Mode for Carrying Out the Invention

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] FIG. 1 is a right side view showing a metal squid 1 as a squid fishing imitation bait according to an embodiment of the present invention. FIG. 2 is an exploded perspective view showing the metal squid 1, and FIG. 3 is a vertical cross-sectional view showing the metal squid 1. FIG. 4 is a bottom view showing the metal squid 1, and FIG. 5 is a rear view showing the metal squid 1. Further, FIG. 6 is a perspective view of the tail body (lower half) 22 of the metal squid 1, and FIG. 7 is a schematic view showing the usage state of the metal squid 1.

[0013] <External Configuration> Specifically, this metal sinker 1 is a so-called lead sinker for squid, which is used for boarding a fishing boat or the like and mainly targeting squids such as flying squids, spear squids, and Japanese flying squids (also called Japanese common squid, red squid, white squid, and round squid) offshore. Also, there are multiple variations of the metal sinker 1 with different weights, such as No. 15 (about 56.25 g), No. 20 (about 75.00 g), No. 25 (about 93.75 g), No. 30 (about 112.50 g), etc. And the metal sinker 1 is composed of a rod-shaped sinker body 2 made of a metal material with a relatively large specific gravity such as lead, tungsten, or iron, a cloth material 3 covering this sinker body 2, and a hook (umbrella-shaped needle body: hook) 4 formed by opening a wire with a sharp tip in an umbrella shape.

[0014] Here, in the following description, for the metal sinker 1, one end (tip side) at one end in the longitudinal direction (front-rear direction) of the sinker body 2, which mimics the head of a small fish, is called the head side (head end) 2A, and the other end in the longitudinal direction (base end side) on the opposite side of this head side 2A is called the tail side (tail end) 2B. Also, one side of the sinker body 2 that mimics the abdomen of a small fish is called the belly side (ventral side) 2C, and the other side of the sinker body 2 that mimics the back of a small fish, which is the other end in the width direction (up-down direction, height direction) on the opposite side of this belly side 2C, is called the back side (dorsal side) 2D.

[0015] The main body 2 of the fishing tackle is formed in an elongated columnar shape imitating a small fish, and has a head body (upper half) 21 that constitutes a portion corresponding to about one-half of the head side 2A of the small fish, and a tail body (lower half) 22 that constitutes a portion corresponding to about one-half of the tail side 2B of the small fish. The head body 21 is provided with a head portion 21a having a shape imitating the head of a small fish on the tip side, and a body portion 21b is integrally formed on the tail side 2B of the head portion 21a. Further, the head portion 21a is formed in a tapered shape toward the head side 2A, and at the tip of the head portion 21, an annular line eye (connection portion, eyelet) 23 for connecting a connecting tool such as an end of a fishing line or a snap swivel S2 connected to the tip of the fishing line is provided. As shown in FIGS. 1 to 4, this line eye 23 is attached along the height direction from the belly side 2C to the back side 2D of the head body 21a and has a shape penetrating in the width direction of the head body 21a.

[0016] In addition, concave eye fixing portions (eye portions) 21c for attaching and fixing eye seals (eyeball seals) 24 having a shape imitating the eyes of a fish are respectively provided on both side surfaces in the width direction of the head portion 21a. These eye fixing portions 21c are formed by recessing both side surfaces in the width direction of the head portion 21a, and in a state where the eye seals 24 are attached and fixed to these eye fixing portions 21c, the eye seals 24 do not protrude outside the outer surface of the head portion 21a. Further, as shown in FIGS. 1 and 2, these eye fixing portions 21c are respectively provided at positions closer to the back side 2D than the belly side 2C of the head portion 21a.

[0017] Furthermore, the body portion 21b of the head body 21 has an elliptical cross-section (oval shape) with a height dimension larger than the width dimension, and is formed in a columnar shape smaller than the diameter dimension in the width direction and the diameter dimension in the height direction on the proximal end side of the head portion 21a. And at the connecting portion between this body portion 21b and the head portion 21a, a locking groove portion 21d with a concave cross-section is provided along the edge portion on the tail side 2B of the head portion 21a. This locking groove portion 21d is provided annularly over the entire circumference in the circumferential direction between the head portion 21a and the body portion 21b. Also, on the belly side 2C of the body portion 21b, a mounting groove portion (groove portion) 21e in the shape of a continuous concave groove in cross-section is provided from the head side 2A to the tail side 2B of this body portion 21b. This mounting groove portion 21e is formed linearly on the belly side 2C of the body portion 21b and is provided across the locking groove portion 21d provided on the head side 2A of this body portion 21b.

[0018] Also, the end face on the tail side 2B (proximal end side) of the body portion 21b is a flat vertical plane perpendicular to the direction from the head side 2A to the tail side 2B (longitudinal direction). The end face on the tail side 2B of this body portion 21b is formed in an elliptical shape with the direction from the belly side 2C to the back side 2D (height direction, vertical direction) as the major axis direction. Also, at the center position of the end face on the tail side 2B of the body portion 21b, a fitting concave portion (opening portion) 21f for fitting and fixing the proximal end side of the cutter 4 is provided. As shown in FIG. 2, this fitting concave portion 21f has a concave portion main body 21g with a polygonal cross-section, for example, a regular octagonal cross-section.

[0019] And on the inner peripheral surface of the recess main body 21g, a plurality of, for example, eight cannula fixing grooves 21h are provided at equal intervals in the circumferential direction of the recess main body 21g. Each of these cannula fixing grooves 21h is formed linearly along the axial direction of the recess main body 21g. Here, as shown in FIGS. 1 to 5, the cannula 4 fixed to the fitting recess 21f is an intermediate cannula (intermediate umbrella-shaped needle body) 4A formed of a plurality of, for example, eight needle materials 41 formed of a single wire material (stainless steel wire). And the needle materials 41 constituting this intermediate cannula 4A are formed by bending the intermediate part of a single wire material by 180°, and further bending each of the both side parts of this bent wire material by about 120° in the same direction at the intermediate part and so that the angle between these both side parts becomes 15°, and further, the tip parts of each of these both side parts are sharply cut to form needle-like parts 41a.

[0020] Specifically, the bent part of these needle materials 41 by 180° is a fixed part (base end part) 41b, and the needle tip parts 41a of a plurality of, for example, eight needle materials 41 are respectively projected in an umbrella shape in the radial direction, and the fixed parts 41b of each of these needle materials 41 are formed into a cylindrical cylindrical part 41c in a state of being arranged in a circumferential shape. Then, this cylindrical part 41c is inserted into each cannula fixing groove 21h of the fitting recess 21f of the body part 21b and attached, and it becomes a configuration of an intermediate cannula 4A in which a plurality of needle-like parts 41a project in an umbrella shape from the base end side of the cylindrical part 41c.

[0021] Here, the outer diameter dimension of the cylindrical part 41c of the intermediate cannula 4A is configured to be equal to the inner diameter dimension of the fitting recess 21f including each cannula fixing groove 21h of the head body 21. Further, in the fitting recess 21f, in a state where the fixed parts 41b of each needle material 41 are inserted into each of the cannula fixing grooves 21h of this fitting recess 21f, the head side 2A of a substantially cylindrical joint body (connecting material) 5 for fixing these fixed parts 41b to the body part 21b is fitted and attached.

[0022] And, like the sutte body 2, this joint body 5 is made of a metal material with a relatively large specific gravity, such as lead, tungsten, or iron, and is formed into a polygonal cross-section, for example, a regular octagonal cross-section, according to the number of needle materials 41 fixed by this joint body 5. Further, the joint body 5 has a shape such that the outer diameter dimension of the head side 2A of the joint body 5 is equal to the inner diameter dimension of the cylindrical portion 41c of the middle cannula 4A and the inner diameter dimension of the fitting recess 21f of the head body 21.

[0023] Furthermore, an adhesive groove portion 5a with a concave cross-section is provided over the circumferential direction at a position closer to the head side 2A of the joint body 5. Also, at the end of the tail side 2B of this joint body 5, a cylindrical fitting convex portion 5b with the end of the tail side 2B of the joint body 5 reduced in diameter in a stepped shape is provided concentrically. And, at a position on the head side 2A from the fitting convex portion 5b on the tail side 2B of this joint body 5, an adhesive groove portion 5c with a concave cross-section is also provided over the circumferential direction.

[0024] And, the tail body 22 of the sutte body 2 is configured to be fitted and attached to the tail side 2B of the joint body 5. In short, the joint body 5 is configured to connect the head body 21 and the tail body 22 while positioning and fixing the middle cannula 41. And, the tail body 22 has a shape that gradually becomes thinner (reduced in diameter) from the head side 2A toward the tail side 2B. Therefore, the belly side 2C of the tail body 22 has a shape inclined at a larger inclination angle than the back side 2D of this tail body 22. Also, on the belly side 2C of the tail body 22, a continuous mounting groove portion (groove portion) 22a with a concave cross-section is provided from the head side 2A to the tail side 2B of the tail body 22. This mounting groove portion 22a is formed linearly on the belly side 2C of the tail body 22 and penetrates through the head side 2A and the tail side 2B of this tail body 22, respectively.

[0025] Further, the end face of the head side 2A (tip side) of the tail body 22 is a flat vertical plane perpendicular to the direction from the head side 2A toward the tail side 2B. Here, the end face of the head side 2A of this tail body 22 is formed in an elliptical shape (oval shape) that is substantially equal to the shape of the end face of the tail 2B side of the head body 21. And, on the end face of the head side 2A of the tail body 22, the tail side 2B of the joint body 5 is fitted, and a fitting recess (opening) 22b for fixing the tail body 22 to the head body 21 via this joint body 5 is provided. The inner diameter dimension of this fitting recess 22b is formed to be equal to the outer diameter dimension of the tail side 2B of the joint body 5.

[0026] And, as shown in FIGS. 3 and 6, the fitting recess 22b has a recess main body 22c with a polygonal cross section, for example, a regular octagonal cross section, and at the bottom of the tail side 2B of this recess main body 22c, a concave fitting step portion 22d having a circular cross section for fitting the fitting convex portion 5b of the joint body 5 is provided concentrically. In short, the middle cannula 4A inserts the cylindrical portion 41c of this middle cannula 4A into the fitting recess 21f of the head body 21, fits the head side 2A of the joint body 5 into the fitting recess 21 into which the cylindrical portion 41c of this middle cannula 4A is inserted, and fits the tail side 2B of this joint body 5 into the fitting recess 22b of the tail body 22. As a result, the middle cannula 4A is configured to be fixed between the head body 21 and the tail body 22.

[0027] Furthermore, on the end face of the tail side 2b of the tail body 22, a mounting hole 22e having a circular cross section for fixing the sutte 4 is provided at a substantially central position of the end face of the tail side 2B of this tail body 22. This mounting hole 22e is provided along the side surface of the back side 2D of the tail body 22. Also, on the opening edge of the mounting hole 22e, a fixing step portion 22f for fitting and fixing the proximal end side of the sutte 4 is provided concentrically with this mounting hole 22e.

[0028] The sutures 4 attached to the tail side 2B (base end side) of the tail body 22 are fixed to an elongated columnar core material 42. In short, these sutures 4 are lower cannulas (intermediate umbrella-shaped needle bodies) 4B composed of a plurality of, for example, six needle materials 41. The needle tip portions 41a of these needle materials 41 are each projected in an umbrella shape in the radial direction, and the fixing portions 41b of these needle materials 41 are arranged in a circumferential shape to form a cylindrical tubular portion 41c. The core material 42 is inserted through this tubular portion 41c, and an elastic pipe body 43 is fitted and fixed to the outside of this tubular portion 41c to be configured as a two-stage cannula 8.

[0029] Specifically, as shown in FIGS. 1 to 5, this two-stage cannula 8 is a two-stage type in which a plurality of, for example, two lower cannulas 4B are continuously inserted through the tail side 2B of the core material 42. The core material 42 has an end portion protruding toward the head side 2A from the lower cannula 4B on the head side 2A of the core material 42, which is inserted into the mounting hole 22e of the tail body 22, and the tubular portion 41c of the lower cannula 4B on the head side 2A is fitted into the fixing step portion 22f of the tail body 22 and adhesively fixed to the tail side 2B of the tail body 22.

[0030] Furthermore, a cloth material (sheet body) 3 is affixed and fixed to each of the outer peripheral surface of the body portion 21b of the head body 21 and the outer peripheral surface of the tail body 22. As shown in FIGS. 1, 3, and 4, in the head body 21, the cloth material 3 is affixed from the back side 2D of the body portion 21b, and both edge portions of this cloth material 3 are pushed into the mounting groove portion 21e of the body portion 21b and adhesively fixed. Also, the cloth material 3 is attached so as to cover the locking groove portion 21d of the head body 21. The edge portion of the cloth material 3 covering this locking groove portion 21d is fixed by a string material 7 attached along this locking groove portion 21d, and the end portion of this string material 7 is also pushed into the mounting groove portion 21e and fixed. In the tail body 22, the cloth material 3 is affixed from the back side 2D of this tail body 22, and both edge portions of this cloth material 3 are pushed into the mounting groove portion 22a of the tail body 22 and adhesively fixed.

[0031] <Assembly Method> Next, a method (assembly process) for assembling the metal stud 1 according to the above-described embodiment will be described with reference to the drawings.

[0032] First, as shown in FIG. 2, prepare a pair of eye seals 24, a head body 21 to which a line eye 23 is attached, a total of eight needle members 41, a joint body 5, a two-stage cannula 8, a cloth material 3, and a string material 7.

[0033] Then, as shown in FIGS. 1, 3, and 4, attach the cloth material 3 from the back side 2D of the body portion 21b of the head body 21, and push both edge portions of the cloth material 3 into the attachment groove portion 21e of the body portion 21b to be adhesively fixed. Also, attach the string material 7 along the edge portion of the cloth material 3 covering the locking groove portion 21d of the head body 21 and press it down, and push both end portions of the string material 7 into the binding attachment groove portion 21e to be adhesively fixed. Thereafter, attach an eye seal 24 to each of the pair of eye fixing portions 21c of the head body 22. Also, attach the cloth material 3 from the back side 2D of the tail body 22, and push both edge portions of the cloth material 3 into the attachment groove portion 22a of the tail body 22 to be adhesively fixed.

[0034] Next, as shown in FIG. 2, project the needle tip portions 41a of each of the eight needle members 41 in an umbrella shape with the tip portions directed radially, form a cylindrical cylindrical portion 41c with the fixing portions 41b of each of these needle members 41 arranged circumferentially, and insert the cylindrical portion 41c in this state into each cannula fixing groove 21h of the head body 21.

[0035] In this state, apply a liquid adhesive G to the outer peripheral surface and end surface of the head side 2A of the joint body 5, and then fit and adhesively fix the head side 2A of the joint body 5 into the fitting concave portion 21f of the head body 21. At this time, a part of the adhesive G flows into and accumulates in the adhesive groove portion 5a on the head side 2A of the joint body 5, and the adhesive G flows into the gaps between the fixing portions 41b of each of the needle members 41, so that these needle members 41, the head body 21, and the joint body 5 are firmly adhesively fixed. As a result, the middle cannula 4A is firmly fixed to the tail side 2B of the head body 21 by the pressing by the joint body 5 and the adhesive fixing by the adhesive G.

[0036] Next, after applying a liquid adhesive G to each of the outer peripheral surface and the end surface of the tail side 2B of the joint body 5, as shown in FIG. 3, the tail side 2B of the joint body 5 is fitted into the fitting concave portion 22b of the tail body 22 until the fitting convex portion 5b of the tail side 2B of the joint body 5 fits into the fitting step portion 22d of the tail body 22. At this time, a part of the adhesive G accumulates in the adhesive groove portion 5b of the tail side 2B of the joint body 5, and the tail body 22 and the joint body 5 are firmly adhesively fixed by the fitting of the fitting convex portion 5b of the tail side 2B of the joint body 5 to the fitting step portion 22d of the tail body 22.

[0037] Here, a predetermined gap B is formed between the head body 21 and the tail body 22 connected via the joint body 5 such that each of the needle-like portions 41a of the middle-stage cannula 4A protrudes in an umbrella shape outside (in the radial direction) of the outer peripheral surfaces of the head body 21 and the tail body 22. In short, the joint body 5 has an exposed portion 5d that is not fitted to either the head body 21 or the tail body 22, and this exposed portion 5d is attached so as to be exposed from between the tail side 2b of the head body 21 and the head side 2A of the tail body 22. Then, the exposed portion 5d and the gap B are designed such that the exposed portion 5d and the gap B become smaller in accordance with the inclination angle of each needle-like portion 41a of the middle-stage cannula 4A. In short, the exposed portion 5d and the gap B are set to the minimum length dimension that allows each needle-like portion 41a of the middle-stage cannula 4A to protrude in an umbrella shape by inclining the needle-like portions 41a of the middle-stage cannula 4A toward the head side 2A from between the head body 21 and the tail body 22.

[0038] Furthermore, after applying a liquid adhesive G to the outer peripheral surface of the core material 42 protruding toward the head side 2A from the lower-stage cannula 4B on the upper stage of the two-stage cannula 8, the head side 2A of the core material 42 is inserted into the mounting hole 22e of the tail body 22 and adhesively fixed until the cylindrical portion 41c of the lower-stage cannula 4B on the upper stage fits into the fixing step portion 22f of the tail body 22 to form the metal stud 1.

[0039] <Usage method, etc.> Next, a method of using the metal swivel 1 according to the above-described embodiment, and its features and the like will be described with reference to the drawings.

[0040] First, as shown in FIG. 7, an edas (fishing line) L2 such as a fluorocarbon line is bound to a predetermined intermediate position of a trunk line (fishing line) L1 such as a fluorocarbon line cut to a predetermined length. Next, a snap S1 is connected to the tip of this edas L2, and a snap swivel S2 or the like is bound to the lower end of the trunk line L1. Also, if necessary, a swivel S3 or the like such as a swivel is bound to the upper end of the trunk line L1.

[0041] Next, a main line (fishing line) L such as a PE line is pulled out from the spool of a reel set on a rod (fishing rod), and the tip side of the main line L is sequentially inserted through each guide of this rod. Then, the tip of the main line L pulled out from the top guide of this rod is bound to the swivel S3. Then, the line eye 23 of the metal swivel 1 is connected to the snap swivel S2 bound to the lower end of the trunk line L1, and a dropper (bait tree, swivel, etc.) D is connected to the snap S1 bound to the tip of the edas L2.

[0042] Then, from a boat or the like, the clutch of the reel is disengaged (pushed) or the like so that the main line L can be freely released from the spool of this reel, and the metal swivel 1 and the dropper D are thrown into the sea. At this time, the tail body 22 of the metal swivel 1 gradually decreases in diameter from the head side 2A toward the tail side 2B, and the belly side 2C of the tail body 22 is inclined at a larger inclination angle than the back side 2D. For this reason, the head side 2A of the metal swivel 1 falls (sinks) downward powerfully with the head side 2A facing straight down.

[0043] After that, when the metal swivel 1 reaches a predetermined shelf (water depth), operations such as rotating the handle of the reel in the winding direction or returning the clutch are performed to make the main line L windable by this reel.

[0044] After that, the handle of the reel is rotated to wind up (reel in) the fishing line L, or the tip of the rod is moved up and down (rod action), etc., to move the metal jig 1 or the dropper D in the sea and lure the target squid in the sea.

[0045] Then, when the target squid hugs or bites the metal jig 1 with its tentacles and feels a strike, hooking is performed by lifting the rod or reeling in the reel, etc., and either the middle canna 4A or the lower canna 4B of this metal jig 1 is hooked (hit) on the tentacles, head, body, etc. of the squid.

[0046] At this time, the target squid aims at the position of the middle canna 4A attached between the body part of the jig body 2 of the metal jig 1, that is, between the head body 21 and the tail body 22, and hugs or bites with its tentacles. Therefore, by performing hooking instantaneously without delay at the timing of the strike of the squid, the squid can be hooked on the middle canna 4A of the metal jig 1 with a high probability.

[0047] Then, the handle of the reel is rotated to wind up and recover the fishing line L, and the hit squid is brought closer to the boat (taken in). After that, the rod and the reel are appropriately operated, and the hit squid is lifted onto the boat using a fishing net, gaff, etc., to catch it.

[0048] <Advantages and effects> As described above, the metal jig 1 according to the above embodiment is a center canna system in which the middle canna 4A is attached to the body part of the jig body 2, that is, between the head body 21 and the tail body 22. For this reason, generally when a squid preys on small fish, etc., it has a strong tendency to stretch out its tentacles and hug or bite the abdomen, which is the vulnerable part of the small fish. Therefore, the squid that hits the metal jig 1 often stretches out its tentacles and hugs or bites (hugs horizontally) the abdominal part of this metal jig 1, that is, the part where the middle canna 4A is attached.

[0049] Therefore, by performing the hooking operation immediately without hesitation at the moment when the squid is sensed, it is possible to highly probably hook the squid on the middle cutter 4A of the metal stake 1. Thus, by using the metal stake 1 for squid fishing (metal squid fishing), it is possible to perform (attack) squid fishing quickly and smoothly, so an increase in the fishing result can be expected.

[0050] In addition, a two-stage cutter 8 is attached to the tail side 2B of the metal stake 1. For this reason, when the squid is hooked on the middle cutter 4A of the metal stake 1 and the fishing line L is wound up and the boat is approached, it is highly likely that the hooked squid will also be hooked on any of the lower cutters 4B of the two-stage cutter 8 on the tail side 2B. Therefore, since the squid hooked on the metal stake 1 can be taken in (caught) with high probability (certainty), an increase in the fishing result can be expected by using this metal stake 1.

[0051] Furthermore, a cutter fixing groove 21h for fitting the fixing portion 41b of the needle material 41 is provided on the inner circumference of the fitting recess 21f of the head body 21 of the metal stake 1. For this reason, while fitting the fixing portion 41b of each needle material 41 into each of the cutter fixing grooves 21h, by fitting the head side 2A of the joint body 5 into the fitting recess 21f of the head body 21, the fixing portion 41b of each needle material 41 can be sandwiched and fixed between the inner circumferential surface of the fitting recess 21f of the head body 21 and the outer circumferential surface of the head side 2A of the joint body 5. Therefore, the fixing of a plurality of needle materials 41 to the head body 21 can be made accurate and firm, and displacement or removal of the needle-shaped portion 41a of the middle cutter 4A can be reliably prevented when using the metal stake 1 for squid fishing.

[0052] Further, the fitting recess 21f of the head body 21 and the fitting recess 22b of the tail body 22 of the metal stud 1 are each formed in a cross-sectional octagonal shape, and the joint body 5 to be fitted into these fitting recesses 21f and 22b is formed as a rod-shaped body with a cross-sectional octagonal shape. As a result, by fitting the joint body 5 into the fitting recesses 21f and 22b of the head body 21 and the tail body 22, the circumferential movement (displacement) of the joint body 5 with respect to these head body 21 and tail body 22 can be fixed. Therefore, alignment during assembly via the joint body 5 between the head body 21 and the tail body 22 can be easily performed, and rotation (displacement) of the tail body 22 in the circumferential direction with respect to the head body 21 can be prevented, so that the assembly process of the metal stud 1 can be simplified and the durability of the metal stud 1 can be improved.

[0053] Furthermore, mounting groove portions 21e and 22a are provided on the body portion 21b of the head 21 of the metal stud 1 and on the berry side 2C of each of the tail bodies 22, respectively, and the ends of the cloth material 3 covering the outer circumferences of the body portion 21b of the head body 21 and the tail body 22 are respectively pushed into the mounting groove portions 21e and 22a and adhesively fixed. For this reason, without overlapping the ends of the cloth material 3 to be attached to the body portion 21b of the head body 21 and the tail body 22, etc., the ends of each cloth material 3 can be pushed into the mounting groove portions 21e and 22a and hidden and adhesively fixed, so that the appearance of the metal stud 1 can be improved and peeling of the cloth material 3 during use can be appropriately prevented.

[0054] Also, the cloth material 3 covering the body portion 21b of the head body 21 of the metal stud 1 is attached so as to cover up to the locking groove portion 21d of the head body 21, and a string material 7 is attached along the locking groove portion 21d and tied and adhesively fixed to the edge portion of the cloth material 3 covering the locking groove portion 21d. As a result, the end portion on the head side 2A of the cloth material 3 covering the body portion 21b of the head body 21 can be fixed by the string material 7, and the string material 7 can be accommodated along the locking groove portion 21d of the head body 21. Therefore, at the time of falling, luring, or recovering of the metal stud 1, the portion that receives the most water pressure, that is, the end portion on the head side 2A of the cloth material 3 can be appropriately and firmly fixed, so that peeling of the cloth material 3 attached to the body portion 21b of the head body 21 during use can be prevented.

[0055] As described above, the metal jig 1 according to the present invention contributes to the solution of goals such as Goal 12: Responsibility to produce and use, and Goal 14: Protect the richness of the sea, which are the goals of the SDGs.

[0056] (Others) Note that the present invention is not limited to the above-described embodiments, and various modifications are included. For example, the above-described embodiments are described for the purpose of explaining the present invention in an easy-to-understand manner, and the present invention is not necessarily limited to those having all the configurations described.

[0057] In particular, in the above embodiment, the metal jig 1 in which each of the squid body 2 and the joint body 5 is made of a metal material having a relatively large specific gravity such as lead. However, for example, by configuring each of the head body 21 and the tail body 22 of the squid body 2 and the joint body 5 with a hollow resin material or wood having a small specific gravity to have buoyancy, it can be used not as a lead jig for squid metal but as a mimic bait for squid fishing that can be used as a dropper D connected to the edas L2.
