Description

Artificial bait

Technical Field

The present invention relates to a lure for fishing (lure).

Background

The largesized fishes such as the Micropterus salmoides, the amber fishes, the juvenile fishes, the weever and the like prey on the small fishes. These large fish are called fish eaters (fish eaters). As a method for capturing fish-eating fish, a bait fishing method is widely used. In the bait-simulating fishing method, a bait of a fish bait such as a suspected small fish is used. The lure flies in the air by being thrown (cast), and soon falls into the water. The lure swims in the water by winding the fishing line. The artificial bait is mistaken for a fish-eating fish bite artificial bait. The fishhook attached to the lure is inserted into the fish-eating fish to thereby fish the fish-eating fish. The frequency of biting of the lure by the fish-eating fish is called the hook-up rate.

Various improvements have been made to the lure in order to increase the rate of hooking. For example, a coating with luster is applied to the lure. In the lure, when the lure is operated, the light reflection state is changed to attract fish-eating fish. Another type of lure has a Rattle ball (Rattle ball) in a space inside the body of the lure. When the lure is actuated, the ball rolls to make a sound to attract fish-eating fish. Also known is a lure which moves while vibrating when pulled. These kinds of baits have been disclosed by "2017 island fishing gear catalog" issued by seiko corporation.

Disclosure of Invention

[ technical problem to be solved by the invention ]

In the bait fishing method, after a fisher throws out the bait, the action of pulling a fishing line and the action of stopping the pulling are repeated. When pulling of the lure is stopped, the action of the lure is substantially stopped in a place where water does not substantially flow, such as a still water area, a sea area where ocean currents and ocean waves are small, and the like. In order to increase the rate of catching fish, it is desired to have a lure which can attract fish after the action of the lure is stopped.

The invention aims to provide a lure which can attract fish after the action of the lure is stopped.

The fishing line hole 6 and the fishhook hole 8 are firmly fixed to the lure body 4. A fishing line 28 is mounted on the fishing line hole 6. A hook 10 is attached to each hook hole 8. In this embodiment, the number of the hooks 10 is 2.

As shown in fig. 2, the rocking section 12 is located inside the main cavity 24. The plurality of rocking sections 12 are arranged in the front-rear direction. In this embodiment, three rocking sections 12, i.e., a first rocking section 12a, a second rocking section 12b, and a third rocking section 12c, are located in the main cavity 24. Each oscillating portion 12 has a plate shape. Fig. 3 shows an enlarged view of the vicinity of the second oscillating portion 12b in fig. 2. The rocking section 12 has a hole 30 penetrating in the thickness direction. In this embodiment, each rocking section 12 has two holes 30.

The oscillating portion 12 receives light from the outside and emits the light. In this embodiment, the oscillating portion 12 is a reflector. That is, the surface of the oscillating portion 12 reflects light. The surface of the rocking section 12 is glossy. The surface of the rocking section 12 may be colored or a pattern may be added. The oscillating portion 12 is typically formed of a synthetic resin composition. The rocking section 12 may be formed of metal. A hologram plate (holoplate) is exemplified as a typical oscillating portion 12. The oscillating portion 12 may be a phosphor.

As shown in fig. 3, the rocking section 12 has recesses 32 on its upper end side and lower end side. Notches 34 extending from the bottom of each recess 32 are provided in the rocking section 12. As shown in fig. 3, a first notch 34a extending from a front end of the bottom of the recess 32 and a second notch 34b extending from a rear end are provided. The portion divided by the first notch 34a and the second notch 34b is referred to as a fixing portion 36. The fixing portion 36 has a head portion 38 exposed to the bottom of the recess 32 and a neck portion 40 narrower in width than the head portion 38.

The elastomer 14 is located inside the main cavity 24. In this embodiment, the elastic body 14 is a spring 14. As shown in fig. 2, there are a first spring 14a located on the upper side of the rocking section 12 and a second spring 14b located on the lower side of the rocking section 12. In this embodiment, the number of the first springs 14a and the number of the second springs 14b are 3, respectively. The first spring 14a and the second spring 14b extend in the up-down direction, respectively.

As shown in fig. 2 and 3, the upper ends of the first springs 14a are respectively hooked on the hooking rods 26. The lower end of the first spring 14a is inserted into the notch 34 on the upper side. The lower end of the first spring 14a is hooked on the neck 40 of the fixing portion 36 on the upper side. The lower end of each second spring 14b is hooked on the hooking rod 26. The upper end of the second spring 14b is inserted into the notch 34 on the lower side. The upper end of the second spring 14b is hooked on the neck 40 of the lower fixing portion 36. The rocking section 12 is installed between the first spring 14a and the second spring 14 b. The rocking section 12 can vibrate with respect to the lure body 4 by these springs 14. The swinging portion 12 can swing back and forth, up and down, and right and left by the spring 14. The rocking section 12 is movable relative to the lure body 4 by means of a spring 14. The rocking part 12 is movably mounted on the body 4 by means of a spring 14.

Fig. 4 is a section along IV-IV of fig. 3. In fig. 4, the direction indicated by the arrow X is the front of the lure 2, and the opposite direction is the rear of the lure 2. The direction indicated by the arrow Y is the right of the lure 2, and the opposite direction is the left of the lure 2. The direction perpendicular to the paper surface is the up-down direction of the lure 2.

In this embodiment, a plate portion 42 is provided as the movable region restricting mechanism 16. As shown in fig. 4, there is a first plate portion 42a and a second plate portion 42 b. Each plate portion 42 is plate-shaped. The first plate portion 42a protrudes from the inner surface on the right side of the lure body 4 toward the second rocking section 12b in the vicinity of the center in the up-down direction of the second rocking section 12 b. The second plate portion 42b protrudes from the inner surface on the left side of the lure body 4 toward the second rocking section 12b in the vicinity of the center in the up-down direction of the second rocking section 12 b. The second rocking section 12b is located in a gap between the end of the first plate section 42a on the second rocking section 12b side and the end of the second plate section 42b on the second rocking section 12b side. Although not shown, the first and third rocking sections 12a and 12c are also located in the gap between the first and second plate sections 42a and 42b, respectively. When the rocking section 12 is at rest in the normal posture in which the lure 2 plays, the rocking section 12 does not contact the plate portion 42. When the rocking section 12 operates, the rocking section 12 can contact the plate section 42. The plate portion 42 limits the movable range of the rocking section 12 in the left-right direction. The plate portion 42 has transparency to such an extent that the rocking portion 12 can be visually confirmed from the outside of the lure body 4.

In this embodiment, the movable region restricting mechanism 16 further includes a hole 30 and a lever 44 provided in the pivot portion 12. The rod 44 is fixed to the body 4. The stem 44 spans in the left-right direction within the main cavity 24. The rod 44 passes through the hole 30 of the rocking section 12. The rod 44 passes through each hole 30 of each rocking section 12. The stem 44 has an outer diameter smaller than the inner diameter of the bore 30 of the rocking section 12. When the rocking section 12 is at rest in the normal posture in which the lure 2 plays, the rod portion 44 does not contact the inner surface of the hole 30 of the rocking section 12. When the rocking section 12 is operated, the rocking section 12 can be in contact with the inner surface of the hole 30 of the rod 44. The lever 44 limits the movable range of the rocking section 12 in the front-rear vertical direction. Each rod portion 44 has transparency to such an extent that the rocking section 12 can be visually confirmed from the outside of the lure body 4.

Fig. 5 shows an enlarged part of the tail portion 22 of the lure body 4 of fig. 2. The masking means 18 is provided on a part of the tail portion 22 of the lure body 4. In this embodiment, the shielding mechanism 18 has a secondary cavity 46, an inner air passage 48, an outer air passage 50, and an orifice blocking mechanism 52.

The secondary cavity 46 is located inside the tail 22 of the body 4. The secondary cavity 46 is adjacent to the primary cavity chamber 24. The wall that shields the primary cavity 24 from the secondary cavity 46 is referred to as a shield wall 54. In other words, the lure body 4 further has a shielding wall 54. The secondary cavity 46 has a forward portion 56, an aft portion 58 and an intermediate air passage 60. The front portion 56 is adjacent the primary cavity 24. The rear portion 58 is located rearward of the front portion 56. An intermediate duct 60 is located between the front 56 and rear 58 portions. The intermediate duct 60 is a hole that communicates the front and rear portions 56, 58.

An internal air passage 48 is located between the primary cavity 24 and the secondary cavity 46. The inner air duct 48 extends through the shield wall 54. The internal air passage 48 is a hole communicating the primary cavity 24 and the secondary cavity 46. An outer air duct 50 is located behind the secondary cavity 46. The outer duct 50 is a hole communicating the sub-cavity 46 and the outside. The primary cavity 24 can communicate with the outside through an inner air passage 48, a secondary cavity 46, and an outer air passage 50.

The hole-closing mechanism 52 is composed of an inner lid 62, a screw 64, and a hole 66 provided in the lure body 4. The inner lid 62 is located within the secondary cavity 46. The front surface of the inner lid 62 is disposed along the shielding wall 54. The front surface of the inner lid 62 is in contact with the shielding wall 54. Although not shown, the inner lid 62 has a threaded hole extending downward from the upper surface. The inner surface of the threaded hole is provided with a thread groove. The hole 66 is disposed above the threaded hole. The bore 66 extends from the exterior to the secondary cavity 46. Screw 64 has a head portion 67 and a body portion 68. The head portion 67 has an outer diameter larger than that of the body portion 68. A screw groove is provided on the outer periphery of the body portion 68. The screw 64 is inserted into the hole 66 from the outside. The body portion 68 is inserted through the hole 66 and into a threaded hole of the inner lid 62. The head 67 is exposed to the outer surface. The screw 64 can be rotated from the outside. When the screw 64 is rotated from the outside, the inner lid 62 is not rotated due to contact with the shielding wall 54. By turning the screw 64, the inner lid 62 is moved in the up-down direction. The screw 64, the inner lid 62, and the shielding wall 54 constitute a so-called ball screw.

In the lure 2, the inner lid 62 is moved up and down, so that it is possible to switch between a state in which the main cavity 24 is shielded from the outside and a state in which the main cavity 24 communicates with the outside. In FIG. 5, the inner cover 62 is positioned rearward of the inner air duct 48. In this state, the inner lid 62 closes the inner air passage 48. The primary cavity 24 is shielded from the outside. In fig. 6, the inner lid 62 is moved in an upward direction by turning the screw 64. In this state, the inner lid 62 does not close off the inner air passage 48. The inner air passage 48 is in an open state. The primary cavity 24 communicates with the secondary cavity 46, and the secondary cavity 46 communicates with the outside through an outer air duct 50. In this state, the primary cavity 24 communicates with the outside through the inner air duct 48, the secondary cavity 46, and the outer air duct 50.

In the lure 2, the internal pressure of the main cavity 24 can be made lower than the atmospheric pressure by using the shielding mechanism 18. For this purpose, a vacuum device not shown is used. In a state where the main cavity 24 is in communication with the outside as shown in fig. 6, air in the main cavity 24 is sucked from the outer air duct 50 by a vacuum. Accordingly, the main cavity 24 is depressurized. In this state, the screw 64 is turned to lower the inner lid 62 downward. As shown in fig. 5, the inner cover 62 closes off the inner air passage 48, whereby the main cavity 24 is shielded from the outside. The shutter mechanism 18 switches the main cavity 24 from a state of communicating with the outside to a state of shielding the main cavity 24 from the outside. Accordingly, the main cavity 24 remains in a reduced pressure state even if the vacuum is removed. In this lure 2, the pressure of the main cavity 24 can be maintained in a state of being decompressed compared with the atmospheric pressure. As the vacuum apparatus, a commercially available electric vacuum pump, a manual vacuum pump, or the like can be used.

In the lure 2, a gas having a smaller specific gravity than air (referred to as a low specific gravity gas) can be enclosed in the main cavity 24 by using the shielding mechanism 18. For this purpose, a vacuum device not shown and a gas cylinder storing a low specific gravity gas are used. In a state where the main cavity 24 is in communication with the outside as shown in fig. 6, air in the main cavity 24 is sucked from the outer air duct 50 by a vacuum. The screw 64 is turned to lower the inner lid 62 downward. As shown in fig. 5, the inner cover 62 closes off the inner air passage 48, whereby the main cavity 24 is shielded from the outside. In this state, the gas cylinder is communicated with the external air passage 50. Turning the screw 64 raises the inner lid 62 upwardly to fill the main cavity 24 with low specific gravity gas from the gas cylinder. At this time, the internal pressure of the main cavity 24 is generally equal to or lower than the atmospheric pressure. The screw 64 is turned again to lower the inner lid 62 downward. Accordingly, the low specific gravity gas is enclosed in the main cavity 24. Helium is exemplified as the low specific gravity gas.

In the lure 2, the air pressure in the main cavity 24 can be reduced compared with the normal atmospheric pressure. Alternatively, a low specific gravity gas can be enclosed within the main cavity 24. In the lure 2, in order to maintain this state, the right and left halves of the lure body 4 are welded or bonded. The contacting portions of the right and left halves of the lure body 4 may also be sealed with rubber.

A not shown counterweight body is located within the main cavity 24. The balance weight adjusts the posture of the lure 2 when the lure 2 is made to swim.

The operation and effect of the present invention will be described below.

The lure 2 according to the present invention has a rocking section 12 for receiving light from the outside and emitting the light in a main cavity 24 of a lure body 4. The oscillating portion 12 is a reflector. The surface of the oscillating portion 12 reflects light. The lure body 4 has a degree of transparency to allow light to penetrate into the primary cavity 24. The light reflected by the oscillating portion 12 can be visually recognized from the outside. The light reflected by the shaking section 12 attracts and attracts the fish. Such a lure 2 can be expected to have a high hook-up rate.

The rocking part 12 of the lure 2 is attached to the lure body 4 by a spring 14. The rocking section 12 rocks back and forth, up and down, and left and right by the spring 14 in an operating state of the lure 2 when the angler pulls the lure 2, when the flow of water, tide, etc. is fast. The reflecting state of light changes by the operation of the oscillating portion 12. The visual state of the light emitted from the oscillating portion 12 changes. The rocking section 12 looks flickering. This can effectively attract fish-attracting fish. Such a lure 2 can be expected to have a high hook-up rate.

The rocking part 12 of the lure 2 is movably attached to the lure body 4 by a spring 14. The spring 14 is operated for a while when the lure 2 is changed from the operating state to the stopped state such as when the angler stops pulling the lure 2, when the flow of water or tide is stopped. The rocking section 12 can rock back and forth, up and down, and left and right for a while even when the lure 2 is brought from the operating state to the stopped state. At this time, the rocking section 12 still looks flickering. The shaking portion 12 can also effectively attract the feeding fishes for a while after the lure 2 becomes in a stopped state. Such a lure 2 can be expected to have a high hook-up rate.

The lure 2 has a shutter mechanism 18, and the shutter mechanism 18 is capable of switching the main cavity 24 from a state in which the main cavity 24 communicates with the outside to a state in which it is shielded from the outside. The internal pressure of the main cavity 24 can be reduced from the atmospheric pressure by sucking the gas in the main cavity 24 from the outside and shielding the main cavity 24 from the outside in this state. In the main cavity 24 that is depressurized, air resistance is reduced compared to the outside. The rocking section 12 can be operated for a long time after the lure 2 is in the stopped state. In the lure 2, after the operation of the lure 2 is stopped, fish-feeding fishes can be effectively attracted.

The lure 2 further has a shutter mechanism 18, and the shutter mechanism 18 is capable of switching the main cavity 24 from a state in which the main cavity 24 communicates with the outside to a state in which it is shielded from the outside. The low specific gravity gas can be sealed in the main cavity 24 by filling the main cavity 24 with the low specific gravity gas and shielding the main cavity 24 from the outside in this state. In the main cavity 24, even if the internal pressure is equal to the atmospheric pressure, the resistance that the oscillating portion 12 receives from the low specific gravity gas when the oscillating portion 12 operates is smaller than the air resistance that the oscillating portion 12 receives when it operates in the same manner in the atmospheric air. Even if the internal pressure of the main cavity 24 is equal to the atmospheric pressure, the rocking section 12 can operate for a long time after the lure 2 is in the stopped state. By setting the internal pressure of the main cavity 24 lower than the atmospheric pressure, the rocking section 12 can be operated for a longer time even after the lure 2 is in the stopped state. In the lure 2, even after the operation of the lure 2 is stopped, fish-feeding fishes can be effectively attracted.

The strength of the spring 14 is adjusted according to the weight of the rocking section 12. If the strength of the spring 14 is strong, the spring 14 does not expand or contract substantially even if the rocking section 12 is attached. If the strength of the spring 14 is weak, the spring 14 located above the rocking section 12 is in a fully expanded state and the spring 14 located below the rocking section 12 is in a fully contracted state when the rocking section 12 is attached. In both cases, vibration is difficult to perform, and the duration of vibration is also shortened. The strength of the spring 14 is appropriately adjusted so that the vibration lasts for a long time. Accordingly, such a lure 2 can be expected to have a high hook-up rate.

It is preferable that the rocking section 12 is installed between the first spring 14a and the second spring 14 b. In this embodiment, the rocking section 12 is sandwiched vertically by the first spring 14a and the second spring 14 b. This can suppress the excessive oscillation of the oscillating portion 12. The oscillating portion 12 can oscillate at a high frequency. The rocking section 12 looks flickering. This can effectively attract fish-attracting fish. Such a lure 2 can be expected to have a high hook-up rate.

As described above, it is preferable that the rocking section 12 has the notch 34, and the spring 14 is attached to the rocking section 12 by inserting the end of the spring 14 into the notch 34. This effectively prevents the spring 14 from falling off the swinging portion 12.

In the lure 2, it is preferable to have a movable region restricting mechanism 16. In this embodiment, the plate portion 42 is provided as the movable region restricting mechanism 16. When the elastic body 14 rocks left and right, the elastic body 14 can contact the plate portion 42. The plate portion 42 restricts the movable range of the elastic body 14 in the left-right direction. As the movable region restricting mechanism 16, a rod portion 44 is further provided which passes through the hole 30 of the rocking section 12. When the elastic body 14 rocks back and forth and up and down, the inner surface of the hole 30 of the rocking section 12 contacts the rod section 44. The lever portion 44 limits the movable range of the elastic body 14 in the front-rear vertical direction. The moving region restricting mechanism 16 prevents the rocking section 12 from being caught in or caught by a structure inside the main cavity 24 due to a large movement of the rocking section 12. The rocking section 12 can be prevented from being fixed at an abnormal position. Further, the oscillation of the oscillating portion 12 is suppressed from becoming excessively large by these movable region restricting mechanisms 16. The oscillating portion 12 can oscillate at a high frequency. The rocking section 12 looks flickering. This can effectively attract fish-attracting fish. Such a lure 2 can be expected to have a high hook-up rate.

As described above, the rocking section 12 rocks back and forth, up and down, left and right for a while even when the lure 2 is in the stopped state from the operating state. The time for which the lure 2 is vibrated is preferably 3 seconds or more, more preferably 5 seconds or more, and further preferably 10 seconds or more.

The lure 70 includes a lure body 72, a projecting portion (lip)74, a rocking portion 76, an elastic body 78, a movable region restricting mechanism 80, and a shielding mechanism 82 described later. Although not shown, the lure 70 further includes a fishing line hole, a fishing hook, and a weight body.

The lure body 72 has an appearance similar to a fishing lure, i.e., a small fish. The lure body 72 is formed of a hard material. Typically, the lure body 72 is formed of a synthetic resin composition. The lure body 72 may also be formed of a soft material such as an elastomer. As shown in fig. 7, the body 72 has a main cavity 84 therein. The lure body 72 has transparency to the extent that light penetrates into the primary cavity 84. Accordingly, the rocking section 76 in the main cavity 84 can be visually recognized from the outside. The light from the oscillating portion 76 can be visually recognized from the outside in the lure body 72.

The lure body 72 has a hooking rod 86 extending from the inner surface. As will be described later, the rocking section 76 is attached to the hooking rod 86 through the elastic body 78. In this embodiment, the hooking levers 86 are provided in front of and behind the swinging portion 76, respectively.

The projection 74 is formed of a hard material. Typically, the protrusion 74 is formed of a synthetic resin composition. As shown in fig. 7, the projections 74 are mounted on the underside of the lure body 72. The projection 74 is located below the head. The projections 74 contribute to a proper underwater posture of the lure 70 while swimming.

As shown in fig. 7, the rocking section 36 is located inside the main cavity 84. The rocking section 76 extends in the front-rear direction. The rocking section 76 has a plate shape. As shown in fig. 7, the rocking section 76 has a hole 88 penetrating in the thickness direction.

The oscillating portion 76 receives light from the outside and emits the light. In this embodiment, the oscillating portion 76 is a reflector. That is, the surface of the oscillating portion 76 reflects light. The surface of the rocking section 76 is glossy. The surface of the rocking section 76 may be colored or a pattern may be added. The oscillating portion 76 is typically formed of a synthetic resin composition. The rocking section 76 may also be formed of metal. A hologram plate (holoplate) is exemplified as a typical oscillating portion 76. The oscillating portion 76 may be a phosphor.

Fig. 8 shows an enlarged view of the vicinity of the front end of the oscillating portion 76 in fig. 7. Fig. 8 differs from fig. 7 in the direction in which the lure 70 is observed. In fig. 8, the direction indicated by the arrow X is the front of the lure 70, and the opposite direction is the rear of the lure 70. The direction indicated by the arrow Y is the right of the lure 70, and the opposite direction is the left of the lure 70. The direction indicated by the arrow Z is above the lure 70, and the opposite direction is below the lure 70.

As shown in fig. 7 and 8, the rocking section 76 has notches 90 at its front and rear end portions. As shown in fig. 7, a first notch 90a extending from an upper end and a second notch 90b extending from a lower end are provided at the front end portion and the rear end portion, respectively. A portion divided by the first notch 90a and the second notch 90b is referred to as a fixing portion 92. As shown in fig. 7, the fixing portion 92 has a head portion 94 located at an end in the front-rear direction and a neck portion 96 having a width narrower than the head portion 94.

The elastomer 78 is located within the main cavity 84. In this embodiment, the elastic body 78 is a spring 78. As shown in fig. 7, there are a first spring 78a located in front of the rocking section 76 and a second spring 78b located behind the rocking section 76. The first spring 78a and the second spring 78b extend in the front-rear direction, respectively.

As shown in fig. 8, the front end of the first spring 78a is annular. The ring 98 is hooked to the hooking rod 86. As shown in fig. 8, the rear end of the first spring 78a is double-looped. The double ring 100 is inserted into the notch 90 on the distal end side. The double ring 100 is hooked on the neck portion 96 of the fixing portion 92 on the distal end side. The rear end of the second spring 78b is a ring 98. The ring 98 is hooked to the hooking rod 86. The front end of the second spring 78b is double-looped. The double ring 100 is inserted into the notch 90 on the rear end side. The double ring 100 is hooked on the neck portion 96 of the fixing portion 92 on the rear end side. The rocking section 76 is installed between the first spring 78a and the second spring 78 b. The rocking section 76 can be vibrated with respect to the lure body 72 by the spring 78. The swinging portion 76 can swing back and forth, up and down, and right and left by the spring 78. The rocking section 76 is movable relative to the lure body 72 by the spring 78. The rocking section 76 is movably mounted on the lure body 72 by a spring 78.

As shown in fig. 7, in this embodiment, a hole 88 and a lever 102 provided in the pivot portion 76 are provided as the movable region restricting mechanism 80. The rod portion 102 is secured to the decoy body 72. The stem 102 spans in the left-right direction within the main cavity 84. The stem 102 passes through the aperture 88 of the rocking section 76. The stem 102 has an outer diameter smaller than the inner diameter of the bore 88 of the rocking section 76. When the rocking section 76 is at rest in the normal posture in which the lure 70 plays, the lever portion 102 does not contact the inner surface of the hole 88 of the rocking section 76. When the rocking section 76 operates, the rocking section 76 can contact the rod 102. The lever 102 limits the movable range of the rocking section 76 in the front-rear vertical direction. The rod portion 102 has transparency to such an extent that the rocking portion 76 can be visually confirmed from the outside of the lure body 72.

Although not shown, in this embodiment, a plate portion is further provided as the movable region restricting means 80. The first and second plate portions are located inside the main cavity 84. The first plate portion protrudes from the inner surface on the right side of the lure body 72 toward the rocking portion 76 in the vicinity of the center in the vertical direction of the rocking portion 76. The second plate portion protrudes from the inner surface on the left side of the lure body 72 toward the rocking portion 76 in the vicinity of the center in the vertical direction of the rocking portion 76. The rocking section 76 is located in a gap between the end of the first plate section on the rocking section 76 side and the end of the second plate section on the rocking section 76 side. When the rocking section 76 is at rest in the normal posture in which the lure 70 travels, the rocking section 76 does not contact the plate section. When the rocking section 76 operates, the rocking section 76 can contact the plate section. The plate portion restricts the movable range of the swinging portion 76 in the left-right direction. Each plate portion has transparency to the extent that the rocking portion 76 can be visually confirmed from the outside of the lure body 72.

Fig. 9 is a sectional view showing a rear portion of the lure 70 of fig. 7. Fig. 9 shows a part of the tail 104 of the lure 70. In this figure, a masking mechanism 82 of the lure 70 is shown. In this embodiment, the shielding mechanism 82 includes a sub-cavity 106, an inner air duct 108, an outer air duct 110 (see fig. 10), and a hole blocking mechanism 112.

The secondary cavity 106 is located inside the tail 104 of the decoy body 72. The secondary cavity 106 is adjacent to the primary cavity chamber 84. The wall that shields the primary cavity 84 from the secondary cavity 106 is referred to as a shield wall 114. In other words, the lure body 72 also has a shielding wall 114. An internal air passage 108 is located between the primary cavity 84 and the secondary cavity 106. The inner duct 108 extends through the shield wall 114. The internal air passage 108 is a hole communicating the primary cavity 84 and the secondary cavity 106. The outer air duct 110 is located rearward of the secondary cavity 106. The outer gas duct 110 is a hole communicating the sub-cavity 106 and the outside. The primary cavity 84 can communicate with the outside through an inner air passage 108, a secondary cavity 106, and an outer air passage 110.

The hole plugging mechanism 112 has an inner lid 116, a support portion 118, a sealing spring 120, and an outer plug 122. The inner cover 116 has a seal plate 124 and a shaft portion 126. As shown in fig. 9, the front surface of the sealing plate 124 is disposed along the shielding wall 114. The front surface of the sealing plate 124 is in contact with the shielding wall 114. The shaft portion 126 extends rearward from the seal plate 124.

The bearing portion 118 is located rearward of the inner lid 116. The support portion 118 is fixed to the lure body 72. The support portion 118 has a hole 128 extending in the front-rear direction. The shaft portion 126 of the inner lid 116 is inserted into the hole 128. Accordingly, the inner lid 116 is attached to the support portion 118 so as to be movable in the front-rear direction.

A sealing spring 120 is located between the inner lid 116 and the bearing 118. As shown in fig. 9, the shaft portion 126 passes through the inside of the seal spring 120. The sealing spring 120 has a front end contacting the inner lid 116 and a rear end contacting the bearing 118. The sealing spring 120 presses the inner lid 116 toward the inner air passage 108 side. In the state shown in fig. 9, the inner lid 116 closes off the inner air passage 108.

The outer plug 122 has a cap portion 130 and a push shaft 132. The cap part 130 covers the tail part 104 from the rear side of the lure 70. Accordingly, the cap portion 130 blocks the outer duct 110. The pushing shaft 132 extends forward from the end cap portion 130. The push shaft 132 is inserted into the outer duct 110. The pressing shaft 132 is inserted into the hole 128 of the support 118 through the outer duct 110. The push shaft 132 is in contact with the shaft portion 126 of the inner lid 116. The pushing shaft 132 pushes the inner lid 116. The outer plug 122 is freely mounted on the tail portion 104 and removed from the tail portion 104. The outer plug 122 is removably attachable to the tail 104.

In the lure 70, the internal pressure of the main cavity 84 can be made lower than the atmospheric pressure by using the shielding mechanism 82. For this purpose, a vacuum is used. The outer plug 122 is removed from the tail 104 and air inside the secondary cavity 106 is drawn from the outer air duct 110 using a vacuum. The force of the suction force moving the inner lid 116 backward is larger than the force of the seal spring 120 pressing the inner lid 116 forward. The inner lid 116 moves rearward (opposite to the inner air duct 108), and the inner air duct 108 is opened. The primary cavity 84 and the secondary cavity 106 communicate through an internal air passage 108. The primary cavity 84 communicates with the exterior through an inner air passage 108, a secondary cavity 106, and an outer air passage 110. This state is shown in fig. 10 (a). The main cavity 84 is depressurized by drawing air inside the main cavity 84 using a vacuum.

With the main cavity 84 depressurized, the suction of the vacuum is stopped. The inner lid 116 is moved toward the inner air passage 108 side by the force of the seal spring 120. The main cavity 84 is shielded from the outside by the inner cover 116 closing off the inner air passage 108. The shielding mechanism 82 converts the main cavity 84 from a state of communicating with the outside to a state of being shielded and partitioned between the main cavity 84 and the outside. This state is shown in fig. 10 (B). As shown in fig. 9, the outer plug 122 further overlies the tail 104. The pressing shaft 132 of the outer plug 122 contacts the shaft portion 126 of the inner cap 116. The pressing shaft 132 of the outer plug 122 presses and fixes the inner cap 116 forward. Accordingly, the main cavity 84 is maintained in a depressurized state. In this lure 70, the main cavity 84 can be maintained in a state of being decompressed compared with the atmospheric pressure.

In this lure 70, the air pressure in the main cavity 84 can be reduced compared with the normal atmospheric pressure. In the lure 70, in order to maintain this state, the right and left halves of the lure body 72 are welded or bonded. The contacting portions of the right and left halves of the lure body 72 may also be sealed with rubber.

The operation and effect of the present invention will be described below.

The lure 70 according to the present invention has a rocking section 76 that receives light from the outside and emits the light in the main cavity 84 of the lure body 72. The oscillating portion 76 is a reflector. The surface of the oscillating portion 76 reflects light. The lure body 72 has a degree of transparency that allows light to penetrate into the primary cavity 84. The light reflected by the oscillating portion 76 can be visually confirmed from the outside. The light reflected by the shaking section 76 attracts fish-eating fish. Such a lure 70 can be expected to have a high hooking rate.

The rocking section 76 of the lure 70 is attached to the lure body 72 by a spring 78. The swinging portion 76 swings back and forth, up and down, and left and right by the spring 78 in an operating state of the lure 70 such as when the angler pulls the lure 70, when the flow of water or tide is fast. The reflecting state of light changes by the operation of the oscillating portion 76. The visual state of the light emitted from the oscillating portion 76 changes. The rocking section 76 looks like flickering. This can effectively attract fish-attracting fish. Such a lure 70 can be expected to have a high hooking rate.

The rocking section 76 of the lure 70 is movably attached to the lure body 72 by a spring 78. The spring 78 can be operated for a while when the lure 70 is changed from the operating state to the stopped state, such as when the angler stops pulling the lure 70, when the flow of water or tide is stopped. The swinging part 76 can swing back and forth, up and down, left and right for a while even when the lure 70 is in the stopped state from the operating state. At this time, the rocking section 76 still looks blinking. The shaking portion 76 can also effectively attract the feeding fish for a while after the lure 70 is brought into a stopped state. Such a lure 70 can be expected to have a high hooking rate.

The lure 70 has a shutter mechanism 82, and the shutter mechanism 82 is capable of switching the main cavity 84 from a state in which the main cavity 84 communicates with the outside to a state in which it is shielded from the outside. The internal pressure of the main cavity 84 can be reduced compared with the atmospheric pressure by sucking the gas in the main cavity 84 from the outside and shielding the main cavity 84 from the outside in this state. In the depressurized main cavity 84, the air resistance is reduced compared to the outside. The oscillating portion 76 can also operate for a longer time. In the lure 70, after the operation of the lure 70 is stopped, fish-feeding fish can be effectively attracted.

It is preferable that the rocking section 76 is installed between the first spring 78a and the second spring 78 b. In this embodiment, the rocking section 76 is sandwiched forward and backward by the first spring 78a and the second spring 78 b. This can suppress the excessive oscillation of the oscillating portion 76. The oscillating portion 76 can oscillate at a high frequency. The rocking section 76 looks like flickering. This can effectively attract fish-attracting fish. Such a lure 70 can be expected to have a high hooking rate.

The lure 70 preferably has a movable region restricting mechanism 80. The movable region restricting mechanism 80 prevents the rocking section 76 from being caught in or caught by a structure inside the main cavity 84 due to a large operation of the rocking section 76. The rocking section 76 can be prevented from being fixed at an abnormal position. Further, the oscillation of the oscillating portion 76 is suppressed from becoming excessively large by the movable region restricting mechanism 80. The oscillating portion 76 can oscillate at a high frequency. The rocking section 76 looks like flickering. This can effectively attract fish-attracting fish. Such a lure 70 can be expected to have a high hooking rate.

[ third embodiment ]

Fig. 11 (a) and (B) show a lure 140 according to another embodiment of the present invention. These are enlarged sectional views of the rear part of the right side part when the lure 140 is divided into left and right parts. In these figures, a part of the tail 142 of the lure 140 is shown. In fig. 11 (a) and (B), the direction indicated by the arrow X is the front of the lure 140, and the opposite direction is the rear of the lure 140. The direction indicated by the arrow Z is above the lure 140, and the opposite direction is below the lure 140. The direction perpendicular to the paper surface is the left-right direction of the lure 140.

The lure 140 has a lure body 144, a fishing line hole, a fishing hook hole, a weight body, a swinging portion, an elastic body, a movable region restricting mechanism, and a shielding mechanism 146. In this lure 140, the structures of the parts other than the shielding mechanism 146 are the same as those of the corresponding parts in the lure 2 of fig. 2 to 4.

Fig. 11 (a) and (B) show the shielding mechanism 146. In this embodiment, the masking mechanism 146 has a secondary cavity 148, an inner airway 150, an outer airway 152, and an orifice blocking mechanism 154.

The secondary cavity 148 is located inside the tail 142 of the decoy body 144. The secondary cavity 148 is adjacent to the primary cavity chamber 156. The wall that shields the primary cavity 156 from the secondary cavity 148 is referred to as a shield wall 158. In other words, the lure body 144 has a shielding wall 158. The secondary cavity 148 has a forward portion 160, an aft portion 162, and an intermediate air passage 164. The front portion 160 is adjacent the primary cavity 156. The rear portion 162 is located rearward of the front portion 160. An intermediate air passage 164 is located between the forward portion 160 and the rearward portion 162. The intermediate air passage 164 is a hole that communicates the front portion 160 and the rear portion 162.

The internal air passage 150 is located between the primary cavity 156 and the secondary cavity 148. The inner air duct 150 penetrates the shielding wall 158. The internal air passage 150 is a hole that communicates the primary cavity 156 and the secondary cavity 148. An outer air passage 152 is located rearward of the secondary cavity 148. The outer air passage 152 is a hole communicating the sub-cavity 148 and the outside. The primary cavity 156 can communicate with the outside through the inner air passage 150, the secondary cavity 148, and the outer air passage 152.

The hole-closing mechanism 154 is constituted by a hole 166 provided on the lure body 144, an inner lid 168 and an O-ring 170. The bore 166 extends from the exterior to the secondary cavity 148. As shown in fig. 11 (a), the inner wall of the hole 166 and the surface of the rear side of the shielding wall 158 are continuous. The inner lid 168 is inserted into the hole 166 from the outside. Fig. 11 (a) shows a state in which a part of inner lid 168 is inserted into hole 166, but inner lid 168 does not reach inner air duct 150. At this time, inner cap 168 does not seal off internal air passageway 150. The internal air path 150 is in an open state. In this state, the primary cavity 156 communicates with the secondary cavity 148. In this state, the main cavity 156 communicates with the outside through the inner air duct 150, the sub-cavity 148, and the outer air duct 152. As shown in fig. 11 (B), when inner lid 168 is inserted into hole 166 to a position covering inner air duct 150, inner lid 168 blocks inner air duct 150. The primary cavity 156 is shielded from the outside. An O-ring 170 is mounted on the inner surface of the bore 166. In the state of fig. 11 (a), the O-ring 170 closes the gap between the inner surface of the hole 166 and the inner lid 168.

In this embodiment, when inner lid 168 is inserted into hole 166, the outer surface of inner lid 168 is coated with a solvent. By inserting inner lid 168 into hole 166 up to the state of fig. 11 (B) and maintaining this state, the solvent dissolves the outer surface of inner lid 168 and the inner surface of hole 166. Accordingly, the outer surface of inner cap 168 engages the inner surface of bore 166. As a material of the inner lid 168 and the tail portion 142, ABS resin is exemplified. As the solvent, methyl ethyl ketone is exemplified. The outer surface of inner cap 168 and the inner surface of bore 166 may also be joined by an adhesive.

In the lure 140, the internal pressure of the main cavity 156 can be made lower than the atmospheric pressure by using the masking mechanism 146. For this purpose, a vacuum is used. In a state where the main cavity 156 shown in fig. 11 (a) is in communication with the outside, air inside the main cavity 156 is sucked from the outer air duct 152 using a vacuum. Accordingly, the main cavity 156 is depressurized. In this state, inner lid 168 is inserted to the position shown in fig. 11 (B). The inner lid 168 closes off the inner air passage 150, whereby the main cavity 156 is shielded from the outside. The shutter mechanism 146 switches the main cavity 156 from a state of communicating with the outside to a state of being shielded and separated between the main cavity 156 and the outside. Accordingly, the main cavity 156 remains in a reduced pressure state even if the vacuum is removed. In this lure 140, the main cavity 156 can be maintained in a state of being decompressed compared with the atmospheric pressure.

In this lure 140, the low specific gravity gas can be enclosed in the main cavity 156 by using the shielding mechanism 146. For this purpose, a vacuum, a gas cylinder storing a low specific gravity gas, and a switching valve, all of which are not shown, are used. The vacuum and the gas cylinder are connected to the external air passage 152 through a switching valve. The vacuum communicates with the external air passage 152 by the switching valve, and the cylinder is shielded from the external air passage 152. In a state where the main cavity 156 shown in fig. 11 (a) is in communication with the outside, air inside the main cavity 156 is sucked from the outer air duct 152 using a vacuum. The switching valve is switched to communicate the gas cylinder with the external air passage 152, and the vacuum is shielded from the external air passage 152. The low specific gravity gas is filled from the gas cylinder into the main cavity 156. At this time, the internal pressure of the main cavity 24 is generally equal to or lower than atmospheric pressure. In this state, inner lid 168 is inserted to the position shown in fig. 11 (B). The inner lid 168 closes off the inner air passage 150, whereby the main cavity 156 is shielded from the outside. Accordingly, the low specific gravity gas is enclosed in the main cavity 156.

The shaking portion of the lure 140 is movably mounted on the lure body 144 by means of a spring. The spring 78 can be operated for a while when the lure 140 is changed from the operating state to the stopped state such as when the angler stops pulling the lure 140, when the flow of water or tide is stopped, or the like. The lure 140 has a shielding mechanism 146, and the shielding mechanism 146 can switch the main cavity 156 from a state in which the main cavity 156 communicates with the outside to a state in which it is shielded from the outside. The internal pressure of the main cavity 156 can be reduced from the atmospheric pressure by sucking the gas in the main cavity 156 from the outside and shielding the main cavity 156 from the outside in this state. Alternatively, the low specific gravity gas can be enclosed in the main cavity 156 by introducing the low specific gravity gas into the main cavity 156 and shielding the main cavity 156 from the outside in this state. In these main cavities 156, the resistance of the oscillating portion from the gas in the main cavity 156 is small when the oscillating portion operates, and therefore the oscillating portion can operate for a longer time. In the lure 140, after the operation of the lure 140 is stopped, fish-feeding fish can be effectively attracted.

[ fourth embodiment ]

Fig. 12 (a) and (B) show a lure 180 according to another embodiment of the present invention. These are enlarged cross-sectional views of the rear part of the right side part when the lure 180 is divided into left and right parts. In fig. 12 (a) and (B), the direction indicated by the arrow X is the front of the lure 180, and the opposite direction is the rear of the lure 180. The direction indicated by the arrow Z is above the lure 180, and the opposite direction is below the lure 180. The direction perpendicular to the paper surface is the left-right direction of the lure 180.

The lure 180 includes a lure body 182, a fishing line hole, a fishing hook hole, a weight body, a swinging portion, an elastic body, a movable region restricting mechanism, and a shielding mechanism 184. In this lure 180, the structures of the parts other than the lure body 182 and the shielding means 184 are the same as those of the corresponding parts in the lure 2 of fig. 1.

The lure body 182 has an appearance similar to a fishing lure, i.e., a small fish. The lure body 182 is formed of a hard material. Typically, the lure body 182 is formed of a synthetic resin composition. The lure body 182 may also be formed of a soft material such as an elastomer. In this lure 180, the lure body 182 has a main portion 186 and a sub-portion 188. Fig. 12 (a) and (B) show a boundary portion between the main portion 186 and the sub portion 188.

As shown in fig. 12 (a) and (B), the main portion 186 has a main cavity 190 inside. The main portion 186 has transparency to the extent that light penetrates into the main cavity 190. Accordingly, the oscillating portion in the main cavity 190 can be visually recognized from the outside. The light from the oscillating portion can be visually recognized from the outside in the lure body 182. The secondary portion 188 is located rearward of the primary portion 186. The secondary portion 188 has a secondary cavity 192 therein. The wall on the side of the secondary portion 188 of the primary portion 186 is referred to as a primary partition wall 194. The wall of the sub portion 188 on the main portion 186 side is referred to as a sub partition wall 196. The primary partition wall 194 faces the secondary partition wall 196.

In the lure 180, the shielding means 184 is constituted by the above-described sub-cavity 192, main portion hole 198, sub-portion hole 200, attachment portion 202, O-ring 204, and external air duct, not shown. A main portion hole 198 is provided on the main partition wall 194. The main section hole 198 passes through the main partition wall 194 to reach the main cavity 190. The sub portion hole 200 is provided to the sub partition wall 196. The secondary portion hole 200 extends through the secondary partition wall 196 to the secondary cavity 192. The mounting portion 202 extends from the primary cavity 190 through the primary and secondary partition walls 194, 196 to the secondary cavity 192. The secondary section 188 is attached to the primary section 186 by the attachment section 202. The sub portion 188 can rotate about the mounting portion 202. The secondary portion 188 is rotatable relative to the primary portion 186. An O-ring 204 is located between the primary and secondary partition walls 194, 196. An O-ring 204 is mounted on the main dividing wall 194. An O-ring 204 is attached to the main partition wall 194 so as to surround the opening of the main portion hole 198. An outer duct, not shown, communicates the secondary cavity 192 with the outside.

As shown in fig. 12 (a), the position of the main portion hole 198 and the position of the sub portion hole 200 can be aligned. At this time, the primary cavity 190 and the secondary cavity 192 communicate through the primary portion hole 198 and the secondary portion hole 200. At this time, the main portion hole 198 and the sub portion hole 200 form an inner air passage communicating the main cavity 190 and the sub cavity 192. The primary cavity 190 communicates with the outside through the inner air passage, the secondary cavity 192, and the outer air passage. As shown in fig. 12 (B), the main cavity 190 and the sub cavity 192 are shielded and separated by shifting the position of the main hole 198 and the position of the sub hole 200 by rotating the sub portion 188. The inner air passage communicating the primary cavity 190 and the secondary cavity 192 disappears. The primary cavity 190 is shielded from the outside.

In the lure 180, the internal pressure of the main cavity 190 can be made lower than the atmospheric pressure by using the shielding mechanism 184. For this purpose, a vacuum is used. In a state where the main cavity 190 shown in fig. 12 (a) communicates with the outside, air inside the main cavity 190 is sucked from the outside air duct by a vacuum. Accordingly, the main cavity 190 is depressurized. In this state, the sub portion 188 rotates. As shown in fig. 12 (B), the inner air duct is no longer present, and the main cavity 190 is shielded from the outside. The shielding mechanism 184 converts the main cavity 190 from a state of communicating with the outside to a state of being shielded and separated between the main cavity 190 and the outside. Accordingly, the main cavity 190 is maintained in a reduced pressure state even if the vacuum is removed. In this lure 180, the main cavity 190 can be maintained in a state of being decompressed compared with the atmospheric pressure.

In the lure 180, the low specific gravity gas can be enclosed in the main cavity 190 by filling the main cavity 190 with the low specific gravity gas in a state where the inner air passage is formed and the main cavity 190 communicates with the outside and then eliminating the inner air passage.

The shaking portion of the lure 180 is movably mounted on the lure body 182 by means of a spring. The spring can be operated for a while when the lure 180 is changed from the operating state to the stopped state when the angler stops pulling the lure 180, when the flow of water, tide, etc. The lure 180 includes a shielding mechanism 184, and the shielding mechanism 184 can switch the main cavity 190 from a state in which the main cavity 190 communicates with the outside to a state in which the main cavity 190 is shielded from the outside. The internal pressure of the main cavity 190 can be reduced from the atmospheric pressure by sucking the gas in the main cavity 190 from the outside and shielding the main cavity 190 from the outside in this state. Alternatively, the low specific gravity gas may be introduced into the main cavity 190 and the main cavity 190 may be shielded from the outside in this state, thereby enclosing the gas in the main cavity 190. In these main cavities 190, the resistance that the oscillating portion receives from the gas in the main cavities 190 when the oscillating portion operates is small. The rocking section can operate for a longer time. In the lure 180, after the operation of the lure 180 is stopped, fish-feeding fish can be effectively attracted.

[ fifth embodiment ]

Fig. 13 shows a lure 210 according to another embodiment of the present invention. Fig. 13 is an enlarged exploded view of the front part of the right side portion when the lure 210 is divided into left and right portions. In the figure, a portion which is in contact with the left half portion of the lure 210 when the left half portion is mounted is shaded. In fig. 13, the direction indicated by the arrow X is the front of the lure 210, and the opposite direction is the rear of the lure 210. The direction shown by the arrow Z is above the lure 210, and the opposite direction is below the lure 210. The direction perpendicular to the paper surface is the left-right direction of the lure 210.

The lure 210 has a lure body 212, a projection 214, a fishing line hole, a fishing hook, a weight body, a rocking part 216, an elastic body 218, a movable region restricting mechanism 220, and a shielding mechanism. In this lure 210, the structure of the members other than the elastic body 218 is the same as that of the corresponding members in the lure 70 of fig. 7.

The elastomer 218 is located inside the main cavity 222. In this embodiment, the elastomer 218 is rubber 218. As shown in fig. 13, there are a first rubber 218a located in front of the oscillating portion 216 and a second rubber 218b located behind the oscillating portion 216. The first rubber 218a and the second rubber 218b extend in the front-rear direction, respectively.

The front end of the first rubber 218a is annular. The loop is hooked on the hooking rod 224. The rear end of the first rubber 218a is annular. The ring-shaped ring is inserted into the notch 226 on the tip side. The ring is hooked on the neck portion of the fixing portion 228 on the front end side. The rear end of the second rubber 218b is annular. The annular ring is hooked on the hooking rod 224. The front end of the second rubber 218b is annular. The annular ring is inserted into the rear end side notch 226. The ring is hooked on the neck portion of the fixing portion 228 on the rear end side. The rocking section 216 is installed between the first rubber 218a and the second rubber 218 b. The shaking portion 216 can be vibrated with respect to the lure body 212 by the rubber 218. The swinging portion 216 can swing back and forth, up and down, and right and left by the rubber 218. The shaking portion 216 is movable relative to the lure body 212 by the rubber 218. The shaking portion 216 is movably mounted on the lure body 212 by rubber 218.

The lure 210 has a rocking section 216 that receives light from the outside and emits the light in a main cavity 222 of the lure body 212. The oscillating portion 216 is a reflector. The surface of the oscillating portion 216 reflects light. The bait body 212 has a degree of transparency that allows light to penetrate into the primary cavity 222. The light reflected by the oscillating portion 216 can be visually recognized from the outside. The light reflected by the shaking section 216 attracts fish-eating fish. Such a lure 210 can be expected to have a high hooking rate.

The shaking portion 216 of the lure 210 is attached to the lure body 212 via rubber 218. The rocking section 216 rocks back and forth, up and down, and left and right through the rubber 218 in an operating state of the lure 210 such as when the angler pulls the lure 210, or when the flow of water or tide is fast. The reflecting state of light changes by the operation of the oscillating portion 216. The visual state of the light emitted by the oscillating portion 216 changes. The rocking section 216 looks like flickering. This can effectively attract fish-attracting fish. Such a lure 210 can be expected to have a high hooking rate.

The shaking portion 216 of the lure 210 is movably mounted to the lure body 212 via a rubber 218. When the fishing person stops pulling the lure 210, or when the flow of water or tide stops, or when the lure 210 is in a stopped state from an operating state, the rubber 218 can still rock back and forth, up and down, left and right for a while. At this time, the rocking section 216 still looks blinking. The shaking part 216 can also effectively attract the feeding fishes for a while after the lure 210 is brought into a stopped state. Such a lure 210 can be expected to have a high hooking rate.

[ other embodiments ]

The shielding mechanism is not limited to the above embodiment. The shielding means may be configured to switch the main cavity from a state in which the main cavity communicates with the outside to a state in which the main cavity is shielded from the outside. Accordingly, the inside of the main cavity is depressurized in a state where the main cavity communicates with the outside, and the main cavity is shielded from the outside, whereby the main cavity can be maintained in a depressurized state. Alternatively, the low specific gravity gas may be enclosed in the main cavity by filling the main cavity with the low specific gravity gas in a state where the main cavity is in communication with the outside, and then shielding the main cavity from the outside.

The lure may also be provided without a masking means to depressurize the main cavity. In this case, as an example of a method for obtaining the main cavity which is depressurized compared with the atmospheric pressure, there is a method for assembling the lure in an atmosphere which is depressurized compared with the atmospheric pressure. For example, the lure is divided into a right half portion and a left half portion in advance, and the right half portion and the left half portion are welded together in a container depressurized compared to atmospheric pressure. The main cavity can be maintained in a decompressed state by configuring the main cavity after welding to be shielded and separated from the outside.

The lure may be provided without a masking means and a low specific gravity gas is enclosed in the main cavity. In this case, as an example of a method for obtaining the main cavity in which the low specific gravity gas is sealed, there is a method for assembling the lure in an atmosphere of the low specific gravity gas. For example, the lure is divided into a right half portion and a left half portion in advance, and the right half portion and the left half portion are welded together in a container filled with a low specific gravity gas. By making the welded main cavity into a structure separated from the outside by shielding, the low specific gravity gas can be enclosed in the main cavity.

The method of movably attaching the rocking part to the lure body is not limited to the above-described embodiment. For example, the rocking section may be mounted to the lure body via a hinge. The rocking part may be attached to the lure body via a universal joint. After the lure is changed from the operating state to the stopped state, the oscillating portion may be attached to the lure body so that the oscillating portion can operate for a while with respect to the lure body.

The present invention has been described above by way of examples of the embodiments of the lure for fishing. Although not exemplified here, the present invention can also be applied to baits for aquatic animals other than fish, such as bait wood.

As described above, the lure according to the present invention can effectively lure fish by the operation of the rocking section. In this lure, the pressure of the main cavity can be reduced compared to the atmospheric pressure. Therefore, the rocking section can be operated for a longer time after the action of the lure is stopped. In the lure, after the action of the lure is stopped, fish-feeding fish can be effectively attracted. Based on this point, the superiority of the present invention is obvious.
