Description

Technical Field

[0001] The present invention relates to various fishing reels such as a double-bearing type reel, a spinning type reel, a single-bearing type reel, an electric reel, etc. The present invention also relates to a corrosion member mounted on such a fishing reel. Background Art

[0002] The above-mentioned fishing reel includes a plurality of components for performing a predetermined function, and is used in an environment (under an electrically conductive atmosphere) near seawater or water. The above-mentioned components are organically connected (contacting, close) and are formed of various materials. Therefore, a potential difference is generated at the part where different materials with a potential difference are connected to each other, and corrosion (galvanic corrosion) is promoted in the use environment exposed to the above-mentioned electrically conductive atmosphere.

[0003] Therefore, in order to prevent such corrosion, surface treatment such as forming an insulating coating on the surface of the component is implemented (for example, refer to Patent Document 1). In addition, sealing materials are provided between the components to prevent seawater or water from intruding and prevent corrosion (for example, refer to Patent Document 2).

[0006] Patent Document 2: Japanese Patent Application Publication No. 2003-023934 Summary of the invention

[0007] However, during actual fishing or when moving or transporting the fishing site, the fishing reel may be damaged due to contact with other objects or falling. Therefore, it may be exposed to seawater or water in an uninsulated state, and is often in a state where corrosion is likely to occur. In addition, since the fishing reel repeatedly winds the fishing line containing seawater or water around the reel and releases it, seawater or water easily penetrates into the interior through the gap near the reel, which has a structural problem of inducing corrosion.

[0008] Furthermore, in order to use the fishing reel in good condition for a long time, it is necessary to perform regular maintenance and check the extent and progress of corrosion. However, corrosion may progress in parts that are difficult to observe, making it difficult to maintain good performance for a long time.

[0009] The present invention has been made in view of the above-mentioned problems, and the technical problem to be solved is to provide a fishing reel and a corrosion component installed in such a fishing reel, which can effectively prevent corrosion of main components.

[0010] The present invention prevents corrosion of main components by a concept completely different from the corrosion prevention means used in conventional fishing reels. That is, in order to achieve the above-mentioned object, the present invention is a fishing reel in which various components are arranged in a reel body, a fishing line is wound onto a spool, and a fishing line wound onto the spool is released, wherein components formed of different materials are arranged in a contact state or a close state with each other, and a corrosion component having a higher potential difference than the potential difference between the components of the different materials is detachably arranged in the components in a conductive state.

[0011] In the conventional fishing reel, corrosion prevention means are adopted for the components themselves, or a sealing structure is provided to prevent seawater or water from entering from the outside, thereby preventing the components from being corroded as much as possible. However, in the present invention, such conventional corrosion prevention means are not adopted, but a corrosion member that actively promotes corrosion is provided, thereby preventing corrosion of the components of the fishing reel. The corrosion member can be made of a material having a higher potential difference than the potential difference generated between components formed of different materials, specifically, a material having a large ionization tendency (for example, zinc, titanium, aluminum, magnesium, etc.).

[0012] The material with a high ionization tendency that becomes the corrosion component can be selected according to the materials of the components. By making such a material with a high ionization tendency contact the component, even if an electrically conductive liquid such as seawater or water intrudes and electrons flow, electrons flow preferentially to the corrosion component, thereby preventing corrosion of the component. That is, the feature of the present invention is that the corrosion component is preferentially corroded, and the technical concept is different from the above-mentioned existing corrosion-resistant structure of the component.

[0013] Furthermore, by constructing the structure so as to actively cause corrosion of the corroded member, the user can also grasp the maintenance period of the fishing reel to a certain extent according to the corrosion state.

[0014] In addition, the present invention is a corrosion component installed in a fishing reel, characterized in that various components arranged in the reel body are formed of heterogeneous materials of different raw materials, and the parts where the components of the heterogeneous materials are arranged in a contact state or a close state are formed of a material with a higher potential difference than the potential difference between the components of the heterogeneous materials.

[0015] According to the present invention, it is possible to provide a fishing reel and a corrosion member mounted on such a fishing reel, which can effectively prevent corrosion of main components. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figures 1 to 5 It is a figure which shows the 1st Embodiment (dual-bearing type fishing reel) concerning this invention.

[0033] The reel body 1 of the dual-bearing type reel according to the present embodiment comprises a left side plate 1A, a right side plate 1B, and a reel 3 rotatably supported between the two side plates 1A and 1B. In the present embodiment, a handle 5 is provided on the right side plate 1B, and the reel 3 is rotationally driven by a known reeling drive mechanism by reeling the handle 5 (right handle type).

[0034] The reel body 1 includes a frame 7 constituting left and right side plates 1A and 1B. The frame 7 is integrally formed of a metal material such as an aluminum alloy, and the left frame 7A directly constitutes the left side plate 1A, while the cover 15 is attached to the right frame 7B to constitute the right side plate 1B.

[0035] The frame 7 includes a connection portion connecting the left plate 1A and the right plate 1B. In the present embodiment, a front connection portion 7C is provided in front of the reel 3, a rear connection portion 7D is provided behind the reel 3, and a lower connection portion 7E is provided below the reel. These connection portions are formed integrally with the left frame 7A and the right frame 7B. In addition, a reel foot 8 (the reel foot may also be formed integrally with the frame) to be mounted on a reel seat of a fishing rod is integrally mounted on the lower connection portion 7E.

[0036] The left side plate 1A is provided with an annular recess 7a for accommodating the flange 3a of the spool 3. In addition, a recess 7b is formed in the center region of the left side plate 1A, and a bearing 10 is disposed in the recess 7b to rotatably support the left end of the drive shaft 3A of the spool 3. In addition, a known spool brake 12 is provided in the left side plate 1A to prevent the spool 3 from rotating in the line release direction. The spool brake 12 includes a sliding rod 12a protruding from the outer side surface of the left side plate 1A, and by sliding the sliding rod 12a, a state in which the spool 3 is prevented from rotating in the line release direction and a state in which the spool 3 is allowed to rotate in the line release direction can be switched.

[0037] The right frame 7B is formed in an annular shape and has a circular opening 7d for removing the reel 3 from the handle side. As described above, by installing the cover 15, the right frame 7B constitutes the right side plate 1B, and various functional parts (constituent components) such as a winding drive mechanism, a force release mechanism, and a clutch mechanism for transmitting the rotational driving force of the handle 5 to the reel are accommodated in the right side plate 1B.

[0038] The drive shaft 3A is fixedly passed through the center of the reel 3, and the left end is rotatably supported on the left plate 1A (left frame 7A) through a bearing 10. In addition, a bearing 3C is provided on the right side of the reel 3 of the drive shaft 3A, and a pin 3D is provided on the axially outer side thereof, and the pinion 23 axially slid by the clutch mechanism is engaged and disengaged with the pinion 23. The drive shaft 3A, which is closer to the axially outer side than the setting position of the pin 3D, is reduced in diameter and passed through the pinion 23.

[0039] A cover 15 is detachably fixed to the right frame 7B, and the right frame 7B and the cover 15 constitute the right side plate 1B of the reel body 1. The cover 15 is formed in a concave shape to form a storage space S between the cover 15 and the right frame 7B, and the various functional parts described above are arranged in the storage space S.

[0040] Hereinafter, various functional parts disposed in the storage space S will be referred to. Figure 6 Provide explanation.

[0041] As described above, the storage space S is provided with: a winding drive mechanism 20 for transmitting the rotational driving force of the handle 5 to the reel 3; a release mechanism 50 for applying a desired braking force to the fishing line released from the reel 3; and a clutch mechanism 70 for switching the reel to a winding state / free rotation state, etc.

[0042] In this embodiment, the housing space S is formed between the mounting plate 16 mounted on the cover body 15 and the cover body 15, and the above-mentioned mechanisms are arranged in the housing space S. That is, when the cover body 15 is removed from the right frame 7B, the winding drive mechanism 20, the force release mechanism 50, and the clutch mechanism 70 are located on the cover body 15 side of the mounting plate 16, and the components of each mechanism are not exposed (even if the cover body 15 is removed from the right frame 7B, they will not be scattered).

[0043] The mounting plate 16 is formed in a substantially cylindrical shape with a support portion 16a and an annular support portion 16b. The support portion 16a is circular and plate-shaped, and the annular support portion 16b is formed at the outer peripheral end of the support portion 16a and protrudes toward the winding drum side. A flange portion 16c is integrally formed on the support portion 16a from the annular support portion 16b toward the radial outer side, and a plurality of fixing screws 17 are screwed into the flange portion 16c toward the cover body side, thereby screwing the mounting plate 16 to the inner surface side of the cover body 15 (see Figure 6 ) In addition, the annular support portion 16b is fitted into the inner surface of the circular opening portion 7d formed in the right frame 7B.

[0044] like Figure 6 As shown, the flange portion 16c is partially formed with a plurality of cutouts 16d along the circumferential direction, and the fixing portion 15a formed on the cover body 15 is located at the cutout portion. The fixing portion 15a is formed at a plurality of locations from the annular surface of the cover body 15 toward the radial inner side, and small screw holes for fixing are formed at the same time. In addition, fixing holes are formed at positions corresponding to the small screw holes on the side surface of the right frame 7B. Thus, the small screw holes of the cover body 15 are aligned with the fixing holes of the right frame 7B, and the small screws 19 are screwed in from the outside to fix the cover body 15 to the right frame 7B.

[0045] A through hole 16e is formed in the center of the support portion 16a of the mounting plate 16, and a support portion (annular wall portion 16f) is formed around the through hole 16e in a manner protruding toward the reel side. In addition, a recess 16g is formed in a portion of the outer peripheral side of the support portion 16a, which is open to the cover body side. The pinion 23 constituting the winding drive mechanism 20 is arranged in the through hole 16e, and the root end of the handle shaft 5A constituting the winding drive mechanism 20 is arranged in the recess 16g.

[0046] Here, the structure of the retracting drive mechanism 20 will be described.

[0047] As described above, in this embodiment, the handle 5 for rotationally driving the reel 3 is disposed on the right side plate 1B, and the reel drive mechanism 20 is disposed in the storage space S between the mounting plate 16 and the cover body 15. The reel drive mechanism 20 includes: a handle shaft 5A on which the handle 5 is mounted; a transmission gear 21 rotatably mounted on the handle shaft 5A; and a pinion 23 meshing with the transmission gear 21.

[0048] A handle 5 for winding operation is installed at the end of the handle shaft 5A, and the handle shaft is rotatably supported in the right side plate by bearings 25 and 26. The bearing 25 is arranged between the handle shaft and the cover body 15, and the bearing 26 is arranged between the handle shaft and the recess 16g formed in the right frame 7B. The pinion 23 meshing with the transmission gear 21 allows the drive shaft 3A of the reel to pass through, and is supported to be axially slidable relative to the drive shaft 3A. In this embodiment, the two sides of the pinion 23 are rotatably supported by bearings 27 and 28 respectively. At this time, the bearing 27 is arranged in the through hole 16e part of the mounting plate 16, and the bearing 28 is arranged in the known brake device 29, which is installed in the cover body 15 and supports the end face of the drive shaft 3A of the reel, thereby applying a braking force to the rotation of the reel.

[0049] A known one-way clutch 30 is provided between the handle shaft 5A and the cover 15, which allows the handle 5 to rotate in the fishing line winding direction and prevents reverse rotation. In addition, a known drag mechanism 50 is provided on the handle shaft 5A portion, which applies a desired braking force to the fishing line released from the spool 3. The drag mechanism 50 includes: a plurality of brake plates 51, which are provided in an annular recess 21a formed in the transmission gear 21; a ratchet 52, which is fixed to the handle shaft 5A in an axial direction and is in surface contact with the transmission gear 21; and an operating knob 55, which is provided on the handle shaft 5A and moves axially by rotation. Therefore, when the operating knob 55 is rotated, the brake plates 51 are pressed by the inner ring of the one-way clutch 30, and a desired pressing force is applied to the transmission gear 21 between the handle shaft 5A and the handle shaft 5A. That is, by rotating the operating knob 55 and adjusting the pressing force on the brake plate 51 , a desired drag can be applied to the fishing line released from the spool 3 .

[0050] Furthermore, a locking claw (not shown) can be engaged with the ratchet wheel 52, and when the reverse rotation prevention function of the one-way clutch 30 slips, the handle shaft 5 can be reliably prevented from rotating reversely.

[0051] A known clutch mechanism 70 is provided on the mounting plate 16, which switches the winding state / free rotation state of the spool 3. The clutch mechanism 70 includes: an operating member 71, which is provided on the right side plate 1B and supported to be rotatable along the outer peripheral surface; a clutch plate 72, which is rotatably supported on the mounting plate 16 and rotates with the operation of the operating member 71; and a matching member 74, which matches with the circumferential groove formed on the outer peripheral surface of the pinion gear 23, and the pinion gear 23 slides in the axial direction by the rotation operation of the operating member 71. That is, by operating the operating member 71 to slide the pinion gear 23 in the axial direction, the end portion 23b of the pinion gear 23 with a non-circular cross section is engaged and disengaged with the pin 3D provided on the drive shaft 3A of the spool 3, thereby being configured to be switchable between a power transmission state (clutch engagement (ON) state) and a power cutoff state (clutch disengagement (OFF) state). At this time, a reset mechanism is provided on the ratchet 52 and the mounting plate 16, which automatically resets the clutch mechanism from a disengaged (OFF) state to an engaged (ON) state when the handle is retracted.

[0052] The cover body 15 is provided with a bulging portion 15A bulging in a substantially semicircular shape so as to accommodate a portion of the transmission gear 21 mounted on the handle shaft 5A. The bulging portion is mounted to the right frame 7B by bolts and is closed by a substantially semicircular closing member 61. That is, as described above, when the cover body 15 with the mounting plate 16 mounted thereon is mounted on the right frame 7B, the bulging portion 15A is directly closed by the closing member 61 mounted on the right frame 7B.

[0053] As described above, a plurality of components (functional parts) are housed in the right side plate of the reel body 1, and these are supported on the mounting plate 16 as described above. At this time, the plurality of components are formed of different materials of different raw materials and are arranged in a contact state or a close state. Therefore, if an electrically conductive liquid such as seawater or water is attached or exposed to such an atmosphere, the flow of electrons is generated due to the potential difference, inducing corrosion. For example, at the through hole 16e of the mounting plate 16, there will be a condition that is prone to corrosion, such as the bearing 27 portion arranged between the support portion (annular wall portion 16f) protruding toward the reel side and the side portion of the pinion 23 (such corrosion will reduce the rotation performance).

[0054] In this embodiment, the corrosion member 100 having a higher potential difference than the potential difference between the mounting plate 16 and the components made of different materials (components of the winding drive mechanism 20, the clutch mechanism 70, and mounting components such as fixing bolts) is detachably provided on the mounting plate 16 in a conductive state. The corrosion member 100 is made of a material with a large ionization tendency, such as zinc, titanium, aluminum, magnesium, etc., and is selected and used according to the materials of the components.

[0055] By making the corrosion component formed by such a material with a large ionization tendency contact the constituent component (mounting plate 16), even if an electrically conductive liquid such as seawater or water invades and generates electron flow, electron flow is preferentially generated on the corrosion component 100 and corrosion occurs, thereby effectively preventing corrosion of other constituent components.

[0056] The corrosion member 100 of this embodiment is composed of a plate-like member (e.g., a zinc plate) and is detachably mounted on the opposite side of the roll of the mounting plate 16. Figure 6 As shown, the corrosion component 100 is detachably mounted on the flat surface of the support portion 16a of the mounting plate 16 by means of fixing means (a plurality of small screws 102), and conduction is achieved between the mounting plate 16 and the small screws 102. In addition, since the corrosion component 100 is arranged inside the right side plate (a position that cannot be observed from the outside), the corroded component will not be exposed, and the appearance will not be reduced. In addition, the corrosion component will not be damaged by falling or colliding with other objects, and its function can be exerted. Moreover, by removing the cover body 15 from the right frame 7B to expose the mounting plate 16, the corrosion condition of the corrosion component 100 can be confirmed (the maintenance period can be grasped).

[0057] As such, unlike the existing structure that adopts corrosion prevention means for the components themselves or provides a sealing structure to prevent seawater or water from entering from the outside to prevent the corrosion of the components as much as possible, in this embodiment, a corrosion member 100 that actively promotes corrosion is provided, thereby preventing the corrosion of the components of the fishing reel (corrosion of the main components) to improve the corrosion resistance and prevent the operation from deteriorating. In addition, by providing the corrosion member 100 to actively cause corrosion, the user can also grasp the maintenance period of the fishing reel to a certain extent according to its corrosion state.

[0058] In addition, in the present embodiment, since the corrosion member 100 is formed in a plate shape, a large space is not required, and the corrosion member can be efficiently arranged. In particular, since the support portion (annular wall portion 16f) of the mounting plate 16 is formed in an annular shape in a protruding manner, corrosion that is likely to occur in the bearing 27 portion arranged in the central area thereof can be effectively suppressed. In addition, since the fishing line with seawater or water attached is wound around the reel 3, moisture is likely to enter the inside of the side plate from the end edge of the reel, that is, the flange portion, but by arranging the corrosion member 100 on the reel-opposing surface side of the mounting plate 16, it can be effectively corroded, and corrosion of the main components can be prevented.

[0059] Moreover, if the fixing screw 19 is rotated to remove the cover body 15 from the right frame 7B, the mounting plate 16 is fixed to the side of the cover body 15, so that the various components of the winding drive mechanism 20, the force release mechanism 50, and the clutch mechanism 70 installed inside the cover body 15 will not be exposed, and only the corroded component 100 can be easily replaced, thereby improving the maintainability.

[0060] Figure 7 It is a diagram showing a modified example of the above-mentioned structure.

[0061] This modification shows an example in which the corrosion member 100 is formed into a plate-like member and is attached to the surface of the support portion on the reel side of the mounting plate 16 .

[0062] In such a structure, the corrosion member 100 can be replaced together with the mounting plate 16. In addition, the corrosion member 100 may be covered on the support portion 16a in a removable manner and peeled off when replaced.

[0063] Figure 8 It is a diagram showing a configuration example of the second embodiment (spinning type reel) of the fishing reel according to the present invention.

[0064] As long as the corrosion component 100 as described above is formed with a larger potential difference between the component on which it is installed, specifically, as long as it is formed with a higher potential difference than the potential difference between the component and other components in contact (closeness), its installation position is not limited, and the corrosion of the other components can be effectively prevented.

[0065] exist Figure 8 The spinning reel 200 for fishing shown in the figure has a reel body 202 formed with a reel foot 202A to be mounted on a fishing rod. A handle shaft is rotatably supported in the reel body via a bearing, and a handle 203 to be reeled is mounted at the end of the handle shaft. The handle 203 includes a handle arm 203A and a handle knob 203B at the top thereof, and is configured so that the handle 203 can be reeled by gripping the handle knob 203B. In addition, a known driving force transmission mechanism is connected to the handle shaft, and the rotor 210 is driven to rotate with the rotation of the handle 203, and the spool 205 is moved forward and backward by a known swing mechanism.

[0066] The reel 205 is made of, for example, a metal with a relatively low specific gravity, such as aluminum, aluminum alloy, magnesium alloy, or a synthetic resin material, and has a fishing line winding body 205a for winding the fishing line, a front flange portion 205b and a rear flange portion (skirt) 205c for regulating the fishing line winding amount of the fishing line winding body 205a in the front-to-back direction.

[0067] A pair of support arms 211, 212 are formed on the rotor 210 to extend axially forward at intervals of about 180 degrees and to face each other. The reel 205 is located between the pair of support arms and is driven to reciprocate forward and backward. At the top end of each support arm 211, 212, a line take-up frame support member 214, 215 is supported to be rotatable between a fishing line winding position and a fishing line releasing position. In addition, the root end of a semi-circular line take-up frame 217 is mounted on each of the line take-up frame support members 214, 215, and the line take-up frame 217 can rotate together with the line take-up frame support members 214, 215. In addition, at the top end of one of the line take-up frame support members 214, a fishing line guide device (fishing line drum) 250 is provided to guide the fishing line to the reel.

[0068] The spinning reel of the above structure is as follows: when the handle 203 is rotated, the rotor 210 is rotationally driven by the driving force transmission mechanism, and the spool 205 is reciprocated forward and backward by the swing mechanism. As a result, the fishing line is evenly wound around the fishing line winding body 205a of the spool 205 by the fishing line guide 250 of the take-up frame support member 215 that rotates together with the rotor 210.

[0069] Even in the spinning type reel as described above, the corrosion member 100 may be detachably provided at various locations.

[0070] For example, Fig. 9 As shown, the rotor 210 can be detachably mounted on the upper surface of the rotor 210 that is driven to rotate using a small screw 110.

[0071] In addition, if Fig.10 As shown in the figure, the knob cover 203C may be detachably mounted on the handle knob 203B provided at the top end of the handle arm 203A using a screw 110. Alternatively, although not shown, the knob may be detachably mounted at any position inside the handle arm 203A (a position that is difficult to be seen from the outside).

[0072] In addition, if Fig.11 As shown in the figure, the known rear cover 230 installed at the rear end of the reel body 202 can be removed, and the corrosion member 100 can be detachably installed in the reel body at the opening portion (inside the rear cover). In addition, the corrosion member can be installed on the inner surface of the rear cover 230 (inside the rear cover) to replace the rear cover 230.

[0073] Furthermore, the corrosion member 100 may be detachably mounted on a reel foot 202A mounted on a reel foot fixing portion of a fishing rod, or Figures 2 to 4 The bottom of the foot of the reel foot 8 of the dual bearing type reel is shown.

[0074] As described above, the corrosion member 100 can be set in various locations such as the reel body, the handle, the reel foot and the line guide device, and the shape or installation direction of the corrosion member can be variously deformed according to the setting position.

[0075] By installing the corrosion-reducing member on any component of the cable reel, it is possible to effectively suppress corrosion between the component and other components that are in contact (including close proximity). For example, it is possible to effectively suppress corrosion at the fixing member (bolt, rivet, etc.) that connects various functional parts and components that constitute the driving force transmission mechanism and the swing mechanism.

[0076] Next, the results of an experiment conducted by continuously immersing a fishing reel equipped with the above-mentioned corrosion component in seawater and analyzing the change in the state of the component will be described.

[0077] Fig.12 The photographs show the changes in the state of a corrosion member (composed of a ZDC plate, a zinc alloy for die casting, and the portion surrounded by a circle) fixed to the surface of the drum side of a mounting plate with screws and immersed in seawater.

[0078] The immersion in seawater was repeated 7 times for 1 hour. At this time, white precipitates (concavities and convexities) were observed on the surface of the ZDC plate, which was the corroded member, indicating that corrosion had occurred.

[0079] Fig.13 The photograph is a constituent member in a state of contacting a mounting plate, and shows a conventional protruding region of a SUS handle shaft and an anodized aluminum-treated drag knob mounted thereon.

[0080] (a) indicates that Fig.12 The corrosion component shown is arranged on the structure of the mounting plate, (b) represents the Fig.12 The corrosion components shown are mounted on the mounting plate structure, Fig.12 Likewise, all of them show the state when immersing in seawater for one hour continuously and repeating this process 7 times.

[0081] As can be seen from the comparison photographs, the following results were obtained: when the corroded member was mounted on the mounting plate, corrosion occurred on the corroded member, but corrosion did not progress on the main constituent member.

[0082] Fig.14 The photographs show the test results comparing the case where a corrosion component is installed inside the root end of the handle arm (the part attached to the handle shaft) and the case where a corrosion component is not installed. The handle arm is an anodized aluminum alloy (A6061) component, and the handle knob is riveted to the top end with SUS rivets.

[0083] The left side of (a) is a member in which an anodized aluminum plate (black) is clamped at the root end to prevent the nut from loosening, and the right side of (a) is a member in which a zinc plate (white) of the same shape is clamped.

[0084] These two handle arms were subjected to seawater spraying for 3 weeks. At this time, corrosion occurred around the SUS rivets on the component sandwiching the aluminum plate (left side of (b)), while no corrosion was observed around the SUS rivets on the component sandwiching the zinc plate (right side of (b)).

[0085] This is considered to be because although aluminum has a greater tendency to ionize than zinc, if aluminum anodizing is performed as described above, the area to which electricity is conducted becomes smaller, and the effect is obtained even if the above-mentioned zinc plate is installed.

[0086] As in the above-mentioned embodiment, the present invention is characterized in that a corrosion component is detachably installed inside the reel body of the fishing reel or on the surface of a component of the reel body exposed to the outside (preferably in a position that cannot be visually observed), and regarding the corrosion component, when corrosion progresses, maintenance work of replacing a dedicated corrosion component can be performed.

[0087] Therefore, the present invention includes a corrosion member that can be detachably mounted on a portion where components of different materials are arranged in a contact state or a close state, and is formed of a material having a higher potential difference than the potential difference between components of different materials. Such a corrosion member can be manufactured and sold as a replacement part (special product), and its shape can be determined according to the location or method of installation, or it can be made into a block shape in addition to a plate shape, or it can be made into a shape having a certain function.

[0088] Furthermore, since such a corrosion member is formed in a zinc plate shape, it has excellent workability and can achieve cost reduction.

[0089] As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, Various deformation|transformation is possible.

[0090] As a fishing reel, in addition to the above-mentioned type of reel, it can also be applied to various reels such as electric reels and single bearing type reels, and various changes can be made to the installation position. In addition, since corrosion does not only occur due to contact between metal components, but also occurs even in the case of dissimilar materials such as carbon and aluminum, it is sufficient to install appropriate corrosion components in consideration of the potential difference generated between the constituent components.
