Description

  The present invention relates to a braking device, and more particularly to a spinning reel rotor braking device that brakes the rotation of a rotor that is rotatably mounted on a reel body of a spinning reel in the line-feeding direction.

  In general, when performing fishing for a rod, a lever brake type spinning reel having a rotor braking mechanism in which rotation (reverse rotation) of a rotor in a line-feeding direction is braked by a braking operation member (an example of a braking operation member) is often used. Lever brake type spinning reels are used to loosen the braking force to the extent that it does not prevent the fish from feeding.

  In this type of conventional lever brake type spinning reel, a spinning reel capable of switching the reverse rotation of the rotor between a predetermined braking state and a braking release state is known (see Patent Document 1). The conventional spinning reel has a braking member that rotates in conjunction with the reverse rotation of the rotor, a braking lever that can adjust the braking force by contacting the braking member at its tip, and an auxiliary lever that is arranged side by side with the braking lever. is doing. The brake lever is supported on the reel body so as to be swingable in a direction in which the rod comes in contact with and away from the fishing rod mounting portion. When the brake lever is operated in a direction approaching the fishing rod, the tip presses the braking member, and the braking force gradually increases.

The auxiliary lever is supported by the reel body so as to be swingable about the same axis as the brake lever. The auxiliary lever includes a first predetermined braking portion that switches between a first predetermined braking state and a brake releasing state, and a second predetermined braking that switches between a second predetermined braking state and a braking releasing state that have greater braking force than the first predetermined braking state. Connected to the part. The first predetermined braking portion includes a lever member that swings about an axis parallel to the spool axis in conjunction with the auxiliary lever. A first predetermined braking state is obtained by pressing a part of the lever member against the braking member. The second predetermined braking portion has a structure similar to a drag mechanism having a plurality of disk members arranged side by side with the braking member. A second predetermined braking state is obtained by prohibiting one rotation of the disk member. A switching lever for switching one of the disk members to a rotation prohibited / rotation permitted state is swingably mounted on the reel body. When the auxiliary lever is swung in the direction approaching the saddle mounting portion, the switching lever is swung to the rotation permission position side by the lever member.

  In the conventional spinning reel, since the first predetermined braking state by the first predetermined braking portion only presses the lever member against the braking member, the area of the friction portion is limited. For this reason, it is difficult to obtain a strong braking force, and the obtained braking force may not be stabilized. Therefore, in order to stably obtain a stronger braking force, a strong second predetermined braking state is obtained by providing a second predetermined braking portion having a disk member arranged side by side on the braking member. However, since the structure of the second predetermined braking portion is similar to a drag mechanism having a plurality of disk members, the configuration of the second predetermined braking portion that provides a strong braking force is complicated.

  SUMMARY OF THE INVENTION An object of the present invention is to make it possible to obtain a strong and stable predetermined braking state with a simple structure in a spinning reel rotor braking device.

  A spinning reel rotor braking device according to a first aspect of the present invention is a device that brakes the rotation of a rotor that is rotatably mounted on a reel body of a spinning reel in the line-feeding direction, and includes a one-way clutch, a rotating member, and a predetermined braking unit. And. The one-way clutch transmits the rotation of the rotor in the yarn unwinding direction. The rotating member is a member that rotates in conjunction with the rotation of the rotor in the yarn unwinding direction transmitted from the one-way clutch. The predetermined braking unit includes a friction member that is mounted on the rotating member so as to be relatively rotatable and frictionally engages with the rotating member, and a switching operation unit. The switching operation unit is disengaged from the friction member and a braking position that engages the friction member to prohibit the rotation of the friction member and causes the friction member to rotate relative to the rotation member to brake the rotation of the rotor in the yarn unwinding direction. Thus, it is mounted on the reel body so as to be switched to a separation position where the rotation of the friction member is permitted and the braking is released.

It further includes at least one friction ring mounted between the friction member and the cylindrical portion, and the friction member is frictionally engaged with the outer peripheral surface of the cylindrical portion via the friction ring.

  In this rotor braking device, when the switching operation portion is arranged at the braking position, the rotation of the friction member is prohibited, and the friction member can be rotated relative to the rotation member. In this state, when the rotor rotates in the yarn feeding direction, the rotation is transmitted to the rotating member via the one-way clutch, and the rotating member rotates. At this time, since the rotation of the friction member is prohibited by the switching operation unit, the rotation member rotates with respect to the friction member whose rotation is prohibited, and the rotation member is braked by the friction member frictionally engaged with the rotation member, A rotor connected to the rotating member by a one-way clutch is braked in a predetermined braking state. Here, since the friction member is mounted in a state of friction engagement with the rotation member, the rotation member can be braked evenly as a whole in a predetermined braking state. For this reason, the rotor can be braked in a powerful and stable predetermined braking state. In addition, since the friction member is attached to the rotating member in a frictionally engaged state, and the friction member is simply switched to rotation prohibition / rotation permission by the switching operation unit, the structure is compared with a structure in which braking is performed by a plurality of disk members.

  A spinning reel rotor braking device according to a seventh aspect of the present invention is the device according to the fourth aspect, wherein the braking lever is swingably attached to the leg portion. In this case, when the swing fulcrum approaches the operation part at the tip of the brake lever and the part acting as a brake moves away from the rocking fulcrum, the movement amount of the operation part relative to the movement amount at the part acting as a brake Since the distance between the fishing rod and the brake lever can be reduced, the entire reel can be reduced in size. Further, by attaching the brake lever to the leg portion, it is not necessary to provide the lever support portion on the housing portion, and the housing portion can be made compact.

[Configuration of braking lever]
As shown in FIG. 1, the brake lever 17 swings around the second axis Y around the reel body 2 by the support shaft 33 mounted on the reel body 2 a of the reel body 2 in the second axis Y direction, which is different from the first axis X. It is supported freely. As shown in FIG. 3, the support shaft 33 is a shaft member with a hook, and is a screw member for mounting the lid member 2d to the housing portion 2f. The support shaft 33 is fixed to the reel body 2 by screwing into a screw 33a inserted from the lid member 2d side. Further, as described above, the brake lever 17 is urged by the coil spring 19 in a direction away from the mounting portion 2c. The brake lever 17 is attached to the reel body 2 so as to be swingable between a brake release position shown in FIG. 7 and a brake position shown in FIG. 5 which is closer to the mounting portion 2c than the brake release position.

  The brake lever 17 is detachably attached to the brake operation portion 17a that is curved from the support portion by the support shaft 33 and extends forward, the brake operation portion 17b that is curved from the support portion and extends obliquely forward and downward, and the brake operation portion 17b. Braking brake 34. Since the brake lever 17 is swingably mounted on the reel body 2a as described above, the swing fulcrum of the support shaft 33 is separated from the brake operation portion 17a at the tip of the brake lever 17, and the braking action portion 17b and the swing fulcrum Approaches. For this reason, a large braking force can be obtained with a light operating force.

  The braking operation portion 17a has a shape that extends forward from the support portion to the vicinity of the outside of the bail arm 9 along the mounting portion 2c, then extends radially outward, and further has a tip curved toward the front. . The first operation portion 17c that can be operated with the index finger of the hand holding the fishing rod forward from the curved portion. The first operation portion 17c is movable in the direction of approaching the mounting portion 2c from the brake release position shown in FIG. As shown in FIGS. 3 and 4, the braking operation portion 17a has a width that extends from the leg portion 2b to the front portion to a portion extending radially outward, and the wide portion 17h includes the mounting portion 2c. A substantially rectangular opening 17e is formed. An operation member 26 of the auxiliary lever 18 described later is exposed from the opening 17e toward the mounting portion 2c. Further, a notch 17g is formed from the wide portion 17h toward the front. An operating member 26 protrudes forward through the notch 17g. A plate-shaped closing plate 35 is screwed into the opening of the notch 17g in order to prevent fishing line from entering through the gap between the brake lever 17 and the auxiliary lever 18 and causing line scum.

  The distal end of the braking action portion 17b is arranged to face the inner peripheral side of the braking cylinder 41, and a braking shoe 34 that can contact the inner peripheral surface of the braking cylinder 41 is detachable at the distal end as shown in FIG. It is attached. The brake shoe 34 is made of, for example, a synthetic resin having elasticity, such as a polyamide-based synthetic resin or polyacetal, and presses the brake cylinder 41 radially outward by swinging of the brake lever 17.

  The brake lever 17 is biased by the coil spring 19 when nothing is operated, and is disposed at the brake release position so that the brake shoe 34 is separated from the brake cylinder 41 as shown in FIG.

  The coil spring 19 is disposed in a compressed state between the braking operation portion 17 a of the braking lever 17 and the leg portion 2 b of the reel body 2. The coil spring 19 urges the brake lever 17 counterclockwise in FIG. 1 toward the brake release side. As a result, when the hand is released from the brake lever 17, the rotor 3 enters the brake release state.

[Configuration of auxiliary lever]
The auxiliary lever 18 is for performing an operation of switching the predetermined braking portion 21 between a braking release state shown in FIG. 7 and a predetermined braking state shown in FIG. As shown in FIG. 7, the auxiliary lever 18 includes a brake release position where a second operation portion 26a (described later) is disposed at a second position close to the mounting portion 2c, and a second operation portion as shown in FIG. 26a swings between a predetermined braking position arranged at a third position separated from the mounting portion 2c. As shown in FIGS. 1, 3 and 4, the auxiliary lever 18 includes a plate-like first lever member 25 supported on the reel body 2 so as to be swingable about the second axis Y on the support shaft 33, and a first lever member 25. 1 has an operation member 26 mounted on the lever member 25.

  The first lever member 25 is arranged side by side on the front side surface of the brake lever 17 in FIG. The first lever member 25 extends upward and forward and downward and forward along the brake lever 17 from the support portion, and an operation member 26 is fixed to a front end of the front and upward by, for example, two screws 25a. . The tip of the first lever member 25 is located in the opening 17e of the wide portion 17h of the braking operation portion 17a of the braking lever 17. Further, the base end of the first lever member 25 that extends obliquely forward and downward from the support portion is disposed radially inward and rearward of the braking portion 16. At the base end of the first lever member 25, a rectangular locking notch 25 c (FIG. 2) in which the tip of the second lever member 27 of the predetermined braking portion 21 is locked is formed. The locking notch 25 c is a rectangular notch that opens to the base end side having an area larger than the transverse area of the distal end portion of the second lever member 27.

  The operation member 26 has a second operation portion 26a at the tip. The second operation portion 26a is disposed on the side away from the mounting portion 2c so as to face the first operation portion 17c. For this reason, the 2nd operation part 26a can be pushed in with the index finger of the hand which grasps a fishing rod. The first operation unit 17c and the second operation unit 26a can perform a pull-in operation and a push-in operation with the same finger. The second operating portion 26a is disposed at the second position shown in FIGS. 1 and 7 and the third position shown in FIG.

  The operating member 26 extends forward through the space surrounded by the notch 17g and the blocking plate 35 from the lower portion of the opening 17e, and a second operating portion 26a is formed at the extended tip. As described above, since the second operation portion 26a extends forward through the space surrounded by the notch 17g and the blocking plate 35, the periphery of the second operation portion 26a, in particular, a portion close to the bail arm 9 is a space. Surrounded by For this reason, even if the fishing line comes into contact with this portion due to the dandruff, the fishing line is less likely to be caught in the gap between the operation member 26 and the brake lever 17 (line scum). Further, since the notch 17g is closed by the closing plate 35, the space can be closed by attaching the closing plate 35 after the operation member 26 is attached. For this reason, it becomes easy to attach the operation member 26.

  Further, when the auxiliary lever 18 is disposed at the predetermined braking position, as shown in FIG. 6, the lower surface of the second operation portion 26a substantially comes into contact with the closing plate 35 of the braking operation portion 17a. As a result, when the auxiliary lever 18 is in the predetermined braking position, the auxiliary lever 18 swings to the braking release position in conjunction with the swing of the braking lever 17 in the direction approaching the mounting portion 2c.

[Configuration of the specified braking part]
As shown in FIG. 3, the predetermined braking unit 21 includes a second lever member 27 (an example of a switching operation unit) that swings in conjunction with the first lever member 25, and a second lever member 27 that has a predetermined braking release position. A toggle spring 28 is held at the braking position, and a friction member 29 is attached to the tubular member 40 so as to be relatively rotatable and frictionally engages with the tubular member 40. As shown in FIGS. 3 and 8, the second lever member 27 is swingably mounted on a swing shaft 27 a disposed in parallel with the spool shaft 8 at the front portion of the reel body 2. The distance from the base end of the second lever member 27 to the swing center is at least twice as long as the distance from the tip to the swing center. The tip of the second lever member 27 is locked to the locking notch 25c, and the second lever member 27 is interlocked with the first lever member 25 and the brake release position (FIG. 8A) and the predetermined braking. It swings between the positions (FIG. 8 (b)).

  Here, the base end of the second lever member 27 is urged by the toggle spring 28 when in the braking release position and contacts the upper surface of the locking notch 25c, and contacts the lower surface when in the predetermined braking position. In the middle of the second lever member 27, an engagement member 39 is provided that engages a friction member 29 having a tip attached to the cylindrical member 40. The engaging member 39 is integrally formed with the mounting portion 27 c mounted in the middle of the second lever member 27, and extends from the mounting portion 27 c in the substantially radial direction of the tubular member 40. The second lever member 27 extends further in a curved manner from the mounting portion of the engaging member 39, and the toggle spring 28 is mounted on the extended base end.

  As shown in FIGS. 9 to 11, the friction member 29 is mounted in an annular groove 40 d formed on the outer peripheral surface of the outer cylindrical portion 40 a of the cylindrical member 40. The friction member 29 includes two substantially semicircular divided members 29a and 29b each having a shape obtained by cutting a ring in half. Each divided member 29a, 29b is a member formed by press-molding a metal thin plate, for example. Each of the split members 29a and 29b has a plurality of C-shaped friction portions 37 that are frictionally engaged with the cylindrical member 40 so as to be relatively rotatable, and a plurality of engagement members 39 that are moved to the braking position. Each of the engaging portions 38. Each of the divided members 29a and 29b is pressed against the annular groove 40d by a spring member 30 mounted in a mounting groove 37a formed in the friction portion 37. The spring member 30 is made of, for example, an elastic wire made of a metal and curved in an annular shape.

  The engaging portion 38 is a cylindrical portion extending rearward from the friction portion 37, and has a large number of engaging recesses 38 a formed at one end thereof at intervals in the circumferential direction. The front end of the engagement member 39 can be engaged with the engagement recess 38a. For example, 20 or more engaging recesses 38a are formed in each of the divided members 29a and 29b. By forming such a large number of engaging recesses 38a, the engaging member 39 can be easily engaged with the engaging recesses 38a when the second lever member 27 is swung to a predetermined braking position.

  In the friction member 29 having such a configuration, when the second lever member 27 is disposed at a predetermined braking position and the engagement member 39 is engaged with the engagement recess 38 a of the engagement portion 38, the friction portion 37 is the tubular member 40.

When the second lever member 27 is swung to the predetermined brake position, the second lever member 27 is also swung from the brake release position to the predetermined brake position. As a result, the engaging member 39 engages with the engaging portion 38 of the friction member 29 and brakes the rotation of the rotor 3 in the yarn unwinding direction in a predetermined braking state.

  As shown in FIGS. 3 and 8, the toggle spring 28 biases the second lever member 27 and urges the second operation portion 26a to be distributed between the second position and the third position, and maintains its posture. can do. The toggle spring 28 is a torsion coil spring attached to the base end of the second lever member 27. One end of the toggle spring 28 is locked to the base end of the second lever member 27, and the other end is locked to the front end surface of the reel body 2a. As shown in FIG. 8A, the toggle spring 28 urges the second lever member 27 in the clockwise direction of FIG. 8A when the second lever member 27 is disposed at the braking release position. When placed in the braking position, it is biased counterclockwise in FIG. As a result, the second lever member 27 is held at the brake release position and the predetermined brake position, and the first lever member 25 is held at the brake release position and the predetermined brake position.

  Here, since the distance from the base end of the second lever member 27 to the swing center is more than twice as long as the distance from the tip to the swing center, when the first lever member 25 swings, the swing is second. The lever member 27 appears at the base end side of the lever member 27 with a swing distance more than twice, and the toggle spring 28 can be easily reversed.

[Reel operation and operation]
At the time of casting, the fishing line is fed out from the outer periphery of the spool 4 by tilting the bail arm 9 toward the line releasing posture and casting. At the time of winding the yarn, if the handle 1 is rotated in the yarn winding direction, the bail arm 9 returns to the yarn winding posture by a return mechanism (not shown). The rotational force of the handle 1 is transmitted to the pinion gear 12 via the handle shaft 10 and the master gear 11. The rotational force transmitted to the pinion gear 12 is transmitted to the rotor 3 via the front portion 12a of the pinion gear. At this time, since the rotor 3 rotates in the yarn winding direction, the rotational force is not transmitted to the tubular member 40 by the action of the one-way clutch 32. When the pinion gear 12 rotates, the spool shaft 8 reciprocates in the front-rear direction.

  If nothing is operated on the brake lever 17, the brake lever 17 is pressed by the coil spring 19 and arranged on the brake release position side. At this time, if the second operation portion 26a of the auxiliary lever 18 is disposed at the second position, the brake shoe 34 is separated from the brake cylinder 41 and engaged as shown in FIGS. The member 39 is separated from the engaging portion 38, and the rotor 3 is in a brake release state.

  When exchanging with the fish by reversing the rotor 3, the braking force is adjusted by pulling the first operating portion 17c of the braking lever 17 toward the mounting portion 2c with, for example, an index finger.

  When the fishing line is pulled by the fish and the rotor 3 reverses in the line-feeding direction, the rotational force is transmitted to the tubular member 40 via the one-way clutch 32 and further to the braking cylinder 41. As a result, the brake cylinder 41 rotates integrally with the rotor 3. When the first operating portion 17c of the brake lever 17 is pulled in the direction approaching the mounting portion 2c, even if the second lever member 27 is at the predetermined braking position, the closing plate 35 is operated as shown in FIG. The second operating portion 26a is pressed in the direction approaching the mounting portion 2c, the auxiliary lever 18 swings from the predetermined braking position to the braking releasing position side in conjunction with the braking lever 17, and the second lever member 27 releases the braking. Swings to the position side. As a result, the predetermined braking state by the predetermined braking unit 21 is once released. At this time, the toggle spring 28 is reversed by the swing of the second lever member 27, the second lever member 27 is urged to the brake release position side, and the first lever member 25 is held on the brake release position side (FIG. 8 (a)).

  In this state, when the brake lever 17 is further operated in a direction approaching the mounting portion 2c, the brake shoe 34 of the brake lever 17 strongly presses the inner peripheral surface of the brake cylinder 41 radially outward. This braking force can be adjusted by adjusting the force applied to the braking lever 17, and the amount of reverse rotation of the rotor 3 can be adjusted arbitrarily. As a result, a braking force corresponding to the operating force of the braking lever 17 is applied to the rotor 3. As described above, even if the user forgets to release the predetermined braking state, the predetermined braking state can be canceled by merely pulling the brake lever 17.

  When the fishing ground is moved or the reel is stored, the second operation portion 26a of the auxiliary lever 18 is pushed in a direction away from the mounting portion 2c while the hand is released from the first operation portion 17c. Then, as shown in FIGS. 6 and 8B, the auxiliary lever 18 swings from the brake release position to the predetermined brake position, and the second lever member 27 swings from the brake release position to the predetermined brake position. It is held in that position by a spring 28. At the predetermined braking position, the lower surface of the second operation portion 26a is substantially in contact with the closing plate 35. As a result, the engagement member 39 engages with the engagement recess 38a of the friction member 29, and the rotation of the friction member 29 is prevented, and the reverse rotation of the rotor 3 is prevented.

The braking force at this time is determined by the degree of press contact of the friction member 29 to the annular groove 40d of the friction member 29, in this reference example , the urging force of the spring member 30. For this reason, it becomes easy to obtain a predetermined braking force that is strong enough that the handle 1 does not rotate even if something hits the handle 1 during the movement, and the predetermined braking force can be set so strong that no dandruff occurs during the movement of the fishing ground. . Further, since braking is performed by the relative rotation between the friction member 29 and the cylindrical member 40, the braking force is less likely to fluctuate and is stabilized.

  Further, in order to change the hanging length of the device, or to make the fish bite into the device when it hits the fish, when the rotor 3 is desired to be released from the predetermined braking state, the braking lever 17 is What is necessary is just to operate in the direction which approaches the mounting part 2c slightly. Then, as shown in FIG. 6 described above, the second operating portion 26a is pressed by the brake lever 17, and the auxiliary lever 18 swings to the brake release position side. As a result, the second lever member 27 swings to the braking release position, and the predetermined braking state is once released. Of course, the predetermined braking state can be released even if the second operation portion 26a is pulled.

  Here, since the friction member 29 is mounted in a state of frictional engagement with the tubular member 40, the rotor 3 can be braked through the tubular member 40 evenly in a predetermined braking state. . For this reason, the rotor 3 can be braked in a strong and stable predetermined braking state. In addition, the friction member 29 is attached to the cylindrical member 40 in a frictionally engaged state, and the friction member 29 only needs to be switched to rotation inhibition / permission by the second lever member 27, so that braking is performed with a plurality of disk members. The structure is simple compared to the structure.

For this purpose, there are three friction rings 130 made of, for example, O-rings mounted in the annular groove 140d.

  As shown in FIGS. 16 and 17, the lever member 127 is swingably mounted on a swing shaft 127 a disposed in front of the reel body 102 in parallel with the spool shaft 108. The distance from the base end of the lever member 127 to the swing center is two times longer than the distance from the tip to the swing center. The distal end of the lever member 127 is locked to the locking notch 117e, and the lever member 127 is interlocked with the brake lever 117 to release the braking position (FIG. 17A) and the predetermined braking position (FIG. 17B). )).

It is energized. The toggle spring 128 is locked to the base end of the lever member 127.

  Here, the base end of the lever member 127 is urged by the toggle spring 128 when in the braking release position and contacts the upper surface of the locking notch 117e, and contacts the lower surface when in the predetermined braking position. A locking claw 170 is swingably attached to the intermediate portion of the lever member 127. The locking claw 170 has a spring locking portion 170a at the base end and an acute-angle claw portion 170b at the tip, and in a direction in which the claw portion 170b protrudes by the coil spring 171 (counterclockwise in FIG. 16). It is energized. One end of the coil spring 171 is locked to the spring locking portion 170 a and the other end is locked to the swing shaft of the lever member 127. When the latching claw 170 is swingably attached to the lever member 127 and biased in the direction in which the claw portion 170a protrudes by the coil spring 171, the lever member 127 is swung to a predetermined braking position. Even if the claw portion 170b contacts the protruding portion of the second concavo-convex portion 129a because the rotation phase of the claw portion 170b and the first concavo-convex portion 129a of the friction member 129, which will be described later, does not match, the shock is absorbed and the friction is ensured. The member 129 can be prevented from rotating.

  The friction member 129 is a cylindrical member and is rotatably mounted on the outer periphery of the cylindrical member 140. On the inner peripheral surface of one end (the right end in FIG. 13) of the friction member 129, a sawtooth-shaped second uneven portion 129a that engages with the claw portion 170b of the locking claw 170 is formed so as to protrude radially inward. The second concavo-convex portion 129a is provided for engaging the locking claw 170 and prohibiting the rotation of the friction member 129 in the yarn unwinding direction when the lever member 127 is in the predetermined braking position (FIG. 17B). ing. Between the other end (the left end in FIG. 13) of the friction member 129 and the outer surface of the disc portion 140c of the cylindrical member 140, for example, an ear washer 172 having six radial protrusions on the outer peripheral portion, and a holed circle A plate-shaped first washer 173 is attached. The washer 172 with the ear is non-rotatably locked in, for example, six locking grooves 129b formed at intervals in the circumferential direction from one end surface of the friction member 129 toward the other end side. The washer 172 with the ear and the first bearing washer 173 are prevented from coming off by a retaining spring 174 that is curved in a C shape. The retaining spring 174 is attached to an annular groove 129 c formed on the inner peripheral surface of the other end of the friction member 129. A second washer 175 is mounted between the second uneven portion 129 a and the tubular member 140. These washers 172, 173, and 175 are provided so that the friction member 129 does not rattle by adjusting the axial mounting dimension of the friction member 129.

  In the friction member 129 having such a configuration, when the lever member 127 is disposed at a predetermined braking position and the locking claw 170 is engaged with the second uneven portion 129 a, the friction member 129 is acted on by the friction ring 130 so that the tubular member 140. Friction sliding against.

  Here, when the brake lever 117 is pushed into the predetermined brake position, the lever member 127 is also swung from the brake release position to the predetermined brake position in conjunction therewith. As a result, the locking claw 170 is engaged with the second uneven portion 129a of the friction member 129, and the rotation of the rotor 103 in the yarn unwinding direction is braked in a predetermined braking state.

  As shown in FIGS. 16 and 17, the toggle spring 128 can urge the lever member 127 to urge the brake lever 117 to a predetermined brake position and a brake release position, thereby maintaining the posture. The toggle spring 128 is a torsion coil spring attached to the base end of the lever member 127. One end of the toggle spring 128 is locked to the base end of the lever member 127, and the other end is locked to the front end surface of the reel body 102a. As shown in FIG. 17A, the toggle spring 128 biases the lever member 27 in the clockwise direction of FIG. 17A when the lever member 127 is arranged at the brake release position, and is arranged at the predetermined braking position. Then, it is urged counterclockwise in FIG. Accordingly, the lever member 127 is held at the brake release position and the predetermined brake position, and the brake lever 117 is further held at the brake release position and the predetermined brake position.

  Again, since the distance from the base end of the lever member 127 to the swing center is more than twice as long as the distance from the tip to the swing center, when the brake lever 117 swings, the swing is the base end of the lever member 127. As a result, the toggle spring 128 can be easily reversed.

[Reel operation and operation]
At the time of casting, the fishing line is fed out from the outer periphery of the spool 104 by tilting the bail arm 109 toward the line releasing posture and casting. At the time of winding the yarn, if the handle 101 is rotated in the yarn winding direction, the bail arm 109 returns to the yarn winding posture by a return mechanism (not shown). The rotational force of the handle 101 is transmitted to the pinion gear 112 via the handle shaft 110 and the master gear 111 as in the reference example . The rotational force transmitted to the pinion gear 112 is transmitted to the rotor 103 via the front portion 112a of the pinion gear. At this time, since the rotor 103 rotates in the yarn winding direction, the rotational force is not transmitted to the tubular member 140 due to the action of the one-way clutch 132. When the pinion gear 112 rotates, the spool shaft 108 reciprocates in the front-rear direction.

  If no operation is made on the brake lever 117, the brake lever 117 is pressed by the action of the coil spring 119 and the predetermined brake portion 121 and is disposed at the brake release position or the predetermined brake position.

  When the rotor 103 is reversed to interact with fish, the braking force is adjusted by pulling the first operating portion 117c of the braking lever 117 toward the mounting portion 102c with, for example, an index finger.

  When the fishing line is pulled by the fish and the rotor 103 is reversed in the line-feeding direction, the rotational force is transmitted to the tubular member 140 via the one-way clutch 132 and further to the brake cylinder 141. As a result, the brake cylinder 141 rotates integrally with the rotor 103. When the first operation portion 117c of the brake lever 117 is pulled in the direction approaching the mounting portion 102c, the lever member 127 swings toward the brake release position even if the brake lever 117 is at the predetermined braking position. As a result, the predetermined braking state by the predetermined braking unit 121 is once released. At this time, the toggle spring 128 is reversed by the swing of the lever member 127, the lever member 127 is urged toward the brake release position, and the lever member 127 is held at the brake release position (FIG. 17A).

  In this state, when the brake lever 117 is further operated in a direction approaching the mounting portion 102c, the brake shoe 134 of the brake lever 117 strongly presses the inner peripheral surface of the brake cylinder 141 radially outward. This braking force can be adjusted by adjusting the force applied to the braking lever 117, and the amount of reverse rotation of the rotor 103 can be adjusted arbitrarily. As a result, a braking force corresponding to the operating force of the braking lever 117 is applied to the rotor 103. In this way, even if the user forgets to release the predetermined braking state, the predetermined braking state can be canceled simply by pulling the brake lever 117.

  When moving the fishing ground or storing the reel, the hand is released from the first operation part 117c and the second operation part 117d is pushed in the direction away from the mounting part 102c. Then, as shown in FIGS. 16 and 17B, the lever member 127 swings from the brake release position to the predetermined brake position and is held at that position by the toggle spring 128. As a result, the locking claw 170 engages with the second uneven portion 129a of the friction member 129, the rotation of the friction member 129 is prevented, and the reverse rotation of the rotor 103 is prevented.

  The braking force at this time is determined by the elastic force of the friction ring 130 mounted between the friction member 129 and the cylindrical member 140. For this reason, it becomes easy to obtain a predetermined braking force that is strong enough that the handle 101 does not rotate even if something hits the handle 101 during the movement, and the predetermined braking force can be set so strong that no thread dander occurs during the movement of the fishing ground. . Further, since braking is performed by the relative rotation between the friction member 129 and the cylindrical member 140, the braking force is less likely to fluctuate and is stabilized.

  Further, in order to change the hanging length of the device or to make the fish bite into the device reliably when the fish hits, the brake lever 117 is set to release the brake from the predetermined braking state. What is necessary is just to operate in the direction which approaches the mounting part 102c slightly. Then, as described above, the brake lever 117 causes the two lever member 127 to swing to the brake release position, and the predetermined brake state is once released.

  Also here, since the friction member 129 is mounted in a state of frictional engagement with the cylindrical member 140, the rotor 103 can be braked uniformly through the cylindrical member 140 as a whole in a predetermined braking state. . For this reason, the rotor 103 can be braked in a powerful and stable predetermined braking state. In addition, since the friction member 129 is attached to the cylindrical member 140 in a frictionally engaged state, and the friction member 129 only needs to be switched to rotation prohibition / rotation permission by the lever member 127, a structure in which braking is performed by a plurality of disk members is provided. The structure is simpler than that.

(A) In the reference example , the engagement member 39 is provided on the second lever member 27, but the engagement member may be provided on the first lever member 25.

(B) In the reference example , the friction member is formed by the two divided members 29a and 29b and the spring member 30, but the friction member may be formed by one member. For example, as shown in FIGS. 18 and 19, the friction member 229 includes an annular member 230 that is partially cut out and has an elastic force, and the annular member 230 is formed in the annular groove 40 d of the tubular member 40 by the elastic force. It is in pressure contact. The annular member 230 is provided with an annular leaf spring portion 237 having a frictional portion 237a formed on the inner periphery and partially cut away and having an elastic force, and radially projecting radially outward of the outer periphery of the leaf spring portion 237. And a plurality of projecting portions 238 forming the engaging portion 238a. The non-divided friction member 229 attached to the annular groove 40d with its own elastic force having such a configuration may be used.

[Other Embodiments]
(C) Although the O-ring is used as the friction ring 130 in the embodiment, the friction ring is not limited to the O-ring.

  (D) In the above embodiment, the brake levers 17 and 117 are swingably mounted on the reel bodies 2a and 102a. However, as shown in FIG. 20, the brake lever 217 is attached to the support shaft 233 provided on the leg 202b. You may mount so that rocking is possible. Also in this case, the coil spring 219 that urges the brake lever 217 in the brake release direction is disposed on the first operating portion 217 c side of the support shaft 233. In such a configuration, the second axis Y ′ that is the swing fulcrum approaches the first operation part 217c that is the operation part at the tip of the brake lever 217, and the braking action part 217b that acts as a brake acts on the second axis Y ′. By moving away from the movement amount, the movement amount of the first operation portion 217c can be reduced relative to the movement amount of the braking action portion 217b. For this reason, the space | interval of a fishing rod and the brake lever 217 can be narrowed, and the whole reel can be reduced in size. Further, by mounting the brake lever 217 on the leg 202b, it is not necessary to provide the support shaft 233 of the brake lever 217 on the housing 202f, and the housing 202f can be made compact.
