Description

[0001] DRAG MECHANISM FOR FISHING REEL FOR FISHING REEL [0002]

The present invention relates to a drag mechanism, and more particularly to a drag mechanism of a fishing reel in which a drag force can be adjusted by braking the rotation of the fishing line reel spool in the line releasing direction.

The fishing reel is provided with a drag mechanism for braking the rotation of the spool in the string releasing direction to adjust the drag force. The conventional drag mechanism has an operating member for adjusting the drag force, a screw member for screwing (screwing and screwing) the operating member, and a friction mechanism for changing the frictional force by turning the operating member. For example, in a double-bearing reel or a single-bearing reel in which a fishing line is wound by a rotating spool, an operating member is combined with 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 still spool by a rotor, an operating member is combined with a spool shaft as a screw member (see, for example, Patent Document 1).

In such a conventional drag mechanism, when the operating member rotates (rotates, circularly moves in the opposite direction in the forward direction), the engaging portion of the operating member moves in the axial direction of the screw member, And the drag force can be adjusted.

Japanese Patent Application Laid-Open No. 2009-148173

In the conventional drag mechanism, when the operating member is rotated, the turning operation of the operating member may become heavy. In particular, when a large drag force is set in a case where it is necessary to always adjust the drag force such as jigging, this phenomenon is likely to occur.

An object of the present invention is to make it possible to operate the operating member with a light operating force even if the drag force is large in the drag mechanism of the fishing reel.

The drag mechanism of the fishing reel is a mechanism for braking the rotation of the fishing reel in the line releasing direction of the line-winding spool. The drag mechanism of the fishing reel has 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 a female threaded portion that mates with the male threaded portion. The friction mechanism is a mechanism capable of braking the rotation of the spool in the line discharge direction by changing the frictional force by relatively rotating the first member and the second member. The fluororesin-containing electroless nickel plating film is formed on at least one of the male thread portion and the female thread portion.

In this drag mechanism, one of the first member and the second member is rotated relative to the other member as an operating member, whereby the frictional force of the friction mechanism changes, and the drag force can be adjusted. A fluorine resin-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. As a result, the film thickness of the electroless nickel plated film containing fluororesin becomes uniform, and the sliding resistance (slidable contact and sliding) between the relatively rotating male threaded portion and the female threaded portion becomes small, The relative rotation between the female screw portion becomes smooth. Thus, even if the drag force is increased, the operation member can be operated with a light operation force. In addition, the squeaking sound during operation of the operating member is reduced, and the operation feeling improves.

In the drag mechanism of a fishing reel, the fluororesin may be at least one selected from the group consisting of polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride It is preferable to use a group consisting of an alkoxy fluorine resin (PFA), an ethylene fluoride · propylene hexafluoride copolymer (FEP), an ethylene · tetrafluoroethylene copolymer (ETFE), and an ethylene · chlorotrifluoroethylene copolymer (ECTFE) It may be selected. In this case, among fluororesins, those having particularly high sliding properties can be selected.

In the drag mechanism of the fishing reel, the fishing reel may be a double-bearing reel or a single-bearing reel in which the spool rotates by the rotation of the handle. The first member is a drive shaft that rotates by the rotation of the handle. The second member is an operating member that mates with the drive shaft. The friction mechanism has at least one friction plate which is disposed on the drive shaft and which is pressed (depressed and depressed) by the operating 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, even if the drag force is large, the operation member can be operated with a light operation force.

The drag mechanism of the fishing reel may further include a reverse rotation preventing mechanism for prohibiting the rotation of the drive shaft in the line release direction. In this case, since the drive shaft does not rotate in the line discharge direction, a star drag type drag mechanism can be constituted by providing at least the friction plate integrally rotatable with the drive shaft.

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

In the drag mechanism of the fishing reel, the electroless nickel plated film containing fluorine resin may be formed on the male threaded portion. In this case, since the electroless nickel plating film containing fluorine resin is formed on the male thread portion of the first member, the contact position between the fluorine resin-containing electroless nickel plating film and the female threaded portion changes depending on the adjustment position of the drag force. For this reason, the life span of the electroless nickel plating film containing fluororesin can be increased.

In the drag mechanism of the fishing reel, the electroless nickel plating film containing fluororesin may be a composite plating film obtained by dispersing fine particles of fluororesin in an eutectoid. In this case, an increase in cost can be suppressed to form a fluororesin-containing electroless nickel plating film.

In the drag mechanism of the fishing reel, the fluorine resin-containing electroless nickel plating film is formed by combining a porous film of nickel-phosphorus (Ni-P) precipitated in particulate form with a fluororesin by heat treatment It is also possible to use a composite plating film. In this case, although the formation cost of 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 relatively rotating male screw portion and the female screw portion is reduced, and the relative rotation between the male screw portion and the female screw portion is smooth. Thus, even if the drag force is increased, the operation member can be operated with a light operation force.

The casting control mechanism 24 adjusts the resistance force of the spool 12 when the spool 12 rotates.

The spool 12 is fixed to the spool shaft 20 passing through the center thereof. The spool shaft 20 is rotatably supported on the reel body 1 by a bearing.

The clutch lever 17 is disposed rearwardly of the spool 12 at the rear portion between the first side plate 8 and the second side plate 9 as shown in Fig. The clutch lever 17 slides in the vertical direction between the first side plate 8 and the second side plate 9. A shaft 17a for engagement and engagement is integrally formed through the second side plate 9 on the handle mounting side of the clutch lever 17. [ The engaging shaft 17a is engaged with the clutch control mechanism 22.

The level wind mechanism 18 is disposed between the first side plate 8 and the second side plate 9 at the front side of the spool 12 as shown in Fig. A traverse cam shaft 46 formed with a helical groove 46a intersecting with the traverse cam shaft 46 and a fishing line guide portion 47 reciprocating in the axial direction of the spool by the traverse cam shaft 46. [

The rotation transmission mechanism 19 includes a drive shaft 30 (an example of the first member), a drive gear 31 fixed to the drive shaft 30, and a cylindrical pinion A gear member 48 which is rotatably mounted on the right end of the traverse cam shaft 46 as shown in Fig. 3 and a pinion gear 32 which is non-rotatably supported at the base end of the drive shaft 30 And a gear member 49 mounted thereon.

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 is provided with a shaft portion 30a which is rotatably supported from the base end side toward the tip end side, a first engagement portion The third engagement portion 30e, the first male screw portion 30f, the second male screw portion 30g, and the second male screw portion 30g, And a fourth locking portion 30h are formed. A bearing 28 is mounted on the shaft 30a. The first stopper portion 30b is formed by two chamfered chamfer portions larger in diameter than the shank portion 30a and parallel to each other. The rim portion 30c is larger than the first engagement portion 30b. The second locking portion 30d is composed of two chamfer portions smaller in diameter than the rim portion 30c and parallel to each other. The third locking portion 30e is formed by a pair of chamfered portions smaller in diameter than the second locking portion 30d and parallel to each other. The first male screw portion 30f is formed on the outer circumferential surface of the third engaging portion 30e excluding the third engaging portion 30e. The second male screw portion 30g is formed at the tip end portion of the drive shaft 30 with a smaller diameter than the first male screw portion 30f. The fourth engagement portion 30h is formed on the outer peripheral surface of the drive shaft 30 on which the second male screw portion 30g is formed. The handle 2 is not rotatably mounted on the fourth engagement portion 30h and the handle 2 is fixed to the drive shaft 30 by the nut 43 inserted into the second male screw portion 30g.

On the surface of the first male screw portion 30f, as shown schematically in FIG. 6, a fluorine resin-containing electroless nickel plating film 90 is formed. Incidentally, the shape of the screw is omitted in Fig. The fluororesin-containing electroless nickel plating film 90 is a composite plating film formed by dispersing fine particles of a fluororesin substantially uniformly in a nickel plating solution. The fluororesin used in the fluororesin-containing electroless nickel plating film 90 may be at least one selected from the group consisting of polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF) , A group consisting of a perfluoroalkoxy fluoropolymer (PFA), an ethylene fluoride · propylene hexafluoride copolymer (FEP), an ethylene · tetrafluoroethylene copolymer (ETFE), and an ethylene · chlorotrifluoroethylene copolymer (ECTFE) . Preferably, the fluororesin is polytetrafluoroethylene (PTFE). Incidentally, in Fig. 6, a fluororesin is schematically shown by dots. The film thickness of the electroless nickel plating film 90 containing fluorine resin is, for example, in the range of 2 탆 to 20 탆, and preferably in the range of 5 탆 to 15 탆. The amount of vacancy of the fluororesin is, for example, from 1.5 to 10 percent by weight of the entire plating solution.

The drive shaft 30 is rotatably mounted on the reel unit 1 and includes a first one way clutch 86 of a roller type and a second one way clutch of a detent type, (Reverse rotation) in the line discharging direction by the way clutch 87 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 in a middle portion of the drive shaft 30 and is mounted in a gap between the second side cover 7 of the reel unit 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 86c disposed between the outer ring 86a and the inner ring 86b.

The second one-way clutch 87 includes a ratchet wheel 61 and a ratchet pawl (not shown) pivotally mounted on the outer side surface of the second side plate 9 of the reel unit 1 67 (see Fig. 5). The ratchet wheel 61 is non-rotatably mounted to the second engagement portion 30d between the drive gear 31 and the gear member 49. [ The ratchet wheel 61 is disposed in contact with the rim portion 30c, and the movement toward the base end side is regulated by the rim portion 30c. At the outer periphery of the ratchet wheel 61, ratchet teeth 61a protruding in a substantially parallelogram shape are arranged at intervals in the circumferential direction. The ratchet pawl 67 mounted on the reel main body 1 so as to be pivotable is engaged with the ratchet teeth 61a so that rotation of the drive shaft 30 in the row releasing direction is prohibited. The second one-way clutch 87 functions as a friction plate of the drag mechanism 23.

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

3, the pinion gear 32 is a normal member extending inward from the outer side of the second side plate 9 and passing through the spool shaft 20 at the center. The pinion gear 32 is mounted on the spool shaft 20 so as to be movable in the axial direction. An engaging groove 32a is formed at the left end of the pinion gear 32 in FIG. 3 so as to engage with the engaging pin 20b which penetrates the spool shaft 20 in the radial direction. The clutch mechanism 21 is constituted by the engagement groove 32a and the engagement pin 20b mounted on the spool shaft 20. A conical portion 32b is formed in the middle portion of the pinion gear 32 and a gear portion 32c is formed in the right end portion of the pinion gear 32 to engage with the driving gear 31. [ The clutch yoke 22a of the clutch control mechanism 22 is engaged with the constricted portion 32b.

The gear member 49 is non-rotatably mounted on the first engagement portion 30b formed at the proximal end of the drive shaft 30 and is brought into contact with the rim portion 30c from the proximal end side in a contact manner . The gear member 48 mounted on the traverse cam shaft 46 meshes with the gear member 49 mounted on the drive shaft 30. [ With this 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 line winding direction.

The drag mechanism 23 is a mechanism for interlocking the drive shaft 30 and the drive gear 31 to a predetermined drag force to brak the rotation of the spool 12 in the line discharge direction. The drag force is adjusted by the fastening state of the star drag (3). 4 and 5, the drag mechanism 23 includes the star drag 3, the drive shaft 30, the friction mechanism 4, and the above- And a nickel plating film 90 (see FIG. 6). Further, the drag mechanism 23 is provided with a phonetic device 65 and the above-described reversal preventive mechanism 66.

3, the star drag 3 includes a body portion 3b having a plurality of operating portions 3a disposed radially and a body portion 3b having a body portion 3b integrally rotatable with the body portion 3b, And a nut member 3c disposed so as to be movable in a direction. The nut member 3c has a female screw portion 3d that mates with the first male screw portion 30f. The star drag 3 is an operating member for adjusting a predetermined drag force by pressing the friction mechanism 4 mounted on the drive shaft 30 at the base end side thereof. Four dish springs 88 are mounted between the star drag 3 and the first one-way clutch 86. The plate spring 88 is provided to smoothly transmit the tightening force of the star drag 3 to the drag plate 62 to be described later. The plate spring 88 is disposed between the nut member 3c of the star drag 3 and the inner ring 86b of the first one-way clutch 86.

The star drag 3 adjusts the tightening state so that the drive shaft 30 is rotated by the inner spring 86b of the first one-way clutch 86 mounted on the second side cover 7 against the plate spring 88 (See Fig. 3). That is, by the rotation of the star drag 3, the pressing force of the plate spring 88 is adjusted. Thus, the drag force can be finely adjusted by the star drag 3.

The friction mechanism 4 has a drag plate 62 (an example of a friction plate) and a ratchet wheel 61 (an example of a friction plate) which are integrally rotatably engaged with the drive shaft 30. The drag plate 62 is a disc member that contacts the drive gear 31 (an example of the second friction plate) from the handle 2 side through a first drag washer 63a. The drag plate 62 is mounted to the third lock portion 30e so as to be rotatable integrally with the drive shaft 30. [ The drag plate 62 holds the drive gear 31 with the ratchet wheel 61. Further, the drag plate 62 is non-rotatably connected to and in contact with the inner ring 86b of the first one-way clutch 86. As a result, the inner wheel 86b of the first one-way clutch 86 can rotate integrally with the drive shaft 30 and transmits the pushing force of the star drag 3 to the drag plate 62. An engaging hole 62a engaging with the third engaging portion 30e of the drive shaft 30 in a rotatable manner is integrally formed at the center of the drag plate 62 so as to be rotatable integrally with the inner ring 86b . The driving gear 31 contacts the ratchet wheel 61 through the second drag washer 63b.

The second drag washer 63b 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 circumferential 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 driving gear 31 side. The engaging pin 64a engages with one of the pair of engaging holes 31a and 31b formed through the side surface of the driving gear 31. [ As a result, the ring member 64 rotates in conjunction with the driving gear 31. [ The thickness of the ring member 64 is thinner than the thickness of the second drag washer 63b. Therefore, even if the drag plate 62 is pressed by the star drag 3 and the drive gear 31 is held by the drag plate 62 and the ratchet wheel 61, the pushing force acts on the ring member 64 And is rotatable.

The sounding mechanism 65 includes a striking pin 70 mounted on the gear member 49 movably in the direction of the drive shaft and a plurality of circumferentially spaced apart side surfaces on the side opposite to the handle side of the ring member 64 A sound output recess 71 and a coil spring 72 for urging the striking pin 70 toward the ring member 64. The striking pin (70) has a head portion which is engaged with the concave depression (71) at the tip end. The striking pin 70 and the coil spring 72 are accommodated in a cylindrical portion 49a formed to protrude from the handle side of the gear member 49. The cylindrical portion 49a is large enough to be inserted into the through hole 61b formed in the vicinity of the center hole of the ratchet wheel 61 and exposed to the ring member 64 side. The plurality of concave depressions 71 are formed on the side surface of the ring member 64 that is opposed to the striking fins 70 at intervals in the circumferential direction. When the drive shaft 30 and the drive gear 31 rotate relative to each other due to the operation of the drag, the ratchet striking pin 70 can not rotate relative to the drive shaft 30, And collides with the concave depressions 71 formed in the ring member 64 rotating together with the sound.

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

When winding the fishing line, turn the handle 2 in the line-winding direction. The rotation of the handle 2 is transmitted from the drive shaft 30 to the drive gear 31 and the pinion gear 32 interlocked with the drive shaft 30 via the drag mechanism 23. [ The rotation of the pinion gear 32 is transmitted to the spool shaft 20 which is engaged with the pinion gear 32 by the clutch mechanism 21 and the spool 12 is rotated to wind the fishing line. The rotation of the drive shaft 30 is transmitted to the traverse cam shaft 46 through the gear member 49 and the gear member 48. The rotation of the traverse cam shaft 46 causes the fishing line guide portion 47 to rotate 20). By this reciprocating motion, the fishing line is wound on the spool 12 approximately uniformly.

On the other hand, when releasing the fishing line, the clutch lever 17 is operated to release the clutch mechanism 21 by the clutch control mechanism 22. Even if the spool 12 rotates due to the release of the fishing line, the rotation is transmitted to the rotation transmitting mechanism 19 and the driving shaft 30, It does not.

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

Tension is applied to the fishing line when fishing. As a result, a torque is applied to the spool 12 to rotate in the spiral direction. The drive gear 31 is pressed against the first drag washer 63a by the plate spring 88 compressed by the tightening of the star drag 3 while the drag force acting on the spool 12 is smaller than the set drag force, And the drive gear 31 and the drive shaft 30 are not rotatable relative to each other. The spool 12 interlocked with the drive gear 31 does not rotate in the lane departure direction because the drive shaft 30 is stopped by the reversing prevention mechanism 66 so as not to rotate in the lane departure direction. 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 The torque that can be transmitted between the ratchet wheel 61 and the drag plate 62 and the drive gear 31 can be increased by the pushing force of the small plate spring 88. [

The second drag washer 63b and the first drag washer 63a between the ratchet wheel 61 and the drag plate 62 and the drive gear 31 are engaged with the first drag washer 63a when the tension applied to the fishing line becomes high and the torque applied to the spool 12 increases. A slip is generated in the pressure contact portion. Thus, even if the driving shaft 30 is stopped, the driving gear 31 rotates in the line discharging direction while receiving the resistance of the dynamic friction, and the spool 12 also rotates in the line discharging direction. When the torque acting on the spool 12 exceeds a predetermined value, in other words, when an excessively large tension is applied to the fishing line, the drag mechanism 23 is operated to rotate the spool 12 in the line- , Thereby protecting the fishing line from excessive tension.

When the fish is pulled up, when the spool 12 rotates in the line releasing direction as described above, the sounding mechanism 65 of the drag mechanism 23 generates sound. When the drive shaft 31 and the drive gear 31 rotate relative to each other, a concave portion 71 formed in the ring member 64 rotating in conjunction with the drive gear 31, The striking pin 70 rotating in conjunction with the member 49 interferes to generate click noise. This click sound is generated by intermittent abutment of the head portion of the impact pin 70 pressed by the coil spring 72 against the concave portion 71 arranged at equal intervals (equidistantly spaced), so that the rhythmical ) One note. The ring member 64 is made thinner than the second drag washer 63b and the ring member 64 is made thinner than the second drag washer 63b by the clearance between the locking pin 64a and the locking hole 31a, With respect to the axial direction as well. As described above, since the ring member 64 is not pressed by the other member, the generated sound sounds well, and the volume is also large.

In addition, when jigging is performed, the star drag (3) is turned frequently to adjust the drag force. At this time, the nut member 3c is rotated with respect to the first male screw portion 30f, and the nut member 3c is moved in the axial direction of the drive shaft 30. For example, when the star drag 3 is rotated in the clockwise direction in Fig. 2, the nut member 3c moves in the direction approaching the first one-way clutch 86 and presses the plate spring 88, The power increases. 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 electroless nickel plating film 90 containing fluorine resin is formed on the surface of the first male threaded portion 30f to reduce the sliding resistance of the nut member 3c and smooth the nut member 3c Rotate. As a result, even if the drag force is increased, the star drag 3 can be operated with a light operation force. Moreover, the creaking sound during the operation of the star drag 3 is reduced, and the operation filling is improved.

And has a portion 104i. A connecting portion 130 of the rotor 103 is disposed on the inner side of the cylindrical portion 104i.

A metal spool ring 120 is mounted on the outer peripheral surface of the front flange portion 104c to smoothly discharge the fishing line from the winding body portion 4a. The spool ring 120 has an inclined surface 120a that widens toward the front end. The spool ring 120 is fixed to the entire flange portion 104c by the ring fixing member 119. [ The ring fixing member 119 is engaged with a normal female threaded portion 104j projecting forward from the front flange portion 104c.

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

The inner ring of the bearing 158b is mounted on the small diameter portion 157a. The outer ring of the bearing 158b is mounted on the shaft supporting portion 104f of the bobbin trunk 104a. In the large-diameter portion 157b, a first restricting surface 157c composed of mutually parallel surfaces and a second restoring surface 157d orthogonal to the first restricting surface 157c are formed. The second support portion 157 is fixed to the spool shaft 115 in a non-rotatable manner by a detent screw 159 arranged to pass through the first engagement surface 157c. The detent screw 159 is a hollow set screw with a slit 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 constitution, since 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 arranged in the support cylinder portion 153, The spacing between the two bearings 158a and 158b in the axial direction can be widened as compared with the conventional structure in which two bearings are arranged side by side in the shaft portion 104f. Therefore, the support interval of the spool 104 is widened, and the rattling of the spool 104 can be suppressed.

9 and 10, the drag mechanism 160 is a mechanism for applying a drag force to the spool 104 by braking the rotation of the spool 104 in the string releasing direction. The drag mechanism 160 includes a drag handle 161 (an example of the second member), the spool shaft 115, the friction mechanism 162, the electroless nickel plating film 190 containing fluorine resin, And a dragging sounding mechanism 185 are provided.

The first pull member 166 is a metallic member such as an aluminum alloy with a frame having a ring-like rim portion 166a and a cylindrical portion 166b having a smaller diameter than the rim portion 166a. The first pull member 166 is rotatably and axially movably provided on the spool shaft 115. On the front end face of the rim portion 166a, a sound outputting plate 169 constituting a knob sounding mechanism is integrally rotatably provided.

The sound output disk 169 is made of a synthetic resin, and on the front surface thereof, a plurality of concave depressions 169a are formed at intervals in the circumferential direction. A plurality of connection protrusions 169b are formed on the rear surface of the cutout circular plate 169 to fit into a plurality of connection holes 166e formed in the rim portion 166a. As a result, the original discharge plate 169 is stopped to rotate with respect to the first handle member 166.

An elongated retaining slot 166c engaging with the restricting surface 115a of the spool shaft 115 is formed at an inner peripheral portion of the cylindrical portion 166b. The rear end surface of the cylindrical portion 166b abuts on the drag seat 162a of the friction mechanism 162 through the first support portion 156. [

The second pull member 167 is arranged to face the first pull member 166 and is provided so as to be able to rotate relative to the first pull member 166. [ The second handle member 167 is a member that normally projects toward the first handle member 166 so as to cover the rim portion 166a while being engaged with the spool shaft 115. [ The second handle member 167 includes a handle 171 and a female screw portion 173 which is mounted on the handle 171 so as to be nonrotatable and axially movable and which is engaged with the male screw portion 115b of the spool shaft 115, And a spring member 173 composed of a coil spring disposed in a compressed state between the nut member 172 and the first pull member 166.

Four bolt members 180a to 180d are inserted from the rear surface side of the disk portion 175a of the knob body 175 and inserted into the operation knob 177 through the cover portion 176 . Thus, the cover portion 176 and the operation knob 177 are fixed to the knob body 175.

The projection 175b normally projects toward the first pull member 166 so as to cover the rim portion 166a of the first pull member 166. [ The rim portion 166a of the first pull member 166 covered with the projecting portion 175b is prevented from falling out by the connecting member 174 mounted on the inner peripheral surface of the projecting portion 175b. Thereby, the first pull member 166 and the second pull member 167 are connected to each other so as to be relatively rotatable and axially non-movably. A nut accommodating portion 175c is formed in the inner peripheral portion of the knob body 175 so that the nut member 172 is axially movably and integrally rotatably housed.

The cover portion 176 is formed so as to cover the entire surface of the disc portion 175a of the knob body 175 and a part of the outer peripheral surface. As a result, the synthetic resin handle body 175 constituting the mechanical part of the drag handle 161 is covered in the spool 104 and is not exposed to the outside. The front surface of the cover portion 176 is cut so that its thickness gradually decreases toward the central portion. The operation knob 177 is disposed along the diameter of the cover portion 176 and projects forward.

The connecting 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 an approximately square angle. The connecting member 174 is mounted on the inner circumferential surface of the projecting portion 175b by engaging each part in an annular groove formed in the inner circumferential surface of the projecting portion 175b. The connecting member 174 prevents the rim portion 166a from slipping out by the three arc portions between the leg portions contacting the rear surface of the rim portion 166a.

The nut member 172 is, for example, a hexagon nut and is engaged with the male screw portion 115b formed on the outer peripheral surface of the distal end of the spool shaft 115 to compress 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 dragging operation, the knob sounding mechanism repeats the collision with the concave concave portion 169a.

9 and 12, the drag lever 162a of the friction mechanism 162 is in contact with the first knob member 166 through the first support portion 156 and is also engaged with the spool shaft 115 Is a non-rotatable metal disc member. The drag bowl 162b is a disk member made of metal capable of rotating integrally with the spool 104. [ Like the drag bowl 162a, the drag bowl 162c is a disk member made of metal which is not rotatable with respect to the spool shaft 115. [ The drag bowl 162d is a disc member made of felt or graphite which is rotatable with respect to the spool 104 and the spool shaft 115, for example. At the center of the drag locks 162a and 162c is formed a locking slot 162e having a circular shape engaging with the locking surface 115a formed at the tip end side of the spool shaft 115. [ On the outer peripheral surface of the drag bowl 162b, a plurality of (for example, eight) ear portions 162f protruding outward in the radial direction are formed. These ear portions 162f are disposed on the inner circumferential surface of the drag receiving cylinder 152 at intervals in the circumferential direction and engage with a plurality of engaging concave portions 152a formed along the axial direction. Thus, the drag bowl 162b can rotate integrally with the spool 104. [

The drag holders 162a to 162d are prevented from being dislodged by the first support portion 156 that supports the support barrel 153. [ Therefore, the drag locks 162a-162d can not be attached or detached unless the lock-off preventing spring 155 disposed at the front of the support cylinder 153 is removed.

The dragging sound generating mechanism 185 is a mechanism that sounds when the spool shaft 115 and the spool 104 rotate relative to each other by the drag operation. 12, the drag sounding mechanism 185 includes a first sound emitting member 186 mounted on the back surface of the rear flange portion 104h of the spool 104 and rotating integrally with the spool 104, And repeats the impact with respect to the first sound emitting member 186 and has the second sound emitting member 187.

The first sound emitting member 186 is a metal member having a cylindrical shape with a stepped shape and having a plurality of arc-shaped concave concave portions 186a formed on its inner circumferential surface. A name plate 188 is disposed on the rear face of the first sound emitting member 186 and the first sound emitting member 186 is screwed to the back face of the rear flange portion 104h together with the name plate 188. [

The second sound emitting member 187 includes two striking fins 187a for moving back and forth toward the striking recess 186a and two spring fingers 187a for urging the striking fins 187a toward the striking recess 186a. Lt; / RTI &gt; The striking pin 187a is housed in a common receiving member 189 that is non-rotatably engaged with the second guiding surface 157d of the second supporting portion 157. [ The receiving member 189 has a thick cylindrical main body 189a having two receiving grooves 189c for retractably receiving the striking pin 187a, And has a disk-shaped cover 189b engaging with the second restricting surface 157d, as well as closing the receiving groove 189c with a screw. The two receiving grooves 189c of the receiving main body portion 189a are formed in the outer peripheral surface of the receiving main body portion 189a and are formed such that the interval between the two receiving grooves 189c on the opening side is narrowed. An engagement slot 189d engaging with the second engagement surface 157d is formed on the inner peripheral surface of the cover 189b. A washer 201 is disposed between the housing member 189 and the support wall portion 104e of the spool 104. [

The rear surface of the cover 189b is provided with three spool position adjustment washers 202 made of, for example, synthetic resin, which engage with the first rest surface 157c of the second support portion 157, Two regulating washers 203 and 204 for restricting the rearward movement are mounted. The regulating washers 203 and 204 are formed with locking slots 203a and 204a engaged with the locking surfaces 115a of the spool shaft 115 and are not rotatable with respect to the spool shaft 215. [ The regulating washer 204 is a stepped washer and seals the regulating washer 203 and the seal member 205. [ The outer peripheral portion of the seal member 205 is in contact with the inner peripheral surface of the first sound emitting member 186. The seal member 205 is provided to prevent the inflow of liquid from the rear surface of the spool 104 into the spool 104 including the friction mechanism 162. [

[Reel operation and operation]

Adjust the drag force to match the size and type of fish before fishing. To adjust the drag force, turn the drag knob (161). The first handle member 166 is moved toward the friction mechanism 162 through the spring member 173 by the nut member 172 engaging with the spool shaft 115 when the drag handle 161 is turned clockwise, And pressed. This increases the drag force. At this time, a clear and light click sound is generated by the relative rotation of the first pull member 166 and the second pull member 167. [

At the time of casting, the bail arm 134 is reversed to the line-releasing posture. Thus, the fishing line can be discharged from the spool 104. In this state, the fishing rod is cast while hooking the fishing line with the forefinger of the hand holding the fishing rod. The fishing line is then vigorously ejected by the weight of the preparation. 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 and the bail arm 134 is rotated in the bail inversion mechanism And the fishing line is wound on the spool 104 by the bail arm 134. As a result,

When jigging is performed, there may be a situation where the drag force must be adjusted depending on the fish that is caught at the time of winding the line. Even in this case, since the electroless nickel plating film 190 containing 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 enhanced. Therefore, even if the drag force is increased, the drag handle 161 can be operated with a light operation force.

<Features>

The above embodiment can be expressed as follows.

(A) The drag mechanism 23 (or 160) of the fishing reel is a mechanism for braking the rotation of the spool 12 (or 104) for fishing line reeling in the fishing line reeling direction. The drag mechanism 23 (or 160) of the fishing reel has the drive shaft 30 (or the spool shaft 115) having the first male thread portion 30f (or 115b) and the star drag 3 A handle 161), a friction mechanism 4 (or 162), and a fluororesin-containing electroless nickel plating film 90 (or 190). The star drag 3 (or the drag handle 161) has a female screw portion 3d (or 172a) that mates with 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 the drag handle 161) and the drive shaft 30 (or the spool shaft 115) Is a mechanism capable of braking the rotation of the spool 12 (or 104) in the line releasing direction. The fluororesin-containing electroless nickel plating film 90 (or 190) is formed on at least one of the first male threaded portion 30f (or the male threaded portion 115b) and the female threaded portion 3d (or 172a).

In this 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 handle 161) as the second member is operated The frictional force of the friction mechanism 4 (or 162) is changed by rotating the member relative to the other member so that the drag force can be adjusted. Of the female screw portion 3d (or 172a) of the first male screw portion 30f (or 115b) and the star drag 3 (or drag handle 161) of the drive shaft 30 (or the spool shaft 115) A fluororesin-containing electroless nickel plating film 90 (or 190) is formed on at least one of them. Therefore, the film thickness of the electroless nickel plating film 90 (or 190) containing fluororesin becomes uniform, and the first male threaded portion 30f (or 115b) and the female threaded portion 3d (or 172a) And the relative rotation between the first male screw portion 30f (or 115b) and the female screw portion 3d (or 172a) is smooth. Thus, even if the drag force is increased, the operation member can be operated with a light operation force. In addition, the creaking sound during the operation of the star drag 3 (or the drag handle 161) is reduced, and the operation filling is improved.

(B) In the drag mechanism 23 (or 160) of the fishing reel, the fluororesin may be at least one selected from the group consisting of polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF) (PTFE), fluorinated ethylene · hexafluoropropylene copolymer (FEP), ethylene · tetrafluoroethylene copolymer (ETFE), and ethylene · chlorotrifluoroethylene copolymer (ECTFE). In this case, among fluororesins, those having particularly high sliding properties can be selected.

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

(D) Further, the drag mechanism 23 of the double-bearing reel may further include an anti-reverse mechanism 66 for inhibiting the rotation of the drive shaft 30 in the row ejection direction. In this case, since the drive shaft 30 does not rotate in the line releasing direction, the drag plate 62 can be integrally rotatable with at least the drive shaft 30 to constitute the star drag type drag mechanism 23 .

(E) In the drag mechanism 160 of the fishing reel, the fishing reel is a spinning reel 200 rotatably wound 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 handle 161 that mates with the spool shaft 115. The friction mechanism 162 includes at least one drag pad 162a to 162d disposed on the spool shaft 115 and pressed by the drag handle 161. [ In this case, in the spinning reel in which the drag locks 162a to 162d are arranged around the spool shaft 115, even if the drag force is large, the drag knob 161 can be operated with a light operation force.

(Or F) In the drag mechanism 23 (or 160) of the fishing reel, the fluororesin-containing electroless nickel plating film 90 (or 190) has the first male thread 30f (or the male thread 115b) As shown in Fig. In this case, since the fluorine resin-containing electroless nickel plating film 90 (or 190) is formed on the first male screw portion 30f (or the male screw portion 115b), the fluororesin- The contact position between the electroless nickel plating film 90 (or 190) and the female threaded portion 3d (or 172a) changes. For this reason, it is possible to increase the life span of the electroless nickel plating film 90 (or 190) containing fluororesin.

(G) In the drag mechanism 23 of the fishing reel, the electroless nickel plated film 90 containing fluororesin may be a composite plated film obtained by dispersing and depositing fine particles of fluororesin. In this case, the increase in cost can be suppressed and the electroless nickel plating film 90 containing fluorine resin can be formed.

(H) In the drag mechanism 160 of the fishing reel, the fluororesin-containing electroless nickel plating film 190 is formed by heat-treating a porous film of nickel-phosphorus (Ni-P) It is also possible to use a complex plated coating film. In this case, although the formation cost of the composite plating film is high, the hardness of the composite plating film is high.

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

(b) In the first and second embodiments, the electroless nickel plating film containing fluorine resin is formed on the drive shaft or the spool shaft as the first member, but the present invention is not limited to this. For example, a fluorine resin-containing electroless nickel plating film may be provided on the female screw portion provided on the first member, the star drag or the drag handle.

(c) A nickel-plated film or a nickel-boron plated film in which a fluororesin is dispersed in place may be used in place of the nickel-plated film obtained by dispersing the fluororesin of the first and second embodiments. However, in this case, the cost of forming the composite plating film becomes higher.

(d) In the above embodiment, polytetrafluoroethylene (PTFE) is exemplified as the fluororesin, but the present invention is not limited thereto. The fluororesin may be at least one selected from the group consisting of polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), perfluoroalkoxy fluoropolymer (PFA) Any of those selected from the group consisting of propylene hexafluoropropylene copolymer (FEP), ethylene · tetrafluoroethylene copolymer (ETFE), and ethylene · chlorotrifluoroethylene copolymer (ECTFE) may be used.

(e) In the first embodiment and the second embodiment, the first male threaded portion 30f (or the male threaded portion 115b) of the drive shaft 30 (or the spool shaft 115) Containing electroless nickel plating film 90 (or 190), but the present invention is not limited thereto. The electroless nickel plating film containing fluorine resin may be formed on the female threaded portion 3d (or 172a) of the nut member 3c (or 172) as the second member. An electroless nickel plating film containing fluorine resin may be formed on both of the first male screw portion 30f (or the male screw portion 115b) and the female screw portion 3d (or 172a). Further, a fluororesin-containing electroless nickel plating film may be formed on the whole of the drive shaft 30 (or the spool shaft 115).
