Description

The present invention relates to a fishing line guide for guiding a fishing line and a fishing rod provided with the guide.

The fishing line guide for guiding the fishing line is generally provided with a guide frame formed by punching out a metal plate and a guide ring attached to a hole of the guide frame to guide the fishing line. However, since the guide frame is formed by punching out a metal plate, there is a limit to reducing the weight while ensuring the strength.

Therefore, the present inventors have studied that the guide frame is made of a metal wire (see Patent Document 1 below).

Japanese Unexamined Patent Publication No. 2017-46640

An object of the present invention is to provide a fishing line guide capable of reducing the weight, suppressing the occurrence of thread entanglement, and improving the holding force of the guide ring, and a fishing rod provided with the fishing line guide.

The present invention has been made to solve the above problems, and the fishing line guide according to the present invention is a fishing line guide provided with a guide ring for guiding the fishing line and a guide frame for holding the guide ring. The guide frame has a frame portion that abuts on a predetermined angle region on the entire circumference of the outer peripheral surface of the guide ring, a mounting portion for mounting on the rod body, and both ends and mounting portions in the circumferential direction of the frame portion. It is provided with a pair of left and right support legs to be connected, and at least the frame portion of the guide frame and the upper part of both the left and right support legs are composed of one metal wire, and the frame portion of the guide frame and both support legs are provided. An inner curved portion having a shape curved inward in the left-right direction is formed at both the left and right boundary portions, and the section between the inner curved portion of the guide frame and the lower end portion of the support leg is formed in the front view from the front side. It is characterized by having a shape that bulges outward in the left-right direction with respect to a straight line connecting the inner curved portion and the lower end portion of the support leg portion. The tip side of the rod is the front side, and the bottom side of the rod is the rear side. Further, the mounting portion side is the lower side, the guide ring side is the upper side, and the direction orthogonal to the vertical direction is the left-right direction when viewed from the front side.

An inner curved portion having a shape curved inward in the left-right direction is formed at both the left and right boundary portions of the frame portion of the guide frame and both supporting legs in the fishing line guide having the above configuration. That is, the guide frame is enclosed inward in the left-right direction at a position where the frame portion of the guide frame is separated from the guide ring. Since the constricted portion is formed in the guide frame at the position below the guide ring in this way, the guide ring can be firmly held by the frame portion of the guide frame. Then, by forming a shape that bulges outward in the left-right direction in the section between the inner curved portion of the guide frame and the lower end portion of the support leg portion, the shape extends linearly from the inner curved portion toward the lower end portion of the support leg portion. In comparison with, the fishing line is less likely to get entangled with the support leg.

In particular, the section between the inner curved portion and the lower end portion of the support leg is an upper inclined portion that gradually separates from the straight line to the lateral side in the left-right direction from the inner curved portion to the inflection point in the middle in the front view. It is preferably composed of a lower inclined portion that gradually approaches the straight line from the inflection point to the lower end portion of the support leg portion, and the inflection point is preferably formed at a position closer to the lower end portion of the support leg portion. By forming the inflection point of the bulging shape at a position closer to the lower end of the support leg, the fishing line can be guided more smoothly to the outside in the left-right direction, and thread entanglement is less likely to occur.

Further, a spacer is formed on the outer peripheral surface of the guide ring, and the frame portion of the guide frame is engaged with the peripheral groove to fill the peripheral groove in the non-holding region of the guide ring which is not held by the frame portion. It is preferable to have it. If a peripheral groove is formed on the outer peripheral surface of the guide ring and the peripheral groove and the frame portion of the guide frame are engaged with each other, the holding force of the guide ring by the frame portion of the guide frame can be increased. .. On the other hand, since the peripheral groove of the guide ring is exposed in the non-holding region of the guide ring, the contact resistance between the outer peripheral surface of the non-holding region of the guide ring and the fishing line is reduced by filling the peripheral groove with a spacer. Can be made to.

Further, it is preferable that both ends of the spacer in the circumferential direction are close to and separated from the inside of the left and right inner curved portions of the guide frame. In this way, both ends of the spacer in the circumferential direction are close to the inside of the left and right inner curved portions of the guide frame, so that substantially the entire circumferential groove in the non-holding region of the guide ring is filled with the spacer. Can be done. Then, both ends in the circumferential direction of the spacer are separated from each other without abutting against the left and right inner curved portions of the guide frame, so that the spacer stretches the left and right inner curved portions from the inside toward the outside. There is no pressing. Therefore, the guide ring can be firmly held by the guide frame.

Further, the spacer is adhesively fixed to the guide ring, and among the engaging portions of the spacer engaged with the peripheral groove of the guide ring, the front portion and the rear portion abut on the peripheral groove of the guide ring, and the intermediate portion in the front-rear direction. Is preferably separated from the peripheral groove of the guide ring, and an adhesive pool is formed between the peripheral groove of the guide ring and the intermediate portion in the front-rear direction of the engaging portion of the spacer. As described above, in a configuration in which the spacer and the left and right inner curved portions of the guide frame are not in contact with each other, it is necessary to firmly bond and fix the spacer to the guide ring, but it is necessary to prevent the adhesive from squeezing out. Therefore, by forming an adhesive pool between the peripheral groove of the guide ring and the intermediate portion in the front-rear direction of the engagement portion of the spacer, the spacer can be firmly adhered to the guide ring and the adhesive can be prevented from squeezing out. ..

Further, the fishing rod according to the present invention is provided with such a fishing line guide.

As described above, the inner curved portion is formed at the boundary between the frame portion and the support leg portion of the guide frame, and the section between the inner curved portion and the lower end portion of the support leg portion bulges outward. Therefore, the weight of the fishing line guide can be reduced, the occurrence of thread entanglement can be suppressed, and the holding force of the guide ring can be improved.

(Width direction).

<Guide ring 2>
The guide ring 2 has a circular ring shape as shown in FIG. 1, but may have an elliptical shape, an oval shape, or the like. The guide ring 2 is made of various hard materials having excellent wear resistance, and of course, it may be a ceramic typified by, for example, SiC (silicon carbide), but in this embodiment, it is made of titanium. Titanium alloy is preferable as titanium. Titanium alloy is a mixture of α phase and β phase, and is mainly α phase, near α type with β phase remaining in part (α alloy with a small amount of β stabilizing element added). α + β type and β type are preferable. In particular, a β-type titanium alloy is preferable, cold workability is good, and the strength of the member can be easily secured. Examples of the near α type include Ti-8Al-1Mo-1V and Ti-6Al-2Nb-1Ta-0.8Mo. The α + β type has a larger amount of β phase remaining than the near α type, and is, for example, Ti-3Al-2.5V, Ti-6Al-4V, or the like. The β type is also called a metastable β type, and has more β stabilizing elements and less α stabilizing elements than the α + β type. In the β type, the α phase is dispersed in the residual β phase with fine particles, and therefore, in the β type as well, the α phase and the β phase are present in a mottled pattern on the surface. .. Examples of the β type include Ti-15V-3Cr-3Sn-3Al, Ti-3Al-8V-6Cr-4Zr-4Mo, Ti-10V-2Fe-3Al and the like, but in particular, for cold workability. Ti-15V-3Cr-3Sn-3Al is preferable because it is excellent.

The guide ring 2 has a thread insertion hole through which the fishing line is inserted, and the fishing line slides on the inner peripheral surface 2a of the guide ring 2 to directly guide the fishing line. As shown in FIGS. 6, 7 and 9 (b), the inner peripheral surface 2a of the guide ring 2 is a curved surface curved in the front-rear direction so as to be inwardly convex (center-side convex) in a cross-sectional view. The outer peripheral surface 2b of the guide ring 2 is also a curved surface curved in the front-rear direction so as to be inwardly convex (convex on the center side) in a cross-sectional view. That is, the guide ring 2 is curved in an arc shape so as to be convex on the center side and a convex inner peripheral surface 2a curved in an arc shape so as to be convex on the center side in a cross-sectional view cut in the direction of the center line 50. It has a concave outer peripheral surface 2b. The inner peripheral surface 2a and the outer peripheral surface 2b of the guide ring 2 have shapes corresponding to each other. Further, the guide ring 2 is made of a bent thin metal plate, and the front surface and the back surface of the metal plate are an inner peripheral surface 2a and an outer peripheral surface 2b, respectively.

Specifically, since the guide ring 2 is curved in an arc shape so that the thin metal plate is convex toward the center, both ends 22, 23 in the direction of the center line 50, that is, the front and rear ends 22, 23 each project radially outward in an annular shape. Therefore, on the outer peripheral surface 2b of the guide ring 2, a peripheral groove 20 having an arcuate cross-sectional view is formed between the front and rear ends 22 and 23 over the entire circumference. The diameters of the front and rear ends 22 and 23 are all larger than the inner diameter of the frame portion 30 of the guide frame 3 (the diameter at the apex, which is the smallest diameter portion of the inner peripheral surface of the frame portion 30). The diameters of the front and rear ends 22 and 23 may be the same as each other, but it is preferable that the diameter of one is smaller than the diameter of the other, and in the present embodiment, the diameter of the front end 22 is larger than the diameter of the rear end 23. Is also small.

As will be described later, the frame portion 30 of the guide frame 3 and the spacer 4 engage with the peripheral groove 20 of the outer peripheral surface 2b of the guide ring 2. The guide frame 3 is made of a metal wire having a circular cross section, and an angle range exceeding 180 degrees of the entire circumference of the circular cross section engages with the peripheral groove 20 of the outer peripheral surface 2b of the guide ring 2. As shown in FIG. 9B, the radial thickness G1 of the guide ring 2 is smaller than the dimension G2 (length) along the direction of the center line 50 of the guide ring 2.

The guide ring 2 is formed by pressing a metal plate into a predetermined shape. As shown in FIG. 8, for example, a metal plate made of a titanium alloy is punched into a donut shape, and the punched donut-shaped metal plate 21 is indicated by an arrow from one of the front surface and the back surface as shown in FIG. 9A. At the same time as being pressed into a tubular shape, one end of the tubular metal plate 21 is curved outward in the radial direction in a flange shape to form the end portion 23. Next, as shown in FIG. 9B, the cylindrical metal plate 21 is further pressed from the other side, which is the opposite side, as shown by an arrow, and the other end portion is also radially outward like the one end portion. The end portion 22 is formed by being curved in a flange shape, and the guide ring 2 is formed as a cross-sectional shape having a visual arc shape in which the cross-sectional shape of the tubular metal plate 21 is curved to be convex toward the center as a whole.

The magnitude of the curvature of the other end of the metal plate 21 is smaller than that of the one end, that is, the magnitude of the curvature of the other end of the guide ring 2 is smaller than that of the one end. Therefore, the outer diameter of the guide ring 2 is larger at one end than at the other end. The both end portions 22 and 23 of the guide ring 2 thus formed are annular ends protruding outward in the radial direction, respectively, and the peripheral groove 20 is formed between the both end portions 22 and 23. The guide frame 3 and the spacer 4 are engaged with the guide frame 3.

The outer peripheral surface 2b of the guide ring 2 and the frame portion 30 of the guide frame 3 may be in surface contact or point contact in a cross-sectional view cut in the radial direction. The guide frame 3 is a metal wire having a circular cross section, but when the outer peripheral surface 2b of the guide ring 2 and the guide frame 3 make point contact, a space is provided in the front-rear direction (circumferential direction of the circular cross section of the metal wire) instead of one point. It is preferable to make contact at a plurality of points, and it is more preferable to make contact at two or three points.

<Guide frame 3>
The guide frame 3 stands up from the mounting portion 32 for mounting on the outer peripheral surface of the rod body 5 and upward from the front end portion of the mounting portion 32, that is, radially outward from the rod body 5, and the rod body 5 It is provided with a frame main body portion that holds the guide ring 2 at a position separated from the guide ring 2. The frame main body portion includes an upper frame portion 30 and a lower support leg portion 31, the frame portion 30 holds the guide ring 2, and the support leg portion 31 connects the frame portion 30 and the mounting portion 32.

In the present embodiment, the entire guide frame 3 is made of a metal wire rod. The guide frame 3 is composed of a hollow portion and a solid portion. The guide frame 3 is composed of two members, and is configured by joining and integrating a hollow body 34 made of a hollow metal wire and a solid substance 35 made of a solid metal wire. That is, the guide frame 3 has a hybrid configuration in which the hollow body 34 and the medium substance 35 are joined to each other and integrated. The hollow body 34 is made of one hollow metal wire, and the solid body 35 is made of one solid metal wire. Both ends 34a of the hollow metal wire and both ends 35a of the solid metal wire are joined and integrated over a predetermined length to form the guide frame 3. Therefore, the guide frame 3 is composed of two metal wires and has an endless shape as a whole.

The guide frame 3 has two metal wire rod ends 34a and 35a joined to each other, and has two wire rod joint portions 36 on the left and right. The solid metal wire has an outer diameter corresponding to the inner diameter of the hollow metal wire, and both ends 35a of the solid metal wire are inserted into both ends 34a of the hollow metal wire and joined to each other. There is. The joining method may be adhesion or welding. The wire joint portion 36 is located above the boundary portion 33 between the attachment portion 32 and the frame main body portion, and therefore, the wire rod joint portion 36 is located above the boundary portion 33 between the attachment portion 32 and the support leg portion 31. positioned. The wire rod joint portion 36 is provided particularly at the lower portion of the support leg portion 31, but in the present embodiment, the wire rod joint portion 36 is located at the lowermost portion of the support leg portion 31. A wire rod joint portion 36 having a predetermined length is formed by inserting both end portions 35a of the solid metal wire rod into the inside of both end portions 34a of the hollow metal wire rod over a predetermined length.

As shown in FIG. 6, the frame main body portion stands up at a predetermined angle on the mounting portion 32. The center line 50 of the guide ring 2 may be parallel to the center line of the rod body 5, or may be tilted forward rather than parallel to the center line of the rod body 5. Therefore, the frame main body portion may stand up at a right angle to the upper side with respect to the mounting portion 32, or may stand up in a forward leaning posture. In the present embodiment, the center line 50 of the guide ring 2 is not parallel to the center line of the rod body 5 but is slightly tilted to the front side. Therefore, the frame main body portion stands up so as to be in a slightly forward leaning posture. Note that FIGS. 3, 4 and 10 are viewed from the direction of the center line 50 of the guide ring 2.

Of the guide frame 3, the entire mounting portion 32 and the boundary portion 33 between the mounting portion 32 and the frame main body portion are composed of only the middle entity 35. Most of the frame main body except the lowermost portion is composed of only the hollow body 34, and the lowermost portion of the frame main body portion is composed of the wire rod joint portion 36 formed by the middle substance 35 and the hollow body 34. .. The simple substance of the hollow body 34 is shown in FIG. The hollow body 34 is formed by bending one hollow metal wire into a U shape so as to form substantially the entire frame portion 30 and the pair of left and right support legs 31, and the hollow metal wire is formed. Both ends 34a of the above are arranged side by side and are in contact with each other or in close proximity to each other. The left and right support leg portions 31 are closest to each other in the left-right direction at the lower end portions thereof, and that portion is the closest point. In the present embodiment, the lower ends of the support legs 31 are in close contact with each other or close to each other via a slight gap. Reference numeral P in FIG. 10 is a point where the lower ends of the left and right support legs 31 are in contact with each other or are close to each other, and is at least the closest point, and this point P is hereinafter simply referred to as the closest point P. The details of the medium entity 35 will be described later.

The metal wire is made of, for example, a titanium alloy, stainless steel, or an aluminum alloy. Among them, titanium alloy is particularly preferable from the viewpoint of weight reduction. The details of the titanium alloy are the same as those of the guide ring 2, and the β-type titanium alloy is preferable because it has good cold workability and the strength of the member can be easily secured. The hollow metal wire and the solid metal wire may be made of different materials or the same material, and as an example, both are made of β-type titanium alloy to reduce the weight. be able to. The metal wire has a circular cross-sectional shape. The outer diameter of the hollow metal wire, that is, the wire diameter of the metal wire is, for example, 0.3 to 6 mm, preferably 1 to 3 mm. As described above, the outer diameter of the solid metal wire preferably corresponds to the inner diameter of the hollow metal wire.

<Frame part 30>
The frame portion 30 is a portion for holding the guide ring 2 inside the frame portion 30, and constitutes a region on the tip end side of the frame main body portion, and is formed in an arc shape having a predetermined central angle θ. The frame portion 30 is formed in a C shape that opens downward by bending a hollow metal wire rod along the outer peripheral surface of the guide ring 2, and therefore, the frame portion 30 is completely hollow. It is a shape. The frame portion 30 has a size and shape corresponding to the guide ring 2. The frame portion 30 abuts only in a predetermined angle range of the entire circumference of the guide ring 2 and supports the outer peripheral surface of the guide ring 2 only in the predetermined angle range. The frame portion 30 orbits and holds a predetermined angle range of the guide ring 2, but its central angle θ exceeds 180 degrees.

FIG. 10 shows a virtual circle 52 having an extended inner peripheral surface of the frame portion 30 as a two-dot chain line. The virtual circle 52 is a circle when the inner peripheral surface of the frame portion 30 is extended to 360 degrees in the circumferential direction and the inner peripheral surface of the 360 degrees is viewed in the direction of the center line 50 of the guide ring 2. The diameter of the virtual circle 52 is the inner diameter of the frame portion 30 (the diameter at the apex, which is the smallest diameter portion of the inner peripheral surface of the frame portion 30). When the tangents are drawn from the closest point P where the lower ends of the support legs 31 are in contact with each other toward the virtual circle 52 when viewed from the front, the contact points where the two tangents are in contact with the virtual circle 52 are designated by reference numeral 54. It is shown by. The central angle θ of the frame portion 30 is larger than the upper central angle α between the contacts 54. If they are not in contact with each other at the closest point P, a tangent line is drawn from each of the left and right closest points P separated to the left and right.

<Support leg 31>
The support leg portion 31 is located between the frame portion 30 and the mounting portion 32 and connects the frame portion 30 and the mounting portion 32. The support leg portion 31 has a two-legged structure in which two legs are arranged side by side in a front view and has a symmetrical shape, and extends downward from both ends of the frame portion 30. The left and right support legs 31 are closest to each other at the lower end thereof and are in contact with each other in the present embodiment, and are gradually spread to the left and right from the closest point P toward both ends of the frame portion 30 and separated from each other. go. Therefore, the left and right support legs 31 are V-shaped as a whole in the front view. The distance between the upper ends of the pair of left and right support legs 31 in the left-right direction is smaller than the diameter of the virtual circle 52.

An inner curved portion 37 curved inward in the left-right direction is formed between both ends of the frame portion 30 and the left and right support leg portions 31, respectively. When viewed from the front side, the section from the inner curved portion 37 of the guide frame 3 to the lower end portion of the support leg portion 31 has a shape that bulges outward in the left-right direction. In FIG. 10, a virtual straight line 53 connecting the top of the inner surface of the inner curved portion 37 and the closest point P of the lower end of the support leg portion 31 is shown by a two-dot chain line on each of the left and right sides. The section from the inner curved portion 37 of the guide frame 3 to the lower end portion of the support leg portion 31 has a shape that bulges outward in the left-right direction with respect to the virtual straight line 53. When the closest points P are not in contact with each other, a virtual straight line 53 is used to connect the left and right closest points P separated from each other to the top of the inner surface of the inner curved portion 37.

Specifically, the section from the inner curved portion 37 to the lower end portion of the support leg portion 31 gradually moves outward from the virtual straight line 53 from the inner curved portion 37 to the inflection point 38 in the middle in the front view. After that, the virtual straight line 53 is gradually approached from the inflection point 38 to the lower end of the support leg portion 31. Therefore, the section from the inner curved portion 37 to the lower end portion of the support leg portion 31 is from the upper inclined portion 39a from the inner curved portion 37 to the inflection point 38 and from the inflection point 38 to the lower end portion of the support leg portion 31. It is composed of a lower inclined portion 39b. The vicinity of the inflection point 38 has a shape curved outward in the left-right direction. In front view, the upper inclined portion 39a extends linearly. Further, the lower inclined portion 39b also extends linearly in the front view. The inflection point 38 is located near the lower end of the support leg portion 31. That is, the inflection point 38 is located in the lower half section of the section from the inner curved portion 37 to the lower end portion of the support leg portion 31. In front view, the inclination angle of the upper inclined portion 39a with respect to the center line extending in the vertical direction of the guide frame 3 is smaller than the inclination angle of the lower inclined portion 39b with respect to the center line extending in the vertical direction of the guide frame 3. Therefore, the degree of left-right spread of the left and right support leg portions 31 is relatively steep in the section of the lower inclined portion 39b, and relatively gentle in the section of the upper inclined portion 39a.

<Mounting part 32>
The solid substance 35 is composed of a single solid metal wire. One solid metal wire is folded in half to the left and right at the intermediate point, the folded portion is located at the rear end, and both ends 35a of the solid metal wire face forward and upward. .. Therefore, the medium substance 35 is composed of a pair of left and right linear portions in a folded state. One solid metal wire is folded back to the left and right at the rear end of the mounting portion 32. In the mounting portion 32, a pair of left and right linear portions are arranged in parallel on the left and right, and are in contact with each other in the present embodiment. However, in the mounting portion 32, the pair of left and right linear portions may be slightly separated from each other to the left and right. The pair of left and right linear portions extend from the boundary portion 33 between the frame main body portion and the mounting portion 32 in a V-shape to the left and right while being inclined upward and forward to a predetermined length. That is, the middle entity 35 is composed of a parallel portion in which a pair of left and right linear portions are in a parallel state, and an upward extending portion extending upward from the front end portion of the parallel portion in a V shape. The portion becomes the mounting portion 32, and at least the upper portion of the upward extending portion is inserted into both end portions 34a of the hollow body 34 to form a pair of left and right joining insertion portions for forming the wire rod joining portion 36. In the present embodiment, substantially the entire upward extending portion is a pair of left and right joining insertion portions, and is inserted into both end portions 34a of the hollow body 34. It is preferable that a concave surface portion (not shown) curved upward in the left-right direction along the outer peripheral surface of the rod body 5 is formed on the substantially overall length of the lower surface of the mounting portion 32.

<Spacer 4>
As described above, the frame portion 30 has a C-shape that opens downward. The frame portion 30 abuts and supports only the upper predetermined angle region of the entire circumference of the outer peripheral surface 2b of the guide ring 2. Therefore, the lower predetermined angle region of the outer peripheral surface 2b of the guide ring 2 does not abut on the guide frame 3. The lower predetermined angle region is a non-holding region in which the guide ring 2 is not held by the frame portion 30, and a non-circular portion of the entire circumference of the guide ring 2 in which the frame portion 30 of the guide frame 3 does not rotate. Is. A spacer 4 is provided in the non-holding region.

As shown in FIG. 11A, the inner surface 40 of the spacer 4 is an arcuate rod-shaped body having a radius corresponding to the outer peripheral surface 2b of the guide ring 2 and having a central angle corresponding to the non-holding region. As shown in FIG. 11B, the inner surface 40 of the spacer 4 is along the direction of the center line 50 of the guide ring 2, and the outer surface 41 of the spacer 4 is also along the direction of the center line 50 of the guide ring 2. The 40 and the outer surface 41 are parallel to each other. The front and rear side surfaces 42 of the spacer 4 are bulging and curved toward the front side and the rear side.

As shown in FIG. 7, the spacer 4 is engaged with the peripheral groove 20 of the non-holding region of the guide ring 2 so as to fill the peripheral groove 20 of the non-holding region of the guide ring 2. Further, the spacer 4 is adhered to the guide ring 2. The spacer 4 slightly protrudes radially outward from the front and rear ends 22 and 23 of the guide ring 2. The amount of protrusion is relatively large on the front side as shown in FIG. 3 and relatively small on the rear side as shown in FIG. The portion of the spacer 4 that is engaged with the peripheral groove 20 of the non-holding region of the guide ring 2 is the engaging portion. The engaging portion of the spacer 4 is composed of a front portion, a rear portion, and an intermediate portion in the front-rear direction. The front portion and the rear portion have an arcuate cross section, and the intermediate portion in the front-rear direction has a linear cross section. The inner surface 40 of the spacer 4 constitutes an intermediate portion in the front-rear direction of the engaging portion, and the inner portion of the front-rear and front-rear side surfaces 42 of the spacer 4 constitutes the front portion and the rear portion of the engaging portion. The inner portion of the front and rear side surfaces 42 of the spacer 4 is in contact with the peripheral groove 20 of the guide ring 2. The inner surface 40 of the spacer 4 is radially outwardly separated from the peripheral groove 20 of the guide ring 2, and there is a streak-like gap extending in the circumferential direction between the peripheral groove 20 of the guide ring 2 and the inner surface 40 of the spacer 4. A certain adhesive pool 43 is formed. The adhesive pool 43 is formed over the entire length of the spacer 4 in the circumferential direction. An adhesive for adhering the spacer 4 to the guide ring 2 can be stored in the adhesive sump 43.

As shown in FIG. 11A, notches 44 are formed on both front and rear side surfaces 42 of both ends 4a in the circumferential direction of the spacer 4, and the notches 44 also serve as adhesive pools. Both ends 4a in the circumferential direction of the spacer 4 are not in contact with the left and right inner curved portions 37 of the guide frame 3, but are close to each other so as to be slightly separated from each other. The distance between both ends 4a in the circumferential direction of the spacer 4 and the left and right inner curved portions 37 of the guide frame 3 is small, preferably 1 mm or less, and more preferably 0.5 mm or less.

The material of the spacer 4 is preferably one having a small specific gravity, and can be, for example, a hard resin or a fiber reinforced resin, and can be formed by injection molding. When the fiber reinforced resin is used, it is particularly preferable to use carbon fiber as the reinforced fiber. The spacer 4 may be made of a metal such as a titanium alloy like the guide frame 3 and the guide ring 2.

The fishing line guide configured as described above is manufactured by adhering the spacer 4 to the guide ring 2 and mounting the guide ring 2 with the spacer 4 on the guide frame 3 so as to be pushed from the rear side to the front side. .. Then, the fishing line guide is attached to the outer peripheral surface of the rod body 5 of the fishing rod. A fishing line guide mounting portion 32 is placed on the rod body 5, and a winding thread (not shown) is wound around the mounting portion 32 and the rod body 5 to bind the fishing line guide to the rod body 5. Further, an adhesive synthetic resin (adhesive) is applied to the wound portion of the winding yarn and hardened.

In the fishing line guide configured as described above, since the inner curved portion 37 is formed at the boundary between the frame portion 30 of the guide frame 3 and the support leg portion 31, the guide is guided by the frame portion 30 of the guide frame 3. The ring 2 can be held firmly. In particular, since the central angle of the frame portion 30 exceeds 180 degrees, a large holding force can be obtained, and the guide ring 2 can be prevented from coming off from the guide frame 3. Further, since the section between the inner curved portion 37 and the lower end portion of the support leg portion 31 has a shape that bulges outward, it is possible to prevent the occurrence of thread entanglement in which the fishing line is entangled with the support leg portion 31 of the guide frame 3. be able to. In particular, since the inflection point 38 that bulges outward is located near the lower end of the support leg portion 31, the fishing line that comes into contact with the lower outer surface of the support leg portion 31 of the guide frame 3 is smoothly guided outward in the left-right direction. At the same time, it can be released to the upper side, and thread entanglement is less likely to occur.

Further, by forming the inner curved portions 37 on the left and right, the non-holding region of the guide ring 2 can be reduced, and the central angle of the spacer 4 can be reduced even in the configuration using the spacer 4. The spacer 4 can be made smaller and lighter. Therefore, the weight of the fishing line guide can be reduced as a whole.

Further, since the spacer 4 fills the peripheral groove 20 in the non-holding region of the guide ring 2, the exposed portion of the outer peripheral surface 2b of the guide ring 2 can be reduced. By filling the peripheral groove 20 of the non-holding region of the guide ring 2 with the spacer 4, the contact resistance between the outer peripheral surface 2b of the non-holding region of the guide ring 2 and the fishing line can be reduced. In particular, since the spacer 4 protrudes radially outward from the guide ring 2, the fishing line is less likely to come into contact with the front and rear ends 22 and 23 of the guide ring 2. Further, even if the spacer 4 protrudes radially outward from the guide ring 2, the amount of protrusion is small and extends in a streak shape in the circumferential direction. Therefore, when the fishing line guide is viewed from the front side or the rear side, the exposed portion of the spacer 4 is very small and the spacer 4 is inconspicuous. Therefore, an appearance as if only the guide ring 2 is present can be obtained.

Further, the spacer 4 is not configured to connect the left and right support legs 31, but both ends 4a of the spacer 4 in the circumferential direction are close to the inside of the left and right inner curved portions 37 of the guide frame 3, but are separated from each other. .. Since both ends 4a in the circumferential direction of the spacer 4 are close to the inside of the left and right inner curved portions 37 of the guide frame 3, substantially the entire circumferential direction of the peripheral groove 20 in the non-holding region of the guide ring 2 is covered by the spacer 4. Can be filled. On the other hand, since both ends 4a of the spacer 4 in the circumferential direction are slightly separated inward from the left and right inner curved portions 37 of the guide frame 3, the spacer 4 extends outward so as to stretch the left and right inner curved portions 37 from the inside. There is no need to push it toward it. Therefore, the guide ring 2 can be securely held by the frame portion 30 of the guide frame 3 so as to be narrowly held from the left and right.

On the other hand, since a streak-shaped adhesive pool 43 extending over the entire length in the circumferential direction of the spacer 4 is formed between the peripheral groove 20 of the guide ring 2 and the inner surface 40 of the spacer 4, the spacer 43 is formed by the adhesive pool 43. 4 can be firmly adhered to the guide ring 2. In addition, it is possible to prevent the adhesive from squeezing out. Since notches 44 are also formed at both ends 4a in the circumferential direction of the spacer 4 and the notches 44 can be used as an adhesive reservoir, the both ends 4a in the circumferential direction of the spacer 4 can be used as the guide ring 2 or the frame portion. It can be securely adhered and fixed to 30, and the adhesive can be prevented from squeezing out at both ends 4a in the circumferential direction of the spacer 4.

Although the spacer 4 is used in this embodiment, the spacer 4 may not be used. For example, the peripheral groove 20 in the non-holding region of the guide ring 2 may be filled with a filler. A resin may be used as a filler and it may be poured into the peripheral groove 20 to be cured.

Further, although the guide frame 3 has a hybrid configuration consisting of a hollow body 34 and a medium entity 35, the guide frame 3 has a configuration consisting of only the hollow body 34, or the guide frame 3 has a configuration consisting of only the medium entity 35. There may be. That is, the entire guide frame 3 may be composed of a hollow metal wire, or the entire guide frame 3 may be composed of a solid metal wire. Further, a part of the guide frame 3 may have a structure other than the metal wire rod.
