Description

  The present invention relates to a lure used for fishing. More particularly, the present invention relates to a gravity center moving lure.

  Large fish such as largemouth bass, yellowtail and their juveniles, sea bass, etc. feed on small fish as baits. These large fish are called fish eaters. Lure fishing is widely used as a means of capturing fish eaters. In lure fishing, lures are used. A line is connected to the lure. The lure flies through the air by casting, and eventually reaches the water. The lure swims underwater as the line is wound. The fish eater who misunderstood this lure as bait bites the lure. The hook attached to the lure pierces the fish eater and the fish eater is picked up.

  An angler may want to cast a lure far away. As mentioned above, lures fly in the air. During flight, the lure receives air resistance. Lures with low air resistance can be cast far away.

  As mentioned above, the fish eater bites into this lure by mistaking it as bait. A lure that achieves an underwater posture and action that invites misunderstanding of the fish eater is preferred.

  Japanese Patent Laid-Open No. 2007-209229 discloses a gravity center moving lure. In this lure, the weight built in the body can move in the front-rear direction. When flying in the air, the weight is located on the rear side (that is, the tail side). In other words, the center of gravity of the lure during flight is closer to the tail. This lure flies with the tail at the head. Since the air resistance in this flight position is small, the lure can be cast away. After landing, the weight moves to the front side (that is, the head side). Underwater, the weight is held on the head side. In other words, the center of gravity of the lure in water is closer to the head. The position of the center of gravity contributes to the lure's underwater posture and action. In this lure, a magnet is used as means for holding the weight on the head side. A lure in which a weight is held on the head side by a step is also commercially available.

JP 2007-209229 A

  In the lure disclosed in the above publication, a chamber for moving the weight needs to be formed inside the body. Furthermore, this lure requires a space for mounting a magnet. Even in the case of a lure that holds a weight by a step instead of a magnet, the step needs to be formed in the chamber. Conventional lures that are center-of-gravity are generally complex in structure.

  An object of the present invention is to provide a center-of-gravity movement type lure having a simple structure.

  The lure according to the present invention includes a body having a head and a tail, a guide wire built in the body, a weight built in the body and movable back and forth along the guide wire, and built in the body. Locking means. When the weight is located in front of the locking means in the water, the locking means prevents the weight from moving backward and achieves a center of gravity closer to the head. The rear center of gravity achieves a center of gravity close to the tail.

  According to another aspect, the lure according to the present invention includes a body having a head and a tail, a guide wire incorporated in the body, and a weight that is incorporated in the body and can move back and forth along the guide wire. A weight. This guide wire has a flat portion extending in the front-rear direction and a locking means positioned on the front side of the flat portion. When the weight is located in front of the locking means in the water, the locking means prevents the weight from moving rearward and achieves a center of gravity closer to the head. The center of gravity close to the tail is achieved by positioning the weight behind the locking means during casting.

  The guide wire may have a step. This level difference functions as locking means.

  Preferably, the weight includes a wheel shaft and a pair of left and right wheels having a size larger than the diameter of the wheel shaft. When the wheel shaft is sandwiched between the two wheels, an annular groove is formed between the wheels. When the guide wire is fitted into the annular groove, the weight can be moved by being guided by the guide wire.

  Preferably, the lure further includes a restriction wire built in the body and positioned above the guide wire. By restricting the upward movement of the weight by the restriction wire, derailment of the weight from the guide wire is prevented.

  Preferably, the guide wire is movable in the front-rear direction with respect to the body. When the guide wire is in the front position, the guide wire is pivotable with respect to the body. When the guide wire is in the rear position, the guide wire is prevented from rotating relative to the body.

  The body may include a front plate and a rear plate. The guide wire is passed through the front plate and the rear plate. Preferably, the front plate has a recess on its front surface, and the guide wire has a bent portion at its front end. When the bent portion is fitted in the recess, the guide wire is prevented from rotating with respect to the body.

  Preferably, the guide wire includes a large-diameter portion positioned in front of the step portion. The weight is cylindrical and has an inner surface having a hole and a slit continuous with the hole. The rear end surface of the weight is inclined with respect to the axial direction. By this inclination, a long side and a short side are formed on this weight. The hole is eccentric to the long side with respect to the center of the outer peripheral surface of the weight. The slit extends from the hole toward the short side. The inner diameter of the hole is larger than the diameter of the thick part. The width of the slit is smaller than the diameter of the large diameter portion and larger than the diameter of the step portion.

  The guide wire may include an inclined portion. The inclined portion is located on the front side of the flat portion and has a smaller diameter than the flat portion. The guide wire can be bent near the boundary between the upper carrier part and the inclined part. Due to this bending, the inclined portion inclines from the belly toward the back as it goes forward. A bent portion formed in the vicinity of this boundary can function as a locking means.

  In the lure according to the present invention, a proper posture and action in water and a large flight distance at the time of casting are compatible by moving the weight. The structure of this lure is simple.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  The lure 2 shown in FIGS. 1 to 3 includes a body 4, a line eye 6, three hook eyes 8, a guide wire 10, a restriction wire 12, and a weight 14. Also shown in FIG. 1 are line 16 and three hooks 18.

  The body 4 has an outline similar to a small fish that is a bait. Typically, the body 4 is made of a synthetic resin. A preferred synthetic resin is an ABS resin. The body 4 may be made of a metal material or a wood material. The body 4 is hollow. The body 4 includes a main frame 20, a front plate 22 and a rear plate 24. The main frame 20, the front plate 22, and the rear plate 24 are integrally formed. The main frame 20 has a head 26 and a tail 28.

  The line eye 6 and the hook eye 8 are formed by bending a metal wire. A typical material for the metal wire is stainless steel. A part of the metal wire is embedded in the body 4, and the remaining part is exposed from the body 4. The line eye 6 and the hook eye 8 are fixed to the body 4 by being embedded. As shown in FIG. 1, a line 16 is connected to the line eye 6. The line 16 may be connected to the line eye 6 via a split ring. A hook 18 is attached to the hook eye 8 via a split ring 30.

  As shown in FIG. 2, the guide wire 10 is built in the body 4. The guide wire 10 generally extends in the front-rear direction. The guide wire 10 includes a flat part 32, a step part 34, a receiving part 36, a front step part 38, and a front flat part 40. The front end of the front flat portion 40 is fixed to the front plate 22. The rear end of the flat portion 32 is fixed to the rear plate 24. The step portion 34 is continuous with the flat portion 32 and is located on the front side of the flat portion 32. The receiving portion 36 is continuous with the step portion 34 and is located below the flat portion 32. The guide wire 10 is made of a metal wire. Typical materials for the guide wire 10 include steel, stainless steel, copper alloy, and titanium alloy. Surface treatment may be applied to the surface of the metal wire for the purpose of reducing frictional force.

  The restriction wire 12 is built in the body 4. The restriction wire 12 is straight and extends in the front-rear direction. The restriction wire 12 is substantially parallel to the flat portion 32. The front end of the restriction wire 12 is fixed to the front plate 22. The rear end of the restriction wire 12 is fixed to the rear plate 24. The material of the restriction wire 12 is the same as the material of the guide wire 10.

  The weight 14 is built in the body 4. As shown in FIG. 3, the weight 14 includes a wheel shaft 42 and a pair of left and right wheels 44. The wheel shaft 42 and the wheel 44 are integrally formed. Each wheel 44 has a size larger than the diameter of the wheel shaft 42. An annular groove 46 is formed between the wheels 44 by sandwiching the wheel shaft 42 between the two wheels 44. The specific gravity of the weight 14 is larger than the specific gravity of the body 4. Examples of the material of the weight 14 include lead, a lead alloy, brass, tungsten, a tungsten alloy, steel, and stainless steel.

  In the state shown in FIG. 3, the guide wire 10 and the regulation wire 12 are fitted in the annular groove 46. The guide wire 10 is positioned below the wheel shaft 42 and is in contact with the wheel shaft 42. The restriction wire 12 is located above the wheel shaft 42 and is separated from the wheel shaft 42. The weight 14 can move along the guide wire 10 when the wheel shaft 42 rotates on the guide wire 10 or when the wheel shaft 42 slides relative to the guide wire 10. The weight 14 can move forward and backward. As described above, since the guide wire 10 is fitted in the annular groove 46, the weight 14 moves while being guided by the guide wire 10.

  When the weight 14 moves upward in FIG. 3, the restriction wire 12 comes into contact with the wheel shaft 42. Due to this contact, further upward movement of the weight 14 is restricted. Therefore, the state in which the guide wire 10 is fitted in the annular groove 46 is maintained. In other words, the restriction wire 12 prevents the weight 14 from derailing from the guide wire 10.

  4 and 5 show part of the lure 2. In FIG. 4, the weight 14 is located in front of the step portion 34. The wheel shaft 42 is on the receiving portion 36. In FIG. 5, the weight 14 is located behind the stepped portion 34. The weight 14 is located near the rear plate 24. The wheel shaft 42 is on the flat portion 32.

  The cast lure 2 flies and lands. As the line 16 is drawn, the lure 2 travels underwater. At this time, since the head 26 receives water pressure, the lure 2 swims with the head 26 below the tail 28 as shown in FIG. Accordingly, the guide wire 10 is forwardly lowered. The weight 14 moves forward while being guided by the guide wire 10. By this movement, the weight 14 passes through the step portion 34. The weight 14 is placed in the position shown in FIG. In the state shown in FIG. 4, the center of gravity near the head 26 is achieved. The position of the center of gravity is an appropriate position for the lure 2 in water. The lure 2 having an appropriate center of gravity position maintains an appropriate posture in water. When the lure 2 having the proper center of gravity is drawn on the line 16, the lure 2 takes a good action. This lure 2 will appeal to the fish eater.

  In the water, the lure 2 may temporarily take a horizontal posture or a slightly upward posture. Even in this case, the step portion 34 prevents the weight 14 from moving backward. In this lure 2, an appropriate center of gravity is maintained.

  When the retrieval is finished, the angler raises the rod and picks up the lure 2 from the water. Since the line 16 is connected to the line eye 6 and this line eye 6 is located at the front end of the body 4, the lure 2 stands as shown in FIG. Furthermore, the lure 2 vibrates by pinking up. Due to the standing and vibration, the wheel shaft 42 gets over the stepped portion 34 and the weight 14 moves toward the tail 28. This movement is made along the guide wire 10. The weight 14 is placed in the position shown in FIG. In the state shown in FIG. 5, the center of gravity close to the tail 28 is achieved. When the lure 2 is cast, the lure 2 flies while keeping the weight 14 at a position near the tail 28 due to centrifugal force and inertia. The lure 2 flies in a posture with the tail 28 at the head. The air resistance at this time is small. With this lure 2, a great flight distance can be obtained.

  In this lure 2, it is not necessary to provide a chamber for the weight 14 to move. There is no need to provide a step in the chamber to maintain the weight 14 at a predetermined position. Further, it is not necessary to provide a magnet for maintaining the weight 14 in a predetermined position. The lure 2 can be easily manufactured.

  In the lure 2, the size of the stepped portion 34 is determined so that the wheel shaft 42 can be prevented from getting over in water. Since the wheel shaft 42 has a smaller diameter than the wheel 44, it can be prevented from getting over by the relatively small step 34. The small step portion 34 can also be formed on the lure 2 where the body 4 has a small height. On the other hand, since the wheel 44 has a large diameter, the center of gravity moves greatly. The weight 14 including the wheel shaft 42 and the wheel 44 can achieve a center-of-gravity movement distance that cannot be achieved by a conventional lure.

  In FIG. 3, the diameter of the wheel 44 is indicated by the arrow D1, and the diameter of the wheel shaft 42 is indicated by the arrow D2. The ratio (D1 / D2) is preferably (1.5 / 1.0) or more from the viewpoint that easy formation of the stepped portion 34 and a large center-of-gravity movement distance are achieved, and (2.0 / 1 0.0) or more is particularly preferable.

  FIG. 6 shows a lure 50 according to another embodiment of the present invention. FIG. 6 shows the body 4, the guide wire 10, the two restriction wires 52, and the weight 14. The components of the luer 50 other than the restriction wire 52 are the same as those of the luer 2 shown in FIGS.

  Each regulation wire 52 is located above the wheel shaft 42 and is close to the wheel 44. The restriction wire 52 is not fitted in the annular groove 46. The restriction wire 52 also restricts the upward movement of the weight 14. The restriction wire 52 prevents derailment of the weight 14 from the guide wire 10.

  In this lure 50, it is not necessary to provide a chamber for moving the weight 14. There is no need to provide a step in the chamber to maintain the weight 14 at a predetermined position. Further, it is not necessary to provide a magnet for maintaining the weight 14 in a predetermined position. The lure 50 can be easily manufactured. In this lure 50, the relatively small step 34 can prevent the wheel shaft 42 from getting over.

  7 and 8 show a luer 56 according to yet another embodiment of the present invention. The lure 56 includes a body 58, a line eye 6, three hook eyes 8, a guide wire 60, a restriction wire 12, and a weight 14. The body 58 includes a main frame 18, a front plate 62, and a rear plate 64. The components of the luer 56 other than the guide wire 60, the front plate 62, and the rear plate 64 are the same as those of the lure 2 shown in FIGS.

  As shown in FIG. 7, the guide wire 60 includes a back bent portion 66, a flat portion 68, a stepped portion 70, a receiving portion 72, a front stepped portion 74, a front flat portion 76, and a front bent portion 78. The rear bent portion 66 is suspended from the flat portion 68. The step portion 70 is continuous with the flat portion 68 and is located on the front side of the flat portion 68. The receiving portion 72 is continuous with the stepped portion 70 and is located below the flat portion 68. The front bent portion 78 is suspended from the front flat portion 76.

  FIG. 8 shows the front plate 62 and the guide wire 60. The front plate 62 includes a bearing hole 80 and a recess 82. The front flat portion 76 of the guide wire 60 is passed through the bearing hole 80. The inner diameter of the bearing hole 80 is slightly larger than the diameter of the guide wire 60. The guide wire 60 can rotate with respect to the front plate 62 and can be slid in the front-rear direction with respect to the front plate 62. The front bent portion 78 prevents the guide wire 60 from dropping from the front plate 62. The recess 82 includes a groove 84 and two slope surfaces 86. The groove 84 is continuous with the bearing hole 80. The width W1 of the groove 84 (see FIG. 8C) is substantially the same as the inner diameter of the bearing hole 80. Each slope surface 86 extends from the front surface 88 of the front plate 62 to the groove 84. The distance between the two slope surfaces 86 gradually decreases from the front surface 88 toward the groove 84.

  Although not shown, the rear plate 64 also has a bearing hole. The flat portion 68 of the guide wire 60 is passed through the bearing hole. The inner diameter of the bearing hole is slightly larger than the diameter of the guide wire 60. The guide wire 60 can rotate with respect to the rear plate 64 and can be slid in the front-rear direction with respect to the rear plate 64. The rear bent portion 66 prevents the guide wire 60 from falling off the rear plate 64.

  9 and 10, a portion of the luer 56 is shown. In FIG. 9, the weight 14 is located in front of the stepped portion 70. The wheel shaft 42 is on the receiving portion 72. The restriction wire 12 is detached from the annular groove 46 (see FIG. 11). The guide wire 60 is in the forward position. Accordingly, the front bent portion 78 is separated from the front plate 62, and the rear bent portion 66 is in contact with the rear surface 90 of the rear plate 64.

  In FIG. 10, the weight 14 is located behind the stepped portion 70. The weight 14 is located near the rear plate 64. The wheel shaft 42 is on the flat portion 68. The restriction wire 12 is fitted in the annular groove 46 (see FIG. 11). The guide wire 60 is in the rear position. Therefore, the front bent portion 78 (see FIG. 9) is in contact with the front plate 62, and the rear bent portion 66 is separated from the rear plate 64.

  The cast lure 56 flies and lands. As the line 16 is drawn, the lure 56 travels underwater. At this time, since the head 26 receives water pressure, the lure 56 swims with the head 26 below the tail 28 as shown in FIG. Therefore, the guide wire 60 is forwardly lowered. The weight 14 moves forward while being guided by the guide wire 60. Due to this movement, the weight 14 passes through the stepped portion 70. The guide wire 60 moves forward due to its own weight and the mass of the weight 14. The weight 14 and the guide wire 60 are accommodated in the positions shown in FIG. The center of gravity is closer to the head 26. In this state, the lure 56 maintains an appropriate posture in water. This lure 56 causes good action.

  When the retrieval is finished, the angler raises the rod and picks up the lure 56 from the water. The luer 56 stands as shown in FIG. The guide wire 60 moves backward due to its own weight and the mass of the weight 14. Further, the wheel shaft 42 gets over the stepped portion 70, and the weight 14 moves toward the tail 28. The weight 14 and the guide wire 60 are accommodated at the positions shown in FIG. The center of gravity is closer to the tail 28. When the lure 56 is cast, the lure 56 flies while keeping the weight 14 at a position near the tail 28. The lure 56 flies in a posture with the tail 28 at the head. The air resistance at this time is small. With this lure 56, a large flight distance can be obtained.

FIG. 11 shows the luer 56 when the guide wire 60 is in the forward position. In FIG. 11A, the center line CL1 of the body 58 extends in the vertical direction. In FIG. 11B, the center line CL1 of the body 58 is inclined to the right with respect to the vertical direction. In FIG. 11C, the center line CL1 of the body 58 is inclined to the left with respect to the vertical direction. When the body 58 rolls clockwise, the state shown in FIG. 11A shifts to the state shown in FIG. When the body 58 rolls counterclockwise, the state shown in FIG. 11A shifts to the state shown in FIG. When swimming underwater, the body 58
(1) Transition from the state shown in FIG. 11 (a) to the state shown in FIG. 11 (b) (clockwise rolling)
(2) Transition from the state shown in FIG. 11B to the state shown in FIG. 11A (counterclockwise rolling)
(3) Transition from the state shown in FIG. 11 (a) to the state shown in FIG. 11 (c) (counterclockwise rolling)
And (4) transition from the state shown in FIG. 11 (c) to the state shown in FIG. 11 (a) (clockwise rolling)
repeat.

  As shown in FIGS. 11A to 11C, the center line CL2 of the weight 14 extends substantially in the vertical direction. In other words, even when the body 58 rolls, the weight 14 hardly rolls. The reason is that the guide wire 60 can rotate with respect to the front plate 62 and the rear plate 64, the restriction wire 12 is removed from the annular groove 46, and inertia acts on the weight 14. When the weight 14 is at the position shown in FIG. 9, the stepped portion 70, the receiving portion 72, and the front stepped portion 74 are fitted in the annular groove 46. Therefore, the weight 14 and the guide wire 60 are integrally rotated relative to the body 58 and do not roll in the vertical direction. In FIG. 8A, a guide wire 60 (forward bent portion 78) that rotates relative to the body 58 is indicated by a two-dot chain line.

  With conventional lures, the weight rolls as the body rolls. The weight generates a moment in a direction that inhibits rolling of the body. In the present invention, since the weight 14 does not roll, the generated moment is small. The weight 14 is unlikely to hinder rolling of the body 58. The lure 56 swings sufficiently in water. This swing appeals to the fish eater.

  FIG. 12 shows the guide wire 60 and the front plate 62. In FIG. 12, the guide wire 60 is in the rear position. As described above, when the guide wire 60 is in the forward position, the front bent portion 78 rotates relative to the body 58. When the guide wire 60 moves from the front position to the rear position, the front bent portion 78 fits into the groove 84 while being guided by the slope surface 86. When guided by the slope surface 86, the rotation width of the guide wire 60 gradually decreases. When the forward bent portion 78 is fitted into the groove 84, the groove 84 prevents the guide wire 60 from rotating. Therefore, the rotation of the weight 14 with respect to the body 58 is also prevented. The weight 14 and the restriction wire 12 maintain the positional relationship shown in FIG. Since the weight 14 moves rearward in this state, the control wire 12 is fitted into the annular groove 46 when the step is overcome, and derailment of the weight 14 is prevented. In other words, the dent 82 serves to prevent derailment when the weight 14 starts moving backward.

  The luer 56 does not require a chamber for moving the weight 14. There is no need to provide a step in the chamber to maintain the weight 14 at a predetermined position. Further, it is not necessary to provide a magnet for maintaining the weight 14 in a predetermined position. The lure 56 can be easily manufactured. In the lure 56, the relatively small stepped portion 70 can prevent the wheel shaft 42 from getting over.

  13 and 14 show a luer 94 according to yet another embodiment of the present invention. The lure 94 includes a body 4, a line eye 6, three hook eyes 8, a guide wire 96, a restriction wire 12, and a weight 98. The components of the luer 94 other than the guide wire 96 and the weight 98 are the same as those of the luer 2 shown in FIGS.

  As shown in FIG. 13, the guide wire 96 has a flat part 100, a step part 102, and a receiving part 104. The front end of the receiving portion 104 is fixed to the front plate 22. The rear end of the flat part 100 is fixed to the rear plate 24. The step portion 102 is continuous with the flat portion 100 and is located on the front side of the flat portion 100. The receiving portion 104 is continuous with the step portion 102 and is located below the flat portion 100. The receiving portion 104 includes a large diameter portion 106.

  The weight 98 is cylindrical. The rear end surface 108 of the weight 98 is inclined with respect to the axial direction. Due to this inclination, a long side 110 and a short side 112 are formed on the weight 98. In FIG. 13, the long side 110 is located below the short side 112.

  As shown in FIG. 14, the inner surface of the weight 98 includes a hole 114 and a slit 116. The hole 114 penetrates from the front end surface 118 to the rear end surface 108. The slit 116 also penetrates from the front end surface 118 to the rear end surface 108. The center of the hole 114 is located below the center of the weight 98 in FIG. In other words, the hole 114 is eccentric to the long side 110 with respect to the center of the outer peripheral surface of the weight 98. The slit 116 extends from the hole 114 toward the short side 112. The inner diameter D3 of the hole 114 is larger than the diameter of the large diameter portion 106. The width W2 of the slit 116 is smaller than the diameter of the large diameter portion 106 and larger than the diameter of the stepped portion 102 (diameter of the guide wire 96).

  Even in this lure 94, the center of gravity fluctuates due to the movement of the weight 98 in the front-rear direction. 15 and 16 show the lure 94 in water. The lure 94 swims underwater with the head 26 positioned below the tail 28. The weight 98 is in front of the stepped portion 102. The large diameter portion 106 is passed through the hole 114. Since the hole 114 is eccentric to the long side 110, due to the dead weight of the weight 98, the long side 110 is located above and the short side 112 is located below. When the rear end surface 108 abuts on the stepped portion 102, the backward movement of the weight 98 is prevented. Since the weight 98 is in front of the step portion 102, the center of gravity is closer to the head 26. The lure 94 maintains a proper posture in the water. The lure 94 takes good action.

  When the lure 94 is picked up, the lure 94 rises as shown in FIGS. By erecting, first, the long side 110 of the rear end surface 108 contacts the stepped portion 102. The weight 98 rotates 180 ° in order to shift to a stable state in terms of potential energy. Therefore, as shown in FIG. 18, the long side 110 of the weight 98 is positioned below the short side 112. In this state, the slit 116 can pass through the step portion 102. 19 and 20 show a state in which the slit 116 is passing through the step portion 102. The weight 98 that has passed through the stepped portion 102 is positioned near the rear plate 24 as shown in FIG. When cast in this state, the lure 94 flies in a posture with the tail 28 at the head. The air resistance at this time is small. With this lure 94, a great flight distance can be obtained. After landing, the weight 98 moves forward. When moving, the slit 116 passes through the step portion 102, and the weight 98 is positioned in front of the step portion 102.

  In this lure 94, it is not necessary to provide a chamber for the weight 98 to move. The chamber need not be provided with a step for maintaining the weight 98 in a predetermined position. Further, it is not necessary to provide a magnet for maintaining the weight 98 in a predetermined position. The lure 94 can be easily manufactured.

  22 and 23 show a luer 122 according to yet another embodiment of the present invention. The lure 122 includes a body 4, a line eye 6, three hook eyes 8, a rail 124, a guide wire 126, and a weight 128. The components of the luer 122 other than the guide wire 126, the rail 124, and the weight 128 are the same as those of the lure 2 shown in FIGS.

  As shown in FIG. 23, a pair of rails 124 are arranged in parallel at a predetermined interval. Each rail 124 protrudes inward in the width direction from the inner peripheral surface of the body 4. The rail 124 is joined to the body 4. The rail 124 is on the back side with respect to the guide wire 126. As shown in FIG. 22, the rail 124 extends in the longitudinal direction.

  As shown in FIG. 22, the guide wire 126 has a flat part 130, an inclined part 132, and a bent part 134. The front end of the inclined portion 132 is fixed to the front plate 22. The inclined portion 132 rises forward. The rear end of the flat part 130 is fixed to the rear plate 24. The inclined portion 132 is continuous with the flat portion 130 and is located in front of the flat portion 130. The inclined portion 132 has a smaller diameter than the flat portion 130. Near the boundary between the flat part 130 and the inclined part 132 is a bent part 134.

  The weight 128 is cylindrical. The weight 128 includes a hole 136 (see FIG. 23). The hole 136 penetrates from the front end surface 138 (see FIG. 22) of the weight 128 to the rear end surface 140. The center of the hole 136 is located below the center of the weight 128 in FIG. In other words, the hole 136 is eccentric with respect to the center of the outer peripheral surface of the weight 128. The inner diameter of the hole 136 is slightly larger than the outer diameter of the flat portion 130.

  Even in this lure 122, the center of gravity fluctuates due to the movement of the weight 128 in the front-rear direction. 24 and 25 show the lure 122 in water. The lure 122 swims in the water with the head 26 positioned below the tail 28. As shown in FIG. 25, the weight 128 is in front of the bent portion 134. An inclined portion 132 is passed through the hole 136. When the weight 128 tries to move backward, the rear end surface 140 of the weight 128 comes into contact with the step 142 caused by the difference in diameter between the flat portion 130 and the inclined portion 132. Due to this contact, the backward movement of the weight 128 is prevented. Since the weight 128 is in front of the bent portion 134, the center of gravity is closer to the head 26. The lure 122 maintains a proper posture in water. The lure 122 takes good action.

  When the luer 122 is picked up, the luer 122 stands as shown in FIGS. The weight 128 rotates 180 ° in order to shift to a stable state in terms of potential energy. The weight 128 further moves to the right in FIG. In this state, the flat part 130 can enter the hole 136. The weight 128 falls by its own weight toward the tail 28. When falling, the rail 124 prevents the weight 128 from rotating. In other words, the weight 128 moves while being guided by the flat portion 130 and the rail 124. The weight 128 is located near the rear plate 24 as shown in FIG. When cast in this state, the lure 122 flies in a posture with the tail 28 at the top. The air resistance at this time is small. With this lure 122, a large flight distance can be obtained. After landing, the weight 128 moves forward. The weight 128 passes through the bent portion 134.

  In the luer 122, it is not necessary to provide a chamber for moving the weight 128. There is no need to provide a step in the chamber to maintain the weight 128 at a predetermined position. Furthermore, it is not necessary to provide a magnet for maintaining the weight 128 in a predetermined position. The lure 122 can be easily manufactured.

  29 and 30 show a luer 150 according to yet another embodiment of the present invention. The lure 150 includes a body 4, a line eye 6, three hook eyes 8, an upper rail 152, a lower rail 154, a guide wire 156, and a weight 158. The components of the luer 150 other than the guide wire 156, the upper rail 152, the lower rail 154, and the weight 158 are the same as those of the luer 2 shown in FIGS.

  As shown in FIG. 30, a pair of upper rails 152 are arranged in parallel at a predetermined interval. Each upper rail 152 protrudes inward in the width direction from the inner peripheral surface of the body 4. The upper rail 152 is joined to the body 4. As shown in FIG. 29, the upper rail 152 extends in the longitudinal direction.

  As shown in FIG. 30, a pair of lower rails 154 are arranged in parallel at a predetermined interval. Each lower rail 154 protrudes inward in the width direction from the inner peripheral surface of the body 4. The lower rail 154 is joined to the body 4. As shown in FIG. 29, the lower rail 154 extends in the longitudinal direction.

  As shown in FIG. 29, the guide wire 156 has a flat part 160, an inclined part 162, and a bent part 164. The front end of the inclined portion 162 is fixed to the front plate 22. The inclined portion 162 rises forward. The rear end of the flat part 160 is fixed to the rear plate 24. The inclined portion 162 is continuous with the flat portion 160 and is located in front of the flat portion 160. Near the boundary between the flat portion 160 and the inclined portion 162 is a bent portion 164.

  The weight 158 is cylindrical. The weight 158 includes a hole 166 (see FIG. 30). The hole 166 penetrates from the front end surface 168 (see FIG. 29) of the weight 158 to the rear end surface 170. The center of the hole 166 is located below the center of the weight 158 in FIG. In other words, the hole 166 is eccentric with respect to the center of the outer peripheral surface of the weight 158. The inner diameter of the hole 166 is slightly larger than the outer diameter of the guide wire 156.

  Even in this lure 150, the center of gravity fluctuates due to the movement of the weight 158 in the front-rear direction. FIG. 31 shows the lure 150 in water. The lure 150 swims in the water with the head 26 positioned below the tail 28. As shown in FIG. 31, the weight 158 is in front of the bent portion 164 (see FIG. 29). An inclined portion 162 is passed through the hole 166. The rear end surface 170 is in contact with the lower rail 154. Due to this contact, the backward movement of the weight 158 is prevented. The lower rail 154 functions as locking means. Since the weight 158 is in front of the bent portion 164, the center of gravity is closer to the head 26. The lure 150 maintains a proper posture in water. The lure 150 takes good action.

  When the lure 150 is picked up, the lure 150 stands up as shown in FIG. The weight 158 rotates 180 ° in order to shift to a stable state in terms of potential energy. In this state, the rear end surface 170 does not contact the lower rail 154. The weight 158 falls by its own weight toward the tail 28. When falling, the upper rail 152 prevents the weight 158 from rotating. In other words, the weight 158 moves while being guided by the flat portion 160 and the upper rail 152. The weight 158 is located near the rear plate 24 as shown in FIG. When cast in this state, the lure 150 flies in a posture with the tail 28 at the head. The air resistance at this time is small. With this lure 150, a large flight distance can be obtained. After landing, the weight 158 moves forward. The weight 158 passes through the bent portion 164.

  In this lure 150, it is not necessary to provide a chamber for the weight 158 to move. The chamber need not be provided with a step for maintaining the weight 158 at a predetermined position.
