Description

The present invention relates to a fishing line fastener and a fishing line fastener set.

Fishing line holders that secure fishing lines to fishing rods have been known for some time. For example, Patent Document 1 proposes a line holder that is shaped like a clothespin. In this line holder, an elastic member is provided on the inner surface of the clamping part that clamps the object. The fishing line is then attached to the fishing rod by aligning it along the length of the rod and clamping both the rod and the fishing line together in this state with the clamping part of the line holder. This makes it possible to prevent the fishing line from coming off the rod when you are taking a break from fishing.

In addition, when fishing with a reel, a line stopper is used. A line stopper is a tool that prevents the line (fishing line) wound on the reel from becoming loose. There are two types of line stoppers: one that is attached to the reel and one that is used separately from the reel. The type of line stopper that is used separately from the reel has a main body and a line stopper. In one example of such a line stopper, the line stopper is made of a wire that is bent into a U-shape so as to be folded, and when the line is passed through the U-shaped part of the wire, the line is clamped by the U-shaped part. In another example of the line stopper, a slit that constitutes the line stopper is formed from one side of the elastic plate-like body that constitutes the main body toward the inside, and when the line is passed through this slit, the line is clamped by the slit.

JP-A-08-051899 (see FIG. 5 in particular)

However, with the line stopper of Patent Document 1, the only part where the full pressure from the line stopper acts is the linear part where the normal to the circumferential surface of the fishing rod coincides with the normal to the inner surface of the clamping part of the line stopper (see Figure 5 of Patent Document 1), and one of the surfaces that clamps the fishing line is the circumferential surface of the fishing rod and does not actually elastically deform in the normal direction. For example, if the fishing line is thin, the clamping force acting on the fishing line may be insufficient.

In addition, in the above-mentioned conventional line stoppers used alone, no pressure is applied to the line stopper when the line is not passing through, so for example, if the fishing line is thin, the stopping force acting on the line may not be sufficient.

The present invention was made to solve the above problems, and aims to provide a fishing line fastener and fishing line fastener set that exerts a sufficient fastening force on the fishing line even when the fishing line is thin.

In order to achieve the above object, a fishing line clip according to one aspect of the present invention comprises a first clamping member having a convex first end portion including a first end face, the first clamping surface being elastically deformable in a normal direction constituting a surface of the first end portion , a second clamping member having a convex second end portion including a second end face, the second clamping surface being elastically deformable in a normal direction constituting a surface of the second end portion, and a pressure coupling structure having a coupling axis, the first clamping surface being elastically deformable in a normal direction constituting a surface of the second end portion. The second clamping surface includes a first annular inner circumference having a central axis, a first annular contact surface that extends between the first outer circumference and the first inner circumference and is a tip surface included in the first end surface and is substantially perpendicular to the coupling axis, and a first inclined surface that rises inwardly and obliquely from the first outer circumference to reach the first contact surface, and the second clamping surface includes a second outer circumference located on the base end side of the second end , a second annular inner circumference having a central axis along the coupling axis, and a tip surface that extends between the second outer circumference and the second inner circumference and is included in the second end surface. and a second inclined surface extending inwardly and obliquely from the second outer periphery to the second contact surface, the first clamping member and the second clamping member are arranged such that the first inner periphery and the second inner periphery are coaxial with each other and the first contact surface and the second contact surface are in contact with each other, and the pressurized joining structure includes a cylindrical hole portion having a central axis equal to the joining axis, and a cylindrical shaft portion having a central axis equal to the joining axis and fitted into the hole portion. The hole portion is provided in the second clamping member so as to open into the opening surface of the second inner circumference, and the shaft portion is provided in the first clamping member so as to protrude from the opening surface of the first inner circumference , and the shaft portion is screwed into the hole portion or press-fitted into the hole portion, so that the first clamping member and the second clamping member are joined to each other via the shaft portion fitted into the hole portion in a state in which they are pressurized against each other in a direction along the joining axis by the pressurized joining structure.

According to this configuration, when the fishing line is moved along the first clamping surface of the first clamping member or the second clamping surface of the second clamping member toward the shaft of the pressure connection structure with the fishing line taut, the fishing line is first guided to the first clamping surface of the first clamping member or the second clamping surface of the second clamping member, and then the fishing line is clamped by the first contact surface of the first clamping member and the second contact surface of the second clamping member. In this case, the first contact surface of the first clamping member and the second contact surface of the second clamping member are in surface contact with each other and pressurized, and both the first contact surface and the second contact surface are elastically deformed in their normal directions, so that even if the fishing line is thin, the fishing line can be fastened to the fishing line fastener with a sufficient fastening force acting on the fishing line. Furthermore, according to this configuration, a separate member for pressure-connecting the first clamping member and the second clamping member is not required, and the pressure connection structure is simplified.

The first clamping member and the second clamping member may be made of an elastic material.

This simple configuration allows the first clamping surface of the first clamping member and the second clamping surface of the second clamping member to be elastically deformed in the normal direction.

The first clamping member or the second clamping member may be provided with an attachment portion for attaching the first clamping member or the second clamping member to a fishing rod.

With this configuration, the fishing line holder can be attached to the fishing rod using the attachment part, and as a result, the fishing line can be prevented from coming off the fishing rod when you are taking a break from fishing.

According to another aspect of the present invention, a fishing line holder set includes a first clamping member having a convex first end portion including a first end face, the first clamping surface being elastically deformable in a normal direction constituting a surface of the first end portion , and a second clamping member having a convex second end portion including a second end face, the second clamping surface being elastically deformable in a normal direction constituting a surface of the second end portion, the first clamping member and the second clamping member each including a pressure joint structure having a first central axis and a second central axis, the first clamping surface being elastically deformable in a normal direction constituting a surface of the first end portion. the first contact surface includes a first outer periphery located on the base end side of the second end portion , a first annular inner periphery having the first central axis as a central axis, a first annular contact surface extending between the first outer periphery and the first inner periphery and being a tip surface included in the first end face and being substantially perpendicular to the first central axis, and a first inclined surface rising inwardly and obliquely from the first outer periphery to reach the first contact surface, and the second clamping surface includes a second outer periphery located on the base end side of the second end portion , a second annular inner periphery having the second central axis as a central axis, and a first inclined surface extending between the second outer periphery and the second inner periphery and the second end surface includes a second annular contact surface that is a tip surface included in the second end surface and is substantially perpendicular to the second central axis, and a second inclined surface that rises inwardly and obliquely from the second outer periphery to reach the second contact surface, the pressurized coupling structure includes a cylindrical hole portion whose central axis is the second central axis, and a cylindrical shaft portion whose central axis is the first central axis and that fits into the hole portion, the hole portion being provided in the second clamping member so as to open into an opening surface of the second inner periphery, and the shaft portion being provided in the first clamping member so as to open into an opening surface of the first inner periphery In a state in which the first clamping member and the second clamping member are arranged so that the first central axis and the second central axis substantially coincide to form a joining axis, the first inner circumference and the second inner circumference are coaxial, and the first contact surface and the second contact surface are in contact with each other, the shaft portion can be screwed or pressed into the hole portion to join the first clamping member and the second clamping member to each other via the shaft portion in a state in which the first clamping member and the second clamping member are pressed against each other in a direction along the joining axis.

According to this configuration, the first clamping member and the second clamping member are arranged so that the first inner circumference and the second inner circumference are coaxial and the first contact surface and the second contact surface are in contact with each other. Then, by screwing or pressing the shaft into the hole, the first clamping member and the second clamping member are joined to each other via the shaft while being pressed against each other in a direction along the joining axis, a fishing line fastener can be obtained that exerts a sufficient fastening force on the fishing line even when the fishing line is thin.

The present invention has the effect of providing a fishing line fastener and fishing line fastener set that exerts a sufficient fastening force on the fishing line even when the fishing line is thin.

(Embodiment 1)

[composition]
Fig. 1 is an external view showing an example of the configuration of a fishing line holder 100 according to a first embodiment of the present invention. Fig. 2 is an external view showing an example of the configuration of a first clamping member 1 of Fig. 1. Fig. 3 is an external view showing an example of the configuration of a second clamping member 2 of Fig. 1. Fig. 4 is a cross-sectional view showing a vertical section of the fishing line holder 100 of Fig. 1. Fig. 4 shows a longitudinal section of the fishing line holder 100 including the coupling axis A0 in Fig. 1. Figs. 1 to 3 are drawings created by sketching the objects shown in the drawings.

Referring to FIG. 1, the fishing line holder 100 includes a first clamping member 1 and a second clamping member 2. Referring to FIG. 4, the fishing line holder 100 further includes a pressure coupling structure 10 having a coupling axis A0.

{First clamping member 1}
Structure
Referring to FIG. 2, the first clamping member 1 includes a main body 11 and a shaft portion 12. The overall shape of the main body 11 is not particularly limited as long as it has a first clamping surface Fp1 described below. The main body 11 has, for example, a hemispherical shape. In the main body 11, the base end surface of this hemispherical shape constitutes the first clamping surface Fp1. The first clamping surface Fp1 includes a first outer periphery Co1 which is the base end, a first inner periphery Ci1 which is an annular shape with a first central axis A1 as the central axis, a first contact surface Fc1 which is an annular tip surface extending between the first outer periphery Co1 and the first inner periphery Ci1 and perpendicular to the first central axis A1, and a first inclined surface Fs1 which rises inwardly and obliquely from the first outer periphery Co1 to reach the first contact surface Fc1. The first inclined surface Fs1 plays a role of guiding the fishing line 5 as described later (see FIG. 5 and FIG. 8), so it is necessary that it is smooth, but other than that, it is not particularly limited. Here, the first inclined surface Fs1 is an inclined surface having a constant inclination (see FIG. 4), but may be an inclined surface whose inclination becomes gentler from the base end to the tip end. The first clamping surface Fp1 can be elastically deformed in the normal direction. A part (not shown) that serves as a clue when screwing the first clamping member 1 to the second clamping member 2 may be formed on the hemispherical tip end surface of the main body 11. Examples of such a clue include a rib of an appropriate shape (for example, a cross shape), a matte finish, etc. Also, the main body 11 may be formed in a polygonal pyramid shape, and the first clamping surface Fp1 may be formed on the base end surface. In this case, the ridge of the polygonal pyramid on the tip end surface serves as the clue.

The main body 11 is provided with a shaft portion 12 that protrudes from the opening surface of the first inner circumference Ci1 of the first contact surface Fc1. The shaft portion 12 has a first central axis A1 as its central axis. A male thread is formed on the outer peripheral surface of the shaft portion 12. Here, the outer periphery of the shaft portion 12 coincides with the first inner circumference Ci1 of the first contact surface Fc1. The base of the shaft portion 12 may be formed in a short cylindrical shape without a male thread (see embodiment 3 and FIG. 9). The effect of this will be described later.

<Material>
At least the outer portion of the first clamping member 1 is made of an elastic material, so that the first clamping surface Fp1 is elastically deformable in the normal direction.

Examples of materials for this elastic body include rubbers such as synthetic rubber and natural rubber. Examples of synthetic rubber include silicone rubber, butadiene rubber, isoprene rubber, styrene-butadiene rubber, ethylene-propylene rubber, butyl rubber, chloroprene rubber, acrylonitrile-butadiene rubber, acrylic rubber, urethane rubber, and fluororubber. Of these, silicone rubber is particularly preferred as a material for the elastic body. This is because silicone rubber has a high frictional force.

The elasticity of the elastic body may be at a general level. In the case of rubbers, the "general level" of elasticity means the elasticity level of rubber products that are generally traded. The elasticity of rubbers can be conveniently substituted by tensile strength. For silicone rubber, the preferred tensile strength (test method: JIS K6301) range is 40 to 100 kgf/cm2. For natural rubber, the preferred tensile strength range is 30 to 300 kgf/cm2. For rubbers in general, the preferred tensile strength range is 20 to 300 kgf/cm2. For rubbers in general, the preferred JIS hardness range can be conveniently substituted by JIS hardness. For silicone rubber, the preferred JIS hardness (test method: JIS K6301) range is 30 to 90. For natural rubber, the preferred JIS hardness range is 10 to 100. For rubbers in general, the preferred JIS hardness range is 10 to 100. For more information on the rubber properties listed above, please refer to the document at the following URL: <https://kayo-corp.co.jp/common/pdf/rub_propertylist.pdf>.

In one example created according to this embodiment, the elastic body was made of silicone rubber and had a tensile strength of 96 kgf/cm2. Note that the above elasticity range is an example, and the elasticity may be outside this range.

The first clamping member 1 may be entirely made of an elastic material, or the outer portion may be made of an elastic material and the inner portion may be made of a rigid material. Here, the first clamping member 1 is entirely made of an elastic material.

{Second clamping member 2}
Structure
3, the second clamping member 2 includes a main body 21, a hole 22, and an attachment portion 23. The overall shape of the main body 21 is not particularly limited as long as it has a second clamping surface Fp2 described below. The main body 21 has, for example, a short cylindrical shape. In the main body 21, one end face of the short cylindrical shape constitutes the second clamping surface Fp2. The second clamping surface Fp2 includes a second outer periphery Co2 which is a base end, a second inner periphery Ci2 which is an annular shape having a second central axis A2 as a central axis, a second contact surface Fc2 which is an annular tip surface extending between the second outer periphery Co2 and the second inner periphery Ci2 and is perpendicular to the second central axis A2, and a second inclined surface Fs2 which rises inwardly and obliquely from the second outer periphery Co2 to reach the second contact surface Fc2. The second slope Fs2, as described below, serves to guide the fishing line 5 (see Figs. 5 and 8), and therefore needs to be smooth, but is not otherwise limited. Here, the second slope Fs2 is a slope that becomes gentler from the base end to the tip end (see Fig. 4), but may be a slope with a constant slope. In addition, the second clamping surface Fp2 is elastically deformable in the normal direction.

The body 21 is provided with a hole 22 that opens into the opening surface of the second inner circumference Ci2 of the second contact surface Fc2. The hole 22 is formed in a cylindrical shape with the second central axis A2 as the central axis. A female thread that screws into the male thread of the shaft portion 12 of the first clamping member 1 is formed on the inner peripheral surface of the hole 22. The hole 22 is formed to a depth equal to or greater than the depth corresponding to the length of the shaft portion 12 of the first clamping member 1. In addition, when the hole 22 is formed to a depth equal to or greater than the depth corresponding to the length of the shaft portion 12 of the first clamping member 1, the tip portion (rear portion) of the hole 22 may be formed into a short cylindrical space 22a in which no female thread is formed. The diameter of this space 22a is formed to be larger than the diameter of the valley (groove) of the female thread. The effects of these will be described later.

Note that, as shown in FIG. 4, the other end surface of the main body 21 is formed with a shallow recess, but this recess may be omitted.

A pair of mounting parts 23, 23 are provided on the lower part of the opposite side surfaces of the main body 21 so as to protrude radially outward from the lower part of the opposite side surfaces of the main body 21. The shape of the pair of mounting parts 23, 23 is not particularly limited as long as it allows the main body 21 to be attached to the fishing rod 4. Here, the pair of mounting parts 23, 23 are each formed to have an L-shaped vertical cross section. The rising parts 23a of the pair of mounting parts 23, 23 are the parts to which an O-ring serving as an auxiliary device is engaged when attaching the fishing line holder 100 to the fishing rod 4, as described below (see FIG. 7).

<Material>
The material of the second clamping member 2 is the same as the material of the first clamping member 1 .

{Pressure bonding structure 10}
4, the pressurized joint structure 10 includes a shaft portion 12 of the first clamping member 1 and a hole portion 22 of the second clamping member 2. The shaft portion 12 is provided so as to protrude from the opening surface of the first inner circumference Ci1 of the first clamping member 1, and the hole portion 22 is provided so as to open into the opening surface of the second inner circumference Ci2 of the second clamping member 2. Therefore, there may be a gap between the shaft portion 12 and the first inner circumference Ci1. For example, a ring-shaped recess may be formed between the first inner circumference Ci1 and the shaft portion 12. There may also be a gap between the hole portion 22 and the second inner circumference Ci2. For example, the inside of the second inner circumference Ci2 may be formed into a recess, and the hole portion 22 may open into the recess.

In the fishing line fastener 100, for example, when a worker or user of the manufacturing company screws the shaft 12 of the first clamping member 1 to the base end into the hole 22 of the second clamping member 2 with normal force, the first clamping member 1 is fastened to the second clamping member 2 with a pressure force corresponding to the elastic deformation due to the elastic deformation of the first clamping member 1 and the second clamping member 2. In this case, the first clamping member 1 and the second clamping member 2 are connected to each other via the shaft 12 and the hole 22 in a state where they are pressurized in a direction along the coupling axis A0, with the first inner circumference Ci1 and the second inner circumference Ci2 being coaxial and the first contact surface Fc1 and the second contact surface Fc2 being arranged so as to be in contact with each other. In this state, the first central axis A1 of the first clamping member 1 and the second central axis A2 of the second clamping member 2 substantially coincide with the coupling axis A0. Therefore, in this pressure-bonded structure, the central axis of the shaft portion 12 and the hole portion 22 is substantially the bond axis A0, the first contact surface Fc1 and the second contact surface Fc2 are substantially perpendicular to the bond axis A0, and the first inner circumference Ci1 and the second inner circumference Ci2 are substantially perpendicular to the bond axis A0.

Here, if the depth of the hole 22 of the second clamping portion is formed deeper than the depth corresponding to the length of the shaft portion 12 of the first clamping member 1, and further, if the tip (rear portion) of the hole 22 is formed as a short cylindrical space 22a with a diameter larger than the diameter of the valley of the female thread, it is possible to apply more force to rotate the first clamping member 1 and tighten the first clamping member 1 to the second clamping member 2 from the state in which the first clamping member 1 is fastened to the second clamping member 2 with normal force as described above (hereinafter referred to as "re-tightening").

[Action and Effect]
Fig. 5 is a cross-sectional view showing the effect of the fishing line holder 100 of Fig. 1. Referring to Fig. 5, according to the fishing line holder 100 configured as described above, when the fishing line 5 is moved along the first clamping surface Fp1 of the first clamping member 1 or the second clamping surface Fp2 of the second clamping member 2 toward the shaft portion 12 of the pressure coupling structure 10 with the fishing line 5 in a taut state, the fishing line 5 is first guided to the first clamping surface Fp1 of the first clamping member 1 or the second clamping surface Fp2 of the second clamping member 2, and then the fishing line 5 is clamped between the first contact surface Fc1 of the first clamping member 1 and the second contact surface Fc2 of the second clamping member 2. In this case, the first contact surface Fc1 of the first clamping member 1 and the second contact surface Fc2 of the second clamping member 2 are in surface contact with each other and pressurized, and both the first contact surface Fc1 and the second contact surface Fc2 elastically deform in their respective normal directions, so that a sufficient stopping force acts on the fishing line 5 even if the fishing line 5 is thin.

[how to use]
As mentioned above, the force can be increased by tightening the fastener 12. If the fishing line 5 is particularly thin, it may be desirable to wind the fishing line 5 around the shaft 12. This can increase the force exerted on the fishing line 5.

Figure 6 is an external view showing the configuration of the O-ring 3 for attaching the fishing line holder 100 of Figure 1 to the fishing rod 4. Figure 7 is an external view showing the fishing line holder 100 of Figure 1 attached to the fishing rod 4. Figure 8 is an external view showing the fishing line 5 fastened to the fishing line holder 100 attached to the fishing rod 4.

Referring to FIG. 6, an O-ring 3, for example, is prepared as an auxiliary tool for attaching the fishing line holder 100 to the fishing rod 4. There are no particular limitations on the auxiliary tool, so long as it can be hooked onto the rising portions 23a, 23a of the pair of attachment portions 23, 23 of the fishing line holder 100 to attach the fishing line holder 100 to the fishing rod 4. For example, a rubber band, rubber cord, etc. may be used as the auxiliary tool.

Referring to Figures 5 to 8, first, the fishing line holder 100 is placed on the outer periphery of the fishing rod 4. Next, one end of the O-ring 3 is hooked onto one of the rising portions 23a (see Figure 3) of the pair of mounting portions 23, 23 of the fishing line holder 100. Next, the O-ring is stretched and wrapped around the fishing rod 4, and the other end of the O-ring 3 is hooked onto the other rising portion 23a of the pair of mounting portions 23, 23 of the fishing line holder 100. This attaches the fishing line holder 100 to the fishing rod 4.

Next, for example, the fishing line 5 attached to the fishing rod 4 and having the fishing hook 7 and sinker 6 attached thereto is pulled appropriately and moved along the first clamping surface Fp1 of the first clamping member 1 of the fishing line holder 100 or the second clamping surface Fp2 of the second clamping member 2 toward the shaft 12 of the pressure connection structure 10. In this case, the fishing line 5 may be wound around the shaft 12 of the fishing line holder 100. As described above, if a short cylindrical portion without a male thread is formed at the base of the shaft 12, the fishing line 5 is prevented from being cut into the valley of the male thread when it is wound around the base of the shaft 12.

This causes the fishing line 5 to be secured to the fishing line fastener 100. Next, the fishing hook 7 is inserted into the spherical end surface of the first clamping member 1 and secured therein.

This prevents the fishing line 5 from coming off the fishing rod 4 when you are taking a break from fishing. As a result, for example, the fishing line can be prevented from getting tangled with surrounding objects when moving to a different fishing spot.

(Embodiment 2)
In the second embodiment, the first clamping member and the second clamping member 2 of the fishing line holder 100 according to the first embodiment are provided to a user as a fishing line holder set in an uncoupled state.

According to this embodiment 2, the user can obtain the same effect as in embodiment 1 by pressurizing and joining the first clamping member 1 and the second clamping member 2.

(Embodiment 3)
The third embodiment of the present invention illustrates an embodiment in which the fishing line holder 100 of the first embodiment is configured as a line stopper. Specifically, the fishing line holder 300 of the third embodiment differs from the fishing line holder 100 of the first embodiment in the following respects, but is otherwise similar to the fishing line holder 100 of the first embodiment. These differences will be described below.

9 is a cross-sectional view showing an example of the configuration of the fishing line holder 300 according to the third embodiment of the present invention. Referring to FIG. 9, in the fishing line holder 300 of the third embodiment, the second clamping member 2 includes the main body 21 and the hole 22, but does not include the mounting portion 23 of the fishing line holder 100 of the first embodiment. In addition, the overall shape of the main body 11 of the first clamping member and the overall shape of the main body 21 of the second clamping member 2 are formed in a hemispherical shape. The base end surface of the main body 11 of the first clamping member 1 is formed with a first clamping surface Fp1 including a first contact surface Fc1 and a first inclined surface Fs1 similar to the first clamping surface Fp1 of the main body 11 of the first clamping member 1 of the fishing line holder 100 of the first embodiment. The shaft portion 12 of the first clamping member 1 is formed in the same manner as the shaft portion 12 of the first clamping member 1 of the first embodiment, but the base portion 12a of the shaft portion 12 is formed in a short cylindrical shape without a male thread. This short cylindrical base 12a has a diameter smaller than the diameter of the male thread root and a length equivalent to one or two turns of the male thread. This prevents the fishing line 5 from getting caught in the male thread root when the fishing line 5 is wound around the base 12a of the shaft 12.

A second clamping surface Fp2 configured similarly to the first clamping surface Fp1 of the main body 11 of the first clamping member 1 is formed on the base end surface of the second clamping member 2. That is, the second clamping surface Fp2 includes a second contact surface Fc2 formed similarly to the first contact surface Fc1 and a second sloping surface Fs2 formed similarly to the first sloping surface Fs1. The hole 22 of the second clamping member is formed similarly to the hole 22 of the first clamping member 1 of the fishing line holder 100 of the first embodiment.

At least one of the tip surface Ff1 of the first clamping member 1 and the tip surface Ff2 of the second clamping member 2 may have a portion (not shown) that serves as a handhold when screwing the first clamping member 1 into the second clamping member 2. Examples of such handholds include a rib of an appropriate shape (e.g., a cross shape), a matte finish, etc. Also, at least one of the first clamping member 1 and the second clamping member 2 may be formed into a polygonal pyramid shape, and the first clamping surface Fp1 or the second clamping surface Fp2 may be formed on at least one of the base end surfaces. In this case, the ridge of the polygonal pyramid on the tip surface Ff1 or Ff2 serves as the handhold.

[Action and Effect]
The fishing line holder 300 of the third embodiment configured as described above differs from the fishing line holder 100 of the first embodiment only in that it does not have the pair of mounting portions 23, 23 of the fishing line holder 100 of the first embodiment. Therefore, the function and effect of the fishing line holder 300 of the third embodiment is the same as the function and effect of the fishing line holder 100 of the first embodiment shown in FIG. 5. 5 and 9, according to the fishing line holder 300 configured as described above, when the fishing line 5 (see FIGS. 5 and 10) is moved along the first clamping surface Fp1 of the first clamping member 1 or the second clamping surface Fp2 of the second clamping member 2 toward the shaft portion 12 of the pressure coupling structure 10 with the fishing line 5 taut, the fishing line 5 is first guided to the first clamping surface Fp1 of the first clamping member 1 or the second clamping surface Fp2 of the second clamping member 2, and then the fishing line 5 is clamped by the first contact surface Fc1 of the first clamping member 1 and the second contact surface Fc2 of the second clamping member 2. In this case, the first contact surface Fc1 of the first clamping member 1 and the second contact surface Fc2 of the second clamping member 2 are in surface contact with each other and pressurized, and both the first contact surface Fc1 and the second contact surface Fc2 are elastically deformed in their normal directions, so that a sufficient clamping force acts on the fishing line 5 even if the fishing line 5 is thin. Furthermore, since the fishing line holder 300 is entirely spherical, it has an excellent design.

[how to use]
Since the method of using a line stopper is well known, the method of using the fishing line holder 300 will be briefly described below. Fig. 10 is an external view showing the state in which a fishing line 5 is held by the fishing line holder 300 of Fig. 9. Referring to Figs. 9 and 10, in fishing, a suitable position of the fishing line 5 that is unwound from a reel is moved, with an appropriate tension applied, along the first clamping surface Fp1 of the first clamping member 1 or the second clamping surface Fp2 of the second clamping member 2 of the fishing line holder 300 toward the shaft 12 of the pressure coupling structure 10. In this case, the fishing line 5 may be wound around the shaft 12 of the fishing line holder 300.

This causes the fishing line 5 to be secured to the fishing line fastener 300. Next, the reel is operated to wind the fishing line 5 until the fishing line fastener 300 abuts against the fishing line 5 outlet of the reel. When the fishing line fastener 300 abuts against the fishing line 5 outlet of the reel, the fishing line 5 is locked. This makes it possible to prevent the fishing line 5 from getting tangled with surrounding objects, for example, when moving to a different fishing spot.

(Embodiment 4)
In the fourth embodiment, the first clamping member 1 and the second clamping member 2 of the fishing line holder 300 according to the third embodiment are provided to a user as a fishing line holder set in an uncoupled state.

According to this embodiment 4, the user can obtain the same effect as in embodiment 3 by pressurizing and joining the first clamping member 1 and the second clamping member 2.

Other Embodiments
In any of the first to fourth embodiments, the first clamping member 1 may be provided with the hole portion 22 , and the second clamping member 2 may be provided with the shaft portion 12 .

In any of the first to fourth embodiments, or in other embodiments, the outer periphery of the shaft portion 12 and the inner periphery of the hole portion 22 may be smooth, and the first clamping member and the second clamping member 2 may be press-fitted into the hole portion 22 so that the hole portion 22 and the shaft portion 12 fit together.

The fishing line holder 100 of embodiment 1 or embodiment 2 may be used as a line stopper.

A pair of attachment portions 23, 23 of the fishing line holder 100 of embodiment 1 may be provided on the tip surface Ff1 of the first clamping member 1 or the tip surface Ff2 of the second clamping member 2 of the fishing line holder 300 of embodiment 3 or embodiment 4. This allows the fishing line holder 300 to be attached to the fishing rod 4 for use.

In any of the first to fourth embodiments, if the fishing line 5 is thick, the degree of screwing between the first clamping member 1 and the second clamping member 2 may be adjusted to provide a gap between the first contact surface Fc1 and the second contact surface Fc2. This allows the thick fishing line to be appropriately fastened to the fishing line fastener 100, 300. In this case, since the hole 22 and the shaft 12 are elastic, the gap between the first contact surface Fc1 and the second contact surface Fc2 is appropriately maintained.

Many modifications and other embodiments will be apparent to those skilled in the art from the above description. Therefore, the above description should be interpreted as illustrative only.

The fishing line fastener and fishing line fastener set of the present invention are useful as fishing line fasteners and fishing line fastener sets that exert sufficient fastening force on the fishing line even when the fishing line is thin.
