Abstract

PROBLEM TO BE SOLVED: To provide a lure for fishing, targeting a buzz bait, and having a buzz blade capable of rotating always in a good state. SOLUTION: A nearly U-shaped shaft 2 comprising a front arm part 21, an upper arm part 22, an engaging part 23 for a fishline T, and a lower arm part 24 is formed out of a wire made of a shape memory alloy. A wire portion at the prescribed back end side of the upper arm part 22 is subjected to a forging treatment to make the portion a region of no shape memory. A bead member 7, the buzz blade 3, a bead member 8 and a sheath pipe member 9 are outserted on the upper arm part 22, and the wire portion is bent not only to form a bent end part 25 but also to form a contacting protrusion 251 for causing a contacting sound by bringing the protrusion 251 into contact with tilted wing parts 31 and 31 of the buzz blade 3. A hook is fixed to the lower arm part by pressing and forming a sinker body 4 having a prescribed shape while engaging the base engaging part 51 of the hook 5 with the bent engaging part 24 at the lower arm part. The buzz blade is kept always in a good rotation state because even if bending deformation is caused in the shaft, the shaft is automatically recovered to the original shape.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing lure used for lure fishing, and more particularly to a fishing lure suitably applied to a lure of a type called buzzbait.

[0002]

2. Description of the Related Art Conventionally, a rubber jig composed of a weight, a hook, and a rubber skirt is connected to one end of a shaft formed by bending a wire into a "-" shape, and a spinner is swingable at the other end. 2. Description of the Related Art Fishing lures belonging to a combination lure type called a spinner bait mounted on a fishing lure are generally known. It is also known that the above-mentioned U-shaped shaft of the spinner bait is formed of a shape memory alloy (for example, see Japanese Patent No. 3037879).

[0003] A fishing lure called buzzbait is also known as a kind of the combination lure type. This buzzbait is formed by bending a wire into a “U” shape (simply referred to as a “U” shape) consisting of a forearm portion, an upper arm portion, and a lower arm portion. And a propeller-shaped rotating blade is mounted on the upper arm of the shaft so as to be rotatable around its axis. While the spinner of the spinner bait swings and swings in the water, the rotating blades of the buzz bait rotate due to the resistance of the water as the buzz bait is pulled through the fishing line, and the buzz bait rotates due to contact with water particularly near the water surface. A bouncing sound is generated.

[0004]

However, in the above-mentioned conventional buzzbait, since the rotation of the rotating blade is not a swing motion like a spinner but a uniaxial rotation with the upper arm as a rotation axis, the buzzbait is a fishing line. Depending on the direction of the upper arm when pulled, the rotating blades may not be able to rotate smoothly or may not be able to rotate.

That is, if the initial state is maintained, the fishing line is tied to the locking portion formed at the intersection of the forearm and the lower arm, and when the buzzbait is pulled through the fishing line, the lower arm The part is placed in the lower position by the weight, the upper arm part is in the upper position, and the forearm part is arranged to extend in the up-down direction. However, when the fish is eaten on the hook, the weight of the fish acts, so that the lower arm of the hook is bent downward from the base of the forearm and the lower arm of the shaft or from the middle of the lower arm. Further, when the hook is attached to a water plant or the like, an excessive force is applied to the locking portion in order to peel it off, so that the lower arm may be bent. Further, the upper arm may be bent from the base of the forearm and the upper arm by the rotating blades catching or colliding with algae or suspended matter on the water surface. In such a case, it is used after the user manually restores the upper arm and the lower arm to the initial state, but it may be difficult to restore the original shape. For this reason, if the opening angle of the lower arm or the upper arm with respect to the forearm is out of alignment, the balance of the overall posture by the weight is out of order, so that when the buzzbait is pulled by the fishing line, the upper arm is considerably inclined with respect to the traveling direction of the buzzbait. Even if the arrangement is provided with the resistance of water, the rotating blades will cause poor rotation.

[0006] The present invention has been made in view of such circumstances, and an object of the present invention is to make it possible to always rotate the rotating blades provided on the buzzbait in a good condition especially for the buzzbait. An object of the present invention is to provide a fishing lure. It is another object of the present invention to provide a method for manufacturing such a fishing lure.

[0007]

According to a first aspect of the present invention, there is provided a fishing lure having a substantially U-shaped shaft. The shaft includes a forearm and a forearm. A wire bent substantially in a U-shape so as to have an upper arm extending rearward from the upper end of the portion and a lower arm extending rearward from the fishing line engaging portion provided at the lower end of the forearm. And the wire is formed of a shape memory alloy. A weight and a hook-type hook are provided on the free end side of the lower arm, and a propeller-shaped rotary blade is loosely fitted to the upper arm so that the propeller-shaped rotating blade can rotate substantially at a fixed position using the upper arm as a rotation axis. (Claim 1).

According to the first aspect of the invention, after the lure has been cast and the engaging portion is pulled through the fishing line, the lower arm of the substantially U-shaped shaft is lowered by the weight.
The rotating blade of the upper arm moves forward in an upright position, and the forward movement causes the rotating blade to rotate due to the resistance of water. Then, when the fish attracted to the water splashing sound generated due to the rotation of the rotating blades clings to the hook provided on the lower arm, an impact force acts, and when the fish is pulled up, the weight of the fish is reduced. As a result, a bending force acts on the side where the lower arm is opened with respect to the forearm. Alternatively, the hook may be attached to an aquatic plant or obstacle such as underwater and may be pulled by applying an excessive tensile force in order to remove it, and a bending force similar to the above may act on the shaft. Even if the lower arm is bent by such a bending force, since the entire shaft is formed of a shape memory alloy, when the bending force is removed, the shaft returns to the original shape before the fish bites. become. Therefore, even when casting is performed again, it is possible to reliably move forward in the same posture as before the fish bite, rotate the rotating blades, and draw the fish.

In the first aspect of the present invention, the following bent end may be added.

In other words, a wire portion on the free end side of the upper arm portion where the rotary blade is loosely fitted is defined as a non-shape memory area,
The wire portion may be bent to form a bent end portion so as to prevent the rotating blade from falling backward when the rotating blade is loosely fitted (claim 2). This allows
Even with a shaft made of a shape memory alloy, the bent end portion can be reliably and easily formed as a stopper for the rotating blade.

Further, as another bent end, a wire portion on the free end side of the upper arm portion where the rotary blade is loosely fitted is set as a non-shape memory area, and the wire rod is loosely fitted with the rotary material. The part is bent toward the lower arm side to form a bent end, and the bent end comes into contact with a part of the rotating blade with the rotation of the rotating blade to generate a contact sound. A contact projection may be provided (claim 3). In this case, it is possible to generate not only the water splashing sound but also the contact sound with the contact convex portion in addition to the water splashing sound by the rotation of the rotary blade. This makes it possible to further increase the action of attracting fish.

The "contact convex portion" may be formed integrally with the bent end portion by bending a free end of the wire portion (claim 4). In this case,
It is possible to easily form the contact projections that generate the contact noise as described above without increasing the number of components. Then, when the rotating blade comes into contact with the contact convex portion integrated with the bent end portion while rotating, fine vibration occurs in the entire upper arm portion or the shaft through the bent end portion, and the fish Can be further increased.

Alternatively, the above-mentioned “contact convex portion”
The enlarged member may be configured to have a larger diameter than the wire portion, and the enlarged member may be loosely fitted to the wire portion so as to be rotatable around the wire portion by contact with a rotating blade. (Claim 5). In this case, a part of the rotary blade contacts the expanding member while rotating, and the contact causes the expanding member to rotate following the axis of the bent end and generate a contact sound. Therefore, in the case of claim 4 described above, the generated contact sound is a relatively hard contact sound because it is formed integrally with the bent end portion. Since the rotation is driven by the contact, a relatively soft sound can be generated. Therefore, it is possible to use differently according to the fish to be caught.

Further, as a mode in which the weight and the hook are provided to the lower arm portion in the first invention, a bent locking portion in a bent state is previously provided at a free end of a wire constituting the lower arm portion. On the other hand, the base end locking portion of the hook is locked to the bent locking portion, and the weight body straddles the base end portion of the hook and the bent locking portion of the lower arm. It may be provided in a state in which both are closely contacted and covered (claim 6). By doing so, even when the shaft is formed of a shape memory alloy, the weight and the hook can be easily and reliably attached to the lower arm.

According to a second aspect of the present invention, there is provided a method of manufacturing a fishing lure according to any one of claims 2 to 5, wherein the forearm extends vertically, and extends straight rearward from the upper end of the forearm. A shape memory alloy is used to form a shaft intermediate body that is bent in a substantially U-shape so as to have an upper arm portion and a lower arm portion that extends rearward from a fishing line engaging portion provided on the lower end side of the forearm portion. An intermediate body forming step of integrally forming the wire body, and annealing the wire part on the free end side from the part where the rotating blades of the shaft intermediate body are loosely fitted, thereby making the wire part a non-shape memory area. A shape memory processing step, and between the intermediate forming step and the non-shape memory processing step, or after the non-shape memory processing step, an upper arm portion of the shaft intermediate body Propeller-like rotation It is a specific matter that a part assembling step of loosely fitting the root is performed, and thereafter, a bending step of forming a bent end portion by bending the wire material portion that is the non-shape memory area is performed. (Claim 7).

According to the second aspect of the present invention, first, in the intermediate body forming step, the shaft intermediate body whose shape memory has been applied in a state where the upper arm is extended in a straight line is formed, and in the non-shape memory processing step, the shaft intermediate body is formed. A predetermined wire portion on the free end side of the portion is set as a non-shape memory area, and is in a state where plastic deformation is possible. After this non-shape memory processing step, or between the above-mentioned intermediate body forming step and the non-shape memory processing step, a component assembling step is performed, and the rotating blade is mounted to the above-described linearly extended upper arm portion. Can be Then, the wire portion, which is the non-shape memory area, is bent to form a bent end. As described above, even when the shaft is formed of a shape memory alloy, the bent end portions according to claims 2 to 5 can be formed easily and reliably. In the case of the fishing lure according to the fourth aspect, a step of forming a contact convex portion by further bending a part (for example, a free end) of the bent end may be added. In the case of a fishing lure, a step of loosely fitting an enormous member to the bent end may be added.

[0017]

As described above, according to the fishing lure of any one of claims 1 to 6, even if the lower arm or the like is bent and deformed by the application of a bending force, the shape memory function is used. When the bending force is removed, the shaft can be reliably returned to the original substantially U-shape. For this reason, even if it is repeatedly used, it is possible to ensure that the rotating blades are kept in the expected rotatable state and that the rotating blades can always be rotated in a favorable state, and to exert the effect of attracting fish. .

In particular, according to the second aspect, even if the shaft is formed of a shape memory alloy, the bent end portion can be reliably and easily formed as a stopper for the rotating blade.

According to the third aspect, by the rotation of the rotary blade, in addition to the water splashing sound, it is possible to generate the contact sound with the contact convex portion provided at the bent end portion of the second aspect. The effect of attracting fish can be further increased.

According to the fourth aspect, the contact convex portion according to the third aspect can be formed integrally with the bent end portion, and the contact convex portion that generates the contact sound as described above can be formed without increasing the number of components. It can be easily formed. In addition, the rotating wings contact the contact projections while rotating, so that micro-vibration can also be generated in the upper arm or the entire shaft through the bent ends, and the action of attracting fish is achieved. It can be further increased.

According to the fifth aspect, the contact convex portion of the third aspect is constituted by an enlarged member loosely fitted to the bent end portion,
The contact projection can be provided without any processing on the bent end itself. In addition, since a part of the rotating blades comes into contact with the expanding member while rotating, the contact sound can be generated while the expanding member is driven to rotate. A soft contact sound can be generated and can be used properly depending on the fish to be caught.

According to the sixth aspect, even when the shaft is made of a shape memory alloy, the weight and the hook can be easily and reliably attached to the lower arm.

According to the method of manufacturing a fishing lure according to claim 7, even when the shaft is formed of a shape memory alloy, the bent end of any one of claims 2 to 5 can be easily formed. In addition, it is possible to surely form the fishing lure, whereby the effect of the fishing lure according to any one of claims 2 to 5 can be reliably obtained.

[0024]

Embodiments of the present invention will be described below with reference to the drawings.

<First Embodiment> FIG. 1 shows a buzzbait 1 as a fishing lure according to a first embodiment of the present invention, 2 is a shaft, 3 is a buzz blade as a propeller-shaped rotating blade, and 4 is a buzzbait. The weight 5 is a hook of hook type, and 6 is a rubber skirt colored appropriately.

The shaft 2 has a predetermined diameter (for example, 1 mm).
(Diameter) of a wire made of a shape memory alloy such as an ultrahigh elastic wire, an upper arm 22 extending rearward (to the right in FIG. 1) from an upper end of the forearm 21, and a lower end of the forearm 21. It is formed in a state of being bent in a substantially U-shape so as to have a lower arm portion 24 extending rearward from the fishing line locking portion 23 formed at the position. The free end side of the upper arm 22 is a bent end 2 which is a non-shape memory area as described later.
5 are integrally formed.

The overall shape of the shaft 2 will be described in more detail with reference to the lower arm 24. The forearm 21 is positioned on the rear side so that the intersection angle (inner angle) with the lower arm 24 is smaller than 90 degrees. The upper arm 22 extends upward in a state of being inclined toward the rear, and the upper arm 22 opens rearward from a direction parallel to the lower arm 24, that is, the lower arm 24
Extending gradually away from the At the intersection of the forearm portion 21 and the lower arm portion 24, a locking portion 23 for locking the fishing line T is formed so as to be folded round, and the upper arm portion is provided at the free end side of the lower arm portion 24. A lower arm end 241 bent so as to extend substantially parallel to the portion 22 and a free end of the lower arm end 241 are bent to form a bent engagement portion 242. Further, the upper arm 22 is bent at a predetermined angle from a predetermined position on the free end side to the lower arm 24 side to form the bent end 25. The free end of the bent end 25 is bent round. Thus, the contact convex portion 251 is formed integrally. The bending angle of the bent end portion 25 and the size of the contact convex portion 251 are determined so that when the later-described inclined wing portions 31 of the buzz blade 3 rotate, the surfaces of the inclined wing portions 31 slightly contact each other. It is set to be able to.

The buzz blade 3 is formed integrally by, for example, bending a metal plate of stainless steel plate or molding with a synthetic resin. More specifically, the buzz blade 3 includes a pair of wings 32 and 32 each having an inclined wing 31 at a rear end position, and a front end pivot portion bent at a front end position in a direction perpendicular to the plane of FIG. 33, and a rear end pivot portion 34 that is bent at the rear end position toward the near side in the orthogonal direction.
And a semi-circular groove 35 bent so that the front half portion connecting the front and rear ends of the two shaft supporting portions 33 and 34 opens to the back in the orthogonal direction, and the rear half portion opens to the near side in the orthogonal direction. And a bent semicircular groove 36.

A through hole having an inner diameter larger than the outer diameter of the upper arm portion 22 is formed in each of the front and rear ends of the shaft support portions 33 and 34, and the inner surfaces of the two semicircular grooves 35 and 36 are also formed outside the upper arm portion 22. It is formed to have an inner diameter larger than the diameter. Then, the front end shaft support portion 33 and the two semicircular grooves 35 and 36 are provided.
And the upper arm portion 22 is loosely inserted into the rear end pivot portion 34 so that the buzz blade 3 is rotatable about the upper arm portion 22 as a rotation axis and is slightly movable back and forth with respect to the upper arm portion 22. It is pivoted on.

Further, the inclined wing portions 31, 31 receive the water resistance from the front to the rear generated by the buzz bait 1 being pulled forward (to the left in FIG. 1) via the fishing line T, thereby causing the buzz blade 3 to move. It is tilted so as to rotate and change the received water into a vortex centered on the upper arm 22 which is the rotation axis. The rotation of the buzz blade 3 maintains the posture of the upper arm 22 as described later.

A component for smoothly rotating the buzz blade 3 at a substantially fixed position is inserted into the upper arm 22 of the buzz blade 3 at the front and rear positions. That is, for example, a steel ball (bead) member 7 made of stainless steel or the like is provided at a front position of the buzz blade 3, a similar bead member 8 is provided at a rear position of the buzz blade 3, and a sheath tube member 9 as a tubular spacer. Are movably inserted into rear positions of the bead members 8, respectively. The bead member 7 is configured such that the front end pivot 33 of the buzz blade 3 is the upper arm 22.
The bead member 8 and the sheath tube member 9 are disposed so as not to bite into the bent portion 261 of the forearm portion 21 and the forearm portion 21.
Serves as a stopper for the backward movement of the buzz blade 3 so as to maintain a predetermined contact with the contact convex portion 251 when receiving the resistance of water, and serves as a stopper for the bead member 8.
The smooth contact of the buzz blade 3 is realized by the line contact between the buzz blade 3 and the rear end pivot portion 34.

The weight 4 has an annular proximal locking portion 51 formed on the proximal side of the hook 5 and a bent locking portion 242 of the lower arm portion 24.
Are formed around the lower arm end 241 and the base end locking portion 51 in a state of being locked and connected to the outer periphery. The weight 4 is made of, for example, a lead material by the lower arm end 241.
After being wound around the outer periphery of the base locking portion 51, it is formed by being put into a predetermined press mold and subjected to press working, whereby the lower arm end 241 and the base locking portion 51 are brought into close contact with each other. Thus, both are fixed so as not to move relative to each other. Note that the weight 4 may be formed by casting using molten lead. In this case, molten lead may be poured in a state where the connected lower arm end 241 and the base end locking portion 51 are inserted into a predetermined casting mold and cooled and hardened. Further, as a forming material, a metal having a high specific gravity may be used in addition to the lead material.

The buzzbait 1 having the above-described structure is provided with
The fishing line T is locked and cast in a connected state, and by pulling the fishing line T, the underarm 24 is in the lower position by the weight 4 and the upper arm 22 is in the upper position in the water by pulling the underwater, In addition, the upper arm portion 22 moves forward (to the left in FIG. 1) in a posture in which the upper arm portion 22 has a slight downward slope (see FIG. 1). With this advance, the buzz blade 3 is positioned so as to contact the bead member 8 by receiving the resistance of the water, and is rotated at this fixed position. With the rotation of the buzz blade 3, a lift is applied to the upper arm 22 to lift the upper arm 22 upward, so that the buzz bait 1 is raised in the water and near the water surface W. On the other hand, since a downward force is acting on the lower arm 24 by the weight body 4, the entire buzzbait 1 is always moved forward in the same posture as shown in FIG. At the same time, the rotation of the buzz blade 3 causes a water splashing sound near the water surface W, and the inclined wings 31, 31 rotate while slightly touching the contact convex portion 251, thereby generating the contact sound, thereby generating fish. Will be attracted.

Then, the fish is eaten by the hook portion 52 turned upward, and the buzzbait 1 is hooked through the fishing line T and the fish is pulled up. Even if bending deformation occurs due to the action, when the external force is removed, the shaft 2 automatically restores its original shape. For this reason,
Even if the buzzbait 1 is pulled again by casting again, the buzzbait 1 is surely moved forward while maintaining the same posture as described above, whereby the buzz blade 3 can be always rotated in a favorable state.

In order to manufacture the buzzbait 1 described above, FIG.
As shown in (1), first, the shaft intermediate body 2a whose shape is memorized is formed in a state where the upper arm portion 22 is extended in a straight line (intermediate body forming step). The shaft intermediate body 2a includes an upper arm portion 22 extending linearly, a forearm portion 21 having a locking portion 23, a lower arm end portion 241 and a bent locking portion 24 on a free end side.
2 and a lower arm 24 having a lower arm 2. That is,
The shaft intermediate body 2a includes a bent portion 261 and a locking portion 2
3 and a bent portion 263 from the lower arm 24 to the lower arm end 241
And the bent end portions 242 are bent or bent so that the internal stress is removed and the internal shape is deformed when an external bending force is applied, but is automatically restored to the original shape when the external bending force is removed. It is formed to have shape memory or super high elasticity.

Next, the bead member 7, the buzz blade 3, the bead member 8, and the sheath tube member 9 are inserted into the upper arm 22 in this order (part assembling step). Thereafter, a process of setting the wire portion 221 on the free end side (rear end side) from the predetermined position of the upper arm portion 22 to a non-shape memory area, that is, an area where shape memory is released and plastic deformation is possible is performed (non-shape memory area). Shape memory processing step). As this process, an annealing process in which the wire portion 221 is heated at a predetermined temperature (for example, 800 ° C. or lower) and then gradually cooled (natural cooling) may be performed. At this time, a cooling process may be added to the upper arm portion 22 other than the wire rod portion 221 as needed.

Thereafter, the wire portion 221 is bent downward to form the bent end portion 25, and the free end is bent to form the contact convex portion 251 (bending step).

On the other hand, in parallel with the above-mentioned component assembling step or next to the above-mentioned step of forming the bent end portion 25, the base end locking portion 51 of the hook 5 to which the rubber skirt 6 is integrally attached in advance is connected to the hook portion 52. May be locked (fitted) into the bent locking portion 242 in a state in which the weight is directed upward, and the weight 4 may be formed in this locked state. The weight 4 may be formed by a method such as press molding or casting as described above.

A ball member 10 whose outer diameter is set so that the inclined wing portions 31 can come into contact with the rotation of the buzz blade 3 is movably inserted into the bent end portion 25a. The ball member 10 may be formed of a synthetic resin or a metal if a contact sound is generated, but preferably a stainless steel ball is used, and the steel ball is slightly larger than the bent end portion 25a. It may be formed by opening a through hole having an inner diameter. The free end of the bent end 25a is bent at a right angle to form a retaining portion 252 of the ball member 10.

The buzz bait 1a of the second embodiment as described above
As shown in FIG. 4, first, the upper arm 22 is manufactured.
Is different from that of the first embodiment only in that the length of the shaft intermediate body 2a differs from that of the first embodiment only in that the length of the bent end 25a differs from that of the bent end 25 of the first embodiment. (Intermediate forming step).

Next, the bead member 7, the buzz blade 3, the bead member 8, the sheath tube member 9 and the ball member 10 are inserted into the upper arm 22 in this order (component assembling step).
Thereafter, the process of setting the wire portion 221 on the free end side (rear end side) from the predetermined position of the upper arm portion 22 to a non-shape storage area is performed in the same manner as in the first embodiment (non-shape storage processing step).

After that, with the ball member 10 positioned at the wire portion 221, the wire portion 221 is bent downward to form the bent end 25 a, while the free end is bent. It is bent to form the retaining portion 252 (bending step).

On the other hand, in parallel with the above-mentioned component assembling step or next to the above-mentioned step of forming the bent end portion 25, the base end locking portion 51 of the hook 5 to which the rubber skirt 6 has been previously attached integrally is connected to the hook portion 52. May be locked (fitted) into the bent locking portion 242 in a state in which the body is turned upward, and the weight 4 may be formed in the same state as in the first embodiment.

In the case of the buzzbait 1a of the second embodiment described above, the buzzbait 1a is rotated underwater by the rotation of the buzz blade 3 similarly to the buzzbait 1 of the first embodiment.
In water and near the water surface W in the same posture as shown in FIG. At the same time, the rotation of the buzz blade 3 generates a water splashing sound near the water surface W, and the inclined wings 31, 31 rotate while slightly contacting the ball member 10 to generate a contact sound, thereby attracting the fish. Will be. At this time, the ball member 10 rotates about the bent end 25a as a rotation axis due to the contact with the inclined wing portions 31, 31 or is flipped upward along the bent end 25a. In addition, the contact sound is softer than in the case of the first embodiment, and the contact sound may or may not sound, so that the fish can be further attracted.

Then, similarly to the first embodiment, the shaft 2
Even if a bending external force acts on the side where the lower arm 24 is opened downward, bending deformation occurs, and when the bending external force is removed, the shaft 2 automatically restores its original shape. For this reason, even if the buzzbait 1a is cast again and pulled, the buzzbait 1a is reliably moved forward while maintaining the same attitude as described above, whereby the buzz blade 3 can be always rotated in a favorable state. Become like

<Other Embodiments> The present invention relates to the first embodiment.
The present invention is not limited to the second embodiment, and includes various other embodiments. That is, in the buzz baits 1 and 1a of the first and second embodiments, the contact protrusion 25 that generates the contact sound by the rotation of the buzz blade 3 is provided.
The buzz blade 3 is provided with the bent ends 25 and 25a provided with the ball member 10, but is not limited thereto. It may be one that exhibits a stopping function. In this case, the bent end portion 25b may be formed by performing a process of setting a very small length portion on the free end side of the upper arm portion 22 to a non-shape memory region as a wire portion and then bending the wire portion.

In the first and second embodiments,
A non-shape memory processing step of setting the wire rod portion 221 to a non-shape storage area is performed after the component assembling step. However, the present invention is not limited to this. The non-shape memory processing is performed first, and then the component assembling step is performed.

Further, in the first and second embodiments,
Both of them are subjected to the process of making them into non-shape memory areas,
25a is formed, but the invention is not limited to this, and processing for making such a non-shape storage area and the bent ends 25, 25a are performed.
May be omitted. In this case, a component for preventing the buzz blade 3 from falling backward may be attached to the free end of the upper arm portion 22, or a projection for preventing the buzz blade 3 may be welded by brazing or the like. For example, as in a buzzbait 1c shown in FIG. 6, the sheath tube member 9 may be flatly pressed and deformed by pliers or a press machine and fixed to the upper arm portion 22 by pressure bonding. In the case of such a form, the contact sound is not generated by the rotation of the buzz blade 3, but the fish can be attracted by the generation of the water splashing sound. In addition, since the entire shaft is formed of the shape memory alloy, the bending is performed. Even if deformation or the like occurs, the original shape can be automatically restored to the original shape, and the rotation operation of the buzz blade 3 can be always maintained in a good state.
