JP 2006-340661 A

  In the above-described known technology, the frame is made of a metal material, so the weight is heavy, the performance such as specific strength, specific rigidity, flexibility, etc. is poor. It is a bottleneck in improving For example, in a fishing rod that is required to be lighter, if a large number of fishing line guides as described above are attached along the axial length direction, desired performance cannot be exhibited.

  The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a fishing line guide that is light in weight and excellent in specific strength, specific rigidity, and flexibility.

  In order to achieve the above-described object, the present invention includes a frame including a ring holding portion and a support leg portion made of a fiber reinforced resin made of a laminated material in which a plurality of fiber reinforced prepregs are stacked in the front-rear direction, and the ring A fishing line guide to which a guide ring through which a fishing line is inserted is attached to a holding part, wherein a plurality of layers of the fiber reinforced resin appearing on a side surface of the frame are formed flush with each other, and a surface shape of the side surface is made convex. It is characterized by that.

  Since the fishing line guide having the above-described structure is composed of a laminated material having a plurality of fiber reinforced resin layers in which fiber reinforced prepregs are laminated, the weight can be reduced and the specific strength, specific rigidity, and flexibility are excellent. It becomes the composition. In this case, a plurality of layers of fiber reinforced resin appearing on the side surface of the frame are formed flush with each other, and the surface shape of the side surface is convex, so that even if the fishing line comes into contact, the fishing line or the laminated material is damaged. It is possible to maintain the above-described performance over a long period of time because it is possible to suppress the adhesion of the laminated material and to prevent the laminated material from being peeled off.

  According to the present invention, a fishing line guide that is light in weight and excellent in specific strength, specific rigidity, and flexibility can be obtained.

  Hereinafter, an embodiment of a fishing line guide according to the present invention will be described with reference to the drawings.

  First, a configuration example of a fishing line guide according to the present invention will be described with reference to FIGS. In these drawings, FIG. 1 is a longitudinal sectional view of a fishing line guide, FIG. 2 is a view of FIG. 1 viewed from the direction of arrow A, and FIG. It is a figure which shows a state. In FIG. 1, the direction of arrow A coincides with the axial direction of the fishing rod when the fishing line guide is attached to the fishing rod, and FIG. 3 is a view of the tip rod side from the main rod side. Yes. Further, the fishing line guide is attached so that the ring holding part is on the tip side and the fixing part is on the side of the head. In the following, the front side means the tip side, and the rear side means the base end side.

  The fishing line guide 1 includes a frame 3 formed of a laminated material having a plurality of fiber reinforced resin layers in which fiber reinforced prepregs (hereinafter referred to as prepregs) in which reinforced fibers are impregnated with synthetic resin are laminated (configuration of prepregs). The detailed description of the method for manufacturing the frame and the frame will be given later).

  The laminated material is made of a fiber reinforced resin material formed into a plate shape having an appropriate thickness by stacking a plurality of sheet-like prepregs, cured by heating, pressing, and for each prepreg stacked in the thickness direction. A plurality of formed layers are formed.

  The frame 3 includes a fixing portion 5 attached to the outer surface of a fishing rod (rod tube) 40, a ring holding portion 7 to which a guide ring 6 into which a fishing line is inserted is attached, and the ring holding portion 7 and the fixing portion 5. And a support leg portion 8 that connects the two, and is formed in a plate shape in which the width in the left-right direction is larger than the thickness of the ring holding portion 7 in the axial direction (arrow A direction in FIG. 1; front-rear direction). .

  The fixing portion 5 is a portion (also referred to as a foot portion) that is fixed to the surface of the fishing rod at the lower end of the frame. In the present embodiment, the fixing portion 5 extends in the axial direction, and the contact surface 5a on the back side of the fishing rod is In a state where it is placed on the surface, it is fixed by thread fastening, adhesion or the like. In addition, the fixing | fixed part 5 can take various shapes, such as one leg and two legs.

  The ring holding part 7 is a part for fastening the guide ring 6 so as to guide the fishing line in a state of being separated from the surface of the fishing rod. The ring holding part 7 is formed with an opening 7a for fitting and fixing the guide ring 6 and has a substantially circular outer shape as a whole. The guide ring 6 inserted into the opening 7a is formed in a ring shape and is made of a member having a small sliding resistance at the fishing line guide surface 6a, which is the inner peripheral surface thereof, such as titanium, aluminum, SUS, ceramics, or the like. Is formed. The guide ring 6 is fitted and fixed to the opening 7 a of the ring holding portion 7 after the frame 3 is integrally formed by the prepreg.

  The support leg 8 is a part for connecting the fixing part 5 and the ring holding part 7 so that the guide ring 6 is separated from the surface of the fishing rod.

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

  When forming the bent portion as described above in the frame 3, in particular, by forming the second bent portion 10 b in the support leg portion 8, the bending angle by bending the entire frame can be set stepwise. Thus, the strength can be improved by dispersing the stress concentration. Further, if a plurality of bent portions 10a and 10b are formed in the frame 3 as described above, a bent portion (in the drawing, in the boundary portion between the fixed portion 5 and the support leg portion 8 or in the vicinity thereof) It is preferable to set the bending angle of the bent portion (corresponding to the second bent portion 10b in the drawing) formed on the support leg portion 8 smaller than that of the first bent portion 10a. Specifically, the bending angle θ1 of the bending portion formed at or near the boundary portion between the fixed portion 5 and the supporting leg portion 8 is in the range of 30 to 90 degrees, and the bending portion formed on the supporting leg portion 8 is. The bending angle θ2 of the part is preferably in the range of 0 to 45 degrees with an angle smaller than that (θ1> θ2), and preferably 30 degrees or more and 100 degrees or less when both angles are combined.

  As shown in FIG. 1, the bending angle is defined by an angle at which tangent lines intersect before and after the bent portion. As described above, when the two bent portions 10a and 10b are formed on the frame, the relationship between the angles is preferably set as described above. Further, the bending angle between the fixing portion 5 and the ring holding portion 7 (the angle at which the lower surface tangent of the fixing portion 5 and the ring holding portion 7 intersect) θ3 may be set in the range of 30 to 100 degrees. preferable. Further, the above-described support leg portion 8 is formed in a straight line between the two bent portions 10a and 10b, but may be formed in a curved shape having a predetermined curved surface between the two bent portions 10a and 10b. Alternatively, the entire support leg portion may be formed of a curved surface.

  By forming the bent portion so as to have such an angular relationship, stress concentration on the specific bent portion can be prevented, and the strength can be stabilized.

  In addition, the bent portions 10a and 10b formed in the frame as described above are regions that are easily damaged due to stress concentration. However, by using a manufacturing method and a prepreg configuration as described later, Strength and specific rigidity are improved.

  As will be described later, the frame 3 is formed by pressing or the like from a prepreg in which a bent portion having a configuration as described above is formed in advance (which is a plate-like body after thermoforming). At this time, it is formed to have a predetermined outer shape. In the present embodiment, as shown in FIG. 2, the frame 3 has a support leg portion 8 that rises from the end of the fixed portion 5 via the first bent portion 10a, and gradually becomes wider as it moves upward. The ring 6 is integrally connected to a substantially circular ring holding portion 7 in which an opening 7a is formed. In this case, as shown in the figure, the support leg portion 8 may be formed with an opening (thickening) 8a in order to reduce the weight.

  Next, a method for forming the frame 3 having the above-described form and a specific laminated structure of the prepreg will be described with reference to FIGS. First, an overall manufacturing process will be described with reference to FIGS. 4 and 5, and then, referring to FIGS. 6 and 7, a plurality of prepregs constituting the frame are stacked and stacked. The arrangement state of the reinforcing fibers of the prepreg will be described.

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

  First, the prepreg as described above is cut into a predetermined shape, and this is overlaid so as to form a plurality of layers. The number of prepregs to be stacked (number of layers) and the configuration of individual prepregs are not particularly limited. However, as described above, the bent portions 10a and 10b are formed in the frame 3, and the frame 3 can be used in use. In consideration of the load, the characteristics of the fishing rod to be mounted, the mounting portion, and the like, the type of prepreg and the conditions for stacking are arbitrarily adjusted.

  The prepregs laminated in this way are set in a mold 50 as shown in FIG. The mold 50 according to the present embodiment includes an upper mold 51 and a lower mold 52 that are divided vertically, and the laminated prepreg (laminated material 20) is set at a predetermined position of the lower mold 52. Between the upper mold | type 51 and the lower mold | type 52, the cavity part 50a is formed according to the position where the laminated material 20 is set, and the mold release agent is coated in the surface area.

  The upper mold 51 constituting the mold 50 is concave and the lower mold 52 is convex, and the cavity portion (this cavity is formed between the two so that the frame 3 is formed when both are pressed. 50a is formed (corresponding to the thickness of the frame 3). Then, when the laminated material 20 is placed on the lower mold 52, the bent forming convex parts 52a and 52b are formed at positions corresponding to the bent parts 10a and 10b, and the upper mold 51 is bent. Bending formation concave portions 51a and 51b are formed corresponding to the convex portions 52a and 52b.

  Note that the laminated material 20 may be set in a lower mold in a state where the whole is overlapped at a time, or may be laminated in a plurality of times, for example, one by one. By dividing into a plurality of times as described above, the movement of the reinforcing fibers can be reduced, and the lower mold 52 can be accurately set at a predetermined position. In the present embodiment, as described above, since the mold 50 is divided vertically, the laminated material 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 dividing direction can be in any form such as a horizontal direction or an inclined direction.

  And after setting the laminated material 20 to the lower mold | type 52, the laminated material 20 is pressurized and fixed. About this pressurization and fixation, you may clamp | tighten with the upper mold | type 51, and may press with a hand or a pressing tool. At this stage, the shape corresponding to the shape of the frame after molding, including the bent portion, is maintained, thereby preventing the occurrence of internal residual stress after molding, and the strength can be improved and stabilized. (At this stage, each prepreg is in an uncured state (including after temporary curing), and the bent portion is formed before heat curing).

  Thereafter, a heating step is performed, the matrix resin is cured and molded, and then a molded product (a plate-like body 30 having a bent portion) is taken out from the mold 50.

  In addition, when the above-described bent portion is pressed and cured by the mold 50, it is preferable that the bent portion is pressed relatively stronger than the front and rear regions. Thus, by strongly pressing the area of the bent portion, voids in the bent portions (10a, 10b) of the molded frame can be prevented, and the strength can be improved and stabilized. In addition, the bent portions 10a and 10b of the molded frame 3 can have a higher fiber ratio than the front and rear regions (fixed portions and supporting leg portions), so that the bent portions that are easily damaged are reinforced. It becomes possible to do.

  Next, the frame is cut out from the plate-like body 30 so as to have a predetermined shape. As described above, since the prepreg is a plate-like body in which a bent portion is formed after the heat-curing treatment, it is cut out by pressing, cut out with a liquid (water jet, etc.), cut out with a cutting tool (end mill, etc.), etc. By adopting an arbitrary method, as shown in FIG. 5, it becomes possible to cut out a plurality of frames 3 from one plate-like body 30, and it is possible to efficiently manufacture a lightweight and high-strength fishing line guide. It becomes possible.

  During this processing, it is preferable to simultaneously form the basic outer shape of the frame 3, that is, the ring holding portion 7 having the opening 7a, the support leg portion 8 having the opening 8a, etc., but these are formed in separate steps. It may be formed. In addition, the plate-like body 30 is not limited to a simple planar shape, but the laminated thickness is changed depending on the position, or the plate-like portion extends in a plurality of directions (T-shape, inverted Y-shape, etc.) Or a curved surface shape, or a plurality of plate-like portions may be combined.

  Next, detailed processing is performed as necessary. This detailed processing corresponds to, for example, forming the shape of the fixing portion 5 into a curved surface so that it can be easily placed on a fishing rod, or polishing the end of the fixing portion so as to facilitate winding and threading. .

  Next, a surface treatment of the frame is performed. As will be described later, this surface treatment is performed so that a plurality of fiber reinforced resin layers (laminated material 20) appearing on the side surface of the frame are flush with each other, and the surface shape of the side surface is convex. Is done.

  In addition, when performing such a polishing process, it is preferable to polish so that a part of the reinforcing fibers are exposed on the surface of the frame and a part of the matrix resin remains. By doing so, it becomes possible to further improve the gloss of the polished surface.

  Next, a film is formed on the whole or a part of the frame as necessary. For example, it is possible to perform coating to improve the appearance and protect the frame body, or to deposit metal or ceramics.

  Then, the guide ring 6 is attached to the portion of the opening 7a of the frame formed as described above. As a method for attaching the guide ring, press-fitting, adhesion, curling, or any other fixing method can be employed.

  According to the fishing line guide formed by the manufacturing method as described above, the weight is lighter than that made of metal, and further, the structure is excellent in specific strength, specific rigidity, and flexibility. It becomes possible. For this reason, even if a large number of such fishing line guides are mounted, the entire fishing rod is not increased in weight, and the performance of the fishing rod is improved. In particular, a portion such as a tip rod can be further reduced in weight, so that it is easy to sense delicate hits, and the performance of the fishing rod can be further improved.

  Next, when the frame 3 is formed by the prepreg as described above, a preferred arrangement mode of the prepreg and a surface treatment method will be specifically described with reference to FIGS. In these drawings, FIG. 6 is an enlarged view showing a laminated structure of prepregs constituting the frame, and FIG. 7 is a cross-sectional view taken along the line AA of FIG.

  The fishing line guide shown in FIG. 6 is attached to the fishing rod 40 in such an orientation that the ring holding portion 7 is on the front side (the tip side) and the fixing portion 5 is on the rear side (the main rod side). FIG. 6 is a view of the frame 3 as viewed from the front side (the tip side).

  As described above, the frame 3 is constituted by the laminated material 20 having a plurality of fiber reinforced resin layers in which prepregs in which reinforcing fibers are impregnated with synthetic resin are laminated in the front-rear direction. Layer prepregs are used. Here, for the sake of convenience, the first layer 20a, the second layer 20b, the third layer 20c, and the fourth layer 20 are sequentially moved from the front side (the tip side) to the rear side (the former side). It is defined as a layer 20d, a fifth layer 20e, a sixth layer 20f, a seventh layer 20g, and an eighth layer 20h (in such a laminated structure, a gap between the fourth layer 20d and the fifth layer 20e, which is the center on the laminated side, is defined as It becomes the center C of the laminated material 20). In FIG. 6, the direction X in which the frame 3 (support leg 8) extends is defined as the longitudinal axis X of the frame, and the fiber direction in each layer is indicated by diagonal lines or lattice lines.

  The front and rear surfaces (the first layer 20a and the eighth layer 20h) that are the outermost layers of the laminated material 20 are constituted by fiber reinforced resin layers of woven fabric. In this case, it is desirable that the reinforcing fibers constituting the woven fabric are set so as to be in a direction along the longitudinal axis X and in a direction perpendicular thereto.

  The inner layer sides (second layer 20b and seventh layer 20g) of the first layer 20a and the eighth layer 20h are aligned in one direction along the longitudinal axis X (which may not exactly match). It is comprised by the axial direction fiber reinforced resin layer which consists of a reinforced fiber.

  Further, the inner layer side (the third layer 20c and the sixth layer 20f) is an oblique fiber reinforced resin in which the reinforcing fibers are obliquely inclined rightward (defined by +) with respect to the longitudinal axis X when viewed from the front. Consists of layers. In this case, it is only necessary to incline in the right direction with respect to the longitudinal axis X, but the inclination angle with respect to the longitudinal axis X is preferably in the range of 10 ° to 60 °, and the oblique angles of the reinforcing fibers of both layers are It does not have to match exactly.

  Further, the inner layer side (the fourth layer 20d and the fifth layer 20e) is an oblique fiber reinforced resin in which the reinforcing fibers are inclined leftward (defined by −) with respect to the longitudinal axis X when viewed from the front. Consists of layers. In this case, it is only necessary to incline leftward with respect to the longitudinal axis X, but the inclination angle with respect to the longitudinal axis X is preferably in the range of −10 ° to −60 °, and the oblique angles of the reinforcing fibers of both layers Does not have to match exactly.

  Therefore, the layers before and after the center C in the laminated material 20 are both oblique fiber reinforced resin layers (the fourth layer 20d and the fifth layer 20e) in which the reinforcing fibers are inclined in the left direction, Both are oblique fiber reinforced resin layers (third layer 20c and sixth layer 20f) in which the reinforcing fibers are inclined to the right. That is, the oblique fiber reinforced resin layer in which the reinforcing fibers are inclined in the opposite directions with respect to the longitudinal axis X of the frame is disposed on one side and the other side with respect to the center C of the laminated material 20. (The fourth layer 20d and the sixth layer 20f, and the third layer 20c and the fifth layer 20e).

  Further, in the aspect of the present embodiment, oblique fiber reinforced resin layers in which reinforcing fibers are inclined in the same direction with respect to the longitudinal axis X of the frame are arranged on one side and the other side with respect to the center C of the laminate 20. The fourth layer 20d and the fifth layer 20e, and the third layer 20c and the sixth layer 20f are provided.

  The frame (see FIG. 5) cut out and molded from the above-described laminated material 20 has a cut surface on which the laminated state can be seen as a side surface. For this reason, it is possible to make the fishing line guide more durable in addition to the above-described effects by performing the treatment so that water does not enter or peel off from the boundary portion of the laminated layer visible on the side surface.

  Furthermore, since there is a possibility that the fishing line may come into contact with the side surface of the frame, it is preferable that the fishing line is prevented from being damaged and that the surface itself is not damaged. In this case, since the cross section of the reinforcing fiber is formed in a substantially circular shape, when the cutting is performed as shown in FIG. 5, the exposed portion (exposed end surface of the fiber) of the side surface is the reinforcing fiber with respect to the longitudinal axis X. In many cases, the fiber end faces are elliptical and are arranged on the side surfaces in many cases, and the exposed end faces of such fibers appear and are scratched. The surface condition is difficult.

  In such an exposed state (side surface state), a plurality of laminated layers are flush with each other, and a polishing process is performed so that the surface shape on the side surface is a convex surface. I try to prevent scratches more effectively. In this case, the interlayer in the prepreg exposed on the side surface may be slightly recessed by performing a polishing process, but the matrix resin (synthetic resin) fills it so as to close it, There is no cause.

  The above-described polishing treatment can be realized, for example, by removing burrs on the surface by performing barrel polishing and by performing final polishing to such an extent that the gloss of the surface can be obtained. Specifically, as shown in FIG. 7, the surface shapes of the surfaces 25 and 25 of both sides S <b> 1 and S <b> 2 of the laminated material 20 (frame) protrude outward when the cross section of the frame is regarded as a rectangular shape R. It has a convex shape, and this convex surface is formed continuously in the longitudinal direction along the side surface of the frame.

  Further, when the above-described polishing treatment is performed, the reinforcing fibers and the matrix resin are finished in a smooth shape so that they are flush with each other (the end portions of the reinforcing fibers may slightly protrude, but are substantially flush with each other). Formed). Specifically, the surfaces 25 and 25 on the side surfaces are polished so that the average surface roughness (Ra value) is 10 μm or less.

  As a result, the prepreg is prevented from being peeled off between layers, resulting in a highly durable frame structure, and even if the fishing line comes into contact, it is prevented from being caught or damaged. In addition, by polishing the surfaces 25 and 25 until the average surface roughness (Ra value) is 1 μm or less, the surface through which the reinforcing fibers are viewed is surely finished in a smooth surface, and there is no damage that leads to breakage. More preferable.

  In the cross-sectional shape shown in FIG. 7, there is less damage to the fishing line that is finished in contact with the curved surface from the front surface 26 a on the first layer 20 a side to the rear surface 26 b on the eighth layer 20 h side. In such a convex surface shape, it is preferable to polish so that the curvature of the area | region (corner | corner part) L2 of the front side and the back side becomes smaller than the area | region L1 of the center side.

  As a result, it is possible to prevent the central region L1 from being easily hit by another object and from being easily in contact with the fishing line.

  In addition to the state shown in FIG. 7, for example, as shown in FIG. 8, the surface polishing method may include a corner portion 25 </ b> A that transitions from the front surface 26 a and the rear surface 26 b to the side surface as shown in FIG. 8. Chamfering, making the entire side surface portion 25B flat (some may be flat), or bending the region that transitions from the flat side surface portion 25B to the front surface 26a and the rear surface 26b without chamfering You may finish in the shape.

  The convex shape of the side surface is formed so that the center side protrudes outwardly from the region transitioning from the front surface 26a and the rear surface 26b formed at both front and rear ends of the side surface, and has a mountain shape in the front-rear direction. This convex shape is formed along the longitudinal direction of the side surface. Although the most projecting position is the front and rear intermediate part, this is not limited to the intermediate part.

  Moreover, about the prepreg which comprises the above laminated materials 20, it is possible to make it lightweight and to enlarge rigidity by making resin impregnation amount into 15 to 60 weight%. Furthermore, within such a range, it is possible to make a frame having a supple and stable strength, particularly by setting it to 20 to 40% by weight.

  In the above-described configuration, the layers having the woven fabric-like reinforcing fibers (first layer 20a, eighth layer 20h) are disposed on the front and rear surface sides, so that the direction orthogonal to the longitudinal axis X is provided. However, since the corner portion is polished as described above, such a layer does not reach the side surface in practice.

  Accordingly, in the configuration of the laminated material 20 described above, the reinforcing fibers reaching the side surface are arranged in parallel to the side surface or reach the side surface in an inclined direction, and the inclination angle is shallow and appears on the side surface. Since most of the reinforcing fibers of the fiber reinforced resin reach the side surface at an angle of 45 ° or less (at least 60 ° or less), the surface can be easily polished.

  According to the configuration of the laminated material 20 as described above, the weight of the frame itself can be reduced, and a fishing line guide excellent in specific strength, specific rigidity, and flexibility can be constructed. In particular, a plurality of layers of fiber reinforced resin appearing on the side surface of the frame 8 are formed flush with each other, and the side surface shape is convex, so that even if the fishing line comes into contact, the fishing line or the laminated material is damaged. In addition, the above-described performance can be maintained over a long period of time because the laminate material is prevented from being peeled off.

  Further, in the configuration described above, the reinforcing fibers are in the same direction with respect to the longitudinal axis X of the frame in the direction away from the center C in the stacking order on one side and the other side of the center C of the laminated material 20 respectively. Since the slanted fiber reinforced resin layers are inclined in the same order, the bending rigidity and the torsional rigidity can be made the same before and after the frame of the fishing line guide 1, and the frame is constant against the load. This will prevent distortion in the direction.

  Moreover, the laminated material 20 having the above-described configuration includes axial fiber reinforced resin layers (second layer 20b and seventh layer 20g) made of reinforcing fibers aligned in one direction along the longitudinal axis X. As a result, the bending rigidity in the longitudinal axis direction can be increased.

  Furthermore, since the laminated material 20 having the above-described configuration includes the fiber reinforced resin layer of the woven fabric on the front and rear surfaces (the first layer 20a and the eighth layer 20h) which are the outermost layers, the reinforced fiber even when the fishing line contacts It is difficult to cause tearing or peeling, and the strength can be improved and stabilized, and the inner fiber-reinforced resin layer can be effectively protected.

  For the fiber reinforced resin layers 20a and 20h of such a woven fabric, as shown in FIG. 9, the mesh width w of the main fibers knitted with the reinforcing fibers (usually many reinforcing fibers were bundled. The fiber bundle is configured in a state, and since the fiber bundle is knitted to form a woven fabric, the mesh is specified by the width of the fiber bundle), and the width W of the support leg portion 8 of the frame 3 (here It is preferable to use a width that is smaller than the minimum width corresponding to the width of the part.

  By disposing such fiber reinforced resin layers 20a and 20h of woven fabric, it is possible to prevent the reinforcing fibers from being peeled and damaged more reliably, and to improve and stabilize the strength. Further, the above-described bent portions 10a and 10b can be relatively strengthened, and a fishing line guide that is lightweight and has an excellent strength balance can be obtained. Of course, it is preferable that the mesh widths of the fiber reinforced resin layers 20a and 20h of the woven fabric be smaller than the minimum widths in the fixed portions 5 and the ring holding portions 7 as well. .

  Moreover, in the arrangement | positioning aspect shown in FIG. 9, although the direction of the stitch of a woven fabric is along the up-and-down vertical direction AX, it is preferable to make this incline by the predetermined angle with respect to the vertical direction AX. By inclining in this way, the reinforcing fiber becomes a direction along the longitudinal axis X described above and a direction orthogonal thereto, and the reinforcing fiber can be effectively prevented from being broken or peeled off.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to an above-described structure, It can change variously.

  In the present invention, the frame portion constituting the fishing line guide is made of a fiber reinforced prepreg, and the specific strength, specific rigidity, etc. are increased, and the side surface of the frame is formed flush and finished in a convex shape. There is a feature.

  The shape of the side surface as described above may be formed by, for example, chemical polishing other than barrel polishing. As for the degree of polishing, it is possible to arbitrarily adjust the polishing agent, polishing time, etc. depending on the size, shape, material characteristics, etc. of the fishing line guide. By performing such processing, it is possible to polish the frame without cutting the reinforcing fiber, to stabilize the strength, and to make a fishing line guide with an excellent appearance.

  Further, regarding the prepreg constituting the above-described frame, the type of reinforcing fiber, the elastic modulus, the directing direction, the resin impregnation amount, the thickness and the like, and the lamination state are limited to the above-described embodiment. However, various modifications are possible.

  Furthermore, although the fishing line guide has been described as being fixed to the fishing rod by means of a thread stop or the like, for example, it may be configured as a floating guide that is slidably fitted to the fishing rod. If it is such an idle guide, the structure which does not form a bending part in the above-mentioned flame | frame 3 may be sufficient. That is, as shown in FIG. 10, the frame 3A is formed in a flat plate shape, and an opening 5d is formed on one end side as the fixing portion 5A (the opening 5d is provided on the fixing portion 5A), and the other end. On the side, an opening 7c that can fix the guide ring is formed as the ring holding portion 7A. Further, the support leg portion 8A that connects the fixing portion 5A and the ring holding portion 7A is formed with a lightening 8c as necessary. The sliding fixing ring 5c is attached to the opening 5d, and the unevenness formed on the inner surface of the cylindrical body by fixing a cylindrical body (not shown) to the opening 5d to which the sliding fixing ring 5c is attached. The strip portion and the fishing rod are engaged.

  As described above, the frame may have a configuration in which a bent portion is not formed according to the mounting position of the fishing rod, and the prepreg used in the frame constituting such a fishing line guide has a single layer structure of a woven fabric layer. Anyway. Of course, a laminated structure as described above may be used, and a bent portion may be formed separately. Alternatively, the portion (region indicated by reference numeral 5D) to which the sliding fixing ring 5c is attached is formed to be thicker than the ring holding portion 7A, but the overall thickness may be the same. It is possible to set arbitrarily.
