Description

  The present invention relates to a structure of a sea urchin used for fishing.

  There is a fishing genre called “Uki Fishing”. FIG. 22 is a schematic diagram showing a common fishing mechanism. In uki fishing, a through-type uki is often used (see, for example, Patent Document 1 to Patent Document 6).

  The hollow type Uki 1 is generally formed in a substantially spindle shape. A line insertion hole is provided along the central axis of the ground 1. The line 3 guided along the fishing rod 2 is inserted into the line insertion hole of the ground 1. Harris 5 is connected to the tip of the line 3. The line 3 and the Harris 5 may be directly connected to each other, but in the same figure, a connecting tool 4 called “Salkan” is interposed therebetween. A needle 6 is tied to the tip of Harris 5. At a predetermined position of the line 3, a snow stopper 7 is attached. The needle 6, the Harris 5, the line 3 and the like are submerged in water by their own weight. The Uki stop 7 approaches the Uki 1 relatively. When the uki stop 7 abuts on the uki 1, the relative movement of the uki 1 with respect to the line 3 is restricted, and the position of the needle 6 in water (commonly referred to as “tana”) is set.

  By the way, in actual fishing, there are cases where the weight of the ground (that is, the residual buoyancy in water) and the size of the outer shape are changed according to the conditions of the fishing ground (wind, waves, tides, etc.). That is, the uki 1 may be replaced with another type of uki (a uki with different size and buoyancy). However, since the uki 1 is of the middle type, the fisherman has to cut the line 3 once when trying to exchange this kind of uki 1, and the line 3 is again connected to the exchanged uki. Must be inserted. Therefore, there is a problem that the exchanging work of the sea urchin is complicated for the angler. This problem has been particularly serious in competitions and the like that compete for fishing results within a predetermined time. Conventionally, in order to solve this problem, proposals have been made to detachably attach to the line without cutting the line (see Patent Documents 7 to 11).

JP 2001-309739 A JP 2000-287593 A JP 2000-125729 A JP 2000-60383 A Japanese Patent Laid-Open No. 11-18647 JP-A-2005-151978 JP-A-11-56186 JP-A-9-9836 Japanese Utility Model Publication No. 6-55370 JP-A-7-255340 JP 2002-223682 A

  The uki, which can be exchanged without cutting the line, generally includes a uki body and a fitting shaft fitted thereto. A fitting shaft consists of a hollow pipe, and a fishing line is inserted in this. On the other hand, the main body has a fitting hole penetrating in the axial direction, and the fitting shaft is fitted into the fitting hole. Moreover, the main body is provided with a slit extending in the axial direction, and this slit is cut in the radial direction of the main body (a direction orthogonal to the axial direction) and communicates with the fitting hole (Patent Document) 7 and Patent Documents 8 to 11).

  However, the conventional uki cannot be said to be easy to attach and detach the uki body in actual fishing. Specifically, in the Uki disclosed in the above-mentioned Patent Document 7, the angler rotates the Uki main body (2) while holding the rod (12) of the mandrel (1) between the tips of the fingers. ) And the mandrel (1) must be unscrewed, and the angler (12) is so small that the angler must pick up the nail (12) with his claws. It is very difficult to attach and detach 2) to the mandrel (1). Further, in the Uki disclosed in Patent Documents 8 to 11, the fitting shaft is almost completely embedded in the Uki main body, so that it is very difficult for the angler to attach and detach the fitting shaft. In addition, since these fitting shafts are also provided with slits, the fishing line may bite between the fitting shaft and the main body and may be damaged.

  Accordingly, an object of the present invention is to provide a threading type fishing lure that can be easily and quickly replaced without cutting the fishing line.

  (1) In order to achieve the above-mentioned object, the fishing lure according to the present invention has an outer peripheral surface, a through hole formed along the axial direction so as to penetrate the center, and extends in the axial direction and has a diameter from the outer peripheral surface. A main body having a slit cut so as to communicate with the through-hole along the direction, and a fishing line insertion hole formed along the axial direction so as to penetrate the center, and the through-hole of the main body A cylindrical fitting shaft inserted and removed from above, an outer surface, an axial hole formed along the axial direction so as to penetrate the center, and the axial hole extending in the axial direction and radially from the outer surface A slit cut so as to communicate with the cylindrical fitting shaft, and detachably engages with a lower end portion of the cylindrical fitting shaft inserted into the through-hole so that the cylindrical fitting shaft falls off from the main body. An annular fixing member for preventing this, the annular fixing member is It also serves as a weight that sets the buoyancy of the body.

  The angler inserts the fishing line into the fishing line insertion hole of the cylindrical fitting shaft. The cylindrical fitting shaft is always engaged with the fishing line and is slidable along the fishing line. In this state, the fishing line positioned below the cylindrical fitting shaft is inserted into the slit from the outer peripheral surface of the main body. Since the slit reaches the through hole of the main body, the fishing line is disposed in the through hole through the slit. The angler inserts the cylindrical fitting shaft into the through hole from above the base body. As a result, the tubular fitting shaft is fitted into the through hole, and as a result, the fishing line is disposed in the through hole of the main body in a state surrounded by the tubular fitting shaft.

  Then, the angler engages the annular fixing member with the cylindrical fitting shaft. Specifically, the angler inserts the fishing line positioned below the cylindrical fitting shaft into the slit from the outer surface of the annular fixing member. Since the slit reaches the shaft hole of the annular fixing member, the fishing line is disposed in the shaft hole through the slit. The angler engages the annular fixing member with the lower end portion of the cylindrical fitting shaft. Thereby, the cylindrical fitting shaft inserted into the main body is prevented from falling off from the main body. That is, the cylindrical fitting shaft is positioned in the through hole and cannot be detached from the base body. Since the fishing line is inserted through the cylindrical fitting shaft positioned on the main body, the main body is attached to the fishing line together with the cylindrical fitting shaft and freely slides along the fishing line. be able to.

  Since the annular fixing member also serves as a weight, the buoyancy of the main body is determined by mounting the annular fixing member. Moreover, since this annular fixing member is attached to the lower end portion of the cylindrical fitting shaft, it is disposed below the main body. Therefore, the center of gravity of the main body is set at a low position, and the fishing base is easily stabilized in water.

  Moreover, the angler can remove the said annular fixing member from the said cylindrical fitting shaft, and can make it detach | leave from the said fishing line. Furthermore, the angler can pull out the cylindrical fitting shaft from the main body and detach the main body from the fishing line. That is, the main body is removed from the fishing line without cutting the fishing line.

  (2) It is preferable that a male screw is formed at a lower end portion of the cylindrical fitting shaft, and the annular fixing member is constituted by a nut that is screwed to the male screw and is pressure-bonded to the main body.

  In this configuration, the angler can easily engage the nut with the cylindrical fitting shaft by simply screwing the nut into the lower end portion of the cylindrical fitting shaft. That is, the work of attaching or removing the annular fixing member to the cylindrical fitting shaft is simple. Therefore, the angler can easily perform the work of attaching / detaching the cylindrical fitting shaft to / from the main body, and thus can quickly perform the replacement work of the main body.

  (3) When the annular fixing member is engaged with the cylindrical fitting shaft, a mounting portion having a flat surface on which the annular fixing member is stably brought into contact is provided at the lower portion of the main body. It is preferable.

  By providing the mounting portion described above, the annular fixing member is stabilized when and after the annular fixing member is engaged with the cylindrical fitting shaft. Therefore, the angler can more easily perform the operation of engaging the annular fixing member with the cylindrical fitting shaft.

  (4) An engagement portion is provided on the cylindrical fitting shaft, and an engagement portion that engages with the engagement portion is provided on the Uki main body. The engagement portion and the engagement portion are: It is preferable to constitute a rotation restricting means for restricting rotation about the axial direction of the cylindrical fitting shaft with respect to the main body.

  In this configuration, when the cylindrical fitting shaft is inserted into the Uki main body, the engaging portion and the engaged portion are engaged, and the cylindrical fitting shaft rotates with respect to the Uki main body. To be regulated. Therefore, the operation of engaging the annular fixing member with the lower end portion of the cylindrical fitting shaft is further facilitated. In particular, when the annular fixing member is screwed into the cylindrical fitting shaft, the cylindrical fitting shaft is prevented from rotating together with the tubular fixing member, and it is extremely difficult for the angler to mount the cylindrical fitting shaft on the main body. It will be easy.

  (5) It is preferable that a plurality of annular fixing members having different weights are provided.

  In this configuration, one annular fixing member attached to the cylindrical fitting shaft can be replaced with another annular fixing member. Thereby, since the weight of the whole fishing uki changes, the angler can adjust the residual buoyancy of the fishing uki intentionally. As a result, the stability of the fishing ground in water is further improved.

  (6) A fishing ground for achieving the above object may have the following structure. That is, the outer peripheral surface, a through hole formed along the axial direction so as to penetrate the center, and a slit that extends in the axial direction and is cut from the outer peripheral surface so as to communicate with the through hole along the radial direction. And a fishing line insertion hole formed along the axial direction so as to pass through the center, a cylindrical fitting shaft that is inserted into and removed from the through hole of the above-described main body, an outer surface, and a center. An axial hole formed along the axial direction so as to penetrate, and a slit which extends in the axial direction and is cut from the outer surface so as to communicate with the axial hole along the radial direction. An annular fixing member that detachably engages with the upper end portion of the inserted cylindrical fitting shaft to prevent the cylindrical fitting shaft from falling off the main body may be provided.

  The angler inserts the fishing line into the fishing line insertion hole of the cylindrical fitting shaft. The cylindrical fitting shaft is always engaged with the fishing line and is slidable along the fishing line. In this state, the fishing line positioned above the cylindrical fitting shaft is inserted into the slit from the outer peripheral surface of the main body. Since the slit reaches the through hole of the main body, the fishing line is disposed in the through hole through the slit. The angler inserts the cylindrical fitting shaft into the through hole from below the main body. As a result, the tubular fitting shaft is fitted into the through hole, and as a result, the fishing line is disposed in the through hole of the main body in a state surrounded by the tubular fitting shaft.

  Then, the angler engages the annular fixing member with the cylindrical fitting shaft. Specifically, the angler inserts the fishing line positioned above the cylindrical fitting shaft into the slit from the outer surface of the annular fixing member. Since the slit reaches the shaft hole of the annular fixing member, the fishing line is disposed in the shaft hole through the slit. The angler engages the annular fixing member with the upper end portion of the cylindrical fitting shaft. Thereby, the cylindrical fitting shaft inserted into the main body is prevented from falling off from the main body. That is, the cylindrical fitting shaft is positioned in the through hole and cannot be detached from the base body. Since the fishing line is inserted through the cylindrical fitting shaft positioned on the main body, the main body is attached to the fishing line together with the cylindrical fitting shaft and freely slides along the fishing line. be able to.

  Moreover, the angler can remove the said annular fixing member from the said cylindrical fitting shaft, and can make it detach | leave from the said fishing line. Furthermore, the angler can pull out the cylindrical fitting shaft from the main body and detach the main body from the fishing line. That is, the main body is removed from the fishing line without cutting the fishing line.

  (7) It is preferable that a male screw is formed at an upper end portion of the cylindrical fitting shaft, and the annular fixing member is constituted by a nut screwed with the male screw.

  In this configuration, the angler can easily engage the nut with the cylindrical fitting shaft by simply screwing the nut into the upper end portion of the cylindrical fitting shaft, and the removal work is also easy. Therefore, the angler can easily perform the work of attaching / detaching the cylindrical fitting shaft to / from the main body, and thus can quickly perform the replacement work of the main body.

  (8) When the annular fixing member is engaged with the cylindrical fitting shaft, a mounting portion having a flat surface on which the annular fixing member is mounted is provided on the upper part of the main body. preferable.

  By providing the mounting portion described above, the annular fixing member is stabilized when and after the annular fixing member is engaged with the cylindrical fitting shaft. Therefore, the angler can more easily perform the operation of engaging the annular fixing member with the cylindrical fitting shaft.

  (9) An engagement portion may be provided on the cylindrical fitting shaft, and an engaged portion that engages with the engagement portion may be provided on the base body. In this case, the engaging part and the engaged part constitute rotation restricting means for restricting rotation about the axial direction of the cylindrical fitting shaft with respect to the base body.

  In this configuration, when the cylindrical fitting shaft is inserted into the Uki main body, the engaging portion and the engaged portion are engaged, and the cylindrical fitting shaft rotates with respect to the Uki main body. To be regulated. Therefore, the operation of engaging the annular fixing member with the upper end portion of the cylindrical fitting shaft is facilitated. In particular, when the annular fixing member is screwed into the tubular fitting shaft, the tubular fitting shaft is prevented from rotating together with the tubular fixing member, and the work of attaching the tubular fitting shaft to the main body for the angler is further performed. It will be easy.

  (10) It is preferable that a weight is provided at the lower end of the above-mentioned main body, and a plurality of annular fixing members having different weights are provided.

  In this configuration, one annular fixing member attached to the cylindrical fitting shaft can be replaced with another annular fixing member. Thereby, since the weight of the whole fishing uki changes, the angler can adjust the residual buoyancy of the fishing uki intentionally. In addition, since the annular fixing member is attached to the upper end portion of the cylindrical fitting shaft, the position of the center of gravity of the fishing ground is brought closer to the center. Therefore, especially when the residual buoyancy of the fishing uki is set to almost zero, the center of gravity of the fishing uki can be set to the center of the fishing uki. Thereby, the stability in the water of fishing uki improves.

  According to the present invention, the fishing rod is attached to the fishing line by fitting the cylindrical fitting shaft through which the fishing line is inserted into the main body, and the cylindrical fitting shaft is pulled out from the main body. Thus, the main body can be removed from the fishing line and replaced with another main body. That is, the fishing hook can be replaced with another type of hook without cutting the fishing line. In addition, since the tubular fitting shaft is securely locked in a state where the tubular fitting shaft is fitted into the main body, the main body does not come off from the fishing line in actual fishing, and the angler fits the annular fixing member into the tubular shape. By removing from the shaft, it is possible to easily release the lock between the cylindrical fitting shaft and the main body. Therefore, the angler can remove the cylindrical fitting shaft from the main body very easily and quickly, and can easily change the fishing base in a short time in actual fishing. In addition, the annular fixing member functions as a weight and stabilizes the fishing ground in water. Therefore, there is no need to attach a weight to the main body, and the structure of the main body can be simplified. As a result, the assembly work of the fishing uki can be facilitated, and the fishing uki can be provided at a low cost.

  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 schematic diagram of a fishing device in which a fishing hook according to the first embodiment of the present invention is used.

  This fishing device 10 is applied to so-called sparkling fishing. The fishing device 10 includes a line 13 supported by a fishing line guide 12 of a fishing rod 11, a fishing vessel 14 attached to the line 13, a Harris 16 connected to the tip of the line 13 via a salcan 15, And a fishhook 17 tied to Harris 16. A suspension member 18 is provided at a predetermined position of the line 13, and a distance from the fishing hook 14 floated on the water surface to the fishhook 17 is set.

  FIG. 2 is a cross-sectional view of the fishing uki 14. FIG. 3 is a front view of the fitting shaft 21 fitted into the fishing lure 14, FIG. 4 is a right side view of the fitting shaft 21, and FIG. 5 is a longitudinal sectional view of the fitting shaft 21. 6 is a sectional view taken along line VI-VI in FIG. 3, and FIG. 7 is a sectional view taken along line VII-VII in FIG.

  As shown in FIG. 2, the fishing ground 14 according to the present embodiment is engaged with the grounding body 20, a fitting shaft 21 (cylindrical fitting shaft) to be inserted into and removed from this, and the fitting shaft 21. And a fixing nut 19 (annular fixing member). As shown in FIG. 1, the fitting shaft 21 is inserted into the main body 20 from above, so that the main body 20 is mounted on the line 13 as shown in FIG. Further, as will be described later, when the fitting shaft 21 is removed from the main body 20, the main body 20 is removed from the line 13.

  As shown in FIG. 2, the fitting shaft 21 is fitted in a through hole 22 provided in the main body 20. The fitting shaft 21 is inserted into and removed from the main body 20 along the direction of the arrow 69, that is, the axial direction of the fitting shaft 21. As shown in FIGS. 3 to 5, the fitting shaft 21 is a cylindrical member. In the present embodiment, the fitting shaft 21 is made of resin (typically acrylonitrile butadiene styrene copolymer (ABS), polypropylene (PP), polyoxymethylene (POM)). However, the material constituting the fitting shaft 21 may be a resin or a metal. The fitting shaft 21 includes a fishing line insertion hole 23. The line 13 (see FIG. 1) is inserted into the fishing line insertion hole 23. The inner diameter dimension of the fishing line insertion hole 23 can be set in the range of 1.0 mm to 3.0 mm. Thereby, lines with various wire diameters can be inserted into the fishing line insertion hole 23. The fishing line insertion hole 23 passes through the center of the fitting shaft 21 and is formed along the axial direction of the fitting shaft 21.

  The fitting shaft 21 includes a main cylindrical portion 24, a flange 25, and a locking rib 26 (engaging portion), which are integrally formed in the present embodiment.

  The main cylindrical portion 24 is set to a predetermined outer diameter dimension d1 (see FIG. 5). This dimension d1 corresponds to the inner diameter dimension d2 of the through-hole 22 provided in the above-mentioned main body 20 (see FIGS. 9 and 10), and a predetermined fitting tolerance is set between them. In the present embodiment, the inner diameter d2 of the through hole 22 is set to 5.0 mm, while the outer diameter d1 of the main cylindrical portion 24 is set to 5.0 mm. That is, the main cylindrical portion 24 is pushed into the through hole 22 of the main body 20 so that a certain frictional force is generated between the main cylindrical portion 24 and the main body 20. Therefore, the fitting shaft 21 is held on the main body 20 with a constant holding force at all times. When the fisherman intentionally inserts or removes the fitting shaft 21 from the main body 20, the fisherman inserts the fitting shaft 21 by operating the fitting shaft 21 with a force exceeding the frictional force. Can be removed. However, the fit tolerance may be a so-called gap tolerance.

  As shown in FIGS. 3 to 5 and 6, a male screw 28 is formed at the lower end portion 27 of the main cylindrical portion 24. A fixing nut 19 which will be described in detail later is screwed into the lower end portion 27. The flange 25 is provided at the upper end of the main cylindrical portion 24. As shown in FIGS. 1 and 2, the flange 25 contacts the upper surface of the main body 20 with the fitting shaft 21 inserted into the main body 20. The flange 25 is formed in a disk shape, and will be described later, but is fitted into a circular recess 42 (see FIGS. 9 and 10) provided on the upper end surface 39 of the main body 20. For this reason, the flange 25 forms the upper surface of the main body 20. Note that the outer shape of the flange 25 is not particularly limited to a disk shape, and may be a shape that allows a fisherman to easily pick with his / her thumb and index finger, for example. In that case, the flange 25 may protrude from the main body 20.

  As shown in FIGS. 3, 4, and 7, the locking rib 26 protrudes from the main cylindrical portion 24. The locking rib 26 is an elongated rod-like member having a rectangular cross-sectional shape. The locking rib 26 is disposed at a boundary portion between the main cylindrical portion 24 and the flange 25, and is provided on the outer peripheral surface of the main cylindrical portion 24. Specifically, the locking rib 26 extends in the axial direction of the main cylindrical portion 24 (downward in FIGS. 3 and 4) and protrudes in the radial direction of the main cylindrical portion 24. The thickness of the locking rib 26 is set to a predetermined thickness dimension t (see FIGS. 4 and 7). In the present embodiment, the thickness dimension t can be set in the range of 1.2 mm to 1.8 mm. Moreover, the height dimension h (refer FIG.3 and FIG.7) of the latching rib 26 is set to 1.2 mm-1.8 mm. The effect of the locking rib 26 will be described later.

  FIG. 8 is a plan view of the main body 20. 9 is a cross-sectional view taken along the line IX-IX in FIG. 8, and FIG. 10 is a cross-sectional view taken along the line XX in FIG.

  As shown in FIGS. 8 to 10, the main body 20 is formed in a substantially spindle shape. However, the lower end of the main body 20 is formed in a plane 38 that is cut by a virtual plane orthogonal to the axial direction. The flat surface 38 constitutes a placement portion 29 on which the fixing nut 19 is placed. As the material constituting the main body 20, resin (typically acrylonitrile butadiene styrene copolymer (ABS), polypropylene (PP), polyoxymethylene (POM)) is adopted in addition to wood.

  The main body 20 includes the through hole 22. This through hole 22 penetrates the center of the main body 20. That is, the through-hole 22 extends in the axial direction of the main body 20 so as to pass from the upper end surface 39 of the main body 20 to the plane 38. Further, the recess 42 is provided in the upper end surface 39. The recess 42 is formed in a circular shape with the through hole 22 as the center, and the flange 25 of the fitting shaft 21 is fitted therein. As described above (see FIG. 2), the flange 25 is accommodated in the recess 42, and the upper surface of the flange 25 constitutes the upper surface of the main body 20; Unstable rocking of the working wall 14 is suppressed.

  The main body 20 includes a slit 32 (see FIGS. 8 and 9). The slit 32 extends in the axial direction (up and down direction in FIG. 9) of the main body 20, and reaches the flat surface 38 from the upper end surface 39 of the main body 20. The slit 32 is cut in the radial direction from the outer peripheral surface 47 of the main body 20 and communicates with the through hole 22. The width d3 (see FIG. 8) of the slit 32 is set in a range of 1.2 mm to 1.8 mm. That is, the width dimension d3 of the slit 32 corresponds to the wall thickness dimension t (see FIGS. 4 and 7) of the locking rib 26 provided on the fitting shaft 21.

  When the main cylindrical portion 24 of the fitting shaft 21 is fitted into the through hole 22, the locking rib 26 is fitted into the slit 32 as shown in FIG. The slit 32 constitutes an engaged portion with which the locking rib 26 is engaged, and the locking rib 26 and the slit 32 function as a key and a key groove. That is, when the fitting shaft 21 is fitted into the main body 20, the locking rib 26 is also fitted with the slit 32, thereby restricting the fitting shaft 21 from rotating in the through hole 22.

  FIG. 11 is a front view of the fixing nut 19. The figure shows a state in which the fixing nut 19 is screwed onto the fitting shaft 21. FIG. 12 is an enlarged plan view of the fixing nut 19. FIG. 13 is a cross-sectional view of the fixing nut 19.

  The fixing nut 19 is made of brass, stainless steel, or other metal having excellent corrosion resistance. The outer shape of the fixing nut 19 is substantially conical. The fixing nut 19 includes a shaft hole 34, and the shaft hole 34 is formed along the axial direction (vertical direction in FIG. 11) so as to penetrate the center of the fixing nut 19. A female screw 35 is formed on the inner peripheral surface of the shaft hole 34 (see FIG. 13). The female screw 35 can be screwed with a male screw 28 formed at the lower end portion 27 of the fitting shaft 21.

  Further, the fixing nut 19 is provided with a slit 36. The slit 36 extends in the axial direction of the fixing nut 19 (the vertical direction in FIG. 11 and the direction perpendicular to the paper surface in FIG. 12), and reaches the lower end surface 49 from the upper end surface 48 of the fixing nut 19. The upper end surface 48 is a flat surface and is formed in a circular shape as shown in FIG. When the fixing nut 19 is screwed into the fitting shaft 21 as described later, the upper end surface 48 comes into contact with the flat surface 38 (see FIG. 9) of the main body 20. As shown in FIG. 12, the slit 36 is cut from the outer surface 37 of the fixing nut 19 along the radial direction and communicates with the shaft hole 34. The slit 36 width dimension d4 is set in the range of 1.2 mm to 1.8 mm, similarly to the width dimension d3 of the slit 32 provided in the above-mentioned main body 20.

  The fishing ground 14 according to the present embodiment is used as follows in actual fishing, and the angler can easily replace the ground body 20.

  The fishing ground 14 is attached to the line 13 in the following manner. First, the fisherman picks up the fitting shaft 21 (see FIG. 3), and inserts the line 13 into the fishing line insertion hole 23 of the fitting shaft 21. Thereby, the fitting shaft 21 is always engaged with the line 13 and can freely slide along the line 13. Next, the angler inserts a portion 40 below the fitting shaft 21 in the line 13 into the main body 20. Specifically, the angler holds the line 13 in his / her hand and inserts the line 13 from the outer peripheral surface 47 of the main body 20 to the through hole 22 through the slit 32 (see FIGS. 8 and 9) of the main body 20. That is, the line 13 is disposed in the through hole 22 through the slit 32.

  The angler inserts the fitting shaft 21 into the through hole 22 from above the ground body 20 (see FIG. 2). That is, the fitting shaft 21 is pushed into the main body 20 from the main cylindrical portion 24. At this time, the locking rib 26 provided in the main cylindrical portion 24 is fitted into the slit 32 and slides along the slit 32. Thereby, the fitting shaft 21 is fitted into the through hole 22, and as a result, the line 13 is disposed in the through hole 22 of the main body 20 while being surrounded by the fitting shaft 21.

  Then, the angler engages the fixing nut 19 with the fitting shaft 21. Specifically, the angler inserts a portion 40 (see FIG. 2) below the fitting shaft 21 of the line 13 from the outer surface 37 of the fixing nut 19 into the slit 36 (see FIG. 12). As shown in FIG. 12, since the slit 36 reaches the shaft hole 34 of the fixing nut 19, the line 13 is disposed in the shaft hole 34 through the slit 36. The angler engages the fixing nut 19 with the lower end portion 27 of the fitting shaft 21 as shown in FIG. That is, the fixing nut 19 is screwed into the lower end portion 27 of the fitting shaft 21.

  When the angler screws in the fixing nut 19, the fixing nut 19 is pressed against the main body 20. That is, the upper end surface 48 of the fixing nut 19 is pressed against and closely contacts the flat surface 38 of the main body 20. As a result, the fitting shaft 21 is fixed in a state of being inserted into the uki body 20 and is prevented from falling off from the uki body 20. That is, the fitting shaft 21 is positioned in the through hole 22 and cannot be detached from the base body 20. Since the line 13 is inserted through the fitting shaft 21 positioned on the main body 20, the main body 20 can be mounted on the line 13 together with the fitting shaft 21 and freely slide along the line 13. it can.

  Since the fixing nut 19 is made of a metal such as brass, it functions as a weight provided on the main body 20. That is, the buoyancy of the main body 20 is set by screwing the fixing nut 19 into the fitting shaft 21. When the weight of the fixing nut 19 is heavy, the residual buoyancy in the water of the main body 20 is small, and when the weight of the fixing nut 19 is light, the residual buoyancy is large. The weight of the fixing nut 19 can be set as appropriate.

  Further, the angler can remove the fixing nut 19 from the fitting shaft 21 and remove the fitting shaft 21 from the main body 20. As a result, the angler can detach the main body 20 from the line 13. That is, the main body 20 is removed from the line 13 without cutting the line 13.

  As described above, according to the fishing uki 14 according to the present embodiment, the fishing shaft 14 is mounted on the line 13 by fitting the fitting shaft 21 into the uki body 20, and the fitting shaft 21 is attached to the ukiuki. By pulling out the main body 20, the main body 20 can be removed from the line 13 and replaced with another main body. That is, the fishing lure 14 can be replaced without cutting the line 13. Moreover, since the fitting shaft 21 is securely coupled to the uki body 20 while being fitted into the uki body 20, the fitting shaft 21 is detached from the uki body 20 and the uki body 20 is detached from the line 13 in actual fishing. There is nothing. However, the angler can easily release the coupling between the fitting shaft 21 and the main body 20 by intentionally removing the fixing nut 19 from the fitting shaft 21. Therefore, the angler can remove the fitting shaft 21 from the main body 20 very easily and quickly in actual fishing, and can perform the exchanging work of the fishing ground in a short time.

  In addition, when the fixed nut 19 is set to a predetermined weight, the fixed nut 19 functions as a weight that adjusts the buoyancy of the fishing lure 14. For this reason, the main body 20 can be easily manufactured as a homogeneous member using resin or the like, and the fixing nut 19 using metal. Then, by attaching the fixing nut 19 to the main body 20, the center of gravity of the fishing base 14 is set. That is, the assembly work and the buoyancy adjustment work of the fishing uki 14 are simple, and as a result, there is an advantage that the fishing uki 14 can be manufactured at low cost.

  Further, in the fishing ground 14 according to the present embodiment, the angler can easily engage the fixing nut 19 with the fitting shaft 21 simply by screwing the fixing nut 19 into the fitting shaft 21. The work of attaching or removing the fixing nut 19 to or from 21 is simple. Therefore, the angler can very easily perform the work of attaching / detaching the fitting shaft 21 to / from the main body 20, and can quickly perform the replacement work of the fishing ground 14 in actual fishing.

  Further, in the present embodiment, as shown in FIG. 2, when the fixing nut 19 is screwed into the fitting shaft 21, the upper end surface 48 of the fixing nut 19 and the plane 38 of the main body 20 come into surface contact, and the fixing nut 19 stably contacts the main body 20. Therefore, the angler can more easily perform the operation of engaging the fixing nut 19 with the fitting shaft 21.

  Further, in this embodiment, when the fitting shaft 21 is inserted into the main body 20, as shown in FIG. 2, the locking rib 26 of the fitting shaft 21 and the slit 32 of the main body 20 are fitted, The fitting shaft 21 is restricted from rotating with respect to the main body 20. That is, the locking ribs 26 and the slits 32 constitute rotation restricting means for the fitting shaft 21 with respect to the main body 20. Therefore, the angler can simply screw the fixing nut 19 into the lower end portion 27 of the fitting shaft 21 by rotating the fixing nut 19 with the fitting shaft 21 inserted into the main body 20.

  By the way, the fishing ground 14 according to the present embodiment includes one fixing nut 19. However, the fishing net 14 may include a plurality of fixing nuts. In that case, the weight of each fixing nut is preferably different from each other. Specifically, for example, a plurality of fixing nuts having different heights b (see FIG. 2) of the fixing nuts are preferably provided.

  By replacing the fixing nut 19 with another fixing nut, the angler can intentionally adjust the remaining buoyancy and the center of gravity of the fishing lure 14. Specifically, for example, when the fisherman wants to zero the residual buoyancy of the fishing lure 14, the fixed nut may be replaced with another heavy nut. If you want to make it larger, replace it with a lighter weight fixing nut.

<Second Embodiment>

  FIG. 14 is a schematic diagram of a fishing device in which a fishing ground according to the second embodiment of the present invention is used.

  This fishing device 100 is applied to so-called sparkling fishing. The fishing device 100 includes a line 113 supported by a fishing line guide 112 of a fishing rod 111, a fishing hook 114 attached to the line 113, and a Harris 116 connected to the tip of the line 113 via a salcan 115, And a fishhook 117 tied to Harris 116. A floating member 118 is provided at a predetermined position of the line 113, and the distance from the fishing hook 114 floated on the water surface to the fishhook 117 is set.

  FIG. 15 is a cross-sectional view of the fishing uki 114. FIG. 16 is a front view of the fitting shaft 121 fitted into the fishing lure 114, FIG. 17 is a right side view of the fitting shaft 121, and FIG. 18 is a longitudinal sectional view of the fitting shaft 121. 19 is a cross-sectional view taken along the line XIX-XIX in FIG. 16, and FIG. 20 is a cross-sectional view taken along the line XX-XX in FIG.

  As shown in FIG. 15, the fishing uki 114 according to the present embodiment is engaged with the uki body 120, a fitting shaft 121 (tubular fitting shaft) that is inserted into and removed from the main body 120, and the fitting shaft 121. And a fixing nut 119 (annular fixing member). As shown in FIG. 14, when the fitting shaft 121 is inserted into the Uki main body 120 from below, the Uki main body 120 is attached to the line 113 as shown in FIG. 14. Further, as will be described later, when the fitting shaft 121 is removed from the main body 120, the main body 120 is removed from the line 113.

  As shown in FIG. 15, the fitting shaft 121 is fitted in a through hole 122 provided in the base body 120. The fitting shaft 121 is inserted into and removed from the main body 120 along the direction of the arrow 69, that is, the axial direction of the fitting shaft 121. As shown in FIGS. 16 to 18, the fitting shaft 121 is a cylindrical member. In this embodiment, the fitting shaft 121 is made of resin (typically acrylonitrile butadiene styrene copolymer (ABS), polypropylene (PP), polyoxymethylene (POM)). However, the material constituting the fitting shaft 121 may be a resin or a metal. The fitting shaft 121 includes a fishing line insertion hole 123. The line 113 (see FIG. 14) is inserted into the fishing line insertion hole 123. The inner diameter dimension of the fishing line insertion hole 123 can be set in the range of 1.0 mm to 3.0 mm. Thereby, lines with various wire diameters can be inserted into the fishing line insertion hole 123. The fishing line insertion hole 123 passes through the center of the fitting shaft 121 and is formed along the axial direction of the fitting shaft 121.

  The fitting shaft 121 includes a main cylindrical portion 124, a flange 125, and a locking rib 126 (engagement portion), which are integrally formed in this embodiment.

  The main cylindrical portion 124 is set to a predetermined outer diameter dimension d1 (see FIG. 18). This dimension d1 corresponds to the inner diameter dimension d2 of the through hole 122 provided in the above-mentioned main body 120 (see FIGS. 22 and 23), and a predetermined fitting tolerance is set between them. In the present embodiment, the inner diameter d2 of the through hole 122 is set to 5.0 mm, while the outer diameter d1 of the main cylindrical portion 124 is set to 5.0 mm. That is, the main cylindrical portion 124 is pushed into the through hole 122 of the main body 120 so that a certain frictional force is generated between the main cylindrical portion 124 and the main body 120. Therefore, the fitting shaft 121 is held on the main body 120 with a constant holding force at all times. When the fisherman intentionally inserts or removes the fitting shaft 121 from the main body 120, the fisherman inserts the fitting shaft 121 by operating the fitting shaft 121 with a force exceeding the frictional force. Can be removed. However, the fit tolerance may be a so-called gap tolerance.

  As shown in FIGS. 16 to 18, a male screw 128 is formed on the upper end portion 127 of the main cylindrical portion 124. A fixing nut 119, which will be described in detail later, is screwed onto the upper end 127. The flange 125 is provided at the lower end of the main cylindrical portion 124. As shown in FIGS. 14 and 15, the flange 125 protrudes from the main body 120 with the fitting shaft 121 inserted into the main body 120. That is, the flange 125 protrudes downward from the lower end surface 139 (see FIG. 15) of the main body 120 in a state where the main cylindrical portion 124 is fitted in the through hole 122. The flange 125 is formed in a disc shape and is in surface contact with the lower end surface 139 of the main body 120. Note that the outer shape of the flange 125 is not particularly limited to a disk shape, and may be a shape that allows a fisherman to easily pick with a thumb and forefinger, for example.

  As shown in FIGS. 16 to 18 and 20, the locking rib 126 protrudes from the main cylindrical portion 124. The locking rib 126 is an elongated rod-like member having a rectangular cross-sectional shape. The locking rib 126 is disposed at a boundary portion between the main cylindrical portion 124 and the flange 125, and is provided on the outer peripheral surface of the main cylindrical portion 124. Specifically, the locking rib 126 extends in the axial direction of the main cylindrical portion 124 (upward in FIGS. 16 and 17) and protrudes in the radial direction of the main cylindrical portion 124. The thickness of the locking rib 126 is set to a predetermined thickness dimension t (see FIGS. 17 and 20). In the present embodiment, the thickness dimension t can be set in the range of 1.2 mm to 1.8 mm. Further, the height dimension h (see FIGS. 16 and 20) of the locking rib 126 is set to 1.2 mm to 1.8 mm. The effect of the locking rib 126 will be described later.

  FIG. 21 is a plan view of the main body 120. 22 is a sectional view taken along line XXII-XXII in FIG. 21, and FIG. 23 is a sectional view taken along line XXII-XXIII in FIG.

  As shown in FIGS. 21 to 23, the main body 120 is formed in a substantially spindle shape. The main body 120 includes an upper part 130 and a lower part 131, and both are joined. The lower part 131 is joined to the upper part 130 by, for example, an adhesive. The material constituting the upper portion 130 is made of wood or resin (typically acrylonitrile butadiene styrene copolymer (ABS), polypropylene (PP), polyoxymethylene (POM)). The lower part 131 is made of a metal such as lead or brass. In other words, the lower portion 131 serves as a weight for keeping the main body 120 in a stable posture in water. Therefore, the center of gravity of the main body 120 is set extremely downward.

  In addition, the lower part 131 may be comprised from the casing which consists of resin, and the weight hold | maintained at this casing. In this case, the casing is fitted with the upper part 130 and fixed to each other. And the said weight is incorporated in a casing. By providing the lower part 131 with such a structure, the weight of the lower part 131 can be set easily and accurately.

  The main body 120 includes the through hole 122. The through hole 122 penetrates the center of the main body 120. That is, the through hole 122 extends in the axial direction of the main body 120 so as to communicate from the upper end 138 of the main body 120 to the lower end surface 139. The upper portion 129 (mounting portion) of the through hole 122 is expanded in diameter. That is, as described above, the inner diameter dimension d2 of the through hole 122 is set to 5 mm (see FIG. 9), and in particular, the inner diameter dimension d4 of the upper portion 129 is set to 8 mm. Therefore, a flat surface 133 (mounting surface) extending in the radial direction of the main body 120 is formed in the upper portion 129 of the through hole 122. However, the inner diameter dimension d4 of the upper portion 129 is not limited to 8 mm, and in short, it may be set larger than the dimension d2 and the plane 133 may be formed in the through hole 122.

  The main body 120 includes a slit 132 (see FIGS. 21 and 22). The slit 132 extends in the axial direction of the main body 120 (vertical direction in FIG. 22) and reaches the lower end surface 139 from the upper end 138 of the main body 120. The slit 132 is cut in the radial direction from the outer peripheral surface 147 of the main body 120 and communicates with the through hole 122. The width d3 of the slit 132 is set in the range of 1.2 mm to 1.8 mm. That is, the width dimension d3 of the slit 132 corresponds to the thickness dimension t (see FIGS. 17 and 20) of the locking rib 126 provided on the fitting shaft 121.

  When the main cylindrical portion 124 of the fitting shaft 121 is fitted into the through hole 122, the locking rib 126 is fitted into the slit 132 as shown in FIG. The slit 132 constitutes an engaged portion with which the locking rib 126 is engaged, and the locking rib 126 and the slit 132 function as a key and a key groove. That is, when the fitting shaft 121 is fitted into the main body 120, the locking rib 126 is also fitted with the slit 132, thereby restricting the fitting shaft 121 from rotating in the through hole 122.

  FIG. 24 is a front view of the fixing nut 119. This figure shows a state in which the fixing nut 119 is screwed to the fitting shaft 121. FIG. 25 is an enlarged plan view of the fixing nut 119.

  The fixing nut 119 is made of brass, stainless steel, or other metal having excellent corrosion resistance. The outer shape of the fixing nut 119 is a hexagon and is formed in an annular shape. The fixing nut 119 includes a shaft hole 134 (see FIG. 25), and the shaft hole 134 is formed along the axial direction (vertical direction in FIG. 24) so as to penetrate the center of the fixing nut 119. An internal thread 135 is formed on the inner peripheral surface of the shaft hole 134. The female screw 135 can be screwed with a male screw 128 formed on the upper end portion 127 of the fitting shaft 121.

  The fixing nut 119 is provided with a slit 136. The slit 136 extends in the axial direction of the fixing nut 119 (a direction perpendicular to the paper surface in FIG. 25), and extends from the upper end surface of the fixing nut 119 to the lower end surface. As shown in FIG. 25, the slit 136 is cut from the outer surface 137 of the fixing nut 119 along the radial direction and communicates with the shaft hole 134. The slit 136 width dimension d5 is set in the range of 1.2 mm to 1.8 mm, similarly to the width dimension d3 of the slit 132 provided in the base body 120 (see FIG. 21). In particular, in the present embodiment, the fixing nut 119 is a so-called hex nut. The slit 136 is configured by cutting the hexagon nut in the radial direction.

  The fishing uki 114 according to the present embodiment is used as follows in actual fishing, and a fisherman can easily exchange the uki body 120.

  The fishing ground 114 is attached to the line 113 in the following manner. First, the angler picks up the fitting shaft 121 and inserts the line 113 into the fishing line insertion hole 123 of the fitting shaft 121 (see FIG. 16). Thereby, the fitting shaft 121 always engages with the line 113 and can freely slide along the line 113. Next, the angler inserts a portion 141 located above the fitting shaft 121 in the line 113 into the main body 120. Specifically, the angler holds the line 113 in his / her hand and inserts the line 113 through the slit 132 (see FIGS. 21 and 22) of the main body 120 from the outer peripheral surface 147 of the main body 120 to the through hole 122. That is, the line 113 is disposed in the through hole 122 through the slit 132.

  The angler inserts the fitting shaft 121 into the through hole 122 from below the main body 120. That is, the fitting shaft 121 is pushed into the main body 120 from the main cylindrical portion 124. At this time, the locking rib 126 provided on the main cylindrical portion 124 fits into the slit 132 and slides along the slit 132. As a result, as shown in FIG. 15, the upper end portion 127 of the fitting shaft 121 enters the upper portion 129 of the through hole 122. That is, the fitting shaft 121 is fitted into the through hole 122, and as a result, the line 113 is disposed in the through hole 122 of the main body 120 while being surrounded by the fitting shaft 121.

  Then, the angler engages the fixing nut 119 with the fitting shaft 121. Specifically, as shown in the figure, the angler inserts the portion 41 of the line 113 above the fitting shaft 121 from the outer surface 137 of the fixing nut 119 into the slit 136 (see FIG. 25). Since the slit 136 reaches the shaft hole 134 of the fixing nut 119, the line 113 is disposed in the shaft hole 134 through the slit 136. As shown in FIG. 15, the angler engages the fixing nut 119 with the upper end portion 127 of the fitting shaft 121. That is, the fixing nut 119 is screwed into the upper end portion 127 of the fitting shaft 121.

  When the angler screws the fixing nut 119, the fixing nut 119 enters the upper portion 129 of the through hole 122 and is pressed against the flat surface 133. Thereby, the fitting shaft 121 is fixed in a state of being inserted into the main body 120, and is prevented from falling off from the main body 120. That is, the fitting shaft 121 is positioned in the through hole 122 and cannot be detached from the main body 120. Since the line 113 is inserted through the fitting shaft 121 positioned in this way, the main body 120 can be mounted on the line 113 together with the fitting shaft 121 and can slide freely along the line 113.

  The angler can also remove the fixing nut 119 from the fitting shaft 121. As a result, the angler can remove the fitting shaft 121 from the main body 120 and disengage the main body 120 from the line 113. That is, the main body 120 is removed from the line 113 without cutting the line 113.

  As described above, according to the fishing lure 114 according to the present embodiment, the fishing shaft 114 is attached to the line 113 by fitting the fitting shaft 121 into the main body 120, and the fitting shaft 121 is mounted on the briquette. By pulling out the main body 120, the main body 120 can be removed from the line 113 and replaced with another main body. In other words, the fishing hook 114 can be replaced without cutting the line 113. Moreover, since the fitting shaft 121 is securely connected to the uki body 120 in a state of being fitted to the uki body 120, the uki body 120 does not come off the line 113 during actual fishing. Further, the fisherman can easily release the connection between the fitting shaft 121 and the main body 120 and remove the main body 120 from the line 113 by removing the fixing nut 119 from the fitting shaft 121. Therefore, the angler can perform the exchanging work for fishing very easily and quickly in actual fishing.

  In the present embodiment, the fixing nut 119 is composed of a hex nut as described above. Therefore, the fixing nut 119 is realized at a low cost. Moreover, the angler can engage the fixing nut 119 with the upper end portion 127 of the fitting shaft 121 very easily, and can easily remove the fixing nut 119 from the engaging shaft 21. That is, the angler can more easily attach and detach the fitting shaft 121 to / from the main body 120, and as a result, replacement work of the main body 120 can be performed more quickly in actual fishing.

  Further, in this embodiment, as shown in FIG. 15, the fixing nut 119 is placed on the flat surface 133, so that the fixing nut 119 is stabilized when being screwed onto the fitting shaft 121 or after being screwed. . Therefore, the angler can more easily perform the operation of engaging the fixing nut 119 with the fitting shaft 121.

  Furthermore, in this embodiment, when the fixing nut 119 is screwed into the fitting shaft 121, the fixing nut 10 is accommodated in the upper portion 129 of the through hole 122. That is, since the fixing nut 119 is disposed inside the main body 120, in the actual fishing, it is suppressed that the fishing base 114 swings unstable due to the wind of the fixing nut 119. But the said through-hole 122 may be comprised as a hole with a constant internal diameter, without expanding the diameter in the middle. That is, the plane 133 may be configured by the upper surface of the main body 120, and in that case, the fixing nut 119 is placed on the upper surface of the main body 120.

  In addition, in this embodiment, when the fitting shaft 121 is inserted into the main body 120, as shown in FIG. 15, the locking rib 126 of the main shaft 121 and the slit 132 of the main body 120 are engaged. The rotation of the fitting shaft 121 relative to the main body 120 is restricted. That is, the locking rib 126 and the slit 132 constitute a rotation restricting unit for the fitting shaft 121 with respect to the main body 120. Therefore, the angler can simply screw the fixing nut 119 into the upper end portion 127 of the fitting shaft 121 simply by rotating the fixing nut 119 with the fitting shaft 121 inserted into the main body 120.

  The locking rib 126 may be omitted. In that case, the inner peripheral surface shape of the upper portion 129 of the through hole 122 may be formed in a hexagonal shape corresponding to the outer shape of the fixing nut 119 instead of the circular shape. In this configuration, since the rotation of the fixing nut 119 is restricted in a state where the fixing nut 119 is placed on the flat surface 133, the angler can simply fit the fixing nut 119 by rotating the fitting shaft 121. The mating shaft 121 can be engaged. However, the shape of the inner wall surface of the upper portion 129 of the through hole 122 may be another shape that can regulate the rotation of the fixing nut 119 in the upper portion 129 instead of the hexagon.

  Next, a modification of this embodiment will be described.

  The fishing lure 114 according to this embodiment includes one fixing nut 119. However, the fishing float 114 may include a plurality of fixing nuts. In that case, the weight of each fixing nut is preferably different from each other. Specifically, it is preferable that a plurality of fixing nuts having different height dimensions b (see FIG. 24) are provided (first modification).

  As described above, since the lower part 131 of the above-mentioned main body 120 serves as a weight provided on the main body 120, the center of gravity of the fishing base 114 is set at the extreme lower part. In fishing, the fishing uki 114 maintains a stable posture in water. However, when the weight of the lower portion 131 is adjusted, the residual buoyancy of the fishing uki 114 may become almost zero. At this time, the fishing uki 114 floats below the surface of the water in actual fishing. In such a case, the fishing uki 114 may maintain a stable posture in water when the center of gravity is set at a position closer to the center than when it has an extremely low center of gravity.

  In the first modification, the angler can easily replace one fixing nut with another fixing nut. Thereby, the angler can intentionally adjust the residual buoyancy and the center of gravity of the fishing lure 114. Specifically, for example, when the fisherman wants to zero the residual buoyancy of the fishing lure 114, the fixed nut is replaced with another fixed nut having a heavy weight. Accordingly, the buoyancy of the fishing uki 114 is suppressed and the center of gravity of the fishing uki 114 moves to the center side, so that the fishing uki 114 maintains a stable posture in water.

  FIG. 26 is a front view of a fitting shaft according to a second modification of the present embodiment, and FIG. 27 is a side view.

  In the above embodiment, the flange 125 is provided at the lower end of the fitting shaft 121, but in this modification, a knob 143 is provided on the flange 125. The knob 143 is flat and includes flat portions 144 and 145. The fishing line insertion hole 123 also penetrates the knob 143. The angler can easily grasp the knob 143 with a finger. Therefore, the angler can more easily perform the insertion / removal operation of the fitting shaft 121.

<Third Embodiment>

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

  In the second embodiment, the main body 120 has an upper part 130 and a lower part 131 (see FIG. 15), and the main part 120 is assembled by joining them together. However, when the main body 120 is made of resin, the main body 120 may have a structure as shown in FIG.

  28 is a plan view of the main body 160 according to the third embodiment of the present invention, and FIGS. 29 and 30 are a XXIX-XXIX sectional view and a XXX-XXX sectional view in FIG. 28, respectively.

  This uki body 160 has the same external shape as the uki body 120 according to the second embodiment, and includes a through hole 122 and a slit 132. In addition, the uki body 160 includes an upper body 161 and a lower body 162 like the uki body 120, and the uki body 160 is assembled by fitting them together.

  The difference between the uki body 160 and the uki body 120 is that the uki body 120 has an upper portion 130 and a lower portion 131 made of solid material (see FIG. 15), whereas the uki body 160 according to the present embodiment. The upper main body 161 and the lower main body 162 constituting the above are formed in a hollow container shape. Thus, since the upper main body 161 and the lower main body 162 have a hollow structure, the upper main body 161 and the lower main body 162 can be easily configured by injection molding with resin. As a result, there is an advantage that mass production of the main body 160 is possible and the fishing ground 114 is provided at a low cost.

  Specifically, the upper main body 161 includes an outer shell portion 163 and an inner shaft portion 164 formed in a substantially hemispherical shell shape. These are integrally formed. The thickness dimension of the upper main body 161 varies depending on the strength of the resin constituting the upper main body 161, but can be set to about 1 mm to 3 mm. The inner shaft portion 164 is formed in a cylindrical shape, and as shown in FIG. 30, is provided at the center inside the outer shell portion 163 and protrudes downward (to the lower main body 162 side). The inner wall surface of the inner shaft portion 164 constitutes the upper portion 171 of the through hole 122. The upper portion 129 of the through hole 122 is enlarged in the same manner as in the second embodiment, and a flat surface 133 is formed. Further, the upper main body 161 has a groove 165 cut in the radial direction from the outer peripheral surface 147, and the groove 165 constitutes a part of the slit 132.

  The lower main body 162 includes an outer shell portion 166 and an inner shaft portion 167 formed in a substantially funnel shape. These are integrally formed like the upper main body 161. The wall thickness dimension of the lower main body 162 can be set to about 1 mm to 3 mm similarly to the upper main body 161. The inner shaft portion 167 is formed in a cylindrical shape, and as shown in FIG. 30, is provided at the center inside the outer shell portion 166 and protrudes upward (to the upper main body 161 side). A lower portion 172 of the through hole 122 is constituted by the inner wall surface of the inner shaft portion 167. The lower main body 162 has a groove 168 cut in the radial direction from the outer peripheral surface 147, and the groove 168 constitutes a part of the slit 132.

  As shown in FIGS. 29 and 30, the upper body 161 is fitted to the lower body 162 in the vertical direction (in the axial direction). As a result, the outer peripheral surface 147 of the upper main body 161 and the outer peripheral surface 147 of the lower main body 162 are smoothly continuous, and a substantially spindle-shaped Uki main body 160 is formed. In the present embodiment, a so-called agitation structure is formed on the opposing surfaces of the outer shell portion 163 and the outer shell portion 166. Thereby, when the upper main body 161 and the lower main body 162 are fitted together, both are positioned. Further, the inner shaft portion 164 and the inner shaft portion 167 are fitted together in a state where the outer shell portion 163 and the outer shell portion 166 are fitted. The inner shaft portion 164 and the inner shaft portion 167 are also formed with a facing structure so that the inner shaft portion 164 and the inner shaft portion 167 are reliably joined in a positioned state.

  As described above, the upper body 161 and the lower body 162 are fitted together, whereby the groove 165 and the groove 168 are continuous in the axial direction to form the slit 132, and the inner shaft portion 164 and the inner shaft portion 167 are also formed.

  Next, a modification of the third embodiment will be described.

  31 is a plan view of the main body 180 according to a modification of the present embodiment, and FIGS. 32 and 33 are a XXXII-XXXII sectional view and a XXXIII-XXXIII sectional view in FIG. 31, respectively.

  The difference between the uki body 180 according to this modification and the uki body 160 according to the third embodiment is that the uki body 160 is directly fitted with the upper body 161 and the lower body 162 ( 29 and FIG. 30), in the Uki main body 180 according to this modification, a joining plate 183 is disposed between the upper main body 181 and the lower main body 182, and both of them are securely connected via this joining plate 183. The fixed point and the depth dimension c2 (see FIG. 32) of the upper part 189 of the through hole 122 are set larger than the depth dimension c1 (see FIG. 29) of the upper part 129 of the through hole 122 of the above-mentioned main body 160. It is a point. Other configurations are the same as those of the main body 160.

  The upper body 181 includes a substantially hemispherical outer shell 163 and a cylindrical inner shaft 164 as in the third embodiment. These are integrally formed. The lower end surface 84 of the outer shell portion 163 has a shape that is uneven in the vertical direction. This concavo-convex shape matches the concavo-convex shape of the outer peripheral edge of the joining plate 183 described in detail later. As shown in FIG. 33, the inner shaft portion 164 is provided at the center inside the outer shell portion 163 and protrudes downward (to the lower main body 182 side). The inner wall surface of the inner shaft portion 164 constitutes the upper portion 171 of the through hole 122. The upper portion 171 of the through hole 122 is enlarged in diameter, and the upper portion 171 constitutes the upper portion 189 of the through hole 122 and the plane 133 is formed. Further, the upper body 181 has a groove 165 cut in the radial direction from the outer peripheral surface 147, and this groove 165 constitutes a part of the slit 132.

  Similarly to the third embodiment, the lower main body 182 includes a substantially funnel-shaped outer shell portion 166 and a cylindrical inner shaft portion 167, which are integrally formed. The upper end surface 185 of the outer shell portion 166 has a shape that is uneven in the vertical direction. This concavo-convex shape matches the concavo-convex shape of the outer peripheral edge of the joining plate 183 described in detail later. As shown in FIG. 33, the inner shaft portion 167 is provided at the center inside the outer shell portion 166, and protrudes upward (to the upper main body 181 side). A lower portion 172 of the through hole 122 is constituted by the inner wall surface of the inner shaft portion 167. The lower main body 162 has a groove 168 cut in the radial direction from the outer peripheral surface 147, and the groove 168 constitutes a part of the slit 132.

  FIG. 34 is a plan view of the joining plate 183.

  As shown in FIGS. 33 and 34, the joining plate 183 is formed in a disc shape. The joining plate 183 is made of a resin (typically acrylonitrile butadiene styrene copolymer (ABS), polypropylene (PP), polyoxymethylene (POM)) in the same manner as the upper main body 181 and the lower main body 182. The outer diameter of the joining plate 183 matches the outer diameter of the lower end surface 184 of the upper main body 181 and the outer diameter of the upper end surface 185 of the lower main body 182. The joining plate 183 includes ribs 191 and 192. The rib 191 is formed in a ring shape, and is erected on the peripheral edge of the upper surface of the bonding plate 183. The ribs 192 are also formed in a ring shape, and are erected on the periphery of the lower surface of the bonding plate 183. The rib 191 and the rib 192 are arranged symmetrically in the vertical direction. Thereby, the outer periphery of the joining board 183 becomes a shape uneven | corrugated to an up-down direction.

  A boss 193 is provided at the center of the bonding plate 183. Seats 194 and 195 are formed on the upper and lower surfaces of the boss 193, respectively. Each seat 194, 195 is formed of a circular recess, the inner diameter of the seat 194 corresponds to the outer diameter of the inner shaft 164 of the upper body 181, and the inner diameter of the seat 195 is the inner shaft of the lower body 182. This corresponds to an outer diameter of 167. For this reason, as shown in FIG. 33, the inner shaft portion 164 and the inner shaft portion 167 are surely fitted to the boss 193 without causing rattling. Further, a hole 196 that penetrates the center of the boss 193 is provided. The hole 196 constitutes a part of the through hole 122. Therefore, in a state where the inner shaft portion 164 and the inner shaft portion 167 are fitted to the boss 193, the upper portion 171, the lower portion 172, and the hole 196 of the through hole 122 communicate with each other to form the through hole 122. It is like that.

  Further, as shown in FIG. 34, a groove 197 is provided in the joining plate 183. The groove 197 is cut in the radial direction from the outer peripheral surface 198 of the bonding plate 183 and reaches the hole 196 provided in the boss 193. The width dimension d6 of the groove 197 coincides with the width dimension of the groove 165 provided in the upper body 181 and the width dimension of the groove 168 provided in the lower body 182. Therefore, the groove 197 provided in the joining plate 183 constitutes a part of the slit 132.

  As shown in FIGS. 32 and 33, the upper main body 181 is fitted to the lower main body 182 in the vertical direction (in the axial direction) with the joining plate 183 interposed therebetween. As a result, the outer peripheral surface 147 of the upper main body 181 and the outer peripheral surface 147 of the lower main body 182 are smoothly continuous, and a substantially spindle-shaped Uki main body 180 is formed.

  Specifically, the joining plate 183 is placed on the upper end surface 185 of the lower main body 182. At this time, the joining plate 183 is disposed so that the position of the groove 168 of the lower main body 182 and the position of the groove 197 of the joining plate 183 coincide with each other. As described above, since the concavo-convex shape formed on the upper end surface 85 of the lower main body 182 and the concavo-convex shape formed on the outer peripheral edge of the lower surface of the bonding plate 183 correspond to each other, the bonding plate 183 has an abrupt structure And is joined to the lower main body 182 in a positioned state.

  Further, the upper body 181 is placed on the joining plate 183. At this time, the upper body 181 is arranged so that the position of the groove 165 of the upper body 181 and the position of the groove 197 of the bonding plate 183 coincide. As described above, since the concavo-convex shape formed on the lower end surface 184 of the upper body 181 and the concavo-convex shape formed on the outer peripheral edge of the upper surface of the bonding plate 183 correspond, It is joined to the joining plate 183 through the positioning in a positioned state.

  When the upper body 181 and the lower body 182 are joined to the joining plate 183, the inner shaft portion 164 of the upper body 181 is fitted into the seat portion 194 of the boss 193 of the joining plate 183, and the inner shaft portion 167 of the lower body 182 is fitted to the boss. The seat 195 is fitted into the seat 195. That is, in the uki body 180 as a structure, the joining plate 183 functions as a beam, and thus the rigidity of the uki body 180 is dramatically improved.

  As described above, the upper body 181, the joining plate 183, and the lower body 182 are fitted together, whereby the groove 165, the groove 168, and the groove 197 are continuous in the axial direction to form the slit 132 and the inner shaft. The through-hole 122 is configured by the portion 164, the boss 193, and the inner shaft portion 167 being continuous in the axial direction. Then, when the fitting shaft 121 is inserted into and removed from the uki body 180, the angler can easily attach and detach the uki body 180 to the line 113.

  The Uki main body 180 according to this modification has extremely high rigidity because the bonding plate 183 is provided. Therefore, even if the fishing uki 114 collides with a rod or the like during actual fishing, the uki main body 180 is not easily damaged. In addition, since the upper part 189 of the through hole 122 is formed very deep as shown in FIG. 33, the fixing nut 119 is surely fitted in the main body 180 even if the height dimension b of the fixing nut 119 increases. Is housed in. Moreover, since the fixing nut 119 set to various height dimensions b can be attached to the main body 180, there is also an advantage that the remaining buoyancy of the fishing base 114 can be widely adjusted.

  The present invention can be applied to a ground used for ground fishing.
