2. Description of the Related Art Fishing supplies include fishing reels such as spinning reels and dual-bearing reels. The surface of the reel body of the fishing reel is usually coated or plated to improve decorativeness and corrosion resistance. Processing has been applied. Synthetic resin or aluminum alloy is used for the reel body in order to reduce the weight. A coating process is applied to the synthetic resin reel body, and a coating process or plating process is applied to the aluminum alloy reel body. .

[0003]

In the conventional treatment, the entire surface is uniformly plated. Therefore, for example, a high-precision portion such as a screw portion or a fitting portion for mounting another component on the reel body is subjected to the same plating treatment as the other portion. Then, even if a high-precision part is processed in the material, the dimensions change due to the plating process, and rework or the like for improving accuracy is required.

[0004] It is an object of the present invention to provide a fishing gear with a surface structure, particularly when a member such as a reel body is subjected to plating, without impairing the accuracy of the high precision portion.

According to a first aspect of the present invention, there is provided a fishing gear having a surface structure formed of a metal material having a high-precision part for mounting other parts, and a thickness of 15 μm or less on the material part. And a second plating layer formed on the first plating layer excluding the high precision part. In this case, since a very thin plating base layer is formed in the high-precision portion, a change from the finished dimension of the material can be reduced and high accuracy can be maintained. In addition, by performing plating on the high-precision part, rust is less likely to occur. On the other hand, since the members excluding the high-precision portion are provided with the first plating layer and the second plating layer, the corrosion resistance is further improved.

A surface structure of a fishing gear according to a second aspect of the present invention is the surface structure according to the first aspect, wherein the raw material portion of the fishing gear is formed of an aluminum alloy member. In this case,
The processing of the material part is easy and lightweight. The surface structure of a fishing gear according to a third aspect of the present invention is the surface structure according to any of the first or second aspects, wherein the first plating layer for the base is formed by an electroless plating method, and the first plating layer is located closer to the surface than the first plating layer. The formed second plating layer for decoration is formed by an electroplating method. In this case, the first plating layer can be formed as a thin film. In addition, the second plating layer can be formed by an easy method generally using a versatile electroplating method.

The surface structure of a fishing gear according to a fourth aspect of the present invention is the surface structure according to any one of the first to third aspects, wherein the second plating layer comprises a plurality of nickel plating layers. In this case, the surface of the second plating layer is less likely to rust and has a good gloss. Further, the corrosion resistance is improved.
The surface structure of a fishing gear according to a fifth aspect of the present invention is the surface structure according to any one of the first to fourth aspects, further comprising a chromium plating layer formed on the second plating layer. In this case,

[0008]

1 and 2, a dual-bearing reel adopting an embodiment of the present invention is a low-profile type reel for bait casting. The dual-bearing reel is rotatably and detachably mounted inside the reel body 1, a spool body 2 made of an aluminum alloy, a spool rotating handle assembly 2 arranged on the side of the reel body 1. And a spool 4 for thread winding. A star drag 3 for drag adjustment is provided on the reel body 1 side of the handle assembly 2.

The reel body 1 has a frame 5, side covers 6 mounted on both sides of the frame 5, a front cover 7 covering the front of the frame 5, and a thumb rest 8 covering the upper part. Each member constituting the reel body 1 is made of an aluminum alloy, and the surface of each member is subjected to a plating process using a tunnel etching method. Note that a high-precision portion such as a screw portion to which the cascon knob 9 is screwed is subjected to a plating process different from other portions.

Further, a semi-glossy portion is formed on a part of the side cover 6 and the thumb rest 8 by a matting process. That is, as shown by a broken line in FIG. 1, semi-glossy portions 6a, 6b, 6c are formed in a part of the side cover 6, and portions not shown by the broken line are glossy portions 6d. The semi-gloss part 6a is formed in the lower part of the side cover 6 so as to extend in a band shape in the front-rear direction. Semi-gloss part 6
b and 6c are formed on the upper part of the side cover 6 so as to extend in a band-like manner from the front end to the length in the front-rear direction. The side cover not shown in FIG. 1 also has a semi-gloss part and a gloss part. The detailed configuration of the semi-gloss part will be described later. The thumb rest 8 has a semi-glossy portion similar to that described above over the entirety thereof.

Next, the surface structure of each member constituting the reel body 1 will be described in detail. As shown in FIG. 3, an underlayer 1 is formed on the surface of each member by a tunnel etching method.
0 is formed. By performing a surface treatment on each member made of an aluminum alloy by a tunnel etching method, minute pits P are formed on the surface as shown in an enlarged manner in FIG. An electroless nickel plating layer 11 and a double nickel plating layer 12 are sequentially formed on the underlayer 10. Further, a chromium plating layer 13 is formed on the double nickel plating layer 12.

The tunnel etching method is a method in which a material (aluminum) is strongly etched with a pulse power supply while being immersed in a hydrochloric acid bath, and a mechanical anchor effect is produced by electroless nickel applied on the surface. In this case, minute pits P are formed on the surface of the member as described above, and the electroless nickel plating layer 11 can be firmly adhered.

Next, the surface structures of the semi-glossy portions of the side cover 6 and the thumb rest 8 will be described. As shown in FIG.
In the side cover 6, a base layer 10 is formed on the surface of the material by a tunnel etching method, and an electroless nickel plating layer 11 and a double nickel plating layer 12 are sequentially formed thereon. Here, a part of the surface of the double nickel plating layer 12 (the part corresponding to the semi-glossy portions 6a, 6b, 6c or the entirety of the thumb rest 8) is subjected to a matting process by a glass bead shot process. A chromium plating layer 13 as a final plating layer is formed so as to cover the entire matted portion and the uncoated portion.

Conventionally, when a semi-gloss part is formed,
Although the glass bead shot processing is applied to the material before the plating processing, since a plurality of plating layers are formed on the raw material, the matting effect is lost and no contrast is obtained. However, in this embodiment, since the glass bead shot processing is performed immediately before the plating processing of the chromium plating layer 13, a matte effect appears, and a shiny appearance can be obtained.

Next, the surface structure of a high-precision portion such as a screw portion of the member constituting the reel body 1 will be described. If the underlayer 10 formed by the tunnel etching method is formed on the surface of the high-precision portion such as the screw portion, and a plurality of plating layers as described above are formed, even if the material is formed with high precision, the plating layer Desired dimensions may not be obtained depending on the thickness.
Therefore, as shown in FIG. 5, the underlayer 10 is formed by the tunnel etching method, and the electroless nickel plating layer 11 is formed thereon, as shown in FIG.
Further, no other plating layer is formed thereon. Note that the thickness of the electroless nickel plating layer 11 in the high precision portion is set to 15 μm or less. The plating process other than the high-precision portion is the same as described above. A double nickel plating layer 12 is formed on the electroless nickel plating layer 11, and a chromium plating layer 13 is further formed thereon.
In the plating process of the portion including such a high-precision portion, first, the base layer 10 and the electroless nickel plating layer 11 are formed entirely. Next, when the high-precision part is a screw part, a nut 15 is attached to the screw part as shown by a two-dot chain line in FIG.
2 and a chromium plating layer 13 are formed. As a result, only the base layer 10 and the electroless nickel plating layer 11 are formed for the screw portion, and the double nickel plating layer 12 and the chromium plating layer 13 are formed on the other portions in this order.

Here, since the thickness of the plating layer in the high-precision portion is small, the dimensions of the material do not greatly change. In addition, since the electroless nickel plating layer 11 is formed in the high-precision part, the corrosion resistance is not impaired. [Other Embodiments] In the above embodiment, with regard to the plating treatment of the reel body made of aluminum alloy, the underlayer 10 is formed on the surface of each member of the reel body by the tunnel etching method. May be used. In this case, it is a method which has been conventionally used well, and the plating treatment is easy.
