[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In a dual-bearing reel for fishing according to the present invention, a frame and / or a handle side plate constituting a reel body are made of an Mg alloy, and an anticorrosion layer is formed on the surface thereof. Spool outer diameter size is 30
Up to 50 mm and the height of the reel body is 40 to 70 m
m.

In the present invention, the Mg alloy includes A
An alloy containing l, Zn, Mn, or the like as an alloy element can be given. Further, in the fishing dual-bearing type reel of the present invention, the reel constituting members such as a frame constituting the reel body and a pair of side plates on both sides thereof are formed by, for example, a die casting method using a Mg alloy or a thixo molding method. It is preferred that

As the die casting method, a cold chamber method or a hot chamber method which is usually performed can be employed. In particular, because the manufacturing cycle is fast,
It is preferable to use a hot chamber method.

In order to adjust the surface of the reel component, a mechanical surface treatment such as grinding, shot blasting and barrel polishing, and a chemical surface treatment such as solvent cleaning, alkali cleaning and pickling are applied to the main body of the member. May be applied.

In the present invention, the method of forming the anticorrosion layer includes chromic acid treatment, heavy chromate treatment, zinc phosphate treatment, manganese treatment, non-chromium / manganese treatment, stannate treatment, etc., painting, anode Oxidation treatment and the like can be mentioned. In particular, as the anodizing treatment, a HAE anodizing treatment and a Dow17 anodizing treatment capable of forming a dense anodized film can be used.

These anodic oxidation treatments are carried out with dense and hard Mg
Since an anodic oxide film having a spinel structure, which is a complex oxide structure, is formed with O, extremely excellent corrosion resistance can be imparted to the components of the fishing reel.

As a more excellent anodic oxidation method, there is a high voltage anodic oxidation treatment (for example, MAGOXID treatment). This high-voltage anodizing treatment is performed by applying a high voltage (for example, 20 μm) in an organic aqueous electrolyte (for example, sulfuric acid, phosphoric acid, aluminate, etc.).
(0 V or more).

The features of this method are the Dow 17 method and the HAE
Compared with the conventional anodic oxidation method such as the method, the coating composition contains more MgO components than spinel, so that corrosion resistance, abrasion resistance and adhesion are good. For this reason, scratches that reach the material are unlikely to occur, and contact corrosion with dissimilar metals is less likely to occur.

That is, an electrochemical corrosion test (DINSS5)
0918) and neutral salt spray test (DIN 5002)
After performing 1), according to the high voltage anodic oxidation method, Do
Compared to conventional anodic oxidation methods such as w17 method and HAE method,
It shows much better corrosion resistance, and abrasion test (rubber test) and adhesion test (punch test) were performed. The high voltage anodization method was replaced by the conventional anodization method such as Dow17 method and HAE method. In comparison, it showed much better wear resistance and adhesion.

Further, since the anticorrosion layer formed by anodic oxidation contains a large amount of MgO component that develops white, the appearance after the treatment becomes beautiful white, and without overcoating such as metallic coating.
A high quality appearance can be obtained only by performing the sealing treatment. Furthermore, since the base is white, it can be dyed in various colors with dyes and pigments.

The thickness of the film (corrosion protection layer) formed by the anodic oxidation treatment is preferably from 5 to 20 μm, which shows stable performance (hard and dense). This is because if the thickness of the coating is less than 5 μm, the hardness of the coating is not sufficient,
If the thickness exceeds 20 μm, cracks may occur in the process of growing the film.

It is preferable that the thickness of the portion of the anodic oxide film that is in contact with or in proximity to the dissimilar metal component is thicker than other portions. For example, the thickness of a portion other than the portion where the dissimilar metal component contacts is set to 5 to 20 μm, and the thickness of the portion where the dissimilar metal component contacts is set to 10 to 20 μm.

It is preferable to design the contact at the time of the anodic oxidation treatment at a portion where there is no possibility of corrosion. this is,
This is because the thickness of the anodic oxide film at the joint of each member is reduced.

In the present invention, the sealing layer is preferably formed of an organic substance or ceramic. As the sealing method, it is preferable to use impregnation, diffusion treatment, sol-gel treatment, electrodeposition coating, or spray coating of a low-viscosity paint.
These processes can close small holes and fill small recesses, so that changes in dimensions can be ignored.

Examples of the organic material constituting the sealing layer include epoxy, urethane and acrylic resin paints. Among them, epoxy and acrylic paints are preferable because they have good adhesion to the anodic oxide film and the coating film is dense.

The resin impregnation as a sealing method is performed by placing a container in which a resin solution is accommodated, in which a member to be processed is immersed, in a vacuum furnace, and reducing the pressure in the vacuum furnace (for example, to 5 mmHg). By applying pressure (for example, 5 to 6 kgf / cm ² ), the member to be treated is impregnated with a resin, and then dried at 80 ° C.

The low-viscosity paint used in the spray coating means a paint having a sufficiently low viscosity to close the pores of the anticorrosion layer, which is an anodic oxide film, and to further fill the recesses. Therefore, the viscosity is appropriately adjusted depending on the thickness and surface condition of the anodic oxide film. Examples of the method for adjusting the viscosity include a method for adjusting the material ratio in the paint.

The ceramics constituting the sealing layer include:
Examples thereof include silica and titanium oxide. Among these, the impregnation treatment with low molecular weight polysilazane can fill small holes and recesses with silica at a low temperature,
Since there is almost no unsealed portion, high corrosion resistance can be obtained. For example, the impregnation of ceramics as a sealing method is performed by immersing a member to be treated in low molecular weight polysilazane, impregnating the member using a capillary phenomenon, and then performing impregnation by about 2 hours.
It can be carried out by drying at 00 ° C.

The thickness of the sealing layer is 5 to 20 μm which shows stable performance (good adhesion to the anodic oxide film and dense).
m is preferable. This is because the film thickness is 5 μm
If it is less than 1, the damage of the sealing layer reaches the anodic oxide film, and the anticorrosion effect is reduced, and if it exceeds 20 μm, the shrinkage when the paint is hardened is large, and the adhesion to the anodic oxide film is reduced. It is.

In the fishing reel of the present invention, the sealing layer may be coated as required. In addition, the sealing layer may have a decorative property when formed, and the sealing layer may exhibit the decorative property.

Further, in the fishing reel of the present invention, the winding state of the fishing line when the fishing line is wound on the spool 6a by the level wind device 38 as described above has an influence on the reeling operability at the time of reeling out the fishing line. Technical considerations not to give are given.

The dual-bearing type reel 1 configured as described above
, The reel body 4 including the frame 2 and the left side plate 3a is made of Mg containing 3.5 to 9.7% by weight of Al.
It is formed by molding an alloy by a die casting method using a hot chamber. Also, the reel body 4
Has a structure in which an anticorrosion layer is provided on the surface and a sealing layer is further provided on the anticorrosion layer.

For the anticorrosion layer, the frame 2 and the left side plate 3a, which are in contact with each other, are put into a processing solution adjusted with potassium hydroxide, potassium fluoride, sodium phosphate, aluminum hydroxide, potassium permanganate, etc. It is formed by performing HAE anodic oxidation treatment under the condition of passing electricity for a certain period of time. The sealing layer is formed by performing electrodeposition coating using an epoxy paint. The sealing layer is formed in a state in which the paint is filled in the pores and recesses of the anodic oxide film constituting the anticorrosion layer. Further, since this sealing layer is formed by electrodeposition coating, its surface is flattened.

It can be used without trouble even in fishing methods in which the discharging and winding operations are frequently repeated for a long time, and in use under severe conditions.

In particular, because of its light weight, small size, and sufficient strength, during actual fishing, the operation of continuously releasing, winding, and gripping the fishing line can be smoothly and reliably performed. It is possible to further improve the operability of fishing.

Further, when the corrosion resistance of the fishing reel according to the present embodiment was examined by a salt spray test, no corroded portion was visually observed, and the corrosion resistance was equivalent to that of the conventional aluminum reel. It was found to show very good corrosion resistance.

The very excellent corrosion resistance is shown by the fact that the anticorrosion layer is composed of an anodic oxide film having a dense spinel structure, the sealing layer has excellent adhesion to the anodic oxide film, and This is considered to be because a dense epoxy coating film was used, and the epoxy coating film was filled in the holes and recesses of the anodic oxide film.

The appearance is the silver color of the chemical conversion film,
The harmony with the transparency and gloss of the silica in the sealing layer resulted in a dignified appearance of the metal as it was.

The outer diameter of the spool is 30-50mm and the height of the reel body is 40-70mm, so it is lightweight and small. In addition, excellent proof stress and operability can be obtained, and even if the fishing line is repeatedly used for winding and releasing operations for a long time, the fishing operation can be performed comfortably with little fatigue.

In other words, a series of continuous fishing operations such as releasing and adjusting the fishing line, fighting with the fish, winding the fishing line, etc. can be performed quickly and reliably while preventing practical functional troubles. Furthermore, since the Mg alloy has a good thermal conductivity, it does not feel cold when gripped and held by hand, is easy to fit into the hand, and has excellent holding properties.

In particular, when applied to a baitcasting reel or the like in the form of a reel that holds the palm of a hand and discharges a gimmick to a desired point, a fishing line which is an indispensable performance particularly required for this type of reel is provided. Release characteristics,
It is possible to improve the fishing line winding characteristics and the grip holding performance, and the fishing characteristics are further improved.

Particularly, when the frame is made of Mg alloy, the spool is brought into contact with the inner periphery of the spool insertion hole and the outer periphery of the spool due to the occurrence of bending during winding under heavy load, and the gear of the winding drive mechanism is rotated. Can reliably be prevented such as a decrease in the meshing performance. Furthermore, by forming the handle side plate from an Mg alloy, even with heavy load winding, by cooperating with the frame,
It is sufficiently reinforced in terms of strength, and can be used without trouble even under severe conditions, and durability is further improved.

Further, since the anticorrosion layer is formed on the surface of the frame and / or the side plate on the handle side, it is possible to obtain corrosion resistance that can be practically used even in a fishing environment in a harsh environment where seawater or water easily adheres.
