[0001] cross-reference This application claims priority based on Japanese Patent Application 2023-194186 (filed on November 15, 2023), the contents of which are incorporated herein by reference in their entirety. This invention relates to braking devices and fishing reels. Background Technology
[0002] In the past, fishing reels used different components to adjust eddy current braking units that changed braking force according to the rotation of the reel and friction braking units that hardly depended on the rotation of the reel, as a unit to prevent line tangling.
[0003] For example, Patent Document 1 discloses a fishing reel comprising a reel body having: a frame having left and right side frames; a handle disposed on one of the left and right side frames of the frame; side plates disposed on the left and right side frames of the frame respectively; and a spool rotatably supported between the side plates. A braking device for adjusting the rotational braking force of the spool is disposed between the side frame and the side plate on the opposite side of the handle. The braking device has: multiple operating parts operated by the angler to adjust the rotational braking force of the spool; and multiple visual recognition parts for the angler to visually recognize the adjustment state of the operating parts. The side plate on the opposite side of the handle has a window on its outer surface, through which the angler holding the reel body can visually recognize the multiple visual recognition parts from the outside of the side plate. The visual recognition parts and the operating parts exposed in the window are arranged in a non-protruding state relative to the outer surface of the side plate.
[0004] Patent documents Patent Document 1: Japanese Patent Application Publication No. 2012-147740 Summary of the Invention
[0005] Typically, in order to increase flight distance and prevent recoil, the braking unit aims to provide optimal braking force over a wide speed range. However, as a situation where the drum needs to be braked, it is considered particularly important to apply greater braking force immediately after throwing to prevent recoil, at maximum speed, at low speeds before landing to extend flight distance, and at landing when greater braking force is desired.
[0006] However, in any fishing reel, including the one described in Patent Document 1, it is impossible to increase the flight distance and prevent recoil in all the aforementioned situations. In most cases, when a greater braking force is desired when landing in the water, the angler must perform thumb control of the line during the landing. Furthermore, it is difficult to grasp the optimal timing when fishing at night or when watching for lost lures. Therefore, the existing known methods have the following problems: it is difficult to accurately and reliably increase the flight distance and prevent recoil by providing optimal braking force over a wide speed range.
[0007] The present invention was made in view of the above circumstances, and the technical problem to be solved is to provide a braking device and fishing reel that not only achieves miniaturization and low cost, but also provides optimal braking force over a wider speed range, thereby more effectively increasing flight distance and preventing recoil.

Detailed Implementation
[0018] The embodiments of the braking device and fishing reel according to the present invention will now be described in detail with reference to the accompanying drawings. In the various drawings, common components are labeled with the same reference numerals. For ease of explanation, the drawings are not necessarily described to an exact scale; this should be noted.
[0019] The fishing reel of this invention is of the type known as a double-bearing reel. First, a brief explanation will be given of the structure of general double-bearing reels, including the fishing reel of this invention, the causes of recoil, and methods to prevent it.
[0020] In this dual-bearing reel, a spool for winding fishing line is rotatably supported on the reel body (frame). The user can operate the spool in the forward (rewinding direction) direction using a conventional operating unit such as a handle, thereby winding the fishing line onto the spool. The dual-bearing reel has a conventional clutch (not shown) that, in the engaged state, transmits driving force from the operating unit to the spool 2. On the other hand, in the unengaged state, the spool becomes freely rotatable, and in this state, by applying external force to the fishing line, the spool can be rotated in the release direction.
[0021] At this point, when the rotational speed of the reel exceeds the release speed of the lure or other projectile, slack line will be generated. As the amount of slack line increases, tangling (recoil) will occur. To prevent tangling (recoil), a braking device can be used to apply braking force to the reel. However, if the braking force is too large, the throwing distance will be reduced. On the other hand, if the braking force is too small, the risk of tangling (recoil) will increase.
[0022] Next, refer to Figure 1 A braking device according to one embodiment of the present invention and a braking device included in a fishing reel will be described.
[0023] like Figure 1 As shown, the braking device 7 and fishing reel 1 according to one embodiment of the present invention include: an electromagnetic braking part (electromagnetic braking unit) 71, which applies electromagnetic braking force to the reel 2; and a friction braking part (friction braking unit) 72, which contacts the reel 2 and applies braking force caused by friction.
[0024] The electromagnetic braking unit 71, commonly referred to as an eddy current brake, consists of an induction rotor (the braked component) 21 made of a conductive material such as aluminum, integrally formed with the drum 2, and a permanent magnet 711 mounted on the winding body. When the drum 2 rotates, eddy currents are generated on the induction rotor 21 by the magnetic field generated by the permanent magnet 711. As a result, a braking torque proportional to the rotational speed and the magnetic field strength on the induction rotor is generated on the drum 2.
[0025] The friction braking unit 72 consists of a friction-bearing component 22 disposed on the drum 2, a contact component 721 in contact with the friction-bearing component 22, and an elastic component 722 that applies force to the contact component 721. A frictional force (Coulomb friction) proportional to the force applied by the elastic component 721 is generated on the friction-bearing component 22. Therefore, a braking torque independent of the rotational speed is generated on the drum 2.
[0026] The adjusting member 73 can simultaneously adjust the braking torque of both the electromagnetic braking unit 71 and the friction braking unit 72. In the braking device 7 and fishing reel 1 according to one embodiment of the present invention, the adjusting member 73 is supported so that it can rotate within a certain range (e.g., 0° to 180°) relative to the reel body 3. Moreover, according to the rotation of the adjusting member 73, the strength of the magnetic field acting on the induction rotor 21 changes by moving the permanent magnet 711 of the electromagnetic braking unit 71. At the same time, according to the rotation of the adjusting member 73, the deformation of the elastic member also changes by a predetermined mechanism 723. Thus, according to the rotation of the adjusting member 73, the braking torque of both the electromagnetic braking unit 71 and the friction braking unit 72 can be adjusted.
[0027] At this point, it can be configured such that when the electromagnetic braking unit 71 generates maximum braking torque, the friction braking unit 72 also generates maximum braking torque. Furthermore, it can be configured such that when the electromagnetic braking unit 71 generates minimum braking torque, the contact member 721 does not contact the rubbed member 21.
[0028] Next, refer to Figure 2 The characteristics of the braking torque and drum speed of the electromagnetic braking unit were analyzed separately. Figure 2 (A) Characteristics of braking torque and drum speed of friction braking unit ( Figure 2 (B) Characteristics of the braking torque and drum speed of the braking device of the present invention ( Figure 2 (C) will be explained. Additionally, refer to... Figure 8 The relationship between the braking torque of the electromagnetic braking unit and the position θ of the adjusting component is discussed separately. Figure 8 (A) The relationship between the position θ of the braking torque adjustment component of the friction braking unit ( Figure 8 (B) The relationship between the position θ of the braking torque adjustment component of the braking device ( Figure 8 (C) will be explained.
[0029] The braking torque generated by the electromagnetic braking unit 71 is proportional to the drum speed and the magnetic field strength generated on the induction rotor 21. When the magnetic field strength is configured to be proportional to the position of the adjusting member 73, the braking torque on the drum 2 has the following characteristics: Figure 2 (A) Characteristics. The braking torque generated by the friction braking unit is independent of the drum speed and produces a braking force and torque proportional to the vertical resistance generated on the friction component 21. Therefore, the braking torque generated by the friction braking unit 72 has the following characteristics: Figure 2(B) Characteristics. Furthermore, when the contact member 721 is not in contact with the rubbed member 22, the braking torque generated by the friction braking unit is 0. Utilizing this, it can be configured such that when the position θ of the contact member 721 in contact with the rubbed member 22 is θ1°, if the position θ of the adjusting member is less than θ1°, the contact member 721 becomes non-contact, and as it becomes the same as or greater than θ1°, the force applied by the elastic member 722 increases. Thus, it can be configured as follows: Figure 8 (B) characteristics.
[0030] Will Figure 2 (A) shows the braking torque generated by the electromagnetic braking unit and Figure 2 (B) shows the combined braking torque generated by the friction braking unit. Figure 2 (C) describes the braking torque characteristics of the braking device 7 included in the braking device 7 and the fishing reel 1 according to one embodiment of the present invention. Thus, by changing the position of the adjusting member, the characteristics of the braking torque can be significantly altered.
[0031] The effects of the braking device 7 according to one embodiment of the present invention and the braking device 7 included in the fishing reel 1 will be explained. In the braking device 7 included in the braking device 7 according to one embodiment of the present invention and the fishing reel 1, for the drum 2, both braking torque generated by non-contact force, i.e., eddy current and braking torque generated by contact force, i.e., friction, can be generated, and the amount can be adjusted by an adjustment member 73, thus enabling the braking unit to have the advantage of having both braking torques.
[0032] Here, since the braking torque generated by eddy currents is a non-contact force, the effects of wear can be avoided. Furthermore, since it is independent of the surface friction coefficient, it has the advantage of avoiding the effects of wetting. On the other hand, since the braking torque decreases at low speeds, there is a disadvantage that the required braking torque cannot be obtained when recoil occurs at low speeds. Since the braking torque generated by contact friction can be considered as Coulomb friction, a roughly constant braking torque can be generated at both low and high speeds, thus providing the required braking torque even when recoil occurs at low speeds.
[0033] According to one embodiment of the present invention, the braking device 7 and the braking device 7 included in the fishing reel 1 can ensure the required braking force and torque mainly by means of the friction braking unit when the drum speed is low. Furthermore, when the drum speed is high, the required braking force and torque can be ensured mainly by means of the electromagnetic braking unit. Therefore, the required braking force and torque can be ensured over a wide range of drum speeds. Moreover, since the required braking torque can be generated by both the friction braking unit and the electromagnetic braking unit, the torque capacity required by each braking unit can be reduced compared to a case where each unit is configured individually. This enables miniaturization, extended lifespan, and reduced cost of each braking unit.
[0034] When only the electromagnetic braking unit is operating, the braking force is directly proportional to the product of the drum's speed and the magnetic force acting on the inductive rotor. Therefore, as... Figure 8 As shown, at low drum speeds, regardless of the position θ of the adjusting member, a large braking force cannot be applied. On the other hand, in braking devices 7 as described in one embodiment of the present invention and the braking device 7 included in the fishing reel 1, when both the electromagnetic braking unit and the friction braking unit operate, sufficient braking torque can be generated by the friction braking unit even at low drum speeds. Furthermore, by adjusting the position of the adjusting member, the braking torque can be reduced when no braking torque is needed, thereby extending the flight distance of projectiles such as lures.
[0035] Furthermore, compared to generating the required braking torque solely through friction braking, this method offers advantages such as ease of avoiding wear and less reliance on the surface friction coefficient. If, as in the braking device 7 of one embodiment of the present invention and the braking device 7 included in the fishing reel 1, the braking torque of both braking devices can be adjusted by a single adjustment member, then independent adjustment of each braking device is unnecessary. Therefore, when used as a casting brake for a fishing reel, the disadvantage of not being able to control it independently is virtually eliminated.
[0036] This is because, when braking torque is required, both the friction braking unit and the electromagnetic braking unit can simultaneously increase the braking torque, and when braking torque is not required, both the friction braking unit and the electromagnetic braking unit can simultaneously decrease the braking torque. On the other hand, by using one adjusting component to adjust the two braking torques, only one adjusting component is needed, thus enabling the overall miniaturization and cost reduction of the device.
[0037] like Figure 1As shown, the braking device 7 and the fishing reel 1 according to one embodiment of the present invention can further be position-controlled by a motor 9. Furthermore, it may also include a motor 9 for driving the adjustment member and a control unit (microcomputer) 11 for controlling the motor 9. In this case, a speed reduction mechanism may be provided between the motor and the adjustment member as needed. Additionally, a sensor for detecting the position of the adjustment member can be provided so that the position of the adjustment member can be accurately positioned sequentially through feedback control or the like.
[0038] Therefore, even midway through the casting process, the braking torque characteristics of the braking device can be adjusted. By setting up a detection unit (detection unit) to detect the speed of the reel and the amount of slack line generated, and a motion sensor to detect the user's rod operation, and adjusting the braking torque based on the detected values, optimization of the braking torque can be easily achieved. In this case, such as Figure 2 (C) and Figure 8 As shown in (C), the braking device 7 according to an embodiment of the present invention and the braking device 7 included in the fishing reel 1 can widen the settable range of braking torque by adjusting the position of the adjusting member. In this way, the braking torque can be optimized under various conditions.
[0039] Furthermore, as with the braking device 7 of one embodiment of the present invention and the braking device 7 of the fishing reel 1, by adjusting two braking torques with one adjusting member, only one motor or motor driver is required, thus enabling miniaturization and cost reduction of the entire device. In addition, the control program can be simplified.
[0040] Next, refer to Figure 3 A specific example of throwing objects such as lures using the braking device 7 according to an embodiment of the present invention and the braking device 7 of the fishing reel 1 will be described. Figure 3 The graph shows the change in drum speed over time when throwing objects such as lures. The vertical axis represents the drum speed, and the horizontal axis represents time.
[0041] Here, the process from casting the lure to its landing in the water is divided into four regions: (1) the acceleration region, (2) the maximum speed region, (3) the cruising region, and (4) the landing region. First, in the (1) acceleration region, when the user swings the fishing rod, the cast object (e.g., the lure) is subjected to tension from the fishing line and given an initial velocity. Subsequently, when the user allows the reel to rotate freely at an appropriate time, the reel is subjected to tension from the fishing line and begins to rotate. During the period when the amount of fishing line released from the reel does not exceed the speed of the lure, the reel is continuously subjected to tension from the fishing line and continues to accelerate. During this period, the lure gradually changes its trajectory due to the tension from the fishing line. The acceleration region is mostly from the start of casting (throwing) until 80 to 150 ms have elapsed. Furthermore, in the acceleration region, since the reel is always subjected to tension from the lure, no excess line is generated, and there is no need to generate a large braking torque on the braking device.
[0042] Next, in the (2) highest speed region, the reel continues to be under tension by the fishing line, and soon the lure's flight speed and the line's release speed reach equilibrium. At this moment, the reel reaches its highest speed. In the case of a typical double-bearing reel, the highest speed of the reel is usually around 10,000 to 40,000 rpm, depending on the conditions. When no braking torque is applied to the reel, the tension of the fishing line is zero. After casting, the lure continues to decelerate due to air resistance, while the reel continues to reach its highest speed due to inertia. As a result, the release speed of the fishing line will exceed the lure's flight speed, resulting in slack or recoil. Since the reel's speed is at its highest speed, the recoil generated at this moment tends to increase dramatically. To prevent this, a braking torque is applied to the reel by a braking device.
[0043] Preferably, the braking torque is equal to the air resistance experienced by the lure or fishing line multiplied by the drum radius. Since the greater the flight speed, the greater the air resistance experienced by the lure, the required braking torque also increases with the lure's flight speed. Furthermore, the required braking torque is easily influenced by various factors such as the lure's attitude, trajectory, weight, shape, rod swing and characteristics, and wind conditions. In the braking device 7 and fishing reel 1 according to one embodiment of the present invention, the braking torque generated in this case is primarily produced by an electromagnetic braking unit. Therefore, even if the lure's flight speed changes, the braking torque changes accordingly, making it easy to optimize the braking torque using the same set component positions.
[0044] Next, in the cruising zone (3), after reaching maximum speed, the lure continues to be cast at an angle while being subjected to air resistance and gravity, and the reel continues to decelerate through the braking device. When the braking torque is too large, the lure experiences tension backward from the fishing line, thus shortening the casting distance. When the braking torque is too small, the speed at which the fishing line is released from the reel exceeds the lure's flight speed, resulting in slack or recoil. Therefore, the braking torque in this case is preferably equal to the air resistance experienced by the lure or fishing line. Since the greater the flight speed, the greater the air resistance experienced by the lure, the required braking torque also increases according to the lure's flight speed. Therefore, in the cruising zone, it is also preferable to generate the braking torque mainly by the electromagnetic braking unit.
[0045] Next, in the area of (4) when the lure hits the water, it experiences significant resistance from the water or ground, causing it to decelerate rapidly. When using a typical reel, it often hits the water about 1-4 seconds after casting, at which point the reel speed is typically around 2000-5000 rpm, and the reel continues to rotate due to inertia. Therefore, if the reel is not braked, excess line or backlash will occur. In the braking device 7 and the fishing reel 1 according to one embodiment of the present invention, braking torque can be generated primarily by a friction braking unit. Thus, even when the reel speed decreases to low, such as when it hits the water, sufficient braking torque can be obtained.
[0046] Existing braking mechanisms require the user to visually observe the water impact and apply braking with their fingers (thumb-controlled line operation) or pre-apply a large braking torque. When the user uses thumb-controlled line operation, depending on their skill level, there are issues such as reduced flight distance or recoil. Especially at night, in inclement weather, or during long-distance lure casting, it may be difficult to visually observe the water impact, making it challenging to optimize the braking torque. Furthermore, if a braking torque sufficient to prevent recoil upon water impact is required, a large braking torque is needed throughout the casting process, potentially reducing flight distance.
[0047] Conversely, in the braking device 7 and fishing reel 1 according to one embodiment of the present invention, when the speed of the reel is detected to be below a predetermined value and water is detected, the position of the adjusting member can be adjusted to generate a larger braking torque. Therefore, even without thumb-operated line control during water entry, recoil during water entry can be effectively suppressed. Thus, since the braking device 7 and fishing reel 1 according to one embodiment of the present invention can adjust the braking torque of both the electromagnetic braking unit and the friction braking unit using a single adjusting member, the braking torque can be optimized according to various conditions.
[0048] Furthermore, by configuring the adjustment member on the braking device 7, which is part of one embodiment of the present invention, and the braking device 7 of the fishing reel 1 to be adjusted by a motor, the required braking torque can be generated at any time, even in the middle of throwing (casting), so that the extension of flight distance and the prevention of recoil can be achieved simultaneously over a wide range.
[0049] Next, refer to Figure 4 and Figure 5 The diagram shows a specific configuration example of the braking device 7 included in a fishing reel 1 according to an embodiment of the present invention. Figure 4 An exploded perspective view of the braking device 7 according to an embodiment of the present invention and the braking device 7 included in the fishing reel 1 is shown. Figure 5 This is a cross-sectional view of the brake device 7 as assembled, taken through a plane passing through the rotation axis of the reel, on the brake device 7 and the fishing reel 1 according to one embodiment of the present invention. Figure 5 (A) represents the state with the greatest braking force. Figure 5 (B) represents the state with the minimum braking force.
[0050] A fishing reel 1 equipped with the braking device 7 according to one embodiment of the present invention is configured to include a reel 2, a fixing member (mounting plate) 8, an electromagnetic braking unit 71, an induction rotor 21, a fixed magnet 711A, a rotating magnet 711B, a magnetic gear 73, a friction braking part 72, a contact member 721, a straight-moving member 723, a force-applying spring 722, a guide rod 724, a cover 81, and a motor 9.
[0051] The spool 2 is generally cylindrical and can wind fishing line around its outer periphery. It is rotatably supported by a pivot on a fixed member 8. An induction rotor 21 (described later) is fixed to its end face and has a friction braking surface 22. The friction braking surface 22 is preferably made of a material with wear resistance, a high coefficient of friction, and minimal variation in the coefficient of friction; preferably, it is made of felt or carbon fiber infiltrated with grease, metal, resin, etc. The fixed member 8 and the cover 81 are structural components fixed to the reel body 3. By arranging a magnetic gear 73 and a straight-moving member 723 between the fixed member 8 and the cover 81, the magnetic gear 73 can be rotated, and the straight-moving member 723 can be translationally held in place.
[0052] The induction rotor 21 is generally cylindrical and made of a non-ferrous metal such as aluminum or copper. The fixed magnet 711A is cylindrical and fixed to the fixing member 8. It is divided into N equal parts (e.g., 6 equal parts) circumferentially and is alternately magnetized as N and S poles. The fixed magnet 711A is coaxially disposed inside the induction rotor 21 through a predetermined gap. The rotating magnet 711B is cylindrical, fixed to the magnet gear 73, divided into N equal parts (e.g., 6 equal parts) circumferentially, and is alternately magnetized as N and S poles. The rotating magnet 711B is coaxially disposed outside the induction rotor 21 through a predetermined gap.
[0053] The magnetic gear 73 is rotatably supported on the fixed member 8 by a shaft. The magnetic gear 73 corresponds to an adjustment member on a fishing reel 1 equipped with a braking device 7 according to one embodiment of the present invention. Figure 5 As shown in (A), the magnetic field strength through the induction rotor 21 is greatest when the rotating magnet 711A and the fixed magnet 711B are facing each other with opposite poles. Furthermore, as... Figure 5 As shown in (B), when the position of the magnet gear 73 is adjusted so that the rotating magnet 711A and the fixed magnet 711B are opposite each other with the same poles, the strength of the magnetic field penetrating the induction rotor 21 is minimized.
[0054] The magnetic gear 73 can be driven to rotate by a motor (not shown). By using a known unit to control the position of the motor, the intensity of the eddy current brake acting on the induction rotor 21 can be adjusted. Alternatively, the user can directly adjust the position of the magnetic gear 73 using an operating unit such as a dial.
[0055] The straight-moving member 723 is supported so that it can move axially relative to the fixed member by guiding the guide rod 724, which is held on the fixed member 8, into the guide hole 7233. Furthermore, the straight-moving member 723 has a helical cam 7231 disposed on its side (in... Figure 4In the example shown, there are three such locations at 120° intervals. The helical cam 7231 follows the follower 731 disposed on the outer periphery of the magnetic gear 73. Thus, it can translate axially according to the rotation of the magnetic gear 73. The straight-moving member 723 has a contact member holding portion 7232 (in... Figure 4 In the example shown, there are 3 locations at 120° intervals. The force-applying spring 722 and the contact member 721 can be accommodated inside the contact member holding part 7232.
[0056] like Figure 5 As shown in (A), when the straight-moving member 723 is axially forward, the contact member 721 contacts the friction braking surface 22 provided on the end face of the drum, and the deformation of the force-applying spring 722 is at its maximum. Therefore, the contact member 721 imparts the maximum braking force to the drum 2. When the straight-moving member 723 is gradually moved rearward from this state, the deformation of the force-applying spring 722 gradually decreases, and the braking force also decreases accordingly. Figure 5 As shown in (B), when the straight-moving component 723 is moved further backward, the contact component 721 leaves the friction braking surface 22 and the braking force is zero.
[0057] Depending on the position of the magnetic gear 73, both the braking force generated by the eddy current brake and the braking force generated by friction can be adjusted. That is, the magnetic gear 73 acts as a position adjustment component, enabling the aforementioned effect. Furthermore, the adjustment methods for the adjustment component and the electromagnetic braking unit, as well as the adjustment methods for the adjustment component and the friction brake, are not limited to the examples of this embodiment.
[0058] Figure 6 Other adjustment methods for the electromagnetic braking unit are shown. In this example, the width of the axial gap between one pole of the permanent magnet 712 and the drum 2 is adjusted by a pinion (not shown) provided on the adjustment member 173 and a rack (not shown) provided on the permanent magnet 712. Thus, since the strength of the magnetic field on the drum can be adjusted, the electromagnetic braking force can be adjusted. Furthermore, the motor 9 and the control unit (microcomputer) 11 are as described above, and their description is omitted here.
[0059] Next, refer to Figure 7 Other adjustment methods of the friction braking part (friction braking unit) of the braking device 7 included in the braking device 7 of the fishing reel 1 according to one embodiment of the present invention will be described. Figure 7 This is a cross-sectional view of the friction brake section, viewed from a plane orthogonal to the axis of rotation of the drum. Figure 7 (A) represents the state of minimum braking force. Figure 7 (b) indicates the state of maximum braking force.
[0060] In one embodiment of the present invention, the braking device 7 and the other adjustment method of the friction braking part (friction braking unit) of the braking device 7 included in the fishing reel 1, the contact member (elastic deformation part) 1721 is configured as an elastically deformable cantilever beam. One end of the contact member 1721 (cantilever beam) is connected to a rotating shaft 1621, which is connected by gears or the like (not shown) to rotate in conjunction with the rotation of the adjustment member 1073. Furthermore, the other end of the contact member 1721 (cantilever beam) can contact a friction braking member 1521 provided on a part of a reel (not shown).
[0061] When the position of the adjusting component 1073 is adjusted to the minimum braking state, then as follows: Figure 7 As shown in (A), the contact member 1721 moves to a position where it does not contact the friction braking member 1521. On the other hand, when the position of the adjusting member 1073 is adjusted to the maximum braking state, then as shown in (A), the contact member 1721 moves to a position where it does not contact the friction braking member 1521. Figure 7 As shown in (B), the contact component 1721 contacts the friction braking component 1521, and the elastic deformation of the cantilever beam is at its maximum. Thus, the friction braking torque is generated on the friction braking component 1521.
[0062] In other adjustment methods of the friction braking portion (friction braking unit) of the braking device 7 and the fishing reel 1 according to one embodiment of the present invention, a mechanism that generates contact force in the radial direction of the drum (not shown) may also be used. In this case, as in other adjustment methods of the friction braking portion (friction braking unit) of the braking device 7 and the fishing reel 1 according to one embodiment of the present invention, by arranging a plurality of contact members 1721 at equal intervals in the circumferential direction as much as possible, braking force can be generated evenly without generating excessive load on the rotating shaft.
[0063] Therefore, the adjustment method of the electromagnetic braking part (electromagnetic braking unit) of the braking device 7 and the fishing reel 1 according to one embodiment of the present invention can also be implemented by other methods, such as using a mechanism that moves a portion of a permanent magnet. Furthermore, the adjustment method of the friction braking part (friction braking unit) of the braking device 7 and the fishing reel 1 according to one embodiment of the present invention can also be implemented by other methods, such as using a mechanism that adjusts the vertical resistance acting on the reel. The method of adjusting both the electromagnetic braking part and the friction braking part using a single adjustment member can be achieved by a combination of the above-described mechanisms.
