Description

Technical Field

[0001] The present invention relates to a fishing rod, and particularly to the structure of the surface of the fishing rod. Background Art

[0002] There is a case where a cork tube is attached to a grip of a fishing rod. If a cork tube is attached to the grip, it is difficult for the hand to slip when holding the grip. In addition, a high-class feeling can be presented by means of the cork tube. However, the weight of the fishing rod increases by using the cork tube.

[0003] In response to this, the applicant has proposed a structure using cork pieces on the surface of the grip as described in Patent Document 1 below. That is, the cork pieces are fixed to the rod body by the matrix resin of the rod body penetrating into the cork pieces. However, since the matrix resin penetrates into the cork pieces, the color tone and texture of the cork are likely to be damaged.

[0007] Technical Problem to be Solved by the Invention

[0008] The technical problem of the present invention is to ensure the texture peculiar to cork while suppressing an increase in the weight of the fishing rod.

[0009] Means for Solving the Technical Problem

[0010] The fishing rod according to the first aspect of the present invention includes a rod body, a surface layer portion, and an adhesive layer. The rod body is made of a fiber-reinforced resin. The rod body has a first resin. The surface layer portion has a cork piece. The cork piece covers the rod body. The adhesive layer is provided between the rod body and the surface layer portion. The adhesive layer bonds the rod body and the surface layer portion. The adhesive layer has a second resin different from the first resin.

[0011] According to this structure, the rod body is covered with the cork piece. Therefore, the fishing rod can be easily lightened compared with a cork tube. Moreover, the cork piece is bonded to the rod body by the adhesive layer sandwiched between the rod body and the cork piece, and the adhesive layer has a second resin different from the first resin of the rod body. Therefore, the color tone and texture of the cork are maintained, and the feel of the cork can be realistically expressed on the surface of the fishing rod.

[0012] In the fishing rod according to the second technical solution that follows the first technical solution, the surface layer portion has a first laminated portion. In the first laminated portion, the two end portions in the circumferential direction of the rod body of the cork sheet are laminated with each other. According to this structure, since the end portions of the cork sheet are laminated with each other, it is possible to prevent the cork sheet from peeling off from the rod body, and the cork sheet can be firmly adhered to the rod body. In addition, at the end portion of the cork sheet, minute irregularities are likely to occur in the surface direction and the thickness direction. However, by providing the first laminated portion, even if irregularities occur at the end portion of the cork sheet, it is possible to prevent the exposure of the rod body and easily maintain a good appearance.

[0013] In the fishing rod according to the third technical solution that follows the first technical solution or the second technical solution, the surface layer portion has a filling portion. The filling portion fills the cork sheet. According to this structure, the bubble spaces of the cork cells appearing on the surface of the cork sheet are filled by the filling portion. Therefore, the surface of the cork sheet becomes flat and smooth, a good appearance state can be obtained, and the hand feel when touching or holding the surface layer portion by hand also improves. In addition, cracking of the cork sheet can be suppressed.

[0014] In the fishing rod according to the fourth technical solution that follows the third technical solution, the surface layer portion has a defective portion. The defective portion is a portion where the cork sheet is defective. The filling portion includes a first filling portion. The first filling portion fills the defective portion. According to this structure, since the defective portion of the cork sheet is filled by the first filling portion, the surface layer portion can be made smooth, and in addition, it is possible to prevent the rod body from being exposed through the defective portion. Thus, even for the cork sheet, it is possible to ensure the texture and appearance unique to cork. In addition, the hand feel when touching or holding the surface layer portion by hand also improves. Furthermore, cracking of the cork sheet starting from the defective portion is suppressed, and the durability can be improved.

[0015] In the fishing rod according to the fifth technical solution that follows the third technical solution or the fourth technical solution, the surface layer portion has a first laminated portion. In the first laminated portion, the two end portions in the circumferential direction of the rod body of the cork sheet are laminated with each other. The filling portion has a second filling portion. The second filling portion is provided in the first laminated portion. According to this structure, since the second filling portion is provided in the first laminated portion, the irregularities that are likely to occur at the end portion of the cork sheet are filled by the second filling portion. Therefore, the first laminated portion becomes smooth, and the first laminated portion is not likely to become prominent. Thus, a good appearance and a good hand feel are ensured. In addition, cracking of the cork sheet starting from the irregularities at the end portion can be suppressed, and the durability can be improved.

[0016] In the fishing rod of the sixth aspect that follows any one of the first to fifth aspects, the cork sheet includes an integrated sheet. The integrated sheet is composed of strip-shaped cork sheets arranged in the second direction. The strip-shaped cork sheets extend in the first direction. The second direction is orthogonal to the first direction. According to this structure, since the cork sheet is an integrated sheet, a sense of luxury can be obtained as compared with a cork sheet composed of an aggregate of granular cork formed by crushing cork. In addition, real cork can be represented, and the same appearance as that of a cylindrical cork body can be obtained, and it is possible to easily achieve both light weight and a sense of luxury.

[0017] In the fishing rod of the seventh aspect that follows the sixth aspect, the surface layer portion has a first direction portion. In the first direction portion, the first direction is along the circumferential direction of the rod body. According to this structure, in the first direction portion, the extending direction of the strip-shaped cork sheets is the circumferential direction of the rod body. Therefore, in fishing where a large force acts repeatedly along the axial direction of the rod body on the fishing rod, it is possible to prevent the cork from being damaged or perforated due to gripping the first direction portion. The situation where a large force acts repeatedly along the axial direction of the rod body on the fishing rod is, for example, fishing such as repeated casting.

[0018] In the fishing rod of the eighth aspect that follows any one of the first to seventh aspects, the rod body has a diameter-changing portion. In the diameter-changing portion, the outer diameter of the rod body expands or contracts along the axial direction of the rod body. The surface layer portion has a first covering portion. The first covering portion covers the diameter-changing portion. According to this structure, since the diameter-changing portion is covered with the cork sheet, it is also possible to easily provide cork on the surface of the diameter-changing portion. Moreover, by virtue of the anti-slip effect unique to cork, it is possible to easily ensure a large gripping force in the diameter-changing portion and firmly grip the diameter-changing portion.

[0019] In the fishing rod of the ninth aspect that follows any one of the first to eighth aspects, the rod body has a non-circular cross-sectional special-shaped cross-section portion. The surface layer portion has a second covering portion. The second covering portion covers the special-shaped cross-section portion. According to this structure, since the special-shaped cross-section portion is covered with the cork sheet, it is also possible to easily provide cork on the surface of the special-shaped changing portion. Moreover, by virtue of the anti-slip effect unique to cork, it is possible to easily ensure a large gripping force in the special-shaped changing portion and firmly grip the special-shaped changing portion.

[0020] Advantages of the Invention

[0021] As described above, since the rod body is covered with the cork sheet, it is possible to easily lighten the fishing rod while using cork. In addition, since the cork sheet is adhered to the rod body by means of the adhesive layer, it is possible to maintain the unique color tone and texture of cork. Brief Description of the Drawings

[0039] Hereinafter, with reference to Figures 1 to 10 A fishing rod according to an embodiment of the present invention will be described. In addition, the axial direction of the fishing rod is defined as the front - rear direction, the tip side of the rod is defined as the front side, and the butt side of the rod is defined as the rear side. Further, the circumferential direction of the fishing rod is simply referred to as the circumferential direction. The fishing rod of the present embodiment includes a reel seat 2 for mounting a reel (not shown). However, the fishing rod may also be a so - called long fishing rod that does not have a reel seat 2. In the present embodiment, the fishing rod includes a rod main body 1 and a reel seat 2.

[0040] <Reel seat 2>

[0041] The reel seat 2 is a cylindrical structure also called a tube seat. The reel seat 2 is attached to the outer side in the radial direction at a specified position of the rod main body 1 and is fixed so as not to move relative to the rod main body 1. The reel seat 2 of the present embodiment is for fixing a double - bearing reel (not shown). In the normal use state, the double - bearing reel is located on the upper side of the fishing rod. However, as will be described later, the reel seat 2 can also mount a spinning reel.

[0042] The reel seat 2 includes a cylindrical reel seat main body 3 that is non - movably mounted on the rod main body 1, a cylindrical movable cover 4 that is movably attached to the reel seat main body 3 and fixes the front end portion of the reel foot, and a fixing nut 5 that moves the movable cover 4 back and forth. In addition, in the reel seat main body 3, a fixing cover 6 that fixes the rear end portion of the reel foot and a trigger 7 for gripping a finger are integrally formed. The fixing cover 6 is formed on the upper surface of the reel seat main body 3, and the trigger 7 is formed on the lower surface of the reel seat main body 3. The movable cover 4 and the fixing nut 5 are located on the front side of the reel seat main body 3.

[0043] The reel seat main body 3 is composed of one part. The material of the reel seat main body 3 can be a synthetic resin, metal, etc., but particularly preferably a resin molded product formed by injection molding of a hard synthetic resin. The synthetic resin can be various resins, but preferably a fiber - reinforced resin, and particularly preferably a fiber - reinforced resin using short fibers with a length of 1 mm or less as reinforcing fibers. In addition, the fiber is preferably carbon fiber.

[0044] <Rod main body 1>

[0045] The rod main body 1 has reinforcing fibers and a first resin. Various fibers such as carbon fibers are used as the reinforcing fibers. The first resin is a matrix resin, for example, an epoxy resin. The rod main body 1 can be tubular (hollow) or solid. The tubular rod main body 1 is formed by winding a preformed plastic around a mandrel and heating and firing it. The preformed plastic has reinforcing fibers and a first resin.

[0046] The rod main body 1 includes a main rod body 10 and a grip rod body 11. The main rod body 10 can be hollow or solid, but in this embodiment, it is hollow. The reel seat 2 is attached to the main rod body 10. The main rod body 10 penetrates through the reel seat 2 from front to back. The main rod body 10 can be a single-piece structure or a multi-piece structure. The main rod body 10 extends forward from the reel seat 2 and also extends backward from the reel seat 2. The grip rod body 11 is attached to the radially outer side of the rearward extension portion of the main rod body 10, which is the portion extending backward from the reel seat 2. The grip rod body 11 is hollow. The grip rod body 11 is provided on the rear side of the reel seat 2. Specifically, it is located immediately after the reel seat 2 and is provided adjacent to the rear side of the reel seat 2. The grip rod body 11 extends from the reel seat 2 to the rear end portion of the fishing rod. A tail plug 8 is attached to the rear end portion of the grip rod body 11. The grip rod body 11 has a grip portion. In this embodiment, the grip rod body 11 has a first grip portion and a second grip portion. The first grip portion is located on the front side, and the second grip portion is positioned behind the first grip portion and is spaced apart from it.

[0047] The grip rod body 11 is composed of one fiber-reinforced resin component. The grip rod body 11 has a first large-diameter portion 21, a small-diameter portion 22, and a second large-diameter portion 23. The first large-diameter portion 21 constitutes the front portion of the grip rod body 11. The first large-diameter portion 21 is adjacent to the rear side of the reel seat 2. As Figure 3 (a) shows, the first large-diameter portion 21 is circular in cross-section. The main rod body 10 is inserted through the radially inner side of the first large-diameter portion 21. A ring-shaped space portion is formed between the first large-diameter portion 21 and the main rod body 10 in the radial direction. The first large-diameter portion 21 constitutes the first grip portion. The first large-diameter portion 21 is mainly held by the hand holding the reel. For example, when holding the reel with the right hand, the right hand holds the first large-diameter portion 21.

[0048] As Figure 3As shown in (b), the small-diameter portion 22 is circular in cross-section. The small-diameter portion 22 is smaller in diameter than the first large-diameter portion 21. The small-diameter portion 22 is located behind the first large-diameter portion 21 and in front of the second large-diameter portion 23. The small-diameter portion 22 is positioned between the first large-diameter portion 21 and the second large-diameter portion 23 in the front-rear direction. The small-diameter portion 22 forms the middle portion of the grip rod body 11. The main rod body 10 is fixed to the small-diameter portion 22. The outer peripheral surface of the main rod body 10 is in close contact with the inner peripheral surface of the small-diameter portion 22. The first large-diameter portion 21 and the small-diameter portion 22 are coaxial with each other. Between the first large-diameter portion 21 and the small-diameter portion 22 in the front-rear direction, a first diameter-changing portion 24 is provided. The first diameter-changing portion 24 connects the first large-diameter portion 21 and the small-diameter portion 22 in the front-rear direction. In the first diameter-changing portion 24, the outer diameter gradually decreases toward the rear side. That is, the first diameter-changing portion 24 is a diameter-reducing portion that reduces in diameter toward the rear side.

[0049] The second large-diameter portion 23 is located behind the small-diameter portion 22. The second large-diameter portion 23 forms the rear portion of the grip rod body 11. The second large-diameter portion 23 is larger in diameter than the small-diameter portion 22. As Figure 3 shown in (c), the second large-diameter portion 23 is non-circular in cross-section. The second large-diameter portion 23 is a special cross-sectional portion with a non-circular cross-section. The cross-sectional shape of the second large-diameter portion 23 can be various shapes, for example, it is a polygon in cross-section, and as an example, it is an inverted trapezoid, an inverted triangle shape, etc. in cross-section. The second large-diameter portion 23 forms the second grip portion. The second large-diameter portion 23 is held by the hand on the side opposite to the hand holding the fishing reel during double casting. For example, during double casting, when the fishing reel is held with the right hand, the second large-diameter portion 23 is held with the left hand.

[0050] Between the small-diameter portion 22 and the second large-diameter portion 23 in the front-rear direction, a second diameter-changing portion 25 is provided. In the second diameter-changing portion 25, the outer diameter gradually increases toward the rear side. That is, the second diameter-changing portion 25 is a diameter-expanding portion that expands in diameter toward the rear side. In addition, the cross-sectional shape of the second diameter-changing portion 25 gradually changes from circular to non-circular toward the rear side. Therefore, the second diameter-changing portion 25 is also a cross-sectional shape-changing portion whose cross-sectional shape gradually changes toward the rear side. In the present embodiment, from the small-diameter portion 22 to the second large-diameter portion 23, while expanding in diameter, the cross-sectional shape gradually changes from circular to an inverted trapezoid.

[0051] <Surface layer portion 30>

[0052] The fishing rod has a surface layer portion 30 that covers the rod main body 1. The surface layer portion 30 forms the outermost layer. The surface layer portion 30 has a cork sheet 31. The cork sheet 31 will be described later. In the present embodiment, the surface layer portion 30 is provided on the grip rod body 11. The surface layer portion 30 is provided over the entire length of the grip rod body 11 and over the entire circumference of the grip rod body 11. The surface layer portion 30 covers the entire length and the entire circumference of the grip rod body 11. The surface layer portion 30 has a first covering portion 41 that covers the first diameter change portion 24, a second covering portion 42 that covers the second major diameter portion 23, a third covering portion 43 that covers the first major diameter portion 21, a fourth covering portion 44 that covers the small diameter portion 22, and a fifth covering portion 45 that covers the second diameter change portion 25.

[0053] <Adhesive layer 32>

[0054] As shown in Figure 3 (a) as an enlarged view, the fishing rod has an adhesive layer 32 that bonds the rod main body 1 and the surface layer portion 30. In the present embodiment, the surface layer portion 30 is provided on the radially outer side of the grip rod body 11. Therefore, the adhesive layer 32 is provided between the grip rod body 11 and the surface layer portion 30. The adhesive layer 32 is provided on the entire outer peripheral surface of the grip rod body 11, but may also be provided only on a part of the outer peripheral surface of the grip rod body 11. The thickness of the adhesive layer 32 is thinner than the thickness of the grip rod body 11 and thinner than the thickness of the surface layer portion 30. The adhesive layer 32 is composed of various adhesives and contains a second resin different from the above-mentioned first resin. The adhesive may be a pressure-sensitive adhesive or a heat-sensitive adhesive.

[0055] <Cork sheet 31>

[0056] A cork sheet 31 is pasted on the outer peripheral surface of the grip rod body 11. The cork sheet 31 is bonded to the outer peripheral surface of the grip rod body 11. As Figure 1 shown, in the present embodiment, the cork sheet 31 is pasted over the entire length and the entire circumference of the grip rod body 11, covering the grip rod body 11 over the entire length and the entire circumference.

[0057] The cork sheet 31 is an integrated sheet. The thickness of the integrated sheet is preferably 0.1 mm to 1 mm. The thickness of the integrated sheet is preferably not more than the thickness of the grip rod body 11. The details of the integrated sheet are shown in Figure 4 , and in addition, in Figure 5 it is shown with the wood grain 33 of the cork omitted. The defect portion 34 described later crosses the wood grain 33. The integrated sheet is composed of a plurality of strip-shaped cork sheets 35. One strip-shaped cork sheet 35 is drawn out and shown in Figure 4 . The strip-shaped cork sheet 35 extends along the first direction X. The first direction X is the extending direction of the strip-shaped cork sheet 35 and is the length direction of the strip-shaped cork sheet 35. The wood grain 33 of the cork extends in the first direction X. Figure 6 (b).

[0058] A plurality of strip-shaped cork pieces 35 are arranged in a second direction Y orthogonal to the first direction X. The second direction Y is the arrangement setting direction of the strip-shaped cork pieces 35 and is the short side direction (width direction) of the strip-shaped cork pieces 35. Adjacent strip-shaped cork pieces 35 are joined to each other by a first joining line 36. The first joining line 36 extends along the first direction X. In other words, the plurality of strip-shaped cork pieces 35 are joined in the second direction Y. The width of the strip-shaped cork piece 35 (the dimension in the second direction Y) is constant along the first direction X. In addition, the widths of most of the strip-shaped cork pieces 35 may be the same as or different from each other. In the present embodiment, the widths of most of the strip-shaped cork pieces 35 are different from each other and are random.

[0059] The strip-shaped cork piece 35 is composed of a plurality of thin pieces 37 joined in the first direction X. The thin piece 37 has a structure in which a smaller cork board is sliced thinly. The thin pieces 37 are arranged in the first direction X. The thin piece 37 has a shape that is long in the first direction X, specifically, a rectangle that is long in the first direction X. The lengths of the plurality of thin pieces 37 of one strip-shaped cork piece 35 in the first direction X may be the same as or different from each other. In the present embodiment, they are different from each other and have random lengths. In Figure 6 (a) shows one thin piece 37. Adjacent thin pieces 37 are joined to each other by a second joining line 38. The second joining line 38 extends along the second direction Y. That is, the short sides of adjacent thin pieces 37 in the first direction X are joined to each other by the second joining line 38. In this way, the integrated piece is an aggregate of many thin pieces 37.

[0060] In the thin piece 37, there is a defective part 34 where the cork is partially missing. The defective part 34 includes various types such as those originally possessed by the cork itself and those generated during processing. Therefore, the shapes and arrangements of the defective parts 34 are diverse. However, many of the defective parts 34 have a shape that is long in the second direction Y, some reach the first joining line 36, and some are located on the second joining line 38. In addition, since the cork is porous, the defective part 34 can also be in a mesh shape. It is preferable to fill such a defective part 34 with a filler as described later.

[0061] Such a cork piece 31 is cut into a specified shape and pasted on the outer peripheral surface of the grip rod body 11. As Figure 1 shown, in the present embodiment, the cork piece 31 is pasted over the entire length and the entire circumference of the grip rod body 11, covering the grip rod body 11 over the entire length and the entire circumference. In addition, the first direction X of the strip-shaped cork pieces 35 of the cork piece 31 extends along the circumferential direction. Therefore, the surface layer part 30 has a first direction part 51 in which the first direction X extends along the circumferential direction.

[0062] In Figure 7(a) schematically shows the style of the cork sheet 31 of the present embodiment. In the present embodiment, the cork sheet 31 is made into a single-piece structure, and the entire grip rod body 11 is covered by the single-piece cork sheet 31 to form the entire surface layer portion 30.

[0063] The cork sheet 31 is adhered to the radially outer side of the outer peripheral surface of the grip rod body 11. Therefore, a bonding layer 32 made of an adhesive is formed between the cork sheet 31 and the grip rod body 11 for bonding the cork sheet 31 to the grip rod body 11. When pasting the cork sheet 31 onto the grip rod body 11, the adhesive can be applied in advance to the back surface of the cork sheet 31, or conversely, the adhesive can be applied to the outer peripheral surface of the grip rod body 11, or the adhesive can be applied to both the back surface of the cork sheet 31 and the outer peripheral surface of the grip rod body 11.

[0064] The cork sheet 31 is preferably stuffed (stuffed treatment), and the surface layer portion 30 preferably has a stuffed portion. Stuffing is a process of filling the fine holes and unevenness on the surface of the cork sheet 31 with a stuffing material. As the stuffing material, various powders are appropriately used, and polishing powder is preferably used. The stuffing material is mixed with a liquid such as water and applied to the cork sheet 31, and then dried.

[0065] In addition, as described above, there is a defective portion 34 in the cork sheet 31. It is preferable to fill the defective portion 34 by stuffing. As shown in Figure 3 (a), by stuffing the defective portion 34, a first stuffed portion 61 made of a stuffing material is provided in the defective portion 34. By stuffing the surface of the cork sheet 31, the defective portion 34 is filled with the stuffing material, and the unevenness on the surface of the cork sheet 31 is flattened and smoothed by the stuffing material, thereby improving the smoothness of the surface of the cork sheet 31. The stuffing can be performed before pasting the cork sheet 31 onto the grip rod body 11, or after pasting the cork sheet 31 onto the grip rod body 11. It is preferably performed after pasting the cork sheet 31 onto the grip rod body 11.

[0066] The cork sheet 31 is wound around the grip rod body 11, and the circumferential end portions of the cork sheet 31 are overlapped and adhered to each other. The second end portion 31b is overlapped on the radially outer side of the first end portion 31a in the circumferential direction of the cork sheet 31. The first end portion 31a in the circumferential direction of the cork sheet 31 can be either of the circumferential end portions of the cork sheet 31. In the surface layer portion 30, a first overlapping portion 71 where the circumferential end portions of the cork sheet 31 are overlapped with each other is provided. The position and number of the first overlapping portion 71 are arbitrary. As an example, a structure in which the first overlapping portion 71 is provided at one place in the entire circumference is shown.

[0067] In Figure 9 shows an overview of the process when winding the cork sheet 31. First, as shown in Figure 9As shown in (a), the cork piece 31 is wound around the outer peripheral surface of the grip rod body 11, and the second end portion 31b is superposed on the radially outer side of the first end portion 31a of the cork piece 31. Although it may be in the original superposed state, it is preferably then grind the first superposed portion 71. In Figure 9 (b) shows the state of the first superposed portion 71 after grinding. In Figure 9 (b), the double-dashed line indicates the first superposed portion 71 before grinding, and the solid line indicates the first superposed portion 71 after grinding. It is preferable to perform caulking after grinding the first superposed portion 71. Caulking may be performed only in the vicinity of the first superposed portion 71, or may be performed on the entire surface of the cork piece 31. In any case, by caulking the vicinity of the first superposed portion 71, a second caulking portion 62 made of a caulking material is provided at the first superposed portion 71.

[0068] The second caulking portion 62 covers at least a part of the first superposed portion 71 and smoothes the step difference and unevenness of the first superposed portion 71. In particular, it is effective when a defective portion 34 or a crack occurs in the first superposed portion 71, that is, in the second end portion 31b in the present embodiment. The second end portion 31b is formed not only in a straight line shape but also in a serrated shape. Therefore, by caulking the first superposed portion 71, the unevenness in the surface direction and the unevenness in the thickness direction of the first superposed portion 71 are reduced, and the first superposed portion 71 becomes less prominent. In addition, in Figure 9 (b), a state in which a part of the full thickness of the second end portion 31b is ground is shown, but it may be ground over the full thickness of the second end portion 31b.

[0069] As described above, since the surface layer portion 30 made of the cork piece 31 is provided on the surface of the grip rod body 11, the fishing rod can be made lighter than the structure with a cork cylinder attached. Furthermore, unlike the cork cylinder, since the cork piece 31 is thin, the sensitivity when holding the grip rod body 11 is excellent, and vibrations are transmitted to the hand with high sensitivity. And since the cork piece 31 is adhered to the grip rod body 11 by the adhesive layer 32, the texture and color tone of the cork piece 31 are not easily damaged. In addition, since the cork piece 31 is not a piece made of crushed cork but an integrated piece, it can exhibit the same real cork feel as the cork cylinder and can present a high-class feeling. Since the defective portion 34 of the cork piece 31 is filled by the first caulking portion 61, even a thin cork piece 31 can ensure the same appearance as the cork cylinder.

[0070] In addition, since the cork piece 31 is provided at the first overlapping portion 71, the cork piece 31 can be easily pasted around the entire circumference of the grip rod body 11. It is possible to prevent gaps from being generated between the two end portions in the circumferential direction of the cork piece 31, and it is also possible to prevent the grip rod body 11 from being exposed from the gaps. In particular, this is effective when a defective portion 34 is generated at the end portion in the circumferential direction of the cork piece 31. Furthermore, since the surface layer portion 30 has the first direction portion 51, it is suitable for fishing such as repeated casting, and it is possible to prevent the cork from being defective or perforated.

[0071] In the surface layer portion 30, a first covering portion 41 that covers the first diameter-changing portion 24 and a fifth covering portion 45 that covers the second diameter-changing portion 25 are provided. In the case of a cork cylinder, since processing is difficult, it is not easy to attach a cork cylinder to the first diameter-changing portion 24 and the second diameter-changing portion 25. On the other hand, since the first covering portion 41 and the fifth covering portion 45 are composed of a relatively thin cork piece 31, it is possible to easily correspond to the shapes of the first diameter-changing portion 24 and the second diameter-changing portion 25. In particular, in the second diameter-changing portion 25, the cross-sectional shape also changes along the front-rear direction, but since it is a cork piece 31, it is possible to easily correspond to the shape change of the grip rod body 11, and it is possible to easily form the fifth covering portion 45.

[0072] Similarly, a second covering portion 42 that covers the second large-diameter portion 23 is provided in the surface layer portion 30. The second large-diameter portion 23 is a special-shaped cross-sectional portion, but since it is a cork piece 31, it is possible to easily form the second covering portion 42. And from the first large-diameter portion 21 through the small-diameter portion 22 to the second large-diameter portion 23, the outer diameter changes and the cross-sectional shape also changes, but the cork piece 31 covers the entire grip rod body 11 like this. Different from a cork cylinder, since the surface layer portion 30 is formed from a relatively thin cork piece 31, it is possible to easily correspond to the relatively large undulations on the outer peripheral surface of the grip rod body 11, and it is possible to easily provide cork on the entire surface of the grip rod body 11.

[0073] In addition, in the present embodiment, the cork piece 31 is made into a single-piece structure, but it may also be a multi-piece structure. For example, it may be a three-piece cork piece 31 that is divided into three parts front and back as shown in Figure 7 (b). In this case, a second overlapping portion (not shown) where the adjacent cork pieces 31 overlap each other front and back may also be provided in the surface layer portion 30. In addition, in addition to being divided front and back, the cork piece 31 may also be divided in the circumferential direction.

[0074] Furthermore, a cut-in portion 74 may be provided in the cork piece 31 as shown in Figure 8 (a), or it may be like Figure 8(b), a notch 75 is provided in the cork piece 31. In these cases, a third overlapping portion (not shown) where the ends of the cork pieces 31 located on both sides of the cutting portion 74 or the notch 75 overlap each other may also be provided in the surface layer portion 30.

[0075] In addition, in the above-described embodiment, the first direction X of the integrated piece provided in the surface layer portion 30 is along the first direction portion 51 in the circumferential direction, but a second direction portion 52 where the first direction X is along the front-rear direction may also be provided in the surface layer portion 30. For example, it may be as Figure 10 such that the second direction portion 52 is provided throughout the entire surface layer portion 30. In addition, Figure 10 the illustration of the first overlapping portion 71 is omitted. In this way, a fishing rod having the second direction portion 52 provided in the grip rod body 11 is suitable for fishing such as jigging where a relatively large force is likely to act in the circumferential direction, and can prevent damage and perforation of the cork. The cork piece 31 can be made into Figure 11 (a) in the form of a single-piece structure. However, it may also be as Figure 11 (b) where a three-piece structure cork piece 31 divided into three parts in the front and rear is used.

[0076] In addition, the first direction portion 51 and the second direction portion 52 may be provided in a mixed manner. For example, the grip rod body 11 may be divided into front and rear parts to provide the first direction portion 51 and the second direction portion 52. For example, it may be as Figure 12 such that the first direction portion 51 is provided in the front portion of the grip rod body 11 so as to cover the first large diameter portion 21 and the first diameter changing portion 24, and the second direction portion 52 is provided from the middle portion to the rear portion of the grip rod body 11 so as to cover the small diameter portion 22, the second diameter changing portion 25, and the second large diameter portion 23. Preferably, a second overlapping portion 72 where the ends of the cork pieces 31 overlap each other is provided at the boundary portion between the first direction portion 51 and the second direction portion 52.

[0077] Furthermore, in the above-described embodiment, the cork piece 31 covers the entire grip rod body 11, that is, the surface layer portion 30 is provided on the entire grip rod body 11, but the surface layer portion 30 may also be provided only on a part of the grip rod body 11. For example, it may be as Figure 13 such that the surface layer portion 30 is provided at the front and rear portions of the grip rod body 11, and the middle portion of the grip rod body 11 is not provided with the surface layer portion 30 so that the grip rod body 11 is exposed. In the figure, many dots are given to the exposed portion of the grip rod body 11 to indicate it. In Figure 13 (a), both the front and rear surface layer portions 30 are constituted by the first direction portion 51. In Figure 13 (b), the front surface layer portion 30 is constituted by the first direction portion 51, and the rear surface layer portion 30 is constituted by the second direction portion 52. It may also be as Figure 14In this way, the surface layer portion 30 is provided only at the front portion of the grip rod body 11, and the middle portion and the rear portion of the grip rod body 11 can also be exposed.

[0078] In addition, the grip rod body 11 of the above-described embodiment has a structure with two grip portions at the front and rear, but it may also be configured to have only a grip portion at the rear side as Figures 15 to 17 shown. The grip rod body 11 includes a small-diameter portion 22 extending rearward from the spool seat 2, a second diameter-changing portion 25 adjacently provided at the rear side of the small-diameter portion 22, and a second large-diameter portion 23 adjacently provided at the rear side of the second diameter-changing portion 25. The second large-diameter portion 23 has a special-shaped cross-sectional portion and is the grip portion. The spool seat 2 is suitable for a spinning reel. The movable cover 4 and the fixing nut 5 are located at the rear side of the spool seat body 3. The main rod body 10 and the grip rod body 11 are integrally joined to each other inside the radial direction of the spool seat 2.

[0079] A surface layer portion 30 is provided in the portion of the entire length of the grip rod body 11 that extends rearward from the spool seat 2. The surface layer portion 30 is provided over the entire small-diameter portion 22, the second diameter-changing portion 25, and the second large-diameter portion 23. Therefore, the surface layer portion 30 successively includes a fourth covering portion 44 that covers the small-diameter portion 22, a fifth covering portion 45 that covers the second diameter-changing portion 25, and a second covering portion 42 that covers the second large-diameter portion 23 from the front side.

[0080] The cork sheet 30 has a structure divided into two front and rear pieces. The front portion of the surface layer portion 30 is a first-direction portion 51. The rear portion of the surface layer portion 30 may also be a first-direction portion 51 or a second-direction portion 52, but is a third-direction portion 53 in which the first direction X of the integrated sheet is along an inclined direction inclined with respect to the front-rear direction and the circumferential direction. Preferably, at the boundary portion between the first-direction portion 51 and the third-direction portion 53, a second overlapping portion 72 where the ends of the front and rear cork sheets 31 overlap each other is provided. In addition, a first overlapping portion 71 is provided in the third-direction portion 53. Further, it is preferable to provide the cut-in portion 74 and the notch 75 as described above in the cork sheet 31 constituting the third-direction portion 53. Therefore, it is preferable to provide a third overlapping portion 73 in the third-direction portion 53. The ends of the cork sheet 31 located on both sides of the cut-in portion 74 or the notch 75 overlap each other to form the third overlapping portion 73.

[0081] In addition, in the above-described embodiment, the surface layer portion 30 is provided on the grip rod body 11, but the surface layer portion 30 may also be provided on the main rod body 10. When a grip portion is provided at a position closer to the front side than the spool seat 2, the surface layer portion 30 may also be provided on the grip portion. The surface layer portion 30 may also be provided on a portion other than the grip portion.
