Fishing reel with line cup rotation control mechanism

Abstract

Disclosed is a fishing reel having a spool rotation control mechanism. The fishing reel includes a spool, a reel frame that freely holds the spool, and a rotation control mechanism that controls the spool. The rotation control mechanism includes an electromagnetic brake structure that generates a braking force and a braking force adjustment mechanism that adjusts the braking force. The braking force adjustment mechanism includes a cam shaft, a moving member that has a cam shaft contact end portion that can contact the cam shaft, and a force applying member that applies a force to the moving member. The cam shaft contact end portion is an open structure to the outside, and has a partition wall that has a shape determined by a line that is inclined with respect to the axis of the spool shaft. The cam shaft contacts the cam shaft contact end portion in a manner that is restrained by only the partition wall. In the fishing reel of the present invention, since the cam shaft contacts only the partition wall, the moving member can be moved with a small force, and after bait or the like is cast, the moving member can be quickly returned to the initial position with a small force.

Description

Technical Field

[0001] This invention relates to a fishing reel equipped with a spool rotation control mechanism. More specifically, it relates to a fishing reel equipped with a mechanism for controlling the rotation of the spool using electromagnetic braking. Background Technology

[0002] Fishing reels include spinning reels, double-bearing reels, and single-bearing reels. In spinning reels, the spool is movable back and forth on the reel body. In double-bearing and single-bearing reels, the spool is freely rotatably supported on the reel body. With this structure, double-bearing and single-bearing reels can directly bear the force applied to the line through the spool, and are thus used as baiting reels for releasing weighted lures or devices (hereinafter referred to as lures, etc.).

[0003] On the other hand, double-bearing and single-bearing fishing reels have the following problems: due to the fact that the force applied to the line is directly borne by the fishing reel, the line is prone to tangling with the spool during casting (i.e., the so-called back ash).

[0004] In other words, when bait is cast, it travels in a parabolic trajectory, and the fishing line attached to it is pulled and released from the spool. Initially after the bait is released, the spool rotates relatively slowly, but then its rotation speed increases to keep up with the bait's flight speed. Once the bait has passed the apex of its parabola, its flight speed decreases due to air resistance, while the spool continues to rotate due to the law of inertia, without a significant decrease in rotation speed. Furthermore, once the bait touches the water, although the pulling force of the bait on the fishing line becomes zero, the spool continues to rotate even as its rotation speed decreases.

[0005] As a result, the amount of fishing line supplied from the spool is more than the amount of fishing line pulled by the bait, etc., thus producing what is called backlash.

[0006] Generally, the way to prevent this backlash is to press the spool with your thumb during casting to create frictional braking (i.e., line stopping). However, this line stopping technique cannot be performed properly unless you are a skilled angler, so a fishing reel that can prevent backlash is needed even for anglers who are not used to using baitcasting reels.

[0007] To address this need, baitcasting reels with various mechanisms to prevent recoil have been developed. One such baitcasting reel (e.g., Patent Documents 1 and 2) is proposed that generates a braking force against spool rotation through the magnetic force between a magnetic body and a dielectric body, and adjusts this braking force according to the spool rotation speed, thereby suppressing the reduction of the flight distance of bait and preventing recoil.

[0011] Patent Document 2: Japanese Invention Patent No. 6376572 Summary of the Invention

[0012] The problem that the invention aims to solve

[0013] However, existing bait-type reels with such anti-recoil mechanisms need improvement in several aspects.

[0014] First, in any fishing reel, such as Figure 1 As shown in (a) and (b), the cam mechanism used to adjust the distance between the magnet and the dielectric body according to the rotation speed of the spool has a structure in which the cam shaft 32 engages with the cam groove 31, which is closed from the outside through the partition. Therefore, when the cam shaft 32 moves, the cam shaft 32 is subjected to frictional resistance from the two partitions. The movement of the cam shaft 32 requires a large force, and there is a problem that the cam shaft 32 is delayed in returning to the initial position after being thrown.

[0015] Furthermore, in cam mechanisms with such cam grooves 31, when fishing reels are used in the field, foreign objects such as sand can easily enter the cam grooves 31 and remain there, which cannot be completely removed even when washed with water. Therefore, the residual sand and other foreign objects can cause the fishing reel to malfunction and sometimes become the cause of failure.

[0016] In addition, the presence of metal material around the cam groove 31 in order to form the cam groove hinders the lightweighting of the moving component that moves via the cam mechanism, which is the main reason why the camshaft 32 requires a large force to move, and is also one of the reasons that hinders the lightweighting of the fishing reel.

[0017] Furthermore, in the fishing reel of Patent Document 1, since the cam groove 31 is asymmetrical relative to the spool shaft, different cam mechanisms need to be manufactured for fishing reels where the rocker arm assembly is set on the right and left sides of the reel body.

[0018] The purpose of this invention is to solve the problems existing in existing baitcasting fishing reels equipped with such anti-recoil mechanisms.

[0019] Methods for solving problems

[0020] As a means to solve the above problems, in one embodiment of the present invention, a baiting fishing reel is provided, comprising:

[0021] A spool, the spool having a spool shaft, a sleeve and a winding body, the sleeve covering at least a portion of the spool shaft and fixed to the spool shaft as appropriate, the winding body being connected to the spool shaft or the sleeve;

[0022] The fishing reel holder rotates freely to hold the spool.

[0023] A rotation control mechanism can control the rotation of the spool;

[0024] The rotation control mechanism includes: an electromagnetic braking structure that generates a braking force to resist the rotation of the spool and a braking force adjustment mechanism that adjusts the braking force.

[0025] The electromagnetic braking structure has a pair of magnetic bodies and conductive components. One of the magnetic bodies and the conductive components is disposed in the braking force adjustment mechanism, and the other is disposed in the fishing reel frame and can be accessed through the braking force adjustment mechanism.

[0026] The braking force adjustment mechanism includes:

[0027] A camshaft protrudes in a direction substantially perpendicular to the axial direction of the spool shaft and is disposed on the spool shaft or the sleeve.

[0028] The movable component is a cylindrical component with a circular cross-section that can rotate coaxially with the spool shaft within a certain range and move along the axial direction of the spool shaft. The movable component has a camshaft contact end that can engage with the camshaft.

[0029] The force-applying component applies force to the moving component from one end side along the direction of the spool axis;

[0030] The moving member is connected to the magnetic body or the conductive member at or near its end on the side opposite to the contact end of the camshaft. The contact end of the camshaft has a shape defined by a line inclined relative to the axis of the spool shaft on the side opposite to the magnetic body or the conductive member. Preferably, it has a shape defined by a line that takes the position corresponding to the axis of the spool shaft as its vertex, and is inclined vertically away from the vertex towards the side opposite to the magnetic body or the conductive member, relative to the axis of the spool shaft, and is linearly symmetrical with respect to the spool shaft.

[0031] The force-applying member applies force to the moving member from the side of the magnetic body or the conductive member. The camshaft engages with the contact end of the camshaft, and the moving member, which is fixed with the magnetic body or the conductive member, moves axially along the spool shaft according to the difference between the rotational speed of the spool and the rotational speed of the moving member, thereby controlling the spacing between the paired magnetic bodies and the conductive members.

[0032] In a preferred embodiment, a stop position defining member is provided. This stop position defining member is located on the side of the force-applying member opposite to the moving member side, adjacent to the force-applying member directly or via another member, and is fixed to the spool shaft or the sleeve, thereby positioning and maintaining the force-applying member. The stop position defining member is preferably an annular member of a predetermined thickness having a generally circular through hole in the center through which the spool shaft or a spool shaft with a sleeve can pass. The stop position defining member has a plurality of through holes or bottomed holes of different depths at predetermined intervals in the circumferential direction; the plurality of holes are open in a manner communicating with the central through hole of the stop position defining member. On the other hand, a positioning protrusion is provided on the spool shaft or the sleeve. This positioning protrusion protrudes approximately perpendicularly to the axial direction of the spool shaft near the end of the force-applying member on the side opposite to the moving member side, and engages with any one of the plurality of holes of the stop position defining member. In a particularly preferred embodiment, among the plurality of holes, the holes located opposite each other at the center of the generally circular through hole through which the spool shaft can pass have approximately the same depth; on the other hand, the spool shaft or the sleeve is provided with a pair of positioning protrusions, which protrude in a generally perpendicular opposite direction relative to the axial direction of the spool shaft near the end of the force-applying member on the side opposite to the moving member side, and these pair of protrusions engage with any pair of holes of approximately the same depth among the plurality of holes of the stop position defining member.

[0033] The effects of the invention

[0034] In the fishing reel of the present invention, the cam mechanism includes a camshaft and a camshaft contact end of the shape described above. This camshaft contact end is essentially a structure that removes approximately half of the partition used to form the cam groove, so that the camshaft contacts only one partition and, depending on the situation, is temporarily in a non-contact state with the partition, thus avoiding frictional resistance from both partitions. Therefore, it can be moved with relatively small force, and after casting bait, it can be quickly returned to its initial position with relatively small force.

[0035] In addition, since the contact end of the camshaft is an open structure, even if foreign objects such as sand enter the cam groove 31, they can be easily cleaned by washing with water, and the cam mechanism can be easily cleaned and lubricated.

[0036] In addition, the absence of a large amount of metal material around the cam groove allows for the lightweighting of moving components, thereby making the fishing reel lighter.

[0037] Furthermore, in a preferred embodiment, since the camshaft contact end has a shape defined by a line that has a vertex at a position corresponding to the axis of the spool shaft and is linearly symmetrical about the spool shaft, the camshaft contact end can perform the same function regardless of the rotation direction of the spool. Therefore, regardless of whether the fishing reel 1 is a right-hand rocker arm model or a left-hand rocker arm model, the adjustment mechanism can be constructed from the same components.

[0038] Furthermore, in a preferred embodiment, the distance between the magnetic body and the conductive member can be easily fine-tuned by using the aforementioned stop position defining member and the positioning protrusion as needed. Attached Figure Description

Detailed Implementation

[0058] The embodiments of the present invention are described in detail below. However, the present invention should not be construed as being limited to the following embodiments.

[0059] Figure 2 This is a perspective view showing the appearance of a fishing reel according to one embodiment of the present invention. Figure 3 This is a perspective view showing the appearance of the spool of a baiting reel provided in one embodiment of the present invention. Figure 4 This is a partial cross-sectional view schematically illustrating the internal structure of a baiting fishing reel according to one embodiment of the present invention.

[0060] like Figure 2 As shown, the fishing reel in this embodiment is a double-bearing fishing reel, a low-profile fishing reel used for casting bait. Figure 2 As shown in Figure 3, in this baiting reel 1, the spool 5, which has a spool shaft 2 and a line winding body 4 connected to the spool shaft 2, is rotatably held in the reel frame 6, and the rocker arm assembly 10, which transmits rotational motion to the spool shaft 2, is disposed on the side of the reel. In addition, a star-shaped fishing force adjustment mechanism 11 for adjusting the fishing force is provided on the reel frame side of the rocker arm assembly 10.

[0061] The fishing reel frame 6 has a frame body 7, side covers 8 on both sides of the frame body 7, and a front cover 9 in front of the frame body 7.

[0062] like Figure 2 , 3As shown in Figure 4, the spool 5 includes a spool shaft 2 composed of a rod-shaped member, a sleeve 3 that covers a portion of the spool shaft 2 and is fixed to the spool shaft, and a winding body 4. The winding body 4 includes a cylindrical winding body main body 4-1, flanges 4-2 extending outward from both sides of the winding body main body, and a spool connecting member 4-3. The winding body connecting member 4-3 is a disc-shaped member that extends from approximately the central portion of the spool shaft 2 on the inner surface of the winding body main body 4-1 toward the spool shaft, so that the winding body main body 4-1 and the spool shaft 2 are coaxially connected.

[0063] In another embodiment, a sleeve 3 is provided to cover at least a portion of the spool shaft 2 and is fixed to the spool shaft 2. The spool connecting member 4-3 is connected to the sleeve 3, and the spool 5 is fixed coaxially with the spool shaft 2 via the sleeve 3.

[0064] There are no particular restrictions on the materials used for the various components constituting the spool 5. Suitable materials can be used, taking into account properties such as strength, corrosion resistance, weather resistance, scratch resistance, and density. For example, the spool shaft and sleeve can be made of stainless steel or aluminum alloy, while the winding body can be made of titanium alloy or magnesium alloy.

[0065] like Figure 4 As shown, the spool 5 is held in the reel frame 6 via the bearing 25 and rotates freely about the spool shaft 2, preferably being held in the reel frame 6 in a freely detachable manner.

[0066] like Figure 2 As shown, the rocker arm assembly 10 is disposed on the side of the fishing reel frame 6 (side cover 8), and includes a rocker arm 10-1 rotatable about a rotation axis and a transmission mechanism (not shown) for transmitting the rotational force of the rocker arm to the spool shaft 2. Additionally, in this fishing reel, on the line-feeding side ( Figure 2 Above the paper surface, a horizontal winder 12 for evenly winding the wire is provided on the side opposite to the side where the wire is released. Figure 2 Below the middle paper, there is a clutch lever 13 connected to the clutch mechanism. The clutch switches between a state in which the rotational force of the rocker arm 10-1 can be transmitted to the spool shaft 2, and a state in which the spool 5 is in a free-rotating state and the line wound on the spool 5 can be released.

[0067] When casting bait, with the clutch lever 13 closed, and the fishing line pressed down with the thumb to prevent the spool 5 from rotating unnecessarily, the casting posture is entered. At the moment of casting the bait, the thumb is released from pressing the fishing line, and the bait is cast to the desired location. As a result, the spool 5 is in a free-rotating state, the fishing line is pulled by the bait and released from the reel, and the spool 5 begins to rotate.

[0068] like Figures 4-17As shown, in this embodiment of the baiting reel, in addition to the basic structure described above, a rotation control mechanism 14 is provided to control the rotation of the spool in order to prevent backlash.

[0069] The rotation control mechanism 14 of the baiting fishing reel 1 in this embodiment includes an electromagnetic braking structure 15 and a braking adjustment mechanism 18 for adjusting the braking force.

[0070] The electromagnetic braking structure 15 is a structure that generates a braking force to resist the rotation of the spool through magnetic force, such as... Figures 4 to 8 As shown in 12, it includes a magnetic body 16 and a conductive member 17.

[0071] The magnetic body 16 can be any component that has the function of generating magnetism in the conductive component 17, such as a permanent magnet.

[0072] The conductive component 17 is a conductive component that generates eddy currents on its surface through the action of the magnetic body 16 when it is brought near. For example, it can be made of a non-magnetic conductive material such as aluminum or aluminum alloy. Alternatively, it can be formed by forming copper foil or aluminum foil on a substrate molded from synthetic resins such as acrylonitrile-butadiene-styrene (ABS resin), polyoxymethylene (POM) resin, PPS (polyphenylene sulfide) resin, and polyetheretherketone (PEEK) resin.

[0073] The distance between the paired magnetic bodies 16 and conductive members 17 varies depending on the moving member 19 described later. However, an initial distance between their positions needs to be set so that when they approach each other via the moving member 19, the magnetic body 16 can act on the conductive member 17 to generate eddy currents. This initial position of the paired magnetic bodies 16 and conductive members 17 is determined by the following factors: the stopping position of the moving member determines the placement position of the members; the structure, size, and placement position of the moving member; the placement position, size, and structure of the magnetic body 16 or conductive member 17 connected to the moving member; the structure of the fishing reel frame; and the placement position, size, and structure of the conductive member 17 or magnetic body 16 connected to the fishing reel frame.

[0074] Since adjusting the eddy current via the braking adjustment mechanism is easy, the two are usually configured to be opposite each other in the direction of the online cup axis. For example, as Figure 4 as well as Figure 5 As shown, either the magnetic body 16 or the conductive member 17 is in the braking adjustment mechanism 18, and the other is in the fishing reel frame 6. They are arranged at a position where eddy currents can be generated on the surface of the conductive member 17 by the action of the magnetic body 16 when they approach each other through the braking force adjustment mechanism 18. Typically, they are arranged opposite each other in the direction of the line cup axis.

[0075] According to one implementation, such as Figure 6As shown, the conductive member 17 can be configured as follows: the conductive member 17 is configured as a disk, and a plurality of magnetic bodies 16 are positioned at a certain interval, typically at equal intervals, in the circumferential direction of the cup axis 2, such that when they approach each other through the braking force adjustment mechanism 18, eddy currents can be generated on the surface of the conductive member 17 by the action of the magnetic bodies 16.

[0076] In addition, according to another embodiment, such as Figure 7 As shown in Figure 8, the conductive member 17-1 can be configured as a cylindrical shape coaxial with the spool shaft; on the other hand, the magnetic bodies 16-1 and 16-2 are configured with a U-shaped cross-section, or are composed of a pair of plate-shaped members; the conductive member 17-1 and the magnetic bodies 16-1 and 16-2 are configured such that when they approach each other via the braking force adjustment mechanism 18, the cylindrical end of the conductive member 17-1 can be accommodated in the recess of the magnetic body 16-1 with a U-shaped end face, or in the gap between the magnetic bodies 16-2, which are composed of a pair of plate-shaped members facing each other at a certain interval. In this case, the eddy current generated by the magnetic bodies 16-1 and 16-2 acting on the conductive member 17-1 increases according to the amount of entry at the distal end.

[0077] Additionally, if it is desired to fine-tune the distance between the paired magnetic bodies 16 and the conductive member 17, such as Figure 10 As shown, the thickness of the stop position defining member 20 can be changed according to the predetermined distance between the magnetic body 16 and the conductive member 17, or the stop position of the moving member 19 can be finely adjusted by using multiple stop position defining members 20 overlapping. For example, the stop position defining member 20 can be... Figure 9 The washer 20 shown serves as a fixing member for the fixing stop position defining member 20. From the perspective of easy disassembly and simplification of the structure of the braking force adjustment mechanism described later, a clamping member 26 is preferred.

[0078] Furthermore, the distance between the paired magnetic bodies 16 and the conductive member 17 can also be determined by... Figures 11A to 11CThe stop position defining member 27, with its different structures, is finely adjusted. This stop position defining member 27 is an annular member of a predetermined thickness with a generally circular through hole in the center through which the spool 2 or the spool 2 with the sleeve 3 can pass. The stop position defining member 27 has multiple through holes or bottomed holes or grooves 28-1 to 28-4 of varying depths at predetermined intervals in the circumferential direction. These multiple holes or grooves 28-1 to 28-4 are opened in a manner communicating with the through hole in the center of the stop position defining member 27. On the other hand, the spool 2 or the sleeve 3 is provided with a positioning protrusion 29, which protrudes approximately perpendicularly to the axial direction of the spool 2 near the end of the force-applying member 23 on the side opposite to the moving member side. The through hole 28-1 of the stop position defining member 27 is formed in a shape and size that allows the protrusion 29 to pass through. After the protrusion 29 is inserted into the through hole 28-1, the stop position defining member 27 is rotated so that the protrusion 29 engages with any one of the bottomed holes or grooves 28-2 to 28-4. In a preferred embodiment, such as Figure 11C As shown, the holes (28-1, 28-2, 28-3, and 28-4) located at the center of the central circular through hole have the same depth and increase in depth sequentially along the circumference. On the other hand, the spool shaft 2 or sleeve 3 is provided with two positioning protrusions 29 that protrude in a substantially perpendicular direction relative to the axial direction of the spool shaft 2. The through hole 28-1 of the stop position defining member 27 is shaped and sized such that the protrusions 29 can pass through. After the protrusions 29 are inserted into the through hole 28-1, the stop position defining member 27 is rotated so that the protrusions 29 engage with other bottomed holes or grooves 28-2 to 28-4. According to the predetermined distance between the pair of magnetic bodies 16 and the conductive members 17, the two protrusions 29 provided on these spool shafts 2 or sleeves 3 are fitted with a pair of holes (28-1, 28-2, 28-3 and 28-4 respectively) of appropriate depth, and the stop position defining member 27 is installed, thereby enabling the adjustment of the distance between the pair of magnetic bodies 16 and the conductive members 17.

[0079] like Figures 12 to 16 As shown, the braking force adjustment mechanism 18 includes: a camshaft 22, a moving member 19, and a force-applying member 23. The camshaft 22 is provided on the line cup shaft 2 or the sleeve 3. The moving member 19 has a camshaft contact end 21 that can engage with the camshaft 22 and is connected to a magnet 16 or a conductive member 17. The force-applying member 23 applies force to the moving member from one end side along the direction of the line cup shaft.

[0080] like Figures 12 to 14As shown, the camshaft 22 protrudes in a direction substantially perpendicular to the axial direction of the spool shaft 2, is disposed on the spool shaft 2 or sleeve 3, and has a substantially cylindrical shape. The camshaft 22 can be formed by, for example, providing a bottomed or through hole of a predetermined diameter on the spool shaft 2 or sleeve 3, and inserting a rod-shaped member having the same diameter as the bottomed or through hole and a predetermined height. In this case, for example, if a threaded groove is formed on the inner wall of the bottomed or through hole, threads are formed on a portion of the camshaft 22, thereby enabling the camshaft 22 to be screwed and fixed in the bottomed or through hole. Alternatively, a portion of the camshaft 22 can be bonded to the inner wall surface of the bottomed or through hole using an adhesive.

[0081] like Figure 12 , 13 As shown in Figures 15 and 16, the movable member 19 is a cylindrical member with a circular cross-section that is capable of rotating coaxially with the spool shaft 2 within a certain range and moving along the axial direction of the spool shaft 2. The movable member 19 is configured such that the spool shaft 2 or the spool shaft 2 with a sleeve 3 passes through the hollow space of the movable member 19, and the camshaft 22 provided on the spool shaft 2 or the sleeve 3 engages with the camshaft contact end 21 of the movable member 19.

[0082] Furthermore, the movable member 19 is connected to the magnetic body 16 or the conductive member 17 at or near the end of the cup shaft 2 opposite to the camshaft contact end 21 in the axial direction. Therefore, the movable member 19 is designed and configured such that the magnetic body 16 or the conductive member 17 connected to or near one end of it can be positioned at a predetermined distance relative to the conductive member 17 or the magnetic body 16 disposed at a predetermined position on the reel holder 6. On the other hand, the camshaft 22 engages with the other end 21 to enable a predetermined operation.

[0083] The camshaft contact end 21 only needs to be shaped by a line inclined relative to the axis of the spool shaft 2. The degree of inclination angle can be determined by considering the rotational difference between the assumed moving member 19 and the spool shaft 2, thereby changing the inclination angle. If the inclination angle relative to the axis of the spool shaft is made acute, the movement speed of the moving member 19 relative to the rotational difference between the moving member 19 and the spool shaft 2 (in other words, the difference in rotational speed with respect to the spool) can be increased. Conversely, if the inclination angle is made obtuse, the movement speed of the moving member 19 relative to the rotational difference between the moving member 19 and the spool shaft 2 can be decreased. Therefore, the shape of the camshaft contact end 21 can be determined by considering this point.

[0084] Furthermore, since the same component can be used regardless of whether the rocker arm assembly is located on the left or right, the camshaft contact end 21 is preferably shaped by a line that is linearly symmetrical about the spool shaft. According to a preferred embodiment, such a camshaft contact end 21 has a shape defined by a line that has a vertex at a position corresponding to the axis of the spool shaft 2, and is inclined vertically away from the axis of the spool shaft from the vertex toward the side opposite to the magnetic or conductive member side, and is linearly symmetrical about the spool shaft.

[0085] For example, it has the following configurations: a V-shape rotated 90 degrees clockwise and symmetrical about the spool axis; a U-shape rotated 90 degrees clockwise and symmetrical about the spool axis; and a shape in which two symmetrical arc-shaped lines are connected with their vertices at positions corresponding to the axis of the spool axis.

[0086] In the fishing reel of the present invention, the moving member 19 does not have a cam groove, and can be said to have a structure in which approximately half of the partition used to form the cam groove is removed. As a result, the camshaft is constrained by only one partition and, depending on the situation, is temporarily in a non-contact state with the partition, and is not subject to frictional resistance from the two partitions. In addition, the substrate surrounding it used to form the cam groove is approximately halved at the camshaft contact end, enabling the lightweighting of the moving member.

[0087] like Figure 10 As shown in 11, 12, and 16, the force-applying member 23 applies force to the moving member 19 from the end side of the moving member 19 connected to the magnetic body 16 or the conductive member 17, along the spool axis towards the rocker arm assembly side (the side opposite to the end connected to the magnetic body 16 or the conductive member 17). The force-applying member 23 can be any member with this function; for example, it can be made of a known elastic member such as a spring or rubber. In the case of a spring, the force can be easily adjusted by adjusting its material and thickness.

[0088] In addition, although the force-applying member 23 only needs to be configured to perform the above-mentioned functions, it is generally configured to be directly adjacent to the end of the moving member or adjacent to it via other members, and is positioned by the stop position defining member 20 installed on the side opposite to the moving member side to maintain the force-applying state.

[0089] In a baiting reel equipped with a rotation control mechanism 14 having the aforementioned electromagnetic braking structure 15 and braking adjustment mechanism 18, when there is a discrepancy between the amount of fishing line supplied from the spool and the amount of fishing line pulled by bait, the rotation control mechanism controls the rotation speed of the spool based on the difference between the two, thereby preventing the spool from rotating excessively.

[0090] Specifically, such as Figure 17 As illustrated, since the spool (not shown) rotates at a low speed in the initial stage of casting, the rotational force generated by the spool (not shown) is less than the force exerted by the force-applying member 23. In this state, since the moving member 19 rotates integrally with the spool shaft 2, there is no difference in rotational speed between the moving member 19 and the spool shaft 2. Therefore, the camshaft 22 remains at the apex 21-1 of the camshaft contact end 21. As a result, the moving member 19 remains in its initial position, and the magnetic body 16 or conductive member 17 connected to it is located at the furthest point relative to the other paired conductive member 17 or magnetic body 16, resulting in minimal braking force against the rotation of the spool (not shown).

[0091] On the other hand, when the rotation of the spool (not shown) increases with the flight speed of the bait, the rotational force of the spool exceeds the force of the force-applying member 23. In this state, a rotational difference is generated between the rotation of the moving member 19 and the rotation of the spool shaft 2. The camshaft 22, in contact with the camshaft contact end 21, moves from the apex 21-1 along the camshaft contact end 21, causing the moving member 19 to move axially along the spool shaft 2 towards the side opposite to the camshaft contact end 21. Figure 17 (Left side of the paper). As a result, the magnetic member 16 or conductive member 17 connected to the moving member 19 moves toward the conductive member 17 or magnetic member 16 held by the reel holder (not shown). The moving speed of the conductive member 17 or magnetic member 16 depends on the rotational force of the spool (not shown), and the conductive member 17 or magnetic member 16 can move to a maximum stop position specified by the stop position defining member 20. Based on the distance between the paired conductive members 17 and magnetic members 16, a braking force is generated to resist the rotation of the moving member 19, and a further braking force to resist the rotation of the spool (not shown) is generated via a cam mechanism. As a result, excessive rotation of the spool (not shown) can be reduced, preventing backlash.

[0092] Furthermore, in this fishing reel, the moving member 19 is cut into a V-shape to reduce weight, and the camshaft 22 is not subject to contact resistance from the two partitions. Therefore, the camshaft 22 can be moved with less force.

[0093] During the stage where the bait falls into the water after exceeding its apex, the rotational speed of the spool (not shown) is reduced by the rotational control mechanism, and the force of the camshaft 22 pressing against the camshaft contact portion 21 decreases. Then, when the force applied by the force-applying member (not shown) exceeds the rotational force of the spool, the camshaft 22 moves along the camshaft contact end 21 or temporarily without contacting the camshaft contact end 21 towards the apex 21-1 of the camshaft contact end 21, and finally returns to the apex 21-1 of the camshaft contact end 21. As a result, the moving member 19 moves axially along the spool shaft 2 to the rocker arm side (the side opposite to the end connected to the magnetic or conductive member). Figure 17 (On the right side of the paper), it eventually returns to its initial position. As a result, the magnetic body 16 or conductive member 17 connected to the moving member 19 moves away from the conductive member 17 or magnetic body 16 held by the reel holder (not shown), and the electromagnetic force on the conductive member 17 from the magnetic field of the magnetic body 16 decreases. Therefore, the braking force against the rotation of the spool also decreases, reaching its minimum when it finally returns to its initial position.

[0094] Furthermore, in this fishing reel, the moving member 19 is cut into a V-shape to reduce weight, and the camshaft 22 is not subject to contact resistance from the two partitions. Therefore, in the aforementioned reset action, the camshaft 22 can be moved with less force, thereby moving the moving member 19.

[0095] In this fishing reel, such actions avoid unnecessarily reducing the flight distance and provide appropriate braking force to the spool, thereby effectively preventing recoil.
