Description

[0001] This application is a divisional application of Chinese invention patent application No. 201880057734.X (application date: March 5, 2020; invention title: fishing rod with rod body having mounting components). Technical Field

[0002] This invention relates to a fishing rod having a rod body with mounting components. Background Technology

[0003] Fishing rods with mounting components such as line guides and reel seats are known to exist. Previously, these mounting components were attached to the rod body using line or resin sheets.

[0004] For example, Japanese Patent Application Publication No. 2008-263841 (Patent Document 1) and Japanese Patent Application Publication No. 2004-194563 (Patent Document 2) disclose fishing rods having mounting parts that are installed on the rod body via a line.

[0005] For example, Japanese Utility Model Application Publication No. 60-156963 (Patent Document 3) and Japanese Utility Model Application Publication No. 2-26474 (Patent Document 4) disclose fishing rods having mounting parts that are attached to the rod body by means of a resin sheet. In these patent documents, a sheet made of fiber-reinforced resin is used as the resin sheet.

[0006] To improve decorative properties and weather resistance, the wires and resin sheets used to mount mounting components are sometimes coated with synthetic resin coatings. As described in Japanese Patent Application Publication No. 2003-116417, there is a problem that synthetic resin coatings are prone to cracking.

[0012] Patent Document 4: Japanese Utility Model Application Publication No. 2-026474

[0013] Patent Document 5: Japanese Patent Application Publication No. 2003-116417 Summary of the Invention

[0014] One objective of this invention is to suppress cracking in the coating layer of the wire or sheet material used for mounting the cover assembly to the rod body. Another objective is to suppress accidental peeling of the coating layer from the rod body and to suppress cracking of the coating layer caused by such peeling. Other objectives of this invention will become apparent from the full text of this specification.

[0015] Solution for solving the problem

[0016] A fishing rod according to one embodiment of the present invention comprises: a rod body; a mounting member having a mounting portion for mounting to the outer peripheral surface of the rod body; a first fixing layer formed by winding a first sheet around the mounting portion and the rod body; a second fixing layer formed by winding a second sheet of fiber-reinforced resin around the outside of the first sheet; and a resin coating layer formed on the outside of the second fixing layer. In this embodiment, the coating layer is formed of a resin having a tensile elongation of 40% or more and a yield strain of 7% or more as measured according to JIS K 7161:2014, with a thickness of 1.3 mm or less.

[0017] When using a fishing rod, significant bending of the rod body is possible. The mounting components typically cannot fully follow this bending, resulting in stress on the coating layer during bending. Furthermore, the coating layer itself has high hardness, meaning it also cannot fully follow the rod body's bending, causing stress on the coating layer itself during bending. These stresses contribute to cracking in the coating layer. Moreover, the inventors have discovered that these stresses cause the coating layer to peel off from the rod body, leading to moisture absorption and changes in the coating layer's properties at the peeled areas, which also contribute to cracking.

[0018] According to the above embodiments, the coating layer is formed from resin with tensile elongation and yield strain within a specified range, and has a thickness below a specified value. Therefore, not only can the coating layer withstand the stress generated by the mounting component and the coating layer itself, but it can also suppress the modification of the physical properties of the coating layer caused by peeling, thereby suppressing the formation of cracks in the coating layer. That is, the fishing rod of one embodiment of the present invention can suppress the formation of cracks in the coating layer through the above dual mechanisms and their synergistic effect.

[0019] In one embodiment of the present invention, the tensile modulus of the coating layer, as measured according to JIS K 7161:2014, is 13 MPa or more and 420 MPa or less.

[0020] According to the above embodiment, the tensile elastic modulus of the coating layer is 13 MPa or more and 420 MPa or less, so even if the coating layer is subjected to stress due to the deflection of the rod body, the generation of cracks in the coating layer can be suppressed.

[0021] In one embodiment of the present invention, the adhesive strength between the coating layer and the second fixing layer, measured according to JIS K 6849:1994, is 88 N / cm. 2 above.

[0022] According to the above embodiment, the adhesion strength between the coating layer and the second fixing layer is 88 N / cm. 2 Therefore, even if the coating layer is stressed due to the deflection of the rod body, it can be prevented from peeling off from the second fixing layer. Such peeling, i.e., the peeling of the coating layer from the second fixing layer, may cause cracks to form near the coating layer. Thus, cracking of the coating layer can be prevented by preventing the coating layer from peeling off from the second fixing layer.

[0023] In one embodiment of the present invention, the coating layer comprises a first resin-based fixing layer formed on the outside of the second fixing layer and a second resin-based fixing layer formed on the outside of the first fixing layer.

[0024] According to this embodiment, when the coating layer is set to a predetermined thickness, the thickness of each layer constituting the coating layer can be reduced compared to the case where the coating layer is composed of a single layer. Specifically, compared to the thickness of a single layer ("single layer") constituting a coating layer of predetermined thickness, the thickness of the first fixing layer and the thickness of the second fixing layer can be reduced. This reduces residual stress in the first fixing layer and the second fixing layer, thereby suppressing peeling of the coating layer. This also suppresses cracking of the coating layer.

[0025] In one embodiment of the present invention, the gap between the front end of the coating layer and the front end of the second fixing layer is 3.0 mm or less. In another embodiment of the present invention, the gap between the rear end of the coating layer and the rear end of the second fixing layer is 1.0 mm or less.

[0026] According to the research of the inventors, cracks are prone to occur in the forward protrusion extending from the front end of the second fixing layer and the rear protrusion extending from the rear end of the second fixing layer in the coating layer. According to the above embodiment, by setting the portion extending forward from the front end of the second fixing layer in the coating layer to 3.0 mm or less, and setting the portion extending rearward from the rear end of the second fixing layer in the coating layer to 1.0 mm or less, cracking in the aforementioned forward and rear protrusions can be suppressed.

[0027] The fishing rod according to one embodiment of the present invention further includes a primer layer disposed between the first sheet and the mounting portion. This prevents the mounting component from peeling off from the rod body.

[0028] Invention Effects

[0029] According to the above embodiments of the present invention, cracking of the coating layer can be suppressed. Attached Figure Description

[0035] Figure 6 This is a schematic cross-sectional view illustrating a fishing rod according to another embodiment of the invention, cut along a plane through its central axis. Detailed Implementation

[0036] Hereinafter, embodiments of the fishing rod of the present invention will be described in detail with reference to the accompanying drawings. Common structural elements in the various drawings are labeled with the same reference numerals in the respective drawings. It should be noted that the drawings are not necessarily drawn to scale for ease of explanation.

[0037] Figure 1 This figure illustrates one embodiment of the fishing rod of the present invention. As shown, the fishing rod 1 of one embodiment of the present invention includes a rod body 2, a fishing reel R mounted on the rod body 2 via a reel seat 9, and a fishing line guide 10 mounted on the rod body 2. In the illustrated embodiment, the reel seat 9 and the fishing line guide 10 respectively correspond to mounting components mounted on the outer peripheral surface of the rod body.

[0038] The rod body 2 is constructed, for example, by connecting the handle section 3, the middle section 5, and the tip section 7. These rod bodies are joined, for example, in a parallel connection. The handle section 3, the middle section 5, and the tip section 7 can be joined by a snap-on, inverted parallel, in-low, or other known connection methods. The rod body 2 can also be constructed from a single rod body.

[0039] The handle section 3, middle section 5, and tip section 7 are, for example, tubular bodies made of fiber-reinforced resin. These tubular bodies are prepared by winding a fiber-reinforced resin prepreg (prepreg sheet) impregnated with a matrix resin in reinforcing fibers around a core member and then heating and curing the prepreg sheet. The reinforcing fibers included in the prepreg sheet can be, for example, carbon fiber, glass fiber, or any other known reinforcing fiber. The matrix resin included in the prepreg sheet can be a thermosetting resin such as epoxy resin. After the prepreg sheet has cured, the core member is removed. Furthermore, the outer surface of the tubular body is appropriately ground. Each rod body can also be constructed as a solid shape.

[0040] In the illustrated embodiment, multiple line guides 10 (line guides 10A to 10D) are provided on the handle section 3, the middle section 5, and the rod tip section 7 to guide the fishing line released from the fishing reel R mounted on the reel seat 9. More specifically, the handle section 3 has a line guide 10A, the middle section 5 has a line guide 10B, and the rod tip section 7 has a line guide 10C. A tip guide 10D is provided at the front end of the rod tip section 7.

[0041] In the illustrated embodiment, the reel seat 9 is mounted on the outer peripheral surface of the handle section 3.

[0042] Reference Figure 2 and Figure 3 The structure for mounting the fishing line guide to the rod body is further described. In these figures, the fishing line guide 10B mounted on the middle section 5 is illustrated. Fishing line guides other than the fishing line guide 10B (e.g., fishing line guides 10A, 10C, and 10D) can also be mounted on the corresponding rod body in the same manner as the fishing line guide 10B.

[0043] Figure 2 It is an illustrative representation of what will be Figure 1 A sectional view of a fishing rod cut through a plane passing through its central axis. Figure 3 It is Figure 2 The enlarged cross-sectional view shows a portion of the fishing rod. As shown in these figures, the fishing line guide 10B has a foot 10a extending axially along the intermediate section 5 and is mounted to the outer peripheral surface of the intermediate section 5 by means of the foot 10a. A first fixing layer 20, a second fixing layer 30, and a coating layer 40 are provided on the outer side of the foot 10a of the fishing line guide 10B. The terms "outer side" and "inner side" in this specification refer to the radial "outer side" and "inner side" of the intermediate section 5, respectively, unless the context allows for a different interpretation. Thus, the fishing line guide 10B is mounted to the outer peripheral surface of the intermediate section 5 by means of the foot 10a via the first fixing layer 20, the second fixing layer 30, and the coating layer 40.

[0044] Figure 2 Taking the layered structure shown in the figure as an example, the fishing rod of the present invention, in addition to Figure 2 In addition to the structure shown, various layers can be provided. For example, a primer can be applied to the surface of the foot 10a. Epoxy resin, polyurethane resin, or other known primers can be used as this primer. The primer is disposed, for example, between the upper surface 10a1 of the foot 10a and the first fixing layer 20. This allows the first fixing layer 20 to be more securely installed to the foot 10a with the help of the primer. An anchoring layer for improving adhesion can also be provided between the first fixing layer 20 and the second fixing layer 30.

[0045] The first fixing layer 20 is provided to cover a portion of the outer peripheral surface of the foot 10a and the intermediate section 5. In one embodiment, the first fixing layer 20 is configured to cover the entire foot 10a axially in the intermediate section 5. In this case, the first fixing layer 20 covers from the front end to the rear end of the foot 10a. In this specification, unless the context otherwise requires, the rod tip side of the fishing rod 1 is referred to as "front," "forward," or "front side," and the rod butt side is referred to as "rear," "rear," or "rear side." "Front end" refers to the end furthest from the center of the mounting member where the rod body and the mounting component are fixed together by the first fixing layer and the second fixing layer, and "rear end" refers to the end closer to the center of the mounting component. For example, in the case of a so-called single-base type fishing line guide, "front end" refers to the front end of the foot of the fishing line guide, and in the case of a so-called double-base type fishing line guide, it refers to the two front ends of the two feet of the fishing line guide. "Rear end" refers to the end of the foot opposite to the "front end" described above. In other embodiments, the first fixing layer 20 is configured to cover a portion of the foot 10a in the axial direction of the intermediate section 5. As described later, the first fixing layer 20 is formed of a first sheet 20S.

[0046] The second fixing layer 30 is disposed outside the first fixing layer 20 such that it covers the first fixing layer 20. In one embodiment, the second fixing layer 30 is configured to cover the entire first fixing layer 20 in the axial direction of the intermediate section 5. In this case, the second fixing layer 30 covers from the front end to the rear end of the first fixing layer 20. As will be described later, the second fixing layer 30 is formed from the second sheet 30S.

[0047] The coating layer 40 is a resin-based coating film disposed on the outer side of the second fixing layer 30, covering the second fixing layer 30. Alternatively, the coating layer 40 may be disposed to cover the entire second fixing layer 30, as shown in the figure.

[0048] The coating layer 40 is formed from various resin materials, such as epoxy resin, polyurethane resin, acrylic resin, or UV-curable resin (e.g., urethane acrylate, acrylic resin acrylate, epoxy acrylate). The material of the coating layer 40 is not limited to those exemplified in this specification; various resins can be used as its material. The coating layer 40 can be transparent or colored.

[0049] The coating layer 40 can consist of a single layer or multiple layers stacked radially in the intermediate section 5.

[0050] In one embodiment of the present invention, the coating layer 40 is formed on the outer side of the second fixing layer 30 with a substantially constant thickness. The coating layer 40 is formed such that its thickness T1 is 1.3 mm or less. In the case of uneven thickness of the coating layer 40, the thickness of the thickest part of the coating layer 40 is 1.3 mm or less. Furthermore, in one embodiment of the present invention, the thickness of the coating layer 40 is preferably 0.1 mm or more, more preferably 0.3 mm or more, further preferably 0.5 mm or more, and most preferably 0.8 mm or more. By making the coating layer 40 a predetermined thickness or more, peeling can be further suppressed.

[0051] In one embodiment of the present invention, the coating layer 40 has a tensile elongation of 40% or more and a yield strain of 7% or more, as measured according to JIS K 7161:2014. By making the tensile elongation of the coating layer 40 40% or more, cracking of the coating layer 40 can be suppressed even if the intermediate section 5 flexes. Furthermore, by making the yield strain 7% or more, deformation of the coating layer 40 can be suppressed even if the intermediate section 5 flexes repeatedly. It should be noted that, in this specification, for the tensile elongation, when the length of the unstretched test piece is set as L0 and the length of the test piece that breaks after stretching is set as L2, the tensile elongation = (L2-L0) / L0 × 100%. Furthermore, for the yield strain, when the length of the unstretched test piece is set as L0 and the length of the test piece that reaches the yield point after stretching is set as L1, the yield strain = (L1-L0) / L0 × 100%.

[0052] In one embodiment of the present invention, the tensile modulus of elasticity of the coating layer 40, as measured according to JIS K 7161:2014, is 13 MPa or more and 420 MPa or less. By setting the tensile modulus of elasticity of the coating layer to 13 MPa or more, cracking of the coating layer 40 can be suppressed even if the intermediate section deflects.

[0053] In one embodiment of the present invention, the adhesive strength between the coating layer 40 and the second fixing layer 30, as measured according to JIS K 6849:1994, is 88 N / cm. 2The above is achieved by making the adhesion strength between the coating layer 40 and the second fixing layer 30 88 N / cm. 2 In this way, the coating layer 40 can be prevented from peeling off from the second fixing layer 30 due to the deflection of the intermediate section 5. This also helps to prevent cracking of the coating layer 40.

[0054] Next, further reference Figure 4 and Figure 5 Instructions on how to install the fishing line guide 10B onto the rod body 5. Figure 4 and Figure 5 This is a diagram schematically illustrating a part of the method of installing the fishing line guide 10B onto the rod body 5. Figure 4 The cross-section of the intermediate section 5 is schematically shown along a plane perpendicular to its central axis. Figure 5 This is a 3D view of rod body 5.

[0055] When installing the fishing line guide B10 onto the middle section 5, first prepare the rod body 5, the fishing line guide 10B, the first sheet 20S, and the second sheet 30S.

[0056] The rod body 5 is prepared by heating and curing a prepreg sheet wound on the core component, as described above.

[0057] The fishing line guide 10B can be any fixed guide. The fishing line guide 10B can be a single-base type structure as shown in the figure, or a double-base type structure.

[0058] The first sheet 20S is, for example, a prepreg sheet in which fibers made of synthetic resin are impregnated with a resin composition containing a thermosetting resin. The fibers made of synthetic resin are, for example, fibers made of one or more substances selected from the group consisting of polyolefins, polyamides, polyacrylonitrile, and polyesters. A thermosetting resin is a resin that cures irreversibly upon heating due to a chemical reaction. Thermosetting resins that can be used as the resin composition include, for example, urea resin, melamine resin, phenolic resin, epoxy resin, unsaturated polyester resin, alkyd resin, and polyurethane resin. The thickness of the first sheet 20S is, for example, 20 μm to 300 μm. Suitable commercially available products can be used as the first sheet 20S.

[0059] When the total mass of the reinforcing fiber and the thermosetting resin in the first sheet 20S is set to 100wt%, the amount of thermosetting resin contained in the first sheet 20S is, for example, 50wt% or more or 60wt% or more.

[0060] The reinforcing fibers contained in the first sheet 20S can also be aligned in a direction forming a predetermined angle with the central axis X of the rod body 2. For example, the reinforcing fibers contained in the first sheet 20S can also be aligned at a 45° angle relative to the central axis X of the rod body 2. The reinforcing fibers contained in the first sheet 20S can also be woven into a plain weave.

[0061] In one embodiment of the present invention, the first sheet 20S has a tensile elongation of 15% or more, 18% or more, 19% or more, or 20% or more as measured according to JIS K 7161-1.

[0062] In one embodiment of the present invention, the tensile modulus of the first sheet 20S, as determined by JIS K 7161-1, is 980MPa to 3500MPa, 1100 to 3300MPa, 1500 to 3100MPa, or 2000 to 2800MPa.

[0063] In one embodiment of the present invention, the tensile breaking strength of the first sheet 20S, as determined by JIS K 7161:2014, is 20MPa~280MPa, 30MPa~260MPa, 40MPa~250MPa, or 58MPa~200MPa.

[0064] The second sheet 30S is, for example, a prepreg sheet in which reinforcing fibers are impregnated with a composition containing a thermosetting resin. The reinforcing fibers may include, for example, carbon fiber and glass fiber. The thermosetting resin contained in the composition impregnated in the second sheet 30S may include, for example, urea resin, melamine resin, phenolic resin, epoxy resin, unsaturated polyester resin, alkyd resin, and polyurethane resin.

[0065] In one embodiment of the present invention, the curing temperature of the thermosetting resin contained in the resin composition of the second sheet 30S is lower than that of the thermosetting resin contained in the resin composition of the first sheet 20S. For example, if the resin composition of the first sheet 20S contains a 120°C curing type epoxy resin as the thermosetting resin, an 80°C curing type epoxy resin can be used as the thermosetting resin of the second sheet 30S. The thickness of the second sheet 30S can also be, for example, 20 μm to 300 μm. Suitable commercially available products can be used as the second sheet 30S.

[0066] When the total mass of the reinforcing fiber and the thermosetting resin in the second sheet 30S is set to 100wt%, the amount of thermosetting resin contained in the second sheet 30S is set to, for example, 20wt% to 50wt% or 30wt% to 40wt%.

[0067] The fibers contained in the second sheet 30S can also be woven in a plain weave. The fibers contained in the second sheet 30S can also be oriented at 0° and 90° relative to the central axis X.

[0068] The resin composition contained in the first sheet 20S or the second sheet 30S is a composition containing a thermosetting resin as the main component. This resin composition may also contain known additives. When the resin composition contains both a thermosetting resin and additives, and the total mass of the resin composition is set to 100%, the mass percentage of the thermosetting resin is, for example, 50% or more, 60% or more, 70% or more, 80% or more, or 90% or more.

[0069] At least one of the first sheet 20S and the second sheet 30S may also be a resin sheet without reinforcing fibers. For example, the resin sheet may be a resin sheet based on a thermosetting resin.

[0070] To install the fishing line guide 10B onto the rod body 5, firstly, as... Figure 4 As shown, one end of the first sheet 20S is placed on the outer peripheral surface of the intermediate section 5, and the foot 10a of the fishing line guide 10B is placed on the first sheet 20S placed on the surface of the intermediate section. Next, the first sheet 20S is wound around the outer peripheral surface of the rod body 5 in approximately 1.3 layers. Thus, as shown, the foot 10a and the rod body 5 are covered by the first sheet 20S together. Alternatively, the foot 10a may be placed directly on the surface of the rod body 5, and then the first sheet 20S may be wound around the rod body 5 in a manner that surrounds the foot 10a and the outer peripheral surface of the rod body 5.

[0071] Next, a wound body is formed by winding a second sheet 30S around the outside of the first sheet 20S wound around the rod body 5. The second sheet 30S is wound around the rod body 5 in approximately 1.3 layers, covering the first sheet 20S.

[0072] The winding amount of the first sheet 20S and the second sheet 30S is not limited to what is explicitly stated in this specification. The first sheet 20S and the second sheet 30S can be wound with any number of layers. For example, the first sheet 20S and the second sheet 30S can also be wound more than two turns.

[0073] Next, the coiled body formed by the first sheet 20S and the second sheet 30S being wound around the rod body 5 is heated, thereby curing the thermosetting resin contained in the first sheet 20S to form a first fixing layer 20, and curing the thermosetting resin contained in the second sheet 30S to form a second fixing layer 30. The fishing line guide 10B is fixed to the rod body 5 through the first fixing layer 20 and the second fixing layer 30.

[0074] The heating of the aforementioned wound body can be performed using a known heating furnace. For example, the wound body can be heated to obtain the first fixing layer 20 and the second fixing layer 30 by placing it in a heating furnace maintained at a predetermined temperature for a predetermined time. The temperature of the heating furnace is, for example, 70–170°C, 80–160°C, 85–150°C, or 90–120°C, but it can also be heated at a temperature other than those mentioned above, depending on the curing temperature of the thermosetting resin. The heating time of the wound body in the heating furnace is, for example, set to 5 minutes to 3 hours, 15 minutes to 2.5 hours, or 30 minutes to 2 hours, but the heating time of the wound body can also be other than those mentioned above. When heating the wound body, a fastening tape can also be wound around the wound body to prevent the first sheet 20S and the second sheet 30S wound on the intermediate section 5 from moving during heating.

[0075] When the curing temperature of the thermosetting resin contained in the second sheet 30S is higher than that of the thermosetting resin contained in the first sheet 20S, the thermosetting resin of the outer second sheet 30S cures first, and then the thermosetting resin of the inner first sheet 20S, which has a higher curing temperature, cures.

[0076] After being heated for a specified time, the wound body is removed from the heating furnace and cooled at room temperature for a specified time. After the wound body has cooled sufficiently, a coating layer 40 is formed by covering the second fixing layer 30 formed on the wound body. Specifically, a resin composition such as epoxy resin, polyurethane resin, or acrylic resin is applied to cover the second fixing layer 30, and the applied resin composition is cured by heating, thereby forming the coating layer 40.

[0077] In one embodiment of the present invention, the tensile elongation of the first sheet 20S used to form the first fixing layer 20 is greater than the tensile elongation of the second sheet 30S used to form the second fixing layer 20. In this case, the tensile elongation of the first fixing layer 20 obtained by curing the first sheet 20S is greater than the tensile elongation of the second fixing layer 30 obtained by curing the second sheet 30S.

[0078] When replacing the fishing line guide 10B, which is fixed to the intermediate section 5 by the first fixing layer 20 and the second fixing layer 30, with a new fishing line guide, the fishing line guide 10B is first peeled off from the intermediate section 5. At this time, since the foot 10a is pulled in the direction of separation from the outer peripheral surface of the intermediate section 5, the first fixing layer 20 and the second fixing layer 30 are subjected to tensile stress. If the elongation at break of the first fixing layer 20 is greater than that of the second fixing layer 30, the first fixing layer 20 will not break even if tensile stress of the first fixing layer 20 and the second fixing layer 30 is applied to the first fixing layer 20 and the second fixing layer 30 to the extent that the second fixing layer 20 will break. Thus, the fishing line guide 10B can be peeled off with a force sufficient to break the second fixing layer 20. The second fixing layer 30 is located outside the first fixing layer 20, so as long as the first fixing layer 20 is not broken, the second fixing layer 30 can be removed together with the first fixing layer 20. If the second fixing layer 30 remains on the intermediate section 5, the efficiency of replacing the fishing line guide 10B will be reduced because the remaining portion of the second fixing layer 30 needs to be removed. By making the elongation rate of the first fixing layer 20 greater than that of the second fixing layer 30, it is possible to prevent the second fixing layer 30 from remaining on the intermediate section 5, thereby preventing a reduction in the efficiency of replacing the fishing line guide 10B.

[0079] If the tensile elongation of the first sheet 20S is 15%, it can prevent the first fixing layer 20 from breaking due to the tensile stress borne when replacing the fishing line guide 10B.

[0080] If the tensile modulus of the first sheet 20S is in the range of 980MPa to 3500MPa, the breakage of the first fixing layer 20 caused by the tensile stress borne when replacing the fishing line guide 10B can be prevented more reliably.

[0081] If the tensile breaking strength of the first sheet 20S is in the range of 20MPa to 280MPa, the breakage of the first fixing layer 20 caused by the tensile stress borne when replacing the fishing line guide 10B can be prevented more reliably.

[0082] In addition to the fishing line guide 10B, the fishing line guide 10 can also be installed on the corresponding rod body in the same way as described for the fishing line guide 10B. For example, the fishing line guide 10A is installed on the handle section 3 via the first fixing layer 20, the second fixing layer 30, and the coating layer 40.

[0083] In addition to the line guide 10, the reel seat 9 can also be installed on the corresponding rod body in the same way as described for the line guide 10B. For example, the reel seat 9 is installed on the handle section 3 via the first fixing layer 20, the second fixing layer 30, and the coating layer 40.

[0084] Next, refer to Figure 6 A fishing rod illustrating other embodiments of the present invention. Figure 6 The foot 10a of the fishing line guide 10B shown in the figure is... Figure 2 The embodiment shown differs in that it is covered by coating layer 140 instead of coating layer 40.

[0085] The coating layer 140 is formed of the same type of resin material as the coating layer 40. The coating layer 140 has a forward protrusion 140a that protrudes forward relative to the front end of the second fixing layer 30, and a rear protrusion 140b that protrudes rearward relative to the rear end of the second fixing layer 30.

[0086] The coating layer 140 is configured such that the distance T2 between its front end and the front end of the second fixing layer 30 is 1.0 mm or less. That is, the width T2 of the front protrusion 140a in the front-rear direction is 1.0 mm or less. Furthermore, the coating layer 140 is configured such that the distance T3 between its rear end and the rear end of the second fixing layer 30 is 3.0 mm or less. That is, the width T3 of the rear protrusion 140b in the front-rear direction is 3.0 mm or less.

[0087] In the coating layer 140, cracks are prone to occur in the portion extending forward from the front end of the second fixing layer 30 (i.e., the front protrusion 140a) and the portion extending rearward from the rear end of the second fixing layer 30 (i.e., the rear protrusion 140b). According to the above embodiment, by setting the width of the front protrusion 140a to 1.0 mm or less and the width of the rear protrusion 140b in the front-rear direction to 3.0 mm or less, cracks can be suppressed in the front protrusion 140a and the rear protrusion 140b.

[0088] Example

[0089] A test was conducted to investigate the durability of fishing rods with mounting components installed on the rod body. First, as a preliminary test, test pieces made of the same resin used to form the coating layer were prepared according to JIS K 7161:2014, and the tensile elongation and yield strain of the test pieces were measured (Preparation Examples 1-2 and Comparative Preparation Example 1). The results are shown in Table 1 below.

[0090] [Table 1]

[0091]

[0092] Next, the same resin used in Preparation Examples 1-2 and Comparative Preparation Example 1 was used as the coating material, and the fishing line guide (mounting component) was installed on the rod body. The results of the durability test on the obtained fishing rods are shown in Table 2 below (Examples 1-2 and Comparative Examples 1-2). In the durability test, the fishing line guide was oriented horizontally, and a 7kg fishing line was guided at the fishing line guide, with repeated upward movements at 45°. The number of times the fishing line guide peeled off from the rod body is shown in Table 2. Examples 1 and 2, which did not experience peeling off from the rod body after repeating this action 600 times, were evaluated as "○".
