A brake lever (an example of a brake operation member) 17, a spring member 19 in the form of a coil spring that biases the brake lever 17, and a predetermined brake unit 21 (switchable between a predetermined brake state and a brake release state by the brake lever 17. 3). The spring member 19 functions as a biasing member that biases the braking lever 17 in a direction away from the saddle mounting portion 2c.

<Configuration of braking unit>
As shown in FIG. 4, the braking unit 16 includes a braking unit body 31 having a braking surface 41 a that is braked by pressing the tip of the braking lever 17, the rotor 3, and the braking unit body 31 in the rotational direction of the rotor 3. A claw-type one-way clutch 32 is connected and disconnected accordingly.

  The brake part main body 31 includes a cylindrical member 40 disposed concentrically with the rotor 3 on the inner peripheral side of the cylindrical part 3 a of the rotor 3, and a brake cylinder 41 fixed to the inner peripheral surface of the cylindrical member 40. ing.

  As shown in FIG. 4, the cylindrical member 40 includes an outer cylindrical portion 40 a disposed concentrically on the inner peripheral side of the cylindrical portion 3 a, and an inner cylindrical portion 40 b disposed on the inner peripheral side of the outer cylindrical portion 40 a This is a double cylindrical member having a disc part 40c that connects the outer cylinder part 40a and the inner cylinder part 40b. On the outer peripheral surface of the outer cylinder portion 40a, an annular groove 40d to which a friction ring 30 constituting a predetermined braking portion 21 described later is attached is formed, for example, at intervals in the two-axis direction. The inner cylinder portion 40b is rotatably supported by the bearing 14d on the outer peripheral surface of the bearing retaining ring 54 fixed to the mounting member 2e. The inner cylinder portion 40b extends further radially inward from the front side of the bearing 14d, and is opposed to the outer peripheral side of the boss portion 3f in a cylindrical shape. An elastic seal member 86 is mounted between the opposing portions of the boss portion 3f and the inner cylinder portion 40b. This makes it difficult for liquid to enter the bearing 14 c, the bearing 14 d, and the inside of the reel body 2 from the gap between the boss portion 2 f of the rotor 3 and the cylindrical member 40.

  The bearing retaining ring 54 is screwed and fixed to the inner peripheral surface of the tip end of the mounting member 2e. A bearing 14 c is disposed between the bearing retaining ring 54 and the pinion gear 12. The bearing 14c supports the pinion gear 12 and also functions to prevent the bearing retaining ring 54 from coming off. As shown in FIG. 5, the bearing retaining ring 54 is a cylindrical member formed by cutting, for example, an aluminum alloy. The bearing retaining ring 54 has a large-diameter flange portion 54a formed at the tip and a fixing screw portion 54b formed on the outer peripheral surface of the rear end. A cylindrical bearing collar 87 is disposed between the bearing 14c and the bearing 14a. Thereby, the rear part of the bearing 14c is positioned. The front portion of the bearing 14 c is positioned in contact with the boss portion 3 f of the rotor 3.

  The brake cylinder 41 extends from the inner peripheral surface of the outer cylinder portion 40a toward the rear surface of the bearing 14d via the inner cylinder portion 40b. Therefore, the outer ring of the bearing 14d is sandwiched between the tubular member 40 and the brake cylinder 41. As for the brake cylinder 41, the inner peripheral surface along the outer cylinder part 40a becomes the brake surface 41a. The brake cylinder 41 is a metal bottomed cylindrical member having a center hole 41b, and is fixed to the disk portion 40c with screws. The center hole 41b is formed in a cylindrical shape so as to face the outer peripheral side of the mounting member 2e. The tip of the brake lever 17 comes into contact with the brake surface 41a of the brake cylinder 41 to brake the cylindrical member 40. An elastic seal member 88 is mounted between the central hole 41b of the brake cylinder 41 and the mounting member 2e. This prevents liquid from entering the bearing 14d. Further, the liquid is prevented from entering the inside of the reel body 2 through the bearing 14d.

  The one-way clutch 32 is of a claw type, and connects the rotor 3 and the tubular member 40 of the brake section main body 31 only when the rotor 3 rotates in the yarn drawing direction. Rotate in the direction of thread feeding. Therefore, when the rotor 3 rotates in the yarn winding direction, the rotor 3 and the cylindrical member 40 are disconnected, and the rotation is not transmitted from the rotor 3 to the cylindrical member 40. As shown in FIGS. 4 and 5, the one-way clutch 32 can swing freely on a ring-shaped ratchet wheel 42 fixed to the front wall 3 d of the cylindrical portion 3 a of the rotor 3 and a disk portion 40 c of the cylindrical member 40. Between the ratchet wheel 42 and the front wall 3d. And a vibration isolating member 45 disposed on the surface.

  As shown in FIG. 4, the ratchet wheel 42 is fixed to the rear surface of the front wall 3 d of the cylindrical portion 3 a of the rotor 3 by a plurality of mounting screws 46. The ratchet wheel 42 has a disk-like flange portion 42a fixed to the front wall 3d, and a cylindrical portion 42c in which sawtooth-like ratchet teeth 42b are formed on an inner peripheral surface integrally formed with the flange portion 42a. is doing. A vibration isolating member 45 is mounted between the flange portion 42a and the rear surface of the front wall 3d.

  The ratchet pawl 43 is swingably provided in the disc portion 40c at an engagement position where the ratchet pawl 43 is engaged with the ratchet teeth 42b and an engagement release position where the ratchet pawl 43 is disengaged from the ratchet teeth 42b. The ratchet claw 43 has a claw portion 43a sharpened at an acute angle that meshes with the ratchet teeth 42b. Further, an oval locking hole 43c for locking the urging member 44 is formed.

As shown in FIG. 5, the urging member 44 is a member formed by bending and bending a metal wire having a spring property into a question mark shape. The urging member 44 includes a circular portion 44a that is mounted in pressure contact with a spring mounting groove 3g (FIG. 4) formed in the boss portion 3f of the rotor 3, and an arm portion 44b that extends radially outward from the circular portion 44a. The arm portion 44b has a locking projection 44c that is bent toward the locking hole 43c. The locking projection 44c is inserted into the locking hole 43c and can press the inner surface of the locking hole 43c in both directions. The free diameter of the circular portion 44a is smaller than the bottom diameter of the spring mounting groove 3g. For this reason, the urging member 44 is a bi-directional urging member that can urge the ratchet pawl 43 in both directions (and in the meshing release direction). Specifically, the urging member 44 includes the spring mounting groove 3g. The ratchet pawl 43 is urged in both directions of the meshing direction and the meshing release direction.

  As a result, when the rotor 3 rotates in the yarn winding direction (clockwise in FIG. 5), the urging member 44 also rotates in the same direction, and the ratchet pawl 43 is engaged and urged in the release direction. Then, the ratchet pawl 43 swings to the mesh release position side. For this reason, when the rotor 3 rotates in the yarn winding direction, the rotation of the rotor 3 is not transmitted to the tubular member 40 and the ratchet pawl 43 does not intermittently collide with the ratchet wheel 42. As a result, the noise of the one-way clutch 32 can be reduced, and the rotational resistance when rotating in the yarn winding direction can be reduced.

  Further, when the rotor 3 rotates in the yarn feeding direction (counterclockwise in FIG. 5), the urging member 44 also rotates in the same direction and urges the ratchet pawl 43 in the meshing direction. Then, the ratchet pawl 43 swings toward the meshing position, and the ratchet teeth 42 b mesh with the pawl portion 43 a of the ratchet pawl 43. For this reason, when the rotor 3 rotates in the yarn drawing-out direction, the rotation of the rotor 3 is transmitted to the tubular member 40 and the braking operation by the lever brake mechanism 6 becomes possible.

  Here, in the internal gear type one-way clutch 32 in which the ratchet teeth 42b are formed on the inner peripheral surface, the ratchet pawl 43 can be urged in both directions by one urging member 44. Two functions of noise reduction and rotation transmission can be realized by one urging member 44.

  The vibration isolation member 45 is a washer-shaped sheet member made of synthetic rubber having elasticity such as NBR and urethane rubber. As described above, the vibration isolation member 45 is disposed between and in contact with the flange portion 42a of the ratchet wheel 42 and the front wall 3d. The anti-vibration member 45 is provided so that when the ratchet teeth 42 b collide with and engage with the ratchet pawl 43, the vibration due to the collision is absorbed and the vibration is not transmitted from the ratchet wheel 42 to the rotor 3.

<Configuration of braking lever>
As shown in FIG. 1, the brake lever 17 is swung around the second axis Y by the support shaft 33 attached to the leg 2b 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. 6, the support shaft 33 is a hooked shaft-shaped nut member for mounting the lid member 2d on the reel body 2a. The support shaft 33 is fixed to the reel body 2 by screwing into a screw member 33a inserted from the lid member 2d side. Further, as described above, the brake lever 17 is urged by the spring member 19 in a direction away from the rod mounting portion 2c.

  As described above, the mounting groove 2g is formed on the front surface of the leg 2b, and the seat member 7 is mounted in the mounting groove 2g. As shown in FIGS. 1 and 3, the sheet member 7 is connected to the pair of generally crescent-shaped wall portions 7a contacting the wall surface of the mounting groove 2g and the bottom surface of the mounting groove 2g. And a bottom portion 7b. The wall 7a is formed with a passage hole 7d through which the support shaft 33 can pass. A spring cylinder portion 7c that houses the spring member 19 is formed on the bottom portion 7b. The sheet member 7 is prevented from coming off from the mounting groove 2g by the support shaft 33.

  The brake lever 17 is attached to the reel body 2 so as to be swingable between a predetermined braking position indicated by a one-dot chain line in FIG. 1 and a braking position closer to the saddle mounting portion 2c than a braking release position indicated by a two-dot chain line. Yes. The brake lever 17 is normally held at either the brake release position indicated by the solid line in FIG. 1 or the predetermined brake position indicated by the alternate long and short dash line by the mechanism of the spring member 19 and the predetermined brake portion 21.

  The brake lever 17 extends from the mounting portion 17b, an operation portion 17a for performing a braking operation, a mounting portion 17b supported by the mounting groove 2g of the leg portion 2b so as to be swingable about the second axis Y by the support shaft 33, and the mounting portion 17b. And a braking action portion 17c for braking the braking portion 16.

  The operation unit 17a is, for example, an aluminum alloy member and is manufactured by forging. The operating portion 17a is detachably connected to the mounting portion 17b by a plurality of (for example, two) fixing members (for example, bolt members) 90 to the mounting portion 17b. The operating portion 17a extends forward from the connecting portion to the mounting portion 17b to the vicinity of the outer side of the bail arm 9 along the saddle mounting portion 2c, and then branches and extends radially outward and forward. The tip branched outward is curved forward. A portion having a curved shape in front of the operation portion 17a is a pull-in operation portion 17d. The pull-in operation unit 17d is used, for example, when the rotor 3 is braked according to an operation force by performing a pull-in operation with an index finger of a hand holding a fishing rod (for example, a left hand). Further, a portion extending forward from the mounting portion 17b is a first push operation portion 17e, and a portion connected to the mounting portion 17b is a second push operation portion 17f. The first pushing operation unit 17e and the second pushing operation unit 17f are used when switching to the predetermined braking unit 21. The first push operation unit 17e is used when a push operation is performed with an index finger of a hand holding a fishing rod. The second push operation unit 17f is used when a push operation is performed with the middle finger of a hand holding a fishing rod.

  As shown in FIG. 7, a name plate 91 formed by bending a thin metal plate material by press molding is detachably attached to the second pushing operation portion 17f. The inscription plate 91 has a Γ-shaped cross section, and the upper surface 91a thereof is disposed so as to face the saddle mounting portion 2c and is formed so as to be slightly convex upward in a sectional view. The name plate 91 is provided to improve the design of the appearance while improving the contact with the finger when the second pressing operation portion 17f is pressed with the back of the middle finger. The second pushing operation portion 17f is formed with an insertion groove 17g into which the tip portion of the mounting portion 17b is inserted. The insertion groove 17g is formed so as to open on the heel mounting portion 2c side. Thereby, when operating the pulling-in operation part 17d where the most force is applied by the operation of the operation part 17a, the force is efficiently transmitted from the bottom part of the insertion groove 17g to the tip part of the mounting part 17b. The insertion groove 17g has a groove width in which the nameplate 91 can be inserted side by side with the mounting portion 17b. A fixing member 90 is mounted through the insertion groove 17g, and the fixing member 90 fixes the nameplate 91 in addition to the mounting portion 17b.

  By the pull-in operation using the pull-in operation unit 17d, the brake lever 17 swings from the brake release position indicated by the solid line toward the brake position approaching the rod mounting part 2c indicated by the two-dot chain line. Further, by the pushing operation using the first pushing operation portion 17e or the second pushing operation portion 17f, the braking lever 17 is directed from the braking release position indicated by the solid line to the predetermined braking position separated from the rod mounting portion 2c indicated by the alternate long and short dash line. Swing.

  The mounting portion 17b and the braking action portion 17c are plate-like members made of, for example, stainless steel, which are integrally formed by bending in a C shape. The mounting portion 17b is disposed in the sheet member 7 so as not to contact the leg portion 2b of the reel body 2. Thereby, electrolytic corrosion of the reel body 2 made of magnesium alloy can be prevented. A fitting hole 17h into which the support shaft 33 is fitted is formed in the mounting portion 17b.

  The distal end of the braking action portion 17c 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. As shown in FIG. 8, a first mounting recess 17j is formed in the upper portion and a second mounting recess 17k is formed in the lower portion of the braking shoe 34 of the braking action portion 17c. Further, behind the attachment portion of the braking shoe 34 of the braking action portion 17c, the engagement portion 17i is engaged with a substantially elliptical locking hole 17i with which a tip of a lever member 27 described later of the predetermined braking portion 21 is engaged. As shown in FIG. 8, the locking hole 17i is formed with a rear portion wider than the front portion in order to prevent interference with the lever member 27 when the braking lever 17 is operated in a braking state indicated by a two-dot chain line. Has been. Thereby, when the brake lever 17 is operated to the braking position, it is possible to prevent the maximum braking force from being lowered.

  The brake shoe 34 is made of a synthetic resin having elasticity such as a polyamide-based synthetic resin or polyacetal. As shown in FIG. 1, the brake shoe 34 presses the brake cylinder 41 radially outward by swinging the brake lever 17. As shown in FIGS. 8 and 9, the brake shoe 34 includes a contact portion 34 a that contacts the brake cylinder 41, and a pair of mounting leg portions 34 b that contact both side surfaces of the braking action portion 17 c from the lower surface of the contact portion 34 a. It has the latching protrusion 34c which protrudes inward from a pair of attachment leg part 34b, respectively. The contact portion 34a is formed with a holding groove 34d for holding the tip portion of the braking action portion 17c. The first mounting recess 17j contacts the groove bottom of the sandwiching groove 34d. The locking projection 34c is locked to the second mounting recess 17k. As a result, the brake shoe 34 is elastically locked to the distal end portion of the braking action portion 17c.

  The brake lever 17 is biased by the spring member 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 by a solid line in FIG.

  The spring member 19 is accommodated in the spring cylinder portion 7 c of the sheet member 7, and is disposed in a compressed state between the mounting portion 17 b and the leg portion 2 b of the reel body 2. The spring member 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 braking lever 17 from the braking state, the rotor 3 enters the braking release state.

  The brake lever 17 is also used to perform an operation of switching the predetermined brake portion 21 between a brake release state shown in FIG. 10A and a predetermined brake state shown in FIG. As described above, an oval locking hole 17i (see FIG. 8) is formed in the braking action portion 17c.

[Configuration of the specified braking part]
As shown in FIGS. 4 and 6, the predetermined braking unit 21 includes a lever member 27 that swings in conjunction with the brake lever 17, a toggle spring 28 that holds the lever member 27 in a braking release position and a predetermined braking position, As shown in FIG. 2, a friction member 29 that is rotatably mounted on the tubular member 40 and frictionally engages with the tubular member 40, and an annular groove 40 d for frictionally engaging the friction member 29 with the tubular member 40. And two friction rings 30 made of, for example, O-rings.

  As shown in FIGS. 3 and 6, the lever member 27 is swingably mounted on a swing shaft 27 a that is screwed and fixed to the rear surface of the mounting member 2 e and is disposed in parallel with the spool shaft 8. The distance from the base end of the 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 lever member 27 is locked in the locking hole 17i, and the lever member 27 is interlocked with the brake lever 17 to release the brake (FIG. 10 (a)) and the predetermined brake position (FIG. 10 (b)). ). A locking claw 70 is swingably attached to the lever member 27. The locking claw 70 has a spring locking portion 70a at the base end and an acute-angle claw portion 70b at the tip, and is attached in the direction in which the claw portion 70b protrudes by the coil spring 71 (counterclockwise in FIG. 6). It is energized. The toggle spring 28 is locked to the base end of the lever member 27.

  Here, the base end of the lever member 27 is urged by the toggle spring 28 when in the braking release position and contacts the upper surface of the locking hole 17i, and contacts the lower surface when in the predetermined braking position. A locking claw 70 is swingably attached to the intermediate portion of the lever member 27. The locking claw 70 has a spring locking portion 70a at the base end and an acute-angle claw portion 70b at the tip, and is attached in the direction in which the claw portion 70b protrudes by the coil spring 71 (counterclockwise in FIG. 5). It is energized. One end of the coil spring 71 is locked to the spring locking portion 70 a and the other end is locked to the swing shaft of the lever member 27. When the locking claw 70 is swingably attached to the lever member 27 and biased in the direction in which the claw portion 70b protrudes by the coil spring 71, the lever member 27 swings to a predetermined braking position. Even if the claw portion 70b and the sawtooth portion 29a of the friction member 29 to be described later are out of phase with each other, even if the claw portion 70b contacts the protruding portion of the sawtooth portion 29a, the shock is absorbed and the friction member 29 is reliably prevented from rotating. it can.

  The friction member 29 is a cylindrical member and is rotatably mounted on the outer periphery of the cylindrical member 40. A serrated portion 29a that engages with the claw portion 70b of the locking claw 70 is formed on the inner peripheral surface of one end (right end in FIG. 4) of the friction member 29 so as to protrude radially inward. The sawtooth portion 29a is provided to engage with the locking claw 70 and prohibit the rotation of the friction member 29 in the yarn unwinding direction when the lever member 27 is in the predetermined braking position (FIG. 10B). . A first washer 72 is disposed between the other end (the left end in FIG. 4) of the friction member 29 and the outer surface of the disc portion 40 c of the cylindrical member 40. The first washer 72 is retained by a retaining ring 74 that is curved in a C shape. The retaining ring 74 is attached to an annular groove 29 c formed on the inner peripheral surface of the other end of the friction member 29. A second washer 75 is mounted between the sawtooth portion 29 a and the tubular member 40. The first washer 72 and the second washer 75 are provided so that the friction member 29 does not rattle by adjusting the axial mounting dimension of the friction member 29.

  In the friction member 29 having such a configuration, when the lever member 27 is disposed at a predetermined braking position and the locking claw 70 is engaged with the sawtooth portion 29 a, the friction member 29 acts on the cylindrical member 40 by the action of the friction ring 30. Friction sliding.

  Here, when the brake lever 17 is pushed into the predetermined braking position, the lever member 27 swings from the braking release position to the predetermined braking position in conjunction therewith. As a result, the locking claw 70 engages with the sawtooth portion 29a 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. 6 and 10, the toggle spring 28 can urge the lever member 27 to urge the brake lever 17 to a predetermined brake position and a brake release position, thereby maintaining the posture. The toggle spring 28 is a torsion coil spring attached to the base end of the lever member 27. One end of the toggle spring 28 is locked to the base end of the lever member 27, and the other end is locked to the front end surface of the reel body 2a. As shown in FIG. 10A, the toggle spring 28 urges the lever member 27 in the clockwise direction of FIG. 6A when the lever member 27 is arranged at the brake release position, and is arranged at the predetermined braking position. Then, it is urged counterclockwise in FIG. As a result, the lever member 27 is held at the brake release position and the predetermined brake position, and the brake lever 17 is further held at the brake release position and the predetermined brake position.

<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, when the handle assembly 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 assembly 1 is transmitted to the pinion gear 12 via the master gear 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 12. At this time, since the rotor 3 rotates in the yarn winding direction, the ratchet pawl 43 of the one-way clutch 32 is biased to the meshing release position side by the biasing member 44, and the meshing between the ratchet pawl 43 and the ratchet wheel 42 is released. The rotational force is not transmitted to the tubular member 40. 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 action of the spring member 19 and the predetermined brake portion 21 and is disposed at the brake release position or the predetermined brake position.

  When exchanging with the fish by reversing the rotor 3, the pulling operation portion 17d of the brake lever 17 is pulled toward the rod mounting portion 2c side with, for example, an index finger to adjust the braking force.

  When the fishing line is pulled by the fish and the rotor 3 is reversed in the line-feeding direction, the rotational force of the rotor 3 is transmitted to the tubular member 40 via the one-way clutch 32, and further transmitted to the brake cylinder 41 via the one-way clutch 32. The brake mechanism 6 is ready for braking. When the rotor 3 rotates in the yarn feeding direction, in the one-way clutch 32, the ratchet pawl 43 is urged by the urging member 44 and swings toward the meshing position. When the ratchet pawl 43 swings to the meshing position, the ratchet teeth 42b of the ratchet wheel 42 collide with the pawl portion 43a at the tip of the ratchet pawl 43, and the ratchet wheel 42 vibrates. However, this vibration is absorbed by the vibration isolation member 45 and is not transmitted to the rotor 3. For this reason, it becomes difficult to give discomfort to the angler, and it is difficult to adversely affect the ratchet teeth 42b and the ratchet pawl 43.

  When the ratchet teeth 42 b mesh with the ratchet pawl 43, the rotation of the rotor 3 is transmitted to the tubular member 40, and the brake cylinder 41 rotates integrally with the rotor 3. When the pulling operation portion 17d of the brake lever 17 is pulled in a direction approaching the rod mounting portion 2c, the lever member 27 swings to the brake release position side even if the brake lever 17 is at the predetermined braking position. 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 lever member 27, the lever member 27 is biased toward the brake release position, and the lever member 27 is held at the brake release position (FIG. 10A).

  In this state, when the brake lever 17 is further operated in a direction approaching the rod 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. At this time, since the rear part of the locking hole 17i is wider than the front part, interference with the lever member 27 is less likely to occur, the braking operation by the braking lever 17 is not affected, and a strong braking force can be obtained. it can.

  When the fishing ground is moved or the reel is stored, the hand is released from the pull-in operation portion 17d, and the first push-in operation portion 17e or the second push-in operation portion 17f is pushed away from the rod mounting portion 2c. Then, as shown in FIGS. 4 and 10B, the lever member 27 swings from the brake release position to the predetermined brake position and is held at that position by the toggle spring 28. As a result, the engaging claw 70 engages with the sawtooth portion 29a of the friction member 29 to prevent the rotation of the friction member 29, and the reverse rotation of the rotor 3 is prevented.

  The braking force at this time is determined by the elastic force of the friction ring 30 mounted between the friction member 29 and the cylindrical member 40. For this reason, even if something hits the handle assembly 1 during the movement, it becomes easy to obtain a predetermined braking force that is strong enough to prevent the handle assembly 1 from turning, and the predetermined braking force is strong enough that no dandruff occurs during the movement of the fishing ground. Power can be set. In addition, 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 heel mounting part 2c slightly. Then, as described above, the lever member 27 is swung to the brake release position by the brake lever 17 and the predetermined brake state is once released.
