Description

[Technical field]

[0001] The present invention relates to a fishing rod spacer for mounting a reel seat or a grip to a fishing rod, a reel seat, and a grip. [Background technology]

[0002] Conventionally, when attaching a reel seat or grip to the rod shaft of a fishing rod, a circumferentially wound string, a sealing material, or a cylindrical spacer is interposed as a gap member to fill the gap between the inner peripheral surface of the reel seat or grip and the outer peripheral surface of the rod. Usually, a gap of about φ0.1 to 0.2 mm is provided between the inner peripheral surface of the reel seat or the like and the gap member to prevent radial positional deviation (center deviation) relative to the rod and to introduce adhesive.

[0003] However, because the size of the gap is extremely small, there is a risk that the adhesive applied to the surface of the gap member will be squeezed out at the entrance of the reel seat, etc., when inserting the rod inside the reel seat, etc., making it difficult to introduce the adhesive inside the reel seat, etc.

[0004] In this regard, a technology that takes into consideration the introduction of adhesive is disclosed in Patent Document 1. In Patent Document 1, a slit space penetrating from the inner surface to the outer surface of the spacer member is provided, and adhesive is introduced from the inner surface side to the outer surface side of the spacer member through this slit space. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2001-333668 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, since Patent Document 1 has a structure in which adhesive is introduced from the inner surface side to the outer surface side of the spacer member through the slit space, an unnecessary adhesive layer is generated in the slit space, which leads to an increase in weight.

[0007] The present invention was created to solve such problems, and its objective is to provide a fishing rod spacer, reel seat, and grip that are less likely to become misaligned with the rod shaft, allow sufficient adhesive to be applied to the bonding surface, and are lightweight. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a fishing rod spacer for attaching a mounting member to a rod shaft of a fishing rod. The fishing rod spacer has a cylindrical shape and includes a spacer body extending in the axial direction of the rod shaft, and a spacer body formed on at least one of an inner peripheral surface and an outer peripheral surface of the spacer body, and a mounting member extending in the axial direction of the rod shaft. Throughout and a groove portion extending in the axial direction of the spacer body. both ends It is open at one end Opening From the other end Opening The groove width in the circumferential direction is narrowed toward the end, and / or the groove depth in the radial direction is Opening From the other end Opening It is shallowly formed towards the

[0009] In this fishing rod spacer, the groove width in the circumferential direction and / or the groove depth in the radial direction of the groove is different between one end side and the other end side of the spacer body, so that when a rod or a mounting member is attached to the spacer body from one end side, the adhesive applied to the bonding surface enters the groove and is appropriately guided from the one end side to the other end side. Therefore, sufficient adhesive can be introduced to the bonding surface. Also, since the amount of adhesive is kept appropriate, the weight can be reduced compared to conventional ones that have unnecessary adhesive layers. In addition, since sufficient adhesive can be introduced to the bonding surface, the size of the gap between the inner circumferential surface of the spacer body and the outer circumferential surface of the rod, and the size of the gap between the outer circumferential surface of the spacer body and the inner circumferential surface of the workpiece can be set to be extremely small, which makes it difficult for the workpiece to become misaligned with the rod.

[0010] The fishing rod spacer according to the present invention is for attaching a mounting member to a rod shaft of a fishing rod. The fishing rod spacer includes a cylindrical spacer body extending in the axial direction of the rod shaft, and grooves formed on both the inner and outer circumferential surfaces of the spacer body and extending in the axial direction. The grooves on the inner circumferential surface open to one end in the axial direction of the spacer body, and the circumferential groove width is narrowed from one end to the other end, and / or the radial groove depth is shallowed from one end to the other end. The grooves on the outer circumferential surface open to the other end in the axial direction of the spacer body, and the circumferential groove width is narrowed from the other end to the one end, and the radial groove depth is shallowed from the other end to the one end.

[0011] This fishing rod spacer has the same effect as the fishing rod spacer of the above-mentioned invention. In addition, the directionality of the groove width and the groove depth differs between the inner and outer peripheral surfaces. This makes it possible to adopt an attachment method in which, for example, the rod is attached to the inner peripheral surface from one end of the spacer body, and the attached member is attached to the outer peripheral surface from the other end of the spacer body. This has the advantage of expanding the variety of attachment operations.

[0012] It is also preferable that a plurality of the grooves are formed in the circumferential direction of the spacer body. By adopting this configuration, the joining strength between the rod and the spacer body and the joining strength between the attached member and the spacer body are increased.

[0013] The reel seat according to the present invention is for mounting a fishing reel on a rod shaft of a fishing rod. The reel seat has a cylindrical inner peripheral surface and includes a reel seat body extending in the axial direction of the rod shaft, and a reel seat member formed on the inner peripheral surface and extending in the axial direction of the rod shaft. Throughout The groove portion extends in the axial direction of the reel seat body. both ends It is open at one end Opening From the other end Opening The groove width in the circumferential direction is narrowed toward the end, and / or the groove depth in the radial direction is Opening From the other end Opening It is shallowly formed towards the

[0014] In this reel seat, the groove width in the circumferential direction and / or the groove depth in the radial direction of the groove differs between one end side and the other end side of the reel seat body, so that when the rod is attached to the reel seat body from one end side, the adhesive applied to the adhesive surface enters the groove and is appropriately guided from the one end side to the other end side. Therefore, sufficient adhesive can be introduced to the adhesive surface. Also, because the amount of adhesive is kept appropriate, the weight can be reduced compared to conventional reels that have unnecessary adhesive layers. In addition, since a sufficient amount of adhesive can be applied to the adhesive surface, the size of the gap between the inner peripheral surface of the reel seat body and the outer peripheral surface of the rod can be set to be extremely small, which makes it difficult for the rod to become misaligned.

[0015] The grip according to the present invention is attached to a rod shaft of a fishing rod. The grip comprises a grip body having a cylindrical inner peripheral surface and extending in the axial direction of the rod shaft, and a grip portion formed on the inner peripheral surface and extending in the axial direction of the rod shaft. Throughout The grip body has a groove extending in the axial direction. both ends It is open at one end Opening From the other end Opening The groove width in the circumferential direction is narrowed toward the end, and / or the groove depth in the radial direction is Opening From the other end Opening It is shallowly formed towards the

[0016] In this grip, the groove width in the circumferential direction and / or the groove depth in the radial direction of the groove differs between one end and the other end of the grip body, so that when the rod is attached to the grip body from one end, the adhesive applied to the adhesive surface enters the groove and is appropriately guided from the one end to the other end. Therefore, sufficient adhesive can be introduced to the adhesive surface. Also, since the amount of adhesive is kept at an appropriate amount, the grip can be made lighter than conventional grips that have unnecessary adhesive layers. In addition, since a sufficient amount of adhesive can be applied to the adhesive surface, the size of the gap between the inner peripheral surface of the grip body and the outer peripheral surface of the rod can be set to be extremely small, which makes it difficult for the grip body to become misaligned with the rod. Effect of the Invention

[0017] The fishing rod spacer, reel seat and grip according to the present invention are less likely to become misaligned with the rod shaft, allow sufficient adhesive to be applied to the bonding surface, and achieve weight reduction. [Brief description of the drawings]

[0019] Hereinafter, the fishing rod spacer, reel seat, and grip according to the embodiment of the present invention will be described with reference to the drawings. First, the fishing rod spacer according to the embodiment of the present invention will be described. In the description of the embodiment, the terms "left and right" refer to the directions shown in FIG. 1.

[0020] (First embodiment) As shown in Fig. 1(a), the fishing rod spacer S has a cylindrical shape. The fishing rod spacer S is used when attaching a reel seat, a grip, or other attachment member to a rod shaft of a fishing rod (not shown), and is interposed between the rod shaft and the reel seat.

[0021] The fishing rod spacer S is integrally formed from resin. Examples of resin include ABS resin, ASA resin, PLA resin, PP resin, PET resin, epoxy resin, acrylic resin, polycarbonate resin, polyamide resin, and resins containing carbon fibers. When resin is used, the fishing rod spacer S can be easily manufactured using a 3D printer or the like. In addition, metals and gypsum may be used as materials other than resin. Examples of metals include iron, copper, nickel, titanium, stainless steel, and aluminum.

[0022] The fishing rod spacer S includes a spacer body 1, a groove 10 formed on the inner peripheral surface of the spacer body 1, and a groove 20 (see FIG. 1(b)) formed on the outer peripheral surface of the spacer body 1. The inner peripheral surface of the spacer body 1 has an inner diameter slightly larger than the outer diameter of a rod 50 (see FIG. 3(b)(c)) of a fishing rod, and is sized to form a gap of about φ0.1 to 0.2 mm between the inner peripheral surface of the rod 50. The outer peripheral surface of the spacer body 1 has an outer diameter slightly smaller than the inner diameter of a mounting member 60 such as a reel seat (see FIG. 3(a)(c)), and is sized to form a gap of about φ0.1 to 0.2 mm between the inner peripheral surface of the mounting member 60.

[0023] The grooves 10 on the inner circumferential surface are formed linearly from the left side surface (one end surface) to the right side surface (the other end surface) of the spacer body 1 as shown in Figs. 1(a) and 2(c). A total of six grooves 10 are formed at intervals in the circumferential direction of the inner circumferential surface as shown in Figs. 1(a) and 2(c). Each groove 10 opens on the left side surface and the right side surface as shown in Figs. 2(c) and (d). Each groove 10 is formed so that the groove width (size) in the circumferential direction narrows from the left side surface to the right side surface as shown in Figs. 2(a) and (b). Specifically, the grooves 10 are formed in a tapered shape so that the groove width of the grooves 10 becomes gradually narrower from the left side surface to the right side surface as viewed in the radial direction of the spacer body 1. The groove depth of the groove portion 10 is constant. The groove portions 10 do not have to be spaced evenly, but in this embodiment, they are disposed at equal intervals in the circumferential direction.

[0024] A plurality of these grooves 10 are formed on the inner peripheral surface of the spacer body 1, and protrusions 11 are formed relatively between the grooves 10. A left edge 15 of each protrusion 11 is chamfered into an inclined or curved surface. In this embodiment, a right edge of each protrusion 11 is also chamfered into an inclined or curved surface.

[0025] As shown in Figures 2(c) and 2(d), the grooves 20 on the outer peripheral surface are formed at positions radially corresponding to the grooves 10 on the inner peripheral surface. Each groove 20 on the outer peripheral surface has the same configuration as each groove 10 on the inner peripheral surface. Specifically, as shown in Fig. 1(a)(b) and Fig. 2(b)-(d), each groove 20 on the outer circumferential surface is formed in a straight line from the left side surface (one end surface) to the right side surface (the other end surface) of the spacer body 1. As shown in Fig. 1(a) and Fig. 2(c)(d), a total of six grooves 20 are formed at intervals in the circumferential direction of the outer circumferential surface. As shown in Fig. 2(c)(d), each groove 20 opens on the left side surface and the right side surface, respectively. As shown in Fig. 2(a)(b), each groove 20 is formed so that the groove width (size) in the circumferential direction becomes narrower from the left side surface to the right side surface. Specifically, as seen in the radial direction of the spacer body 1, the groove width of the groove 20 is formed in a tapered shape so that it gradually becomes narrower from the left side surface to the right side surface. The groove depth of the groove portion 20 is constant. The groove portions 20 do not have to be spaced evenly, but in this embodiment, they are disposed at equal intervals in the circumferential direction.

[0026] A plurality of these grooves 20 are formed on the outer circumferential surface of the spacer body 1, and protrusions 21 are formed relatively between the grooves 20. A left edge 25 of each protrusion 21 is chamfered into an inclined or curved surface. In this embodiment, a right edge of each protrusion 21 is also chamfered into an inclined or curved surface.

[0027] Next, the operation of attaching the attachment member 60 to the rod shaft 50 of the fishing rod using the fishing rod spacer S will be described with reference to each of FIGS. First, as shown in Fig. 3(a), the attachment member 60 is attached to the outer circumferential surface of the fishing rod spacer S. In this case, adhesive for fixing is applied to the entire outer circumferential surface of the spacer body 1, and adhesive is also applied to the entire inner circumferential surface 61 of the attachment member 60. Then, the attachment member 60 is brought close to the left side, which is the side with the larger groove width of the groove portion 20 on the outer circumferential surface of the spacer body 1, and the attachment member 60 is placed over the outer circumferential surface of the spacer body 1.

[0028] Then, each of the protrusions 21 on the outer peripheral surface of the spacer body 1 abuts against the inner peripheral surface 61 of the workpiece 60 or faces it with a small gap, and the adhesive applied to the inner peripheral surface 61 of the workpiece 60 is pushed aside toward each of the grooves 20 by the left edge 25 of each of the protrusions 21. This allows the adhesive to be suitably guided into the grooves 20. Here, each of the grooves 20 is formed so that the groove width gradually narrows from the left side surface to the right side surface, and the cross-sectional area becomes smaller toward the right side surface. As a result, in the process of covering the workpiece 60 on the outer peripheral surface of the spacer body 1, the adhesive that has entered each of the grooves 20 is guided toward the right side surface at the end while filling the groove. Therefore, sufficient adhesive can be introduced into the grooves 20, which will be the adhesive surface. After that, the workpiece 60 is covered up to a predetermined position on the outer peripheral surface of the spacer body 1.

[0029] Then, the rod shaft 50 of the fishing rod is inserted into the inner peripheral surface of the fishing rod spacer S. In this case, adhesive is applied to the entire inner peripheral surface of the spacer body 1, and adhesive is also applied to the entire outer peripheral surface of the rod 50. Then, the rod 50 is brought close to the left side, which is the side with the larger groove width of the groove portion 10 on the inner peripheral surface of the spacer body 1, and the rod 50 is inserted into the inner peripheral surface of the spacer body 1.

[0030] Then, each of the protrusions 11 on the inner peripheral surface of the spacer body 1 abuts against the outer peripheral surface 51 of the rod 50 or faces each other with a small gap, and the adhesive applied to the outer peripheral surface of the rod 50 is pushed aside toward each of the grooves 10 by the left edge 15 of each of the protrusions 11. This allows the adhesive to be suitably guided into each of the grooves 10. Here, each of the grooves 10 is formed so that the groove width gradually narrows from the left side surface to the right side surface, and the cross-sectional area changes so as to become smaller toward the right side surface. As a result, during the process of inserting the rod 50 into the inner peripheral surface of the spacer body 1, the adhesive that has entered each of the grooves 10 is guided toward the right side surface at the end while filling the groove. Therefore, sufficient adhesive can be introduced into each of the grooves 10, which will be the adhesive surface. After that, the rod 50 is inserted to a predetermined position to complete the installation. As a result, the attached member 60 can be attached to the rod 50 using the fishing rod spacer S, as shown in FIG. 3(c).

[0031] According to the fishing rod spacer S of the present embodiment described above, the groove widths of the grooves 10, 20 in the circumferential direction are different between the left side surface side and the right side surface side of the spacer body 1. Therefore, when the rod 50 or the mounting member 60 is attached to the spacer body 1 from the left side surface (one end side), the adhesive applied to the bonding surface enters the grooves 10, 20, and the adhesive that has entered the grooves 10, 20 is suitably guided from the left side surface side to the right side surface side. Therefore, sufficient adhesive can be introduced to the bonding surface. In addition, since the amount of adhesive is kept at an appropriate amount, it is possible to achieve weight reduction compared to a conventional one having an unnecessary adhesive layer. In addition, since sufficient adhesive can be introduced to the bonding surface, the size of the gap between the inner peripheral surface of the spacer body 1 and the outer peripheral surface of the rod 50 and the size of the gap between the outer peripheral surface of the spacer body 1 and the inner peripheral surface of the member 60 to be attached can be set to be extremely small. Therefore, misalignment of the member 60 to the rod 50 is unlikely to occur.

[0032] In addition, since a plurality of grooves 10, 20 are formed in the circumferential direction of the spacer body 1, the bonding strength between the rod 50 and the spacer body 1 and between the attached member 60 and the spacer body 1 is increased. In addition, since the left edges 15, 25 of the protrusions 11, 21 are chamfered, the adhesive can more easily penetrate into the interior.

[0033] Second embodiment Next, a fishing rod spacer according to a second embodiment will be described with reference to Figures 4 and 5. This embodiment differs from the first embodiment in that a groove portion 10 is provided only on the inner peripheral surface of the spacer body 1A.

[0034] Each groove 10 of the spacer body 1A is similar to that described in the first embodiment. That is, the groove 10 is formed so that the groove width (size) in the circumferential direction narrows from the left side surface to the right side surface. Specifically, the groove 10 is formed in a tapered shape so that the groove width of the groove 10 becomes gradually narrower from the left side surface to the right side surface when viewed in the radial direction of the spacer body 1.

[0035] A mounting member 60 can be attached to the outer peripheral surface of the spacer body 1A, for example, by a conventional method.

[0036] According to this embodiment, the same effect as that of the first embodiment can be obtained with respect to the attachment of the rod 50 to the fishing rod spacer S. That is, since the groove width in the circumferential direction of the groove portion 10 is different between the left side surface side and the right side surface side of the spacer body 1A, when the rod 50 is attached to the spacer body 1A from the left side surface (one end side), the adhesive applied to the adhesive surface enters the groove portion 10, and the adhesive that has entered the groove portion 10 is suitably guided from the left side surface side to the right side surface side. Therefore, a sufficient amount of adhesive can be introduced to the adhesive surface. Also, since the amount of adhesive is kept appropriate, the weight can be reduced compared to that of a conventional rod having an unnecessary adhesive layer. In addition, since a sufficient amount of adhesive can be introduced to the bonding surface, the size of the gap between the inner peripheral surface of the spacer body 1A and the outer peripheral surface of the rod 50 can be set to be extremely small. Therefore, misalignment of the attached member 60 with respect to the rod 50 is unlikely to occur.

[0037] Third embodiment Next, a fishing rod spacer according to a third embodiment will be described with reference to Figures 6 and 7. This embodiment differs from the first embodiment in that a groove 20 is provided only on the outer circumferential surface of the spacer body 1B.

[0038] Each groove 20 of the spacer body 1B is similar to that described in the first embodiment. That is, the groove 20 is formed so that the groove width (size) in the circumferential direction narrows from the left side surface to the right side surface. Specifically, the groove 20 is formed in a tapered shape so that the groove width of the groove 20 gradually narrows from the left side surface to the right side surface when viewed in the radial direction of the spacer body 1B.

[0039] A rod 50 can be attached to the inner peripheral surface of the spacer body 1B, for example, by a conventional method.

[0040] According to this embodiment, the same effect as that of the first embodiment can be obtained with respect to the attachment of the attachment member 60 to the fishing rod spacer S. That is, since the groove width in the circumferential direction of the groove portion 20 is different between the left side surface side and the right side surface side of the spacer body 1B, when the attachment member 60 is attached to the spacer body 1B from the left side surface (one end side), the adhesive applied to the adhesive surface enters the groove portion 20, and the adhesive that has entered the groove portion 20 is suitably guided from the left side surface side to the right side surface side. Therefore, a sufficient amount of adhesive can be introduced to the adhesive surface. Also, since the amount of adhesive is kept at an appropriate amount, it is possible to achieve a weight reduction compared to a conventional one having an unnecessary adhesive layer. In addition, since a sufficient amount of adhesive can be introduced to the bonding surface, the size of the gap between the outer circumferential surface of the spacer body 1B and the outer circumferential surface of the member 60 to be attached can be set extremely small. Therefore, misalignment of the member 60 to the rod 50 is unlikely to occur.

[0041] (Fourth embodiment) Next, a fishing rod spacer according to a fourth embodiment will be described with reference to Figures 8 and 9. This embodiment differs from the first to third embodiments in that the groove depths of the grooves 10C, 20C are different.

[0042] As shown in Figures 8(a) and 8(b), the fishing rod spacer S comprises a spacer body 1C, a groove portion 10C formed on the inner surface of the spacer body 1C, and a groove portion 20C (see Figure 8(b)) formed on the outer surface of the spacer body 1C.

[0043] The grooves 10C on the inner circumferential surface are formed linearly from the left side surface (one end surface) to the right side surface (the other end surface) of the spacer body 1C as shown in Figs. 8(a) and 9(c). A total of six grooves 10C are formed at intervals in the circumferential direction of the inner circumferential surface as shown in Figs. 8(a) and 9(c). Each groove 10C opens on the left side surface and the right side surface as shown in Figs. 9(c) and (d). As shown in Figs. 9(a) and (b), each groove 10C is formed so that the radial groove depth is shallower from the left side surface to the right side surface. Specifically, as viewed from the axial direction of the spacer body 1C, the groove depth of the groove 10C is formed in an inclined manner so that it gradually becomes shallower from the left side surface to the right side surface. Each groove 10C has the same circumferential groove width from the left side surface to the right side surface.

[0044] A plurality of grooves 10C are formed on the inner peripheral surface of the spacer body 1C, and protrusions 11C are formed between adjacent grooves 10C. A left edge 15 of each protrusion 11C is chamfered into an inclined surface. In this embodiment, a right edge of each protrusion 11C is also chamfered into an inclined surface or a curved surface.

[0045] As shown in Figures 9(c) and (d), the grooves 20C on the outer peripheral surface are formed at positions radially corresponding to the grooves 10C on the inner peripheral surface. Each groove 20C on the outer peripheral surface has the same configuration as each groove 10C on the inner peripheral surface. Specifically, as shown in Fig. 8(a)(b) and Fig. 9(b)-(d), each groove 20C on the outer peripheral surface is formed in a straight line from the left side surface (one end surface) to the right side surface (the other end surface) of the spacer body 1C. As shown in Fig. 8(a) and Fig. 9(c)(d), a total of six grooves 20C are formed at intervals in the circumferential direction of the outer peripheral surface. As shown in Fig. 9(c)(d), each groove 20C opens on the left side surface and the right side surface, respectively. As shown in Fig. 9(a)(b), each groove 20C is formed so that the radial groove depth is shallower from the left side surface to the right side surface. Specifically, as seen from the axial direction of the spacer body 1C, the groove depth of the groove 20C is formed in an inclined manner so that it gradually becomes shallower from the left side surface to the right side surface. Note that each groove 20C has the same circumferential groove width from the left side surface to the right side surface.

[0046] The spacer body 1C has an inner peripheral surface on which a plurality of grooves 20C are formed, and protrusions 21C are formed between adjacent grooves 20C. A left edge 25 of each protrusion 21C is chamfered into an inclined or curved surface. In this embodiment, the right edge of each protrusion 21C is also chamfered into an inclined surface.

[0047] Next, the action of attaching the member 60 to the rod 50 of the fishing rod using the fishing rod spacer S will be described. When the member 60 is placed on the outer peripheral surface of the spacer body 1C from the left side, each of the protrusions 21C on the outer peripheral surface of the spacer body 1C comes into contact with the inner peripheral surface of the member 60, and the left edge 25 of each of the protrusions 21C pushes the adhesive applied to the inner peripheral surface of the member 60 toward each of the grooves 20C. This allows the adhesive to be suitably guided into the grooves 20C. Here, each of the grooves 20C is formed in an inclined shape so that the radial groove depth gradually becomes shallower from the left side surface to the right side surface, and the cross-sectional area changes to become smaller toward the right side surface. As a result, during the process of placing the member 60 on the outer peripheral surface of the spacer body 1C, the adhesive that has entered into each of the grooves 20C is guided toward the right side surface at the end while filling the groove. Therefore, sufficient adhesive can be introduced into the grooves 20C, which will be the adhesive surface. Thereafter, the mounting member 60 is placed over the outer circumferential surface of the spacer body 1C up to a predetermined position.

[0048] Then, when the rod 50 is inserted into the inner circumferential surface of the spacer body 1C, each of the projections 11C on the inner circumferential surface of the spacer body 1C comes into contact with the outer circumferential surface of the rod 50, and the adhesive applied to the outer circumferential surface of the rod 50 is pushed aside toward each of the grooves 10C by the left edge 15 of each projection 11C. This allows the adhesive to be suitably guided into each of the grooves 10C. Here, each of the grooves 10C is formed in an inclined shape so that the radial groove depth gradually becomes shallower from the left side surface to the right side surface, and the cross-sectional area changes so as to become smaller toward the right side surface. As a result, during the process of inserting the rod 50 into the inner circumferential surface of the spacer body 1C, the adhesive that has entered each of the grooves 10C is guided toward the right side surface at the end while filling the groove. Therefore, sufficient adhesive can be introduced into each of the grooves 10C, which will be the adhesive surface. Then, the rod 50 is inserted to a predetermined position, and the installation is completed. This allows the mounting member 60 to be mounted on the rod 50 using the fishing rod spacer S.

[0049] According to the fishing rod spacer S of the present embodiment described above, the groove depths in the radial direction of the grooves 10C, 20C are different between the left side surface side and the right side surface side of the spacer body 1C. Therefore, when the rod 50 or the mounting member 60 is attached to the spacer body 1C from the left side surface (one end side), the adhesive applied to the bonding surface enters the grooves 10C, 20C, and the adhesive that has entered the grooves 10C, 20C is suitably guided from the left side surface side to the right side surface side. Therefore, sufficient adhesive can be introduced to the bonding surface. In addition, since the amount of adhesive is kept at an appropriate amount, it is possible to reduce the weight compared to a conventional one having an unnecessary adhesive layer. In addition, since sufficient adhesive can be introduced to the bonding surface, the size of the gap between the inner peripheral surface of the spacer body 1C and the outer peripheral surface of the rod 50 and the size of the gap between the outer peripheral surface of the spacer body 1C and the inner peripheral surface of the attachment member 60 can be set to be extremely small. Therefore, misalignment of the attachment member 60 with respect to the rod 50 is unlikely to occur.

[0050] Next, a reel seat according to an embodiment of the present invention will be described with reference to Fig. 10. Fig. 10 is a cross-sectional view showing the reel seat according to the embodiment. 10, the reel seat 60D has a groove 10 and a protrusion 11 formed on the inner circumferential surface 65 of the reel seat body, similar to those described in the first and second embodiments. Also, the left edge 15 of the protrusion 11 is beveled. In other words, the reel seat 60D has a structure in which the groove 10, which has the same structure as the fishing rod spacer S, is provided directly on the inner circumferential surface 65.

[0051] According to the reel seat 60D of this embodiment, the groove width in the circumferential direction of the groove portion 10 is different between the left side surface side and the right side surface side of the reel seat 60D. Therefore, when the rod 50 is attached to the reel seat 60D from the left side surface (one end side), the adhesive applied to the outer circumferential surface (adhesive surface) of the rod 50 enters the groove portion 10, and the adhesive that has entered the groove portion 10 is suitably guided from the left side surface side to the right side surface side. Therefore, a sufficient amount of adhesive can be introduced to the adhesive surface. Also, since the amount of adhesive is kept appropriate, the weight can be reduced compared to a conventional rod having an unnecessary adhesive layer. In addition, since a sufficient amount of adhesive can be applied to the bonding surface, the size of the gap between the inner peripheral surface of the reel seat 60D and the outer peripheral surface of the rod 50 can be set to be extremely small. Therefore, misalignment of the reel seat 60D with respect to the rod 50 is unlikely to occur.

[0052] Instead of groove portion 10, a groove portion whose depth becomes gradually shallower along the extension direction as shown in the fourth embodiment may be provided on the inner peripheral surface 65, or the groove depth may become gradually shallower along the extension direction in accordance with groove portion 10.

[0053] Next, a grip according to one embodiment of the present invention will be described with reference to Fig. 11. Fig. 11 is a cross-sectional view showing a grip according to one embodiment. As shown in Fig. 11, the grip 60E has a groove 10 and a protrusion 11 formed on an inner circumferential surface 66 of the grip body, similar to those described in the first and second embodiments. Also, the left edge 15 of the protrusion 11 is chamfered into an inclined or curved surface. In other words, the grip 60E has a structure in which the groove 10, which has the same structure as the fishing rod spacer S, is provided directly on the inner circumferential surface 66.

[0054] According to the grip 60E of this embodiment, the groove width in the circumferential direction of the groove portion 10 is different between the left side surface side and the right side surface side of the grip 60E, so that when the rod 50 is attached to the grip 60E from the left side surface (one end side), the adhesive applied to the outer circumferential surface (adhesive surface) of the rod 50 enters the groove portion 10, and the adhesive that has entered the groove portion 10 is suitably guided from the left side surface side to the right side surface side. Therefore, sufficient adhesive can be introduced to the adhesive surface. In addition, since the amount of adhesive is kept at an appropriate amount, it is possible to achieve weight reduction compared to those having an unnecessary adhesive layer as in the past. In addition, since a sufficient amount of adhesive can be introduced to the adhesive surface, the size of the gap between the inner peripheral surface of the grip 60E and the outer peripheral surface of the rod 50 can be set to be extremely small. Therefore, misalignment of the grip 60E with respect to the rod 50 is unlikely to occur.

[0055] In addition, instead of groove portion 10, a groove portion whose depth gradually becomes shallower along the extension direction as shown in the fourth embodiment may be provided on the inner surface 66, or a groove portion whose depth gradually becomes shallower along the extension direction in accordance with groove portion 10 may be provided.

[0056] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and can be appropriately modified without departing from the spirit of the present invention. For example, in the spacer body 1 of the fishing rod spacer S of the first embodiment, the circumferential groove width of the groove portions 10, 20 is gradually narrowed along the extension direction, but this is not limited to this. As shown in Figures 12(a) and (b), in addition to this configuration, a spacer body 1F in which the radial groove depth is gradually narrowed along the extension direction is also very good. With this configuration, a more sufficient amount of adhesive can be introduced into the adhesive surfaces formed by the grooves 10F and 20F, improving the fixing strength.

[0057] As shown in Fig. 13(a), a circumferential groove 26 may be provided to intersect (orthogonally) the groove portion 20 on the outer circumferential surface. In this case, as shown in Fig. 13(b), a spiral circumferential groove 27 may be provided. By providing such circumferential grooves 26, 27, the area into which the adhesive is introduced is expanded, improving the fixing strength. Note that the circumferential grooves 26, 27 may be provided on the groove portion 10 on the inner circumferential surface.

[0058] In addition, in the first embodiment, each groove portion 10 and each groove portion 20 is shown to have a narrow circumferential groove width in the same direction from the left side surface to the right side surface, but this is not limited to this and the groove widths may be provided in different directions on the inner and outer surfaces of the spacer body 1. With this configuration, for example, it is possible to attach the rod 50 to the inner peripheral surface from one end of the spacer body 1, and attach the attachment member 60 to the outer peripheral surface from the other end of the spacer body 1 on the opposite side. This has the advantage of expanding the variety of attachment operations.

[0059] In addition, in each of the above embodiments, the groove portions 10, 20, 10C, and 20C are shown formed in a straight line, but this is not limited to this, and they may be formed to be narrower in a stepped shape or shallower in a stepped shape. [Explanation of symbols]
