Description

  The present invention relates to a fishing line guide used for a fishing rod.

  In general, the fishing line guide is attached to the outside of the fishing rod at an interval in order to prevent the fishing line from adhering to the surface of the fishing rod. In such a fishing line guide, the guide ring is held by a metal frame, and the mounting foot is extended in the front-rear direction from the holding portion holding the guide ring in the longitudinal direction of the fishing rod. Some are fixed to a fishing rod (see, for example, Patent Document 1).

  In addition, an intermediate ring arranged between the outer ring and the inner ring made of a hard wear-resistant material and a mounting piece extending back and forth from the intermediate ring are continuously integrated with a thermoplastic synthetic resin mixed with reinforcing fibers. Some of them are formed (see, for example, Patent Document 2).

  As in the past, the fishing line guide with an integral structure in which a frame is formed by pressing a single plate material made of metal such as stainless steel or titanium alloy is heavy overall, and deforms the rod tube when attached to a fishing rod. It can be hurt. Furthermore, since it fixes to a fishing rod via the attachment leg extended in the front-back direction from a holding | maintenance part, the flexibility of the site | part which fixed the fishing line guide is inhibited. On the other hand, since the fishing line guide in which the intermediate ring and the attachment piece are integrally formed with the thermoplastic synthetic resin mixed with the reinforcing fiber is flexible, these disadvantages in the metal frame can be improved.

  However, the inner ring that acts as a guide ring for guiding the fishing line is formed of a hard wear-resistant material together with the outer ring, and it is difficult to securely hold it with an intermediate ring made of a synthetic resin material with a high degree of flexibility. is there.

  The present invention has been made based on such circumstances, and provides a fishing line guide that can alleviate the load acting on the frame that holds the guide ring and can reliably prevent the guide ring from falling off. Objective.

  In order to achieve the above object, according to the present invention, there is provided a fishing line guide having a guide ring for guiding a fishing line and a frame made of fiber reinforced resin provided with a holding hole for fitting the guide ring in a holding part, A protrusion that contacts the outer peripheral surface of the guide ring and a concave portion that does not contact the outer peripheral surface of the guide ring are formed on the inner peripheral surface of the holding hole along the fitting direction of the guide ring with respect to the holding hole. A fishing line guide is provided in which a fixing member that is disposed and formed of a material more flexible than the frame is disposed in a gap formed between the outer peripheral surface of the guide ring and the inner peripheral surface of the holding hole.

  The protrusion is preferably formed at an intermediate portion along the axial direction of the holding hole between the front surface and the rear surface of the holding portion.

  Further, the protrusion may be formed at a position deviated from the center position along the axial direction between the front surface and the rear surface toward the front surface side or the rear surface side.

  Further, a plurality of support portions may be provided radially inward along the circumferential direction on the inner peripheral surface of the holding hole, and the protrusion and the recess may be formed on the support portion. .

  The fixing member may cover an inner peripheral side surface portion of the holding portion adjacent to the holding hole.

  The protrusions are preferably arranged at the same axial position along the circumferential direction of the inner peripheral surface of the holding hole.

  According to the fishing line guide of the present invention, since the frame is formed of fiber reinforced resin, the fishing line guide is reduced in weight, the external force acting on the frame is reduced by bending, and the bending deformation of the frame is absorbed by the fixing member. The guide ring can be securely held and prevented from falling off.

  When the protrusion is formed between the front surface and the rear surface of the holding portion at the intermediate portion along the axial direction of the holding hole, even if a load acts, prevent damage from the protrusion. Can do.

  In particular, when the protrusion is formed at a position deviated from the center position along the axial direction to the front side or the rear side, the guide ring can be easily mounted and held by a flexible fixing member even if the frame is bent. This makes it difficult for the guide ring to fall off.

  In the case where a plurality of support portions project radially inward along the circumferential direction on the inner peripheral surface of the holding hole, and the protrusion and the recess are formed on the support portion, Even when the bending deformation along the radial direction occurs, the guide ring can be reliably held.

  When the fixing member covers the inner peripheral side surface portion of the holding portion adjacent to the holding hole, the fishing line can be reliably prevented from entering between the guide ring and the holding portion.

  When the protrusion is disposed at the same position in the axial direction along the circumferential direction of the inner peripheral surface of the holding hole, the outer peripheral surface of the guide ring can be held at the same position along the axial direction. The guide ring can be securely held.

Explanatory drawing when attaching a guide ring to the frame of a fishing line guide. Explanatory drawing of the state which attached the guide ring to the frame of the fishing line guide. An explanatory view of a part of a fishing line guide according to another embodiment. . Sectional drawing which follows the VII-VII line of FIG.

1 and 2 show a fishing line guide 10 according to an embodiment of the present invention. The fishing line guide 10 of this embodiment is formed as an outer guide that prevents the fishing line from adhering to the outer surface of a fishing rod 8 of a fishing rod. It can be attached to a required position on the outer periphery of the soot tube 8 formed with a slight gradient, and can be fixed using appropriate fixing means such as a spool, a thread stopper, or an adhesive. If necessary, it is held at a required position by appropriate friction holding means, and if necessary, along the axial direction parallel to the axis C of the tubule 8 from the front tip side to the rear base side. Then, it may be moved back and forth and held at a required position with frictional force.

  In the same manner as usual, the soot tube 8 is a deflection direction in which a fiber reinforced prepreg sheet obtained by impregnating a reinforcing fiber such as carbon fiber with a synthetic resin such as an epoxy resin is inclined at an appropriate angle with respect to the circumferential direction, the axial length direction, or the axial length direction. It is possible to use a hollow soot tube in which the plurality of fiber layers are laminated by winding them together.

  The fishing line guide 10 attached to the rod 8 includes a guide ring 12 and a frame 14 that holds the guide ring. The frame 14 is formed in a plate-like structure having a holding portion 18 through which a holding hole 16 into which the guide ring 12 is fitted and a support leg portion 20 that supports the holding portion 18 on one end side. The frame 14 is integrally formed with a fixing portion 22 on the other end side of the support leg portion 20, and the fixing portion 22 is fixed on the outer surface of the tub tube 8 by fixing means such as a bobbin or an adhesive. When the fishing line guide 10 is moved on the rod 8, the fixing portion 22 may be formed in a ring shape.

  As shown in FIG. 4, the guide ring 12 fitted and held in the holding hole 16 of the holding portion 18 has an inner surface formed by a smooth curved surface as a fishing line guide surface 12a. Guide the fishing line through the enclosed fishing line conduction hole. The guide ring 12 of the present embodiment is formed by a curved surface obtained by rounding both ends in the axial direction of the fishing line guide surface 12a in an annular shape, and its intermediate portion is formed in a cylindrical shape. The outer peripheral surface 12b is also formed by a curved surface with both ends in the axial direction rounded in an annular shape, and the intermediate portion is formed in a cylindrical shape having substantially the same outer diameter along the axial direction. The annular curved surface formed at both ends of the outer peripheral surface 12b is formed with a curved surface having a larger radius on the inner peripheral side than the outer peripheral side when viewed in the cross section of FIG. 4, but does not damage the fishing line. If so, these curved surfaces may have the same radius, and conversely, the outer peripheral side may be formed larger than the inner peripheral side.

  As shown in FIGS. 1 and 2, the guide ring 12 is held by the frame 14 with the center axis O of the fishing line passage hole oriented substantially parallel to the axis C of the rod 8. The guide ring 12 is preferably formed of a hard material having higher wear resistance than the frame 14, such as silicon carbide (SiC), alumina oxide, tungsten carbide, ceramic or metal. In any case, as will be described later, the guide ring 12 has an axial dimension longer than the wall thickness T of the holding portion 18 of the plate-shaped frame 14 to prevent the fishing line from directly contacting the frame 14. It is preferable to do.

  The holding portion 18 for holding the guide ring 12 has an outer peripheral edge portion 18a formed in a ring shape having a larger diameter than the guide ring 12, and the holding hole 16 formed as a through hole is a guide ring fitted therein. It is preferable to form it coaxially with the central axis O of the twelve fishing line passage holes.

  The support leg portion 20 has outer edge portions 20a extending in a smooth curved shape on both sides of the central axis O from a portion closer to the fixed portion 22 than the maximum diameter portion of the outer peripheral edge portion 18a of the holding portion 18, and these outer edge portions. Smoothly transitions to both edges of the fixed portion 22. Thereby, sufficient strength for holding the holding portion 18 at a required position is ensured, and further, formation of a corner portion where the fishing line is easily caught is prevented.

  If the width between the outer edge portions 20a of the support leg 20 is larger than necessary to maintain the required strength, a recess 20b as shown in FIG. Also good. Such a recess 20b is not limited to one, and a plurality of recesses 20b may be provided, or may be provided in one or both along the axial direction of the central axis O of the fishing line passage hole without forming a through hole. Good. In any case, it is preferable to form a smooth outer surface having no corners or protrusions that are easily hooked by fishing lines.

  The support leg portion 20 is integrally formed with a fixing portion 22 at an end portion separated from the holding portion 18, and the frame 14 can be fixed to the soot tube 8 via the fixing portion 22. In the present embodiment, the free end side that is separated from the support leg portion 20 is fixed to the rod tube 8 in a state where it is disposed on the original side, that is, the fishing reel side. The fixing portion 22 has a plate shape having a width smaller than the outer diameter of the soot tube 8 to be attached, and the back surface 24 opposite to the support leg portion 20 is placed on the soot tube 8. Form a surface.

  The surface 26 on the side of the support leg 20 is formed on an inclined surface that is inclined toward the back surface 24 on the free end side that is separated from the support leg 20, but gradually toward the side of the tub tube 8 along the longitudinal direction of the fixing part 22. You may form in the curved surface shape which curves. In addition, the surface 26 may have a curved shape that is gradually curved toward the side tube 8 toward the side edge along the width direction of the fixing portion 22. By forming the surface 26 of the fixing portion 22 in such a curved surface shape, it is possible to form a smooth outer surface having no corners or protrusions that easily catch a fishing line when fixed to the rod 8. , Winding and threading are easy.

  The back surface 24 of the fixing portion 22 can be formed as a flat surface, but as shown in FIG. 2, the mounting surface is formed as a curved surface along the outer surface of the soot tube 8 so that the mounting surface is the soot tube 8. The outer surface shape is suitably adapted to improve the fixing force with respect to the soot tube 8.

  In this way, the fixed side bent portion 28 and the holding side bent portion 30 are provided on the support leg portion 20 that connects the fixed portion 22 and the holding portion 18 and arranges the holding portion 18 in a required direction and position. By adjusting the bending angles of these bent portions 28 and 30, the posture of the holding portion 18 and the guide ring 12 with respect to the fixed portion 22 can be changed. The guide ring 12 shown in FIG. 1 has a central axis O arranged in parallel to the axis C of the soot tube 8, and can be oriented in various directions without being limited to this by adjusting the bending angle. Obviously we can do it.

  The inclination angle α1 of the fixed side bent portion 26 formed between the support leg portion 20 and the fixed portion 22 is in the range of 30 to 90 degrees, and the holding side bent portion 30 is the intermediate portion 21 of the support leg portion 20 and the holding portion. It is preferable that the inclination angle α2 with respect to 18 is in the range of 0 to 45 degrees, and the angle obtained by adding both inclination angles, that is, the angle of the holding part 18 with respect to the fixed part 22 is 30 degrees or more and 100 degrees or less.

  The frame 14 having the structure as described above is formed of a laminated molding material 32 in which at least a part including the fixing portion 22 is formed by laminating a fiber reinforced prepreg in which a reinforced fiber is impregnated with a synthetic resin into a plate shape. When the entire frame 14 is formed of the laminated molding material 32, the manufacturing process is simplified and the frame 14 can be formed into a lightweight structure.

  FIG. 3 shows an example of a laminated structure of the laminated molding material 32 that orients the reinforcing fibers in various directions. Such a laminated molding material 32 can be formed by laminating a plurality of fiber-reinforced prepregs impregnated with a thermosetting resin such as an epoxy resin as a matrix resin on a reinforcing fiber such as carbon fiber or glass fiber. It is also possible to use a thermoplastic resin instead of the thermosetting resin.

  In the laminated molding material 32, a fiber reinforced resin layer 32 in the longitudinal direction along which the reinforcing fibers extend along the longitudinal direction of the fixing portion 22 is arranged at the center in the thickness direction, and the reinforcing fibers are arranged above and below the longitudinal direction of the fixing portion 22. The fiber reinforced resin layers 36 and 38 in the cross direction oriented in the direction crossing the fiber are arranged, and the woven fabric layers 40 and 40 woven with the reinforcing fibers are arranged outside the fiber reinforced resin layers in the cross direction. It is. A symbol M indicates a neutral surface in the thickness direction of the laminated molded body 30.

  As shown in FIGS. 1 and 2, the fixing portion 22 is not only formed in an elongated plate shape along the axis C of the soot tube 8, but, for example, the circumferential dimension of the soot tube 8 is the soot tube. It is also possible to form it so that it may become longer than the axial length direction of 8, or it is also possible to form the bending part 28 in the shape of a smooth curve.

  The longitudinal fiber reinforced resin layer 34 disposed at the center in the thickness direction improves the bending balance of the rod tube 8 and improves the strength and stability of the rod tube 8 and the fishing guide 10. It is preferable to form the reinforcing fiber having an elastic modulus (tensile elastic modulus) smaller than the elastic modulus (tensile elastic modulus) of the reinforcing fiber in the axial length direction. Furthermore, most of the reinforcing fibers (for example, 50% or more or 70% or more) arranged in the fixed portion have an elastic modulus (tensile elasticity) smaller than the elastic modulus (tensile elastic modulus) of the reinforcing fibers in the axial direction of the tub tube 8. It is preferable to form the reinforcing fiber having a ratio).

  The fiber reinforced resin layer 34 is formed by stacking a plurality of fiber reinforced prepregs in which reinforcing fibers are aligned in one direction at an angle of 0 ° ± 5 ° (or 0 ° ± 10 °) with respect to the axial length direction of the tub tube 8. It is preferable to form them.

  The fiber reinforced resin layers 36 in the intersecting direction are each oriented in a direction intersecting at a preferred angle of approximately 45 degrees within a range of 25 to 65 degrees with respect to the longitudinal direction of the fixed portion 22 and oriented in opposite directions. The inner oblique fiber layer 36a and the outer oblique fiber layer 36b are formed. Similarly, the cross-direction fiber reinforced resin layer 38 disposed on the opposite side across the longitudinal fiber reinforced resin layer 34 is also approximately 45 in the range of 25 to 65 degrees with respect to the longitudinal direction of the fixing portion 22. It has an inner oblique fiber layer 38a and an outer oblique fiber layer 38b that intersect at a preferred angle and are oriented in opposite directions.

  The oblique fiber layers 36 a, 36 b, 38 a, 38 b of the fiber reinforced resin layers 36, 38 are reinforced fibers of 45 ° ± 15 ° (or 45 ° ± 30 °) with respect to the axial length direction of the soot tube 8. It is preferable to form a fiber reinforced prepreg aligned in one direction at an angle so as to overlap the fiber reinforced resin layer 34 at the center.

  By disposing the fiber reinforced resin layers 36 and 38 in the intersecting direction on both sides in the thickness direction of the fiber reinforced resin layer 34 in the longitudinal direction, the weight of the fishing line guide 10, particularly the fixing portion 10 is reduced, and the strength is improved and stabilized. Can be achieved.

  The fiber amount of the reinforcing fiber formed by the fiber reinforced resin layers 36 and 38 in the crossing direction and the woven fabric layer 40 to be described later should be at least half (1/2 or more) of the entire reinforcing fiber amount forming the fixing portion 22. Thus, when attached to the soot tube 8, the bending balance of the soot tube 8 can be improved, the stress concentration can be relaxed, and the strength can be improved.

  The woven fabric layer 40 disposed outside the fiber reinforced resin layers 36 and 38 in the cross direction can be formed by weaving, for example, fiber bundles composed of a plurality of reinforcing fibers in a cross shape as the reinforcing fibers. As the weaving structure of the woven fabric layer 40, various woven structures such as a biaxial woven fabric combining fiber bundles extending in two directions or a triaxial woven fabric combining fiber bundles extending in three directions are formed. It is possible. In any case, the direction of the main fibers or fiber bundles of the fabric layer 40 is inclined with respect to the longitudinal direction of the fixing portion 22 (in the range of 45 ° ± 15 ° or 45 ° ± 30 °) and is relative to the longitudinal direction. It is preferable to arrange them symmetrically.

  The woven fabric layer 40 includes reinforcing fibers (fiber bundles) extending at an angle of 45 ° ± 15 ° with respect to the axial length direction and reinforcing fibers (fiber bundles) extending at an angle of 0 ° to 70 ° with respect to the axial length direction. ) And a fiber reinforced prepreg formed by weaving. The fiber reinforced prepreg forming the woven fabric layer 40 has a resin content (RC: wt%) greater than that of the fiber reinforced prepreg in the axial length direction forming the fiber layer 34 in the axial length direction.

  The woven fabric layer 40 is preferably formed so that the size of the stitch formed by the fiber bundles crossing each other is smaller than the minimum width portion of the support leg portion 20 (for example, the portions on both sides of the recess 20b). In particular, it is preferable to reduce the size of the stitches at the bent portion 28 and similarly at the portions of the fixing portion 22 and the holding portion 18.

  By disposing such a woven fabric layer 40 on the outermost side, it is possible to prevent the reinforcing fibers from peeling from the outer layer and to stabilize the strength.

  The reinforcing fibers that form the fiber reinforced resin layers 36 and 38 in the cross direction may have the same elastic modulus as the reinforcing fibers that form the fiber reinforced resin layer 34 in the longitudinal direction.

  When the fiber bundle of the woven fabric layer 40 is formed by combining fiber bundles extending in many directions of three or more directions, the fiber reinforced resin layer 34 in the longitudinal direction is omitted, and the laminated molding material 32 It is also possible to form all the fiber reinforced resin layers with the woven fabric layer 40.

  When manufacturing the frame 14 from such a laminated molding material 32, a fiber reinforced prepreg sheet (not shown) forming the fiber reinforced resin layers 34, 36, and 38 and the woven fabric layer 40 is cut into a predetermined shape, The fiber direction is overlapped along each fiber direction of the laminated molding material 32 described above. The number of fiber-reinforced prepreg sheets or the number of layers to be laminated can be arbitrarily adjusted according to the type of fiber-reinforced prepreg sheets and the conditions for stacking. For example, the entire required amount of the laminated molding material 32 is overlapped. However, by dividing into a plurality of times, it can be set with high accuracy in a mold (not shown) in a state in which the movement of the reinforcing fibers in each fiber-reinforced prepreg sheet is reduced.

  The fiber reinforced prepreg sheets may be set on the mold in a state of being overlapped in advance, or may be set one by one in order. After the fiber reinforced prepreg is set in one of the molds, the fiber reinforced prepreg is pressurized with the other mold, and both molds are fixed integrally. At this time, the bent portions 28 and 30 are formed in the fiber-reinforced prepreg sheet in an uncured state (including after temporary curing) and held in a shape corresponding to the shape of the frame 14. Thereby, generation | occurrence | production of the internal residual stress after shaping | molding can be prevented, and a strength improvement and stabilization can be aimed at. Thereafter, the fiber-reinforced prepreg sheet is heat-cured and taken out from the mold as a laminated molding material 32 molded into a predetermined shape.

  The laminated molding material 32 taken out from the mold is formed, for example, as a strip-shaped plate having a constant thickness, and is formed in a state in which a large number of parts to be formed on the frame 14 are connected. Each frame 14 can be cut out and processed from the plate-like body by an appropriate method such as press working, cutting out by ejecting fluid such as a water jet, or cutting out using a cutting tool such as an end mill.

  The frame 14 thus formed is not limited to a plate-like shape having the same thickness, but the thickness, the amount of reinforcing fibers, or the tensile elastic modulus can be changed or adjusted depending on the part. The adjustment of the thickness, the amount of reinforcing fibers, or the tensile elastic modulus can be adjusted by variously changing the laminated thickness or the fiber reinforced prepreg to be laminated when forming the plate-like body.

  When processing each frame 14 from this plate-shaped body, it is preferable to process the holding hole 16 of the holding part 18 and the recess 20b of the support leg part 20 simultaneously. If necessary, after the frame 14 is cut out, the holding holes 16 and the recesses 20b may be processed.

  As shown in FIG. 4, the holding hole 16 has, on the inner peripheral surface 16a, a protrusion 42 that contacts the outer peripheral surface 12b of the guide ring 12, and concave portions 44 and 46 that are not in contact with the outer peripheral surface 12b. It is formed along the front-rear direction, that is, the fitting direction H of the guide ring 12 with respect to the holding hole 16. The non-contact means a state in which the support function for the holding portion 18 is not exhibited when the guide ring 12 is held by contacting the outer peripheral portion 12b with the protrusion 42 of the holding hole 16, and a gap is formed. For example, a state in which a substantial support function is not exhibited even in a physically contacted state is included.

  In the present embodiment, the projecting portion 42 is a concave portion 44 formed by a conical surface facing in the opposite direction when viewed in the axial sectional view (FIG. 4) of the holding portion 18 along the central axis of the holding hole 16. Projecting inward in the radial direction as a top portion between 46, a continuous ridge is formed along the circumferential direction of the inner peripheral surface 16 a of the holding hole 16. The inner diameter R of the protrusion 42 is formed to be slightly smaller than the outer diameter of the guide ring 12, and when the guide ring 12 is correctly fitted to the holding hole 16 in a predetermined direction, the protrusion 42 frictionally engages with the outer peripheral surface 12 b of the guide ring 12 to securely hold the guide ring 12. This predetermined direction is the orientation direction of the central axis O of the inner peripheral surface 12a of the guide ring 12 with respect to the axis C of the rod tube 8, and is not limited to the direction parallel to the axis C, and preferably guides the fishing line. For example, it may be inclined about 50 ° to 80 ° with respect to the axis C.

  As long as such a protrusion 42 protrudes from the inner peripheral surface 16a of the holding hole 16, it can be formed at an appropriate position between the front surface 19a and the rear surface 19b of the holding portion 18. In order to prevent damage from the protrusions such as peeling of the fiber reinforced layer due to the action of the load, the front surface 19a and the rear surface 19b are not disposed in the same plane as the front surface 19a and the rear surface 19b of the holding portion 18. It is preferable to arrange in the intermediate part along the central axis O of the holding hole 16 between the two.

  In the present embodiment, the neutral surface M of the laminated molding material 32 is disposed at the center position along the axial direction between the front surface 19a and the rear surface 19b of the holding portion 18, and the rear surface is located behind the neutral surface M. It arrange | positions in the oblique fiber layer 36a36b biased to the 10b side. In this case, when the guide ring 12 is fitted into the holding hole 16, the guide ring 12 can be guided using the width of the recess 46 on the front surface 19b side, that is, the inclined surface in the central axis direction. 12 can be easily mounted. Furthermore, even if the protrusion 42 is pressed by the guide ring 12, the guide ring does not hit the woven fabric layer 40, and the outermost woven fabric layer 40 can prevent the reinforcing fibers from peeling and stabilize the strength. .

  In any case, it is preferable that the protrusion 42 is disposed in a plane parallel to the neutral plane M. Thereby, the protrusion 42 is arranged at the same position along the axial direction of the central axis O along the circumferential direction of the inner peripheral surface 16a of the holding hole 16, and the outer peripheral surface 12b of the guide ring 12 is pivoted. It can hold | maintain in the same position along a direction, and can hold | maintain the guide ring 12 more reliably.

  In FIG. 4, the protrusion 42 is formed along the boundary surface between the oblique fiber layers 36a and 36b, but it is obvious that the protrusion 42 may be formed in one fiber layer. The concave portions 44 and 46 are formed as frustoconical curved surfaces, but the curved surfaces forming these concave portions 44 and 46 are curved in a convex or concave shape with respect to the direction of the central axis O. Also good.

  When the guide ring 12 is fitted along the fitting direction H using an appropriate method such as press-fitting, bonding, curling, or the like in the holding hole 16 in which the inner peripheral surface 16a is formed, the protrusion 42 is guided. The outer peripheral surface 12b of the ring 12 is pressed and held from the circumferential direction. Since the protrusion 42 is disposed substantially parallel to the neutral surface M, the guide ring 12 is held in a state where the central axis O is disposed coaxially with the central axis of the holding hole 16. The recesses 44 and 46 are maintained in a non-contact state with respect to the outer peripheral surface 12b. The lengths of the guide ring 12 projecting from the front surface 19a and the rear surface 19b of the holding portion 18 are preferably the same, but one projecting amount may be increased.

  As shown in FIG. 5, when the guide ring 12 is held by the protrusion 42, the frame 14 is formed in the gap S formed between the concave portions 44 and 46 of the inner peripheral surface 16a and the outer peripheral surface 12b. A fixing member 48 formed of a material softer than the above-described matrix resin of the laminated molding material 32 is disposed, and is bonded and fixed to the guide ring 12 and the holding portion 18.

  As described above, when the fixing member 48 is arranged so as to fill the gap S, when the holding portion 18 of the frame 14 is bent and deformed by an external force, for example, the fixing member 48 is elastically deformed and the holding portion is deformed. Can be absorbed. Thereby, the guide ring 12 is reliably held without changing the posture held by the protrusion 42.

  Such a fixing member 48 is preferably formed of, for example, an epoxy resin adhesive, an acrylic resin adhesive, a cyanoacrylate adhesive, or the like. By forming such a fixing member 48, the guide ring 12 is stabilized. Can be held. The guide ring 12 is supported by the fixing member 48 with a buffering effect. Note that epoxy-modified silicon, acrylic-modified silicon, modified acrylic resin, or the like can be used as the fixing agent 48.

  In the fishing line guide 10 of this embodiment formed in this way, since the frame 14 is formed of fiber reinforced resin, the fishing line guide 10 is reduced in weight, the external force acting on the frame 14 is reduced by bending, and the frame 14 Thus, the fixing member 48 absorbs the bending deformation of the guide ring 12 to securely hold the guide ring 12 and to prevent the drop off.

  When the fixing member 48 covers the inner peripheral side surfaces of the front surface 19a and the rear surface 19b adjacent to the holding hole 16 as indicated by reference numeral 48a in FIG. 5, a gap is provided between the guide ring 12 and the holding portion 16. Even when is formed, it is possible to reliably prevent the fishing line from entering the gap.

  Furthermore, the protrusions 42 are arranged at the same axial position along the circumferential direction of the inner circumferential surface 16a of the holding hole 16, so that the outer circumferential surface 12b of the guide ring 12 is evenly arranged at the same position along the axial direction. The guide ring can be held more reliably.

  6 and 7 show a fishing line guide 10A according to another embodiment.

  Since the fishing line guide 10A of this embodiment is substantially the same as the fishing line guide 10 described above, the same parts are denoted by the same reference numerals, and detailed description thereof is omitted.

  The fishing line guide 10 </ b> A of the present embodiment has a plurality of support portions 50 projecting radially inward from the inner peripheral surface 16 a of the holding hole 16 along the circumferential direction. The portion 42 and the concave portions 44 and 46 are formed along the direction of the central axis O of the guide ring 12. Although these support parts 50 are arrange | positioned at six site | parts which oppose to radial direction, if it is three or more sites | parts, it can be made into an appropriate number. These support parts 50 are preferably arranged at equal intervals along the circumferential direction in order to hold the guide ring 12 evenly.

  As shown in FIG. 6, each support portion 50 is formed in a tapered shape in which the circumferential dimension gradually decreases from the inner peripheral surface 16 a side inward in the radial direction. Opposing side surfaces are formed as curved surfaces that are smoothly continuous radially inward from the inner peripheral surface 16a. An axial groove 52 is formed between these side surfaces, and the above-described fixing member 48 is filled in the axial groove 52. Also in this case, it is preferable to cover the inner peripheral side surfaces of the front surface 19a and the rear surface 19b adjacent to the holding hole 16 with the fixing member 48a to prevent the fishing line from entering.

  As described above, a plurality of support portions 50 project radially inward along the circumferential direction on the inner peripheral surface 16 a of the holding hole 16, and the protrusions 42 and the recesses 44 and 46 are formed on the support portion 50. In this case, even when the holding portion 18 is bent and deformed along the radial direction of the holding hole 16, the bending deformation is absorbed by the axial groove 52. For this reason, the protrusion 42 formed in each support part 50 holds the guide ring 12 reliably.

  The protrusions 42 formed on the respective support portions 50 are preferably arranged at the same position along the central axis O along the inner peripheral surface 16a of the holding hole 16, whereby the outer peripheral surface 12 b of the guide ring 12 is arranged. The guide ring 12 can be more reliably held at the same position along the axial direction and more reliably.

  As the fishing line guides 10 and 10A formed in this way are separated from the fishing reel, the sizes of the holding portion 18 and the guide ring 12 are reduced, and the axis C of the rod 8 and the central axis O of the guide ring 12 are reduced. The distance between is also reduced. The arrangement position of the protrusions 42, the amount of protrusion from the inner peripheral surface 16a, and when the protrusions 42 are formed on the plurality of support parts 50, the number of the support parts 50 are also appropriately changed according to the size of the guide ring 12. can do.
