 to be described later. The disc spring 88 is disposed between the nut member 3c of the star fishing valve 3 and the inner wheel 86b of the first one-way clutch 86.

The star fishing force valve 3 can adjust the degree of locking so that the inner wheel 86b of the first one-way clutch 86 that mounts the drive shaft 30 to the second side cover 7 can pass through the disc spring 88 (refer to FIG. 3). ) Move in the direction of the axis. That is, the pressing force of the disk spring 88 is adjusted by the rotation of the star fishing force valve 3. Thereby, the drag force can be finely adjusted by the star fishing force valve 3.

The friction mechanism 4 includes a tow plate 62 (an example of a friction plate) that is integrally rotatably engaged with the drive shaft 30, and a ratchet 61 (an example of a friction plate). The tow plate 62 is in contact with the disk member of the drive gear 31 (an example of the second friction plate) from the handle 2 side via the first drag washer 63a. The trailing plate 62 is attached to the third locking portion 30e so as to be rotatable integrally with the drive shaft 30. The tow plate 62 is coupled to the ratchet 61 to hold the drive gear 31. Further, the trailing plate 62 is coupled to the inner ring 86b of the first one-way clutch 86 so as not to be rotatable. As a result, the inner ring 86b of the first one-way clutch 86 integrally rotates the drive shaft 30, and transmits the pressing force of the star fishing valve 3 to the tow plate 62. In the center portion of the tow plate 62, an engagement hole 62a is formed in which the inner ring 86b is integrally rotatable and the third locking portion 30e of the drive shaft 30 is rotatably engaged. Drive gear 31 The ratchet 61 is contacted via the second trailing washer 63b.

The second trailing washer 63b is a friction disc that is disposed between the ratchet 61 and the drive gear 31 and has an annular shape. An annular member 64 is disposed on the inner peripheral side of the second trailing washer 63b. The annular member 64 is free to rotate the drive shaft 30. Further, the annular member 64 has a locking pin 64a on the side of the drive gear 31. The locking pin 64a is engaged with the side surface of the through driving gear 31 to form one of the pair of locking holes 31a, 31b. As a result, the annular member 64 rotates in conjunction with the drive gear 31. The thickness of the annular member 64 is thinner than the thickness of the second trailing washer 63b. Therefore, the drag plate 62 is pressed by the star fishing force valve 3, and the drive gear 31 is held by the trailing plate 62 and the ratchet 61, and the pressing force does not act on the ring member 64 to be freely rotatable.

The sounding mechanism 65 has a striking pin 70 that is detachably attached to the gear member 49 in the direction of the drive shaft, and a plurality of sounding concave portions that are formed on the side opposite to the handle side of the annular member 64 at intervals in the circumferential direction. 71; a coil spring 72 that pushes the strike pin 70 toward the ring member 64. The striking pin 70 has a head that is engaged with the sounding concave portion 71 at the front end. The striker pin 70 and the coil spring 72 are housed in a cylindrical portion 49a that is formed to protrude toward the side surface on the handle side of the gear member 49. The cylindrical portion 49a has a size that is inserted into the through hole 61b formed in the vicinity of the center hole of the ratchet 61, and is exposed on the side of the annular member 64. A plurality of sound-emitting recesses 71 are formed on the side surface of the annular member 64 that faces the striking pin 70 at intervals in the circumferential direction. In the sounding mechanism 65 of such a configuration, when the drive shaft 30 and the drive gear 31 are relatively rotated by the action of the drag force, the strike pin 70 that cannot rotate the drive shaft 30 is formed in a ring shape that rotates together with the drive gear 31. Structure The sound concave portion 71 of the member 64 repeatedly collides and sounds.

Next, the operation of this double bearing reel will be described.

When the fishing line is to be taken up, the handle 2 is rotated in the direction in which the fishing line is taken up. The rotation of the handle 2 is transmitted from the drive shaft 30 via the drag mechanism 23 to the drive gear 31 and the pinion gear 32 that are interlocked with 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, so that the spool 12 is rotated to take up the fishing line. The rotation of the drive shaft 30 is also transmitted to the traverse camshaft 46 via the gear member 49 and the gear member 48, and the fishline guide portion 47 reciprocates along the spool shaft 20 by the rotation of the traverse camshaft 46. By this reciprocating motion, the fishing line is wound evenly to the reel 12.

Further, when the fishing line is repeatedly fed, the clutch lever 17 is operated, and the clutch mechanism 21 is disengaged by the clutch control mechanism 22. Thereby, the fitting of the spool shaft 20 and the pinion gear 32 is released, and even if the fishing line is repeatedly fed and the spool 12 is rotated, the rotation is not transmitted to the rotation transmitting mechanism 19 and the drive shaft 30.

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

When the fish is caught, the tension is applied to the fishing line. Therefore, the torque to be rotated in the direction in which the fishing line is repeatedly sent to the fishing line acts on the reel 12. However, when the drag force acting on the spool 12 is smaller than the set drag force, the disc gear spring 88 compressed by the locking of the star fishing valve 3 causes the drive gear 31 to pass the first drag. The washer 63a is held by the ratchet 61 and the second trailing plate 62, so that the drive gear 31 and the drive shaft 30 cannot rotate relative to each other. Also, since the drive shaft 30 is fixed by the reverse rotation preventing mechanism 66 Since the fishing line does not rotate in the direction in which the fishing line is repeatedly fed, the reel 12 that is interlocked with the driving gear 31 does not rotate in the direction in which the fishing line is repeatedly fed. Here, since the second drag washer 63b and the first trailing washer 63a are inserted between the ratchet 61, the drive gear 31, the trailing plate 62, and the drive gear 31, the small disc spring 88 can be pressed. The pressure increases the torque that can be transmitted between the ratchet 61 and the trailing plate 62 and the drive gear 31.

When the tension applied to the fishing line becomes high and the torque applied to the spool 12 becomes large, the ratchet 61 and the trailing plate 62 and the crimping portion of the drive gear 31 via the second drag washer 63b and the first trailing washer 63a are generated. Slip. As a result, even if the rotation of the drive shaft 30 is stopped, the drive gear 31 rotates in the direction in which the fishing line is repeatedly fed while receiving the impedance of the dynamic friction, and the spool 12 also rotates in the direction in which the fishing line is repeatedly fed. Thus, when the torque for the reel 12 exceeds a predetermined value, in other words, when an excessive tension is applied to the fishing line, the towing mechanism 23 is actuated and the reel 12 is rotated in the direction in which the fishing line is repeatedly fed, thereby protecting the fishing line from being excessively large. The tension is damaged.

When the fish is pulled up, as described above, when the reel 12 is rotated in the direction in which the fishing line is repeatedly fed, the sounding mechanism 65 of the towing mechanism 23 emits a sound. When the drive shaft 30 and the drive gear 31 rotate relative to each other, the sound concave portion 71 formed in the annular member 64 that rotates in conjunction with the drive gear 31 and the gear member 49 that does not rotate relative to the drive shaft 30 are rotated. The pins 70 interfere with each other to make a click. Since the click sound is generated by intermittently abutting the head of the striking pin 70 which is pushed by the coil spring 72 against the sounding concave portion 71 which is disposed at equal intervals, it is a rhythmic sound. When the sound is generated, the annular member 64 is present to the second drag washer 63b. Since it is thin, the gap between the locking pin 64a and the locking hole 31a is arranged in a state having a certain gap regardless of the radial direction or the radial direction. Thus, since the annular member 64 is not pressed by other members, the sound emitted is loud and the volume is large.

Moreover, in the case of performing the jigging fishing method, the star fishing force valve 3 is rotated to frequently adjust the drag force. At this time, the nut member 3c rotates the first male screw portion 30f, and the nut member 3c moves in the axial direction of the drive shaft 30. For example, when the star fishing valve 3 is rotated in the clockwise direction of FIG. 2, the nut member 3c moves in a direction approaching the first one-way clutch 86, and the disc spring 88 is pressed to increase the drag force. At this time, when the set drag force is large, the star fishing force valve 3 may not easily rotate. However, in the first embodiment, the electroless nickel plating film 90 of the fluorine resin is formed on the surface of the first male screw portion 30f, so that the sliding resistance of the nut member 3c is reduced, and the nut member 3c can be smoothly rotated. Thereby, even if the drag force becomes large, the operation of the star fishing force valve 3 can be performed with a light operating force. Further, the scratching sound in the operation of the star fishing force valve 3 becomes small, and the feeling of operation is improved.

A coupling portion 130 of the rotor 103 is disposed inside the cylindrical portion 104i.

A metal reel ring 120 that smoothly discharges the fishing line from the bobbin main body portion 4a is attached to the outer peripheral surface of the front flange portion 104c. The spool ring 120 has an inclined surface 120a whose front end is enlarged. 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 to a cylindrical female screw portion 104j that protrudes forward from the front flange portion 104c.

Inside the winding main body portion 104a, the towing housing portion 152 for accommodating the drag mechanism 160 is rotatably mounted in front of the support wall portion 104e. A support cylinder portion 153 for supporting the spool 104 to the spool shaft 115 so as to be rotatable together with the shaft support portion 104f is attached to the front side of the towing storage cylinder portion 152.

A friction mechanism 162, which will be described later, of the drag mechanism 160 is housed inside the towing storage tube portion 152. The tow storage cylinder portion 152 rotates integrally with the spool 104.

The support tube portion 153 is prevented from being detached together with the towed storage tube portion 152 by a wire-made detachment prevention spring 155 attached to the inside of the reel 104. The detachment preventing spring 155 is held in the spool 104 in a gap between the front surface of the winding main body portion 104a and the rear surface of the ring fixing member 119.

Therefore, two windings are arranged in the shaft support portion 104f. The structure of the bearing can expand two bearings 158a, The spacing of the 158b in the axial direction. Therefore, the support interval of the spool 104 is widened, and the reel 104 can be suppressed from rattling.

As shown in FIGS. 9 and 10, the towing mechanism 160 is a mechanism for the brake reel 104 to rotate in the direction in which the fishing line is repeatedly fed to cause the drag force to act on the reel 104. The drag mechanism 160 includes a drag knob 161 (an example of a second member), the spool shaft 115, a friction mechanism 162, an electroless nickel plating film 190 of a fluorine resin, and a drag sounding mechanism 185. The drag knob 161 is an operating member for adjusting the drag force by hand. The friction mechanism 162 that adjusts the drag force by pressing the knob 161 toward the reel 104 side by the drag knob 161 has, for example, four pieces of drag shims 162a to 162d (an example of a friction plate).

As shown in FIG. 10, the drag knob 161 has a knob portion 163 having a first knob member 166 and a second knob member 167 that relatively rotates the first knob member 166; and a first knob member 166 and a second knob The relative rotation of the member 167 causes a knob sounding mechanism (not shown) that emits sound.

In addition to the first knob member 166 and the second knob member 167, the knob portion 163 includes a coupling member 174 that is rotatably coupled to the first knob member 166 and the second knob member 167 in the axial direction.

The first knob member 166 is a metal member such as an aluminum alloy having a ring-shaped flange portion 166a and a cylindrical portion 166b having a smaller diameter than the flange portion 166a, such as an aluminum alloy. The first knob member 166 is provided on the spool shaft 115 so as not to be rotatable and freely movable in the axial direction. In the crotch The front end surface of the 166a, the sounding circular plate 169 constituting the knob sounding mechanism can be integrally rotated.

The sounding circular plate 169 is a member made of synthetic resin, and a plurality of sound emitting concave portions 169a are formed in the front surface thereof at intervals in the circumferential direction. A plurality of coupling projections 169b fitted to a plurality of coupling holes 166e formed in the flange portion 166a are formed behind the sounding circular plate 169. Thereby, the sounding circular plate 169 stops the first knob member 166.

In the inner peripheral portion of the cylindrical portion 166b, an oblong locking slit 166c that is non-rotatably engaged with the locking surface 115a of the spool shaft 115 is formed. The rear end surface of the cylindrical portion 166b is in contact with the drag pad 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 to 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 knob member 171 that is rotatable and freely movable in the axial direction, and a nut member that is screwed to the female screw portion 172a of the male screw portion 115b of the spool shaft 115. 172; and a spring member 173 which is disposed between the nut member 172 and the first knob member 166 in a compressed state and is constituted by a coil spring.

The knob body 171 includes a knob body 175 made of a synthetic resin and having a circular plate portion 175a and a cylindrical protruding portion 175b having a smaller diameter than the circular plate portion 175a, and a metal circular plate fixed to the front surface of the knob body 175. Cover portion 176; and gold fixed to the front of the cover portion 176 along the radial direction The operation knob 177 is a system.

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

The protruding portion 175b protrudes in a cylindrical shape toward the first knob member 166 so as to cover the crotch portion 166a of the first knob member 166. The crotch portion 166a of the first knob member 166 covered by the protruding portion 175b is prevented from coming off by the coupling member 174 attached to the inner peripheral surface of the protruding portion 175b. Thereby, the first knob member 166 and the second knob member 167 are rotatably coupled to each other and are not movable in the axial direction. A nut housing portion 175c that can freely move the nut member 172 in the axial direction and is rotatably housed is formed in the inner peripheral portion of the knob body 175.

The cover portion 176 is formed 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 portion 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 to gradually become thinner toward the center portion. The operation knob 177 is disposed along the diameter of the cover portion 176 and protrudes forward.

The joint member 174 is a member formed by bending a metal wire having elasticity. The connecting member 174 is a C-shaped spring member having four corner portions corresponding to a slightly square corner. The connecting member 174 is attached to the inner circumferential surface of the protruding portion 175b by the corner portion being locked to the annular groove formed on the inner circumferential surface of the protruding portion 175b. The connecting member 174 is made up of 3 between the corners The circular arc portions are in contact with the rear surface of the crotch portion 166a to prevent the crotch portion 166a from coming off.

The nut member 172 is, for example, a hex nut, and is screwed to a male screw portion 115b formed on the outer peripheral surface of the front end of the spool shaft 115, and the spring member 173 is compressed in response to the rotation of the knob body 175.

The knob sounding mechanism performs a drag operation, and when the second knob member 167 and the first knob member 166 are relatively rotated, they repeatedly collide with the sounding concave portion 169a to sound.

As shown in FIGS. 9 and 12, the drag lining 162a of the friction mechanism 162 is a metal disk member that is in contact with the first knob member 166 via the first support portion 156 and is not rotatable to the spool shaft 115. The drag shims 162b are metal disc members that are integrally rotatable to the reel 104. The drag washer 162c is a metal disc member that cannot rotate the spool shaft 115 similarly to the drag washer 162a. The tow pad 162d is a disk member such as felt or graphite that is freely rotatable to the reel 104 and the reel shaft 115. In the center portion of the drag shims 162a and 162c, an oblong locking slit 162e that is engaged with the locking surface 115a formed on the distal end side of the spool shaft 115 is formed. A plurality of (for example, eight) ear portions 162f protruding outward in the radial direction are formed on the outer circumferential surface of the drag shims 162b. The ear portion 162f is disposed on the inner circumferential surface of the tow storage tubular portion 152 at intervals in the circumferential direction, and is locked to a plurality of locking concave portions 152a formed along the axial direction. Thereby, the drag shims 162b are integrally rotatable to the reel 104.

The drag shims 162a to 162d are prevented from being detached by the first support portion 156 that supports the support cylinder portion 153. Therefore, when the detachment prevention spring 155 disposed in front of the support cylinder portion 153 is not removed, the shimming gasket is dragged. 162a~162d cannot be loaded or unloaded.

The drag sounding mechanism 185 is a mechanism that sounds when the spool shaft 115 rotates relative to the spool 104 by the operation of the drag. As shown in FIG. 12, the drag sounding mechanism 185 has a first sounding member 186 that is mounted on the back surface of the rear flange portion 104h of the spool 104, rotates integrally with the spool 104, and collides with the first sounding member 186. The second sounding member 187.

The first sounding member 186 has a cylindrical shape having a flange, and has a metal member having a plurality of arc-shaped sound receiving recesses 186a on the inner peripheral surface. A brand name 188 is disposed behind the first sounding member 186, and the first sounding member 186 is screwed to the back surface of the rear flange portion 104h together with the name plate 188.

The second sounding member 187 has two strike pins 187a that advance and retreat toward the sound concave portion 186a, and two spring members 187b that push the two strike pins 187a toward the sound concave portion 186a. The striking pin 187a is housed in the cylindrical housing member 189 that is non-rotatably engaged with the second locking surface 157d of the second support portion 157. The storage member 189 includes a thick cylindrical storage main body portion 189a having two storage grooves 189c for accommodating the striker pin 187a, and a screw fixed to the housing main portion 189a for blocking the storage groove 189c and the card The disc-shaped cover 189b is fitted to the second engagement surface 157d. The two housing grooves 189c of the housing main body portion 189a are opened to the outer peripheral surface of the housing main body portion 189a, and the interval between the two housing grooves 189c formed on the opening side is narrowed. A locking slit 189d that is engaged with the second locking surface 157d is formed on the inner circumferential surface of the cover 189b. The storage member 189 is attached A gasket 201 is disposed between the support wall portion 104e of the spool 104.

The first locking surface 157c that is engaged with the second support portion 157 is attached to the rear surface of the cover member 189b, and is, for example, a three-piece reel position adjusting washer 202 made of synthetic resin; and the restriction reel 104 is moved rearward. The two sheets limit the washers 203, 204. The locking slits 203a and 204a of the restricting washers 203 and 204 that are engaged with the locking surface 115a of the spool shaft 115 are formed on the inner peripheral portion, and are not rotatable to the spool shaft 215. The restriction washer 204 is a spacer having a step to hold the sealing member 205 with the restriction washer 203. The outer peripheral portion of the sealing member 205 is in contact with the inner peripheral surface of the first sounding member 186. The sealing member 205 is provided to prevent liquid from flowing from the rear of the spool 104 toward the inside of the spool 104 including the friction mechanism 162.

(Operation and action of the reel)

Before fishing, adjust the drag force according to the size and type of the fish. To adjust the drag force, the drag knob 161 is rotated. When the drag knob 161 is rotated in the clockwise direction, for example, the first knob member 166 is pressed toward the friction mechanism 162 via the spring member 173 by the nut member 172 screwed to the spool shaft 115. Thereby, the drag force becomes larger. At this time, by the relative rotation of the first knob member 166 and the second knob member 167, a click sound of a fast rhythm is generated.

When the casting is performed, the spinning frame 134 is reversed into a fishing line open posture. Thereby, the fishing line can be discharged from the reel 104. In this state, the index finger of the hand holding the fishing rod is hooked while hooking the fishing line. At that time, the fishing line will be released by the weight of the fishing group. In this state, when the handle will be When the 101 is rotated in the reeling direction of the fishline, the rotor 103 is rotated in the reeling direction by the rotor driving mechanism 105, and the spinning frame 134 is returned to the reeling position by the yarn reversing mechanism (not shown). The fishing line is wound to the reel 104 by a spinning frame 134.

In the case of jigging fishing, there is a need to adjust the drag force in response to the fish species caught during the take-up. Even in this case, since the electroless nickel plating film 190 of the fluorine resin is formed on the surface of the male screw portion 115b of the spool shaft 115, the sliding performance with the drag knob 161 is increased. Therefore, even if the drag force becomes large, the operation of the drag knob 161 can be performed with a light operating force.

(feature)

The foregoing embodiment can be expressed in the following manner.

(A) The towing mechanism 23 (or 160) of the fishing reel is a mechanism that can brake the rotation of the fishing line of the winding reel 12 (or 104) of the fishing reel in the reverse direction. The towing mechanism 23 (or 160) of the fishing reel is provided with a drive shaft 30 (or a reel shaft 115) having a first male screw portion 30f (or 115b); a star fishing valve 3 (or a drag knob 161) The friction mechanism 4 (or 162); and the electroless nickel plating film 90 (or 190) of the fluorine resin. The star fishing force valve 3 (or the drag knob 161) has a female screw portion 3d (or 172d) screwed to the first male screw portion 30f (or 115b). The friction mechanism 4 (or 162) brakes the reel 12 by rotating the star-shaped fishing valve 3 (or the drag knob 161) and the drive shaft 30 (or the reel shaft 115) relative to each other to change the frictional force ( Or 104) The fishing line repeatedly sends the rotating mechanism in the direction. The electroless nickel plating film 90 (or 190) of the fluorine-containing resin is formed at least in any one of the first male screw portion 30f (or the male screw portion 115b) and the female screw portion 3d (or 172a).

In the towing mechanism 23 (or 160), one of the first member, that is, the drive shaft 30 (or the spool shaft 115) and the second member, that is, the star-shaped fishing valve 3 (or the drag knob 161) is used as an operation member. By rotating it relative to the other member, the frictional force of the friction mechanism 4 (or 162) is changed, 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 fishing valve 3 (or the drag knob 161), An electroless nickel plating film 90 (or 190) having a fluorine-containing resin is formed. Therefore, the film thickness of the electroless nickel plating film 90 (or 190) of the fluorine-containing resin is uniform, and the sliding resistance between the first male screw portion 30f (or 115b) and the female screw portion 3d (or 172a) which are relatively rotated is changed. Small, the relative rotation of the first male screw portion 30f (or 115b) and the female screw portion 3d (or 172a) becomes smooth. Thereby, even if the drag force becomes large, the operation of the operating member can be performed with a light operating force. Further, the scratching sound in the operation of the star fishing force valve 3 (or the drag knob 161) becomes small, so that the operational feeling is improved.

(B) In the towing mechanism 23 (or 160) of the fishing reel, the fluororesin may also be obtained from polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyfluorinated diethylene (PVDF), poly Vinyl fluoride (PVF), perfluoroalkoxy resin (PFA), tetrafluoroethylene-hexafluoropropylene A group consisting of a copolymer (FEP), an ethylene-tetrafluoroethylene copolymer (ETFE), and an ethylene-chlorotrifluoroethylene copolymer (ECTFE) is selected. In this case, a resin having high slidability can be selected among the fluororesins.

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

(D) The towing mechanism 23 of the double-bearing reel may further include a reverse rotation preventing mechanism 66 that prohibits the rotation of the fishing line 30 in the reverse feeding direction. In this case, since the drive shaft 30 does not rotate in the reverse feed direction of the fishing line, the drag mechanism 62 can be configured to be integrally rotated on the drive shaft 30, thereby forming the drag mechanism 23 in a star-shaped drag configuration.

(E) In the towing mechanism 160 of the fishing reel, the fishing reel may be a spinning reel 200 that is rotatably wound around the reel shaft 115. The first member is a spool shaft 115 to which the spool 104 is rotatably mounted. The second member is a drag knob 161 that is screwed to the spool shaft 115. The friction mechanism 162 has at least one of the drag shims 162a to 162d disposed on the spool shaft 115 and pressed by the drag knob 161. In this case, the drag shims 162a to 162d are disposed around the spool shaft 115. The spinning reel can perform the operation of the drag knob 161 with a light operating force even if the drag force is large.

(F) In the towing mechanism 23 (or 160) of the fishing reel, the electroless nickel plating film 90 (or 190) of the fluorine resin may be formed in the first male screw portion 30f (or the male screw portion 115b). In this case, since the electroless nickel plating film 90 (or 190) of the fluorine resin is formed in the first male screw portion 30f (or the male screw portion 115b), the electroless nickel plating film is not electrolyzed in response to the adjustment position of the drag force. The contact position of the nickel plating film 90 (or 190) with the female screw portion 3d (or 172a) is changed. Further, therefore, it is possible to extend the life of the electroless nickel plating film 90 (or 190) of the fluorine-containing resin.

(G) In the towing mechanism 23 of the fishing reel, the electroless nickel plating film 90 of the fluorine resin may be a composite plating film in which fine particles of the fluororesin are dispersed and eutectoid. In this case, it is possible to suppress the increase in cost and form the electroless nickel plating film 90 of the fluorine-containing resin.

(H) In the towing mechanism 160 of the fishing reel, the electroless nickel plating film 190 of the fluorine-containing resin may be a nickel-phosphorus (Ni-P) porous body in which a fluororesin is composited by precipitation into a particulate form by heat treatment. Composite coating of the film. In this case, although the cost of forming the composite plating film is high, the hardness of the composite plating film is high.
