Description

[Technical field]

[0001] The present invention relates to fishing tackle. [Background technology]

[0002] Fishing line guides for guiding a fishing line are known. The fishing line guide comprises a frame that is attached to the outer periphery of the fishing rod, and a guide ring that is fixed to the frame and through which the fishing line is actually passed. The frame is integrally formed with a ring holder for holding the guide ring through which the fishing line passes, and a fixing part for mounting to the outer surface of the fishing rod. The frame is generally formed integrally by pressing a metal plate material such as stainless steel, titanium, etc. If the product is made of a metal material, it is heavy and has poor performance such as flexibility. When a large number of fishing line guides having the above structure are attached along the axial direction, the fishing rod becomes heavy overall, and the fishing rod, which is required to be lighter in weight, cannot exhibit the desired performance.

[0003] From this perspective, fishing line guides made of fiber reinforced plastic have been proposed. For example, a method for manufacturing a fishing line guide having a frame made of fiber-reinforced prepreg, which has a ring holding portion and a fixing portion to be attached to a fishing rod, comprising a primary processing step of setting a laminated material made of fiber-reinforced prepreg whose matrix resin is a thermoplastic resin in a mold, pressurizing and fixing it to form the outer shape of the frame having a planar portion, and a secondary processing step of setting the laminated material that has been subjected to the primary processing step in a mold separate from the mold, heating and pressurizing it at a temperature at which the matrix resin becomes plastic, thereby changing the shape of the fine parts of the frame to form a processed surface that intersects with the extension direction of the planar portion, and hardening it at room temperature, and a method for manufacturing a fishing line guide has been proposed, in which the frame is cut out from the laminated material before or after the secondary processing step.

[Diagram 2] FIG. 2 is a perspective view of the fishing line guide according to the present invention from the other side (rear side); [Diagram 3] A cross-sectional view of a fishing line guide according to the present invention. [Figure 4] A cross-sectional view of a fishing line guide according to the present invention. [Diagram 5] Perspective view of the lower half of the mold [Figure 6] Perspective view of the upper half of the mold in an inverted state DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] Embodiments of the present invention are described.

[0039] The first invention is a fishing tackle. The fishing tackle is, for example, a fishing line guide. The main body of the fishing line guide is made of a fiber-containing resin composition. The main body is provided with ribs. Fishing line guides proposed up to now have no ribs (rib structure). In contrast, the present invention is provided with ribs (rib structure). This improves mechanical strength. Moreover, because it has ribs (rib structure), the fishing line guide of the present invention is lighter than previous fishing line guides.

[0040] The main body preferably includes a generally ring-shaped portion through which a fishing line is passed, and a support portion for attaching the generally ring-shaped portion to a fishing rod. The support part preferably includes a base part (trunk part) located on the fishing rod side. The support part preferably includes a branch part (branch part: a tip of this branch part (branch part) is connected to the ring-shaped part) that branches off at a tip of the base part (trunk part). The substantially ring-shaped portion may be circular, elliptical, or polygonal, such as triangular or rectangular, as long as it is annular. The substantially ring-shaped portion may be partially interrupted (open annular (approximately C-shaped)), i.e., it does not necessarily have to be a closed shape. However, it is generally a closed annular shape. The support portion is, for example, approximately Y-shaped. The tip of a branch portion (a branch) of this approximately Y-shape is connected to the approximately ring-shaped portion. It is the approximately Y-shaped portion that supports the approximately ring-shaped portion. The approximately Y-shaped portion may also be in the following case. The tip side of the approximately Y-shaped portion is approximately V-shaped. That is, there are two pieces on the tip side, but this may be three or more pieces. The number of pieces is not limited, but in reality there will be two or three. This is because the more there are, the heavier it becomes. When a force from the fishing line acts on the ring-shaped portion, the force acts on the tip of the support portion (branch portion: branch portion) that supports the ring-shaped portion. Since there is not one but multiple support portions (branch portions: branches), that is, since the support portion (supporting tip portion) is approximately Y-shaped, the support portion is less likely to bend (twist). Although it is difficult to bend (twist), because the tip of the support part (branch part) is divided into, for example, two parts, the mechanical strength of each support part (branch part) is reduced. Therefore, in order to compensate for the reduction in mechanical strength, it was decided to form a rib on the branch part. The inner part of the branch part is thin-walled. The outer part of the branch part is thick-walled. The thick part is the rib. The reason why the rib structure was preferable as described above is as follows. The rib structure (i.e., a structure in which the rib is located at an outer position rather than an inner position) had a higher resistance to deformation pressure such as twisting than a rib structure in which the inner part of the branch part is thick-walled and the outer part is thin-walled. The rib structure may be configured in a portion other than the branch portion. For example, a rib is configured in the approximately ring-shaped portion at a position sandwiched between the branch portions. The outer ring portion of the approximately ring-shaped portion at a position sandwiched between the branch portions is thin-walled and the inner ring portion of the approximately ring-shaped portion is thick-walled. The thick portion is a rib. Since the inner portion of the branch portion is configured as a thin-walled rib structure, the outer ring portion is thin-walled. If the opposite is true, the structure becomes complicated.

[0041] The extending direction of the branched portion (branches) of the approximately Y-shaped portion is preferably a direction of a line approximately tangent to the approximately ring-shaped portion. The reason is as follows: When the connecting direction between the branched portion and the approximately ring-shaped portion is a direction of a line approximately tangent to the approximately ring-shaped portion, the branched portion can firmly receive the force applied to the approximately ring-shaped portion. The width of the branched portion (branches) of the approximately Y-shaped portion was preferably wider than the width of the approximately ring-shaped portion for the following reasons: When the width of the branched portion (branches) was made larger, the mechanical strength of the branched portion increased, and the branched portion was able to easily withstand the force applied to the approximately ring-shaped portion. The thickness of the ribs at the branched portions (branches) of the substantially Y-shaped portion is preferably substantially the same as the thickness of the substantially ring-shaped portion for the following reasons: By making them the same thickness, the structure is simplified. The width of the base (trunk: the part on the root side from which the branched parts (branches) are derived) of the approximately Y-shaped part preferably decreased almost monotonically from the tip (where the branched parts are connected) towards the base end (the bending position). The thickness of the base (trunk) of the approximately Y-shaped part preferably increased almost monotonically from the tip towards the bending position. The reason for this is as follows: by increasing the thickness even when the width became narrow, the mechanical strength of the base (trunk) could be ensured. In other words, the base was able to firmly withstand the force applied to the approximately ring-shaped part. The thickness of the base (trunk) of the approximately Y-shaped portion is preferably thinner from the position past the bent position toward the base end for the following reasons: In order to make it easier to fix the base to the fishing rod, the thickness is made thinner from the approximately midpoint between the bent position and the base end toward the base end. The fibers were present across the approximately ring-shaped portion and the approximately Y-shaped portion.

[0042] The structure of the fishing line guide may adopt the contents disclosed in Patent Document 1 (Japanese Patent No. 5460441) or Patent Document 2 (Japanese Patent No. 5514061) as appropriate. For example, the structure of the main body may adopt the contents disclosed in Patent Document 1 or Patent Document 2 as necessary. For example, a ring made of metal (e.g., Ti, Al, Mg, SUS, etc.) or ceramic may be provided on the approximately ring-shaped portion. The base (trunk) of the approximately Y-shaped portion may be structured to be easily attached to a fishing rod, for example, bent.

[0043] The fibers of the fiber-containing resin composition constituting the main body of the fishing line guide are reinforced fibers. Examples of the fibers include inorganic fibers. They may be organic fibers. They may be a combination of both. The fibers may satisfy the following requirements: (length of at least 1 / 4 of the circumference of the approximately ring-shaped portion)≦(length in the longitudinal direction of the fibers). Alternatively, (length of at least 1 / 2 of the length from the base end of the approximately Y-shaped portion to the end of one branch portion)≦(length in the longitudinal direction of the fibers). Preferably, (length from the base end of the approximately Y-shaped portion to a part of the circumference of the approximately ring-shaped portion)≦(length in the longitudinal direction of the fibers). Although it varies depending on the size of the main body, specific values ​​are, for example, 1 cm or more. It is preferably 2 cm or more. It is more preferably 3 cm or more. It is furthermore 6 cm or more. There is no particular restriction on the average fiber length of the continuous reinforcement fibers used in the present invention, but from the viewpoint of improving molding processability, it is preferably in the range of 0.05 to 20,000 m. It is more preferably 100 to 10,000 m. More preferably, it was 1000 to 7000 m. A fiber length of more than 3 cm (6 cm) and a fiber length of 3 cm (6 cm) or less may be used in combination. The fiber length in the present invention is the weight average fiber length, unless otherwise specified. The average fiber diameter of the fibers was preferably 3 μm or more. More preferably, it was 4 μm or more. Even more preferably, it was 5 μm or more. It was preferably 50 μm or less. More preferably, it was 20 μm or less. Even more preferably, it was 12 μm or less. The average fiber diameter is the diameter of a single yarn.

[0044] Examples of the inorganic fibers include, but are not limited to, carbon fibers, silicon carbide fibers, alumina fibers, boron fibers, glass fibers, and metal fibers. Not only one type of fiber but also a plurality of types of fibers may be used in combination. From the viewpoints of mechanical strength and light weight, carbon fibers are preferred. Examples of the carbon fiber include polyacrylonitrile (PAN)-based carbon fiber, petroleum / coal pitch-based carbon fiber, rayon-based carbon fiber, cellulose-based carbon fiber, lignin-based carbon fiber, phenol-based carbon fiber, and vapor-grown carbon fiber. One or more of these may be used as appropriate. The carbon fiber used preferably has a tensile modulus of 100 GPa to 1000 GPa. The form of the carbon fiber is not particularly limited. The form of the carbon fiber may be continuous or discontinuous. An example of the continuous fiber is one in which carbon fibers are arranged in one direction (unidirectional material). Examples of discontinuous fibers include a material in which carbon fibers are arranged in a resin so as to be oriented in a specific direction, and a material in which carbon fibers are arranged randomly in the in-plane direction. The carbon fiber may be in the form of a single thread, a fiber bundle, or a mixture of both. Carbon fibers are generally in the form of a fiber bundle in which several thousand to several tens of thousands of filaments are assembled. When carbon fiber bundles are used as the carbon fibers, if the carbon fiber bundles are used as they are, the entangled portions of the fiber bundles may become locally thick, making it difficult to obtain a carbon fiber reinforced resin product having a thin end face. Therefore, when carbon fiber bundles are used as the carbon fibers, it is preferable to widen or open the carbon fiber bundles before use. Examples of the metal fibers include Al fibers, Au fibers, Ag fibers, Fe fibers, and stainless steel fibers. Examples of organic fibers include aramid fibers, aromatic polyamide fibers, cellulose fibers, polyethylene fibers, and poly(paraphenylene benzobisoxazole) fibers (Zylon (manufactured by Toyobo Co., Ltd.)). The fibers may be treated with a treatment agent. Examples of the treatment agent include a bundling agent. Examples of the treatment agent include a surface treatment agent. For example, the treatment agent disclosed in Japanese Patent No. 4894982 may be used. It is advantageous if the treatment agent on the fiber surface reacts with the functional group (reactive group: polar group) of the resin. The treating agent is selected from the group consisting of epoxy resins, urethane resins, silane coupling agents, water-insoluble polyamide resins, and water-soluble polyamide resins. Preferably, the treating agent is selected from the group consisting of epoxy resins, urethane resins, water-insoluble polyamide resins, and water-soluble polyamide resins. One or more kinds may be used.

[0045] Various resins can be used as the resin of the fiber-containing resin composition constituting the main body of the fishing line guide. The main body is produced, for example, by additive manufacturing technology described later. Therefore, it is preferably a resin (matrix resin) that can be used in additive manufacturing technology. Examples of such resins include thermoplastic resins. Examples of such resins include thermosetting resins. Only one of them may be used. They may be used in combination. There may be one type of resin, or two or more types. The resin may be in the form of a film (or sheet). The resin may be in the form of a fiber (yarn or filament). When the resin is in the form of a fiber, in the present invention, it is a so-called mixed fiber yarn (see, for example, WO2016 / 167136A1). In the case of a mixed fiber yarn, the technology disclosed in WO2016 / 167136A1 can be adopted. The resin preferably has a functional group (reactive group: polar group). It is also possible to use a resin that does not have a functional group (reactive group: polar group). Thermoplastic resins may consist of only thermoplastic resins or may contain thermoplastic resins as the main component. Either case is acceptable in the present invention. In the present invention (this specification), the term "thermoplastic resin" includes both cases consisting of only thermoplastic resins and cases containing thermoplastic resins as the main component, unless otherwise specified. A thermoplastic resin as the main component means that the thermoplastic resin is 50% by mass or more. Preferably, it is 80% by mass or more. More preferably, it is 90% by mass or more. Thermosetting resins may consist of only thermosetting resins or may contain thermosetting resins as the main component. Either case is acceptable in the present invention. In the present invention (this specification), the term "thermosetting resin" includes both cases consisting of only thermosetting resins and cases containing thermosetting resins as the main component, unless otherwise specified. A thermosetting resin as the main component means that the thermosetting resin is 50% by mass or more. Preferably, it is 80% by mass or more. More preferably, it is 90% by mass or more. Examples of the thermosetting resin include epoxy resin, vinyl ester resin, unsaturated polyester resin, diallyl phthalate resin, phenol resin, maleimide resin, cyanate resin, benzoxazine resin, and dicyclopentadiene resin. Examples of thermoplastic resins include polyolefin resins, polystyrene resins, thermoplastic polyamide resins, polyester resins, polyacetal resins (polyoxymethylene resins), polycarbonate resins, (meth)acrylic resins, polyarylate resins, polyphenylene ether resins, polyimide resins, polyethernitrile resins, phenoxy resins, polyphenylene sulfide resins, polysulfone resins, polyketone resins, polyether ketone resins, thermoplastic urethane resins, fluorine-based resins, and thermoplastic polybenzimidazole resins. Examples of the polyolefin resin include polyethylene resin, polypropylene resin, polybutadiene resin, polymethylpentene resin, vinyl chloride resin, vinylidene chloride resin, vinyl acetate resin, and polyvinyl alcohol resin. Examples of the polystyrene resin include polystyrene resin, acrylonitrile-styrene resin (AS resin), and acrylonitrile-butadiene-styrene resin (ABS resin). Examples of the polyamide resin include polyamide 6 resin (nylon 6), polyamide 11 resin (nylon 11), polyamide 12 resin (nylon 12), polyamide 46 resin (nylon 46), polyamide 66 resin (nylon 66), and polyamide 610 resin (nylon 610). Nylon (hereinafter sometimes abbreviated as "PA"), which is one of the polyamide resins, includes PA6 (also called polycaproamide, polycaprolactam, poly-ε-caprolactam), PA26 (polyethylene adipamide), PA46 (polytetramethylene adipamide), PA66 (polyhexamethylene adipamide), PA69 (polyhexamethylene azepamide), PA610 (polyhexamethylene sebacamide), PA611 (polyhexamethylene undecamide), PA612 (polyhexamethylene dodecamide), PA11 (polyundecane amide), PA12 (polydodecanamide), PA1212 (polydodecamethylene dodecamide), PA6T (polyhexamethylene terephthalamide), P Examples include A6I (polyhexamethylene isophthalamide), PA912 (polynonamethylene dodecamide), PA1012 (polydecamethylene dodecamide), PA9T (polynonamethylene terephthalamide), PA9I (polynonamethylene isophthalamide), PA10T (polydecamethylene terephthalamide), PA10I (polydecamethylene isophthalamide), PA11T (polyundecamethylene terephthalamide), PA11I (polyundecamethylene isophthalamide), PA12T (polydodecamethylene terephthalamide), PA12I (polydodecamethylene isophthalamide), polyamide XD6 (polymetaxylylene adipamide), polyamide XD10 (polyxylylene sebacamide), and the like.

[0046] The content ratio (mixing ratio) of the resin and the fiber in the fiber-containing resin composition constituting the main body of the fishing line guide was preferably as follows from the viewpoints of lightness and mechanical strength. For example, when the amount of carbon fiber was large, the mechanical strength increased. However, the lightness was lost. Conversely, when the amount of carbon fiber was small, the mechanical strength was low. From such a viewpoint, the preferable ratio of the two was as follows. Preferably, it was 20 / 100≦(volume of the resin) / (volume of the fiber+volume of the resin). More preferably, it was 25 / 100≦(volume of the resin) / (volume of the fiber+volume of the resin). Even more preferably, it was 30 / 100≦(volume of the resin) / (volume of the fiber+volume of the resin). Even more preferably, it was 35 / 100≦(volume of the resin) / (volume of the fiber+volume of the resin). Preferably, it was (volume of the resin) / (volume of the fiber+volume of the resin)≦55 / 100. More preferably, (volume of the resin) / (volume of the fiber+volume of the resin)≦50 / 100. Still more preferably, (volume of the resin) / (volume of the fiber+volume of the resin)≦45 / 100. Still more preferably, (volume of the resin) / (volume of the fiber+volume of the resin)≦40 / 100.

[0047] A second invention is a method for manufacturing a fishing tackle. For example, the method is a method for manufacturing the fishing line guide. The method includes a molding step in which a resin composition having fibers (for example, including fibers) is shaped using a 3D printer. The method includes a heating and pressurizing step in which the shaped object obtained in the molding step is heated and pressurized.

[0048] Additive manufacturing technology (3D printer modeling technology) is known. This technology is explained as follows in the "2013 Patent Application Technology Trends Survey Report (Summary) 3D Printers": 3D printing (additive manufacturing technology) refers to the process of creating an object from a numerical representation of a three-dimensional shape by attaching material. In many cases, this is achieved by stacking layer on top of layer. The term 3D printer is used in contrast to the two-dimensional output on paper. In ASTM F2792-12a (Standard Terminology for Additive Manufacturing Technologies), the term additive manufacturing is used. It is difficult to manufacture fiber-reinforced plastic products with three-dimensional shapes (not sheet (flat) shapes) using additive manufacturing technology alone. In particular, when the amount of fiber is increased as much as possible (relatively decreasing the amount of resin) to improve mechanical strength, it is difficult to manufacture such products using additive manufacturing technology alone. Therefore, in manufacturing the fishing tackle, we decided to heat and pressurize the object created by additive manufacturing technology.

[0049] The modeling process (additive manufacturing process) is a process in which additive manufacturing technology is used. In the additive manufacturing process, for example, an additive manufacturing device equipped with a nozzle is used. In the process, resin (plastic) and fibers are used. In the process, resin (matrix resin) and fibers may be supplied (discharged) from separate nozzles. Each material may be supplied (discharged) simultaneously. They may be supplied (discharged) with a time difference. A fiber-reinforced plastic material (material in which fibers are dispersed in resin) may be supplied (discharged) from one nozzle. A fiber-reinforced plastic product of a desired shape is obtained by the process. In the additive manufacturing process, for example, additive manufacturing technology using fused deposition modeling may be used. In the additive manufacturing process, for example, additive manufacturing technology is used that does not include a coating / printing process of coating / printing uncoagulated coagulant on the top surface of the laminate or on the surface of a sheet to be laminated on the laminate based on laminate area data in a predetermined cross section of a three-dimensional model, and a bonding process of overlapping and bonding the sheet coated / printed with the uncoagulated coagulant and the laminate in a warm state, or does not include a bonding process of stacking sheets with a coagulant selectively coated on the surface and selectively bonding the sheets with the coagulant, and additive manufacturing technology is used that uses fibers and resin for molding. In the additive manufacturing process, additive manufacturing technology is used that does not include a process of stacking and bonding sheets coated with a coagulant, and additive manufacturing technology is used that uses fibers and resin for molding. There are cases where the fishing tackle (for example, the fishing line guide) is formed by one (one) additive manufacturing process. The product A may be a combination of parts A1, ..., parts Ak (k is an integer less than or equal to n), ..., parts An (n is an integer greater than or equal to 2). In such a case, the part A1 is formed by one (single) additive manufacturing technology process A1. Similarly, the part Ak is formed by one (single) additive manufacturing technology process Ak. The part An is formed by one (single) additive manufacturing technology process An. When the parts A1, ..., Ak, ..., An formed by the additive manufacturing technology processes A1, ..., Ak, ..., An are combined, the combination will have the same shape as the product A.That is, the additive manufacturing technology process may require only one (one time) or may require two or more (two or more times). Either may be adopted.

[0050] In the modeling process (additive manufacturing technology process), when the resin is a thermosetting resin, the temperature is preferably 0°C or higher from the viewpoint of modeling properties. More preferably, it is 10°C or higher. Even more preferably, it is 20°C or higher. Even more preferably, it is 30°C or higher. It is preferably 350°C or lower. Even more preferably, it is 150°C or lower. Even more preferably, it is 100°C or lower. When the resin is a thermoplastic resin, the temperature is preferably 30°C or higher from the viewpoint of modeling properties. Even more preferably, it is 50°C or higher. Even more preferably, it is 100°C or higher. There is no particular restriction on the upper limit value. However, in general, it is preferably 700°C or lower. More preferably, it is 500°C or lower. Even more preferably, it is 450°C or lower. Even more preferably, it is 400°C or lower.

[0051] The product obtained through the additive manufacturing technology process was approximately flat. It was not a three-dimensional shape (three-dimensional shape). For example, it was not a three-dimensional shape having a flat surface portion and an intersecting surface portion intersecting the flat surface portion. It was not easy to obtain a product with the three-dimensional shape (three-dimensional shape) using additive manufacturing technology alone. It was easy (relatively easy) to obtain an approximately flat product using additive manufacturing technology. Since the product obtained through the additive manufacturing technology process contains a lot of fibers, all of the fibers were not integrally (strongly: rigidly) bonded by the resin. In the product, the fibers are partially separated. The fibers are only loosely connected to each other. The separation means that the product (the product obtained through the additive manufacturing technology process) is not a fixed shape. For example, when a force that bends the product in an approximately bow shape is applied to the product, the fibers will be displaced. If all of the fibers are integrally (strongly) bonded by the resin, the fibers will not be displaced even if the force described above is applied to the product. Of course, it's a different story if a force so great that it destroys it is used.

[0052] The pressurizing step (heating and pressurizing step) is preferably a step in which the shaped object placed in a mold and heated is pressurized. The pressurizing step may be performed in multiple steps. For example, it may be performed in two stages, such as a first pressurizing step and a second pressurizing step. The first pressurizing step is performed at a relatively low pressure. The second pressurizing step (second pressurizing step) is performed at a pressure higher than that of the first pressurizing step (first pressurizing step). The change in the pressurizing force from low to high in the pressurizing step may be a step function or may be continuous. In other words, the pressurizing force may gradually increase. This type of pressurizing is also considered to be performed in multiple steps. The first pressurizing step is a step in which the product obtained through the additive manufacturing technology step is pressurized. By the first pressurizing step, most of the fibers are integrally bonded by the resin. In other words, the fibers are integrally bonded to a certain degree firmly by the resin. When the fibers are integrally bonded by the resin, the fibers are less likely to shift position even if a large force is applied to the product. Even if a large force is applied to the product that has undergone the first pressurizing process, the product is unlikely to deform. Of course, it is a different matter if a force large enough to destroy the product is applied. In contrast, if a large force is applied to the product obtained through the additive manufacturing technology process, there is a risk that the fiber may become displaced. The product obtained through the first pressurizing process has a curved portion. Therefore, the shape of the product is three-dimensional. In contrast, the product obtained through the additive manufacturing technology process is flat. Therefore, at this stage, the product does not have a curved portion (a surface that intersects with a plane). In the first pressurizing process, a two-dimensional product is molded into a three-dimensional product. If the force applied in the first pressurizing process is too large, the fibers in the product obtained through the additive manufacturing technology process are not firmly integrated with the resin, so the shape is likely to be distorted. Therefore, it was preferable not to apply too large a force. In other words, the force applied in the first pressurizing process is smaller than the force applied to form the final product shape. In the first pressurizing step, a plurality of products obtained through the additive manufacturing technology step may be stacked and pressed. Of course, in some cases, only one product may be stacked.The second pressurizing step is a step in which the product obtained through the first pressurizing step is pressurized under heat. The force applied in the second pressurizing step is greater than the force applied in the first pressurizing step. That is, the force applied in the second pressurizing step is a force applied to form the final product shape. The volume of the product obtained through the second pressurizing step is smaller than the volume of the product obtained by the first pressurizing step. The pressure in the first pressurizing step is smaller than the pressure in the second pressurizing step. For example, (pressure in the first pressurizing step) / (pressure in the second pressurizing step) was 0.8 or less. For example, 0.7 or less. For example, 0.6 or less. For example, 0.5 or less. For example, 0.4 or less. For example, 0.02 or more. For example, 0.05 or more. For example, 0.1 or more. The pressure in the first pressurizing step was 0.8 kPa or more. For example, 4 kPa or more. For example, 8.0×10. 5 kPa or less. For example, 4.0×10 5 The pressure in the second pressurizing step was 1 kPa or more. For example, 5 kPa or more. For example, 1.0×10 6 kPa or less. For example, 5.0×10 5 kPa or less. (Volume of the product obtained through the first pressurizing step) / (Volume of the product obtained through the second pressurizing step)≦2.5. For example, 2 or less. For example, 1.5 or less. For example, 1.05 or more. For example, 1.1 or more.

[0053] The pressurizing step is preferably carried out under heated conditions. The reason is that by raising the temperature higher than room temperature (room temperature: for example, 25°C), the resin (resin composition) becomes soft. As a result, the moldability by pressurization is improved. The heating temperature should satisfy the following conditions. For example, the temperature was equal to or higher than the melting temperature in the 1 / 2 method using a flow tester CFT-500D (manufactured by Shimadzu Corporation) in accordance with the manual attached to the device. Preferably, the temperature was {the melting temperature + 10°C} or higher. More preferably, the temperature was {the melting temperature + 20°C} or higher. Preferably, the temperature was {the melting temperature + 60°C} or lower. More preferably, the temperature was {the melting temperature + 50°C} or lower. More preferably, the temperature was {the melting temperature + 40°C} or lower. Even more preferably, the temperature was {the melting temperature + 30°C} or lower. When the resin is a thermoplastic resin, the temperature may be, for example, higher than the melting temperature. When the resin is a thermosetting resin, the temperature may be, for example, less than the curing temperature. The melting temperature is also called the softening point (softening temperature). The temperature was obtained by the following method. A constant load extrusion type capillary rheometer (flow characteristic evaluation device: Flow Tester CFT-500D (manufactured by Shimadzu Corporation)) was used, and the measurement was performed according to the manual attached to the device. In this device, a constant load is applied from the top of the measurement sample (the sample in this case is not a resin containing fiber, but a resin not containing fiber) by a piston. The measurement sample filled in the cylinder is heated and melted. The molten measurement sample is extruded from the die at the bottom of the cylinder. A flow curve showing the relationship between the piston descent amount and the temperature is obtained. The melting temperature in the 1 / 2 method described in the manual was calculated as follows. 1 / 2 of the difference between the piston descent amount Smax at the time when the outflow ends and the piston descent amount Smin at the time when the outflow starts is calculated (this is X. X=(Smax-Smin) / 2). The temperature on the flow curve at the time when the piston descent amount becomes X on the flow curve is the melting temperature in the 1 / 2 method. For example, when the resin was an epoxy resin (thermosetting resin), the melting temperature (softening temperature) determined by the above method was about 70°C. When the resin was a benzoxazine (thermosetting resin), the melting temperature (softening temperature) determined by the above method was about 80°C. When the resin was a cyanate resin (thermosetting resin), the melting temperature (softening temperature) determined by the above method was about 80°C. When the resin is a thermosetting resin, the heating temperature is preferably a temperature of (resin curing temperature -70°C) or more. More preferably, it is a temperature of (resin curing temperature -60°C) or more. Even more preferably, it is a temperature of (resin curing temperature -50°C) or more. Even more preferably, it is a temperature of (resin curing temperature -40°C) or more. Preferably, it is a temperature of (resin curing temperature +20°C) or less. Even more preferably, it is a temperature of (resin curing temperature +10°C) or less. And even more preferably, it is a temperature of (resin curing temperature or less). The curing temperature is the peak temperature in the DSC curve. The heat curing temperature of epoxy resin (thermosetting resin) is about 120 to 180°C. The heat curing temperature of benzoxazine resin (thermosetting resin) is about 120 to 200°C. The heat curing temperature of cyanate resin (thermosetting resin) is about 150 to 250°C. When the resin is a thermosetting resin, an after-cure may be performed.

[0054] A mold is used in the pressurizing process. The mold comprises mold half A and mold half B. In the mold half A and mold half B, a recess (groove) without corners on the concave surface is formed on the opposing surfaces of the mold half A and the mold half B. The molded object obtained in the additive manufacturing technology process is placed in the recess of the mold half A. The mold half B is placed on top and pressurized. When the mold half A and the mold half B are combined, the space (cavity) formed by the recesses of the mold halves A and B is the shape of the final product. The inner surface of the recess (groove) has no corners. Therefore, the product obtained by applying pressure between the mold half A and the mold half B has no corners because the inner surface of the recess (groove) has no corners. If the cavity is composed only of a groove formed on the upper surface of the mold half A (if the mold half B facing the recess (groove) of the mold half A has a convex portion formed thereon or is flat), the product obtained in this manner will have corners even if there are no corners in the groove.

[0055] The present invention will be described in detail below. The following examples are merely examples of the present invention. The present invention is not limited to the following examples. In other words, the present invention also includes modifications and applications that do not significantly impair the features of the present invention.

[0056] [Example 1] A thermosetting resin (benzoxazine resin: manufactured by Aica Kogyo Co., Ltd.) was used. Carbon fiber (manufactured by Mitsubishi Rayon Co., Ltd., Pyrofil-TR-50S-12000-AD, 8000 dtex, fiber count 12000 f, fiber length 6 m) was used. The blending ratio was 40 parts by volume of the resin and 60 parts by volume of the carbon fiber.

[0057] A 3D printer (Velleman K8200) was used. Additive manufacturing technology was performed (nozzle temperature: 135°C, stage temperature: 50°C). This resulted in a product X made of the composition. The product X obtained through the additive manufacturing technology process was approximately flat. It was not a three-dimensional shape (solid shape). Since the amount of resin in the product X was relatively small, not all of the fibers were integrally bonded by the resin. The fibers in the product X were partially separated.

[0058] The product X obtained through the additive manufacturing process was placed in a mold. 3 A pressure of 100 kPa was applied. The molded product Y after the pressurization was removed from the molding die and placed in a metal mold. The metal mold comprises a metal mold half A (see FIG. 5) and a metal mold half B (see FIG. 6). Grooves (recesses) 11 and 12 are formed on the surfaces of the mold halves A and B. The shape of the space (cavity) formed by the grooves (recesses) 11 and 12 when the mold half A and the mold half B are joined together is the shape of the final product Z. The concave surfaces of the grooves (recesses) 11 and 12 have no corners. The molded product Y removed from the molding die was first placed in the groove (recess) 11 of the mold half A. The mold half B was placed over the mold half A on which the molded product Y was placed. Half of the molded product Y was located in the groove 11 of the mold half A, and the remaining half of the molded product Y was located in the groove 12 of the mold half B. When heated to 180℃, it is 6.0×10 4 A pressure of 100 kPa was applied to the molded product Y.

[0059] The fishing line guide Z thus obtained is shown in FIGS. Fig. 1 is a perspective view of the fishing line guide Z. Fig. 2 is a perspective view of the fishing line guide Z from the opposite side to that of Fig. 1. Fig. 3 is a cross-sectional view of the fishing line guide Z in the state of Fig. 1, taken along a line connecting the apex of the approximately ring-shaped portion 1 of the fishing line guide Z to the base end portion 3f of the approximately Y-shaped portion 2. Fig. 4 is a cross-sectional view taken along a line perpendicular to the cross-sectional line of Fig. 3 that crosses the opening 6 of the fishing line guide Z. In each figure, 1 is a roughly ring-shaped portion through which the fishing line is passed (inner diameter of ring: approximately 20.5 mm, outer diameter of ring: approximately 23.7 mm, thickness: approximately 2.3 mm, width: approximately 1.6 mm).

[0060] 2 is an approximately Y-shaped portion. The tip side of the approximately Y-shaped portion 2 has a branch structure. That is, the approximately Y-shaped portion 2 has two branch portions (branches) 2a, 2b on the tip side. Tips 3a, 3b of the branch portions 2a, 2b are connected to the approximately ring-shaped portion 1. The extension direction of the branch portions 2a, 2b is the direction of a tangent to the approximately ring-shaped portion 1. Since the connection direction between the branch portions 2a, 2b and the approximately ring-shaped portion 1 is approximately the direction of a tangent to the approximately ring-shaped portion 1, the branch portions 2a, 2b can easily withstand the force applied to the approximately ring-shaped portion 1. The base (trunk) 2c of the approximately Y-shaped portion 2 is one trunk. The intersection position 3c of the branch portion (branch) 2a and the branch portion (branch) 2b is the tip of the base (trunk) 2c.

[0061] The substantially ring-shaped portion 1 and the substantially Y-shaped portion 2 are integrally formed. This can be understood from the fact that the product X is obtained by additive manufacturing technology. Some of the carbon fibers dispersed in the thermosetting resin are longer than {(the circumferential length of the substantially ring-shaped portion 1) + (the length of the substantially Y-shaped portion 2)}. Therefore, some of the carbon fibers will be present across the substantially ring-shaped portion 1 and the substantially Y-shaped portion 2.

[0062] The branched portions 2a and 2b are slightly bent (the opening angle is, for example, about 160 to 175° (for example, 170°)) near a midpoint 3d of the branched portions 2a and 2b (for example, about 2 / 3 of the total length from the tip portions 3a and 3b). The base portion 2c is bent at a midpoint 3e (the opening angle is, for example, about 125 to 145° (for example, 135°)). The length of the branched portions 2a and 2b is about 40 mm. The width of the branched portions 2a and 2b is larger than the width of the approximately ring-shaped portion 1 so that the approximately ring-shaped portion 1 can be firmly supported even when the thickness of the thick portions of the branched portions 2a and 2b and the thickness of the approximately ring-shaped portion 1 are made approximately the same. The width of the branched portions 2a and 2b is about 3.2 mm. The thickness of the thick portions of the branched portions 2a and 2b is about 2.3 mm. The thickness of the thin portions of the branched portions 2a and 2b is about 1 mm. The length of the base 2c is about 35 mm. The width of the base 2c at the tip 3c (intersection of the branch 2a and branch 2b) is about 7 mm. The width of the base (trunk) 2c at the bent position 3e is about 4.6 mm. The thickness of the base 2c at the tip 3c is about 2.5 mm. The thickness of the base 2c at the bent position 3e is about 2.7 mm. The thickness of the base 2c at the base end 3f is about 1 mm. The width of the base 2c decreases almost monotonically from the tip 3c to the base end 3f. The thickness of the base 2c increases monotonically from the tip 3c to the bent position 3e. The reason for increasing the thickness is to ensure the mechanical strength of the base 2c since the width of the base 2c is narrowed in sequence. The thickness becomes thinner from the bent position 3e to the base end 3f. However, the degree of decrease from the approximately midpoint between the bent position 3e and the base end 3f to the base end 3f increases rapidly. The thickness of the portion where base portion 2c is attached to the fishing rod (from approximately the midpoint between bent position 3e and base end portion 3f to base end portion 3f) is made thin to make it easier to fix to the fishing rod.

[0063] Reference numerals 4a and 4b denote thick portions (ribs) at the branched portions 2a and 2b. Reference numerals 5a and 5b denote thin portions at the branched portions 2a and 2b. The thick portions (ribs) 4a and 4b are located on the outside of the branched portions 2a and 2b. The thin portions 5a and 5b are located on the inside of the branched portions 2a and 2b (the opening 6 side formed by the branched portions 2a and 2b). The "thickness" of the thick portions means "thicker" than the "thickness" of the thin portions. The thickness of the thick portions (ribs) 4a and 4b is the thickness at the branched portions 2a and 2b (approximately 2.3 mm). The width of the thick portions (ribs) 4a and 4b is approximately 1 mm. The width of the thin portions 5a and 5b is approximately 2.2 mm.

[0064] A thin-walled portion is also formed in the approximately ring-shaped portion 1. A thin-walled portion 7a is formed in the approximately ring-shaped portion 1 at a position sandwiched between branch portions 2a and 2b. The width of thin-walled portion 7a is approximately 1 mm. The width of thick-walled portion 7b is approximately 0.6 mm. The thickness of thick-walled portion 7b is approximately 2.3 mm. The thickness of thin-walled portion 7a is approximately 1 mm.

[0065] [Comparative Example 1] In Example 1, no ribs were formed. The presence of the ribs made it possible to achieve weight reduction while maintaining the necessary rigidity. In other words, when comparing a fishing rod equipped with the fishing line guide of Example 1 and a fishing rod equipped with the fishing line guide of Comparative Example 1, the fishing rod equipped with the fishing line guide of Example 1 was significantly easier to use.
