Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish-type simulated bait, a so-called lure, which produces a variety of actions by moving the center of gravity.

[0002]

2. Description of the Related Art Lure fishing has become popular and many types of lures have been developed and used. These lures have been devised in various ways to attract fish. One of them is a lure that exercises as if a small fish were swimming, and minnow plugs, vibration plugs and the like are known as such lures. Although these lures repeat a continuous movement as if a small fish swim by reeling, the continuous movement is periodic, monotonous, and has little change.

[0003] Therefore, a lure designed to attract fish more effectively by adding irregular movements to such periodic swimming movements so as to bring them closer to the natural movements of small fish as baits. Is proposed. For example, Japanese Patent Laid-Open No. 9-
56295, JP-A-10-337134,
In Japanese Patent Laid-Open No. 2001-218540, a weight that can move in the vertical direction is provided inside the lure body, and the weight is moved upward by the rod action to have a high center of gravity, thereby balancing the lure. A lure that breaks down and makes an irregular movement is proposed.

In Japanese Utility Model Registration No. 3038618, a shaft which penetrates the tail portion from the inside of the lure body is provided, a weight having an eccentric center of gravity is fixed to the inside of the lure body, and the outside of the tail portion of the shaft is fixed. A lure has been proposed in which a rotary wing body is provided in a portion projecting to, and fine vibration can be given by rotation of a weight whose center of gravity is eccentric due to rotation of the rotary wing body.

[0005]

However, a vertically movable weight is provided inside the lure body, and this weight is moved upward in the lure body by a rod action to form a high center of gravity. In the former lure that made the irregular movement by breaking the balance of
There is a problem that the weight cannot be moved to a position of high center of gravity unless a rod action is given, and such rod action requires skill and cannot be easily performed by anyone.

Further, a shaft penetrating the tail portion from the inside of the lure body is provided, a weight having an eccentric center of gravity is fixed inside the lure body of the shaft, and a rotary wing body is provided at a portion protruding outward from the tail portion of the shaft. The latter lure, in which the fine vibration is given by the rotation of the weight whose eccentricity is caused by the rotation of the rotor body, has a problem that the structure is complicated, the manufacturing is troublesome, and the cost is high.

The object of the present invention is that anyone can easily add an irregular motion to a periodic swimming motion without the need for a skillful rod action or the like, and a motion which is rich in simplification. In addition, it is possible to provide a lure that has a simple structure, is easy to manufacture, and can be manufactured at low cost.

[0008]

In order to achieve the above object, a lure according to a first aspect of the present invention is rotatably supported in a space formed inside a luer body and at a position deviated from a rotation axis.

The front end of the tubular space 25 for forward and backward movement is communicated with the tubular space 22 for rotational movement, and the weight 24 housed in the tubular space 22 for rotational movement is the tubular space for forward and backward movement. It is possible to move within 25.

By doing so, when the lure is thrown with its rear end side forward, the weight 24 housed in the rotational movement tubular space 22 and magnetically attached to the ring 23 is provided.
Enters the tubular space 25 for forward / backward movement due to inertia and moves to the rear end side of the tubular space 25 for forward / backward movement, that is, the rear end side of the lure body 1 to extend the throwing distance, and the weight 24 causes the weight 24 to move to the front end. To enter the rotational movement tubular space 22,
When the lure body 1 is magnetically attached to and retained on the ring 23 and starts reeling, the lure body 1 cyclically repeats a scheduled swimming motion according to its shape, and the lure body 1 performs the cyclical repeating swimming motion. The weight 24 housed in the cylindrical space 22 for rotation movement formed inside the main body 1 and magnetically attached to the ring 23 rolls on the inner peripheral surface of the ring 23 while being magnetically attached to the ring 23. The lure body 24 is rotated, and the center of gravity of the lure body 1 is moved in the same direction by the movement of the weight 24. The centrifugal force due to the movement of the center of gravity acts on the periodic swimming motion of the lure body 1 to cause a periodical movement. Causes an irregular movement that is different from exercise.
