Abstract
Description
Technical Field
[0001] The present invention relates to a fishing rod to which a fishing reel is attached.
Background Art
[0002] There may be a gap between the outer peripheral surface of the rod body of the fishing rod and the inner peripheral surface of the reel seat. A cylindrical spacer is used to fill this gap. The spacer is mounted between the rod body and the reel seat. However, it is necessary to prepare a spacer corresponding to the outer diameter of the rod body and the inner diameter of the reel seat. Also, depending on the shape of the outer peripheral surface of the rod body and the shape of the inner peripheral surface of the reel seat, it may be difficult to mount the spacer.

Summary of the Invention
Problems to be Solved by the Invention
[0004] An object of the present invention is to reduce the restrictions when attaching the reel seat.
Means for Solving the Problems
[0005] A fishing rod according to a first aspect of the present invention has a fishing reel attached thereto. The fishing rod includes a rod body and a reel seat. The rod body has a main body portion and a mounting portion. The main body portion contains a fiber-reinforced resin. The mounting portion is provided on the main body portion. The mounting portion contains an ultraviolet curable resin. The fishing reel is attached to the reel seat. The reel seat is mounted on the mounting portion.
[0006] According to this configuration, for example, a mounting portion can be formed on the outer peripheral surface of the main body portion by an inkjet molding machine. Therefore, the position, shape, thickness, etc. of the mounting portion can be easily set. For example, the thickness of the mounting portion can be easily set according to the outer diameter of the rod main body and the inner diameter of the reel sheet. Also, the shape of the outer peripheral surface of the rod main body and the shape of the inner peripheral surface of the reel sheet can be easily accommodated by the mounting portion. And since the gap between the outer peripheral surface of the main body portion and the inner peripheral surface of the reel sheet can be eliminated by the mounting portion, a separate spacer component is not required, and moreover, the reel sheet can be firmly mounted on the mounting portion of the rod main body.
[0007] In the fishing rod of the third aspect according to the first aspect of the present invention, the mounting portion has an axially convex portion. The axially convex portion extends in the axial direction of the main body portion. For example, when forming the mounting portion by an inkjet molding machine, the mounting portion can be easily formed on the outer peripheral surface of the main body portion by relatively moving the head of the inkjet molding machine along the axial direction of the main body portion.
[0008] In the fishing rod of the fourth aspect according to the second aspect of the present invention, the shape of the axially convex portion changes along the axial direction of the main body portion. Note that the shape changing means that the width of the axially convex portion increases or decreases along the axial direction of the main body portion, or the height of the axially convex portion increases or decreases along the axial direction of the main body portion. According to this configuration, the shape of the mounting portion can be easily accommodated to the inner peripheral surface of the reel sheet.
[0009] In the fishing rod of the fourth aspect according to the second or third aspect of the present invention, the axial convex portion has at least two first axial convex portions and a second axial convex portion. The first axial convex portion and the second axial convex portion are arranged in the circumferential direction of the main body portion. According to this configuration, since the first axial convex portion and the second axial convex portion are separated from each other in the circumferential direction of the main body portion, the manufacturing time of the mounting portion can be shortened, and the mounting portion can be made lighter. Further, the space between the first axial convex portion and the second axial convex portion can also be used as an adhesive reservoir. When the space between the first axial convex portion and the second axial convex portion is used as an adhesive reservoir, the reel sheet can be adhered to the mounting portion more firmly.
[0010] In the fishing rod of the fifth aspect according to the fourth aspect of the present invention, the first axial convex portion and the second axial convex portion have different shapes from each other. According to this configuration, the shape of the mounting portion can be easily adapted to the inner peripheral surface of the reel sheet.
[0011] In the fishing rod of the sixth aspect according to any one of the first to fifth aspects of the present invention, the mounting portion has a circumferential convex portion. The circumferential convex portion extends in the circumferential direction of the main body portion. For example, when forming the mounting portion by an inkjet molding machine, the mounting portion can be easily formed by relatively moving the head of the inkjet molding machine along the circumferential direction of the main body portion. For example, by rotating the rod body in the circumferential direction of the main body portion, the head of the inkjet molding machine can be relatively moved along the circumferential direction of the main body portion.
[0012] In the fishing rod of the seventh aspect according to the sixth aspect of the present invention, the shape of the circumferential convex portion changes along the circumferential direction of the main body portion. According to this configuration, the shape of the mounting portion can be easily adapted to the inner peripheral surface of the reel sheet.
[0013] In the fishing rod of the eighth aspect according to the sixth or seventh aspect of the present invention, the circumferential convex portion has at least two first circumferential convex portions and a second circumferential convex portion. The first circumferential convex portion and the second circumferential convex portion are arranged in the axial direction of the main body portion. According to this configuration, since the first circumferential convex portion and the second circumferential convex portion are separated from each other in the axial direction of the main body portion, the manufacturing time of the mounting portion can be shortened, and the mounting portion can be lightened. Further, the space between the first circumferential convex portion and the second circumferential convex portion can also be used as an adhesive reservoir. When the space between the first circumferential convex portion and the second circumferential convex portion is used as an adhesive reservoir, the reel sheet can be adhered to the mounting portion more firmly.
[0014] In the fishing rod of the ninth aspect according to the eighth aspect of the present invention, the first circumferential convex portion and the second circumferential convex portion have different shapes from each other. According to this configuration, the shape of the mounting portion can be easily adapted to the inner peripheral surface of the reel sheet.
[0015] In the fishing rod of the tenth aspect according to any one of the first to ninth aspects of the present invention, the mounting portion has a spiral convex portion. The spiral convex portion extends in the spiral direction of the main body portion. The spiral direction is a direction intersecting the axial direction and the circumferential direction of the main body portion. For example, when forming the mounting portion by an inkjet molding machine, the mounting portion can be easily formed on the outer peripheral surface of the main body portion by relatively moving the head of the inkjet molding machine along the axial direction of the main body portion and relatively moving it along the circumferential direction of the main body portion. For example, the spiral convex portion can be formed by moving the head of the inkjet molding machine along the axial direction of the main body portion while rotating the rod body in the circumferential direction of the main body portion.
[0016] In the fishing rod of the eleventh aspect according to the tenth aspect of the present invention, the shape of the spiral convex portion changes along the spiral direction of the main body portion. According to this configuration, the shape of the mounting portion can be easily adapted to the inner peripheral surface of the reel sheet.
[0017] In the fishing rod of the twelfth aspect according to the tenth or eleventh aspect of the present invention, the spiral convex portions have a first spiral convex portion and a second spiral convex portion that intersect each other. According to this configuration, it becomes difficult for the reel seat to rotate in the circumferential direction of the main body portion with respect to the mounting portion. Therefore, the reel seat can be firmly mounted on the mounting portion. Further, the space between the first spiral convex portion and the second spiral convex portion can also be used as an adhesive reservoir. When it is used as the adhesive reservoir in this way, the reel seat can be adhered to the mounting portion more firmly.
[0018] In the fishing rod of the thirteenth aspect according to the twelfth aspect of the present invention, the first spiral convex portion and the second spiral convex portion have different shapes from each other. According to this configuration, the shape of the mounting portion can be easily made to correspond to the inner peripheral surface of the reel seat.
Effect of the Invention
[0019] As described above, since the mounting portion containing the ultraviolet curable resin is provided on the rod body, the reel seat can be mounted on the rod body without using a spacer as a separate member. Further, the mounting portion can be easily formed corresponding to the reel seat. Therefore, the restrictions when mounting the reel seat on the rod body can be reduced.

Mode for Carrying Out the Invention
[0021] <First Embodiment> The fishing rod according to the first embodiment of the present invention is shown in FIG. 1. A fishing reel is attached to the fishing rod. The type of the fishing rod is arbitrary and may be a casting rod, a telescopic rod, or a so-called one-piece rod consisting of a single rod body. It may be an external guide type fishing rod or a through-tubing rod. The fishing reel may be a double-bearing reel or a spinning reel. In this embodiment, as an example, a fishing rod suitable for a double-bearing reel is shown. The double-bearing reel is located above the fishing rod in the use state. Note that 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, when the mounting portion 11 described later has a convex portion, the dimension in the longitudinal direction (extending direction) of the convex portion is referred to as the length, the dimension in the short direction of the convex portion is referred to as the width, and the dimension in the radial direction (projection amount) of the fishing rod at the convex portion is referred to as the thickness. Note that the circumferential direction of the fishing rod is simply referred to as the circumferential direction.
[0022] The fishing rod includes a rod body 1 and a reel seat 2. In FIG. 1, the reel seat 2 is shown by a two-dot chain line. Note that in FIG. 1, only the reel seat body 3 of the reel seat 2 is shown. The reel seat body 3 is cylindrical and is a so-called pipe seat. The reel seat 2 includes the reel seat body 3, a fixed hood, a movable hood (not shown), and a fixing nut. The fixed hood 4 is integrally formed with the reel seat body 3. The fixed hood 4 is provided on the upper surface of the reel seat body 3 and holds the rear end portion of the reel leg of the reel. The movable hood is attached to the outer peripheral surface of the reel seat body 3. The movable hood is cylindrical. The movable hood is located away from the front side of the fixed hood 4 and holds the front end portion of the reel leg. The reel leg is clamped front and rear by the movable hood and the fixed hood 4. A male screw portion (not shown) is formed on the outer peripheral surface of the reel seat body 3, and the fixing nut is screwed onto the male screw portion. The fixing nut is located on the front side of the movable hood and moves the movable hood back and forth. Further, the reel seat body 3 is provided with a trigger 5 for hooking a finger on the lower surface.
[0023] The rod body 1 includes a main body portion 10 and a mounting portion 11. The main body portion 10 is a so-called blank. The main body portion 10 is made of a fiber-reinforced resin and may be cylindrical, that is, hollow, or solid. In this embodiment, the main body portion 10 is hollow. The reinforcing fiber of the main body portion 10 is, for example, carbon fiber.
[0024] The mounting portion 11 is provided on the outer peripheral surface of the main body portion 10. The mounting portion 11 is provided only at a predetermined location among the entire length of the main body portion 10. The reel sheet 2 is mounted on the mounting portion 11. Specifically, the reel sheet main body 3 is adhesively fixed to the mounting portion 11. Therefore, the mounting portion 11 is formed at the location where the reel sheet 2 is attached among the entire length of the main body portion 10. The length of the mounting portion 11 corresponds to the length of the reel sheet 2, and specifically, corresponds to the length of the reel sheet main body 3.
[0025] The mounting portion 11 is formed so as to fill the gap between the inner peripheral surface 2a of the reel sheet 2 (reel sheet main body 3) and the outer peripheral surface 10a of the main body portion 10. The shape, arrangement, etc. of the mounting portion 11 are arbitrary. For example, it may be provided over the entire length of the mounting location of the reel sheet 2 on the main body portion 10, or may be provided only on a part of the entire length of the mounting location of the reel sheet 2 on the main body portion 10. Also, it may be provided over the entire circumference of the mounting location of the reel sheet 2 on the main body portion 10, or may be provided only on a part of the entire circumference of the mounting location of the reel sheet 2 on the main body portion 10.
[0026] Preferably, the mounting portion 11 has a convex portion. Specifically, the mounting portion 11 has a ridge extending in a predetermined direction. In the present embodiment, the mounting portion 11 has a plurality of axial convex portions 20 linearly extending in the front-rear direction. The axial convex portions 20 are arranged at intervals in the circumferential direction. The axial convex portions 20 project radially outward from the outer peripheral surface 10a of the main body portion 10. The number of the axial convex portions 20 is arbitrary, but in this embodiment, there are four, and they are arranged at 90-degree intervals. That is, the axial convex portions 20 are composed of a first axial convex portion 21, a second axial convex portion 22, a third axial convex portion 23, and a fourth axial convex portion 24. The first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24 are arranged at equal intervals and are arranged every 90 degrees.
[0027] The first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24 all have the same shape, and the length, width, and thickness are all the same. The first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24 have a constant width and a constant thickness. The first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24 are formed over the entire length of the corresponding range of the reel sheet 2.
[0028] In addition, the portion of the mounting location of the reel sheet 2 where the mounting portion 11 is not provided becomes a relative concave portion that is recessed radially inward relative to the mounting portion 11. That is, between the circumferential directions of the first axial convex portion 21 and the second axial convex portion 22, between the circumferential directions of the second axial convex portion 22 and the third axial convex portion 23, between the circumferential directions of the third axial convex portion 23 and the fourth axial convex portion 24, and between the fourth axial convex portion 24 and the first axial convex portion 21, the mounting portion 11 is not provided respectively. Therefore, between the circumferential directions of the first axial convex portion 21 and the second axial convex portion 22, between the circumferential directions of the second axial convex portion 22 and the third axial convex portion 23, between the circumferential directions of the third axial convex portion 23 and the fourth axial convex portion 24, and between the fourth axial convex portion 24 and the first axial convex portion 21, relative concave portions are formed respectively. Before the reel sheet 2 is mounted, the outer peripheral surface 10a of the main body portion 10 is exposed in the relative concave portion.
[0029] The arrangement of the first-axis convex portion 21, the second-axis convex portion 22, the third-axis convex portion 23, and the fourth-axis convex portion 24 is arbitrary, but preferably, the first-axis convex portion 21 is arranged at the uppermost part of the entire circumference of the outer peripheral surface 10a of the main body portion 10. The second-axis convex portion 22 and the fourth-axis convex portion 24 are respectively arranged on the left and right side portions of the outer peripheral surface 10a of the main body portion 10 and face each other at 180 degrees. The third-axis convex portion 23 is arranged at the lowermost part of the entire circumference of the outer peripheral surface 10a of the main body portion 10 and faces the first-axis convex portion 21 at 180 degrees. In other words, the first-axis convex portion 21 is arranged on the upper surface of the main body portion 10, the second-axis convex portion 22 and the third-axis convex portion 23 are arranged on the left and right side surfaces of the main body portion 10, and the fourth-axis convex portion 24 is arranged on the lower surface of the main body portion 10. By arranging the first-axis convex portion 21 on the upper surface, particularly the uppermost part, of the main body portion 10, the reel legs fixed by the movable hood and the fixed hood 4 are stabilized, and the reel can be stabilized. Also, by arranging the third-axis convex portion 23 on the lower surface, particularly the lowermost part, of the main body portion 10, the trigger 5 is stabilized. Furthermore, by arranging the second-axis convex portion 22 and the fourth-axis convex portion 24 on the left and right side surfaces of the main body portion 10 respectively, the reel sheet 2 is less likely to sway left and right.
[0030] As shown in Fig. 1(b), the inner peripheral surface 2a of the reel sheet 2 is adhered to the outer surfaces (radially outer surfaces) of the first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24. Therefore, as shown in Fig. 2(a), between each outer surface of the first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24 and the inner peripheral surface 2a of the reel sheet 2, a first adhesive portion 31 made of an adhesive for adhering the inner peripheral surface 2a of the reel sheet 2 and the outer surface of the mounting portion 11 is provided. Further, a space 33 is formed between the outer peripheral surface 10a of the main body portion 10 and the inner peripheral surface 2a of the reel sheet 2 between the circumferential directions of the first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24. This space 33 can be used as an adhesive reservoir. The case where the space 33 is used as an adhesive reservoir is shown in Fig. 2(b). In this case, a second adhesive portion 32 made of an adhesive for adhering the inner peripheral surface 2a of the reel sheet 2 and the outer peripheral surface 10a of the main body portion 10 is provided in the space 33. The second adhesive portion 32 fills the space 33. The second adhesive portion 32 is continuous with the first adhesive portion 31.
[0031] The mounting portion 11 can be formed, for example, using an inkjet molding machine (printing machine), a dispenser, or the like. As an example, the outline of an inkjet molding machine is shown in FIG. 3. The inkjet molding machine includes a tank 100 that stores an ink coating material, and a head 101 that applies the ink coating material supplied from the tank 100 to an object. The basic color inks are cyan-based, magenta-based, yellow-based, and black-based inks. However, white, silver, or the like may be used if necessary. A plurality of discharge nozzles for supplying cyan-based, magenta-based, yellow-based, and black-based inks as droplets are arranged in the head 101. A large number of ejection holes are provided in each discharge nozzle. Further, the inkjet molding machine is provided with a heating medium. The heating medium receives operation information from control means (not shown), rapidly heats the ink to promote droplet formation, and ejects it by bubbles. This method is called the thermal jet method. However, the piezo method may be adopted. Furthermore, the inkjet molding machine is provided with an ultraviolet irradiation device 102. The rod body 1 is attached to the mandrel 103. Then, the head 101 is moved along the axis of the mandrel 103. The coating form can be a multi-pass method. In the multi-pass method, the head 101 does not perform coating in one stroke, but moves to the same location multiple times to perform coating. The number of passes is arbitrary. By rotating the mandrel 103 around its axis, the rod body 1 can be rotated together with the mandrel 103.
[0032] Droplets of UV ink are ejected from the discharge nozzles, and the ink is cured and fixed by irradiating ultraviolet rays from the ultraviolet irradiation device 22. By adjusting the viscosity of this UV ink, the time from when the ejected ink droplets adhere until ultraviolet irradiation, and the amount of ultraviolet light, the shape, thickness, etc. of the mounting portion 11 can be adjusted. The UV ink may be of the photopolymerization type and contains a resin that cures by ultraviolet rays. The ultraviolet curable resin may be various radical polymerization resins and may be various oligomers and monomers.
[0033] <Second Embodiment> Figure 4 shows the main part of the fishing rod in the second embodiment. In the above-described first embodiment, the first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24 were continuous in the front-rear direction. However, in the present embodiment, the first axial convex portion 21, the second axial convex portion 22, the third axial convex portion 23, and the fourth axial convex portion 24 are divided front and rear and have a discontinuous configuration. The number of divisions is arbitrary, but in this embodiment, it is two. However, the number of divisions may be three or more. Thus, the axial convex portion 20 does not have to be continuous in the front-rear direction and may be discontinuous in the front-rear direction. That is, the axial convex portion 20 may be provided fragmentarily in the front-rear direction. Incidentally, all of the plurality of axial convex portions 20 may be discontinuous in the front-rear direction, or only a part of the plurality of axial convex portions 20 may have a discontinuous shape in the front-rear direction. Also, in the plurality of axial convex portions 20, the number of divisions may be the same as each other or may be different from each other.
[0034] <The Third Embodiment> Figure 5(a) shows the main part of the fishing rod in the third embodiment. Figure 5(a) shows only the axial convex portion 20. In the above-described first and second embodiments, the width of the axial convex portion 20 was constant along the front-rear direction. However, in the present embodiment, the width of the axial convex portion 20 changes along the front-rear direction. An example is shown in Figure 5(a). The width of the first axial convex portion 21 expands toward the rear side. The first axial convex portion 21 has a triangular shape, specifically, an isosceles triangle with the front end as the apex and the rear end as the base. The width of the second axial convex portion 22 adjacent to the first axial convex portion 21, contrary to the first axial convex portion 21, shrinks toward the rear side. The second axial convex portion 22 has a triangular shape similar to the first axial convex portion 21, but is an isosceles triangle with the front end as the base and the rear end as the apex. Thus, the width of the axial convex portion 20 may expand and contract along the front-rear direction. The width of the axial convex portion 20 may expand to the middle of the front-rear direction and then shrink.
[0035] <The Fourth Embodiment> Fig. 5(b) shows the main part of the fishing rod in the fourth embodiment. In the above embodiment, the thickness of the axial convex portion 20 was constant along the front-rear direction, but in this embodiment, the thickness of the axial convex portion 20 changes along the front-rear direction. An example is shown in Fig. 5(b). The thickness of the first axial convex portion 21 increases toward the rear side. The second axial convex portion 22 is arranged to face the first axial convex portion 21 at 180 degrees. The thickness of the second axial convex portion 22 decreases toward the rear side, contrary to the first axial convex portion 21. Thus, the thickness of the axial convex portion 20 may increase and decrease along the front-rear direction. The thickness of the axial convex portion 20 may increase to the middle of the front-rear direction and then decrease.
[0036] <The Fifth Embodiment> Fig. 6 shows the main part of the fishing rod in the fifth embodiment. The mounting portion 11 in this embodiment has a circumferential convex portion 40 extending in the circumferential direction of the main body portion 10. The circumferential convex portion 40 is provided at a plurality of locations at intervals in the front-rear direction. The number of the circumferential convex portions 40 is arbitrary, but in this embodiment, there are five as shown in Fig. 6(a). That is, the mounting portion 11 has a first circumferential convex portion 41, a second circumferential convex portion 42, a third circumferential convex portion 43, a fourth circumferential convex portion 44, and a fifth circumferential convex portion 45. The first to fifth circumferential convex portions 41, 42, 43, 44, and 45 all have the same shape, and the circumferential length, width, and thickness are all the same. That is, the first to fifth circumferential convex portions 41, 42, 43, 44, and 45 have a constant width and a constant thickness. As shown in Fig. 6(b), the first to fifth circumferential convex portions 41, 42, 43, 44, and 45 are continuously formed over the entire circumference of the outer peripheral surface 10a of the main body portion 10. Therefore, the first to fifth circumferential convex portions 41, 42, 43, 44, and 45 are annular.
[0037] <The Sixth Embodiment> Fig. 7(a) shows the main part of the fishing rod in the sixth embodiment. In the above fifth embodiment, the width of the circumferential convex portion 40 was constant along the circumferential direction. However, in this embodiment, the width of the circumferential convex portion 40 changes along the circumferential direction. As an example, the width of the first circumferential convex portion 41 is the smallest at the uppermost part and the largest at the lowermost part, and gradually expands from the uppermost part to the lowermost part. The width of the second circumferential convex portion 42 adjacent to the first circumferential convex portion 41 is, contrary to the first circumferential convex portion 41, the largest at the uppermost part and the smallest at the lowermost part, and shrinks from the uppermost part to the lowermost part. Thus, the width of the circumferential convex portion 40 may expand and contract along the circumferential direction.
[0038] <Seventh Embodiment> Fig. 7(b) shows the main part of the fishing rod in the seventh embodiment. In this embodiment, the thickness of the circumferential convex portion 40 changes along the circumferential direction. As an example, the thickness of the circumferential convex portion 40 is the largest at the uppermost and lowermost parts and the smallest at both left and right side parts. Thus, the thickness of the circumferential convex portion 40 may increase and decrease along the circumferential direction.
[0039] In addition, when the inner circumferential surface 2a of the reel sheet 2 is circular, as shown in Fig. 6(b), it is preferable that the thickness of the circumferential convex portion 40 is constant along the circumferential direction. On the other hand, when the inner circumferential surface 2a of the reel sheet 2 is non-circular, it is preferable that the thickness of the circumferential convex portion 40 changes along the circumferential direction. For example, in the case of Fig. 7(b), it can easily correspond to the inner circumferential surface 2a of the reel sheet 2 being an ellipse that is long in the vertical direction.
[0040] <Eighth Embodiment> FIG. 8 shows the main part of the fishing rod in the eighth embodiment. In the fifth to seventh embodiments described above, the circumferential convex portion 40 was continuous over the entire circumference of the outer peripheral surface 10a of the main body portion 10. However, in the present embodiment, the circumferential convex portion 40 is divided vertically and has a discontinuous configuration. The number of divisions is arbitrary, but in this embodiment, it is two. However, the number of divisions may be three or more. Thus, the circumferential convex portion 40 does not have to be annular and may be provided fragmentarily in the circumferential direction. Also, only one location out of the entire circumference may be discontinuous, and the number of discontinuous locations may be plural or one. Note that all of the plurality of circumferential convex portions 40 may be discontinuous, or only a part of the plurality of circumferential convex portions 40 may have a discontinuous shape.
[0041] Note that the thickness of the circumferential convex portion 40 may be constant along the circumferential direction as shown in FIG. 8(b), or may vary in the circumferential direction as shown in FIG. 8(c). When the thickness of the circumferential convex portion 40 is constant along the circumferential direction as shown in FIG. 8(b), the first center 12a of the virtual circle 12 defined by the outer surface of the circumferential convex portion 40 coincides with the second center 10b of the outer peripheral surface 10a of the main body portion 10. On the other hand, when the thickness of the circumferential convex portion 40 varies in the circumferential direction as shown in FIG. 8(c), the first center 12a is displaced and does not coincide with the second center 10b. Therefore, the reel seat 2 can be eccentrically displaced in a predetermined radial direction with respect to the rod main body 1. Further, by changing the thickness of the circumferential convex portion 40 along the circumferential direction, it is possible to easily cope with a shape in which the inner peripheral surface 2a of the reel seat 2 is long in the left-right direction, for example, an elliptical shape.
[0042] <The Ninth Embodiment> Figs. 9(a) and (b) show the main part of the fishing rod in the ninth embodiment. The mounting portion 11 in this embodiment has a spiral convex portion 50 extending in the spiral direction of the main body portion 10. The spiral direction of the spiral convex portion 50 intersects with the front-rear direction and the circumferential direction. That is, the spiral direction is a direction inclined with respect to the front-rear direction and the circumferential direction. The direction of rotation, lead, pitch, etc. of the spiral direction are arbitrary. The direction of rotation of the spiral is counterclockwise when viewed from the front side to the rear side (right side of the paper) in Fig. 9(a), and clockwise when viewed from the front side to the rear side in Fig. 9(b). Also, in Fig. 9(a), the pitch and lead are shown to be relatively narrow, and in Fig. 9(b), the pitch and lead are shown to be relatively wide. Thus, the pitch and lead of the spiral can be various. Also, the spiral convex portion 50 shown in Figs. 9(a) and (b) is one. Therefore, the spiral convex portion 50 has a single-thread configuration. Furthermore, the number of turns (number of threads) of the spiral of the spiral convex portion 50 is also arbitrary. For example, in the spiral convex portion 50 shown in Fig. 9(b), the number of turns is two and a half rotations.
[0043] <Tenth Embodiment> Fig. 9(c) shows the main part of the fishing rod in the tenth embodiment. In the ninth embodiment shown in Figs. 9(a) and (b), the spiral convex portion 50 was one, but the spiral convex portion 50 may be a plurality. As an example, Fig. 9(c) shows a configuration in which there are two spiral convex portions 50. That is, the spiral convex portion 50 has a first spiral convex portion 51 and a second spiral convex portion 52. The direction of rotation of the spiral of both the first spiral convex portion 51 and the second spiral convex portion 52 is counterclockwise when viewed from the front side to the rear side, and they are equal to each other. On the other hand, the first spiral convex portion 51 and the second spiral convex portion 52 are shifted in phase by 180 degrees with respect to each other. That is, in this embodiment, the spiral convex portion 50 has a double-thread configuration. Thus, the spiral convex portion 50 may have a multi-thread configuration instead of a single-thread configuration.
[0044] <Eleventh Embodiment> Fig. 10(a) shows the main part of the fishing rod in the 11th embodiment. In the 10th embodiment shown in Fig. 9(c), the spiral convex part 50 has a double-threaded screw configuration, and the rotation directions of the spirals of the first spiral convex part 51 and the second spiral convex part 52 are the same as each other. However, in this embodiment, the rotation directions of the spirals of the first spiral convex part 51 and the second spiral convex part 52 are different from each other. That is, the rotation direction of the spiral of the first spiral convex part 51 is counterclockwise when viewed from the front side to the rear side, and the rotation direction of the spiral of the second spiral convex part 52 is clockwise when viewed from the front side to the rear side. Thus, since the rotation directions of the spirals of the first spiral convex part 51 and the second spiral convex part 52 are opposite to each other, a first intersection part 61 where the first spiral convex part 51 and the second spiral convex part 52 intersect is formed. In this embodiment, the first intersection parts 61 are alternately formed at positions facing each other 180 degrees along the front-rear direction. Therefore, the first intersection parts 61 are provided, for example, on both the left and right side parts of the main body part 10, or on the uppermost part and the lowermost part.
[0045] <The 12th Embodiment> Fig. 10(b) shows the main part of the fishing rod in the 12th embodiment. In this embodiment, in addition to the first spiral convex part 51 and the second spiral convex part 52 in the above-described 11th embodiment, a third spiral convex part 53 and a fourth spiral convex part 54 are provided. The rotation direction of the spiral of the third spiral convex part 53 is the same as that of the first spiral convex part 51, and the phase is shifted by 180 degrees from the first spiral convex part 51. The rotation direction of the spiral of the fourth spiral convex part 54 is the same as that of the second spiral convex part 52, and the phase is shifted by 180 degrees from the second spiral convex part 52. In this embodiment, in addition to the first intersection part 61, a second intersection part 62 where the third spiral convex part 53 and the fourth spiral convex part 54 intersect is formed. Further, a third intersection part 63 where the second spiral convex part 52 and the third spiral convex part 53 intersect is formed, and a fourth intersection part 64 where the first spiral convex part 51 and the fourth spiral convex part 54 intersect is formed.
[0046] For example, at the uppermost and lowermost portions of the main body 10, a third intersection portion 63 and a fourth intersection portion 64 are alternately formed along the front-rear direction. A fourth intersection portion 64 is provided at the lowermost portion of the main body 10 corresponding to the third intersection portion 63 at the uppermost portion of the main body 10, and a third intersection portion 63 is provided at the lowermost portion of the main body 10 corresponding to the fourth intersection portion 64 at the uppermost portion of the main body 10. Further, at both the left and right side portions of the main body 10, a first intersection portion 61 and a second intersection portion 62 are alternately formed along the front-rear direction. A second intersection portion 62 is provided at the right side portion of the main body 10 corresponding to the first intersection portion 61 at the left side portion of the main body 10, and a first intersection portion 61 is provided at the right side portion of the main body 10 corresponding to the second intersection portion 62 at the left side portion of the main body 10.
[0047] <The 13th Embodiment> FIG. 10(c) shows the main part of the fishing rod in the 13th embodiment. In this embodiment, the mounting portion 11 has an axial convex portion 20, a circumferential convex portion 40, and a spiral convex portion 50, and moreover, the axial convex portion 20, the circumferential convex portion 40, and the spiral convex portion 50 are all of a discontinuous configuration. Specifically, in the above-described 12th embodiment, the first to fourth spiral convex portions 51, 52, 53, 54 continuously extended along the spiral direction, but in this embodiment, the first to fourth spiral convex portions 51, 52, 53, 54 are discontinuously provided along the spiral direction. And at the locations of the first intersection portion 61 and the second intersection portion 62 in the 12th embodiment, instead of the first intersection portion 61 and the second intersection portion 62, a circumferential convex portion 40 is provided only for a predetermined length in the circumferential direction. Also, at the locations of the third intersection portion 63 and the fourth intersection portion 64 in the 12th embodiment, instead of the third intersection portion 63 and the fourth intersection portion 64, an axial convex portion 20 is provided only for a predetermined length in the front-rear direction. In this way, the discontinuous axial convex portion 20, circumferential convex portion 40, and spiral convex portion 50 can form an octagonal-pattern mounting portion 11. The octagonal pattern can be a regular octagon, or can also be an octagon that is long in the front-rear direction or the circumferential direction. In this way, since the mounting portion 11 can be made into a honeycomb structure, weight reduction can be achieved, the reel sheet 2 can be firmly supported from the radially inner side, and the reel sheet 2 can be firmly attached to the rod main body 1.
[0048] <Embodiment No. 14> FIG. 11 shows the main part of the fishing rod in the 14th embodiment. This embodiment is a modified example of the 11th embodiment shown in FIG. 10(a). That is, in the above-described 11th embodiment, the first spiral convex portion 51 and the second spiral convex portion 52 were formed to have the same width as each other, but in this embodiment, the widths of the first spiral convex portion 51 and the second spiral convex portion 52 are different from each other. An example is shown in FIG. 11, and the width of the first spiral convex portion 51 is wider than the width of the second spiral convex portion 52. Thus, the first spiral convex portion 51 and the second spiral convex portion 52 may have different widths from each other, or may have different heights from each other.
[0049] <Embodiment No. 15> FIG. 12 shows the main part of the fishing rod in the 15th embodiment. This embodiment is a modified example of the 1st embodiment shown in FIG. 1(b). That is, in the above-described 1st embodiment, the first to fourth axial convex portions 24 were all formed to have the same height, but in this embodiment, the heights of the first to fourth axial convex portions 24 are different from each other. An example is shown in FIG. 12. The height of the second axial convex portion 22 is the lowest, the heights of the first axial convex portion 21 and the third axial convex portion 23 are intermediate heights, and further, the height of the fourth axial convex portion 24 is the highest. That is, in the order of the second axial convex portion 22, the first axial convex portion 21 and the third axial convex portion 23, and the fourth axial convex portion 24, the height increases. In this case, the first center 12a of the virtual circle 12 defined by the outer surfaces of the first to fourth axial convex portions 24 is displaced with respect to the second center 10b of the outer peripheral surface 10a of the main body portion 10. Therefore, the reel seat 2 can be eccentrically oriented in a predetermined radial direction with respect to the rod main body 1.
