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 fishing line guides, the outer periphery of the guide ring is engaged with and held by a protrusion that protrudes toward the inner peripheral side of the metal stationary ring, and is fixed to the fishing rod with mounting legs extending forward and backward from the stationary ring. (For example, refer to Patent Document 1).

  This fishing line guide has been used before that because the guide ring is held by the protrusion of the metal fixed ring, a gap is formed between the inner periphery of the fixed ring and the outer periphery of the guide ring. The cushioning material is omitted and it functions as a protective ring.

Japanese Utility Model Publication No. 53-147268

  However, when the frame made up of the fixed ring and the mounting leg for fixing the guide ring is made of metal, the fishing line guide becomes heavier as a whole, and the rod pipe may be deformed and damaged when it is attached to the fishing rod. Furthermore, in order to fix to a fishing rod via an attachment leg, it cannot bend according to the tone of a fishing rod, and the original tone of a fishing rod will be inhibited.

  Although it is conceivable to form such a frame with a thermoplastic synthetic resin mixed with particles and short fibers instead of such a metal, it is difficult to hold the guide ring firmly, and it is used for a long time Thus, it is conceivable that the portion that supports the guide ring deteriorates or sags, and the guide ring is easily detached.

  This invention is made | formed based on such a situation, and it aims at providing the fishing line guide which has a flame | frame made from fiber reinforced resin which a guide ring cannot remove | deviate easily.

  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 holding the guide ring in a holding portion, A fishing line guide is provided in which the reinforcing fibers in the fiber reinforced resin are exposed on the inner peripheral surface of the holding hole, and the reinforcing fibers contact the outer peripheral surface of the guide ring.

  It is preferable that the reinforcing fibers exposed on the inner peripheral surface of the holding hole abut from a direction orthogonal to or inclined from the outer peripheral surface of the guide ring.

  Moreover, it is preferable that the reinforcing fiber that has contacted the outer peripheral surface of the guide ring is in contact in a direction along the outer peripheral surface of the guide ring.

  A plurality of support portions projecting radially inward along the circumferential direction on the inner peripheral surface of the holding hole, and the guide ring may be held in the holding hole by these support portions. .

  It is preferable that the support position of the guide ring by the support portion is located at least three times the diameter of the reinforcing fiber from the front or rear surface of the frame along the direction of the central axis of the guide ring.

  Furthermore, it is preferable to arrange a fixing agent between the inner peripheral surface of the holding hole and the outer peripheral surface of the guide ring.

  Moreover, it has a thin resin layer arrange | positioned between the inner peripheral surface of the said holding hole, and the outer peripheral surface of a guide ring, This thin resin layer may have a part which the said reinforced fiber contact | abuts. .

  The guide ring has a concave portion extending in the circumferential direction on the outer peripheral side, the concave portion is filled with fiber reinforced resin, and the holding portion is integrally formed on the outer side of the filled fiber reinforced resin. May be.

  According to the fishing line guide of the present invention, the reinforcing fiber exposed on the inner peripheral surface of the holding hole comes into contact with the outer peripheral surface of the guide ring, so that the guide ring is stably held.

  When the reinforcing fiber comes into contact with the outer peripheral surface of the guide ring from a direction orthogonal to or inclined, the force in various directions can be held between the guide ring and the frame using the reinforcing fiber. And the holding power can be improved.

  When the reinforcing fiber is in contact with the guide ring in the direction along the outer peripheral surface, the tip of the reinforcing fiber is in reliable contact with the outer peripheral surface of the guide ring, and the guide ring can be stably supported.

  When the guide ring is held by a plurality of support portions protruding from the inner peripheral surface of the holding hole, the guide ring is securely held even when the holding portion is bent and deformed along the radial direction of the holding hole. be able to.

  When the support position of the guide ring by the support part is located more than 3 times the diameter of the reinforcing fiber from the front or rear surface of the frame along the direction of the central axis of the guide ring, a load acts through the reinforcing fiber. Even in this case, breakage of the frame from the reinforcing fiber can be prevented.

  When a fixing agent is placed between the inner peripheral surface of the holding hole and the outer peripheral surface of the guide ring, the fixing agent also enters between the reinforcing fibers exposed on the inner peripheral surface of the holding hole to prevent the fixing agent from sagging. And can be maintained at the required position.

  In addition, when a thin resin layer is placed between the inner peripheral surface of the holding hole and the outer peripheral surface of the guide ring, the effect of internal stress due to temperature changes and external impacts are alleviated, and the guide ring is stable. Can be held in.

  Furthermore, the guide ring has a concave portion extending in the circumferential direction on the outer peripheral side. When the concave portion is filled with fiber reinforced resin and the holding portion is integrally formed on the outside of the filled fiber reinforced resin, Further, the fishing line guide can be further reduced in weight and size.

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 central axis O of the fishing line conduction 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 (for example, titanium). . 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.

  A film made of metal, ceramics, rigid resin paint or the like may be formed on an appropriate portion of the outer surface including the end surface in the direction of the central axis O of the guide ring 12 for decoration and other purposes.

  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.

  When 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 recessed in one or both along the axial direction of the central axis O of the fishing line conduction hole without being formed through. . 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. 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.

  Although the back surface 24 of the fixing portion 22 can be formed as a flat surface, as shown in FIG. 1, 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 such a structure is a laminated molding material 32 which is a fiber reinforced resin material formed by laminating a fiber reinforced prepreg including at least a part of the fixing portion 22 impregnated with a synthetic resin into a reinforcing fiber. Formed with. 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 34 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 32 or the holding portion 18.

  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).

  This fiber reinforced resin layer 34 is a fiber reinforced prepreg in which reinforced 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 a plurality of layers.

  The fiber reinforced resin layers 36 in the intersecting direction are oriented in directions intersecting with each other in the range of 25 to 80 degrees with respect to the longitudinal direction of the fixed portion 22 and the inner oblique fiber layers 36a are oriented in opposite directions to each other. The outer oblique fiber layer 36b is formed. Similarly, the fiber reinforced resin layer 38 in the cross direction disposed on the opposite side across the fiber reinforced resin layer 34 in the longitudinal direction also intersects the longitudinal direction of the fixing portion 22 in the range of 25 to 80 degrees, respectively. In addition, it has an inner oblique fiber layer 38a and an outer oblique fiber layer 38b that are oriented in opposite directions.

  The oblique fiber layers 36a, 36b, 38a, and 38b of the fiber reinforced resin layers 36 and 38 have the reinforcing fibers aligned in one direction at an angle of 25 ° to 80 ° with respect to the axial length direction of the soot tube 8. It is preferable to form the fiber reinforced prepreg so as to overlap the central fiber reinforced resin layer 34.

  By disposing such fiber reinforced resin layers 36 and 38 in the cross 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, in particular, the fixing portion 22 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 in an angular range of 45 ° ± 15 ° with respect to the axial length direction and reinforcing fibers (fiber bundles) extending in an angular range of 0 ° to 70 ° with respect to the axial length direction. And a fiber reinforced prepreg formed by weaving a fiber bundle). 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.

  A plurality of fiber reinforced prepreg sheets may be set on the mold in a state where they are 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 a projecting portion 42 that abuts on the outer peripheral surface 12 b of the guide ring 12 on the inner peripheral surface 16 a and a part as indicated by reference numeral 37 with respect to the outer peripheral surface 12 b. The non-contact recesses 44 and 46 are formed along the central axis O which is the fitting direction 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 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 into 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 to about 45 ° with respect to the axis C.

  The protrusion 42 preferably has an inner diameter in the range of 0.01 to 0.06 mm in accordance with the outer diameter of the outer peripheral surface 12b of the guide ring 12 as a press-fitting allowance of the guide ring 12, such a range. Thus, even when the guide ring 12 is press-fitted into the holding hole 16, it is possible to prevent the generation of internal stress while maintaining the overall shape of the frame 14.

  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, these front surfaces are arranged in the same plane as the front surface 19a or the rear surface 19b of the frame 14, that is, the holding portion 18. It is preferable to arrange in an intermediate portion along the central axis O of the holding hole 16 between 19a and the rear surface 19b.

  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 layers 36a and 36b biased to the 19b 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 44 on the front surface 19a 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 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. The curved surfaces forming the concave portions 44 and 46 are curved in a convex shape or a concave shape along the direction of the central axis O. There may be.

  When the guide ring 12 is fitted in the holding hole 16 formed with the inner peripheral surface 16a using an appropriate method such as press-fitting, bonding, curling, or the like along the fitting direction, the projecting portion 42 becomes the guide ring. The outer peripheral surface 12b of 12 is pressed and hold | maintained 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 concave portions 44 and 46 are maintained in a non-contact state in principle 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.

  When the guide ring 12 is press-fitted into the holding hole 16 in this way, a part of the inner peripheral surface 16 a of the holding hole 16 is deformed or slipped by contact with the guide ring 12. Thereby, as illustrated by reference numeral 37 in the enlarged portion of FIG. 4, a part of the reinforcing fibers of the fiber reinforced resin constituting the frame 14 is exposed on the inner peripheral surface 16 a. As described above, in addition to the expression by the guide ring 12, the reinforcing surface 37a is exposed to the inner peripheral surface 16a in advance before the guide ring 12 is fitted by roughening the holding surface 16a by an appropriate means. It may be left.

  The exposure includes not only that the reinforcing fibers 37 are arranged in the same plane as the matrix resin of the inner peripheral surface 16a but also a state in which the reinforcing fibers 37 protrude beyond this. The state in which the reinforcing fibers are exposed does not mean a state in which the fiber portion is polished, but may be a state in which a protective coating or the like exists in units of reinforcing fibers. Specifically, even if it has a protective film whose film thickness is equal to or less than the radius of the reinforcing fiber, it is sufficient that the reinforcing fiber is in direct contact with the guide ring 12 substantially.

  The reinforcing fiber 37 exposed on the inner peripheral surface 16a is a reinforcing fiber in the guide frame 14, and in the case where a plurality of fiber-reinforced prepreg sheets are laminated as in the present embodiment, the fibers in the longitudinal direction are used. It is preferable to provide at least three directions of fiber reinforcing layers such as the reinforcing resin layer 34, the reinforcing fiber layers 36 and 38 in the crossing direction, and the woven fabric layer 40 in the vertical and horizontal directions. By doing in this way, according to each orientation direction, the reinforcement resin 37 changes the angle of the holding hole by changing the angle such as the orthogonal direction (range of 90 ° ± 30 °) or the inclination direction (30 ° -60 °). It can be exposed to the inner peripheral surface 16a.

  In the fishing line guide 10 formed in this way, when the guide ring 12 is fitted into the holding hole 16, the protrusion 42 has the matrix resin forming the laminated molding material 32 of the frame 14 on the outer peripheral surface 12 b of the guide ring 12. At the same time, the reinforcing fiber 37 exposed to the inner peripheral surface 16 a by the protrusion 42 and the concave portions 44 and 46 also contacts the outer peripheral surface 12 b of the guide ring 12.

  Therefore, in the fishing line guide 10, the outer peripheral surface 12 b of the guide ring 12 comes into contact with the reinforcing fiber 37 exposed in the protrusion 42 and the recesses 44 and 46 together with the matrix resin of the protrusion 42. Thereby, the contact area of the inner peripheral surface 16a of the holding | maintenance part 16 and the outer peripheral surface 12b of the guide ring 12 will increase substantially, and the guide ring 12 can be supported stably.

  When the reinforcing fiber 37 is bent after coming into contact with the outer peripheral surface 12b of the guide ring 12, and its distal end extends along the outer peripheral surface 12b of the guide ring 12, the reinforcing fiber 37 and the outer peripheral surface of the guide ring 12 are used. Thus, the guide ring 12 can be stably supported.

  Further, the reinforcing fiber 37 exposed to the inner peripheral surface 16a by press-fitting the guide ring 12 comes into contact with the end portion of the exposed reinforcing fiber 37, but the lamination forming material 32 of the frame 14 is It has reinforcing fibers in a plurality of directions in the inclined direction. Therefore, it hits the direction orthogonal to the outer peripheral surface 12b of the guide ring 12, that is, perpendicular to the outer peripheral surface, and also hits the inclined direction. Accordingly, various directions of force can be transmitted through the reinforcing fibers 37 between the guide ring 12 and the holding portion 18 of the frame 14 together with the fixing agent to be described later. Since it is supported from various directions by the reinforcing fibers that come into contact with each other, the holding force of the guide ring 12 can be improved.

  Furthermore, the reinforcing fiber 37 bent along the outer peripheral surface 12b after hitting the outer peripheral surface 12b of the guide ring 12 has a side surface or a side portion of the reinforcing fiber 37 in contact with the outer peripheral surface of the guide ring 12, so that the guide ring The contact area with 12 is increased, and the holding force is further increased. Further, even when only a part of the side portion of the reinforcing fiber 37 is exposed on the inner peripheral surface 16 a and the end portion on the distal end side protrudes into the frame 14, it contacts the outer peripheral surface 12 a of the guide ring 12. The contact area between the reinforcing fiber 37 and the guide ring 12 and the holding force are increased by the contact between the reinforcing fiber 37 and the outer peripheral surface 12 a of the guide ring 12.

  In the present embodiment, as shown in FIG. 4, when the guide ring 12 is held by the protrusion 42, the gap S formed between the recesses 44 and 46 of the inner peripheral surface 16a and the outer peripheral surface 12b A fixing agent 48 formed of a material softer than the laminated molding material 32 forming the frame 14 is disposed.

  As described above, the fixing agent 48 is disposed in a state of filling the gap portion S, so that the fixing agent adheres to the guide ring 12 and the holding portion 18. For example, when the holding portion 18 of the frame 14 is bent and deformed by an external force, the fixing agent 48 is elastically deformed and can absorb the deformation of the holding portion. Thereby, the guide ring 12 is reliably held without changing the posture held by the protrusion 42. By allowing the fixing agent 48 to enter between the exposed reinforcing fibers 37, it is possible to prevent the fixing agent from sagging and to maintain the fixing agent 48 in a required position.

  In addition, since the fixing agent 48 is filled together with the reinforcing fibers 37 exposed on the inner peripheral surface 16a in the recesses 44 and 46, the fixing agent 48 is strengthened to securely hold the guide ring 12, and the fixing agent 48 itself Deterioration is also prevented.

  The fixing agent 48 is 50% or more with respect to the volume of the gap S between the inner peripheral surface 16a of the holding hole 16 and the outer peripheral surface 12b of the guide ring 12, and is ½ along the circumferential direction of the holding portion 18. It is preferable to arrange over the above range. As a result, it is possible to reliably prevent the guide ring 12 from falling off while holding the guide ring 12 in a buffered manner.

  Such a fixing agent 48 is preferably formed of, for example, an epoxy-based adhesive, an acrylic-based adhesive, a cyanoacrylate-based adhesive, or the like, and by forming such a material, the guide ring 12 is held in a buffer manner. However, it is possible to prevent the dropout. Note that epoxy-modified silicon, acrylic-modified silicon, modified acrylic resin, or the like can be used as the fixing agent 48.

  In addition, since the fishing line guide 10 of the present embodiment has the frame 14 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 is bent and deformed. Can be absorbed by the fixing agent 48 and the guide ring 12 can be securely held, and can be reliably prevented from falling off.

  When the fixing agent 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. 4, a gap is formed between the guide ring 12 and the holding portion 16. Even when is formed, the fishing line can be reliably prevented 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.

  5 and 6 show a fishing line guide 10A according to another embodiment. Since the fishing line guide according to various embodiments or modifications described below 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.

  A fishing line guide 10A shown in FIGS. 5 and 6 has a plurality of support portions 50 projecting radially inward from the inner peripheral surface 16a of the holding hole 16 along the circumferential direction. The protrusion 42 and the recesses 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.

  The protrusions 42 formed on these support portions 50 are located at a position where the guide ring 12 is supported from the front surface 19a or the rear surface 19b of the frame 14 along the direction of the central axis O, that is, at least 3 of the diameter of the reinforcing fiber. It is preferably formed so as to be at a position that is at least double, preferably at least 5 times inside, that is, on the neutral plane M side. In this case, the guide ring 12 can be reliably contacted and reliably held.

  As shown in FIG. 5, each support part 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 the side surfaces, and the fixing agent 48 can be 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 agent 48a to prevent the fishing line from entering.

  As shown in FIG. 6, each support portion 50 is formed with a protrusion 42 and recesses 44 and 46 along the direction of the central axis O. The reinforcing fiber 37 is exposed at the protrusion 42.

  The reinforcing fiber 37 exposed to the protrusion 42 is due to the matrix resin at the tip of the protrusion 42 being retracted when the guide ring 12 is press-fitted. It is not necessary to roughen the inner peripheral surface 16a in advance.

  The reinforcing fibers 37 may be exposed only at the distal ends of the protrusions 42, or after contacting the guide rings 12 according to the press-fitting direction of the guide rings 12 at the distal ends of these reinforcing fibers 37, the same along the guide rings 12. Bent in the direction.

  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.

  7 to 9 show a fishing line guide 10B according to still another embodiment.

  As shown in FIG. 7, the frame 14 in this embodiment extends fiber bundles 54, 56, 58, and 60 made of a large number of reinforcing fibers while curving along the peripheral portion of the holding hole 16, and these fibers. A holding portion 18 made of a fiber reinforced resin in which a bundle is impregnated with a synthetic resin 55 is formed. The fiber bundle may be formed as a bundle-shaped prepreg impregnated with a synthetic resin in advance. In FIG. 7, the fiber bundles 54 and 56 laminated on the inner peripheral side and the fiber bundles 58 and 60 laminated on the outer peripheral side are arranged so as to overlap each other in the radial direction, but the inner peripheral surface 16a is smooth. As long as it forms in a simple curved surface, the whole may be formed by one fiber bundle, and an arbitrary number of fiber bundles can be formed by overlapping.

  Such a fiber bundle does not need to be formed with a constant diameter or cross-sectional shape along its length direction. For example, the diameter or thickness is changed, and a part of the fiber bundle is formed into a sheet shape. It can also be changed as needed. It is preferable that at least a part of the reinforcing fiber 57 in the fiber bundle is continuous with the support leg portion 20 and the fixing portion 22 (FIGS. 1 and 2).

  The reinforcing fiber 57 forming such a fiber bundle is a long fiber used for a fiber reinforced prepreg, and is formed of carbon fiber, glass fiber, aramid fiber, etc., which can be bent with a small bending radius, for example. Is preferred. The synthetic resin 55 forming the matrix resin is preferably a thermosetting resin such as an epoxy resin or an unsaturated polyester, or a thermoplastic resin such as polyamide or PPS.

  In the holding portion 18 of the present embodiment, the reinforcing fibers 57 of the inner fiber bundles 54 and 56 are exposed on the inner peripheral surface 16 of the holding hole 16 along the circumferential direction. And the holding hole 62 opened to the inner peripheral surface 16a is formed in the neutral surface M or its vicinity, The protrusion 64 (FIG. 8, 9) mentioned later of the guide ring 12 is accommodated in this holding hole.

  The outer peripheral surface 12b of the guide ring 12 is formed in a medium-high structure, and has a large-diameter portion 12b1 disposed in the central portion and a small-diameter portion 12b2 sandwiching the central surface. The large diameter portion 12b1 is formed by a cylindrical surface having the maximum diameter d1, and the small diameter portion 12b2 is formed by a curved surface extending from the large diameter portion 12b1 to the end surface of the guide ring 12, and between the front and rear end surfaces. A ridge line portion having an outer diameter d2 is formed.

  A plurality of protrusions 64 protrude from the large-diameter portion 12b1 at intervals along the circumferential direction outward in the radial direction. This protrusion may be formed in a truncated cone shape as shown in FIG. 8, or may be formed in a ridge shape extending in the circumferential direction. Moreover, it is preferable to form the ridgeline part of the outer diameter d2 formed between the small diameter part 12b2 and the axial end surface of the guide ring 12 with a curved surface so as not to damage the fishing line. In such a small diameter portion 12b2, a plurality of concave portions (not shown) formed by, for example, depressions or slits can be provided at intervals along the circumferential direction. The reason why the gap is arranged between the adjacent recesses is to prevent the strength reduction of the guide ring 12 due to continuous formation.

  Such a guide ring 12 can be fixed to the holding portion 18 of the frame 14 by an appropriate method. For example, when the frame 14 is molded with a mold, the guide ring 12 is placed in the mold in advance, and then a fiber bundle impregnated with a synthetic resin or a prepreg tape impregnated with a synthetic resin is installed and pressurized. The guide ring 12 may be fixed to the holding hole 16 with a fixing agent such as an adhesive after the frame 14 is formed. Note that such a fixing agent is disposed in the gap S between the concave portion of the small diameter portion 12b2 and the inner peripheral surface 16a, for example, even when the guide ring 12 is integrally formed on the frame 14 with a mold. Etc., may be used as appropriate.

  In the guide ring 12 fixed to the holding portion of the frame 14 in this way, the reinforcing fiber 57 exposed on the inner peripheral surface of the holding hole 16 contacts the large diameter portion 12b1 of the outer peripheral surface 12b. Thereby, the guide ring 12 is stably held. In particular, the reinforcing fiber 57 extends in the circumferential direction, so that the guide ring 12 is stably held along the circumferential direction. Further, the protrusion 64 accommodated in the holding hole 62 is firmly held between the reinforcing fibers 57, and the integrity of the frame 14 and the guide ring 12 can be ensured.

  Further, the small-diameter portion 12b2 is covered with the matrix resin 55 of the fiber bundle or an adhesive, and is integrated with the inner peripheral surface of the holding hole 16, thereby absorbing the deformation of the holding portion with its elasticity. Can be held stably.

  The large-diameter portion 12b1 and the small-diameter portion 12b2 of the outer peripheral surface 12b are for explanation. If the projection 64 can be formed, the large-diameter portion and the small-diameter portion are strictly partitioned. This is not necessary, and the entire outer peripheral surface 12b can be formed of a curved surface that bulges outward and curves. Further, the protrusion 64 can be arranged at a position biased forward or backward with respect to the neutral surface M.

  FIG. 10 shows a fishing line guide 10C according to still another embodiment.

  In this embodiment, a thin resin layer 66 is disposed between the inner peripheral surface 16 a of the holding hole 16 and the outer peripheral surface 12 b of the guide ring 12.

  The guide ring 12 is formed in the same manner as in the embodiment shown in FIGS. 7 to 9, the outer peripheral surface 12 b has a large diameter portion 12 b 1 and a small diameter portion 12 b 2, a protrusion is formed on the large diameter portion 12 b 1, and the small diameter It is preferable that a recess is formed in the portion 12b2. By forming the outer peripheral surface 12b of the guide ring 12 in such a medium-high structure, it is reliably held by the thin resin layer 66 so as not to be detached from the holding hole 16 having the cylindrical inner peripheral surface 16a.

  The thin resin layer 66 is integrally bonded to the reinforcing fibers exposed on the inner peripheral surface 16 a of the holding hole 16. A part of the reinforcing fibers bonded to the thin resin layer 66 can be further brought into contact with the outer peripheral surface 12b of the guide ring 12, whereby the guide ring 12 can be stably held. In addition, when the reinforcing fiber of the holding part 18 is not exposed to the inner peripheral surface 16a of the holding hole, or when the exposure is small, the reinforcing fiber is exposed by roughening the inner peripheral surface 16a. Also good.

  For example, the thin resin layer 66 is preferably formed so that the thickness g at the thinnest position in the neutral plane M is 0.3 mm or less, specifically, the thickness g is in the range of 5 μm to 100 μm.

  By disposing such a thin resin layer 66 between the holding portion 18 and the guide ring 12, the influence of the internal stress in the guide ring 12 and the frame 14 due to temperature change, the guide ring 12 and the holding portion 18 are The impact acting from the outside can be reduced and the guide ring 12 can be held in a stable state. In particular, when the reinforcing fiber of the holding portion 18 contacts the outer peripheral surface 12b of the guide ring 12, stable holding of the guide ring 12 is ensured.

  The thin resin layer 66 can be placed in the mold and simultaneously molded with the frame 14 in a state where the outer peripheral surface 12b of the guide ring 12 is coated with a resin or wound with a resin film. Alternatively, after the frame 14 is molded, the guide ring 12 may be disposed at a required position in the holding hole 16, and thereafter, the gap (not shown) may be filled with a fixing agent.

  The frame 14 may be formed of a laminated molding material 32 in which prepreg sheets as shown in FIG. 3 are laminated, and fiber bundles 54 and 56 as shown in FIG. 7 are wound along the peripheral portion of the holding hole 16. May be formed. When the laminated molding material 32 is used, the central fiber reinforced resin layer 34 may be formed of two fiber reinforced resin layers 34a and 34b, and a protrusion 64 (FIG. 9) is formed between the two adjacent layers. ) In which the reinforcing fibers in each fiber layer are bent can be prevented from being disturbed. These fiber reinforced resin layers 34a and 34b may be formed of a resin layer in which reinforcing fibers extend in the longitudinal direction, or may be formed of a resin layer extending in a direction opposite to each other.

  The thin resin layer 66 may be formed of, for example, an epoxy resin, a urethane resin, or an acrylic resin, and is preferably formed of a resin material that is more flexible than the frame 14. In addition, the thin resin layer 66 may be reinforced by mixing various types of reinforcing materials such as long fibers, short fibers, whiskers, or particles into the thin resin layer 66. As a specific example of such a reinforcing material, a material that does not corrode (oxidize), such as carbon, glass, or sand, can be used.

  FIG. 11 shows a fishing line guide 10D according to still another embodiment.

  In this embodiment, a groove-like recess 68 extending in the circumferential direction is formed on the outer peripheral surface 12 b of the guide ring 12, and an inner layer portion 70 filled with fiber reinforced resin is formed in the recess 68. The guide ring 12 is integrated with the inner circumferential surface 16 a of the holding hole 16 of the frame 14 together with the inner layer portion 70. As a result, the guide ring 12 is held by two fiber reinforced resin layers of the inner layer portion 70 in the recess 68 and the outer layer portion 72 surrounding the inner peripheral surface 16a of the holding hole 16.

  The concave portion 68 is formed as an annular concave surface having the smallest outer diameter d2 in the neutral surface M of the holding portion 18, and forms a small diameter portion 12b2 in the outer peripheral portion 12b of the guide ring 12. Before and after the concave portion 68, an annular convex surface adjacent to the end surface forms two large-diameter portions 12b1. These large diameter portions 12b1 are formed with curved surfaces having a smaller radius than the small diameter portion 12b2 in the axial cross section shown in FIG. That is, the axial dimension w1 which is the width of the large diameter part 12b1 is preferably smaller than the axial dimension w2 of the small diameter part 12b2, and the width w2 of the small diameter part is used to form the fishing line guide surface 12a larger. The width of the guide ring w3 is preferably 1/4 to 3/4. In addition, the radial dimension T, which is the thickness of the guide ring 12 and the outer layer portion 72, with respect to the width w3 of the guide ring is formed in a relationship of 0.7 W ≦ T ≦ 1.7 W in order to reduce the size and weight. It is preferable.

  The guide ring 12 has a depth t2 larger than the wall thickness t1 in the neutral surface M of the holding portion 18 (t1 <t2), and the thickness of the outer layer portion 72, that is, the radial dimension t4, It is preferable that the height t3 from the fishing line guide surface 12a to the outer edge of the large diameter portion 12b1 is large (t3> t4).

  By forming such a recess 68, the guide ring 12 can be thinned while maintaining the strength, and the fishing line guide 10D can be further reduced in weight and size.

  The guide ring 12 having such a recess 68 is separated from the frame 14 after the fiber reinforced resin forming the inner layer portion 70 is wound in the recess 68 in advance, and the guide ring 12 is disposed in the mold. In addition, the guide ring 12 and the inner layer part 70 can be integrated. Thereafter, the guide ring 12 in which the inner layer portion 70 is integrated can be disposed in the mold together with the synthetic resin material forming the frame 14 and integrated with the frame 14. Or the fiber reinforced resin which forms the outer layer part 72 of the holding | maintenance part 18 of the flame | frame 14 with the fiber reinforced resin which forms the inner layer part 70 is arrange | positioned in a metal mold | die, and a guide ring 12 and an inner layer pass through a pressurization and a heating process. The portion 70 and the outer layer portion 72 of the frame 14 can be integrally formed at the same time when the frame 14 is molded. Furthermore, after forming the inner layer part 70 in the recessed part 68 of the guide ring 12, it can also adhere to the holding hole 16 formed in the holding part 18 of the flame | frame 14 formed separately.

  The reinforcing fiber forming the inner layer portion 70 is, for example, carbon fiber, glass fiber or aramid fiber, and the impregnating synthetic resin is, for example, thermosetting resin such as epoxy resin or unsaturated polyester, or thermoplastic resin such as polyamide or PPS. preferable. When filling the recess 68, the sheet can be wound in the form of a sheet, a tape, a fiber bundle in which reinforcing fibers are aligned in one direction, or a combination thereof. The fiber reinforced resin that forms the inner layer portion 70 and the fiber reinforced resin that forms the outer layer portion 72 may be the same, or may be those in which the reinforced fibers or the resin to be impregnated are changed. In the case of forming with the same material, the reinforcing fiber can be easily exposed by making the amount of impregnation of the synthetic resin forming the inner layer portion 70 smaller than that of the outer layer portion 72.

  When the guide ring 12 and the frame 14 are integrally formed at the same time, the inner layer portion 70 and the outer layer portion 72 form a part of the holding portion 18, and after forming the frame 14, the frame 14 is formed in the final step. A part of the guide ring 12 is formed when it is fixed in the holding hole 16 by an appropriate means such as adhesion or welding. The inner layer portion 70 is preferably formed so as not to protrude outward in the radial direction from the large-diameter portions 12b1 on both sides in order to securely engage and hold the large-diameter portion 12b1 and the holding portion 18.

  FIG. 12 illustrates a part of the process when the guide ring 12 and the frame 14 are integrally formed at the same time using a mold to form the above-described fishing line guides 10B, 10C, and 10D.

  The illustrated mold includes an upper mold 74 and a lower mold 76 formed of an appropriate material such as a metal material, a casting, or a ceramic, and a cavity 78 that accommodates the guide ring 12 and the frame 14 is formed therebetween. To do.

Is provided. A plurality of such cavities 78 are preferably formed.

  When the guide ring 12 and the frame 14 are integrally formed using this mold, the upper mold 74 and the lower mold 76 are separated, and the entire one cavity 78 is opened to the outside.

  The guide ring 12 and the fiber reinforced resin are disposed in the cavity 78. At this time, the guide ring 12 is arranged at a predetermined position in the holding portion forming position 80, and the yarn body forming the fiber bundle is arranged along the outer peripheral portion of the guide ring 12 and the groove direction of the cavity 78, and this cavity 78. Place in the required shape or pattern inside. In the case where the yarn body is arranged without being impregnated with synthetic resin, after a predetermined pattern is formed, the closed cavity 78 is filled with synthetic resin, for example, by press-fitting. In the case where the synthetic resin is impregnated, it is not necessary to fill the synthetic resin.

  Thereafter, the upper die 74 and the lower die 76 are superposed and pressurized, and heated to the molding temperature of the material in the cavity 78. After the molding, the guide ring 12 and the frame 14 are released from the mold, the frames 14 connected to each other through a portion protruding from the cavity 78 are separated from each other, and end processing of each frame 14 is performed. Further, burrs are removed from each frame 14 as necessary.

  Then, after finishing the surface polishing process such as barrel polishing, surface processing such as painting of a required portion is performed, thereby completing a fishing line guide in which the ring guide 12 and the frame 14 are integrally formed at the same time.

  The guide ring 12 in each of the above-described embodiments is formed of a hard material that has higher wear resistance than the material of the frame 14, but the holding portion 18 of the frame 14 is a part of the guide ring or the guide ring. It can also be formed as a part. In this case, a fiber reinforced resin material is placed in the mold, and a smooth fishing line guide surface is formed at the stage of pressurization and thermoforming, or after the frame 14 is molded, the holding portion 18 is polished. Thus, a fishing line guide surface can be formed. Furthermore, the fishing line guide surface formed by a part of the frame 14 may be coated with a wear-resistant ceramic material, metal material, synthetic resin material, etc., and the coating surface is smoothed as necessary. It may be polished.
