Description

The present invention relates to fishing lures. The fishing lure of the present invention, the angler casts the lure aiming at it, retrieves the lure from the point of landing, and reaches the point of the rod of the fishing rod. It provides a lure that can swim like a small fish. In particular, the present invention is characterized by the shape of the lure. Due to the shape of the lure, the lure rides under running water even when it is a so-called "only winding" retrieve operation. It is intended to provide a fishing lure that can swim like a fish and is less likely to fail in the movement of the lure even during retrieval from low speed to high speed.

Fishing lures are generally lumber, metal, synthetic resin, etc. processed into an appearance shape like a small fish and attached with a needle, and that shape is processed into a shape of shrimp, kaikai, insect, etc., Some are colored and imitated like the real thing. Among them, the minnow type lure made of wood or synthetic resin has a weight built-in inside the lure, and the weight serving as the center of gravity of the lure can be moved toward the head or tail of the lure. When casting, the lure is vertical and the weight is moving toward the tail and has the long throwing force (centrifugal force) necessary to fly far, and the lure is retrieved and swimming in water. At this time, since the lure is in a forward leaning posture in which the head is slightly lowered from the horizontal, the weight is moved toward the head and is formed to swim in water in the horizontal or forward leaning posture.

And in the posture of swimming in the water horizontally or in the forward leaning posture, the buoyancy is controlled by the material specific gravity and weight of the lure. And there is a suspend type that the lure is almost the same as water and stays in the water.

In addition, the minnow type lure has various shapes in order to swim in water while maintaining a horizontal or forward leaning posture and swimming like a real living small fish. Originally, the minnow type lure has a shape like a small fish in appearance, and it is a rod type pencil type that can swim like a real small fish in the water just by winding a reel. , There are lipless type without lip, normal type with lip, and diving type with long and big lip.

Thus, there is a document measuring and researching the posture and movement of a minnow type lure in water. "Measurement of lures using a circulating water tank" Mathematical Analysis Laboratory Research Record No. 1900, 2014, 105-109 (hereinafter referred to as Non-Patent Document 1), and according to this research record, artificially using a circulating water tank. Experiments are carried out with the lure fixed in the generated water stream and free to swim. The velocity of the water tank is 0.04 to 1.19 m / s. To investigate the posture and motion of the lure swimming in water, put a normal type lure with a lip or a lipless lure in a steady flow with a constant velocity. An experiment was conducted to track the marker attached to the lure. The markers are attached to the metal fittings of the lure head (probably a line eye), the tip of the lip, the base of the lip, the center of gravity, the tail, and the metal fittings of the tail (probably a hook eye of the tail), and the bottom and side surfaces of the observation tank. It is said that the tracking of the lure's posture and motion was obtained by performing tracking using the automatic tracking software from the video taken from, the lure's posture in water and the lure's unsteady state in water. The motion is analyzed from an experiment using a circulating water tank, and the hydrodynamic characteristics of the lure are decomposed into three elements of rolling, pitching, and yawing.

In other words, if the lure's posture / movement in running water is regarded as movement in water, rolling means that the lure swims with the head of the lure in front and the tail of the lure in the longitudinal direction of the lure. The horizontal central axis of the extending lure (referred to as the X axis) is a rotational motion component of the central axis of the lure, and the X axis of the central axis passes through the center of gravity of the lure (formed by the weight of the lure) and becomes a rotation axis or a tilt axis. The lure performs a so-called rolling motion by rotating around a horizontal central axis. Pitching means that the head and tail of the lure are rotated by rotating a rotation axis (referred to as Y axis) that intersects the horizontal center axis at a right angle on the center of gravity located behind the head of the lure. It rotates up and down. Further, yawing means that the vertical axis of rotation (referred to as the Z-axis) passing through the center of gravity of the lure rotates so that the head and tail of the lure move horizontally in the horizontal plane centering on the Z-axis. . Therefore, the unsteady and complicated movement of a lure having the shape of a small fish in water can be decomposed into the movements of three elements of rolling, pitching, and yawing.

Therefore, in Non-Patent Document 1, the hydrodynamic characteristics of the lure in water were investigated by a marker tracking experiment, and a noteworthy thing is that the yaw of the lure is centered on the knot of the fishing line and is left and right in the horizontal plane. There is a record that yawing around the center of gravity of the lure was seen instead of a simple swinging thing. In addition, the lure makes periodic movements in water, but when the lip is removed, the period and swing range change greatly, and the characteristics of the lure movement change depending on the presence or absence of the lip. It can be seen that the dominant frequencies of rolling and yawing coincide, and under certain conditions, the second harmonic of rolling and pitching is the dominant frequency. In the unsteady state of the flow in the circulating water tank, there were many sharp increases and decreases in the dominant frequency with respect to the Reynolds number. The number of times has decreased. Upward flow along the lip angle is seen in front of the lip, and separation is forcibly performed. There is a large vertical vortex structure and vortex pairs in this separation region, and the vortex pairs become more unstable as the Reynolds number increases. A lure that swims in water generates vortices alternately from the left and right sides of the lip in accordance with rolling and yawing from the left and right sides of the lip. It is suggested that by changing the lip shape, it is possible to make lures with arbitrary movement characteristics according to the target fish.

Therefore, in Non-Patent Document 1 described above, the combined action of rolling, pitching, and yawing is a factor that causes the lure to swim in the water while maintaining a horizontal or forward leaning posture and swimming like a real living small fish. It is understood that it is being done by. In addition, the lure used for measurement in Non-Patent Document 1 is a normal type lure that has the appearance of a small fish and has a lip on the lower jaw. In measurement, a lipless type with the lip removed for comparison. We also measure the lure of the lure as a measurement target, and both the normal type lure and the lipless type lure make a combined action of rolling, pitching, and yawing in the circulating water tank, which is the hydrodynamic characteristic of the lure. I can understand that.

Further, in the prior art document, the one in which the movement of the lure in water is considered and its operation defect is improved is disclosed in Japanese Patent No. 5946146 (hereinafter referred to as Patent Document 1). The invention of Patent Document 1 is a lure having a configuration in which a plate-shaped blade is attached to the tail portion of a lure body imitating the body of a small fish via a blade eye, and the blade of the lure receives a water flow when retrieved. It swings while twisting about the longitudinal direction, and it has the view that yawing repeatedly occurs in water, and since yawing is similar to the movement of small fish, the target fish react to this movement and the fish collecting effect is It is an invention to be obtained.

Then, in the invention of Patent Document 1, in the following two embodiments, specific proposals are made to suppress excessive yawing to prevent the behavior of the lure body from being broken.
That is, in Patent Document 1, paragraph numbers 0051 and 0052 are included.
Paragraph number 0051
The hooks (41) and (42) are attached symmetrically with respect to the lure body (2). Therefore, the resistance force due to the water flow is applied to the two needle portions (44) of the hook (41) substantially uniformly. Similarly, the resistance force due to the water flow is applied to the two needle portions (44) of the hook (42) substantially uniformly. The hooks (41) and (42) also serve to regulate the water flow. As a result, the hooks (41) and (42) exert a function of stabilizing the posture of the lure body (2). Therefore, the behavior of the lure body (2) is prevented from being broken, and the yawing of the lure body (2) continues.
Paragraph number 0052
Further, since the hook (41) is attached to the back side of the lure body (2) and the hook (42) is attached to the abdominal side, the resistance force applied to the upper side of the lure body (2) and the lower side thereof. It is balanced with the resistance. Therefore, the posture of the lure body (2) is prevented from being disturbed in the vertical direction, which also prevents the behavior of the lure body (2) from being broken. "
By attaching hooks to the lure body symmetrically or by attaching it up and down, the movement of the lure is stabilized, and the lure does not jump out of the surface of the water in the posture and movement, or the lure catches. It is intended to prevent a phenomenon in which the movement of the lure breaks down, such as no repeated swimming.

Thus, in Non-Patent Document 1 described above, an experiment in a circulating water tank is analyzed, and the hydrodynamic characteristics of the minnow type lure are decomposed into three elements of rolling, pitching, and yawing. For example, it is very significant from a hydrodynamic point of view to apply the lure cast and retrieve it in a complicated tidal current such as rock fishing, but it is very significant from a hydrodynamic point of view. In addition, in the invention of Patent Document 1, in paragraph 0051, a measure for causing failure in the behavior of the lure body is shown. This is to attach the hook symmetrically with respect to the lure body and to attach the two needle portions of the hook. There is a description that the yawing that occurs too much is suppressed by applying the resistance force due to the water flow approximately evenly. Paragraph number 0052 describes that hooks are attached to the back side and the abdomen side of the lure body to prevent the lure body from being vertically disturbed. As an example, one that suppresses excessive pitching-like movement is described. As shown, an invention having a configuration in which the breakdown of the behavior due to the yawing and the pitching is arranged symmetrically or is adjusted by the resistance force due to the substantially even water flows attached above and below is presented.

Patent No. 5946146 Patent Publication

Thus, the present invention does not swim the lure in a constant flow like a circulating water tank, but as an example of receiving the flow from various directions when the lure is cast in water and swims in the water by retrieve, for example, It is assumed that you will swim in the current such as rock fishing. In FIG. 1, 1, 1a, 1b, 1c, 1d, ... Are lures that carry out the present invention, 2 are rods, 3 are reels, 4 are lines, 5 is a rod tip, and white arrows are It shows the flow and strength of the water stream. The lure 1 is cast by a fisherman standing on the rock like a lure 1a, and it is retrieved by the reel 3 in the tide and operated to return to the rod tip 5. However, when the lure 1 is cast into the tide, the lure changes its tide. It meanders under the influence of a non-directional flow indicated by the hollow arrow. Further, it is important for the lure to swim in the tidal current without breaking down like the lures 1a, 1b, 1c, 1d, ... Even if the lure retrieves at such a speed as to meander.

However, with conventional lures, due to uncertain flow, the lure moves beyond the permissible range of rolling, pitching, and yawing, causing the lure to jump out of the surface of the water and prevent the lure from swimming. It had a major drawback that it caused a phenomenon in which the movement of the lure collapsed, such as no repeated swimming. INDUSTRIAL APPLICABILITY The present invention has a feature in the shape of the lure, which allows it to swim like running a real small fish by riding in running water even if it is a simple retrieve and the lure can be used in retrieves from low speed to high speed. It is intended to provide a fishing lure that does not move easily.

One example of the fishing lure of the present invention is to manufacture a lipless type lure body imitating a small fish having a proboscis at the tip by cutting wood such as cypress and balsa, and the lure body has a cross section inside. A semi-circular gutter-shaped object is engraved to form a weight rolling hole for weight attachment. A front rolling hole and a rear rolling hole communicate with each other in the weight rolling hole, and three spherical weights are rotatably installed in the communicating front and rear rolling holes. ing. Then, the spherical weight installed in the weight rolling hole rolls in the rear rolling hole provided in the fish tail part along with the casting motion of the lure to enhance the long throwing ability of the lure, and at the time of landing the lure. The proboscis, which is the tip, floats up near the water surface, and the lure body is configured to be maintained perpendicular to the water surface.

In addition, when the lure body is lifted vertically, when the lure is retrieved, the spherical weight rolls from the rear rolling hole into the front rolling hole, and the lure body floats up in water like a ship. The floating state of the lure body depends on the weight of the hook plus the weight of the lure, but it has a shape in which the proboscis, which is the tip of the lure, tilts into the water and sinks into the surface of the water.

Furthermore, the luer body is provided with a wire passage groove that passes from the proboscis to the lower abdomen and faces the tail, and a wire processing member made of stainless steel or the like is fitted in the wire passage groove. Has been done. The wire processing member has a ring-shaped line eye that protrudes from the lure body to the outside in the proboscis portion of the lure body, and the other end protrudes to the outside in the lower abdomen of the lure body to form two U-shapes. After forming the hook hanger that it has, it extends to the tail to form a ring-shaped heaton.

The lure body of the present invention is housed in a front rolling hole and a rear rolling hole communicating with a plurality of spherical weights to set the balance and floating direction for the lifting force of the lure body, and the wire processing member. Line eye, hook hanger, heaton is formed, and the line is connected to the line eye via a ring and a snap, and the line is connected to the reel provided on the bat of the fishing rod via the fishing tip. There is. The hook hanger arranged on the lower abdomen of the lure body is provided with a hook via a ring, and the heaton at the tail of the lure body is provided with a rear hook via a ring. And, the hook hanger and heaton of the wire processing part provided on the lower abdomen of the lure body, and the hook and rear hook provided on the hook hanger and heaton play a role of ballast, and affect the buoyancy and the depth of dive while maintaining the center of gravity. As it increases the resilience, the angler can select the hook size and weight to adjust the castability of the lure body when casting, and the depth of the lure in the water during retrieval and the lure. The posture of the main body can be taken into consideration, but regarding the influence of water flow in water, as in the present invention, a device near the lower jaw of the tip of the lure body is added to control excessive movement due to rolling, pitching and yawing. It swims underwater so that the lure does not collapse.

In the present invention, to explain in detail the shape of the important lure, the lure body made of wood or synthetic resin and imitating the shape of a fish has a pair of fish eyes drawn at the tip that is the direction of travel by the retrieve, and a proboscis on the front. There is an upper jaw provided on the upper part of the mouth and the snout and a lower jaw provided on the lower part of the snout, and the fish head composed of the pair of fish eyes, the snout, the upper jaw and the lower jaw constitutes the tip of the lure body. Forming a body having a back portion, both side portions and a lower abdominal portion continuous to the tip portion of the lure body, and forming a tail portion at the rear portion of the body to form the shape of the lure body; A ring-shaped line eye shaped with a wire of the same type, one or two U-shaped hook hangers shaped with a stainless steel wire on the lower abdomen, and a stainless steel wire on the tail. Formed as a ring-shaped heaton shaped with ears, it has a semi-conical shape with a length just before the center of gravity of the lure at the rear of the lower jaw of the head of the lure body, and its apex The present invention provides a fishing lure characterized by carving a steering groove formed of a semi-conical recessed groove that is tapered toward the tail.

Further, as an example of the present invention, in a lure body made of wood or synthetic resin and imitating the shape of a fish, a fish head composed of a pair of fish eyes, a proboscis, an upper jaw, and a lower jaw has a tip portion of the lure body. A right-angled triangular pyramid recessed groove having a right-angled triangular pyramid shape with a length about the front of the center of gravity of the lure in the rear part of the lower jaw of the head part of the lure body, with its apex directed toward the tail direction. The present invention provides a fishing lure characterized by being engraved with a steering groove.

Furthermore, as an example of the present invention, in a lure body made of wood or synthetic resin and imitating the shape of a fish, a fish head composed of a pair of fish eyes, a snout, an upper jaw, and a lower jaw has a tip portion of the lure body. A steering groove having a rectangular cross section or a U-shaped groove with a length about the length before the center of gravity of the lure is formed in the rear of the lower jaw of the head of the luer body. It provides fishing lures.

Then, as an application example of the present invention, in a lure body made of wood or synthetic resin and imitating the shape of a fish, a fish head composed of a pair of fish eyes, a snout, an upper jaw, and a lower jaw has a tip portion of the lure body. And forming a steering groove composed of two semi-conical recessed grooves or two right triangular pyramid recessed grooves in parallel with the rear part of the lower head jaw of the tip of the luer body. The present invention provides a fishing lure, characterized in that two steering grooves each having a quadrangular groove or a U-shaped groove in cross section are arranged in parallel.

Thus, the present invention envisions swimming the lure in a tidal current, such as surf fishing, which receives flow from different directions. According to the present invention, when a lure is cast into a tidal current, the lure is affected by a non-directional water flow in the tidal current. During retrieval of the lure, the lure swims with the lure head in front and the tail behind. Is the horizontal center axis (X-axis) of the lure that extends forward and backward in the longitudinal direction of the lure and passes through the center of gravity, which serves as a rotation axis or an inclination axis, and the lure rolls around the horizontal center axis to perform rolling rolling motion. is there. The tidal current with no direction acts on the lure as a flow that exceeds the allowable rolling angle of lateral hitting and acts to overturn the lure, but it is provided behind the head under the jaw of the tip of the lure body. The cross-sectional shape of the semi-conical recessed groove, the right-angled triangular pyramid recessed groove, and the steering groove, which has a square cross section or a U-shaped groove, catches the water flow and prevents the lure from overturning even if the allowable rolling angle is exceeded. It has a rolling continuation function that restores and stabilizes the posture of the main body, and has a configuration in which the lure does not fail when rolling in water.

In addition, the lure of the present invention has a rotation axis (Y axis) that intersects the horizontal center axis at a right angle to the horizontal center axis about the center of gravity of the head of the lure during retrieval. The pitching motion in which the part and the tail rotate up and down is controlled, and the lure constantly performs the pitching motion by receiving the water flow, but from the rear part of the lower head of the tip part to the front of the center of gravity of the lure. In the case of a semi-conical concave groove having a length, a right-angled triangular pyramid concave groove, or a steering groove having a square cross section or a U-shaped groove in cross section, rectification can always be generated in the longitudinal direction at the lure tip. It has a configuration in which retrieval in the straight ahead direction is continued, the posture of the lure is controlled, the pitching motion exceeds the allowable range, and the lure does not fail.

Further, during retrieval, the lure of the present invention rotates about the vertical axis of rotation (Z axis) passing through the center of gravity of the lure, so that the head and tail of the lure are horizontally leveled about the Z axis in the horizontal plane. During the tidal current, the lure may move beyond the permissible yawing angle.At this time, a semi-conical concave groove or a right angle formed in front of the center of gravity of the lure. In a triangular pyramid recessed groove or a steering groove having a square cross section or a U-shaped groove in cross section, the posture of the lure tip is stabilized by generating straightening in the longitudinal direction at the tip of the lure, and yawing of the lure is performed. The function of controlling the posture so that the rotation by does not exceed the allowable yawing angle is exerted, and it is configured so that the lure does not fail due to yawing.

In the present invention, the semiconical concave groove, the right triangular pyramid concave groove, the rectangular groove, or the U-shaped groove is formed in the length from the tip of the lure body, the rear of the lower jaw to the front of the center of gravity of the lure. By engraving the steering groove consisting of V-shaped groove etc., the lure operates within the range that does not exceed the allowable range of rolling, pitching, and yawing even in complicated water movement such as tidal current, and the movement of the lure is on the water surface. It has improved the major drawbacks that cause the phenomenon that the movement of the lure collapses, such as when you jump out of it and there is no swimming or when the lure turns over and there is no swimming. And, the present invention enables swimming with a combined movement of rolling, pitching, and yawing like a real living small fish by riding in running water even with a simple retrieve, and in a range from low speed to high speed. It has become possible to provide fishing lures that do not cause the lure's movement to collapse even during retrieval.

The hook hanger arranged on the lower abdomen of the lure body is provided with a hook via a ring, and the heaton at the tail of the lure body is provided with a rear hook via a ring. And, the hook hanger and heaton of the wire processing part provided on the lower abdomen of the lure body, and the hook and rear hook provided on the hook hanger and heaton play a role of ballast, and affect the buoyancy and the depth of dive while maintaining the center of gravity. As it increases the resilience, the angler can select the hook size and weight to adjust the castability of the lure body when casting, and the depth of the lure in the water during retrieval and the lure. The posture of the main body can be taken into consideration, but regarding the influence of water flow in water, as in the present invention, a device near the lower jaw of the tip of the lure body is added to control excessive movement due to rolling, pitching and yawing. Then, the so-called lure swims underwater so as not to fail.

Thus, in the present invention, the important shape of the lure will be described in detail.In a minnow type lure that is made of wood or synthetic resin and imitates the shape of a fish, the body of the lure forming the shape of the fish is cast in water and retrieved. Then, the head of the lure body and the proboscis are provided at the tip part, which is the direction of travel, the upper jaw and the lower jaw are provided at the upper part of the proboscis, and the head composed of the upper jaw and the lower jaw. The body forms a tip of the lure body, forms a body having a back, both side surfaces, and a lower abdomen continuously from the tip of the lure body, and forms a tail at the end of the body to form the lure body. A semi-conical recessed groove is formed on the rear portion of the lower jaw at the tip of the lure body and has a taper in a semi-conical shape with its apex facing toward the tail portion, and the semi-conical recessed groove is formed in the luer body. Fishing with steering groove It is to provide the use lures.

Further, the present invention is a lure body made of wood or synthetic resin that imitates the shape of a fish, wherein the tip of the lure has a taper in the shape of a right-angled triangular pyramid at the rear of the lower jaw, and its apex is directed toward the tail. The present invention provides a fishing lure which is provided with a right-angled triangular pyramid-shaped recessed groove and uses the right-angled triangular pyramid-shaped recessed groove as a steering groove of a lure body.

Furthermore, the present invention is a lure body made of wood or synthetic resin that imitates the shape of a fish, wherein the tip of the lure has a quadrangular pyramid taper on the rear part of the lower jaw, and its apex is carved toward the tail. The present invention provides a fishing lure in which the above-mentioned quadrangular pyramid-shaped recessed groove is provided and the quadrangular-pyramidal recessed groove is used as a steering groove of the lure body.

Thus, the present invention envisions that the lure swims in a tidal current such as surf fishing that receives currents from various directions. In the present invention, when the lure is cast into a tidal current, the lure is affected by a non-directional flow in the tidal current. In the tide, the lure swims in a realistic manner like a small fish because the lure swims with the head in front and the tail behind, and the lure extends back and forth in the longitudinal direction of the lure and passes through the center of gravity. The horizontal center axis (X axis) of the above is the rotation axis or the tilt axis, and it is also a major factor that the lure rolls around the horizontal center axis to perform a rolling rolling operation. And, the directional current with no direction acts on the lure as a flow that exceeds the allowable rolling angle of lateral hitting and operates to overturn the lure, but it is provided behind the head lower jaw part at the tip of the lure body. A continuous rolling function that restores and stabilizes the posture of the lure body so that the cross-sectional shape of the steering groove, such as a semi-conical recessed groove or a right-angled triangular pyramid recessed groove, becomes caught and does not overturn even if the allowable rolling angle is exceeded. have.

The pitching motion in which the part and the tail rotate up and down is controlled, and the lure constantly performs the pitching motion by receiving the water flow, but from the rear part of the lower head of the tip part to the front of the center of gravity of the lure. In a steering groove consisting of a semi-conical concave groove with a length or a right-angled triangular pyramid concave groove, etc., straightening can always be generated in the longitudinal direction at the tip of the lure, so retrieve in the straight direction is continued and the lure posture The pitching movement is controlled and continued within an allowable range.

Further, during retrieval, the lure of the present invention rotates about the vertical axis of rotation (Z axis) passing through the center of gravity of the lure, so that the head and tail of the lure are horizontally leveled about the Z axis in the horizontal plane. When performing a yawing motion, the lure may move beyond the permissible yawing angle in a tidal current.At this time, a semi-conical recess groove provided in front of the center of gravity of the lure, or In the steering groove composed of a right-angled triangular pyramid concave groove, etc., the function of stabilizing the posture is achieved so that the allowable yawing angle is not exceeded by generating rectification in the longitudinal direction at the tip of the lure.

In the present invention, a steering groove formed of a semi-conical recessed groove, a right triangular pyramid recessed groove or the like is engraved in a length from the front end of the lure body, the rear part of the lower jaw to the front of the center of gravity of the lure. This allows the lure to operate within a range that does not exceed the allowable range for rolling, pitching, and yawing, even in water that makes complicated movements such as tidal currents, and the lure moves out of the surface of the water to prevent swimming, or the lure is upset. It has improved a major drawback that causes the phenomenon that the movement of the lure collapses, such as no swimming. In addition, the present invention is capable of swimming with a combination of rolling, pitching, and yawing like a real living small fish by riding in running water even with a simple retrieve operation, and retrieve from low speed to high speed range. However, it has become possible to provide fishing lures that do not cause the lure's movement to collapse.

And, the above-mentioned embodiment of the present invention has been described with reference to an example in which it is implemented in a pencil rod type, but it can be implemented in a normal minnow with a lip and a minnow lure of a lipless type, and its effect is great. There is something.

The present invention is not an example of swimming a lure in a steady flow like a circulating water tank, but an example in which the lure is cast in water and receives a flow from various directions when swimming in water by retrieve, such as surf fishing. It is supposed to swim in the tide. In FIG. 1, 1, 1a, 1b, 1c, 1d, ... Are lures that carry out the present invention, 2 are rods, 3 are reels, 4 are lines, 5 is a rod tip, and white arrows are It shows the flow and strength of the water stream. The lure 1 is cast by a fisherman standing on the rock like a lure 1a, and it is retrieved by the reel 3 in the tide and operated to return to the rod tip 5. However, when the lure 1 is cast into the tide, the lure changes its tide. It meanders under the influence of a non-directional flow indicated by the hollow arrow. The same applies to fishing in stormy weather, because the lure 1 meanders in the water current under the influence of the non-directional flow indicated by the white arrow, so the lure is a slow-moving trieve. However, it is important for the bait to swim in the tidal current without breaking down like the lures 1a, 1b, 1c, 1d, ....

In addition, FIG. 2 is a hydrodynamic analysis of the posture and movement of the retrieved lure 1 in the water flow. The center of gravity CG of the lure 1 is centered in the longitudinal direction of the lure. Let the X-axis be the rotation axis that rotates horizontally around the axis, the Y-axis be the rotation axis that intersects the horizontal center rotation axis X at a right angle on the center of gravity, and the Z-axis be the vertical rotation axis that passes through the center of gravity of the lure. The lure 1 becomes a rotation axis or a tilt axis and rotates around the X axis to perform a so-called rolling rolling R motion, and as the Y axis rotates, the head and tail of the lure 1 move up and down. This is a pitching P motion that rotates, and the yawing Y motion is a motion in which the lure 1 horizontally moves around the Z axis by rotating the Z axis.

Therefore, the movement of the lure 1 in the water is swimming in water like a small fish due to the combined movement of the rolling R movement, the pitching P movement, and the yawing Y movement. If it collapses due to a strong flow from a certain direction, lure 1 will collapse and the movement of the lure jumps out of the water surface and there will be no swimming, or the lure will turn over and no swimming will occur.

Thus, when lure fishing is performed using the lure 1, as shown in FIGS. 2 (A) and 2 (B), the line eye 8 provided on the proboscis 7 of the lure body 6 is snapped via the ring 9. 10 is attached (the line may be directly connected to the line eye), and the line 4 is connected to the snap 10. Although not shown in FIG. 2A, the other end of the line 4 is connected to a reel attached to the butt of the rod via a rod tip guide of the fishing rod. In FIG. 2 (A), hooks 12 are attached to the hook hangers 11a and 11b of the lure body 6 via the ring 9, respectively, and the heatons 14 provided on the tail portion 13 of the lure body 6 are also attached.

Since the spherical weights 21a, 21b, 21c built in the lure body 6 roll toward the rear rolling hole 20 side during casting, the cast lure body 6 moves the tip portion 15 of the lure body near the water surface 22. The luer main body 6 is configured to be floated up and maintained perpendicularly to the water surface 22. When the luer main body 6 is lifted vertically, the spherical weights 21a, 21b, 21c are rear-rolled when the lure main body 6 is retrieved. The lure body 6 can float in the water near the water surface 22 and rise up by rolling from the moving hole 20 into the front rolling hole 19. FIG. 2B shows a state in which the lure body 6 is retrieved to swim in the direction of the rod tip. In the first embodiment, the head 18 serving as the tip portion 15 of the lure body is attached to the lower jaw 16. By forming the steering groove 24 by carving the semi-conical recessed groove 23 in the rear portion, it is possible to prevent vortex and turbulent flow from being generated at the head portion 18 of the lure body 6 located on the front surface in the traveling direction by the retrieve. , The semi-conical recessed groove 23 generates positive rectification as shown by an arrow S (shown in FIG. 3 (B)), so that the fish head 18 of the lure body 6 always moves straight toward the rod tip by the retrieve. The fact that the rectification S can be generated at the tip portion 15 of the lure body is controlled so that even if excessive pitching or yawing occurs in the water, the head 18 is directed straight in the rod tip direction due to the generation of the rectification S. Then The attitude of the over body 6 can exhibit a function to stabilize.

Further, the lure of the present invention is supposed to swim in a tidal current (shown in FIG. 1) such as surf fishing which receives currents from various directions.
