A spacer 20 consisting of the insulator, such as synthetic resin, is interposed between the main body 3 and the cover 4 as well as the cap 21. A water repellent material, such as tetra(tri)fluorochloroethylene resin, is applied on the externally exposed parts of these joint parts to form coating films 32, by which the adhesion of the sea water, etc., to the externally exposed parts is prevented. Even if the sea water, etc., adhere to the reel, the insulation characteristic is assured and, therefore, the two parts varying in the electrolytic solution pressures conduct each other and there is no possibility that the electrochemical corrosion occurs.

2. Description of the Related Art Electrolytic pressure (sometimes referred to as electrode potential).
When two kinds of metals, typically, an anode material such as aluminum material and magnesium material and a cathode material such as iron and copper are left in an aqueous electrolytic solution, a metal having a high electrolysis pressure is dissolved. It is known that electrochemical corrosion occurs.
Therefore, in the case of industrial equipment and the like, when adopting a configuration in which two parts having different electrolysis pressures are combined, electrochemical corrosion is prevented by interposing an insulator made of a synthetic resin or the like between the two parts.

[0003]

In recent years, in fishing gear such as fishing reels and fishing rods, an anode-side metal such as an aluminum material or a magnesium material has been frequently used in order to make the product tougher and lighter. However, like general industrial equipment,
If only an insulator is interposed between these materials and another material having a different electrolysis pressure, there is a problem that seawater or the like as an electrolytic aqueous solution adheres and electrochemical corrosion cannot be sufficiently prevented.
For example, when seawater or the like attached to the fishing line at the time of winding the fishing line, seawater due to waves, rainwater or the like containing the same adheres to the outer surface of the fishing tackle, two components having different electrolysis pressures pass through the seawater or the like. Conducts and causes electrochemical corrosion.

[0004] It is an object of the present invention to provide an electrochemical corrosion prevention structure for a fishing tackle in which electrochemical corrosion hardly occurs even when an electrolytic aqueous solution such as seawater adheres.

[0010]

1 and 2 show a fishing spinning reel to which the present invention is applied. A housing 1 of the reel is provided with a main body 3 having a mounting leg 2 to a rod tube and a cover plate 4. A rotor rotating barrel 6 is rotatably mounted on the front part of the main body 3 via a bearing 5 around its axis. A rotor 8 is connected to a front end of the main body 3 via a nut 7 so as to be integrally rotatable. A handle 9 is arranged on the side of the main body 3, and the handle 9 is attached to the main body 3 by a pair of bearings 10,
It is connected to the handle shaft cylinder 11 supported through the support 10. When the handle 9 is rotationally driven, the rotation is transmitted to a pinion 13 formed on the rear end side of the rotor rotary barrel 6 via a handle barrel 11 and a drive gear 12 formed integrally therewith. As a result, the rotor rotary barrel 6 is driven to rotate about its axis together with the rotor 8.

The spool shaft 1 is located at the center of the rotor shaft barrel 6.
4 is slidably inserted in the axial direction, and a spool 15 and an oscillator 16 are attached to its front and rear ends, respectively. The oscillator 16 is engaged with a traverse cam shaft 17 extending in the front-rear direction (the left-right direction in FIG. 1). The traverse cam shaft 17 is supported by the reel housing 1 so as to be rotatable around its axis by spacer bushes 18, 18, and is provided so as to be rotatable about its axis in conjunction with the rotation of the handle shaft cylinder 11. The rotation of the traverse cam shaft 17 drives the oscillator 16 in the front-rear direction. As a result, the spool 15 is reciprocated in the front-rear direction via the spool shaft 14. A cap 21 is attached to the rear end of the main body 3 via a spacer 20 and fixed with screws 22.

In the above-mentioned reel, for example, when the main body 3 and the lid 4 of the housing 1 are formed of an anode-side metal such as aluminum or magnesium, electrochemical corrosion can be prevented by the following configuration. .

A) When the cap 21 is formed of a metal such as stainless steel on the cathode side, the spacer 20 is formed of an insulating material, and the main body 3 and the cover 4 are formed.
A spacer 20 formed of an insulator such as a synthetic resin is interposed between the cap 21 and a water-repellent material such as ethylene tetrafluoride chloride or ethylene trifluoride chloride resin on the externally exposed portions of these joints. The coating is applied to form a coating film 32 to prevent seawater or the like from adhering to the externally exposed portion.

B) Bearing 5 for supporting rotor rotating barrel 6
Is formed of a metal such as stainless steel on the cathode side,
A water-repellent resin paint is applied to the inner surface of the mounting hole of the bearing 5 to form an insulating coating film 32. Then, the bearing 5 is mounted via the coating film 32. In this case, tetrafluoroethylene chloride,
What is necessary is just to apply what mixed the water-repellent raw material, such as the polymer of trifluoroethylene chloride or silicone resin, with the resin paint which has insulation.

C) Bearing 1 for supporting handle barrel 11
When 0 is formed of a cathode-side metal such as stainless steel, a spacer 31 impregnated with a water-repellent material is attached to the mounting hole of the bearing 10, and the bearing 10 is mounted via the spacer 31. As an example of the impregnation method, as an example, the material of the spacer 31 is immersed in a dispersion containing fine particles of a polymer of tetrafluoroethylene chloride or ethylene trifluoride, a binder and a dispersion, or a solution of these polymers. At this time,
By performing at least one of decompression and pressurization of the environment in which the dispersion liquid or the like is installed, the penetration of the water-repellent material into the material of the spacer 31 can be promoted.

D) When the traverse cam shaft 17 is made of a metal such as stainless steel on the cathode side, the traverse cam shaft 17 is interposed between the traverse cam shaft 17 and the main body 3.
The spacer bushings 18 and 18 (see FIG. 1) for supporting the above have insulation properties, and the bushing 18 contains ethylene tetrafluoride chloride or ethylene trifluoride chloride polymer. As an example, the spacer bush 18 is formed by mixing the above polymer fine particles into an insulating material for forming the spacer bush 18.

E) A coating film 33 (shown by hatching in FIG. 1) is formed by applying an acrylic silicone resin paint on the mounting surface of the reel mounting leg 2 of the housing 1 with respect to the reel sheet (not shown). As a result, even when the reel sheet is made of a cathode-side metal such as stainless steel, the cathode-side metal reel sheet and the reel mounting leg 2 are insulated by the coating film 33. When the acrylic silicone resin coating film 33 is used, the wear resistance is improved as compared with the fluorine resin coating film 32.

Next, when the rotor 8 is formed of a cathode-side metal such as brass, electrochemical corrosion is prevented by the following configuration.

F) A coating film 34 is formed by applying a silicone resin paint to the mating surface of the rotor 8 with at least one of the rotor shaft barrel 6 and the nut 7.
4 and the rotor 8 is assembled. When the silicon coating film 34 is formed, the abrasion resistance is improved as compared with the fluorine resin coating film 32.

According to the above construction, even if an aqueous electrolytic solution such as seawater adheres to the reel, the aqueous solution is coated with the coating films 30, 32,
33, 34, the spacer 31 and the spacer bush 18 are repelled by water repellency and have different electrolysis pressures, that is, between the main body 3 or the lid 4 and the cap 21, the bearings 5, 10, or the traverse cam shaft 17. Insulation between the mounting leg 2 and the reel seat, or between at least one of the rotor shaft barrel 6 and the nut 7 and the rotor 8 is ensured. Therefore, there is no possibility that two components having different electrolysis pressures will conduct to cause electrochemical corrosion. . In each of the above examples,
As the water-repellent material, fluorine, silicon, or acrylic silicon can be appropriately selected as needed, and other various water-repellent materials can be used instead. The position where the water repellent treatment is performed is not limited to the above a to f, and the present invention can be applied to any combination of two parts having different electrolysis pressures. The spacer 31 and the spacer bush 18 may be entirely impregnated or impregnated with a water-repellent material, or may be applied, contained, or impregnated only on an externally exposed portion. The method of impregnating or containing the water repellent material is not limited to the above example, and various methods may be used. As an example, various methods used for water-repellent treatment of the inner surface of the hollow rod can be used. In the drawings, the thicknesses of the coating films 30, 32, 33, and 34 are exaggerated.

The present invention is not limited to spinning reels, but can be applied to various fishing gears combining two parts having different electrolysis pressures. For example, in the case of a dual-bearing reel, the present invention can be applied to a bearing portion of a spool shaft or a traverse cam on the frame body, a mounting portion of a conductive ring of a magnetic brake on the spool shaft, or the like. In the case of a fishing rod, for example, a female screw holder made of an anode-side metal material such as an aluminum material fixed to the base end of the original rod, and a cathode side such as a stainless steel material screwed to the female screw holder are used. Applicable to buttocks made of metal materials.

The two components having different electrolysis pressures are not limited to those made of so-called anode-side metal and cathode-side metal, respectively. If the electrolysis pressure differs between the anode-side materials or between the cathode-side materials, electrochemical corrosion may occur. Therefore, it is desirable to apply the present invention to impart insulation and water repellency between these two parts.

[0023]

According to the first aspect of the present invention, the insulator interposed between the two components having different electrolysis pressures has water repellency.
Even if seawater or the like splashes on the outer surface of the fishing gear, the water droplets are repelled without remaining between the two parts. Accordingly, there is no possibility that an electrolytic aqueous solution such as seawater adheres or permeates between the two parts, and both parts are reliably insulated by the insulator, thereby preventing electrochemical corrosion.

According to the second aspect of the present invention, the water-repellent material applied between the two parts repels water, such as seawater, so that the two parts are insulated. Therefore, there is no need to interpose a separate insulating component between the two components, so that the labor required for manufacturing and assembling such an insulating component is eliminated, and the manufacturing process of the fishing tackle is simplified. Inventories and management of insulating parts are not required.

According to the third aspect of the present invention, a water-repellent material is mixed into a material of the insulating component when the insulating component is manufactured, or the manufactured insulating component is immersed in the water-repellent material. Thus, when assembling the fishing tackle, it is only necessary to interpose the obtained insulator between two parts having different electrolysis pressures. Therefore, the assembling work can be simplified. Since the insulating component contains or impregnates the water-repellent material, the water-repellent function can be maintained for a long time.

According to a fourth aspect of the present invention, a water-repellent material is applied to the externally exposed portion of the insulator before the insulator is assembled, or the water-repellent material is applied to the externally exposed portion after the insulating component is assembled between the two components. It is possible to prevent electrochemical corrosion between the two parts simply by applying, and there is an advantage that it is not necessary to largely change the manufacturing process of the conventional fishing tackle.
