Description

Technical Field

[0001] The present invention relates to a handle member for a fishing rod including a reel seat body and a grip, and a fishing rod provided with these components.

Background Art

[0002] Conventionally, various fishing rods provided with a reel seat for a fishing rod and a grip for a fishing rod are known.

[0003] In such a fishing rod, usually, a reel seat for a fishing rod and a grip for a fishing rod are placed on the rod body, and a reel leg placement portion for placing a reel leg on the upper side or the lower side of the main body is formed on the reel seat for a fishing rod.

[0004] As such a fishing rod, for example, Patent Document 1 discloses a fishing rod including a rod body, a cylindrical reinforcing resin layer provided on the circumferential surface of the rod body and having an uneven surface formed on the outer circumference, and a reel seat injection-molded on the outer circumferential surface of the reinforcing resin layer.

[0005] Further, Patent Document 2 discloses a fishing rod provided with a rear grip portion on the rear side of a reel seat including a cylindrical reel seat body having a reel leg placement portion on which the legs of a reel are placed, the fishing rod including a rod main body and a rear grip rod body in which the rear grip portion is integrally formed by increasing the diameter of the rear portion at a rate of diameter change larger than the rate of diameter change of the rod main body when forming a hollow rod body from a prepreg, the rear portion of the rod main body and the front portion of the rear grip rod body being overlapped and joined integrally inside and outside so as to form an overlapping portion of a predetermined length, and at least a part of the overlapping portion being located inside the reel seat body.

Patent Document 1

Patent Document 2

[0007] However, in the fishing rod disclosed in Patent Document 1, a solid reel seat is injection-molded onto the outer surface of a cylindrical reinforcing resin layer attached to the rod body. This increases the weight, and because the reel seat is thick, it functions as a cushioning material, which significantly reduces the sensitivity of the fishing rod.

[0008] Furthermore, in the fishing rod disclosed in Patent Document 2, the rear grip rod body and reel seat body are joined to the rod body, which inevitably increases the weight due to the bonding process. In addition, the presence of bonding parts and multiple layers acts as a buffer, resulting in a significant decrease in the sensitivity of the fishing rod.

[0009] The present invention has been made in view of the above circumstances, and its object is to provide a fishing rod handle member comprising a fishing rod reel seat and a fishing rod grip that is lightweight, does not easily dampen vibrations from the rod body, and can maintain strength without reinforcing the end of the grip with a separate member, and a fishing rod equipped therewith. Other objects of the present invention will become clear by referring to the entirety of this specification. [Means for solving the problem]

[0010] A fishing rod handle member according to one embodiment of the present invention comprises a reel seat body having a reel leg mounting portion on which a reel leg is mounted, and a grip connected to the reel seat body, which are integrally molded. The grip has one end connected to the reel seat body and the other end has a closed structure.

[0011] In a fishing rod handle member according to one embodiment of the present invention, the closing structure is a wall member that covers the other end of the grip.

[0012] In a fishing rod handle member according to one embodiment of the present invention, the wall member is formed perpendicular or inclined with respect to the extension direction of the grip.

[0013] In a fishing rod handle member according to one embodiment of the present invention, the reel seat body and the grip are made of carbon fiber reinforced plastic. Furthermore, in a fishing rod handle member according to one embodiment of the present invention, the carbon fibers of the carbon fiber reinforced plastic are formed continuously along the longitudinal direction of the fishing rod handle portion and along the closing structure.

[0014] In a fishing rod handle member according to one embodiment of the present invention, the end of the fishing rod body is attached to one end of the reel seat body, the end opposite to the grip. Furthermore, in a fishing rod handle member according to one embodiment of the present invention, one end of the reel seat body is formed to be hollow in order to attach the end of the fishing rod body.

[0015] In a fishing rod handle member according to one embodiment of the present invention, the reel seat body and the grip are formed such that the portion of the reel seat body other than one end and the grip other than the other end is hollow or solid.

[0016] In a fishing rod handle member according to one embodiment of the present invention, the reel seat body and the grip are formed solid in portions other than the other end of the grip, using a foamed material or a low-density resin.

[0017] A fishing rod according to one embodiment of the present invention is configured to include one of the above-described fishing rod handle members and a rod body. [Effects of the Invention]

[0018] According to the above embodiment, it is possible to provide a fishing rod handle member comprising a fishing rod reel seat and a fishing rod grip that are lightweight, less susceptible to damping of vibrations from the rod body, and can maintain strength without reinforcing the end of the grip with a separate member, and a fishing rod equipped with these.

Modes for Carrying Out the Invention

[0020] Hereinafter, embodiments of the fishing rod according to the present invention will be specifically described with reference to the accompanying drawings. The same reference numerals are given to common components in a plurality of drawings. Note that each drawing is not necessarily drawn to an exact scale for the sake of convenience of explanation.

[0021] Figure 1 shows one embodiment of a fishing rod according to the present invention. As shown in the figure, the fishing rod 1 according to one embodiment of the present invention comprises a rod body 2, a reel R attached to the rod body 2 via a reel seat 9, and a fishing line guide 10 attached to the rod body 2. In the illustrated embodiment, the reel seat 9 and the fishing line guide 10 each correspond to mounting parts attached to the outer circumferential surface of the rod body.

[0022] The rod body 2 is constructed by connecting, for example, a butt section 3, a middle section 5, and a tip section 7. Each of these rod sections is joined together, for example, in a parallel joint. The butt section 3, middle section 5, and tip section 7 can be joined together by a telescopic joint, a reverse parallel joint, a spigot joint, or any other known jointing method. The rod body 2 may also consist of a single rod section.

[0023] The butt section 3, the middle section 5, and the tip section 7 are, for example, made of a tubular body made of fiber-reinforced resin. This fiber-reinforced resin tubular body is made by winding a fiber-reinforced resin prepreg (prepreg sheet), which is made by impregnating reinforcing fibers with a matrix resin, around a core metal, and then heating and curing the prepreg sheet. As the reinforcing fibers contained in this prepreg sheet, for example, carbon fibers, glass fibers, and any other known reinforcing fibers can be used. As the matrix resin contained in the prepreg sheet, a thermosetting resin such as epoxy resin can be used. After the prepreg sheet has cured, the core metal is removed. The outer surface of the tubular body is also polished as appropriate. Each section of the rod may be constructed in a solid shape.

[0024] In the illustrated embodiment, the butt section 3, middle section 5, and tip section 7 are provided with a plurality of fishing line guides 10 (fishing line guides 10A to 10D) to guide the fishing line unwound from the reel 6 mounted on the reel seat 9. More specifically, the butt section 3 is provided with fishing line guide 10A, the middle section 5 is provided with fishing line guide 10B, and the tip section 7 is provided with fishing line guide 10C. A top guide 10D is provided at the tip of the tip section 7, but details are omitted.

[0025] Next, the reel seat body 12 and the reel seat 9 will be described with reference to Figure 2. The reel seat body 12 comprises a reel leg mounting surface 12a along its axial direction on which the reel leg 6b of the fishing reel 6 is placed. The reel seat body 12 is formed in a cylindrical shape as a whole. The reel seat body 12 can be configured to have a length of, for example, 60-160 mm, but is not limited to this.

[0026] Furthermore, the reel seat body 12 has a slightly bulging side opposite the reel leg mounting surface 12a, forming a grip portion 12b with a curved outer surface that makes it easier to grip by supporting the thenar eminence or its vicinity when held in the hand.

[0027] The reel leg mounting surface 12a of the reel seat body 12 can be formed to be flat or substantially flat with a greater curvature than other circumferential parts adjacent to the reel leg mounting surface 12a of the reel seat body 12 (e.g., the grip portion 12b), and is formed to extend in the axial direction of the reel seat body 12 as shown in Figure 2. A fixing hood 14 is integrally disposed at one end (the butt end side) of the reel seat body 12. One end of the reel leg mounting surface 12a of the reel seat body 12 is disposed inside the fixing hood 14.

[0028] A movable hood 22 is attached to the other end (rod tip side) of the reel seat body 12 so as to be movable in the axial direction. The reel seat body 12 and the movable hood 22 together are sometimes referred to as the reel seat 9, but further details are omitted.

[0029] Next, with reference to Figure 3 (and Figure 2), a fishing rod handle member 20 according to one embodiment of the present invention will be described. Here, the fishing rod handle member 20 includes the reel seat body 12 described above and the grip 4 formed adjacent to the reel seat body 12. Although the fishing rod handle member 20 may also include the reel seat 9 described above and the grip 4, in this embodiment it is defined as described above.

[0030] As shown in the figure, the fishing rod handle member 20 according to one embodiment of the present invention is configured such that a reel seat body 12 on which a reel leg mounting portion 12a on which a reel leg 6b is mounted is formed, and a grip 4 connected to the reel seat body 12 are integrally molded.

[0031] Next, with reference to Figures 4a, 4b, and 4c, a fishing rod handle member 20 according to one embodiment of the present invention will be described. Figure 4b shows a cross-sectional view of section AA in Figure 4a, and Figure 4c shows a cross-sectional view of section BB in Figure 4a. The fishing rod handle member 20 according to one embodiment of the present invention is integrally molded with a reel seat body 12 on which a reel leg mounting portion 12a on which a reel leg 6b is mounted is formed, and a grip 4 connected to the reel seat body 12. One end of the grip 4 is connected to the reel seat body 12, and the other end has a closed structure 21 (see Figures 4a and 4c described later). In the fishing rod handle member 20 according to one embodiment of the present invention, the closed structure 21 is a wall member 23 that covers the other end of the grip 4. The wall member 23 can be formed perpendicular or substantially perpendicular to the extension direction of the grip, but is not limited to this (the same applies throughout this specification).

[0032] The wall member 23 constitutes a part of the grip 4, and the wall member 23 gives the other end of the grip 4 (the end of the grip 4 opposite to the side to which the reel seat body 12 is connected) a closed structure (a structure in which the other end is closed from the outside). This eliminates the need to attach a separate metal or resin part to the other end by adhesive or the like. In contrast, when the other end has a closed structure, there is no need to provide a separate part, and no adhesive is needed, so the grip can be molded integrally including the closed structure, which allows it to resist external forces acting on the grip more evenly, making it possible to make it thinner and lighter while maintaining strength. Furthermore, since there is no need to provide a separate part, it is possible to reduce the man-hours required for assembly work.

[0033] According to the fishing rod handle member 20 of one embodiment of the present invention, it is possible to provide a fishing rod handle member comprising a fishing rod reel seat and a fishing rod grip that is lightweight, does not easily dampen vibrations from the rod body, and can maintain strength without reinforcing the end of the grip with a separate member.

[0034] Next, with reference to Figures 4a, 4b, and 4c, a fishing rod handle member 20 according to one embodiment of the present invention will be further described. As shown in Figure 4a, in the fishing rod handle member 20 according to one embodiment of the present invention, the inside of the fishing rod handle member can be formed hollow, but the details will be described later. By forming it hollow, it is possible to significantly reduce the weight without affecting the sensitivity provided to the fishing rod.

[0035] In a fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12 and the grip 4 may be formed hollow except for one end of the reel seat body 12 (the end on the rod tip side) and the other end of the grip 4 (the end on the rod butt side). By forming parts that do not necessarily need to be solid hollow in this way, it is possible to significantly reduce the weight without affecting the sensitivity of the fishing rod. Furthermore, in a fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12 and the grip 4 may be formed hollow except for the other end of the grip 4 (the end on the rod butt side). In this way, one end of the reel seat body 12 (the end on the rod tip side) may be made open to allow insertion of the rod, and the other end of the grip 4 (the end on the rod butt side) may be made closed 21.

[0036] Furthermore, in the fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12 and the grip 4 may be formed solid except for one end of the reel seat body 12 (the end on the rod tip side). In this way, one end of the reel seat body 12 (the end on the rod tip side) is made open, allowing the rod body to be inserted, while forming a grip that is easy to hold without affecting the sensitivity to the fishing rod. Furthermore, in the fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12 and the grip 4 may be formed solid including the other end of the grip 4 (the end on the rod butt side). In this way, even when formed solid, it is possible to suppress the increase in weight by using a low specific gravity resin, without affecting the sensitivity to the fishing rod. When forming a solid, a foamed material or a low specific gravity resin can be used. Here, a low specific gravity resin refers to a resin with a specific gravity of 1.2 or less, and examples include epoxy material and PP (polypropylene) material, but is not limited to these (the same applies throughout this specification). Furthermore, the same material used to form the reel seat body and grip, as described later, may be used. If the same material is used to form the reel seat body and grip, the reel seat body, grip, and solid portion may be formed as a single unit.

[0037] Furthermore, in the fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12 and the grip 4 may be formed with a portion being solid and the other portion being hollow, except for one end of the reel seat body 12 (the end on the rod tip side). In this way, one end of the reel seat body 12 (the end on the rod tip side) is made open, allowing the rod body to be inserted, while forming a grip that is easy to hold without affecting the sensitivity to the fishing rod. Furthermore, in the fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12 and the grip 4 may be formed with a portion being solid and the other portion being hollow, except for the other end of the grip 4 (the end on the rod butt side). In this way, a grip that is easy to hold without affecting the sensitivity to the fishing rod can be formed. The solid portion can be made of a foamed material or a low-density resin. The same material used to form the reel seat body and grip described later may also be used. If the material of the solid portion is the same as the material used to form the reel seat body and the grip, the reel seat body, grip, and solid portion may be formed as a single unit.

[0038] Furthermore, in the fishing rod handle member 20 according to one embodiment of the present invention, one end of the reel seat body 12 (the end on the rod tip side) may be formed hollow in order to attach the end of the fishing rod body 2. Also, as shown in Figures 4a and 4b, in the fishing rod handle member 20 according to one embodiment of the present invention, the end 13 of the fishing rod body 3 is configured to be attached to one end 15 of the reel seat body 12, the end 15 opposite to the grip 4. By doing so, unlike many conventional methods, it is not necessary to pass the rod body through the entire or substantially entire fishing rod handle member 20, thus significantly reducing the weight.

[0039] In a fishing rod handle member 20 according to one embodiment of the present invention, the reel seat body 12 and the grip 4, including the closed structure 21 in which the wall member 23 is formed, are made of carbon fiber reinforced plastic (CFRP). Alternatively, the reel seat body 12 and the grip 4 of the fishing rod handle member 20, including the closed structure 21 in which the wall member 23 is formed, may be made of CFRTP (continuous fiber), CFRTP (discontinuous fiber), or a hybrid. By forming them with such materials, it is possible to ensure sufficient rigidity and strength while suppressing an increase in weight as a handle member 20 with a closed structure for use in a fishing rod. Furthermore, in a fishing rod handle member according to one embodiment of the present invention, the carbon fibers of the carbon fiber reinforced plastic are formed continuously from the longitudinal direction of the fishing rod handle portion to the longitudinal direction of the grip and to the closed structure. This makes it possible to reduce weight by ensuring bending rigidity and to sensitively transmit vibrations of the fishing rod caused by a fish bite to the hand. More specifically, all parts that the operator (user) touches are a continuous, integrated structure, allowing vibrations input to the fishing rod body to be efficiently transmitted to the end of the grip. Furthermore, while an open structure at the end of the grip would require reinforcement against crushing using, for example, aluminum or resin parts, a closed structure using carbon material not only reduces weight but also achieves high rigidity.

[0040] Next, with reference to Figure 5, a fishing rod handle member 20 according to one embodiment of the present invention will be described. As shown in the figure, the fishing rod handle member 20 according to one embodiment of the present invention is integrally molded with a reel seat body 12 on which a reel leg mounting portion 12a on which a reel leg 6b is mounted is formed, and a grip 4 connected to the reel seat body 12. One end of the grip 4 is connected to the reel seat body 12, and the other end is a closed structure 21 (a wall member 23 that covers the other end of the grip 4), and the wall member 23 may be formed inclined with respect to the extending direction of the grip. In this way, the rear end of the fishing rod can be easily held under the arm. It should be noted that the wall member 23 may be formed inclined with respect to the extending direction of the grip, and this is consistent throughout this specification.

[0041] Next, with reference to Figure 6, a fishing rod handle member 20 according to one embodiment of the present invention will be described. As shown in the figure, the fishing rod handle member 20 according to one embodiment of the present invention is integrally molded with a reel seat body 12 on which a reel leg mounting portion 12a on which a reel leg 6b is mounted is formed, and a grip 4 connected to the reel seat body 12. The grip 4 has one end connected to the reel seat body 12, and the other end is a closed structure 21 (a wall member 23 that covers the other end of the grip 4). The wall member 23 is formed inclined with respect to the extension direction of the grip, and has a thickened portion 24 at the end of the wall member 23. In this way, it is possible to prevent cracking of the wall member (fiber-reinforced resin material) when the fishing rod is placed on the ground or the like. Note that the thickened portion 24 is applicable not only to this embodiment but also to other embodiments in this specification.

[0042] Next, with reference to Figure 7, a grip according to one embodiment of the present invention will be described. The grip according to one embodiment of the present invention consists only of the grip 4 of the fishing rod handle member 20 according to one embodiment of the present invention (i.e., without the reel seat body 12), and is otherwise the same as the grip 4 described above. As shown in the figure, the grip 4 according to one embodiment of the present invention has the end 13 of the fishing rod body 3 connected to one end, and the other end has a closed structure 21 (a wall member 23 that covers the other end of the grip 4), and the wall member 23 is formed inclined with respect to the extension direction of the grip. In this way, the rear end of the fishing rod can be easily held under the arm.

[0043] In a grip 4 according to one embodiment of the present invention, the grip 4 may be formed hollow except for the other end (the butt end). In this way, one end of the grip 4 (the tip end) can be made open, allowing the rod to be inserted, and the other end of the grip 4 (the butt end) can be made closed. By making the part that does not necessarily need to be solid hollow, it is possible to significantly reduce the weight without affecting the sensitivity of the fishing rod.

[0044] Furthermore, in the grip 4 according to one embodiment of the present invention, the grip 4 may be formed solid except for one end (the end on the rod tip side). In this way, one end (the end on the rod tip side) of the grip 4 is made open, allowing the rod to be inserted, while making it possible to form a grip that is easy to hold without affecting the sensitivity to the fishing rod. If it is made solid, a foamed material or a low-density resin can be formed. Alternatively, the same material as the material used to form the grip may be used. If the same material as the material used to form the grip is used, the grip and the solid portion may be formed as a single unit.

[0045] Furthermore, in the grip 4 according to one embodiment of the present invention, the grip 4 may be formed with a portion of it being solid and the rest being hollow, except for one end (the end on the rod tip side) and the other end (the end on the rod butt side). In this way, one end (the end on the rod tip side) of the reel seat body 12 can be made open, allowing the rod to be inserted, while forming a grip that is easy to hold without affecting the sensitivity to the fishing rod. The solid portion can be made of a foamed material or a low-density resin. Alternatively, the same material as that used to form the grip may be used. If the material of the solid portion is the same as that used to form the grip, the grip and the solid portion may be formed as a single unit.

[0046] Next, with reference to Figure 8, another grip according to one embodiment of the present invention (in the case of a grip for a carp fishing rod) will be described. As shown in the figure, the carp fishing rod grip 40 according to one embodiment of the present invention has the end 13 of the fishing rod body 3 connected to one end, and the other end has a closed structure 21 (a wall member 23 that covers the other end of the grip 4), and the wall member 23 is formed in a curved shape. In this way, it is possible to ensure the crush rigidity and strength of the grip end without attaching any additional parts.

[0047] A fishing rod 1 according to one embodiment of the present invention is configured to include a fishing rod handle member 20 or grip 4 or grip 40, and a rod body 2. According to the fishing rod 1 according to one embodiment of the present invention, it is possible to provide a fishing rod equipped with a fishing rod handle member or grip that is lightweight, does not easily dampen vibrations from the rod body, and can maintain strength without reinforcing the end of the grip with a separate member. Here, the method of attaching the end 13 of the fishing rod body 3 to the fishing rod handle member 20 or grip 4 or 40 can be, for example, fitting (press-fitting), bonding, or fastening, and is not limited to these. The attachment methods mentioned here have the advantage of making it easier to attach and detach the rod body from the handle member or grip.

[0048] Next, with reference to Figure 9, a method for molding a fishing rod handle member 20 according to one embodiment of the present invention will be described. First, as shown in Figure 9a, the dimensions and shape of the core member are determined to match the shape and dimensions of the fishing rod handle member 20 (for example, offset about 0.5-1 mm inward from the fishing rod handle member 20), and a soluble core member is fabricated (formation of the core member). The method for fabricating the core member can be injection molding, casting, 3D printing, etc., but is not limited to these. The surface layer of the core member is covered with a non-soluble resin.

[0049] Next, as shown in Figure 9b, a prepreg is laminated around the core member to form a preform. Here, a dry carbon fiber substrate that is not impregnated with resin may be used as the material for lamination.

[0050] Then, as shown in Figure 9c, the preform is placed in a mold and heated and pressurized to perform press molding. Note that autoclave molding or RTM molding may also be used, but the method is not limited to any particular form.

[0051] Next, as shown in Figure 9d, the molded product undergoes secondary processing (dimension setting and deburring). More specifically, excess material such as the front and back of the molded product, as well as burrs generated during molding, are removed. After that, the molded product that has undergone secondary processing is placed in water or hot water to dissolve the core material inside the molded product. In this way, the fishing rod handle member 20 is formed.

[0052] Next, as shown in Figure 9e, the outer surface of the fishing rod handle member 20 is painted or printed as appropriate. Then, as shown in Figure 9f, parts for attaching a reel are attached. Finally, as shown in Figure 9g, the reel can be placed on and fixed to the fishing rod handle member 20. In this way, a fishing rod handle member 20 according to one embodiment of the present invention is formed, in which a reel seat body 12 having a gripping portion and a reel leg mounting portion 12a on which the reel leg 6b is placed is formed, and a grip 4 connected to the reel seat body 12 is integrally molded.

[0053] In this way, the fishing rod handle member 20 according to one embodiment of the present invention makes it possible to significantly improve gripping ability, achieve significant weight reduction by integrally molding the handle member, reduce damping of vibrations from the rod body due to integral molding, thereby improving the sensitivity of the fishing rod, and maintain strength without reinforcing the end of the grip with a separate member, thereby making it possible to form a fishing rod handle member 20 comprising a fishing rod reel seat 13 and a fishing rod grip 4.

[0054] Next, another molding method for the fishing rod handle member 20 according to one embodiment of the present invention will be described. First, the dimensions and shape of the core member are determined to match the shape and dimensions of the fishing rod handle member 20 (for example, offset about 0.5-1 mm inward from the fishing rod handle member 20) (core member design). Using PVA, the core member (two halves of the core member) is formed by a 3D printer according to the dimensions and shape of the core member. The two halves of the core member are bonded together to assemble the core member.

[0055] Next, a carbon fiber reinforced plastic (CFRP) preform is formed around the core member (RTM molding, AC molding, VaRTM molding, F / M molding, S / W molding, I / P molding, etc.). The preform is taped or bagged and cured (heat processing at 80°C or higher). After that, the core member is dissolved in water (hot water, running water). Finally, the molded product is trimmed, painted, etc., to form the fishing rod handle member 20.

[0056] The fishing rod handle member 20 according to one embodiment of the present invention formed in this manner has a structure that can maintain strength without reinforcing the end of the grip with a separate member, a significant reduction in weight can be achieved by integrally molding the handle member, and the damping of vibrations from the rod body can be reduced due to integral molding, making it possible to improve the sensitivity of the fishing rod.

[0057] Next, another molding method for the fishing rod handle member 20 according to one embodiment of the present invention will be described. First, the dimensions and shape of the core member are determined to match the shape and dimensions of the fishing rod handle member 20 (for example, offset about 0.5-1 mm inward from the fishing rod handle member 20) (core member design). A sand mold core member is formed using water-soluble sand to match the dimensions and shape of the core member.

[0058] Next, a preform is formed around the core member using carbon that has not been impregnated with resin. Specifically, cloth (woven fabric), NCF (non-crimped fabric), braid (braided cord), and UD tape can be used, but are not limited to these. In addition, carbon fibers need to be formed in the core member, and a binder is used to impart tackiness. Possible types of binders include epoxy, rosin, polyamide, polyphenylene sulfide, polyetherimide, polyethersulfone, polysulfone, polyphenylene ether, polyimide, polyamideimide, and phenoxy, but are not limited to these. Here, the above example describes the case in which carbon that has not been impregnated with resin is used, but it is also possible to directly layer a prepreg, in which resin has been pre-impregnated into carbon cloth, etc., around the core using a hand lay-up method, etc., and then mold (cur) it. The preform is set in a mold and resin is injected (RTM molding method). After that, the sand mold core member is removed in water. Finally, the molded product is deburred, polished, painted, etc., to form the fishing rod handle member 20.

[0059] In this RTM molding method, the process of pouring in low-viscosity resin has the advantage of minimizing resin depletion, voids, and other areas where the resin has not penetrated, even when forming complex shapes such as handles. Furthermore, by using materials with better formability than prepregs, complex shapes can be formed without placing excessive stress on the fibers. Moreover, since the exterior is formed by the mold and the interior is formed by the core material, it is possible to mold both the exterior and interior to the desired dimensions, resulting in molded products with good surface quality in both areas. As described above, the RTM molding method makes it possible to stabilize quality and avoid insufficient strength.

[0060] Next, another molding method for the fishing rod handle member 20 according to one embodiment of the present invention will be briefly described. First, a mold is prepared that is molded to match the shape and dimensions of the fishing rod handle member 20. A prepreg is placed in the mold as a preform and pressed against the outer mold inside the mold using air pressure (internal pressure molding) to form a molded product. After that, the molded product is deburred, polished, painted, etc., to form the fishing rod handle member 20. In this internal pressure molding method, the prepreg is pressed against the mold (outer mold) by internal pressure during molding, which allows for a better molding of the outer surface of the molded product. In addition, by using a prepreg, it is possible to produce a molded product with a relatively small amount of resin, thus enabling weight reduction of the product.

[0061] Furthermore, the molding method for the fishing rod handle member 20 according to the embodiment of the present invention described above is also applicable to the grip 4 or grip 40 according to the embodiment of the present invention described above, and achieves the technical effects described above.

[0062] The dimensions, materials, and arrangements of each component described herein are not limited to those explicitly described in the embodiments, and each component can be modified to have any dimensions, materials, and arrangements that fall within the scope of the present invention. Furthermore, components not explicitly described herein may be added to the described embodiments, and some of the components described in each embodiment may be omitted. [Explanation of symbols]
