2. Description of the Related Art Fishing supplies include fishing reels such as spinning reels and double-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. .

When plating a reel body made of an aluminum alloy, first, the surface of the reel body is zinc-substituted, and a first plating layer is formed on the surface. Further, a second plating layer is formed on the surface of the first plating layer by nickel plating or the like.

[0004]

The reason why the zinc substitution method is used for plating a reel body made of an aluminum alloy is that a nickel plating layer cannot be directly formed on a reel body made of an aluminum alloy. However, when the plating treatment is performed using the zinc substitution method, the corrosion resistance of the first plating layer and the second plating layer is significantly reduced if the first plating layer and the second plating layer are greatly damaged due to the poor corrosion resistance of zinc itself. Also, the zinc substitution method is sensitive to heat,
The zinc substitution method cannot be used for a portion that becomes hot due to friction or the like.

An object of the present invention is to obtain a surface structure of a fishing gear by plating without using a zinc substitution method.

Means for Solving the Problems The surface structure of the fishing gear according to the first aspect of the present invention comprises a metal material portion having a surface formed with an anchor hole, a first plating layer for a base formed on the material portion. And a second plating layer for decoration formed on the surface layer side from the first plating layer. In this case, since fine pits are formed on the surface of the metal material part by a tunnel etching method or an acid electrolysis method instead of the zinc substitution method, the metal material part and the plating layer on the surface are not Has improved adhesion. Therefore, the corrosion resistance is also improved. Here, a process of forming pits on the surface of the material portion by a tunnel etching method, an acid electrolytic method, or the like in order to improve the adhesion of the plating layer to the material portion is referred to as an anchor hole forming process.

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 with 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 structure of the semi-glossy portion 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-glossy portion 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 lower soil 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 part is small, the dimensions of the material do not change significantly. In addition, since the electroless nickel plating layer 11 is formed in the high-precision part, the corrosion resistance is not impaired.
