There is a widely known method of inviting other large fish by showing a form in which a living small fish is swimming underwater. FIG. 3 shows a conventional artificial bait apparatus used for this type of fishing, in which a hollow portion 14 extending from the head 12 side to the tail 13 side is formed in a main body 11 resembling the outer shape of a fish. The guide wire 18 is longitudinally inserted into the hollow portion 14.
And a spherical weight 15 inserted through the guide wire 18 is movably incorporated, and a magnet 16 made of ferrite such as isotropic barium ferrite is provided on the head 12 side of the hollow portion 14. The fishing line is provided so that the fishing line is inserted into a hardware 17 attached to the head 12.

なる。In such a pseudo bait device, first, acceleration is applied during casting, whereby the weight 15 is separated from the magnet 16 by inertia force and moves to the tail 13 side as shown by a dotted line in the figure. Thereby, since the pseudo bait apparatus flies with the tail 13 side having a small air resistance at the head, a larger flight distance can be obtained as compared with the case of flying with the head 12 side at the head. Further, after landing, the fishing line is turned, so that the head 12 side comes first, and the weight 15 moves in the hollow portion 14 by the magnetic force of the magnet 16, and as shown by a solid line in the figure, the magnet 16 Magnetically. As a result, when the center of gravity of the pseudo bait device moves to the head 12 side and the fishing line is pulled, the pseudo bait device moves to the tail 13
Shake to show the appearance of a small fish swimming.

によって形成された鋼球が使用されていた。[0004] As described above, since the pseudo bait device eccentricizes the center of gravity of the pseudo bait device by moving the weight 15 in the hollow portion 14 by the inertial force or the magnet 16, It is necessary to use a material having magnetization and a specific gravity. For this reason, in the conventional artificial bait apparatus, a steel ball formed of mild steel is generally used as the weight 15.

There has been a problem that the distance cannot be obtained or the tail 13 swings insufficiently in water after landing. Therefore, as shown in FIG. 4, two weights 15, 15 are arranged in series in the hollow portion 14, and the weight is replenished to improve the flight distance and the tail swing operation. Is used. Even if two weights 15 are connected in this manner, in the case of the steel ball weight 15, since the magnetizing force is strong, the weight 15 on the side away from the magnet 16 can also be magnetized.

のである。Further, the present applicant has already obtained a weight 15 made of a W—Ni—Fe-based material which can obtain a higher specific gravity than the steel ball weight 15 and does not have an excessive magnetizing force.
(Japanese Patent Application No. 10-223806). This is because the weight is made of a sinter having a composition comprising 3 to 15% by weight of Ni and 4 to 15% by weight of Fe as a binder phase forming component, and the balance consisting of W as a dispersed phase forming component and inevitable impurities. It is formed by an alloy. The binder phase-forming component contains 3 to 15% by weight of Ni, 4 to 15% by weight of Fe, and 0.5 to 10% by weight of Co. Further, as the binding phase forming component, Cu: 0.5 to 10% by weight is further contained.

１５の移動不良が生じるという問題点もある。However, the weight 15 made of steel balls still has a problem that it is inconvenient to obtain a large amount of eccentricity because of its low specific gravity. Further, since the weight 15 is formed of mild steel, the inside of the hollow portion 14 is sealed, but rust is generated on the surface over time due to the enclosed moisture and oxygen. As a result, there is also a problem in that when used for a long period of time, poor movement of the weight 15 occurs.

なくなるという問題点がある。In particular, when the above-mentioned pseudo bait apparatus is reduced in size, the weight 15 is inevitably reduced, so that two weights 15 made of steel balls are used in a row. In any case where one weight 15 made of the W-Ni-Fe-based material is used, sufficient weight and eccentricity cannot be obtained, so that the air resistance in the main body 11 is larger than the weight of the weight 15 during casting. However, there is a problem that a sufficient flight distance cannot be obtained.

Sufficient weight and eccentricity can be obtained for the distance and tail swing operation, and even when two magnets are arranged in series with the artificial bait device magnet, enough magnets are magnetized. It is an object of the present invention to provide a weight for a pseudo bait apparatus having excellent magnetizing force and excellent corrosion resistance.

Specific gravity. Further, by adding Fe and Ni in the above-mentioned ranges by weight to the tungsten, a sufficient magnetizing force can be obtained by the cooperation of the two components. By the way,

e, according to the weight formed of sintered bonding gold of W-Ni-Fe-Co, W-Ni-Fe-Cu, or W-Ni-Fe-Co-Cu, a high specific gravity of 9.0 to 13.9 and , A sufficient magnetizing force of 90 to 95% of the steel ball can be obtained.

It is possible to obtain a sufficient weight and eccentricity for performing the flight distance and the tail swing operation. In addition, since the magnet has a sufficient magnetizing force, two magnets can be magnetized even if two magnets are arranged in series with the magnet of the artificial bait device. Furthermore, tungsten, which is the main component,
Since it is excellent in corrosion resistance and there is no possibility of rust progressing with time and causing poor rolling like steel balls, stable rolling performance can be maintained for a long period of time.

れるものの、比重が低下して不都合だからである。Here, in the invention according to any one of claims 1 to 3, the inclusion of Ni and Fe is an essential component because the required magnetizing force cannot be obtained only with tungsten. And Ni or Fe
This is because the above magnetizing force cannot be obtained even if only one of the above is added. The reason why the content of Ni is set in the range of 15 to 35% by weight and the content of Fe is set in the range of 15 to 35% by weight is that if each of the contents is less than 15% by weight, they are all sufficient. If the content of both components exceeds 30% by weight, a sufficient magnetizing force can be obtained, but the specific gravity decreases, which is inconvenient.

Here, the reason why the content of Co is set in the range of 0.5 to 10% by weight is that if the content is less than 0.5% by weight, the effect of increasing the magnetizing force cannot be obtained. If the amount is more than 10% by weight, the specific gravity is lowered and it is inappropriate.

The reason for limiting to the range is that, as in the case of Co, if the content is less than 0.5% by weight, the effect of increasing the magnetizing force cannot be obtained, while if the content exceeds 10% by weight, This is because the specific gravity is lowered and is unsuitable.
