Technical Field

[0001] Cross-reference This application claims priority based on Japanese Patent Application No. 2022-145482 (filed on September 13, 2022), the entire content of which is incorporated herein by reference. The present invention relates to a reel seat and a fishing rod including the reel seat. Background Art

[0002] Conventionally, various fishing rods including a reel seat for a fishing rod have been known.

[0003] In such a fishing rod, generally, a reel seat for a fishing rod and a grip for a fishing rod are placed on the rod body, and in the reel seat for a fishing rod, a reel foot placement portion for placing the reel feet is formed on the upper side or the lower side of the main body.

[0004] As such a fishing rod, for example, Patent Document 1 discloses a first section rod 1 having a high-rigidity portion X on the rod-tail side of a reel seat 8 and a low-rigidity portion Y having a lower rigidity than the high-rigidity portion X on the rod-tip side of the high-rigidity portion X. Even when a fisherman supports the first section rod 1 by abutting the rod-tail side end portion against the elbow or the abdomen while holding the vicinity of the reel seat 8, since the high-rigidity portion X can maintain sufficient rigidity, this portion is not easily bent, and thus the first section rod 1 and even the entire fishing rod can be supported in a stable state.

[0005] In addition, Patent Document 2 discloses a telescopic draw rod. A reel seat 4 is mounted on a first section rod 2, and a fishing line guide 6 is mounted on a rod-top side portion 1a on the rod-top side of a rod-tip section 1. The rod-top side portion 1a is configured to have a higher rigidity than a rod-tail side portion 1b. The rod-tail side portion 1b is located on the rod-tail side of the rod-top side portion 1a and is configured such that while the rod-tail side portion 1b is held in a state of being housed in the first section rod 2, the rod-tail side portion 1b can be held in an extended state of being pulled out toward the rod-top side of the first section rod 2, and in the extended state, the rod-tail side portion 1b is easily bent by the pulling force of a fish.

[0007] Conventionally, there has been a fishing rod having a structure in which the front part of the reel seat body is more rigid than the tail part of the rod tube. In particular, in a fishing rod having an offset reel seat, when a structure is adopted in which the rod tube does not penetrate through the offset reel seat, in order to maintain the strength of the reel seat, the reel seat body is made of a metal material, or in the case of a resin material, the strength is ensured by thickening the wall thickness, so that the rigidity of the reel seat body becomes large. However, it has been found that there is the following problem. When a load is applied to the rod tube, when the rigidity of the front end portion of the reel seat connected to the rod tube increases, stress concentration is caused on the rod tube in the front part of the reel seat, resulting in easy breakage of the rod tube. In this regard, in the first section rod related to Patent Document 1, there is the following problem, that is, the low-rigidity portion Y with low rigidity causes more stress concentration than the high-rigidity portion X located on the tip side of the rod. On the other hand, in the fishing rod related to Patent Document 2, only the tip side portion of the rod has higher rigidity than the rod tail side portion located more towards the rod tail side, and the problem of easy stress concentration on the rod tube in the front part of the reel seat resulting in rod tube breakage has not been solved.

[0008] The present invention has been made in view of the above circumstances, and the technical problem to be solved is to provide a reel seat and a fishing rod having the reel seat, which can prevent the generation of stress concentration on the tail part of the rod tube by adjusting the bending rigidity of the cylindrical portion and the intermediate connecting portion of the reel seat even when a structure is adopted in which the position of the reel foot placement portion of the reel seat is offset in the direction of falling into the axis of the first section rod. Thus, even in an offset structure, breakage is not likely to occur on the tail part of the rod tube, and the durability and strength of the rod can be greatly improved. The above-mentioned objects of the present invention other than the above can be understood from the whole of this specification.

[0009] The reel seat according to an embodiment of the present invention is mounted on a rod body and includes: a reel seat body having a reel foot placement portion for placing a reel foot, a fixed cover provided on the front side or the rear side in the axial direction of the reel foot placement portion, a cylindrical portion provided on the rear side or the front side in the axial direction of the reel foot placement portion, and an intermediate connecting portion connecting the cylindrical portion to a front or rear cylindrical portion in the axial direction; a moving cover provided on the rear side or the front side in the axial direction of the reel foot placement portion; and a nut member provided on the outer surface of the cylindrical portion and capable of moving the moving cover by rotation. The feature is that the bending rigidity of the intermediate connecting portion of the reel seat body is the same as or lower than the bending rigidity of the tail part of the rod body.

[0010] In the reel seat according to an embodiment of the present invention, in the downward direction in the vertical direction of the reel seat, the bending rigidity of the intermediate connecting portion of the reel seat body is in the range of 0.8 to 1.0 with respect to the bending rigidity of the tail part of the rod body.

[0011] In the reel seat according to an embodiment of the present invention, the bending rigidity of the lower part of the reel mounting portion of the reel seat body is 4 to 6 times in the lateral direction with respect to its longitudinal direction.

[0012] The fishing rod according to an embodiment of the present invention is configured to include any one of the above-described reel seats and a rod body.

[0013] According to the above embodiment, even when a structure is adopted in which the position of the reel foot mounting portion of the reel seat is shifted in the direction of falling into the axis of the first section of the rod, it is possible to prevent the generation of stress concentration on the tail portion of the rod tube by adjusting the bending rigidity on the cylindrical portion and the intermediate connecting portion of the reel seat. Thus, even in the offset structure, it is not easy to cause breakage on the tail portion of the rod tube, and thereby the durability and strength of the rod can be significantly improved. The reel seat and the fishing rod including the reel seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Hereinafter, embodiments of the reel seat and the fishing rod according to the present invention will be specifically described with reference to the drawings. In a plurality of drawings, the same reference numerals are assigned to common components through the plurality of drawings. For ease of explanation, it should be noted that each drawing is not necessarily described at an accurate scale.

[0016] Figure 1This is a diagram showing an embodiment of the fishing rod related to the present invention. As shown in the figure, the fishing rod 1 of an embodiment of the present invention includes: a rod body 2; a reel 6, which is mounted on the rod body 2 through a reel seat 9; and a fishing line guide 10, which is mounted on the rod body 2. In the illustrated embodiment, the reel seat 9 and the fishing line guide 10 respectively correspond to mounting parts mounted on the outer peripheral surface of the rod body.

[0017] The rod body 2 is formed, for example, by connecting a tip rod 3, a middle rod 5, a rod tip section 7, etc. These rod bodies are, for example, joined by a plug-in connection. The tip rod 3, the middle rod 5, and the rod tip section 7 can be joined by a pull-out method, an inverse plug-in method, a sleeve method, or any other known arbitrary joining method. The rod body 2 can also be composed of a single rod body.

[0018] The tip rod 3, the middle section 5, and the rod tip section 7 are, for example, formed of a tubular body made of a fiber-reinforced resin. The tubular body made of the fiber-reinforced resin is manufactured by winding a fiber-reinforced resin polyester film (prepreg film) impregnated with a matrix resin in reinforcing fibers around a mandrel and heating the prepreg film to cure it. As the reinforcing fibers contained in the prepreg film, for example, carbon fibers, glass fibers, and any other known reinforcing fibers can be used. As the matrix resin contained in the prepreg film, a thermosetting resin such as an epoxy resin can be used. After the prepreg film is cured, the mandrel is removed. In addition, the outer surface of the tubular body is appropriately polished. Each rod body can also be configured to be solid.

[0019] In the illustrated embodiment, on the tip rod 3, the middle rod 5, and the rod tip section 7, a plurality of fishing line guides 10 (fishing line guides 10A to 10D) for guiding the fishing line released from the reel 6 mounted on the reel seat 9 are provided. More specifically, a fishing line guide 10A is provided on the tip rod 3, a fishing line guide 10B is provided on the middle rod 5, and a fishing line guide 10C is provided on the rod tip section 7. Although a top guide 10D is provided at the top of the rod tip section 7, detailed description thereof is omitted.

[0020] Next, refer to Figure 2 to describe the basic structure of the reel seat body 12 and the reel seat 9. In the following description, the axial direction (front-rear direction) and the up-down direction refer to Figure 2 the directions shown in Figure 2 and the left-right direction (lateral direction) refers to the direction orthogonal to the Figure 2 drawing surface of

[0021] The spool holder body 12 has a spool foot placement surface 12a along its axial direction for placing the spool foot 6a of the fishing spool 6. The spool holder body 12 can be configured, for example, to have a length in the range of 150 mm to 200 mm, but is not limited thereto. In addition, the spool holder body 12 is formed with a raised portion (trigger) 12b having an outer surface with a curved shape. The outer surface with the curved shape slightly raises the opposite side of the spool foot placement surface 12a, so that when held by the gripping hand, by supporting the thumb pad or its vicinity, it is convenient to hold. Additionally, it can also be configured to connect the rod body to the rear side of the spool holder body 12.

[0022] The spool foot placement surface 12a of the spool holder body 12 is formed flat, or is formed to have a greater curvature and be substantially flat than other circumferential portions (such as the trigger 12b) adjacent to the spool foot placement surface 12a of the spool holder body 12, and is formed Figure 2 in the state of extending in the axial direction of the spool holder body 12 as shown. On the spool holder body 12, a fixed cover 14 is integrally provided at one end (rod tail side). One end of the spool foot placement surface 12a of the spool holder body 12 is disposed inside the fixed cover 14.

[0023] On the spool holder body 12, a movable cover 13 is movably mounted in the axial direction at the other end (rod tip side). In the state where the spool foot 6a is placed on the spool foot placement portion 12a and its rear end side is inserted into the fixed cover 14, by tightening the front end side with the axially moving movable cover 13, the fishing spool 200 can be installed and fixed on the spool holder 9. Additionally, although the spool holder 9 includes the spool holder body 12 and the movable cover 13, it can also include components other than these.

[0024] Refer to again Figure 2, a more detailed description of the spool seat according to an embodiment of the present invention will be given. As shown in the figure, the spool seat 9 according to an embodiment of the present invention is mounted on the rod body 2 and includes: a spool seat body 12 having a spool foot placement portion 12a for placing the spool foot 6a, a fixed cover 14 provided on the axially rear side (rod tail side) of the spool foot placement portion 12a, and a tubular portion 15 provided on the axially front side (rod tip side) of the spool foot placement portion 12a and partially cut away; a moving cover 13 provided on the axially front side (rod tip side) of the spool foot placement portion 12a; and a nut member 18 provided on the outer surface of the tubular portion 15 and capable of moving the moving cover 13 by rotation. The tubular portion 15 has a cylindrical portion 21 and a concave portion 22 partially cut away. The moving cover 13 has an engaging portion 16 provided on the inner surface of the tubular portion 15 and a cover portion 17 for accommodating at least a part of the spool foot 6a. The nut member 18 is provided so as to be relatively rotatable with respect to the concave portion 22 on the outer surface of the concave portion 22. The inner surface 18a of the nut member 18 engages with the engaging portion 16, and the moving cover 13 can be moved toward the axially rear side (rod tail side) by the rotation of the nut member 18. The rod body 2 is configured to be inserted into the cylindrical portion 21 of the tubular portion 15.

[0025] Next, with reference to Figure 2 and 3 a further description of the spool seat according to an embodiment of the present invention will be given. A tubular portion 15 is provided in front of the spool seat body 12 of the spool seat 9, and a grip portion (rear grip) 23 to be held and grasped is fixed at the rear. The spool seat body 12 has an intermediate connecting portion 24 that connects the tubular portion 15 and the rear tubular portion 4b in the axial direction, and they are integrally formed. The outer peripheral surface of the proximal end side of the rod body 2 constituting the fishing rod is fixed to the inner surface of the tubular portion 15 by bonding or the like. The grip portion 23 is fixed to the outer peripheral surface of a tubular protrusion 4a that protrudes rearward along the axial center direction of the spool seat body 12 and is configured to be flush with the surface of the rear tubular portion 4b. At this time, the rear tubular portion 4b is also a part held and grasped together with the grip portion 23 and can form a grip. In addition, for the fishing rod 1 on which the spool seat 9 is fixed, it can be a pull-out type, a joint type, a single rod, etc., and its configuration is not limited. In Figure 2 a part of the fishing rod (a part of the rod body) is shown, and the overall configuration is omitted. In addition, an example in which the spool seat 9 is mounted and fixed with a low-profile double-bearing reel (hereinafter also referred to as a reel) as a fishing reel 6 is shown.

[0026] The movable cover 13 includes a snap-fitting portion 16 formed with an external thread portion and a cover portion 17 that is bent radially inward and accommodates at least a portion of the reel leg 6a. The cover portion 17 is arranged to enter an opening 8 formed below the front end surface (end surface of the cylindrical portion 15) of the intermediate connecting portion 24, and the opening 8 is connected to the reel leg loading portion 12a. That is, when the movable cover 13 moves to the rear side, the cover portion 17 is inserted into the front end portion of the reel leg 6a loaded on the reel leg loading portion 12a in the opening 8.

[0027] The external threaded portion of the engaging portion 16 of the movable cover 13 is screwed with the internal threaded portion formed on the inner surface 18a of the nut member 18 embedded in the cylindrical portion 15 (or the concave portion 22 of the cylindrical portion 15). That is, by rotating the nut member 18 in one direction, the movable cover 13 can be moved to the axial rear side and tighten the front end side of the reel foot 6a (the installation and fixing state of the reel), and by rotating the nut member 18 in another direction, the movable cover 13 can be moved to the axial front side and release the front end side of the reel foot 6a (the disassembly state of the reel). Here, the engaging method of the engaging portion 16 and the inner surface of the nut member 18 can consider various existing known methods, and is not limited to a specific form (screwing). In addition, a circumferential groove is formed along the circumferential direction on the front end side of the cylindrical portion 15, and by installing an annular member (retaining ring) 20 on this part, the nut member 18 can be restricted so that it will not fall out to the front side.

[0028] On the outside of the reel seat body 12, a handle support portion 25 is bonded adjacent to the nut component 18, and a handle portion (front handle) 26 is fixed to the handle support portion 25. The handle support portion 25 is arranged to be flush with the surface of the nut component 18 that is rotated, but the handle portion 26 may not be provided.

[0029] Next, refer to Figure 5 A cross-sectional structure of the reel seat 9 according to one embodiment of the present invention will be described. Figure 5 Yes means Figure 2 As shown in the figure, the reel seat 9 according to one embodiment of the present invention is in a state where the rod body 2 is inserted (and the movable cover 13 is located at Figure 2 In the case of the position of the cylindrical portion 15, the Figure 5In the downward direction in the vertical direction of the drawing surface (the downward direction), when observing a cross-section perpendicular to the axial direction of the cylindrical portion 15, the rod body 2, the moving cover (the engaging portion 16), and the reel seat body 12 (the cylindrical portion 15 or the cylindrical portion 21) are sequentially provided from the inside. As shown in the figure, the outer surface of the cylindrical portion 21 of the cylindrical portion 15 of the reel seat body 12 forms a circular or substantially circular shape, and the inner surface forms a space capable of accommodating the cylindrical rod body 2 and the bent engaging portion 16. The internal shape of the cylindrical portion 21 can be variously considered according to the size of the rod body or the shape of the engaging portion 16, and is not limited to a specific form.

[0030] Thus, on the reel seat 9 according to an embodiment of the present invention, the rod body 2 can be inserted into a thicker portion of the reel seat body 12 inside the reel seat (the cylindrical portion 21 of the cylindrical portion 15 is thicker than the concave portion 22), so that even when the structure in which the position of the reel foot mounting portion with the reel seat is shifted in the direction of falling into the axis of the first-stage rod is adopted, it can correspond to either a circular or low-profile double-axis reel, and the strength is not easily reduced, and the durability of the reel seat can be greatly improved.

[0031] Next, refer to Figure 4 The cross-sectional structure of the reel seat 9 according to an embodiment of the present invention will be described. Figure 4 It represents Figure 2 The B-B cross-sectional view of. As shown in the figure, in the state where the rod body 2 is inserted into the reel seat 9 according to an embodiment of the present invention (and when the moving cover 13 is located at Figure 2 In the case of the position), when observing a cross-section perpendicular to the axial direction of the cylindrical portion 15 in the direction from the central axis of the cylindrical portion 15 upward ( Figure 4 The upward direction in the vertical direction of the drawing surface), the rod body 2, the reel seat body 12 (the cylindrical portion 15 or the concave portion 22), and the nut member 18 are sequentially provided from the inside. When observing a cross-section perpendicular to the axial direction of the cylindrical portion 15 in the direction from the central axis of the cylindrical portion 15 downward ( Figure 4 The downward direction in the vertical direction of the drawing surface), the rod body 2 and the nut member 18 are sequentially provided from the inside, and a space for the moving cover 13 to pass through is formed between the rod body 2 and the nut member 18. Thus, the engaging portion 16 of the moving cover 13 can move back and forth along the axial direction of the reel seat 9 in the cut-off portion of the concave portion 22 of the cylindrical portion 15. Here, as Figure 4As shown, the concave portion 22 is formed into a concave shape having an opening in the downward direction, whereby the weight reduction of the cylindrical portion 15 of the spool holder body 12 can be achieved. Thus, although the cylindrical portion 15 includes the cylindrical portion 21 and the concave portion 22 and does not form a complete cylindrical shape, it can be referred to as the cylindrical portion 15 from which a part thereof is cut off (the same applies to the entire present specification).

[0032] Next, with reference to Figure 6 the structure of the moving cover 13 on the spool holder 9 according to an embodiment of the present invention will be described. Figure 6 (a) and (b) are both perspective views (the former is a view observed obliquely from above, and the latter is a view observed obliquely from below). As shown in the figure, the moving cover 13 includes an engaging portion 16 and a cover portion 17. When observed in a cross-section ( Figure 4 the cross-section shown) perpendicular to the axial direction of the cylindrical portion 15, the engaging portion 16 is formed in an arc shape or is curved. Thus, the inner surface is in close contact with and firmly adhered to the surface of the rod body 2. In addition, an external thread portion provided on the outer surface can be screwed with an internal thread portion formed on the inner surface 18a of the nut member 18. In addition, the angle of the arc of the engaging portion 16 of the moving cover 13 formed in an arc shape is in the range of 70 degrees to 90 degrees.

[0033] In addition, as Figure 6 shown, on the moving cover 13 of the spool holder according to an embodiment of the present invention, when observed in the radial direction of the central axis of the spool holder 9, the engaging portion 16 and the cover portion 17 are offset (when observed in the radial direction of the central axis of the spool holder 9, the cover portion 17 is formed on the inner side of the engaging portion 16). In addition, when the engaging portion 16 and the cover portion 17 are offset, between the engaging portion 16 and the cover portion 17, there is a connecting portion 19 that extends perpendicular to the central axis of the spool holder 9 and connects the engaging portion 16 and the cover portion 17. Thus, by adjusting the length of the connecting portion 19, the rod body itself can be inserted into the portion of the spool holder body that has a thick-walled structure.

[0034] The reel seat 9 according to one embodiment of the present invention is mounted on the rod body 2 and includes: a reel seat body 12 having a reel foot placement portion 12a for placing the reel foot 6a, a fixed cover 14 provided on the front or rear side in the axial direction of the reel foot placement portion 12a, a cylindrical portion 15 provided on the rear or front side in the axial direction of the reel foot placement portion 12a, and an intermediate connection portion 24 connecting the cylindrical portion 15 to the front or rear cylindrical portion 4b in the axial direction; a movable cover 13 provided on the rear or front side in the axial direction of the reel foot placement portion 12a; and a nut member 18 provided on the outer surface of the cylindrical portion 15, capable of moving the movable cover by rotation, and the bending rigidity of the intermediate connection portion 24 of the reel seat body 12 is the same as or lower than the bending rigidity of the tail portion of the rod body.

[0035] According to the reel seat 9 of one embodiment of the present invention, it is possible to provide a reel seat and a fishing rod having the reel seat, which can prevent stress concentration on the tail portion of the rod tube by adjusting the bending rigidity of the cylindrical portion and the intermediate connection portion of the reel seat even when the position of the reel foot placement portion of the reel seat adopting a structure that deviates in the direction of falling into the axis of the first section of the rod, and thus, even in an offset structure, it is not easy to break on the tail portion of the rod tube, thereby greatly improving the durability and strength of the rod.

[0036] In the reel seat 9 according to one embodiment of the present invention, in the lower direction in the vertical direction of the reel seat 9 ( Figure 2 the vertical direction shown (the vertical direction described later Figure 7 the vertical direction shown), the same hereinafter), the bending rigidity of the intermediate connection portion 24 of the reel seat body 12 is in the range of 0.8 to 1.0 with respect to the bending rigidity of the cylindrical portion 15 of the reel seat body 12. In this way, the durability (or strength) of the rod can be improved.

[0037] In the reel seat 9 according to one embodiment of the present invention, the bending rigidity of the lower part of the reel placement portion of the reel seat body is 4 to 6 times in the transverse direction with respect to its longitudinal direction. In this way, the casting accuracy can be improved.

[0038] Next, with reference to Figure 7 the reel seat 9 according to one embodiment of the present invention will be further described. Figure 7and the following shows the flexural rigidity at each position observed in the extending direction of the reel seat. Position A is the position of the nut engaging portion of the cylindrical portion 15, and position B is the position of the front portion of the reel support of the cylindrical portion 15. In addition, position C is the position of the lowest rigidity portion of the lower part of the reel support of the intermediate connecting portion 24, position D is the position of the convex portion of the lower part of the reel support of the intermediate connecting portion 24, and position E is the position of the front portion of the trigger of the intermediate connecting portion 24. In addition, position F is the position of the connecting portion between the rear cylindrical portion 4b and the grip. Position X is the position of the rear end portion of the first joint rod tube (fitting member), range Y is the range between the first joint rod tube (fitting member) and the front portion of the reel support, and position Z is the position where stress concentration occurs in the first joint rod tube (the tail portion of the rod body) of the fitting member 27.

[0039] As shown in the following table, the flexural rigidities (in the up-and-down direction) at position B and position F are 63.7 and 66.9 respectively, which are configured to be larger than other positions. At position A, the flexural rigidity (in the up-and-down direction) is lower than that at position B and position F, but is 42.8. At positions C, D, and E, the flexural rigidities (in the up-and-down direction) are 5.1, 7.6, and 6.4 respectively, which are lower than that at position B. Thus, the lowest rigidity can be reduced relative to the rigidity of the rod tube tail portion of 6.0. In addition, the flexural rigidities (in the lateral direction) at positions C, D, and E are 27.5, 33.0, and 33.9 respectively, and it can be seen that they are 4.9 to 5.4 times that in the up-and-down direction.

[0040] Position A B C D E F Vertical direction <![CDATA[(EI 10^6kgf / mm 2 )]]> 42.8 63.7 5.1 7.6 6.4 66.9 Horizontal direction <![CDATA[(EI 10^6kgf / mm 2 )]]> 27.5 33.0 33.9

[0041] When using a fishing rod equipped with a reel seat according to an embodiment of the present invention to wrestle with a fish, when the fishing reel is lifted upward, a downward force is applied to the tip of the rod. At this moment, since stress is likely to concentrate in the range of Y and breakage occurs, it is necessary to increase the flexural rigidity. On the other hand, it is known that when the flexural rigidity of the entire reel seat body 12 is increased, stress is likely to concentrate near the above-mentioned position Z and breakage occurs. Therefore, by reducing the flexural rigidity of the lower side of the reel seat body 12 and the reel foot placement portion 12a, stress concentration at position Z can be prevented. In addition, in order to cause the entire lower part of the reel seat to bend so that stress concentration does not occur in a specific part of the lower part of the reel seat and reduce the durability (or strength) of the reel seat, the flexural rigidity of the convex portion at position D where the finger is hooked and the position E near the tip of the reel foot 6a is reduced. In addition, the lowest flexural rigidity of the reel seat body 12 is 80% to 100% relative to the flexural rigidity at position Z. In addition, although when casting (throwing), the fishing rod swings laterally with respect to the reel seat body 12, in order to reduce the jitter during casting (throwing), it is necessary to increase the lateral flexural rigidity of the reel seat body 12. Specifically, by adopting the above-mentioned flexural rigidity values, the casting accuracy can be improved.

[0042] The fishing rod 1 according to an embodiment of the present invention is configured to include any one of the above-described reel seats 9 and a rod body 2.

[0043] According to a fishing rod having a reel seat according to an embodiment of the present invention, it is possible to provide a reel seat and a fishing rod having the reel seat that can prevent stress concentration from occurring at the tail of the rod tube by adjusting the bending rigidity of the cylindrical portion and the intermediate connecting portion of the reel seat even when the position of the reel foot mounting portion of the reel seat having a reel seat is offset in the direction of the axis of the first-stage rod, and thus, even in an offset structure, it is not easy to break at the tail of the rod tube, thereby significantly improving the durability and strength of the rod.

[0044] Here, in the reel seat 9 according to an embodiment of the present invention, the reel seat body 12 can be formed of carbon fiber reinforced plastic (CFRP), glass fiber reinforced plastic (GFRP), Al, or Mg. In addition, as the raw material of the reel seat 12, it can also be formed of GFRTP (continuous fiber), GFRTP (discontinuous fiber), CFRTP (continuous fiber), CFRTP (discontinuous fiber), or hybrid fiber.
