Description

The present invention relates to artificial baits used, for example, when fishing for squid.

2. Description of the Related Art Conventionally, various artificial baits have been used in fishing.
Fishing using artificial bait is also called lure fishing, and usually involves casting the artificial bait into the target spot using a rod. In this type of lure fishing, an artificial bait that can be cast farther and more stably is required.
For example, Patent Document 1 discloses an artificial bait that has a horizontally long main body, a line eye attached to one side of the main body in the longitudinal direction, a needle attached to the other side of the main body in the longitudinal direction, a weight for moving the center of gravity, and a weight storage space inside for movably storing the weight, a part of which protrudes outward from the bottom of the main body on the line eye side, and the remaining part of which is a weight storage part that extends inside the main body in the longitudinal direction toward the needle side, the weight storage space extending from a protruding part protruding outward from the main body to the needle side, and is formed so that when the weight is moved into the protruding part, the center of gravity of the weight is located outside the main body, in order to increase the flight distance during the casting stage. In this artificial bait, the weight can move back and forth, that is, the center of gravity of the artificial bait can move back and forth, which increases the flight distance.

Patent No. 5616575

However, while an artificial bait with a moving center of gravity, such as that described in Patent Document 1, can be expected to fly long distances, the flight distance varies with each throw, and it may not be possible to cast it stably over a long distance.

The objective of the present invention is to provide an artificial bait that has a relatively long flight distance and is less likely to vary in flight distance each time it is cast.

The inventors first analyzed in detail the flying posture of the artificial bait when it was cast. When the artificial bait was cast, it received a moderate amount of resistance due to the line being pulled by the reel, and also received air resistance at the tip side in the flying direction. During this flight, the artificial bait rotates, and as a result of the increased air resistance, the cast artificial bait stalls. It is considered that the flying distance of the artificial bait is not the same every time it is cast, depending on the degree of rotation of the artificial bait. In other words, when the artificial bait is cast multiple times in the same way, it may be cast relatively far in some cases, but may be cast shorter in other cases. Therefore, the inventors tried to attach a structural member such as an airplane tail to the rear part of the artificial bait in order to increase the rectification effect, or to attach a plate-shaped resistance plate to the artificial bait in order to intentionally increase the air resistance, or conversely, to remove the structural part protruding from the artificial bait in order to reduce the air resistance, but they could not ensure a stable flying distance every time it was cast.
As a result of such trial and error, the inventors have completed an artificial bait that can stably ensure a long flight distance.

The artificial bait according to the first aspect of the present invention comprises an artificial main body and a flexible string-like body attached to the artificial main body, the artificial main body having a body, a line connection part provided in the front part of the body, and a weight provided on the body, the first end of the string-like body on one side in the longitudinal direction is attached to a mid-way part in the longitudinal direction of the artificial main body, with the first end of the string-like body facing the rear side of the artificial main body and the second end of the string-like body on the opposite side in the longitudinal direction facing the front side of the artificial main body, and the second end of the string-like body being a free end.

The artificial bait of the second aspect of the present invention is the artificial bait of the first aspect, wherein the weight protrudes downward from the body at a midpoint in the fore-and-aft direction of the body, and a first end of the string-like body is attached to the weight.
The artificial lure according to a third aspect of the present invention is the artificial lure according to the second aspect, wherein a first end of the string-like body is attached to a rear portion of the weight.
The artificial bait of a fourth aspect of the present invention is the artificial bait of the third aspect, wherein an attachment part is provided at the rear part of the weight, a first end of the string-like body is attached to the attachment part, and at least the part of the rear part of the weight where the attachment part is provided is chamfered.

The artificial bait according to the fourth aspect of the present invention is the artificial bait according to the first aspect, in which the weight is embedded in the body.

The artificial bait according to the fifth aspect of the present invention is the artificial bait according to any one of the first to fourth aspects, in which the string-like body is composed of a collection of multiple string-like bodies pulled together.

The artificial bait of the present invention can be cast a relatively long distance, and the flight distance is less likely to vary each time it is cast.

Hereinafter, the artificial bait of the present invention will be described with reference to the drawings.
In this specification, "forward" refers to the side in which the artificial bait moves when a line tied to the artificial bait is pulled in water, "rearward" refers to the opposite side to the forward, and the direction connecting the forward and rear is called the "front-rear direction." In addition, in this specification, "upper" refers to the side perpendicular to the front-rear direction and closer to the water surface based on the artificial bait when in use (when the artificial bait is swimming in water), and "lower" refers to the opposite side to the upper, i.e., the side closer to the bottom of the water based on the artificial bait when in use in water, and the direction connecting the upper and lower is called the "vertical direction." In addition, in this specification, "width direction" refers to the direction perpendicular to the vertical direction and the front-rear direction.

In Figs. 4 and 5, the rubber tube is shown in cross section.
1 to 5, an artificial bait 1 of the present invention comprises a decorated artificial body 2 and a flexible string-like body 3 attached to the artificial body 2. The flexible string-like body 3 is a flight stabilizing member for enabling the artificial bait 1 to be cast stably for a long distance.

<Pseudo body>
The pseudo main body 2 has a body 4, a line connecting portion 5 provided at the front portion of the body 4, a weight 6 provided on the body 4, and a fishing hook 7 provided on the body 4. The pseudo main body 2 may have other components in addition to decorative materials such as cosmetic materials.

The body 4 is the main part of the artificial bait 1 and constitutes most of the external shape of the artificial bait 1. The shape of the body 4 is appropriately set according to the type of target fish (fish and fish-like objects that are the subject of fishing. Target fish is a general term for underwater objects that are the subject of fishing, including squid and octopus). For example, the shape of the body 4 may resemble a crustacean or a small fish. The body 4 in the illustrated example is intended for use as a target fish, for example, a squid, and is formed in a shape that imitates the external shape of a shrimp. Since squids like shrimp, an artificial bait 1 that imitates the external shape of a shrimp is suitable for squid fishing. In other words, the artificial bait 1 in the illustrated example of the present invention is an artificial bait for squid fishing (a so-called egi).

The material for forming the body 4 is not particularly limited, and any material having a mechanical strength sufficient to withstand a bite by a target fish on the body 4 is used. Examples of such materials include resin, wood, and metal, and resin is preferably used. In particular, ABS resin is preferably used because it is easy to mold.
The body 4 may be formed to be hollow or solid. The body 4 of the artificial bait 1 in the illustrated example is formed to be hollow. The body 4 may be made up of one part, or may be made up of multiple parts. The body 4 of the artificial bait 1 in the illustrated example is formed by bonding two parts (halves) together with an adhesive or the like.
The body 4 is decorated. The decoration is applied to the body 4 by adding a decorative material to the body 4. The decoration mainly refers to an external component that is expected to stimulate the visual angle of the target fish and encourage predation. For example, a decorative material (not shown) is provided on the outer surface of the body 4. The decorative material may be a fabric with a desired color pattern, a film with a desired color pattern, or the like. The decorative material is fixedly attached to the outer surface of the body 4 via an adhesive or the like. In this specification, "fixedly attached" means that the decorative material is attached to such an extent that it cannot be easily removed by human power. In addition, if the body 4 has translucency so that the inside of the body 4 on which the decorative material is provided can be seen, a decoration such as a reflector (not shown) may be provided inside the body 4. In addition, if necessary, wings (not shown) may be provided on the outer surface of the body 4. However, since the string-like body 3 may be entangled in the wings, it is preferable to use a pseudo body 2 without wings, as shown in Figures 1 to 3.

The line connection part 5 is provided, for example, in the front part of the body 4. The line connection part 5 is a part to which the line (fishing line) is tied during use. The line connection part 5 is, for example, a metal ring part. The line connection part 5 can be formed, for example, using a U-shaped ring formed by bending a metal wire into a substantially U-shape. The end of the U-shaped ring is fixedly attached to the body 4, so that the line connection part 5 is provided in the front part of the body 4. The line connection part 5 is fixedly attached to the body 4, for example, by forming a locking part (not shown) such as a return prevention protrusion at the end of the U-shaped ring and locking the end of the U-shaped ring to a locking part (not shown) inside the body 4. The line connection part 5 is also provided so as to protrude forward from the front edge 42 of the body 4.

The fishhook 7 is, for example, provided at the rear of the body 4. In the illustrated example, an umbrella-shaped fishhook 7 is fixedly attached to the rear of the body 4. The fishhook 7 is fixedly attached to the body 4, for example, by fitting an end of the fishhook 7 into an insertion hole (not shown) provided at the rear of the body 4 and gluing the end to the insertion hole using an adhesive or the like. In place of such a fixed fishhook 7, a fishhook connecting part may be provided at an appropriate location on the body 4, and a hook-shaped fishhook (for example, a treble hook, etc.) may be attached to this fishhook connecting part (not shown). In addition, the position at which the fishhook 7 is provided is not limited to the rear of the body 4, and the position can be changed appropriately depending on the target fish, but it is preferable that the fishhook 7 is provided at a position that does not come into contact with the flexible string-like body 3. For example, as described later, when the string-like body 3 is attached to the weight 6, it is preferable that the fishhook is not provided around the weight 6 in order to prevent the string-like body 3 from getting tangled in the fishhook. In other words, it is preferable that the fishing hook is not attached directly or indirectly via a swivel or the like to the weight 6, but is instead attached to an appropriate location on the body 4 other than near the weight 6.

The weight 6 is for adjusting the weight of the artificial bait 1. Also, the center of gravity of the artificial bait 1 can be adjusted by changing the attachment position of the weight 6.
The weight 6 can be provided at an appropriate position, for example, at the rear part of the body 4, the front part of the body 4, or the midway part in the front-rear direction of the body 4. The midway part in the front-rear direction does not mean the midpoint of the front-rear direction length 4L of the body 4 (the length from the front edge 42 to the rear edge 43 of the body 4) (the midpoint is a half position when the front-rear direction length 4L of the body 4 is 1), but means any part in the front-rear direction length 4L. Since it is preferable that the center of gravity is closer to the front, in the illustrated example, the weight 6 is provided, for example, at a part closer to the front than the midpoint of the front-rear direction length 4L of the body 4. In terms of the positional relationship in the up-down direction, the weight 6 is provided at the lower part of the body 4 (the so-called abdomen in the shrimp-like body 4 as in the illustrated example).

The weight 6 may be embedded in the body 4 (not shown), or may be provided so as to protrude from the body 4 as shown. The weight 6 being embedded in the body 4 means that the weight 6 is provided so that a part or the whole of the weight 6 does not protrude from the surface of the body 4. Examples of the weight 6 being embedded in the body 4 include a case where the weight 6 is entirely covered by the material forming the body 4, a case where a part of the weight 6 is on the same plane as the surface of the body 4 but the weight 6 does not protrude from the surface of the body 4, and a case where the weight is accommodated in a weight accommodation space within the body as described below.
In the illustrated example, the weight 6 is provided in a portion midway in the fore-and-aft direction of the body 4, closer to the front than the midpoint, and protrudes from the midway portion downward from the body 4. The weight 6 is fixedly attached to the body 4 via an adhesive or the like.
The shape of the weight 6 is not particularly limited, but it is preferably plate-shaped in order to reduce air resistance and resistance in water. The plate-shaped weight 6 is attached to the body 4 in such a manner that its plate surface is included in the vertical and width directions of the body 4. Therefore, the weight 6 is attached to the body 4 with the upper side of the plate-shaped weight 6 aligned along the front-rear direction of the body 4. Examples of materials for forming the weight 6 include metals such as lead, copper, brass, tungsten, and iron.

<String-like body>
The string-like body 3 is provided on the pseudo body 2 .
The string-like body 3 is made of a flexible elongated member. The string-like body 3 may be made of a single elongated member, but is preferably made of an assembly of a plurality of string-like bodies 3, since this allows the artificial bait 1 to fly stably. When the string-like body 3 is made of the assembly, the string-like bodies 3 are not joined to each other except for the first end 31, and are in a free state without being restricted by each other. When the string-like body 3 is made of the assembly, the first end 31 of each string-like body 3 may be joined (integrated) so that all or part of the first end 31 of each string-like body 3 does not separate from each other, or they may not be joined to each other.

When the string-like body 3 is made of the above-mentioned aggregate, the number of the strings is not particularly limited, but is, for example, 2 or more, preferably 6 or more, and more preferably 10 or more. If the number of the string-like body 3 is too large, the artificial bait 1 becomes difficult to handle, so taking this into consideration, the number of the string-like body 3 is, for example, 16 or less, and preferably 12 or less.
In the illustrated example, the string-like body 3 is composed of eight string-like bodies 3. The eight string-like bodies 3 are composed of four strings extending from the rear to the front on one widthwise side (e.g., the right side) of the weight 6 and four strings extending from the rear to the front on the opposite widthwise side (e.g., the left side) of the weight 6. In each drawing, the string-like bodies arranged on one widthwise side of the weight 6 are indicated in parentheses by the reference symbol 3a, and the string-like bodies arranged on the opposite widthwise side of the weight 6 are indicated in parentheses by the reference symbol 3b.
However, the number of string-like bodies 3 is not limited to eight as shown in the illustrated example. In addition, the number of string-like bodies 3 arranged on one side and the opposite side in the width direction of the weight 6 is not limited to the same number, and the number of string-like bodies 3 arranged on one side may be more or less than the number of string-like bodies 3 arranged on the opposite side, or multiple string-like bodies 3 may be arranged only on one side or the opposite side. For stable flight of the artificial bait 1, it is preferable that the same number of string-like bodies 3 extend from the rear to the front on one side and the opposite side in the width direction of the weight 6.

As shown in Figures 4 and 5, the two string-like bodies 3 arranged on one side and the other side in the width direction (in the illustrated example, there are four pairs of two string-like bodies 3), are constructed by folding one long, thin part in half like a hairpin, and are therefore connected at the folded part X. This configuration is adopted because it simplifies the manufacture of the artificial bait 1 (attaching the string-like bodies 3, etc.). However, this is not limited to this, and multiple string-like bodies 3 (e.g. two or more) may be independent and not connected at the folded part X.

The shape of the string-like body 3 is not particularly limited as long as it is long and slender and has enough flexibility to hang down under its own weight when suspended in the air. For example, the string-like body 3 may be a long and slender string having a predetermined shape in cross section, a long and slender string having a rectangular shape in a plan view (in other words, a flat string). The predetermined shape in cross section may be a substantially circular, substantially elliptical, or substantially square rectangular shape, a substantially polygonal shape such as a substantially triangular or substantially hexagonal shape, a substantially star shape, or other irregular shape in a cross section cut in a direction perpendicular to the axial direction of the string-like body 3. Since the artificial bait 1 can be expected to fly stably, the string-like body 3 is preferably one having a predetermined shape in cross section, and a long and slender string-like body 3 having a substantially rectangular, circular, or elliptical cross section is more preferable, and a long and slender string-like body 3 having a substantially square, circular, or elliptical cross section is even more preferable. Fig. 6(a) shows a cross-sectional view of a string-like body 3 that is generally square in cross section, and Fig. 6(b) shows a cross-sectional view of a string-like body 3 that is generally circular in cross section. Fig. 6(c) is a perspective view including a cross section of a string-like body that is elongated and rectangular in plan view.

The thickness of each string-like body 3 is not particularly limited, but for appropriate flexibility, the diameter is, for example, 0.1 mm to 5 mm, and preferably 0.5 mm to 2 mm. However, the thickness of the string-like body 3 that is not substantially circular in cross section is the equivalent circle diameter.
The length of the string-like body 3 is not particularly limited, but is, for example, 20 mm to 200 mm, and preferably 50 mm to 80 mm, for stable flight of the artificial bait 1. The length of the string-like body 3 refers to the length from the edge of the first end 31 to the edge of the second end 32.
Furthermore, it is preferable that the length of the string-like body 3 is such that it is unlikely to become entangled with the line connected to the line connecting part 5 or the fishing hook 7 during flight or when reeling in underwater. Taking this into consideration, the length of the string-like body 3 can be determined in relation to the length 4L of the body 4 in the front-rear direction. For example, the length of the string-like body 3 is preferably 1/5 to 1/4 of the length 4L of the body 4 in the front-rear direction, and more preferably 1/2 to 4/5.
The length 4L in the front-rear direction of the body 4 of the artificial bait 1 of the present invention is, for example, 30 mm or more and 200 mm or less, and preferably 70 mm or more and 150 mm or less.
The material for forming the string-like body 3 is not particularly limited as long as it has flexibility, and may be rubber such as silicone rubber, thermoplastic elastomer, soft synthetic resin, etc., and preferably an elastic material with a high elastic modulus such as rubber or elastomer is used. The string-like body 3 may be formed using an elastic material with a low elastic modulus such as filaments spun from soft synthetic resin.

The string-like body 3 has a first end 31 attached to the middle of the artificial main body 2 in the front-rear direction, and a second end 32 which is a free end. The artificial bait 1 to which the string-like body 3 is attached in such an orientation is less likely to vary in flight distance each time it is cast, and can be cast stably a long distance.
Specifically, the string-like body 3 is attached to a midway portion of the pseudo body 2 in the front-rear direction, with the first end 31 facing the rear side of the pseudo body 2 and the second end 32 facing the front side of the pseudo body 2, and the second end 32 being a free end. The first end 31 of the string-like body 3 is an end on one side in the longitudinal direction of the elongated string-like body 3, and the second end 32 of the string-like body 3 is an end on the opposite side to the first end 31 in the longitudinal direction.
Only the first end 31 of the flexible string-like body 3 is attached to the pseudo body 2. Therefore, the first end 31 attached to the pseudo body 2 does not move (does not displace) at the attachment position, and the parts of the string-like body 3 other than the first end 31 can move freely (are displaceable).

The first end 31 of the string-like body 3 may be attached to the body 4, but is preferably attached to the weight 6, more preferably to the rear part of the weight 6, and even more preferably to the rear and upper part of the weight 6. By attaching the first end 31 of the string-like body 3 to the weight 6, and particularly to the rear part of the weight 6, it is expected that the swing of the center of gravity of the artificial bait during flight will be suppressed.

The attachment position of the first end 31 of the string-like body 3 may be any position on the pseudo body 2. As described later, in order to make the string-like body 3 less susceptible to air resistance during the early and middle stages of flight and during the later stages of flight, it is preferable that the attachment position of the first end 31 of the string-like body 3 be a portion closer to the front than the midpoint of the front-rear direction length 4L of the body 4, and further, when the front-rear direction length 4L of the body 4 is taken as 1, it is more preferable that the attachment position be within a range of 1/6 to less than 1/2 from the leading edge 42 of the body 4, and further more preferable that the attachment position be within a range of 1/5 to 1/3 from the leading edge 42 of the body 4.
In addition, when the first end 31 of the string-like body 3 is attached to a part of the pseudo-main body 2 other than the body 4 (for example, a weight 6), the attachment position of the first end 31 is determined by drawing a virtual line extending in the vertical direction from the first end 31 attached to the part other than the body 4, and the point where this virtual line intersects with the body 4 is deemed to be the attachment position of the first end 31 of the string-like body 3.

The first end 31 of the string-like body 3 may be fixedly attached to the artificial main body 2, or may be detachably attached to the artificial main body 2. In the illustrated example, the first end 31 of the string-like body 3 is detachably attached to the artificial main body 2. Since the string-like body 3 is detachably attached, if the string-like body 3 is damaged, such as torn, during use of the artificial bait 1, the string-like body 3 can be easily replaced.
There is no particular limitation on the method of attaching the first end 31 of the string-like body 3. When the first end 31 of the string-like body 3 is fixedly attached, the first end 31 is attached to the quasi-body 2 such as the weight 6 using an adhesive or the like. When the first end 31 of the string-like body 3 is detachably attached, the first end 31 is attached to the quasi-body 2 such as the weight 6 by, for example, fastening with a rubber or a string.
For example, the string-like body 3 is attached to an attachment portion 61 provided on the weight 6 .
In the illustrated example, the first end 31 of the string-like body 3 is detachably attached using a rubber tube 62. However, the method for detachably attaching the string-like body 3 is not limited to this.

Specifically, referring to Figs. 4 and 5, the weight 6 has an attachment part 61 to which the first end 31 of the string-like body 3 is attached. In addition, in order to make it difficult for the string-like body 3 provided at the rear part of the weight 6 to bend when it hits the corner of the weight 6, at least the part of the rear part of the weight 6 where the attachment part 61 is provided is chamfered. In the illustrated example, an inclined surface 69 is formed on one entire side or both entire side surfaces of the rear part of the weight 6, or on one side or both sides corresponding to the part where the attachment part 61 is provided. In other words, the entire rear part of the weight 6 or the part where the attachment part 61 is provided is formed to be wider as it moves forward. By forming the inclined surface 69 in this way, it is possible to prevent the string-like body 3 from bending in the width direction of the pseudo body 2 (without being hindered by the weight 6).

The attachment portion 61 is, for example, protruding from the rear portion (particularly, the rear and upper portion) of the weight 6. The attachment portion 61 is, for example, made of metal, and has an annular portion 611 and a rod portion 612 connected to the annular portion 611. The attachment portion 61 having the annular portion 611 and the rod portion 612 can be formed, for example, by bending the tip of a metal wire into a ring shape (metal rod with a ring). The attachment portion 61 is integrated with the weight 6, for example, by forming a locking portion (not shown) such as a return prevention protrusion on the rod portion 612 and locking the locking portion to a locked portion of the weight 6 or embedding the locking portion in the weight 6. The attachment portion 61 is provided such that a part of the rod portion 612 and the annular portion 611 protrude backward from the rear portion of the weight 6. However, the attachment portion 61 is not limited to such a configuration and can be appropriately changed.
The rubber tube 62 is attached to the annular portion 611 of the attachment portion 61. The inner diameter of the rubber tube 62 is smaller than the outer diameter of the annular portion 611. The rubber tube 62 is fitted onto the annular portion 611 while being expanded, and the expansion is released, whereby the rubber tube 62 tightly adheres to the annular portion 611. When the rubber tube 62 is expanded, it can be removed from the tubular body 611, and the rubber tube 62 can be detachably attached to the annular portion 611.

As shown in FIG. 7, a long part 30 about twice as long as one string-like body 3 is prepared. In the illustrated example, four long parts 30 are aligned and inserted into the annular part 611 of the attachment part 61. After inserting the long part 30 into the annular part 611 up to a point where the long part 30 is 1/2 the length, the long part 30 is bent at that point and the rubber tube 62 is expanded and fitted onto the annular part 611 of the attachment part 61. The rubber tube 62 is inserted up to the vicinity of the rod part 612 of the attachment part 61. In this way, as shown in FIG. 4 and FIG. 5, the first end 31 of the multiple string-like bodies 3 is fixed between the rubber tube 62 and the attachment part 61. The long part 30 is exactly the same as the string-like body 3 except that it is about twice as long as the string-like body 3, and is the material from which the string-like body 3 is formed. When the long part 30 is attached to the pseudo body 2, conceptually, the long part 30 becomes a string-like body 3.

The string-like body 3 is attached to the pseudo body 2 so that when the string-like body 3 is straightened, it is approximately parallel to the front-rear direction. The term "straightening the string-like body 3" refers to a state in which the axis of the string-like body 3 is approximately straight from the first end 31 to the second end 32 without bending the string-like body 3 near the first end 31 or in the middle of the longitudinal direction. As shown in FIG. 5, the string-like body 3 attached to the rear part of the weight 6 is slightly bent near the first end 31 due to the presence of the weight 6. As described above, even if the inclined surface 69 is formed in the rear part of the weight 6, the string-like body 3 is slightly bent due to the presence of the weight 6. Therefore, in this case, the term "straightening the string-like body 3" refers to a state in which the string-like body 3 is stretched in an approximately straight line from the first end 31 to the second end 32 without bending the string-like body 3 near the first end 31 or in the middle of the longitudinal direction, assuming that the weight 6 is removed.

Please note that the state of the string-like body 3 in Figures 1 to 3 is a design state. When the artificial bait 1 is in use, the flexible string-like body 3 can change into various shapes except for the first end 31 (although the first end 31 does not move). For example, Figure 8 shows the artificial bait 1 suspended in mid-air with its lower part facing downward (opposite the air), in which case the flexible string-like body 3 curves from near the first end 31 to the middle of its length due to its own weight, and the second end 32, which is the free end, hangs down.

<Using artificial bait>
The artificial bait 1 of the present invention is used by tying a line to the line connecting portion 5 and casting it into water (sea or fresh water) using a fishing rod.
9A to 9C are reference side views for explaining the flying posture of the artificial bait 1 of the present invention when it is thrown. The arrows in Fig. 9A to 9C indicate the traveling direction of the artificial bait 1.
As shown in Figure 9 (a), at the beginning of the flight after the artificial bait 1 is thrown, the artificial bait 1 flies with the lower part of the artificial main body 2, where the weight 6 is attached, facing toward the sky and with the front part, the line connection part 5, facing toward the front of the direction of travel in an attitude such that the fore-and-aft axis of the line 9 and the body 4 forms an approximately acute angle.
As shown in FIG. 2B, from the early stage of flight to the middle stage of flight, the artificial bait 1 gradually rotates in a side view with the line connection part 5 as the center point so that the rear part of the artificial main body 2 gradually faces the front of the direction of travel.
As shown in FIG. 1C, in the latter stage of flight, the artificial bait 1 flies with the rear part of the artificial main body 2 heading towards the front in the direction of travel.

In the artificial bait 1 of the present invention, the first end 31 of the string-like body 3 faces backward and the second end 32 faces forward, the first end 31 of the string-like body 3 is attached to the artificial main body 2, and the second end 32 (other than the first end 31) is a free end (see Figures 1 to 3). With such an artificial bait 1, the flight distance is unlikely to vary each time it is cast, and it can be cast stably over a long distance. The reason why the artificial bait 1 of the present invention has the above-mentioned effect is unclear, but the inventors speculate that it may be because of the following reasons.

FIG. 9 is a right side view for reference showing the change in flying attitude when the artificial bait 1 is thrown.
From the early stage of flight shown in Fig. 9(a) to the middle stage of flight shown in Fig. 9(b), the string-like body 3 is curved near the first end 31, and the second end 32 faces the opposite side to the leading side in the flight direction (the user side who cast the artificial bait 1). From the early stage of flight to the middle stage of flight, the artificial bait 1 changes its flight posture so that the fishing hook 7 side becomes the leading side in the flight direction. In the process of changing the flight posture in this way, the main force acting on the artificial bait 1 is the force of pulling it in the opposite direction to the flight direction by the line 9, but since the string-like body 3 that is curved near the first end 31 and protrudes to the side of the body 4 sways in the opposite direction to the flight direction, this string-like body 3 is more susceptible to air resistance, and a force in addition to the force of pulling it by the line 9 acts on the artificial bait 1. As a result, the artificial bait 1 quickly changes from the posture in the early stage of flight to the posture in the middle stage of flight. In particular, since the first end 31 of the string-like body 3 is attached toward the front of the body 4, it is expected that the curved string-like body 3 will increase the positive force acting on the artificial bait 1 (a force added to the pulling force by the line 9). The artificial bait 1 is most susceptible to air resistance during the change in attitude from the beginning to the middle of flight, so the artificial bait 1 of the present invention, which can shorten this period, will fly longer.

Next, from the middle flight to the latter flight shown in FIG. 1C, the artificial bait 1 flies with the weight 6 facing the water surface side (opposite to the air side) and the rear part (the side where the fishing hook 7 is provided in the illustrated example) toward the front in the flight direction. In the latter flight, the string-like body 3 that was curved from the early flight to the middle flight gradually becomes approximately straight from the first end 31 to the second end 32. That is, in the latter flight, the artificial bait 1 flies with its rear part toward the front in the traveling direction, so that the string-like body 3 that was curved near the first end 31 changes to a state in which it becomes approximately straight from the first end 31 to the second end 32 (as shown in FIG. 1 to FIG. 3), and the artificial bait 1 flies in this state. When the string-like body 3 becomes approximately straight from the first end 31 to the second end 32, the artificial bait 1 flies with its rear part toward the front in the traveling direction, and the string-like body 3 of the artificial bait 1 is less susceptible to air resistance. For this reason, it is believed that the attitude of the artificial bait 1 of the present invention during the latter part of flight is stabilized. Also, during the latter part of flight, the artificial bait 1 assumes an oblique attitude with the rear part slightly higher toward the sky than the front part, making it more susceptible to the effects of wind such as gusts of wind, but as described above, by making the string-like body 3 approximately straight and swaying, the string-like body 3 exerts a straightening effect that deflects the wind, and it is believed that the attitude of the artificial bait 1 during the latter part of flight is stabilized.
Since the combined period of the flight, early flight and mid flight of the artificial bait 1 is much shorter than that of the late flight, the posture of the artificial bait 1 of the present invention is stabilized in the late flight, so that the flight distance is less likely to vary with each throw, and the artificial bait 1 can be thrown stably a long distance.

In the above embodiment, the artificial bait 1 in which the fixed weight 6 is provided on the body 4 is illustrated, but the present invention is not limited to this.
Even in the artificial bait 1 of the present invention, as in Patent Document 1, for example, a weight storage space may be formed in the body, and a weight may be stored in the weight storage space (not shown). Such a movable weight is a weight embedded in the body 4. By providing the string-like body 3 to an artificial main body (type with a movable center of gravity) having such a movable weight, it can be cast stably and with a long flight distance. The structure of an artificial main body having a movable weight is widely known, and the artificial bait 1 of the present invention can be constructed by applying the string-like body 3 to an artificial main body having such a known structure.
