Description

  The present invention relates to the structure of a yaen used for squid fishing.

  In squid fishing, a fishing method using a hook called yaen (yaen fishing method) is known. A conventional Yaen structure is as shown in FIG.

  As shown in the figure, live bait fish 1 is used in the Yaen fishing method. The angler casts this bait fish 1 using rods and reels, and invites the squid 2 bite by swimming in the sea. When squid 2 bites into bait fish 1, yaen 3 is thrown. The yaen 3 is hooked on the fishing line 4 to which the bait fish 1 is attached and guided to the sea. The yaen 3 is slid to the position of the bait fish 1, and the hooks 5 and 6 provided at the tip of the yaen 3 are hooked on the squid 2. The yaen 3 includes a metal main body 7, the hooks 5 and 6 are attached to the front end of the main body 7, and a pair of fishing line guides 8 and 9 are provided at the center or rear end. . The fishing line guides 8 and 9 are hooked on the fishing line 4, so that the yaen 2 slides along the fishing line 3. A weight 10 is provided on the main body 7 so that the yaen 3 slides smoothly.

  By the way, in order for the angler to reliably take in the squid 2, it is necessary for the hooks 5 and 6 to be surely hooked on the squid 2. However, as shown in the figure, the yaen 3 generally reaches the squid 2. At the time, the distance d between the hooks 5 and 6 and the squid 2 tends to increase due to the angle of the fishing line 4 and other various factors, and this often causes the squid to escape. For this reason, various improvements have been attempted in the past in order to reduce the distance d (see, for example, Patent Documents 1 to 9).

JP 2002-320433 A Utility Model Registration No. 3082308 Japanese Patent Laid-Open No. 2005-110578 Japanese Patent No. 3580799 JP 2003-325086 A Utility Model Registration No. 3087326 JP 2003-245028 A JP 2003-23936 A JP 2002-51676 A

  Since the yaen 3 is generally formed in a straight line as shown in the figure, the distance d is increased. In actual fishing, the fisherman operates the fishing rod to loosen the tension of the fishing line 4 when it is determined that the yaen 3 has reached the position shown in FIG. When the fishing line 4 bends, the weight 10 rapidly sinks, and the yaen 3 rotates clockwise in the figure with the fishing line guide 8 as a fulcrum. As a result, the distance d between the hanging needles 5 and 6 and the squid 2 is reduced, and the yaen 3 is reliably caught on the squid 2. However, in order to operate the yaen 3 that has reached the vicinity of the squid 2 as described above, skill is required. Generally, the angler fails to operate the yaen 3 and causes the squid 2 to escape.

  For this reason, conventionally, the main body 7 is divided into two in the longitudinal direction, and the front part provided with the hanging needles 5 and 6 can be turned upward (toward the squid 2 side). Has been. By providing the front portion so as to be rotatable with respect to the rear portion, when the hooks 5 and 6 are hooked on the squid 2, even if the angle θ of the fishing line 4 with respect to the water surface is increased, 6 is hard to come off from the squid 2, and therefore the squid 2 is easily taken in. However, for the angler, the operation until the hooks 5 and 6 are hooked on the squid 2 is the same as before, and skill is required.

  The present invention has been made based on such a background, and is to provide a yaen that is surely caught by a hit squid.

  (1) In order to achieve the above object, the squid fishing yaen according to the present invention is provided on the rear main body formed in a linear shape and on the rear main body so as to protrude upward, and the fishing line extends along the longitudinal direction. The posture changes between the slidably inserted fishing line insertion portion, the lying posture extending in the longitudinal direction of the rear main body and the standing posture standing up with respect to the rear main body, and always becomes the lying posture by its own weight. A front body having an intermediate portion rotatably connected to a front end of the rear main body, a hook needle provided so as to protrude upward at the front end portion of the front main body, and a rear end of the front main body so as to protrude upward And a posture change support member that slides toward the tip of the fishing line along the fishing line and changes the front body to a standing posture by abutment of bait provided at the tip of the fishing line. .

  In actual squid fishing, a live bait (typically a horse mackerel) is connected to the tip of a fishing line, which is thrown into the sea to swim. When the squid bites into this bait, the angler throws in the squid fishing yaen. Specifically, the fishing line is inserted into the fishing line insertion part, and the yaen enters the sea along the fishing line. The yaen slides along the fishing line and reaches the bait position. Since the front body of the yaen is always lying down due to its own weight, the yaen that has entered the sea slides smoothly without getting caught in the fishing line and reaches the bait. When the yaen reaches the bait, the bait comes into contact with the posture change support member of the front main body, whereby the front main body is in the standing posture. That is, the front body is bent with respect to the rear body and jumps upward. Thereby, the hook provided in the front main body is surely hooked to the squid. Here, in the conventional yaen, when the angler pulls the fishing line, the yaen tends to rotate around the fishing line insertion portion and the hook is likely to come off the squid. However, in the yaen according to the present invention, when the fishing line is further pulled while the front body is bent upward and the hook is hooked on the squid, the bait relatively presses the posture change support member. Therefore, the front main body is bent further upward, and the hook needle is more reliably caught on the squid. Further, since the rear main body is connected to the middle portion of the front main body, the front main body changes its posture by utilizing the action of its own weight. Therefore, a weight or other means for increasing the weight of the yaen is not required to change the posture of the front main body, and as a result, a light weight design of the yaen is possible.

  (2) Here, it is preferable that the position of the intermediate portion of the front main body is set so that the front main body changes from a lying posture to a standing posture by a moment of 0.1 Ncm to 0.4 Ncm.

  In this configuration, the front body is always in the lying posture, but changes to the standing posture only when a small force is applied to the posture change support member. Therefore, when the yaen that has entered the sea reaches the bait and the bait comes into contact with the posture change support member, the front member jumps up and is caught by the squid.

  (3) It is preferable that a rotation restricting portion for restricting the standing angle within a certain range is further provided.

  This restricts the front body from jumping up extremely. Therefore, the hook can be reliably hooked to the squid and prevented from being easily detached from the squid.

  (4) A posture stabilizing member for stabilizing the posture of the main body after moving in water along the fishing line may be further provided.

  Yaen has a great resistance to seawater because it travels through the sea. If a strong turbulent flow is generated around the front body or the rear body traveling in the sea, the yaen may not be able to quickly reach the bait. In the present invention, since the posture stabilizing member is provided, the posture of the main body is stabilized after moving in water, and thus yaen can quickly reach the bait.

  (5) The rear main body may be formed so as to be bent in the vertical direction at the intermediate portion.

  When a fisherman winds a fishing line and brings a squid, the angle between the fishing line and the sea surface increases. For this reason, the yaen rotates around the fishing line insertion portion, and the yaen tends to come off the squid. However, in the present invention, the rear main body is bent upward, so that the hook provided on the front main body is prevented from coming off the squid.

  According to the present invention, when the squid fishing yaen reaches the squid, it immediately bends and the hook is caught on the squid, and the yaen once caught on the squid does not easily come off. Therefore, the angler can reliably capture the squid that has been hit.

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

<First Embodiment>

  FIG. 1 is a perspective view of a squid fishing yaen (hereinafter simply referred to as “yaen”) according to a first embodiment of the present invention.

  As shown in the figure, the yaen 20 includes a front main body 21 and a rear main body 22, and a front end portion 23 of the rear main body 22 is connected to an intermediate portion 24 of the front main body 21. The feature of the yaen 20 according to the present embodiment is that the front main body 21 and the rear main body 22 are connected as will be described later, so that the yaen 20 can be bent very easily. It is a point. In actual fishing, the yaen 20 is bent in the manner described later, so that it can be surely caught by the squid.

  The rear main body 22 includes a main shaft portion 25, a first fishing line insertion portion 26, and a second fishing line insertion portion 27.

  The main shaft portion 25 is made of, for example, linear stainless steel. The wire diameter of this stainless steel can be set to about 0.5 mm to 2.0 mm. But the material which comprises the main-shaft part 25 is not limited to stainless steel, Resin can be employ | adopted besides the various metal to which the rust prevention process was given. The front end portion 23 of the rear main body 22, that is, the front end portion 23 of the main shaft portion 25 is bent in a direction orthogonal to the longitudinal direction of the main shaft portion 25 as shown in FIG. The tip 23 is fitted into a support pipe 28 described later.

  In the present embodiment, a weight 29 is provided on the main shaft portion 25. The weight 29 is made of lead and is formed in a spindle shape as shown in FIG. The material constituting the weight 29 may be tungsten, brass, or another metal having a large specific gravity instead of lead. The weight 29 is provided with a through hole (not shown) extending in the axial direction. The main shaft portion 25 is inserted through the through-hole, whereby the weight 29 is slidable in the longitudinal direction along the main shaft portion 25. However, a slide restricting portion 30 is provided behind the main shaft portion 25. The slide restricting portion 30 is formed in a columnar shape, and is fixed so that the center thereof coincides with the center of the main shaft portion 25. The slide restricting portion 30 is disposed in front of the weight 29, and the outer dimension of the slide restricting portion 30 is set larger than the inner diameter dimension of the through hole provided in the weight 29. Therefore, the weight 29 cannot be inserted through the slide restricting portion 30 and can slide only between the rear end of the main shaft portion 25.

  Further, a ring member 31 (rotation restricting portion) is provided in front of the main shaft portion 25. This ring member 31 is also made of the same material as the main shaft portion 25. The ring member 31 is formed in an elongated ring extending in the vertical direction as shown in FIG. The front main body 21 is inserted through the ring member 31. The operational effects of providing the ring member 31 will be described later.

  The first fishing line insertion portion 26 is integrally formed continuously with the rear end of the main shaft portion 25. Therefore, the first fishing line insertion portion 26 is also made of the same material as the main shaft portion 25. The first fishing line insertion portion 26 includes an extending portion 32 that is continuous with the main shaft portion 25 and extends upward, and a line engaging portion 33 provided at the tip of the extending portion 32. The extended portion 32 is substantially orthogonal to the main shaft portion 25, and the thread engaging portion 33 is formed by winding the tip end portion of the extended portion 32 in an annular shape. Therefore, the fishing line 34 can easily enter the line engaging part 33 by being wound around the line engaging part 33 along the winding direction of the line engaging part 33 and the winding direction. As long as it is not wound in the opposite direction, it will not be easily detached from the thread engaging portion 33. When the fishing line 34 is inserted into the line engaging portion 33, the fishing line 34 can slide smoothly in the longitudinal direction with respect to the line engaging portion 33.

  The second fishing line insertion portion 27 includes a roller support portion 35 and a guide portion 36. The guide portion 36 is made of the same material as that of the main shaft portion 25, and includes a first leg portion 37, a guide ring 38, and a second leg portion 39. The first leg portion 37 and the guide ring 38 are integrally formed, and are configured by bending linear stainless steel. Specifically, the guide ring 38 is formed by continuously winding the stainless steel in an annular shape above the first leg portion 37 formed in an approximately L shape. Therefore, the fishing line 34 can easily enter the guide ring 38 by being wound around the guide ring 38 along the winding direction of the guide ring 38 and is wound in the direction opposite to the winding direction. Unless it is done, the guide ring 38 is not easily detached. When the fishing line 34 is inserted into the guide ring 38, the fishing line 34 can smoothly slide in the longitudinal direction with respect to the guide ring 38. Similarly to the first leg portion 37, the second leg portion 39 is made of linear stainless steel, and connects the main shaft portion 25 and the vicinity of the guide ring 38.

  FIG. 2 is a partially enlarged perspective view of FIG. 1 and shows the structure of the roller support portion 35 in detail. 3 is a view taken in the direction of the arrow A in FIG. 2, and FIG. 4 is a sectional view taken along the line IV-IV in FIG.

  The roller support part 35 has a pulley mechanism 41, as shown in FIG. The pulley mechanism 41 includes a pulley 44 and a support frame 46 that supports the pulley 44 via a support mechanism 45 described later. The support frame 46 includes a frame main body 47 and leg portions 48. The leg portion 48 is made of the same material as that of the main shaft portion 25. The leg portion 48 is formed in an approximately L shape, and one end portion is fixed to the main shaft portion 25. In the present embodiment, as shown in the figure, the leg portion 48 is caulked to the main shaft portion 25 using a caulking member 49, for example. The caulking member 49 fixes the leg portion 48 to the main shaft portion 25 together with the first leg portion 37 of the guide portion 36. The other end of the leg 48 is fixed to the frame body 47. The fixing structure will be described later.

  The frame main body 47 is made of, for example, stainless steel (SUS304) or resin. As shown in FIG. 3, the frame main body 47 has a main body upper part 50 and a main body lower part 51, which are integrally formed. As shown in FIGS. 3 and 4, the lower part 51 of the main body has a hollow structure on the right side in the drawing, and a solid structure on the left side in the drawing. The other end portion of the leg portion 48 is inserted into the main body lower portion 51 from the right side of the main body lower portion 51 in the drawing and penetrates the solid portion of the main body lower portion 51. Thereby, the other end portion of the leg portion 38 is fixed to the main body lower portion 51.

  The main body upper part 50 is formed to have a substantially U-shaped cross section, and has a pair of side plates 52 and 53. The pulley 44 is supported by the side plate 53. The side plate 52 is set to be smaller in height than the side plate 53. As shown in FIG. 3, the upper edge of the side plate 52 is formed in an arc shape along the peripheral surface of the pulley 44 supported by the side plate 53. A gap 54 is formed between the upper edge of the side plate 52 and the peripheral surface of the pulley 44. The gap 54 is for inserting the fishing line 34 as will be described later, and the size thereof is appropriately set in accordance with the thickness of the fishing line 34.

  Further, as shown in FIG. 4, a C surface 55 is formed on the upper edge of the side plate 52. Thereby, the upper edge of the side plate 52 is an inclined surface that opens toward the outside of the side plate 52. Further, the outer surface 56 of the side plate 52 is on the same plane as the outer surface 57 of the pulley 44. Functions and effects of the function of the C surface 55 and the fact that the side plate 42 and the pulley 44 are disposed on the same surface will be described later.

  The side plate 53 is disposed to face the side plate 52 along the axial direction of the pulley 44, and is disposed on the outer surface 58 side of the pulley 44 as shown in FIG. The side plate 53 is provided with a pin insertion hole 59. In the pin insertion hole 59, a support pin 60 described later is inserted and supported.

  The pulley 44 is made of, for example, polyacetal (POM) or the like. As shown in FIG. 4, the pulley 44 is formed with a substantially V-shaped groove 61. When the yaen 30 is engaged with the fishing line 34, the fishing line 34 is fitted into the groove 61. Further, a C surface 68 is formed on the peripheral surface of the pulley 44. The function of the C surface 58 will be described later.

  The pulley 44 is supported on the frame body 47 by a support mechanism 45. The support mechanism 45 includes the support pin 60, the bush 62, the bearing 63, and the spacer 64.

  The bearing 63 is a ball bearing in this embodiment. As shown in FIG. 4, the outer ring of the bearing 63 is fitted inside the pulley 44. The bushing 62 is made of, for example, stainless steel (SUS304). The bush 62 is formed in a cylindrical shape and is fitted inside the inner ring of the bearing 63. A female thread is formed on the inner surface of the bush 62. The spacer 64 is made of, for example, stainless steel (SUS304). The spacer 64 is formed in a ring shape, and is interposed between the side plate 53 of the frame body 47 and the bearing 63 to position the bearing 63. The support pin 60 is made of, for example, stainless steel (SUS304). A male screw is formed on the shaft portion of the support pin 60. The support pin 60 is inserted from the outside of the side plate 53 into the pin insertion hole 59 and penetrates the spacer 64 and the bushing 62. The male screw of the support pin 60 and the female screw of the bush 62 are engaged with each other. When the support pin 60 is tightened, the pulley 44 is supported in a cantilever manner together with the bearing 63, the bush 62, and the spacer 64. By supporting the pulley 44 in this way, the pulley 44 is rotatable about the support pin 60.

  As shown in FIG. 1, the front main body 21 is made of, for example, linear stainless steel. The wire diameter of this stainless steel can be set to about 0.5 mm to 2.0 mm. But the material which comprises the front main body 21 is not limited to stainless steel, Resin can be employ | adopted besides the various metal in which the antirust process was performed. The front main body 21 includes a main shaft portion 70 that extends straight and a bent portion 71 (posture change support member) that is continuous with the rear end of the main shaft portion 70 and extends upward. In the present embodiment, the main shaft portion 70 and the bent portion 71 are configured by bending a single stainless steel, but both are configured as separate members and may be fixed by known fixing means. Of course it is good. More specifically, the rear end portion of the main shaft portion 70 is formed with a bulging portion 72 bulging in a direction orthogonal to the longitudinal direction of the main shaft portion 70 (the front direction in the figure). An intersecting portion 73 that is continuous to 72 and extends in the direction of the hand so as to be orthogonal to the main shaft portion 70 is formed. The bent portion 71 is formed continuously with the intersecting portion 73.

  The bent portion 71 includes a leg portion 74 extending upward and a thread engaging portion 75 provided at the tip of the leg portion 74. The thread engaging portion 75 is formed by winding the upper portion of the leg portion 74 in an annular shape. Accordingly, the fishing line 34 can easily enter the line engaging part 75 by being wound around the line engaging part 75 along the winding direction of the line engaging part 75 and the winding direction. As long as it is not wound in the opposite direction, it will not be easily detached from the thread engaging portion 75. When the fishing line 34 is inserted into the line engaging portion 75, the fishing line 34 can slide smoothly in the longitudinal direction with respect to the line engaging portion 75.

  The support pipe 28 is attached to the intermediate portion 24 of the front main body 21. As described above, the front end portion 23 of the rear main body 22 is inserted and supported by the support pipe 28, whereby the front main body 21 is bent with respect to the rear main body 22. Since the support pipe 28 is located at the intermediate portion 24, the front main body 12 is supported by the rear main body 22 at a position slightly behind the center of gravity. Specifically, if the total length of the front main body 21 is L, the support pipe 28 is attached at a position of 0.6 L to 0.7 L from the tip. Thereby, the front main body 21 always rotates in the direction of the arrow 76 in FIG. When the front main body 21 rotates in the direction of the arrow 76, the intersecting portion 73 of the front main body 21 comes into contact with the main shaft portion 25 of the rear main body 22, and the front main body 21 is always in the above-described lying posture. In the present embodiment, the intersection 73 is brought into contact with the rear main body 22 to restrict the rotation of the front main body 21 in the direction of the arrow 76. Various other means may be employed as means for restricting the rotation of the front main body 21 in order to maintain it.

  As described above, the front main body 21 is supported by the rear main body 22 in the vicinity of the center of gravity. Therefore, even when a small moment about the support pipe 28 acts on the front main body 21, the front main body 21 Immediately it rotates in the direction opposite to the arrow 76 and changes to the posture (standing posture) as shown in FIG. However, if the action of the moment centering on the support pipe 28 is lost, the front main body 21 returns to the lying posture again. Since the support pipe 28 is located at the intermediate portion 24, the moment required for the front main body 21 to change from the lying posture to the standing posture is about 0.2 Ncm. However, this moment can be set to 0.1 Ncm to 0.4 Ncm by changing the position of the intermediate portion 24. However, it is more desirable that the moment is set to 0.3 Ncm or less.

  Hanging needles 77 to 79 are provided at the distal end portion of the front main body 21, that is, the distal end portion of the main shaft portion 70. In the present embodiment, three hanging needles 77 to 79 are provided, but this quantity is not particularly limited. Each hanging needle 77 to 79 is disposed so as to protrude upward. Thereby, the hanging needles 77 to 79 are easily caught on the squid. In general, when the number of hooks increases, the support pipe 28 is attached to the front of the intermediate portion 24, and when the number of hooks decreases, the support pipe 28 becomes lower than the intermediate portion 24. As described above, the front main body 21 is set to change to a standing posture by a moment of about 0.2 Ncm by adjusting the mounting position of the support pipe 28 as described above. However, as described above, the front main body 21 can be set so that its posture is changed by a moment of 0.1 Ncm to 0.4 Ncm. In the embodiment, it is attached to a region which is 10 mm or more rearward from the hanging needle 79) and 10 mm or more forward from the intersecting portion 73 which is the base end of the bent portion 71. In other words, by disposing the support pipe 28 in the region, a moment of 0.4 Ncm or less acts on the front main body 21, and the front main body 21 can change to a standing posture.

  The yaen 20 according to the present embodiment is used as follows in actual fishing for squid fishing. FIG.5 and FIG.6 is a schematic diagram which shows the usage point of the yaen 20 which concerns on this embodiment.

  First, the angler attaches the horse mackerel 80 alive as a bait to the tip of the fishing line 34, throws it into the sea and swims (see FIG. 1). When the squid bites into the horse mackerel, as shown in FIG. 5, the fisherman inserts the fishing line 34 into the first fishing line insertion part 26 and the second fishing line insertion part 27 of the yaen 20 and the thread engagement part of the front main body 21. The fishing line 34 is also inserted through 75. As a result, the yaen 20 enters the sea along the fishing line 34 and reaches the position of the horse mackerel 80 (see FIG. 6). Since the front main body 21 of the yaen 20 is always in a lying posture, the yaen 20 that has entered the sea slides smoothly without reaching the fishing line 34 as shown in FIG.

  As shown in FIG. 6, when the yam 20 reaches the aji 80, the aji 80 relatively abuts against the bent portion 71 of the front main body 21. As described above, when a moment is applied to the front main body 21 around the support pipe 28 (see FIG. 1) disposed in the intermediate portion 24, the front body 21 immediately stands up even if the moment is extremely small. Therefore, when the horse mackerel 80 comes into contact with the bent portion 71, the front main body 21 quickly changes to a standing posture. That is, the front main body 21 is bent with respect to the rear main body 22, and jumps upward as shown in FIG. As a result, the hanging needles 77 to 79 are reliably caught on the squid 81.

  In the conventional yaen, when the angler operates the fishing rod in this state and further pulls the fishing line 34, the yaen 20 rotates around the second fishing line insertion portion 27 and the hooks 77 to 79 are detached from the squid 81. Tended to end up. However, in the yaen 20 according to the present embodiment, even if the fishing line 34 is pulled when the front main body 21 is in the standing posture, the horse mackerel 80 relatively presses the bent portion 71. 21 maintains the standing posture. That is, the front main body 21 is bent further upward, and the hooks 77 to 79 are more reliably hooked to the squid 81. As described above, the yaen 20 according to the present embodiment is surely caught on the squid 81 and is not easily detached once it is caught on the squid 81. Therefore, the angler can reliably capture the squid 81 that has been hit. In addition, in the yaen 20 according to the present embodiment, the front main body 21 can maintain a lying posture using the action of its own weight, and can quickly change to a standing posture. A weight or the like that supports the posture change of 21 is unnecessary. Therefore, the yaen 20 can be designed to be lightweight. The lightened yaen 20 does not give the squid 81 a sense of incongruity and has an advantage that it is difficult to carry out so-called rooting.

  In particular, in the present embodiment, the front main body 21 changes to a standing posture when a moment of 0.4 Ncm or less is applied. Therefore, when the yaen 20 that has entered the sea reaches the horse mackerel 80, the front body 21 jumps up instantaneously to the squid 81. Get caught. Thereby, the yaen 20 is more reliably caught on the squid 81, and there is an advantage that the angler can take in the squid 81 with a higher probability.

  In the present embodiment, the ring member 31 is provided on the rear main body 22. Since the main shaft portion 70 of the front main body 21 is inserted through the ring member 31, the main shaft portion 70 of the front main body 21 contacts the lower end of the ring member 31 when the front main body 21 changes to a standing posture. Therefore, even when the front main body 21 is in the standing posture, the jumping up extremely as shown in FIG. 6 is restricted. Therefore, there is an advantage that the hook needles 77 to 79 can be reliably hooked to the squid 81, and the hook needles 77 to 79 are more reliably prevented from coming off from the squid 81.

  In the present embodiment, when the yaen 20 slides along the fishing line 34, the fishing line 34 is wound around the pulley 44 and supported by the fishing line 34 via the pulley 44. That is, there is an advantage that the fishing line 34 and the second fishing line insertion portion 27 are in rolling contact with each other, and the yaen 20 is guided very smoothly into the sea. Further, since the second fishing line insertion portion 27 includes the guide ring 38, the fishing line 34 reliably engages with the pulley 34 and does not easily come off. Therefore, in actual fishing, even when an unscheduled external force is applied to the yaen 20 due to wind, waves, or the like, the yaen 20 does not fall off the fishing line 34. Moreover, since the guide ring 38 extends in the radial direction of the pulley 44 (see FIG. 1), even when the fishing line 34 is displaced in the radial direction of the pulley 44 when the yaen 20 is guided into the sea. That is, even when the yaen 20 is inclined downward in FIG. 5, the fishing line 34 is prevented from being detached from the pulley 44.

  Further, as shown in FIG. 4, the pulley mechanism 41 that supports the pulley 44 rotatably supports the pulley 44 via a bearing 63, so that the pulley 44 can rotate very smoothly. Thereby, the yaen 20 can move more smoothly along the fishing line 34, and even if the distance to the hit squid 81 is large, the yaen 20 can surely reach the squid 81. There are advantages. In particular, the bearing 63 is preferably an anti-last bearing. Anti-last bearings have extremely high corrosion resistance against seawater and the like. Therefore, the rotation performance of the pulley 44 does not deteriorate due to corrosion of the bearing, and can be smoothly rotated over a long period. In this embodiment, a ball bearing is employed as the bearing 63, but the present invention is not limited to this, and a slide bearing or the like may be employed.

  Further, when the fishing line 34 is engaged with the pulley 44, the fishing line 34 is introduced into the groove 61 of the pulley 44 from the gap 54 between the pulley 44 and the support frame 46. As shown in FIG. 3, the frame main body 47 of the support frame 46 is curved along the peripheral surface of the pulley 44. However, since the C surface 55 is formed on the support frame 46, the fishing line 34 is It is easily introduced into the pulley 34 from the gap 44. Moreover, since the frame main body 47 is curved as described above and is disposed opposite to the peripheral surface of the pulley 44, the fishing line 34 can be easily detached from the pulley 34 once introduced into the groove 61 of the pulley 44. There is no. In addition, in the present embodiment, since the C surface 68 (see FIG. 4) is provided on the peripheral surface of the pulley 44, the fishing line 34 is more easily inserted into the pulley 44 and further detached from the pulley 44. It becomes difficult.

<Second Embodiment>

  Next, a second embodiment of the present invention will be described.

  FIG. 7 is a perspective view of a squid fishing yaen according to the second embodiment of the present invention.

  The difference between the yaen 85 according to the present embodiment and the yaen 20 according to the first embodiment is that a posture stabilizing member 86 for stabilizing the posture when the yaen 85 travels in the sea is provided. The rear main body 22 is divided into two in the longitudinal direction, and can be bent in the vertical direction. Other configurations are the same as those of the yaen 20 described above.

  The posture stabilizing member 86 is made of a highly corrosion-resistant metal or resin such as stainless steel. In the present embodiment, the posture stabilizing member 86 is provided on the rear main body 22. Specifically, the posture stabilizing member 86 is formed in a triangular thin plate shape, and is fitted and fixed between the first leg portion 37 and the second leg portion 39 of the guide portion 36.

  The rear main body 22 is divided into two at its substantially central portion (intermediate portion), and has a front portion 87 and a rear portion 88. The rear end portion 89 of the front portion 87 is bent in a direction orthogonal to the longitudinal direction of the main shaft portion 25 as with the tip end portion 23. A support pipe 90 is provided at a predetermined position of the rear portion 88. The support pipe 90 has the same configuration as the support pipe 28 provided in the front main body 21. A rear end portion 89 of the front portion 87 is fitted into the support pipe 90 so as to be rotatable. Therefore, the rear portion 88 rotates in the direction of the arrow 91 with respect to the front portion 87 and can be bent in the vertical direction. However, since the weight 29 is provided at the rear portion 88, the rear portion 88 always rotates clockwise in FIG. A contact portion 92 is provided at the tip of the rear portion 88, and the contact portion 92 contacts the front portion 87 from below by rotating the rear portion 88 clockwise. Thereby, the rear part 88 becomes a straight attitude | position with respect to the front part 87, as FIG. 7 shows. In the present embodiment, the rear main body 22 is divided into two at a substantially central portion, but the division position may be set to another position. In that case, even if the weight 29 is not provided, the dividing position is preferably set so that the rear portion 88 is always in a straight posture with respect to the front portion 87 by the action of its own weight.

  Since the yam 85 according to the present embodiment is provided with the posture stabilizing member 86, the posture in the sea is stabilized. When the Yaen 85 is thrown into the sea, it proceeds through the sea until it reaches the horse mackerel 80, and the resistance of the seawater is large. If a strong turbulent flow is generated around the bean 85 that travels under the sea, for example, around the front main body 21 or the rear main body 22, the yaen 85 may be decelerated and cannot reach the horse 80 quickly. However, in the yaen 85 according to the present embodiment, the seawater around the yaen 85 is rectified by the posture stabilizing member 86. Particularly, since the posture stabilizing member 86 is provided in the rear main body 22, the posture of the rear main body 22 moving in the sea is stabilized, and the yam 85 quickly reaches the horse mackerel 80 and is caught by the squid 81. In this embodiment, the posture stabilizing member 86 is provided on the rear main body 22, but may be provided on the front main body 21. In short, it is only necessary that the posture stabilizing member 86 is disposed at a position where the seawater around the yaen 85 can be rectified and the posture of the yaen 85 can be stabilized when the yaen 85 travels in the sea.

  FIG. 8 is a schematic diagram illustrating a usage state of the yaen 85 according to the present embodiment.

  In this yaen 85, the rear main body 22 is divided into two, and the rear portion 88 of the rear main body 22 can be bent in the vertical direction. The angler throws the yaen 85 into the sea and winds the fishing line 34 using a reel, thereby bringing the squid 81 closer to the front side. In this case, as shown in the figure, the angle θ between the fishing line 34 and the sea surface increases. For this reason, if the rear main body 22 is not divided | segmented, it will become easy for the yaen 85 to rotate counterclockwise with the pool 44 as a fulcrum. That is, the hanging needles 77 to 79 are easily detached from the squid 81. However, in the yam 85 according to the present embodiment, as the angle θ increases, the rear portion 88 can be bent upward as shown in the figure, and as a result, the hanging needle 77 once caught on the squid 81. There is an advantage that .about.79 is difficult to be removed from the squid 81.

  FIG. 9 is a perspective view of a yaen 100 according to a modification of each of the above embodiments.

  In each of the embodiments described above, the moment for changing the posture of the front main body 21 from the lying posture to the standing posture is adjusted by changing the mounting position of the support pipe 28. However, the adjustment of the moment may be performed by providing a balance weight 93 on the main shaft portion 70 of the front main body 21, as shown in the figure, in addition to the adjustment of the mounting position of the support pipe 28. Specifically, the balance weight 93 is made of linear stainless steel like the main shaft portion 70 of the front main body 21, and is connected to the intersecting portion 73, along the axial direction of the main shaft portion 70. It extends backward. By setting the balance weight 93 to a predetermined length, the moment is adjusted to a desired value. The balance weight 93 may be provided so as to be extendable and contractable in the axial direction of the main shaft portion 70. As a structure for expanding and contracting the balance weight 93, a piston / cylinder structure may be employed. In this case, the angler can freely adjust the moment by adjusting the length of the balance weight 93 in actual fishing.

  In each of the above embodiments, the support pipe 28 is attached to the upper side of the front main body 21, but the support pipe 28 may be attached to the lower side of the front main body 21 as shown in FIG. Of course. As shown in FIGS. 1 and 7, the distal end portion 23 of the main shaft portion 25 of the rear main body 22 is bent to the right with respect to the longitudinal direction of the main shaft portion 25. May be bent to the left with respect to the longitudinal direction of the main shaft portion 25.
