Summary of the Invention

Problems to be Solved by the Invention

[0004] In the fishing rod of Patent Document 1, since a spacer is interposed in the gap between the rod blank and the reel seat, there is a problem that the number of parts and the weight increase. Further, in the assembly process of the fishing rod, since two adhesive steps of fixing the spacer to the rod blank with an adhesive and fixing the reel seat to the spacer with an adhesive are required, there is a problem that the overall assembly time becomes long and the cost increases. Furthermore, there is also a possibility that the vibration transmitted from the rod blank to the reel seat during actual fishing is attenuated by the spacer, resulting in a decrease in sensitivity.

[0005] The present invention has been made to solve the above problems, and an object thereof is to provide a fishing rod that can shorten the assembly time while achieving weight reduction and has good sensitivity.

Means for Solving the Problems

[0006] In order to solve the above problems, the present invention provides a fishing rod including a front rod, a rear rod, and a cylindrical reel sheet, wherein the front rod and the rear rod are adhered to the inner peripheral surface of the reel sheet. The rear portion of the front rod and the front portion of the rear rod have an enlarged diameter corresponding to the inner peripheral surface of the reel sheet.

[0007] In the present invention, the rear portion of the front rod and the front portion of the rear rod can be directly adhered to the inner peripheral surface of the reel sheet. Therefore, it is not necessary to interpose a spacer for fixing the reel sheet and the rod, and the number of parts can be reduced and the weight can be reduced. In addition, since the bonding process of the spacer can be eliminated, the assembly time can be shortened and the cost can be reduced. Further, since vibration is directly transmitted from the front rod to the reel sheet, the sensitivity during actual fishing is good.

[0008] Further, it is preferable that the rear portion of the front rod and the front portion of the rear rod are joined to each other by an adhesive.

[0009] With this configuration, the rear portion of the front rod and the front portion of the rear rod can be directly joined inside the reel sheet, so that the strength can be improved. In addition, since vibration is directly transmitted from the rear portion of the front rod and the front portion of the rear rod to the reel sheet, the sensitivity during actual fishing is good.

[0010] Further, the reel sheet is provided with a clamping region where the mounting leg portion of the fishing reel is clamped, and it is preferable that the rear portion of the front rod and the front portion of the rear rod are joined at a position corresponding to the clamping region.

[0011] With this configuration, the joining portion between the rear portion of the front rod and the front portion of the rear rod can be reinforced by the mounting leg portion, so that the strength of the fishing rod can be improved.

[0012] Further, it is preferable that the rear portion of the front rod and the front portion of the rear rod are joined to each other by an adhesive in an inlay joint structure or an end-to-end joint structure.

[0013] In this configuration, since the rear part of the front rod and the front part of the rear rod can be directly joined inside the reel seat, the strength of the fishing rod can be improved. Also, since vibration is transmitted from the front rod to the rear rod by the in-line joint structure or the side-by-side joint structure, vibration is transmitted from both the front rod and the rear rod to the reel seat. Therefore, the sensitivity during actual fishing is good.

[0014] Further, on the inner peripheral surface of the reel seat, a protrusion protruding radially inward is formed, and it is preferable that the rear part of the front rod and the front part of the rear rod are in contact with the protrusion.

[0015] In this configuration, since the rear part of the front rod and the front part of the rear rod can be adhered to the inner peripheral surface of the reel seat so as to be applied to the protrusion, the assembling work of the front rod and the rear rod to the reel seat is easy to perform. Therefore, productivity can be improved.

[0016] Further, it is preferable that the outer diameters of the rear part of the front rod and the front part of the rear rod are different from each other.

[0017] In this configuration, variations can be provided in the structure of directly adhering the rear part of the front rod and the front part of the rear rod to the inner peripheral surface of the reel seat, and the appearance of the exposed part can also be changed. Thereby, a fishing rod can be configured according to the fishing species.

[0018] Further, it is preferable that at least one of the rear part of the front rod and the front part of the rear rod is formed such that the thickness becomes thinner toward the insertion end when inserted into the inner peripheral surface of the reel seat.

[0019] In this configuration, weight reduction can be achieved while ensuring a predetermined strength.

[0020] Further, it is preferable that the rear part of the front rod and the front part of the rear rod are arranged at intervals in the axial direction of the reel seat.

[0021] In this configuration, since it is not necessary to join the rear part of the front rod and the front part of the rear rod inside the reel sheet, the adhesive for joining becomes unnecessary accordingly. As a result, cost reduction can be achieved.

Advantages of the Invention

[0022] According to the fishing rod of the present invention, it is possible to shorten the assembly time while achieving weight reduction, and to provide a fishing rod with good sensitivity.

Modes for Carrying Out the Invention

[0024] Next, embodiments of the fishing rod of the present invention will be described in detail with reference to the drawings as appropriate. In the following description, "front" means the tip side, and "rear" means the butt side. In each embodiment, the same members may be omitted in terms of reference numerals and explanations. Note that the cross-sectional views in each embodiment are schematic diagrams, and the sizes, shapes, etc. of each part are appropriately simplified for easy understanding.

[0025] (First Embodiment) FIG. 1 is a cross-sectional view showing a main part of a fishing rod 1 according to the first embodiment of the present invention. As shown in FIG. 1, the fishing rod 1 includes a front rod 10, a rear rod 20, and a cylindrical reel seat 30. The front rod 10 and the rear rod 20 are directly adhered to the cylindrical inner peripheral surface 35 formed in the reel seat 30 by an adhesive.

[0026] The front rod 10 and the rear rod 20 are configured as tubular bodies (hollow bodies) made of fiber-reinforced resin. The front rod 10 and the rear rod 20 are formed, for example, by winding a fiber-reinforced resin prepreg (prepreg sheet) impregnated with a synthetic resin such as an epoxy resin around a mandrel with reinforcing fibers (mainly carbon fibers, glass fibers, etc.), and then undergoing a process of removing the mandrel after a heating process.

[0027] The front rod 10 includes a front rod main body portion 11 and a rear portion 12 continuous with the rear end portion of the front rod main body portion 11. The rear rod 20 includes a rear rod main body portion 21 and a front portion 22 continuous with the front end portion of the rear rod main body portion 21. The rear portion 12 of the front rod 10 and the front portion 22 of the rear rod 20 are expanded in diameter to an outer diameter corresponding to the inner diameter of the inner peripheral surface 35 of the reel seat 30.

[0028] The front rod body portion 11 is a cylindrical rod portion having a small diameter throughout the axial direction, and has an outer diameter smaller than the inner diameter of the inner peripheral surface 35 of the reel seat 30. The rear portion 12 includes a first inclined portion 13 continuous with the rear end portion of the front rod body portion 11, and a first large-diameter portion 14 continuous with the rear end portion 13a of the first inclined portion 13. The first inclined portion 13 has a funnel shape (substantially conical shape) that gradually increases in diameter toward the rear. The outer diameter of the front end portion of the first inclined portion 13 corresponds to the outer diameter of the front rod body portion 11, and the outer diameter of the rear end portion 13a of the first inclined portion 13 corresponds to the inner diameter of the inner peripheral surface 35 of the reel seat 30. The rear end portion 13a of the first inclined portion 13 is located radially inside the front end surface 30a of the reel seat 30. Thereby, the first inclined portion 13 is exposed in front of the reel seat 30.

[0029] The first large-diameter portion 14 is a cylindrical rod portion having a large diameter throughout the axial direction, and has an outer diameter corresponding to the inner diameter of the inner peripheral surface 35 of the reel seat 30. The first large-diameter portion 14 is adhered to the inner peripheral surface 35 of the reel seat 30 with an adhesive.

[0030] The rear rod body portion 21 is a cylindrical rod portion having a small diameter throughout the axial direction, and like the front rod body portion 11, has an outer diameter smaller than the inner diameter of the inner peripheral surface 35 of the reel seat 30. The front portion 22 includes a second inclined portion 23 continuous with the front end portion of the rear rod body portion 21, and a second large-diameter portion 24 continuous with the front end portion 23a of the second inclined portion 23. The second inclined portion 23 has a funnel shape (substantially conical shape) that gradually increases in diameter toward the front. The outer diameter of the rear end portion of the second inclined portion 23 corresponds to the outer diameter of the rear rod body portion 21, and the outer diameter of the front end portion 23a of the second inclined portion 23 corresponds to the inner diameter of the inner peripheral surface 35 of the reel seat 30. The front end portion 23a of the second inclined portion 23 is located radially inside the rear end surface 30b of the reel seat 30. Thereby, the second inclined portion 23 is exposed behind the reel seat 30.

[0031] The second large-diameter portion 24 is a cylindrical rod portion having a large diameter over the entire axial direction, and has an outer diameter corresponding to the inner diameter of the inner peripheral surface 35 of the reel sheet 30. The second large-diameter portion 24 is adhered to the inner peripheral surface 35 of the reel sheet 30 with an adhesive. The outer diameter and inner diameter of the second large-diameter portion 24 are the same as the outer diameter and inner diameter of the first large-diameter portion 14. The front end surface 25 of the second large-diameter portion 24 is joined (abutted) to the rear end surface 15 of the first large-diameter portion 14 of the front rod 10, and is adhered to the rear end surface 15 with an adhesive. Thereby, the front rod 10 and the rear rod 20 are integrally connected inside the reel sheet 30.

[0032] The reel sheet 30 is a member for attaching the mounting leg portions of a fishing reel (not shown). Further, the reel sheet 30 functions as a member for fixing the front rod 10 and the rear rod 20, and the front rod 10 and the rear rod 20 are integrally configured via the reel sheet 30. The inner peripheral surface 35 of the reel sheet 30 is a cylindrical surface having a large diameter over the entire axial direction, and has an inner diameter into which the first large-diameter portion 14 of the front rod 10 and the second large-diameter portion 24 of the rear rod 20 are inserted.

[0033] When assembling the fishing rod 1 as described above, the front rod 10 and the rear rod 20 are adhered to the inner peripheral surface 35 of the reel sheet 30 with an adhesive. In this case, an adhesive is applied to the outer peripheral surface of the first large-diameter portion 14 of the front rod 10, the rear end surface 15 of the first large-diameter portion 14, and the inner peripheral surface 35 of the reel sheet 30, and the first large-diameter portion 14 is inserted into the inner peripheral surface 35 from the front of the reel sheet 30 to a predetermined position. Next, an adhesive is applied to the outer peripheral surface of the second large-diameter portion 24 of the rear rod 20 and the front end surface 25 of the second large-diameter portion 24, and the second large-diameter portion 24 is inserted into the inner peripheral surface 35 from the rear of the reel sheet 30. Then, the front end surface 25 of the second neck-resistant portion is abutted against the rear end surface 15 of the first large-diameter portion 14. Thereby, the fishing rod 1 in which the front rod 10 and the rear rod 20 are respectively adhered to the reel sheet 30 with an adhesive is assembled.

[0034] Note that the assembly procedure is not limited to this. The fishing rod 1 may be assembled by a procedure in which the front rod 10 and the rear rod 20 are pre-joined and then inserted into the inner peripheral surface 35 of the reel sheet 30. Note that the joining position (contact position) between the front rod 10 and the rear rod 20 is not limited to the central portion in the axial direction of the inner peripheral surface 35, and may be set by shifting to other positions in the axial direction.

[0035] According to the fishing rod 1 of the present embodiment described above, a part of the rear portion 12 of the front rod 10 and a part of the front portion 22 of the rear rod 20 can be directly adhered to the inner peripheral surface 35 of the reel sheet 30. Therefore, it is not necessary to interpose a spacer for fixing the front rod 10 and the rear rod 20, and the number of parts can be reduced and the weight can be reduced. In addition, since the adhesion process related to the adhesion of the spacer can be eliminated, the assembly time can be shortened and the cost can be reduced.

[0036] Further, when vibration is input to the front rod 10 due to a fish hitting or a fish being hooked, the vibration is directly transmitted from the front rod 10 and the rear rod 20 to the reel sheet 30. Therefore, the vibration is easily transmitted to the hand holding the reel sheet 30, and the sensitivity during actual fishing is good.

[0037] In addition, since the rear portion 12 of the front rod 10 and the front portion 22 of the rear rod 20 are joined together inside the reel sheet 30, the strength of the fishing rod 1 can be improved.

[0038] (Second Embodiment) Next, the fishing rod 1A of the second embodiment will be described with reference to FIG. 2. FIG. 2 is a cross-sectional view showing a main part of the fishing rod 1A according to the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the rear portion 12 of the front rod 10A and the front portion 22 of the rear rod 20A are joined (contacted) corresponding to the clamping region L1 where the mounting leg portion 50 of the fishing reel is clamped.

[0039] As shown in Fig. 2, the first large-diameter portion 14 of the front rod 10A has a shape that is longer in the axial direction compared to that of the first embodiment. On the other hand, the second inclined portion 23 of the rear rod 20A is set to have a larger inclination angle compared to that of the first embodiment. Further, the second large-diameter portion 24 of the rear rod 20A has a shape that is shorter in the axial direction compared to that of the first embodiment.

[0040] The reel seat 30 includes a fixed hood 31 and a floating hood 32. A mounting surface 33 on which the mounting leg portion 50 of the fishing reel is placed is formed between the fixed hood 31 and the floating hood 32. The mounting leg portion 50 is mounted on the mounting surface 33 and is sandwiched between the fixed hood 31 and the floating hood 32 and attached to the reel seat 30. The sandwiching region L1 is a region defined by the fixed hood 31 and the floating hood 32. Such a sandwiching region L1 is substantially reinforced by the mounting of the mounting leg portion 50.

[0041] In the present embodiment, at a position corresponding to the sandwiching region L1 of the mounting leg portion 50, the rear portion 12 of the front rod 10A and the front portion 22 of the rear rod 20A are joined (abutted). That is, a joining position is set within the sandwiching region L1.

[0042] According to the present embodiment, since the joining portion between the rear portion 12 of the front rod 10 and the front portion 22 of the rear rod 20 can be reinforced by the mounting leg portion 50, the strength of the fishing rod 1A can be improved.

[0043] (Third Embodiment) Next, the fishing rod 1B of the third embodiment will be described with reference to Fig. 3. Fig. 3 is a cross-sectional view showing a main part of the fishing rod 1B according to the third embodiment of the present invention. The difference between the present embodiment and the first and second embodiments is that an inlay joint structure is adopted as the joint structure.

[0044] As shown in Fig. 3, an annular member 40 for inlay joint is pre-bonded to the inner surface of the rear end portion 14a of the first large-diameter portion 14 with an adhesive. The front end portion 24a of the second large-diameter portion 24 is externally fitted to the outer rear surface of the annular member 40 and is bonded with an adhesive. With such an inlay joint structure, the rear portion 12 of the front rod 10B and the front portion 22 of the rear rod 20B are joined together. Note that the annular member 40 may be configured to be pre-bonded to the inner surface of the front end portion 24a of the second large-diameter portion 24 with an adhesive. In this case, the rear end portion 14a of the first large-diameter portion 14 is externally fitted to the outer front surface of the annular member 40 and is bonded with an adhesive.

[0045] According to the present embodiment, since the rear portion 12 of the front rod 10B and the front portion 22 of the rear rod 20B can be directly joined by an inlay joint structure inside the reel seat 30, the strength of the fishing rod 1B can be improved. Further, since vibration is preferably transmitted from the front rod 10B to the rear rod 20B by the inlay joint structure, vibration is transmitted to the reel seat 30 from both the front rod 10B and the rear rod 20B. Therefore, the sensitivity during actual fishing is good.

[0046] (Fourth Embodiment) Next, the fishing rod 1C of the fourth embodiment will be described with reference to Fig. 4. Fig. 4 is a cross-sectional view showing the main part of the fishing rod 1C according to the fourth embodiment of the present invention. The difference between the present embodiment and the first to third embodiments is that a butt joint structure is adopted as the joining structure.

[0047] As shown in Fig. 4, the rear end portion 14a of the first large-diameter portion 14 is formed in a stepped cylindrical shape with a reduced diameter so as to have a butt joint structure. The front end portion 24a of the second large-diameter portion 24 is externally fitted to the rear end portion 14a of the first large-diameter portion 14 and is bonded with an adhesive. With such a butt joint structure, the rear portion 12 of the front rod 10C and the front portion 22 of the rear rod 20C are joined together. Note that the splicing structure is not limited to this. The front end portion 24a of the second large-diameter portion 24 may be formed into a stepped cylindrical shape whose diameter is reduced so as to have a butt joint structure, and the rear end portion 14a of the first large-diameter portion 14 may be externally fitted and adhered to the front end portion 24a of the second large-diameter portion 24.

[0048] Also in this embodiment, since the rear portion 12 of the front rod 10C and the front portion 22 of the rear rod 20C can be directly joined by a butt joint structure inside the reel seat 30, the strength of the fishing rod 1C can be improved. Further, since vibration is preferably transmitted from the front rod 10C to the rear rod 20C by the butt joint structure, vibration is transmitted to the reel seat 30 from both the front rod 10C and the rear rod 20C. Therefore, the sensitivity during actual fishing is good.

[0049] (Fifth Embodiment) Next, the fishing rod 1D of the fifth embodiment will be described with reference to FIG. 5. FIG. 5 is a cross-sectional view showing a main part of the fishing rod 1D according to the fifth embodiment of the present invention. The difference between this embodiment and the first to fourth embodiments is that a projection 36 for splicing is provided on the inner peripheral surface 35 of the reel seat 30D.

[0050] As shown in FIG. 5, the projection 36 projects circumferentially from the inner peripheral surface 35 of the reel seat 30D toward the radially inner side. The rear end surface 15 of the first large-diameter portion 14 of the front rod 10D is abutted against the front surface of the projection 36 and adhered with an adhesive. Further, the front end surface 25 of the second large-diameter portion 24 of the rear rod 20D is abutted against the rear surface of the projection 36 and adhered with an adhesive. The front surface and the rear surface of the projection 36 have sizes that face the rear end surface 15 of the front rod 10D and the front end surface 25 of the rear rod 20D, respectively.

[0051] Note that although the protruding portion 36 is shown as protruding circumferentially on the inner peripheral surface 35, it is not limited to this, and it may partially protrude on the inner peripheral surface 35. Further, the protruding height (the amount of protrusion radially inward) of the protruding portion 36 can be set as appropriate. Further, the shape of the protruding portion 36 may be formed into a wall shape that radially partitions the inner peripheral surface 35, and the rear end surface 15 of the front rod 10D and the front end surface 25 of the rear rod 20D may be brought into contact with the front surface and the rear surface thereof.

[0052] According to the present embodiment, the same operational effects as those of the above-described embodiment can be obtained, and at the time of assembling the fishing rod 1D, the positioning of the rear portion 12 of the front rod 10D and the front portion 22 of the rear rod 20D with respect to the inner peripheral surface 35 is easy. Therefore, the assembly time can be shortened, and cost reduction and productivity improvement can be achieved.

[0053] (Sixth Embodiment) Next, the fishing rod 1D1 of the sixth embodiment will be described with reference to FIG. 6. FIG. 6 is a cross-sectional view showing a main part of the fishing rod 1D1 according to the sixth embodiment of the present invention. This embodiment is a modification of the fifth embodiment, and the difference lies in that a butting projection 36D1 is provided on the inner peripheral surface 35 of the reel seat 30D1, and the front end surface 25a of the second large-diameter portion 24 is butted (abutted) against the rear end surface 15 of the first large-diameter portion 14 of the front rod 10.

[0054] As shown in FIG. 6, the protruding portion 36D1 protrudes circumferentially radially inward from the inner peripheral surface 35 of the reel seat 30D1. The protruding portion 36D1 is formed to have a smaller protruding height (the amount of protrusion radially inward) than the protruding portion 36 (see FIG. 5) of the fifth embodiment. A part of the rear end surface 15 of the first large-diameter portion 14 of the front rod 10D1 is abutted against the front surface of the protruding portion 36D1 and adhered with an adhesive. Further, the second front end surface 25b, which will be described later, of the second large-diameter portion 24 of the rear rod 20D1 is abutted against the rear surface of the protruding portion 36D1 and adhered with an adhesive.

[0055] The front end portion 24a of the second large-diameter portion 24 of the rear rod 20D1 is formed in a stepped cylindrical shape with a reduced diameter so as to abut against the rear end face 15 of the first large-diameter portion 14 of the front rod 10. The front end portion 24a includes a first front end face 25a, a second front end face 25b, and a reduced-diameter outer peripheral face 25c. The first front end face 25a is abutted against a part of the rear end face 15 of the first large-diameter portion 14 and is adhered by an adhesive. The second front end face 25b is abutted against the rear face of the protrusion 36D1 and is adhered by an adhesive. Further, the reduced-diameter outer peripheral face 25c is abutted against the inner peripheral face of the protrusion 36D1 and is adhered by an adhesive. That is, the front end portion 24a of the second large-diameter portion 24 extends forward so as to cover the protrusion 36D1 from the inner peripheral face side and is joined to a part of the rear end face 15 of the first large-diameter portion 14. Thereby, the front end portion 24a of the second large-diameter portion 24 is adhered to both the protrusion 36D1 and the rear end face 15 of the first large-diameter portion 14.

[0056] In addition, in the present embodiment, although the front end portion 24a of the second large-diameter portion 24 of the rear rod 20D1 is shown as being formed in a stepped cylindrical shape, the present invention is not limited thereto, and the rear end portion 14a of the front rod 10D1 may be reduced in diameter and formed in a stepped cylindrical shape. In this case, the rear end portion 14a of the first large-diameter portion 14 extends rearward so as to cover the protrusion 36D1 from the inner peripheral face side and is abutted against a part of the front end face 25 (see FIG. 5) of the second large-diameter portion 24 and is adhered by an adhesive.

[0057] According to the present embodiment, the same operational effects as those of the above-described embodiment can be obtained, and at the time of assembling the fishing rod 1D1, the positioning of the rear portion 12 of the front rod 10D1 and the front portion 22 of the rear rod 20D1 with respect to the inner peripheral face 35 is easy. Therefore, the assembly time can be shortened, and cost reduction and productivity improvement can be achieved.

[0058] Further, since the rear portion 12 of the front rod 10D1 and the front portion 22 of the rear rod 20D1 are joined inside the reel seat 30D1, the strength of the fishing rod 1D1 can be improved.

[0059] (Seventh Embodiment) Next, the fishing rod 1E of the seventh embodiment will be described with reference to FIG. 7. FIG. 7 is a cross-sectional view showing a main part of the fishing rod 1E according to the seventh embodiment of the present invention. The difference between this embodiment and the first to sixth embodiments is that the outer diameter of the rear portion 12 of the front rod 10E and the outer diameter of the front portion 22 of the rear rod 20E are made different from each other.

[0060] As shown in FIG. 7, the rear portion 12 of the front rod 10E has a larger diameter overall than the front portion 22 of the rear rod 20E. Relatively, the front portion 22 of the rear rod 20E has a smaller diameter overall than the rear portion 12 of the front rod 10E. Further, correspondingly, the inner peripheral surface 35 of the reel seat 30E is formed as a stepped cylindrical shape having a large-diameter inner peripheral surface 35a and a small-diameter inner peripheral surface 35b with different inner diameters. And a stepped surface 35c is formed at the boundary portion between the large-diameter inner peripheral surface 35a and the small-diameter inner peripheral surface 35b.

[0061] The first large-diameter portion 14 of the front rod 10E is adhered to the large-diameter inner peripheral surface 35a with an adhesive. The rear end surface 15 of the first large-diameter portion 14 is adhered in a state where a part thereof abuts against the stepped surface 35c of the inner peripheral surface 35. The second large-diameter portion 24 of the rear rod 20E is adhered to the small-diameter inner peripheral surface 35b with an adhesive. The front end surface 25 of the second large-diameter portion 24 is adhered in a state where a part thereof abuts against the rear end surface 15 of the first large-diameter portion 14.

[0062] According to this embodiment, the same operational effects as those of the above-described embodiments can be obtained. At the time of assembling the fishing rod 1E, the rear end surface 15 of the first large-diameter portion 14 can be adhered by abutting it against the stepped surface 35c, and the front end surface 25 of the second large-diameter portion 24 can be adhered by abutting it against the rear end surface 15 of the first large-diameter portion 14. Therefore, these assembling operations are easy to perform. Thereby, the assembling time can be shortened, and cost reduction and productivity improvement can be achieved.

[0063] In addition, the structure in which the rear portion 12 of the front rod 10E and the front portion 22 of the rear rod 20E are directly adhered to the inner peripheral surface 35 of the reel sheet 30 can be varied, and the appearance of the exposed portion can also be changed. Thereby, the fishing rod 1E can be configured according to the fishing type.

[0064] (Eighth Embodiment) Next, the fishing rod 1F of the eighth embodiment will be described with reference to FIG. 8. FIG. 8 is a cross-sectional view showing a main part of the fishing rod 1F according to the eighth embodiment of the present invention. This embodiment is a modified example combining the fifth embodiment and the seventh embodiment. The difference is that the outer diameter of the rear portion 12 of the front rod 10F and the outer diameter of the front portion 22 of the rear rod 20F are made different from each other, and the rear portion 12 of the front rod 10F and the front portion 22 of the rear rod 20F are brought into contact (applied) with the protrusion 36F provided on the inner peripheral surface 35.

[0065] As shown in FIG. 8, the rear portion 12 of the front rod 10F is generally larger in diameter as a whole than the front portion 22 of the rear rod 20F. Relatively, the front portion 22 of the rear rod 20F is generally smaller in diameter as a whole than the rear portion 12 of the front rod 10F. Correspondingly, the inner peripheral surface 35 of the reel sheet 30F is provided with a large-diameter inner peripheral surface 35a and a small-diameter inner peripheral surface 35b having different inner diameters. The inner peripheral surface 35 has a stepped cylindrical shape.

[0066] The protrusion 36F protrudes circumferentially inward in the radial direction at the boundary between the large-diameter inner peripheral surface 35a and the small-diameter inner peripheral surface 35b. The rear end surface 15 of the first large-diameter portion 14 of the front rod 10F is in contact with the front surface of the protrusion 36 and is adhered by an adhesive. Also, the front end surface 25 of the second large-diameter portion 24 of the rear rod 20F is in contact with the rear surface of the protrusion 36 and is adhered by an adhesive.

[0067] According to this embodiment, the same operational effects as those of the above-described fifth and seventh embodiments can be obtained. That is, at the time of assembling the fishing rod 1F, the positioning of the rear portion 12 of the front rod 10F and the front portion 22 of the rear rod 20F can be easily performed. Therefore, the assembly time can be shortened, and cost reduction and productivity improvement can be achieved. In addition, variations can be provided in the structure in which the rear portion 12 of the front rod 10F and the front portion 22 of the rear rod 20F are directly adhered to the inner peripheral surface 35 of the reel seat 30, and the appearance of the exposed portion can also be changed. Thereby, the fishing rod 1F can be made according to the fishing type.

[0068] (Ninth Embodiment) Next, the fishing rod 1G of the ninth embodiment will be described with reference to FIG. 9. FIG. 9 is a cross-sectional view showing the front rod 10G of the fishing rod 1G according to the ninth embodiment of the present invention. The difference between this embodiment and the first to eighth embodiments is that the thickness of the rear portion 12 of the front rod 10G is formed to be thinner toward the rear end portion 14a (insertion end).

[0069] As shown in FIG. 9, the first inclined portion 13 of the rear portion 12 in the front rod 10G is formed such that the thickness gradually decreases from the front side to the rear side. Along with this, the first large-diameter portion 14 continuous with the first inclined portion 13 also has a thinner thickness compared to those in the above embodiments. Although the first large-diameter portion 14 is shown as being formed with substantially the same thickness over the entire axial direction, it is not limited thereto, and it may be formed such that the thickness further decreases toward the rear end portion 14a.

[0070] Also in this embodiment, since the first large-diameter portion 14 (rear portion 12) of the front rod 10G is directly adhered to the inner peripheral surface 35 (see FIG. 1 etc.) of the reel seat 30, a predetermined strength can be ensured. Moreover, weight reduction of the fishing rod 1G can be realized by the thin-wall structure. Note that, similarly to the front rod 10G, the second inclined portion 23 of the front portion 22 of the rear rod 20G (not shown) may be formed such that the thickness gradually decreases from the rear side to the front side. Alternatively, only the rear rod 20G may be formed to have a thinner thickness.

[0071] (Embodiment 10) Next, the fishing rod 1H of the 10th embodiment will be described with reference to FIG. 10. FIG. 10 is a cross-sectional view showing the main part of the fishing rod 1H according to the 10th embodiment of the present invention. The difference between this embodiment and the above-described 1st to 9th embodiments is that the rear part 12 of the front rod 10H and the front part 22 of the rear rod 20H are arranged with a space S1 in the axial direction of the reel seat 30.

[0072] As shown in FIG. 10, the rear end face 15 of the first large-diameter part 14 of the front rod 10H and the front end face 25 of the second large-diameter part 24 of the rear rod 20H face each other with a space S1 inside the reel seat 30 and are arranged in a non-contact state. Note that the size of the space S1 can be set as appropriate.

[0073] According to this embodiment, the same operational effects as those of the above-described embodiments can be obtained, and since it is not necessary to join the rear part 12 of the front rod 10H and the front part 22 of the rear rod 20H inside the reel seat 30, the adhesive is unnecessary accordingly. Thereby, cost reduction can be achieved.

[0074] (Embodiment 11) Next, the fishing rod 1J of the 11th embodiment will be described with reference to FIG. 11. FIG. 11 is a cross-sectional view showing the main part of the fishing rod 1J according to the 11th embodiment of the present invention. The difference between this embodiment and the above-described 1st to 10th embodiments is that the first large-diameter part 14 of the front rod 10H and the second large-diameter part 24 of the rear rod 20H are provided so as to be exposed before and after the reel seat 30.

[0075] As shown in FIG. 11, the first large-diameter part 14 of the front rod 10H extends in front of the front end face 30a of the reel seat 30, and a part thereof is exposed in front of (outside) the reel seat 30. Thereby, the rear end part 13a of the first inclined part 13 is also located in front of the front end face 30a of the reel seat 30.

[0076] Similarly, the second large-diameter portion 24 of the rear rod 20H extends behind the rear end face 30b of the reel seat 30, and a part thereof is exposed behind (outside) the reel seat 30. Accordingly, the front end portion 23a of the second inclined portion 23 is also located behind the rear end face 30b of the reel seat 30.

[0077] Note that either one of the first large-diameter portion 14 of the front rod 10H and the second large-diameter portion 24 of the rear rod 20H may be configured to be exposed outside the reel seat 30.

[0078] According to the present embodiment, variations can be provided to the structure in which the rear portion 12 of the front rod 10J and the front portion 22 of the rear rod 20J are directly adhered to the inner peripheral surface 35 of the reel seat 30, and the appearance of the exposed portion can be changed. Thereby, the fishing rod 1J can be configured according to the type of fishing.

[0079] Although the embodiments of the present invention have been described above, design changes can be appropriately made without departing from the spirit of the present invention. For example, in each of the above embodiments, the first inclined portion 13 and the second inclined portion 23 are shown as being provided so as to be exposed outside the reel seat 30, but the present invention is not limited thereto, and a part thereof may be configured to be disposed inside the inner peripheral surface 35 of the reel seat 30.

[0080] Further, for example, a hole may be formed in the reel seat 30 (30D, etc.) so that the joining state (contact state) between the rear portion 12 of the front rod 10 (10A, etc.) and the front portion 22 of the rear rod 20 (20A, etc.) can be visually recognized from the outside.

[0081] Also, in each of the above embodiments, the front rod 10 (10A, etc.) and the rear rod 20 (20A, etc.) configured as tubular bodies (hollow bodies) are shown, but the present invention is not limited thereto, and one or both of the front rod 10 (10A, etc.) and the rear rod 20 (20A, etc.) may be configured as solid bodies.

[0082] Also, the rear portion 12 of the front rod 10 (such as 10A) may be formed of a fiber-reinforced resin prepreg (prepreg sheet) different from the front rod main body portion 11. Similarly, the front portion 22 of the rear rod 20 (such as 20A) may be formed of a fiber-reinforced resin prepreg (prepreg sheet) different from the rear rod main body portion 21.
