Description

The present invention relates to a fishing line guide which is mounted on a fishing rod and guides a fishing line, and more particularly to a fishing line guide which is characterized in that a guide ring through which the fishing line is inserted and a frame are fixed.

Generally, a fishing line guide includes a frame mounted on the outer peripheral surface of a fishing rod, and a guide ring fixed to the frame and through which the fishing line is actually inserted. A ring holding portion for holding the guide ring and a fixing portion for mounting on the outer surface of the fishing rod are integrally formed on the frame.

The guide ring held by the ring holding portion is generally formed of hard metal, ceramics, or the like, and the guide ring is attached to the ring holding portion by, for example, as disclosed in Patent Document 1, This is performed by manually press-fitting the guide ring into the holding hole, or, as disclosed in Patent Document 2, along the inner wall surface of the holding hole (ring mounting hole) of the ring holding portion along the circumferential direction of the wall surface. This is performed by forming a spiral groove by inserting the guide ring into the holding hole of the ring holding portion with the adhesive applied to the spiral groove.

Actual opening 2016-149993 JP-A-2018-007598

However, as disclosed in Patent Document 1, when the guide ring is press-fitted into the holding hole of the ring holding portion, the guide ring should be press-fitted into the holding hole due to a dimensional error in manufacturing the guide ring. The guide ring attached to the holding hole may come off.

On the other hand, as disclosed in Patent Document 2, when the adhesive is applied to the spiral groove of the holding hole of the ring holding portion and the guide ring is fitted into the holding hole, the spiral groove does not remove the adhesive. Since it is not something that can be stored sufficiently, if the amount of adhesive applied is increased to firmly adhere the guide ring to the ring holding part, the adhesive will stick out from the ring holding part and stick out. New post-treatment such as wiping off the adhesive is required. Further, if the adhesive that has run off is solidified while remaining, the solidified portion may interfere with the subsequent insertion of the fishing line. Alternatively, when the viscosity of the adhesive applied to the spiral groove is high, it is difficult to completely fill the spiral groove with the adhesive, and the adhesive force of the guide ring to the ring holding portion is reduced. In some cases. Further, in that case, if the guide ring is small, the center of the guide ring may be displaced from the center of the holding hole of the ring holding portion.

The present invention has been made based on the above-mentioned problems, and can firmly and accurately fix the guide ring to the ring holding portion without being affected by a dimensional error of the guide ring and without an adhesive. An object of the present invention is to provide a fishing line guide and a manufacturing method thereof.

In order to solve the above-mentioned problems, the present invention holds a frame formed by a prepreg formed by impregnating a reinforcing resin with a synthetic resin and attached to an outer peripheral surface of a fishing rod, and a ring holding portion of the frame. And a guide ring through which a fishing line is inserted, wherein the reinforcing fiber is locked and fixed to the guide ring by the flow of the synthetic resin due to a molding pressure when integrally molding the frame and the guide ring. It is characterized in that it has a locking and fixing part formed by.

According to the above configuration, the frame and the guide ring are not press-fitted or adhesively fixed by an adhesive, and the reinforcing fibers are engaged with the guide ring by the flow of the synthetic resin due to the molding pressure when integrally molding the frame and the guide ring. Since it is integrally attached and fixed by the locking and fixing part that is fixed and fixed, the guide ring is firmly attached to the ring holding part without being affected by the dimensional error of the guide ring and without adhesive. Can be fixed accurately.

That is, according to the present invention, since it is not necessary to press-fit the guide ring into the ring holding portion, it is possible to avoid the inconvenience of the guide ring being unable to be attached or the guide ring coming off due to a dimensional error in manufacturing the guide ring. Further, according to the present invention, since the adhesive is not involved, it is possible to avoid the protrusion of the adhesive from the ring holding portion and the accompanying wiping process of the adhesive. Further, the solidification of the remaining adhesive does not hinder the insertion of the fishing line, and the adhesive fixing force of the guide ring does not decrease due to defective adhesion. Further, by centering the guide ring during molding, it is possible to avoid the inconvenience that the center of the guide ring deviates from the center of the holding hole of the ring holding portion. As a result, since the press-fitting and the adhesive fixing work can be eliminated, it becomes possible to automate the attachment of the guide ring to the frame.

In the above structure, the guide ring may be made of any material. For example, the guide ring may be made of metal or ceramic. Further, in the above-mentioned configuration, the form of the locking fixing portion, that is, the locking fixing form of the reinforcing fiber to the guide ring accompanying the flow of the synthetic resin may be any form. For example, depending on the shape of the molding, the shape or material of the guide ring, etc., the reinforcing fibers may enter the inside of the guide ring together with the synthetic resin (for example, in the annular groove on the outer circumference of the guide ring). Alternatively, the reinforcing fibers may be mounted on or cut into the outer peripheral edge of the guide ring together with the synthetic resin.

Further, in the above structure, the reinforcing fibers forming the prepreg have a length of 2.0 mm or more longer than the width dimension of the ring holding portion of the frame, for example, 2.0 mm or more longer than the outer diameter of the guide ring in order to enhance the reinforcing effect of the prepreg. It is preferably a long fiber, and at least a fiber extending in a direction (TD) perpendicular to the flow direction (MD) of the synthetic resin is desirable to promote locking and fixing to the guide ring. Moreover, the form of the prepreg is also arbitrary. For example, the prepreg may be a plate-shaped sheet, or a columnar body (for example, solid body) or a tubular body as long as it can form a frame having a predetermined shape. Alternatively, the prepreg itself may directly form the shape of the frame. Such a frame-shaped prepreg can be realized by various molding methods including cutting and sewing.

Further, in the above configuration, it is preferable that the guide ring and the frame are integrally heat-sealed or heat-bonded by press molding. According to this, the strong integral molding of the guide ring and the frame can be effectively realized. Further, in the above configuration, a primer having an adhesive action may be interposed between the frame and the guide ring. According to this, the fixing strength between the guide ring and the frame can be further increased.

Further, in the above configuration, the prepreg may be formed of a laminated body of fiber reinforced resin, and the synthetic resin of the prepreg may be a thermosetting resin or a thermoplastic resin. In this case, the laminate is preferably formed by 3 to 15 layers, and the outermost layer forming the laminate comprises woven layers or fibers extending along the outer circumference of the frame. It is preferably a layer. If the outermost layer is a woven fabric layer, strength and structural stability can be ensured, and if the outermost layer includes fibers extending along the outer periphery of the frame, the fastening and fixing of the reinforcing fibers to the guide ring is promoted. It is possible to contribute to the above and to improve the strength.

The present invention also provides a method for manufacturing a fishing line guide having the characteristics described above.

An embodiment of a fishing line guide according to the present invention will be specifically described below with reference to the accompanying drawings. In the attached drawings, the direction of arrow A in FIG. 1 corresponds to the axial length direction of the fishing rod when the fishing line guide is attached to the fishing rod, and FIG. 3 shows the tip rod side viewed from the original rod side. It has become a figure.

As shown in FIGS. 1 to 3, the fishing line guide 1 includes a frame 3 formed by a fiber-reinforced prepreg (hereinafter, simply referred to as prepreg) in which reinforcing fibers are impregnated with a synthetic resin (a structure of the prepreg, and A detailed manufacturing method of the frame 3 will be described later). The frame 3 includes a fixing portion 5 mounted on the outer surface of a fishing rod (rod tube) 40 (see FIG. 3 ), a ring holding portion 7 to which a guide ring 6 through which a fishing line is inserted is attached and held, and a ring holding portion. It has a supporting leg portion 8 that connects between 7 and the fixed portion 5.

The fixing portion 5 is a portion fixed to the surface of the fishing rod 40 at the lower end of the frame 3, extends in the axial direction in the present embodiment, and the contact surface 5a on the back side thereof is placed on the surface of the fishing rod 40. In this state, it is fixed by thread fastening, adhesion, etc.

The ring holding portion 7 is a portion to which the guide ring 6 is fixed so as to guide the fishing line in a state of being separated from the surface of the fishing rod 40. The ring holding portion 7 is formed with an opening (holding hole) 7a for integrally mounting the guide ring 6, and has a substantially circular outer shape as a whole. Further, the guide ring 6 integrally attached to the opening 7a is formed in an annular shape, and a material having a small sliding resistance on the fishing line guide surface 6a which is the inner peripheral surface thereof, such as titanium, aluminum, SUS, ceramics, or the like. Formed by. The guide ring 6 shown in FIGS. 1 to 3 is made of metal and has an annular groove 6b on its outer peripheral surface. In addition, as described later, such a guide ring 6 is integrally formed with the prepreg in a state where the frame 3 is integrally formed with the prepreg and then positioned at a portion of the prepreg corresponding to the opening 7a of the ring holding portion 7. To be done.

Further, the supporting leg portion 8 is a portion that connects the fixing portion 5 and the ring holding portion 7 so that the guide ring 6 is separated from the surface of the fishing rod.

In addition, at least one or more bent portions are formed on the frame 3. In the present embodiment, the first bent portion 10a is formed at the boundary between the fixed portion 5 and the supporting leg portion 8, and further, on the ring holding portion 7 side of the supporting leg portion 8 more gently than the first bent portion 10a. A second bent portion 10b that is bent is formed. In this case, the boundary portion corresponds to a region that rises from the end portion of the fixing portion 5 that is actually fixed to the outer surface of the fishing rod toward the ring holding portion 7.

Further, as will be described later, the frame 3 is formed by pressing or the like from a prepreg in which bent portions 10a and 10b are formed (which is a plate-like body after heat molding). It is formed to have a predetermined outer shape. In the present embodiment, as shown in FIG. 2, the frame 3 is gradually widened as the supporting leg portion 8 rising from the end portion of the fixed portion 5 via the first bent portion 10a is moved upward, The supporting leg portion 8 is integrally connected to a substantially circular ring holding portion 7 having an opening 7a in which the guide ring 6 is integrally attached. In this case, as shown in the drawing, the supporting leg portion 8 may be formed with an opening (thickening) 8a in order to reduce the weight.

Next, a method of forming the frame 3 having the above-described form will be described. First, the overall manufacturing process will be described.

As described above, the frame 3 is formed by the prepreg in which the reinforcing fiber is impregnated with the synthetic resin. In this case, the prepreg is, for example, configured in a state in which reinforcing fibers such as carbon fibers and glass fibers are aligned in a predetermined direction or in the form of a knitted sheet, and a thermosetting resin (for example, epoxy resin) or It has a structure in which a thermoplastic resin (for example, nylon) is impregnated as a matrix resin.

First, the prepreg as described above is cut into a predetermined shape, and these are laminated so as to form a plurality of layers. The number of prepregs to be superposed (the number of layers) and the configuration of each prepreg are not particularly limited, but as described above, the bent portions 10a and 10b are formed in the frame 3, and the frame 3 is used at the time of use. In consideration of the load applied, the characteristics of the fishing rod to be mounted, the mounting portion, and the like, the type of prepreg and the overlapping condition are arbitrarily adjusted.

The prepreg (preform) thus laminated is set together with the guide ring 6 in the mold 50 for press molding as shown in FIG. The mold 50 of the present embodiment is composed of an upper mold (second mold) 51 and a lower mold (first mold) 52 that are divided into upper and lower molds, and are stacked prepregs (reference numeral 20). (Shown) is set in place on the lower mold 52. In this case, the lower die 52 is provided with a convex portion 52c for fitting and aligning the guide ring 6, and the opening 7a of the ring holding portion 7 is provided around the guide ring 6 fitted in the convex portion 52c. The part of the prepreg 20 corresponding to is positioned. In other words, the prepreg 20 is set in the lower mold 52, and the guide ring 6 is set at the site of the prepreg 20 forming the opening (holding hole) 7a of the ring holding portion 7.

Further, in order to facilitate such positioning and promote the flow of the material accompanying the subsequent press molding, the inside diameter of the opening 7a of the ring holding portion 7 of the prepreg 20 is smaller than the outside diameter of the guide ring 6. It is set to be larger by 1 to 0.5 mm, and as clearly shown in FIG. 8, the lower die 52 has an annular step portion 52d for holding the outer peripheral edge of the guide ring 6 of the convex portion 52c. It is provided around. Further, the lower mold 52 is formed with the bend forming protrusions 52a and 52b at positions where the bend portions 10a and 10b of the prepreg 20 are placed, and accordingly, the upper mold 51 is also provided with the bend forming protrusions 52a and 52b. Bending formation recesses 51a and 51b are formed at positions corresponding to 52b. The mold surface of the mold 50 is coated with a release agent. In addition, a primer having an adhesive action may be interposed between the prepreg 20 (frame 3) and the guide ring 6 in order to increase the fixing strength between the prepreg 20 and the guide ring 6.

Further, the laminated prepreg 20 set in the lower mold 52 as described above is schematically shown in FIG. 8A, but the opening 7a of the ring holding portion 7 is formed in advance, and May be set in the lower mold 52 in a state of being entirely overlapped with each other, or may be stacked in plural times such as set one by one. In this embodiment, since the mold 50 is divided into upper and lower parts as described above, the prepreg 20 is placed on the lower mold 52 and held in a predetermined shape according to the shape of the mold. Of course, the mold is merely an example, and the mold splitting direction can be any direction such as a left-right direction or an inclined direction. For example, in the case of a fishing line guide having two supporting legs 8, the upper die 51 may be divided into left and right.

Then, after setting the prepreg 20 and the guide ring 6 in the lower mold 52 in this way, the synthetic resin of the prepreg 20 flows and the prepreg 20 and the guide ring 6 are fixed to the guide ring 6 so that the reinforcing fibers are locked and fixed. By pressing the upper mold 51 against it, the prepreg 20 and the guide ring 6 are integrally pressure-molded. Specifically, in the case of the present embodiment, the pressure molding causes the prepreg 20 and the guide ring 6 to be compressed in the thickness direction T as shown in FIG. 8B, and the reinforcing fiber of the prepreg 20 is compressed. 20a and the synthetic resin 20b enter into the annular groove 6b on the outer periphery of the guide ring 6. As a result, the fishing line guide 1 is locked with the reinforcing fiber 20a locked and fixed to the guide ring 6 by the flow of the synthetic resin 20b due to the molding pressure when the frame (prepreg 20) 3 and the guide ring 6 are integrally molded. The fixed portion 19 is formed. Further, in such pressure molding, the density of the reinforcing fibers 20a increases due to the flow of the synthetic resin 20b, and the strength of the bent fishing line guide main body where stress concentrates easily is improved. In the present embodiment, in order to enhance the reinforcing effect of the prepreg 20 and contribute to the locking and fixing of the reinforcing fiber 20a with respect to the guide ring 6 due to the flow of the synthetic resin 20b, the reinforcing fiber 20a serves as the ring holding portion 7 of the frame 3. It is preferable that the long fibers have a length of 2.0 mm or more longer than the width dimension H (see also FIG. 2) of, for example, longer than the outer diameter of the guide ring 6.

After that, a heating step is performed to mold the synthetic resin 20b (matrix resin) (which causes the guide ring 6 and the frame 3 (prepreg 20) to be heat-sealed or heat-bonded), and then the molded product (the bent portion 10a). , 10b and the guide ring 6 as a plate-like body 30 (see FIG. 5) are taken out from the mold 50.

Next, the frame 3 is cut out from the plate-shaped body 30 so as to have a predetermined shape. As described above, since the prepreg 20 is the plate-shaped body 30 in which the bent portions 10a and 10b are formed after the heat treatment, cutting by press working, cutting by liquid (water jet, etc.), or cutting tool (end mill, etc.) It is possible to cut out a plurality of frames 3 from one plate-shaped body 30 shown in FIG. 5 by adopting an arbitrary method such as cutting out according to ), and efficiently manufacture a lightweight and high-strength fishing line guide. It becomes possible.

In addition, at the time of this processing, it is preferable to simultaneously form the basic outer shape of the frame 3, that is, the supporting leg portion 8 having the opening 8a, but these may be formed in separate steps. Further, the plate-shaped body 30 is not limited to one simple planar shape, and the laminated thickness may be changed depending on the position, or the plate-shaped portion may extend in a plurality of directions (T-shaped, inverted Y-shaped, etc.). And may include a curved surface shape, and further, a plurality of plate-shaped portions may be combined.

Next, detailed processing is performed as needed. This detailed processing corresponds to, for example, forming the shape of the fixed portion 5 into a curved surface so that it can be easily placed on a fishing rod, or polishing the end portion of the fixed portion so that it is easy to wind or fix the thread. ..

Next, the surface treatment of the frame 3 is performed. For example, barrel processing is performed to remove surface burrs and finish polishing to the extent that surface gloss is obtained. With respect to the degree of polishing, it is possible to arbitrarily adjust the polishing agent, polishing time, etc., depending on the size and shape of the fishing line guide, material characteristics, and the like. By performing such barrel processing, the frame 3 can be polished without cutting the reinforcing fibers, the strength can be stabilized, and a fishing line guide with an excellent appearance can be obtained.

When performing such a polishing step, it is preferable to perform polishing so that the reinforcing fibers are partially exposed and the matrix resin partially remains on the surface of the frame. By doing so, it becomes possible to further improve the gloss of the polished surface.

Next, a coating is formed on all or part of the frame 3 as needed. For example, it is possible to perform coating for the purpose of improving the appearance and protection of the frame body, or vapor-depositing metal or ceramics.

In the present embodiment, the prepreg set in the mold 50 during press molding is a plate-shaped prepreg sheet, but the set prepreg itself may have the shape of the frame 3 as it is. Such a frame-shaped prepreg can be realized by various molding methods including cutting and sewing.

Next, when forming the frame 3 with the prepreg 20 as described above, a preferable arrangement mode of the prepreg 20 will be described.

The frame 3 of the present embodiment is composed of a plurality of fiber reinforced resin layers in which prepregs in which reinforcing fibers are impregnated with synthetic resin are laminated. In the present embodiment, as an example, as shown in FIG. 4, an axial length direction fiber resin layer 21 in which reinforcing fibers are aligned along the axial length direction of the fishing rod and a predetermined angle with respect to the axial length direction of the fishing rod. And oblique fiber resin layers 22a and 22b in which reinforcing fibers are aligned in the crossing direction, and a woven fabric layer 23 in which reinforcing fibers are knitted.

Specifically, in the present embodiment, in the neutral axis area (the neutral axis is indicated by X in FIG. 4), which is an intermediate position of the thickness of the frame 3, the axis is formed by the prepreg in which the reinforcing fibers are aligned in the axial direction. A long direction fiber resin layer 21 is provided, and a predetermined angle (the tilt angle is arbitrary but preferably 15 to 75 degrees, more preferably 30 to 60 degrees) with respect to the axial direction on the outside (both sides) thereof. The oblique fiber resin layers 22a and 22b are arranged by the prepreg in which the reinforcing fibers are aligned with each other, and the reinforcing fibers are further provided in the outermost layer (the entire surface on both sides, but it may be a partially outermost area). The woven fabric layer 23 is arranged by the knitted prepreg. The axial length direction fiber resin layer 21 may have a plurality of layers (1 to 4 layers) (the laminated body is preferably formed of 3 to 20 layers as a whole). Further, regarding the oblique fiber resin layers 22a and 22b, the directions of the reinforcing fibers in the respective layers may be different.

The fishing line guide 1 in which the woven fabric layer 23 (the reinforcing fibers 20a″ knitted and knitted) is arranged as the outermost layer in this manner is also shown in FIG. 6(b). The outermost layer is a layer containing fibers 20a′ extending along the outer periphery of the frame 3 as shown in FIG. 6(a) so as to contribute to the promotion of the fastening and to improve the strength. In any case, the prepreg 20 includes at least fibers extending along the flow direction of the synthetic resin so as to promote locking and fixing of the reinforcing fibers to the guide ring 6.

Thus, when forming the fishing line guide 1 made of fiber reinforced resin, it is possible to select and stack prepregs such that the reinforcing fibers are oriented in at least three directions when the frame 3 itself is viewed in plan. preferable. That is, by setting the directional directions of the reinforcing fibers in three or more directions, it is possible to efficiently form a lightweight and strong fishing line guide.

It is effective to dispose the woven fabric layer 23 as the outermost layer of the frame 3 as in the arrangement of the prepreg described above. This is because the surface of the frame 3 is a portion that easily comes into contact with other objects and easily peels off, and during actual fishing, the tension of the fishing line causes the frame to bend, etc. Since it may be damaged or damaged, disposing the woven fabric layer in which the reinforcing fibers are knitted in this surface area can effectively prevent the reinforcing fibers from tearing or peeling and improve the strength. And, because it becomes possible to achieve stabilization.

The above is the description of the integral structure of the metal guide ring 6 having the annular groove 6b on the outer peripheral surface and the frame 3 by press molding. However, even when the guide ring 6 is formed of ceramic, the press The locking and fixing portion 19 described above can be formed by molding. One such example is shown in FIGS. 9 and 10.

FIG. 9 is a partially enlarged view corresponding to part A of FIG. 7, and FIG. 9A shows an arrangement state of the ceramic guide ring 6 and the prepreg sheet 20 before press molding according to FIG. 7. FIG. 9B is a schematic schematic sectional view showing the ceramic guide ring 6 and the prepreg sheet 20 which are integrated by the press molding according to FIG. 7. Further, (a) of FIG. 10 shows a diagram corresponding to the diagram of (a) of FIG. 9 on the upper side, and schematically shows the peripheral parts of the guide ring and the prepreg sheet in the state of (a) of FIG. 9 on the lower side. FIG. 10B is a schematic cross-sectional view (a partially enlarged view of a portion B on the upper side), and FIG. 10B shows a diagram corresponding to the diagram of FIG. 9B on the upper side and FIG. 9B on the lower side. FIG. 7 is a schematic schematic cross-sectional view (partially enlarged view of the upper part B) of the peripheral portion of the guide ring and the prepreg sheet in the state of (b). As can be seen from these figures, after the prepreg 20 and the guide ring 6 are set in the lower mold 52, the synthetic resin of the prepreg 20 flows and the reinforcing fibers are locked and fixed to the guide ring 6 so that the reinforcing fibers are locked and fixed. By pressing the upper mold 51 (see FIG. 7) against the ring 6, the prepreg 20 and the guide ring 6 are integrally pressure-molded. Specifically, as shown in (b) of FIG. 9 and (b) of FIG. 10, the prepreg 20 and the guide ring 6 are compressed in the thickness direction T by this pressure molding, and the prepreg 20 is reinforced. The fibers 20a run or bite together with the synthetic resin 20b onto the outer peripheral edge of the guide ring 6 (for example, so as to be flush with the outer surface of the guide ring 6). As a result, the fishing line guide 1 is locked with the reinforcing fiber 20a being locked and fixed to the guide ring 6 by the flow of the synthetic resin 20b due to the molding pressure when the frame (prepreg 20) 3 and the guide ring 6 are integrally molded. The fixed portion 19 is formed. In order to facilitate the locking and fixing of the reinforcing fiber 20a, it is preferable that the surface of the ceramic guide ring 6 is rough. By doing so, the reinforcing fibers are locked so as to enter the irregularities of the rough surface, and the formation of the locking fixing portion 19 is promoted.

FIG. 11 shows three modified examples of the locking and fixing portion 19. In all of these modified examples, the outer peripheral edge of the guide ring 6 is processed to promote the locking and fixing of the reinforcing fiber 20a to the guide ring 6. That is, in the first modification shown in FIG. 11A, the stepped portion 6c is formed on the outer peripheral edge of the guide ring 6 so that the reinforcing fiber 20a is locked and fixed to the stepped portion 6c. There is. Further, in the second modification shown in FIG. 11B, the tapered portion 6d is formed on the outer peripheral edge of the guide ring 6 so that the reinforcing fiber 20a is locked and fixed to the tapered portion 6d. There is. Further, in the third modified example shown in FIG. 11C, the reinforcing fiber 20a is locked and fixed to the R surface portion 6e by forming the arc-shaped R surface portion 6e on the outer peripheral edge of the guide ring 6. I am trying.

As described above, according to the present embodiment, the frame 3 and the guide ring 6 are not press-fitted or adhesively fixed by an adhesive, and the frame 3 and the guide ring 6 are combined by molding pressure during integral molding. Since the reinforcing fibers are integrally fixed and fixed to the guide ring 6 by the flow of resin, the reinforcing fibers are fixedly attached to the guide ring 6 without being affected by the dimensional error of the guide ring 6 and without using an adhesive agent. However, the guide ring 6 can be firmly and accurately fixed to the ring holding portion 7 of the frame 3.

That is, according to the present embodiment, since it is not necessary to press-fit the guide ring 6 into the ring holding portion 7, it is impossible to attach the guide ring 6 or the guide ring 6 falls off due to a dimensional error in manufacturing the guide ring 6. Inconvenience can be avoided. Further, according to the present embodiment, since the adhesive is not involved, the protrusion of the adhesive from the ring holding portion 7 and the accompanying wiping-off process of the adhesive can be avoided. Further, the solidification of the remaining adhesive does not hinder the insertion of the fishing line, and the adhesive fixing force of the guide ring 6 does not decrease due to poor adhesion. Further, since the guide ring 6 is centered during molding, it is possible to avoid the inconvenience that the center of the guide ring 6 deviates from the center of the opening 7a of the ring holding portion 7. As a result, since the press-fitting and the adhesive fixing work can be eliminated, the attachment of the guide ring 6 to the frame 3 can be automated.

Although the embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, the fishing line guide may have various forms such as one having two support legs and a stepless 3D structure, and therefore, a corresponding prepreg can be used. Further, depending on the mounting position of the fishing rod, the bent portion may not be formed in the frame, and the prepreg forming the frame may have a single-layer structure of a woven fabric layer. Of course, the laminated structure as described above may be used, and the bent portion may be formed separately. In addition, as described above, the prepreg that constitutes the frame has a structure in which the reinforcing fibers are efficiently lightened while reducing weight if the reinforcing fibers have three or more directional directions in a plan view in the stacked state. Although it is possible to improve, the direction of the reinforcing fibers of the prepreg forming each layer and the stacking position thereof are not particularly limited and can be appropriately modified. In this case, as described above, the outermost layer of the frame is preferably provided with a woven fabric layer so that damage or the like can be effectively prevented.
