Description

[Technical Field]

[0001] The present invention relates to a reel seat and a fishing rod equipped with the same. [Background technology]

[0002] 2. Description of the Related Art Various fishing rods equipped with fishing rod reel seats have been known in the past.

[0003] In such fishing rods, a fishing rod reel seat and a fishing rod grip are usually placed on the rod body, and the fishing rod reel seat has a reel leg mounting portion formed on the upper or lower side of the main body for mounting the reel legs.

[0004] Known examples of such fishing rod reel seats include those in which the position of the reel leg mounting portion of the reel seat is offset downward relative to the axis of the butt rod (also referred to as offset reel seats), as disclosed in Patent Documents 1 to 3. With such offset reel seats, the reel leg mounting portion is shifted downward, so when a round double-bearing reel is attached, the thumb operating position does not become higher even when gripping the rear grip portion, preventing the palm from opening and reducing operability. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Publication No. 49-122082 [Patent Document 2] Jikko No. 49-46557 [Patent Document 3] Jikko No. 50-24539 Summary of the Invention [Problem to be solved by the invention]

[0006] Although the reel seats disclosed in these patent documents facilitate clutch operation even on double-bearing reels in which the clutch lever that puts the spool into a free-spinning state during casting is positioned so as to protrude from the surface of the side plate, depending on the type of reel to be attached, the offset may be too large, making operability poor. While the offset must be set appropriately to accommodate the so-called low-profile reels that have become mainstream in recent years, it has been difficult to determine an appropriate offset amount that takes into account the reel being used. Furthermore, because the reel seat's reel leg mounting portion is offset downward relative to the axis of the butt rod, the strength of the reel seat in the area of ​​the reel seat leg mounting portion is significantly reduced, and stress is concentrated in the area of ​​the end face of the butt joint of the reel seat, which can easily cause fractures or damage depending on the usage pattern, resulting in an essential problem of durability.

[0007] The present invention has been made in consideration of the above circumstances, and its purpose is to provide a reel seat that is compatible with both round and low-profile double-shaft reels, and that not only improves operability but also significantly increases durability by employing a reel seat with a more appropriate offset amount, and a fishing rod equipped with the reel seat. Other objects of the present invention will become apparent by reading this entire specification. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, embodiments of a reel seat and a fishing rod according to the present invention will be described in detail with reference to the accompanying drawings. Components common to multiple drawings are designated by the same reference numerals throughout the multiple drawings. Please note that the drawings are not necessarily drawn to scale for the sake of convenience.

[0020] 1 is a diagram showing one embodiment of a fishing rod according to the present invention. As shown in the figure, a fishing rod 1 according to one embodiment of the present invention comprises a rod body 2, a reel 6 attached to the rod body 2 via a reel seat 9, and a fishing line guide 10 attached to the rod body 2. In the illustrated embodiment, each of the reel seat 9 and the fishing line guide 10 corresponds to an attachment part attached to the outer circumferential surface of the rod body.

[0021] The rod body 2 is constructed by connecting, for example, a butt rod 3, a middle rod 5, and a tip rod 7. These rod bodies are joined, for example, using a straight joint. The butt rod 3, middle rod 5, and tip rod 7 can be joined using a telescoping method, a reverse straight joint method, a spigot joint method, or any other known joining method. The rod body 2 may also be constructed from a single rod body.

[0022] The butt rod 3, middle rod 5, and tip rod 7 are each constructed, for example, as a tubular body made of fiber-reinforced resin. This fiber-reinforced resin tubular body is produced by winding a fiber-reinforced resin prepreg (prepreg sheet) in which reinforcing fibers are impregnated with a matrix resin around a core and then heating and curing the prepreg sheet. The reinforcing fibers contained in the prepreg sheet can be, for example, carbon fiber, glass fiber, or any other known reinforcing fiber. The matrix resin contained in the prepreg sheet can be a thermosetting resin such as epoxy resin. After the prepreg sheet has cured, the core is removed. The outer surface of the tubular body is polished as appropriate. Each rod body may be constructed in a solid shape.

[0023] In the illustrated embodiment, the butt rod 3, middle rod 5, and tip rod 7 are provided with a plurality of line guides 10 (line guides 10A-10D) that guide the fishing line that is let out from the reel 6 attached to the reel seat 9. More specifically, the butt rod 3 is provided with line guide 10A, the middle rod 5 is provided with line guide 10B, and the tip rod 7 is provided with line guide 10C. A top guide 10D is provided at the tip of the tip rod 7, but details will be omitted.

[0024] Next, the basic configuration of the reel seat main body 12 and the reel seat 9 will be described with reference to Figure 2. In the following description, the axial direction (front-rear direction) and the up-down direction refer to the directions shown in Figure 2, and the left-right direction (side direction) refers to the direction perpendicular to the plane of the paper in Figure 2. In other words, the front refers to the tip side of the fishing rod, the rear refers to the base side, the top refers to the reel side with respect to the axis X of the butt rod (rod) when a dual-bearing reel is attached, and the bottom refers to the opposite side.

[0025] The reel seat body 12 has a reel leg support surface 12a along its axial direction on which the reel legs 6a of the fishing reel 6 are placed. The reel seat body 12 can be configured to have a length ranging from 150 mm to 200 mm, for example, but is not limited to this. The reel seat body 12 also has a slightly bulging side opposite the reel leg support surface 12a, forming a bulging portion (trigger) 12b with a curved outer surface that supports the ball of the foot or its vicinity when gripped with the gripping hand, making it easy to grip. The reel seat body 12 may also be configured so that a fishing rod body is attached to the rear side of the reel seat body 12.

[0026] The reel leg mounting surface 12a of the reel seat body 12 can be formed flat or substantially flat with a larger curvature than other circumferential portions (for example, the trigger 12b) adjacent to the reel leg mounting surface 12a of the reel seat body 12, and is formed to extend in the axial direction of the reel seat body 12 shown in Figure 2. A fixed hood 14 is integrally disposed at one end (rod base side) of the reel seat body 12. One end of the reel leg mounting surface 12a of the reel seat body 12 is disposed inside the fixed hood 14.

[0027] As will be described in detail later, a movable hood 13 is attached to the other end (rod tip side) of the reel seat body 12 so as to be movable in the axial direction. The fishing reel 6 is attached and fixed to the reel seat 9 by placing the reel leg 6a on the reel leg mounting portion 12a, fitting its rear end into the fixed hood 14, and then fastening its front end with the movable hood 13 which moves in the axial direction. The reel seat 9 includes the reel seat body 12 and the movable hood 13, but may include other components.

[0028] A reel seat 9 according to one embodiment of the present invention is a reel seat 9 attached to a fishing rod body 2, and comprises: a reel leg support portion 12a on which the reel leg 6a of a fishing reel 6 is placed; a fixed hood 14 provided on the axial rear side of the reel leg support portion 12a; a cylindrical portion 15 provided on the axial front side of the reel leg support portion 12a and having a portion cut out; a movable hood 13 provided on the axial front side of the reel leg support portion 12a; and a nut member 18 provided on the outer surface of the cylindrical portion 15 and capable of moving the movable hood 13 by rotation; and the reel leg support portion 12a is configured to be offset in the range of 2.5 mm to 4.0 mm from a reference position in the direction opposite to the side on which the reel leg 6a is placed, as viewed from the reel leg support portion 12a. Alternatively, a reel seat 9 according to one embodiment of the present invention is a reel seat 9 comprising a reel seat body 12 having a reel leg support 12a on which the reel leg 6a is placed and a fixed hood 14 provided on one axial side of the reel leg support 12a, and a movable hood 13 provided on the other axial side of the reel leg support 12a, in which the base joint 2a of the fishing rod body 2 is provided on the front side of the reel seat body 12 and a grip attachment material 11 is provided on the rear side of the reel seat body 12, both of which are horizontally arranged in the axial direction, and the reel leg support 12a is configured to be offset in the range of 2.5 mm to 4.0 mm from a reference position in the direction opposite the side on which the reel leg 6a is placed, as seen from the reel leg support 12a. Here, in the reel seat according to one embodiment of the present invention, the reference position is the position (height position) of the grip attachment material or the central axis of the fishing rod body (the same applies throughout this specification). When the offset is more positive than the reference position, the reel seat is not essentially offset, and when the offset is more negative than the reference position, the reel seat is in an offset state (a state in which part of the reel is recessed into the reel seat). An offset state is a state in which part of the reel is recessed into the reel seat when installed, and the greater the offset amount (i.e., the more negative the offset value), the deeper the part of the reel is recessed into the reel seat.

[0029] The reel seat 9 according to one embodiment of the present invention is compatible with both round and low-profile spinning reels, and by adopting a reel seat with a more appropriate offset amount, it is possible to provide a reel seat that is not only easier to use but also less likely to lose strength and significantly increases durability, as well as a fishing rod equipped with the reel seat.

[0030] In one embodiment of the present invention, in a reel seat 9, the reel leg support portion 12a is offset from the reference position so that the thumbing height of the reel 6 placed on the reel leg support portion 12a is in the range of 5.0 mm to 10.0 mm from the reference position.

[0031] The reel seat 9 according to one embodiment of the present invention is compatible with both round and low-profile spinning reels, and by adopting a reel seat with a more appropriate offset amount, it is possible to provide a reel seat that is not only easier to use but also less likely to lose strength and significantly increases durability, as well as a fishing rod equipped with the reel seat.

[0032] Next, we will explain the thumbing position and offset amount of the reel seat 9 according to one embodiment of the present invention. When a user casts a fishing rod equipped with a reel seat with a reel attached, he or she places his or her index finger on the trigger, grips the grip with the palm of the hand, and thumbs the reel spool. It has been found that operability improves if the reel spool can be thumbed within the range of movement of the thumb without the middle, ring, and little fingers gripping the fishing rod and the palm of the hand opening. This thumbing position is determined by the clutch position when the reel's clutch lever is OFF. If the thumbing position is too low, problems such as difficulty in disengaging the clutch occur. Therefore, it has been found that operability improves when the thumbing position (clutch OFF position) relative to the top (top surface) of the fishing rod grip is between 4 mm and 12 mm, more preferably between 5 mm and 10 mm.

[0033] Table 1 below shows the thumbing (clutch off) height for each offset amount (-8.5mm, -5.5mm, -4.0mm, -3.2mm, -2.5mm, 3.5mm, 8.2mm) using reels with clutch positions of 27.5mm (round reel), 24.8mm (low profile reel A), two types of 23.9mm (low profile reel B), and 21.6mm (low profile reel C) when the clutch is off.

[0034] [Table 1]

[0035] As shown in Table 1, we checked the thumbing height (clutch off position) for each offset amount for five reels. We found that when the offset amount was between -2.5 mm and -4.0 mm, the thumbing height (clutch off position) was within the range of 4 mm to 12 mm. When the offset amount was -5.5 mm, the thumbing height (clutch off position) was within the range of 5 mm to 10 mm, except for low-profile reel C. From these results, we can see that the thumbing height (clutch off position) was best when the offset amount was between -2.5 mm and -4.0 mm. The second-best result was when the offset amount was -5.5 mm. On the other hand, when the offset amount was 8.2 mm or 3.5 mm, the thumbing height (clutch off position) was greater than 12 mm. Even when the offset amount was -8.5 mm, the thumbing height (clutch off position) was 6.0 mm, which was good for round reels, but was below 3.3 mm for other reels.

[0036] Next, the results of an operation test on the offset amount of the reel seat 9 according to one embodiment of the present invention will be described. In this operation test, the clutch positions at clutch off were 27.5 mm (round reel (referred to as type I)), 24.8 mm (low-profile reel A (referred to as type II)), 23.9 mm (low-profile reel B (referred to as type III)), and 21.6 mm (low-profile reel C (referred to as type IV)), and the operability of the fishing rod was evaluated by 10 testers of different genders, ages, and physiques for each offset amount (-8.5 mm, -5.5 mm, -4.0 mm, -2.5 mm, 6.5 mm, 8.5 mm). The results are shown in Tables 2 and 3 below. The evaluation scores were out of 10, with 1 being the lowest rating and 10 being the highest rating, with 1 indicating that the rod was difficult to use, 2-5 indicating that there were some issues with it when using it, 6-8 indicating that it could be used without any problems, and 9 and 10 indicating that it could be used comfortably.In addition, an overall evaluation was conducted to determine the operability of the fishing rod, including casting, reeling, and lure action.

[0037] [Table 2]

[0038] [Table 3]

[0039] As shown in Tables 2 and 3, for the four reels, the offset range of -2.5 mm to -4.0 mm resulted in the highest performance ratings, including a maximum rating of 10 points. For the -5.5 mm offset range, although the number of ratings with the maximum rating of 10 points was low, many ratings of 7, 8, and 9 points were received, followed by the next highest performance ratings. On the other hand, for the -8.5 mm offset range, many ratings of 5 points or less were received, indicating that the performance ratings were not sufficient. Furthermore, offsets of +6.5 mm and +8.5 mm resulted in the lowest performance ratings. These performance test results demonstrate that the reel seat 9 according to one embodiment of the present invention provides high operability when the offset range is -2.5 mm to -5.5 mm, and more preferably, when the offset range is -2.5 mm to -4.0 mm.

[0040] In this way, the reel seat 9 according to one embodiment of the present invention is compatible with both round and low-profile spinning reels, and by adopting a reel seat with a more appropriate offset amount, it is possible to provide a reel seat that can improve operability, and a fishing rod equipped with the reel seat.

[0041] Referring again to Figure 2, a reel seat according to one embodiment of the present invention will be described in more detail. As shown in the figure, a reel seat 9 according to one embodiment of the present invention is a reel seat attached to a fishing rod body 2, and includes a reel leg mounting portion 12a on which a reel leg 6a is mounted, a fixed hood 14 provided on the axial rear side (rod butt side) of the reel leg mounting portion 12a, a cylindrical portion 15 provided on the axial front side (rod tip side) of the reel leg mounting portion 12a and having a portion cut out, a movable hood 13 provided on the axial front side (rod tip side) of the reel leg mounting portion 12a, and a nut member 18 provided on the outer surface of the cylindrical portion 15 and capable of moving the movable hood 13 by rotation. In the reel 9, the tubular portion 15 has a cylindrical portion 21 and a recessed portion 22 with a portion cut out, the movable hood 13 has an engaging portion 16 provided on the inner surface of the tubular portion 15 and a hood portion 17 that accommodates at least a portion of the reel leg 6a, the nut member 18 is provided on the outer surface of the recessed portion 22 so as to be rotatable relative to the recessed portion 22, the inner surface 18a of the nut member 18 engages with the engaging portion 16, and the movable hood 13 can be moved axially rearward (toward the butt) by rotation of the nut member 18, and the rod body 2 is configured so as to be insertable up to the cylindrical portion 21 of the tubular portion 15. A protrusion can be provided on the end of the rod body 2. In this way, a rotation prevention structure can be adopted depending on the shape of the base end surface of the rod body 2. A spacer may also be used instead of the rod body 2. In that case, for example, the rod body may be connected to the spacer by a straight joint, or the rod body may be connected to the spacer by a spigot joint. Although the tubular portion 15 has been described as having a cylindrical portion 21 and a recessed portion 22 with a portion cut out, the recessed portion 22 may be provided so that it extends to at least a portion of the inside of the cylindrical portion 21 (i.e., in the tubular portion 15, the cylindrical portion 21 is provided on the outside, and the recessed portion 22 is provided on at least a portion of the inside thereof).

[0042] According to the reel seat of one embodiment of the present invention, even if a structure is adopted in which the position of the reel leg mounting portion of the reel seat is offset in a direction downward relative to the axis of the butt rod, it is possible to provide a reel seat that is compatible with both round and low-profile twin-shaft reels, is less likely to lose strength, and can significantly increase durability. More specifically, it is possible to insert the fishing rod body itself up to the part where the reel seat body has a thick structure, and a structure is adopted in which the engaging portion 16 of the movable hood 13 grips the rear of the fishing rod body, making it possible to realize a reel seat structure that is lightweight, compatible with low-profile twin-shaft reels, and has sufficient strength.

[0043] Next, a reel seat according to one embodiment of the present invention will be further described with reference to Figures 2 and 3. The reel seat body 12 of the reel seat 9 has a cylindrical portion 15 at its front, and a grip portion (rear grip) 23, which is gripped and held, fixed at its rear. The reel seat body 12 has an intermediate connecting portion 24 that axially connects the cylindrical portion 15 and the rear cylindrical portion 4b, and these are integrally formed. The base end side outer surface of the rod body 2 constituting the fishing rod is fixed to the inner surface of the cylindrical portion 15 by adhesive or the like. The grip portion 23 is fixed to the outer surface of a cylindrical protrusion 4a formed on the rear side of the reel seat body 12 and protrudes along the axial direction, and is configured to be flush with the surface of the rear cylindrical portion 4b. In this case, the rear cylindrical portion 4b is also gripped and held together with the grip portion 23 and can form a grip. The fishing rod 1 to which the reel seat 9 is fixed is not limited in its configuration and may be a telescopic type, a jointed type, a single rod, etc. Fig. 2 shows only a portion of the fishing rod (a part of the rod body) and does not show the entire configuration. Also, an example is shown in which the reel seat 9 is attached to and fixed to a low-profile dual-bearing reel (hereinafter also referred to as a reel) as the fishing reel 6.

[0044] The movable hood 13 includes an engaging portion 16 having a male thread formed thereon, and a hood portion 17 that is curved radially inward and accommodates at least a portion of the reel leg 6a. The hood portion 17 is disposed so as to fit into an opening 8 formed below the front end face of the intermediate connecting portion 24 (the end face of the cylindrical portion 15), and this opening 8 is connected to the reel leg mounting portion 12a. In other words, when the movable hood 13 moves rearward, the hood portion 17 fits into the opening 8 around the front end of the reel leg 6a mounted on the reel leg mounting portion 12a.

[0045] The male thread of the engaging portion 16 of the movable hood 13 is adapted to thread into a female thread formed on the inner surface 18a of a nut member 18 that is fitted onto the cylindrical portion 15 (or the recessed portion 22 of the cylindrical portion 15). That is, by rotating the nut member 18 in one direction, the movable hood 13 moves axially rearward and tightens the front ends of the reel legs 6a (reel attachment, fixed state). By rotating the nut member 18 in the other direction, the movable hood 13 moves axially forward and releases the front ends of the reel legs 6a (reel removal state). The method of engaging the engaging portion 16 with the inner surface of the nut member 18 can be any of a variety of conventionally known methods, and is not limited to a specific mode (threaded engagement). A circumferential groove is formed along the circumferential direction on the front end of the cylindrical portion 15. By attaching a ring-shaped member (retaining ring) 20 to this groove, the nut member 18 can be prevented from slipping out forward.

[0046] A grip support portion 25 is adhered to the outer surface of the reel seat body 12 adjacent to the nut member 18, and a grip portion (front grip) 26 is fixed on the grip support portion 25 so as to be flush with the surface of the nut member 18 that is rotated, but the configuration may also be such that the grip portion 26 is not provided.

[0047] In the reel seat 9 according to one embodiment of the present invention, the engaging portion 16 and the nut member 18 are adapted to be screwed together.

[0048] In the reel seat 9 according to one embodiment of the present invention, the rod body 2 is configured to be inserted or insertable into the cylindrical portion by a distance ranging from 5 mm to 20 mm in the axial direction of the cylindrical portion.

[0049] Next, with reference to Fig. 5, the cross-sectional structure of the reel seat 9 according to one embodiment of the present invention will be described. Fig. 5 shows the AA cross section of Fig. 2. As shown in the figure, when the reel seat 9 according to one embodiment of the present invention is viewed in a cross section perpendicular to the axial direction of the tubular portion 15 in a direction downward from the center axis of the tubular portion 15 (downward in the vertical direction of the paper surface of Fig. 5) with the fishing rod body 2 inserted (and the movable hood 13 in the position shown in Fig. 2), the fishing rod body 2, the movable hood (the engagement portion 16), and the reel seat main body 12 (tubular portion 15 or cylindrical portion 21) are provided in this order from the inside. As shown in the figure, the cylindrical portion 21 of the tubular portion 15 of the reel seat main body 12 has a circular or nearly circular outer surface, and its inner surface forms a space capable of accommodating the cylindrical fishing rod body 2 and the curved engagement portion 16. The internal shape of the cylindrical portion 21 can vary depending on the dimensions of the fishing rod body and the shape of the engagement portion 16, and is not limited to a specific form.

[0050] In this way, in the reel seat 9 of one embodiment of the present invention, the rod body 2 can be inserted up to the thicker part of the reel seat main body 12 inside the reel seat main body (the cylindrical portion 21 of the tubular portion 15 is thicker than the concave portion 22), so even if a structure is adopted in which the position of the reel leg mounting portion of the reel seat is offset in a downward direction relative to the axis of the base rod, it is possible to provide a reel seat that is compatible with both round and low-profile double-axis reels, is less likely to lose strength, and can significantly increase durability.

[0051] Next, with reference to Fig. 4, the cross-sectional structure of the reel seat 9 according to one embodiment of the present invention will be described. Fig. 4 shows the BB cross section of Fig. 2. As shown in the figure, in the reel seat 9 according to one embodiment of the present invention, when the fishing rod body 2 is inserted (and the moving hood 13 is in the position shown in Fig. 2), the fishing rod body 2, the reel seat main body 12 (the fishing rod body 15 or the recessed portion 22), and the nut member 18 are provided in this order from the inside when viewed in a cross section perpendicular to the axial direction of the cylindrical portion 15 in a direction upward from the center axis of the cylindrical portion 15 (upward in the vertical direction of the paper surface of Fig. 4); when the cross section perpendicular to the axial direction of the cylindrical portion 15 is viewed in a direction downward from the center axis of the cylindrical portion 15 (downward in the vertical direction of the paper surface of Fig. 4), the fishing rod body 2 and the nut member 18 are provided in this order from the inside, and a space through which the moving hood 13 passes is formed between the fishing rod body 2 and the nut member 18. In this way, the engaging portion 16 of the movable hood 13 is movable back and forth in the axial direction of the reel seat 9 in the notched portion of the recessed portion 22 of the tubular portion 15. Here, as shown in Figure 4, the recessed portion 22 is formed in a concave shape with an opening in the downward direction, thereby reducing the weight of the tubular portion 15 of the reel seat body 12. In this way, the tubular portion 15 includes the cylindrical portion 21 and the recessed portion 22, and although it does not form a complete cylindrical shape, it can be said to be a tubular portion 15 with a portion thereof cut out (the same applies throughout this specification).

[0052] Next, with reference to FIG. 6, the structure of the movable hood 13 in the reel seat 9 according to one embodiment of the present invention will be described. Both FIGS. 6(a) and 6(b) are perspective views (the former viewed from diagonally above, and the latter from diagonally below). As shown, the movable hood 13 includes an engagement portion 16 and a hood portion 17. When viewed in a cross section perpendicular to the axial direction of the cylindrical portion 15 (the cross section shown in FIG. 4), the engagement portion 16 is formed in an arc or curved shape. In this way, the inner surface is tightly and reliably bonded to the surface of the fishing rod body 2, and the male thread portion on the outer surface can be threaded with the female thread portion formed on the inner surface 18a of the nut member 18. The angle of the arc of the engagement portion 16 of the movable hood 13 is in the range of 70 to 90 degrees.

[0053] 6, in the movable hood 13 of the reel seat according to one embodiment of the present invention, the engagement portion 16 and the hood portion 17 are offset in the radial direction of the central axis of the reel seat 9 (the hood portion 17 is formed more inward than the engagement portion 16 in the radial direction of the central axis of the reel seat 9). When the engagement portion 16 and the hood portion 17 are offset, a connecting portion 19 is provided between the engagement portion 16 and the hood portion 17, extending perpendicular to the central axis of the reel seat 9 and connecting the engagement portion 16 and the hood portion 17. By adjusting the length of the connecting portion 19 in this way, the fishing rod body itself can be inserted up to the portion where the reel seat main body has a thick structure.

[0054] A fishing rod 1 according to one embodiment of the present invention is configured to include any of the reel seats 9 described above and a rod body 2.

[0055] According to a fishing rod equipped with a reel seat according to one embodiment of the present invention, even if a structure is adopted in which the position of the reel leg mounting portion of the reel seat is offset in a direction downward relative to the axis of the butt rod, it is possible to provide a fishing rod equipped with a reel seat that is compatible with both round and low-profile dual-shaft reels, is less likely to lose strength, and can significantly increase durability. More specifically, by adopting a structure that allows the rod body itself to be inserted up to the part where the reel seat main body has a thick structure, stress concentration in the weak parts can be prevented, making it possible to provide an offset reel seat structure with sufficient strength.

[0056] In the reel seat 9 according to one embodiment of the present invention, the reel seat body 12 can be made of carbon fiber reinforced plastic (CFRP), glass reinforced plastic (GFRP), Al, or Mg. The reel seat 12 may also be made of GFRTP (continuous fiber), GFRTP (discontinuous fiber), CFRTP (continuous fiber), CFRTP (discontinuous fiber), or a hybrid. By using such a material, it is possible to prevent an increase in weight while ensuring sufficient rigidity and strength.

[0057] Next, as shown in FIG. 7 , in a reel seat 9 according to one embodiment of the present invention, a first side recess 27 is formed on the lower side of the front region of the intermediate connector 24 of the reel seat body 12, and a second side recess 28 is formed on the lower side of the rear region of the intermediate connector 24. These first and second side recesses 27 and 28 may be provided as a pair on the left and right sides of the lower side of the intermediate connector 24. A recess may also be provided on the upper upper surface of the front region of the intermediate connector 24. The recesses on the first side recess 27 or the upper upper surface ensure clearance at the end of the reel seat, reducing the risk of contact with the fishing line. The provision of finger rest recesses on the side and upper surfaces helps to prevent rod wobble. Furthermore, the second side recess 28 makes it easier to hold the reel without a tight grip, and the position for placing your fingers is clear, enabling stable casting and reeling. As shown in the drawings, in the reel seat 9 according to one embodiment of the present invention, a bottom recess 29 is formed in the bottom of the central region of the intermediate connecting portion 24 of the reel seat body 12. In this way, when raising the fishing rod and reeling in the tackle, the index finger comes into contact with the bottom recess 29, preventing the fishing rod from slipping downward. Furthermore, by placing the middle finger on the bottom recess 29 to stabilize the fishing reel during casting, stability is increased, enabling improved casting accuracy. At least one or two of the first side recess 27, second side recess 28, and bottom recess 29 may be provided.

[0058] The dimensions, materials, and arrangement of each component described in this specification are not limited to those explicitly described in the embodiments, and each component can be modified to have any dimensions, materials, and arrangement that can be included in the scope of the present invention. Furthermore, components not explicitly described in this specification can be added to the described embodiments, and some of the components described in each embodiment can be omitted.
