Description

[Technical field]

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

[0002] The above-mentioned fishing reel includes many components to perform a predetermined function, and is used in an environment (conductive atmosphere) close to seawater or water. The components are organically related (contacted, close to each other) and made of various materials. For this reason, a potential difference occurs in a portion where different materials with a potential difference are related to each other, and corrosion (galvanic corrosion) is promoted in the above-mentioned usage environment exposed to the conductive atmosphere. In order to prevent such corrosion, surface treatments such as forming an insulating coating on the surfaces of the components are carried out (see, for example, Patent Document 1). Also, sealing materials are interposed between the components to prevent the intrusion of seawater or other water and prevent corrosion (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2007-159427 [Patent Document 2] JP2003-023934A Summary of the Invention [Problem to be solved by the invention]

[0004] Meanwhile, fishing reels can be damaged by contact with other objects or being dropped while fishing or while moving or transporting to a fishing spot. For this reason, they can be exposed to seawater or other water in an environment where they are unable to insulate, and are often prone to corrosion. In addition, since fishing reels repeatedly wind and release fishing line containing seawater or water onto the spool, seawater or water can easily get into the reels through gaps near the spool, creating a structural problem that induces corrosion.

[0005] Furthermore, in order to keep a fishing reel in good condition for a long period of time, it is necessary to regularly perform maintenance and check the degree and progress of corrosion. However, corrosion can progress in parts that are hard to see, making it difficult to maintain good performance for a long period of time.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a fishing reel that can effectively prevent corrosion of major components, and a corrosion-resistant member to be attached to such a fishing reel. [Means for solving the problem]

[0007] The present invention prevents corrosion of major components with a concept completely different from that of corrosion prevention means used in conventional fishing reels. That is, in order to achieve the above-mentioned object, the present invention provides a fishing reel having various components arranged on a reel body, which winds fishing line onto a spool and releases the fishing line wound on the spool, in which components made of different materials are arranged in contact or close proximity to each other, and a corroding member that has a potential difference larger than the potential difference between the components made of the different materials is arranged detachably and conductively to the components.

[0008] Conventional fishing reels are constructed to prevent corrosion of the components as much as possible by providing corrosion prevention means to the components themselves or by providing a seal structure to prevent seawater or other water from entering from the outside, but in the present invention, instead of using such conventional corrosion prevention means, a corrosion member that actively promotes corrosion is provided to prevent corrosion of the components of the fishing reel. The corrosion member can be made of a material that creates a larger potential difference than the potential difference that occurs between components made of different materials, and specifically, it is made of a material that has a high ionization tendency (e.g., zinc, titanium, aluminum, magnesium, etc.).

[0009] The material with a high ionization tendency that becomes the corroding member can be selected according to the materials of the components. By keeping such a material with a high ionization tendency in contact with the components, even if an electrically conductive liquid such as seawater or water enters and causes a flow of electrons, the flow of electrons will occur preferentially in the corroding member, making it possible to prevent corrosion of the components. In other words, the present invention is characterized by preferentially corroding the corroding member, and is a technical concept different from the above-mentioned conventional corrosion protection structure for components.

[0010] In addition, by constructing the fishing reel so that the corroded members are actively corroded, it is possible to allow the user to know, to some extent, when maintenance of the fishing reel is required, depending on the state of corrosion.

[0011] The present invention also features a corrosion-resistant member that is attached to a fishing reel, and is characterized in that various components arranged on a reel body are formed from different materials, the components are detachable from portions where the components of the different materials are arranged in contact or close proximity to each other, and the components are formed from a material that creates a potential difference that is greater than the potential difference between the components of the different materials. Effect of the Invention

[0012] According to the present invention, there is provided a fishing reel capable of effectively preventing corrosion of main components, and a corrosion-resistant member attached to such a fishing reel. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] 1 to 5 are diagrams showing a first embodiment (dual-bearing reel) of a fishing reel according to the present invention.

[0015] The reel body 1 of the double-bearing reel according to this embodiment includes a left side plate 1A, a right side plate 1B, and a spool 3 rotatably supported between both side plates 1A, 1B. In this embodiment, a handle 5 is provided on the right side plate 1B side, and by operating the handle 5 for winding, the spool 3 is driven to rotate via a known winding drive mechanism (right-hand handle type).

[0016] The reel body 1 is equipped with a frame 7 which constitutes left and right side plates 1A, 1B. The frame 7 is integrally formed from a metal material such as an aluminum alloy, with the left frame 7A directly constituting the left side plate 1A, and the right frame 7B, with a cover body 15 attached thereto, constituting the right side plate 1B.

[0017] The frame 7 has a connecting portion that connects the left side plate 1A and the right side plate 1B. In this embodiment, a front connecting portion 7C is provided in front of the spool 3, a rear connecting portion 7D is provided behind the spool 3, and a lower connecting portion 7E is provided below the spool, and these connecting portions are integrally formed with the left frame 7A and the right frame 7B. Note that a reel leg 8 that is attached to a reel seat of a fishing rod is integrally attached to the lower connecting portion 7E (the reel leg may be integrally formed with the frame).

[0018] The left side plate 1A is formed with an annular recess 7a in which the flange 3a of the spool 3 is received. A recess 7b is formed in the central region of the left side plate 1A, and a bearing 10 is disposed within the recess 7b to rotatably support the left end of the drive shaft 3A of the spool 3. A known spool stopper 12 that prevents the spool 3 from rotating in the fishing line reeling direction is also provided within the left side plate 1A. The spool stopper 12 has a slide lever 12a that protrudes from the outer surface of the left side plate 1A, and by sliding the slide lever 12a, the state can be switched between a state that prevents the spool 3 from rotating in the fishing line reeling direction and a state that allows the spool 3 to rotate in the fishing line reeling direction.

[0019] The right frame 7B is formed in a ring shape with a circular opening 7d formed on the handle side to enable removal and insertion of the spool 3. As described above, the right frame 7B constitutes the right side plate 1B by mounting the cover body 15, and various functional parts (components) such as a winding drive mechanism that transmits the rotational drive force of the handle 5 to the spool, a drag mechanism, a clutch mechanism, etc. are accommodated inside this right side plate 1B.

[0020] The drive shaft 3A is inserted and fixed in the center of the spool 3, and its left end is rotatably supported on the left side plate 1A (left frame 7A) by a bearing 10. A bearing 3C is disposed on the right side of the spool 3 for the drive shaft 3A, and a pin 3D is provided axially outwardly thereof to engage and disengage a pinion gear 23 that is axially slidable by a clutch mechanism. The drive shaft 3A axially outward of the position where the pin 3D is provided has a smaller diameter and is inserted through the pinion gear 23.

[0021] A cover body 15 is removably fixed to the right frame 7B, and the right frame 7B and the cover body 15 form the right side plate 1B of the reel body 1. This cover body 15 is formed in a concave shape so as to create an accommodation space S between it and the right frame body 7B, and the various functional parts mentioned above are disposed within the accommodation space S.

[0022] Various functional parts disposed in the accommodation space S will be described below with reference to FIG. As described above, within the storage space S are arranged the winding drive mechanism 20 which transmits the rotational drive force of the handle 5 to the spool 3, the drag mechanism 50 which applies a desired braking force to the fishing line being reeled out from the spool 3, and the clutch mechanism 70 which switches the spool between a winding state and a free rotation state.

[0023] In this embodiment, the storage space S is formed between the cover body 15 and the set plate 16 attached to the cover body 15, and the above-mentioned mechanisms are disposed within this storage space S. That is, when the cover body 15 is removed from the right frame 7B, the winding drive mechanism 20, the drag mechanism 50, and the clutch mechanism 70 are positioned on the cover body 15 side of the set plate 16, and the components of each mechanism are not exposed (they do not scatter even when the cover body 15 is removed from the right frame 7B).

[0024] The set plate 16 is formed in a substantially cylindrical shape with a circular, plate-like support portion 16a and an annular support portion 16b formed on the outer peripheral end of the support portion 16a and protruding toward the spool side. A flange portion 16c is integrally formed with the support portion 16a and extends radially outward from the annular support portion 16b, and the set plate 16 is fixed to the inner surface of the cover body 15 by screwing a plurality of fixing screws 17 into the flange portion 16c toward the cover body side (see FIG. 6). The annular support portion 16b is adapted to be fitted into the inner surface of a circular opening 7d formed in the right frame 7B.

[0025] As shown in Fig. 6, the flange portion 16c has a plurality of cutouts 16d formed partially along the circumferential direction, and the fixing portion 15a formed on the cover body 15 is positioned in the cutout portion. The fixing portion 15a is formed in a plurality of locations from the annular surface of the cover body 15 toward the inside in the radial direction, and each of the fixing portions 15a has a screw hole for fixing. In addition, a fixing hole is formed in the side surface of the right frame 7B at a position corresponding to the screw hole. As a result, the cover body 15 is fixed to the right frame 7B by aligning the screw hole of the cover body 15 with the fixing hole of the right frame 7B and screwing in a set screw 19 from the outside.

[0026] A through hole 16e is formed in the center of the support portion 16a of the set plate 16, and a support portion (annular wall portion 16f) is formed around the through hole 16e so as to protrude toward the spool side. A recess 16g that opens toward the cover body side is formed in a part of the outer circumferential side of the support portion 16a. A pinion gear 23 that constitutes the winding drive mechanism 20 is disposed in the through hole 16e, and a base end portion of a handle shaft 5A that constitutes the winding drive mechanism 20 is disposed in the recess 16g.

[0027] Here, the configuration of the winding drive mechanism 20 will be described. As described above, in this embodiment, the handle 5 that rotates the spool 3 is provided on the right side plate 1B side, and the winding drive mechanism 20 is disposed in the accommodation space S between the set plate 16 and the cover body 15. The winding drive mechanism 20 includes a handle shaft 5A to which the handle 5 is attached, a drive gear 21 rotatably attached to the handle shaft 5A, and a pinion gear 23 that meshes with the drive gear 21.

[0028] The handle 5, which is operated to wind the reel, is attached to the end of the handle shaft 5A, and the handle shaft is rotatably supported in the right side plate by a bearing 25 disposed between the handle shaft and the cover body 15, and a bearing 26 disposed between the handle shaft and the cover body 15 and a recess 16g formed in the right frame 7B. The pinion gear 23 meshed with the drive gear 21 has the drive shaft 3A of the spool inserted therethrough, and is supported so as to be axially slidable relative to the drive shaft 3A. In this embodiment, both sides of the pinion gear 23 are rotatably supported by bearings 27 and 28, respectively. In this case, the bearing 27 is disposed in the through hole 16e of the set plate 16, and the bearing 28 is disposed in a known braking device 29 that is attached to the cover body 15 and abuts against the end face of the drive shaft 3A of the spool to apply a braking force to the rotation of the spool.

[0029] A known one-way clutch 30 is disposed between the handle shaft 5A and the cover body 15, which allows the handle 5 to rotate in the fishing line winding direction and prevents reverse rotation. A known drag mechanism 50 is disposed on the handle shaft 5A, which applies a desired braking force to the fishing line being unwound from the spool 3. The drag mechanism 50 includes a plurality of brake plates 51 disposed in an annular recess 21a formed in the drive gear 21, a ratchet gear 52 fixed to the handle shaft 5A so as not to move in the axial direction and in contact with the drive gear 21, and an operation knob 55 disposed on the handle shaft 5A and which moves in the axial direction when rotated. When the operation knob 55 is rotated, the brake plates 51 are pressed through the inner ring of the one-way clutch 30, and a desired pressing force acts on the drive gear 21 between the handle shaft 5A and the drive gear 21. That is, by rotating the operation knob 55, the pressing force against the brake plate 51 can be adjusted to apply a desired drag force to the fishing line being reeled out from the spool 3.

[0030] In addition, a locking pawl (not shown) can be engaged with the ratchet gear 52, so that reverse rotation of the handle shaft 5 can be reliably prevented in the event that slippage occurs in the reverse prevention function of the one-way clutch 30.

[0031] A known clutch mechanism 70 for switching the spool 3 between a winding state and a free rotation state is provided on the set plate 16. The clutch mechanism 70 includes an operating member 71 that is provided on the right side plate 1B and rotatably supported along the outer circumferential surface, a clutch plate 72 that is rotatably supported on the set plate 16 and rotates with the operation of the operating member 71, and an engagement member 74 that engages with a circumferential groove formed on the outer circumferential surface of the pinion gear 23 and slides the pinion gear 23 in the axial direction by the rotational operation of the clutch plate 71. That is, the pinion gear 23 is slid in the axial direction by operating the operating member 71, and an end 23b of the pinion gear 23 having a non-circular cross section is engaged with and disengaged from a pin 3D provided on the drive shaft 3A of the spool 3, thereby switching between a power transmission state (clutch ON state) and a power interruption state (clutch OFF state). In this case, the ratchet gear 52 and the set plate 16 are provided with a return mechanism that automatically returns the clutch mechanism from the OFF state to the ON state when the handle is operated for winding.

[0032] The cover body 15 is formed with a bulging portion 15A that bulges out in a substantially semicircular shape so as to partially accommodate the drive gear 21 attached to the handle shaft 5A. This bulging portion is attached to the right frame 7B by a screw and is closed by a blocking member 61 formed in a substantially semicircular shape. That is, as described above, when the cover body 15 to which the set plate 16 is attached is attached to the right frame 7B, the bulging portion 15A is closed as it is by the blocking member 61 attached to the right frame body 7B.

[0033] As described above, many components (functional parts) are housed in the right side plate of the reel body 1, and these are supported by the set plate 16 as described above. In this case, many components are made of different materials and are arranged in contact or close proximity to each other. Therefore, if conductive liquid such as seawater or water adheres to the reel body or the reel body is exposed to such an atmosphere, the potential difference causes a flow of electrons, which induces corrosion. For example, in the through hole 16e of the set plate 16, corrosion is likely to occur in the bearing 27 arranged between the support part (annular wall part 16f) protruding toward the spool side and the side part of the pinion gear 23 (such corrosion deteriorates the rotation performance).

[0034] In this embodiment, the corroding member 100, which has a larger potential difference than the potential difference between the set plate 16 and components made of different materials (such as the components of the take-up drive mechanism 20 and the clutch mechanism 70, and attachment members such as fixing screws, etc.), is disposed in a conductive state so as to be detachable from the set plate 16. The corroding member 100 is made of a material with a high ionization tendency, such as zinc, titanium, aluminum, magnesium, etc., and is selected and used depending on the materials of the components.

[0035] By keeping a corroding member made of such a material with a high ionization tendency in contact with a component (set plate 16), even if an electrically conductive liquid such as seawater or water penetrates and generates a flow of electrons, the flow of electrons will occur preferentially in the corroding member 100, causing corrosion, making it possible to effectively prevent corrosion of other components.

[0036] The corroded member 100 of this embodiment is made of a plate-like member (e.g., a zinc plate) and is detachably attached to the spool-facing surface side of the set plate 16. Specifically, as shown in FIG. 6, the corroded member 100 is detachably attached to the flat surface of the support portion 16a of the set plate 16 by a fixing means (a plurality of screws 102), and the corroded member 100 is electrically connected between the set plate 16 and the screws 102. In addition, since the corroded member 100 is disposed inside the right side plate (at a position that cannot be seen from the outside), the corroded member is not exposed and the appearance is not deteriorated. In addition, the corroded member is not damaged by being dropped or hit against another object, and it is possible to perform its function. Furthermore, by removing the cover body 15 from the right frame 7B to expose the set plate 16, the corroded state of the corroded member 100 can be confirmed (the maintenance time can be known).

[0037] Thus, in this embodiment, unlike conventional structures that prevent corrosion of components as much as possible by providing corrosion prevention means to the components themselves or arranging a seal structure to prevent seawater or other water from entering from the outside, the corrosion member 100 that actively promotes corrosion is arranged to prevent corrosion of the components of the fishing reel (corrosion of the main components), improve corrosion resistance, and prevent deterioration of operation. Also, by installing the corroding member 100 and configuring it to actively corrode, it is possible to let the user know to some extent when maintenance of the fishing reel is required depending on the corrosion state.

[0038] In addition, in this embodiment, since the corroding member 100 is formed in a plate shape, the corroding member can be efficiently arranged without requiring a large space. In particular, since the support part (annular wall part 16f) of the set plate 16 is formed in a ring shape so as to protrude, it is possible to effectively suppress corrosion that is likely to occur in the bearing 27 part arranged in the central region. In addition, since the fishing line with seawater or water attached thereto is wound around the spool 3, moisture is likely to enter the inside of the side plate from the flange part which is the edge of the spool. However, since the corroding member 100 is arranged on the side of the set plate 16 facing the spool, it can be effectively corroded and corrosion of the main components can be prevented.

[0039] Furthermore, when the cover body 15 is removed from the right frame 7B by rotating the locking screw 19, the set plate 16 is fixed to the cover body 15, so that it is possible to easily replace only the corroded member 100 without exposing the components of the winding drive mechanism 20, drag mechanism 50, and clutch mechanism 70 mounted inside the cover body 15, thereby improving maintainability.

[0040] FIG. 7 is a diagram showing a modification of the above configuration. In this modified example, the corroding member 100 is formed into a plate-like member and attached to the surface of the support portion of the set plate 16 on the spool side. In such a configuration, it becomes possible to replace the corroding member 100 together with the set plate 16. Also, the corroding member 100 may be removably attached to the support portion 16a, and may be peeled off when replacing it.

[0041] FIG. 8 is a diagram showing an example of the configuration of a fishing reel according to a second embodiment (spinning reel) of the present invention. As long as the corroding member 100 described above is formed with a large potential difference between itself and the component to which it is attached, specifically, a potential difference greater than the potential difference between itself and another component in contact with (close to) that component, its attachment position is not limited and corrosion of the other component can be effectively prevented.

[0042] A reel body 202 of a fishing spinning reel 200 shown in FIG. 8 has reel legs 202A formed thereon to be attached to a fishing rod. A handle shaft is rotatably supported within the reel body via a bearing, and a handle 203 for winding is attached to the end of the handle shaft. The handle 203 has a handle arm 203A and a handle knob 203B at its tip, and is configured so that the handle 203 can be operated for winding by gripping the handle knob 203B. A known driving force transmission mechanism is connected to the handle shaft, and the rotor 210 is rotated in response to the rotation of the handle 203, and the spool 205 is moved back and forth via a known oscillating mechanism.

[0043] The spool 205 is formed from a metal with a light specific gravity, such as aluminum, an aluminum alloy, or a magnesium alloy, or from a synthetic resin material, and has a line winding trunk portion 205a around which the fishing line is wound, and a front flange portion 205b and a rear flange portion (skirt portion) 205c which determine the amount of line wound around the line winding trunk portion 205a in the front-to-rear direction.

[0044] The rotor 210 is provided with a pair of support arms 211, 212 extending axially forward and facing each other at an interval of approximately 180°, and the spool 205 is located between the pair of support arms and driven to reciprocate back and forth. At the tip of each support arm 211, 212, a bail support member 214, 215 is supported so as to be rotatable between a fishing line winding position and a fishing line releasing position. A base end of a semi-annular bail 217 is attached to each bail support member 214, 215, and the bail 217 is rotatable together with the bail support members 214, 215. At the tip of one of the bail support members 15, a fishing line guide device (line roller) 250 is provided to guide the fishing line to the spool.

[0045] In the spinning reel configured as described above, when the handle 203 is rotated, the rotor 210 is rotated via the drive force transmission mechanism, and the spool 205 is reciprocated back and forth via the oscillating mechanism. As a result, the fishing line is evenly wound around the line winding trunk 205a of the spool 205 via the line guiding device 250 of the bail support member 215, which rotates together with the rotor 210.

[0046] In the spinning reel described above as well, the corroded members 100 can be detachably installed at various locations.

[0047] For example, as shown in FIG. 9, it is possible to detachably mount the sensor 110 on the upper surface of the rotor 210 that is driven to rotate. 10, it may be detachably attached to a knob cap 203C of a handle knob 203B provided at the tip of the handle arm 203A by using a screw 110. Alternatively, although not shown, it may be detachably attached to an arbitrary position inside the handle arm 203A (a position that is difficult to see from the outside). 11, it is also possible to remove a known rear cap 230 attached to the rear end of the reel body 202, and detachably mount the corroding member 100 inside the opening of the reel body (inside the rear cap). Furthermore, it is also possible to attach a corroding member to the inner surface of the rear cap 230 (inside the rear cap), and then replace the rear cap 230.

[0048] Furthermore, the corroding member 100 may be detachably attached to the reel leg 202A that is attached to the reel leg fixing portion of a fishing rod, or to the sole of the reel leg 8 of the double-bearing type reel shown in FIGS.

[0049] As described above, the corroded member 100 can be installed in various locations, such as inside the reel body, the handle, the reel legs, and even the fishing line guide device, and the shape and mounting direction of the corroded member can be modified in various ways depending on the installation location.

[0050] In this way, by attaching the corroding member to any of the components of the reel, it is possible to effectively suppress corrosion that occurs between that component and other components that are in contact with it (including in close proximity to it). For example, it is possible to effectively suppress corrosion in various functional parts that make up the drive force transmission mechanism and the oscillating mechanism, and in the fixing members (screws, rivets, etc.) that connect the components together.

[0051] Next, a description will be given of the results of an experiment conducted on the changes in the constituent members of a fishing reel having the above-mentioned corroded members when the fishing reel was continuously immersed in seawater.

[0052] Figure 12 is a photograph showing the changes that occur when a corroded part (made of ZDC plate, a zinc alloy for die casting, the circled part) is attached with screws to the surface of the spool side of the set plate and then immersed in seawater. The plate was immersed in seawater for one hour continuously, and this process was repeated seven times. As a result, white deposits (unevenness) were observed on the surface of the ZDC plate, which was the corroded component, and corrosion had occurred.

[0053] FIG. 13 is a photograph showing the protruding portion of a conventional SUS handle shaft, which is a component that is in contact with the set plate, and the anodized drag knob that is attached to it. (a) shows a configuration in which the corroding member shown in Figure 12 is not provided on the set plate, and (b) shows a configuration in which the corroding member shown in Figure 12 is attached to the set plate. As with Figure 12, both show the state after being immersed in seawater for one continuous hour, and this was repeated seven times.

[0054] As can be seen from these comparative photographs, when the corroding member was attached to the set plate, the corroding member corroded, but corrosion did not progress to the main components.

[0055] Figure 14 is a photograph showing the results of an experiment comparing a handle arm with a corroded material attached to the inside of its base end (the part attached to the handle shaft) with one that was not. The handle arm is made of aluminum alloy (A6061) that has been anodized, and the handle knob is fixed to the tip end of the handle arm by crimping it with a stainless steel rivet.

[0056] The left side of (a) has an aluminum plate (black) with an anodized base end to prevent the nut from loosening, and the right side of (a) has a zinc plate (white) of the same shape. These two handle arms were sprayed with seawater for three weeks. When the aluminum plate was inserted, corrosion occurred around the SUS rivets (left side of (b)), whereas the zinc plate was inserted and no corrosion was observed around the SUS rivets (right side of (b)).

[0057] Although aluminum has a greater tendency to ionize than zinc, it is believed that the area through which electricity flows is reduced when the aluminum is anodized as described above, and therefore it is believed that the effect was obtained even when the zinc plate described above was attached.

[0058] As in the above-described embodiment, the present invention is characterized in that a corroded part can be attached and detached to the inside of the reel body of a fishing reel or to the surface of a component exposed to the outside of the reel body (preferably in a position that is not visible), and when corrosion of the corroded part progresses, maintenance work can be performed to replace it with a dedicated corroded part. For this reason, the present invention includes a corroding member that is detachable from a portion where components made of different materials are arranged in contact or close proximity to each other and is made of a material that produces a potential difference greater than the potential difference between the components made of different materials. Such a corroding member can be manufactured and sold as a replacement part (dedicated product), and its shape can be specified according to the mounting position and mounting method, and it can be made into a shape other than a plate shape, such as a block shape, or a shape that has some function.

[0059] In addition, by forming such a corrosion member into a zinc plate, it becomes possible to improve workability and reduce costs.

[0060] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways. In addition to the above-mentioned types of fishing reels, the present invention can be applied to various types of reels such as electric reels and single-bearing reels, and the mounting position can also be changed in various ways. Also, since corrosion is not limited to contact between metal members, but can occur between dissimilar materials such as carbon and aluminum, it is only necessary to mount an optimal corrosion-resistant member taking into consideration the potential difference that occurs between the constituent members.
