Description

The present invention relates to a reel seat and a fishing rod equipped with the same.

Various fishing rods equipped with fishing rod reel seats have been known in the past.

In such fishing rods, a fishing rod reel seat and fishing rod grip are typically placed on top of the rod body, and the fishing rod reel seat has a reel leg mounting section formed on the upper or lower side of the main body for mounting the reel legs.

As an example of such fishing rod reel seats, reel seats (also known as offset reel seats) 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, as disclosed in Patent Documents 1 to 3, are known. 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 up and reducing operability.

The reel seats described 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 that it protrudes from the surface of the side plate. However, depending on the type of reel being fitted, the offset may be too large, making it difficult to use. While the offset must be set appropriately to accommodate the so-called low-profile reels that have become increasingly common in recent years, it has been difficult to determine an appropriate offset that takes into account the reel being used. Furthermore, because the reel seat's reel leg mount 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 mount 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, posing a fundamental durability problem.

The present invention was made in light of the above circumstances, and its purpose is to provide a reel seat that is compatible with both round and low-profile twin-shaft reels, and that not only improves operability by employing a reel seat with a more appropriate offset, but also significantly increases durability while minimizing loss of strength, as well as a fishing rod equipped with the reel seat. Other objects of the present invention will become apparent from reading this entire specification.

A reel seat according to one embodiment of the present invention comprises a reel seat body having a reel leg mounting portion on which a reel leg is placed and a fixed hood provided on one axial side of the reel leg mounting portion, and a movable hood provided on the other axial side of the reel leg mounting portion. The base joint of the fishing rod body is provided on the front side of the reel seat body, and a grip attachment material is provided on the rear side of the reel seat body, both horizontally in the axial direction. The reel leg mounting portion is configured to be offset from a reference position by 2.5 mm to 4.0 mm in the direction opposite the side on which the reel leg is placed, as viewed from the reel leg mounting portion.

A reel seat according to one embodiment of the present invention is a reel seat attached to a fishing rod body, comprising: a reel leg mounting portion on which the reel leg is mounted; a fixed hood provided axially rearward of the reel leg mounting portion; a reel seat body including a partially cut-out cylindrical portion provided axially forward of the reel leg mounting portion; a movable hood provided axially forward of the reel leg mounting portion 12a; and a nut member provided on the outer surface of the cylindrical portion that allows the movable hood to move when rotated. The reel leg mounting portion is configured to be offset from a reference position by 2.5 mm to 4.0 mm in the direction opposite the side on which the reel leg is mounted, as viewed from the reel leg mounting portion.

Embodiments of a reel seat and fishing rod according to the present invention will be described in detail below with reference to the accompanying drawings. Components that are 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 ease of explanation.

Figure 1 shows one embodiment of a fishing rod according to the present invention. As shown, the 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, the reel seat 9 and the fishing line guide 10 each correspond to attachment parts attached to the outer periphery of the rod body.

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.

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 created 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 then polished as appropriate. Each rod body may also be constructed as a solid body.

In the illustrated embodiment, the butt rod 3, middle rod 5, and tip rod 7 are provided with multiple line guides 10 (line guides 10A-10D) that guide the fishing line being 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.

Next, the basic structure of the reel seat body 12 and reel seat 9 will be explained with reference to Figure 2. In the following explanation, the axial direction (front-to-back direction) and up-down direction refer to the directions shown in Figure 2, and the left-to-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 double-bearing reel is attached, and the bottom refers to the opposite side.

The reel seat body 12 has a reel leg mounting 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 slight bulge on the side opposite the reel leg mounting surface 12a, forming a bulge (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 easier to grip. The reel seat body 12 may also be configured so that a fishing rod body is attached to the rear of the reel seat body 12.

The reel leg mounting surface 12a of the reel seat body 12 can be formed flat or approximately flat with a greater curvature than other circumferential portions of the reel seat body 12 adjacent to the reel leg mounting surface 12a (e.g., the trigger 12b), and is formed to extend in the axial direction of the reel seat body 12 as 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.

As will be explained in more detail below, a movable hood 13 is attached to the other end (rod tip side) of the reel seat body 12 so that it can move freely 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 also include other components.

The 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 mounting portion 12a on which the reel leg 6a of a fishing reel 6 is mounted; a fixed hood 14 provided axially rearward of the reel leg mounting portion 12a; a cylindrical portion 15 provided axially forward of the reel leg mounting portion 12a and having a portion cut out; a movable hood 13 provided axially forward 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. The reel leg mounting portion 12a is configured to be offset from a reference position by 2.5 mm to 4.0 mm in the direction opposite the side on which the reel leg 6a is mounted, as viewed from the reel leg mounting 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 mounting portion 12a on which the reel leg 6a is mounted and a fixed hood 14 provided on one axial side of the reel leg mounting portion 12a, and a movable hood 13 provided on the other axial side of the reel leg mounting portion 12a, wherein the base joint 2a of the fishing rod body 2 is mounted on the front side of the reel seat body 12 and a grip attachment material 11 is mounted on the rear side of the reel seat body 12, both of which are horizontal in the axial direction, and the reel leg mounting portion 12a is configured to be offset from a reference position by 2.5 mm to 4.0 mm in the direction opposite the side on which the reel leg 6a is mounted, as seen from the reel leg mounting portion 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 offset, and when the offset is more negative than the reference position, the reel seat is offset (part of the reel is recessed into the reel seat). An offset state means that 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 part of the reel is recessed into the reel seat.

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

In a reel seat 9 according to one embodiment of the present invention, 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.

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

Next, we will explain the thumbing position and offset amount for the reel seat 9 according to one embodiment of the present invention. When a user casts a fishing rod equipped with a reel seat to which a reel is attached, they place their index finger on the trigger, hold the grip with their middle, ring, and little fingers in the palm of their hand, and use their thumb to thumb the reel spool. It has been found that operability is improved 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 is improved 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, and more preferably between 5 mm and 10 mm.

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 at clutch off 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).

As shown in Table 1, when the thumbing height (clutch off position) for each offset amount was checked for five reels, it was 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 the above, it was found that when the offset amount was between -2.5 mm and -4.0 mm, the thumbing height (clutch off position) was the best. 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 and 3.5 mm, the thumbing height (clutch off position) was greater than 12 mm. 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 3.3 mm or less for other reels.

Next, we will explain the results of an operation test on the offset amount of the reel seat 9 according to one embodiment of the present invention. 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)). Ten testers of different genders, ages, and builds evaluated the operability of the fishing rod during actual fishing operations 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 was comfortable to use. Additionally, an overall evaluation was conducted to determine the operability of the fishing rod, including casting, reeling, and lure action.

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 the maximum rating of 10 points. When the offset range was -5.5 mm, although the number of ratings of the maximum rating of 10 points was low, there were many ratings of 7, 8, and 9 points, followed by the next highest performance ratings. On the other hand, when the offset range was -8.5 mm, many ratings were 5 points or less, and the performance ratings were not sufficient. Furthermore, offset ranges 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 it is -2.5 mm to -4.0 mm.

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, as well as a fishing rod equipped with the reel seat.

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, the 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 the 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 partially cut-out tubular portion 15 provided on the axial front side (rod tip side) of the reel leg mounting portion 12a, 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 tubular portion 15 that can be rotated to move the movable hood 13. In the reel 9, the tubular portion 15 has a cylindrical portion 21 and a partially cut-out recessed portion 22, 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 rotation of the nut member 18 allows the movable hood 13 to move axially rearward (toward the butt), 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 this 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. While the tubular portion 15 has been described as having a cylindrical portion 21 and a partially cut-out recessed portion 22, the recessed portion 22 may extend from at least a portion of the inside of the cylindrical portion 21 (i.e., the cylindrical portion 15 has the cylindrical portion 21 on the outside and the recessed portion 22 on at least a portion of the inside).

A reel seat according to one embodiment of the present invention can accommodate both round and low-profile twin-shaft reels, even when a structure is adopted in which the reel leg mounting portion of the reel seat is offset downward relative to the axis of the butt rod, making it possible to provide a reel seat that is strong enough to withstand a decrease in strength and significantly increases durability. More specifically, the rod body itself can be inserted 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 rod body, making it possible to realize a lightweight reel seat structure that is strong enough to accommodate low-profile twin-shaft reels.

2 and 3, a reel seat according to one embodiment of the present invention will be further described. The reel seat body 12 of the reel seat 9 has a cylindrical portion 15 at the front, and a grip portion (rear grip) 23, which is gripped and held, is fixed at the 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 outer surface of the fishing rod body 2 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 that protrudes axially from the rear side of the reel seat body 12, 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 can be a telescopic rod, a jointed rod, a single rod, or any other type of rod, and Figure 2 shows only a portion of the fishing rod (part of the rod body), omitting the entire structure. Also shown is an example in which the reel seat 9 is attached to and fixed to a low-profile dual-bearing reel (hereinafter also referred to as the reel) as the fishing reel 6.

The movable hood 13 includes an engaging portion 16 formed with a male thread, and a hood portion 17 curved radially inward to accommodate at least a portion of the reel leg 6a. The hood portion 17 is arranged to fit into an opening 8 formed below the front end face of the intermediate connecting portion 24 (the end face of the tubular 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 within the opening 8 onto the front end of the reel leg 6a mounted on the reel leg mounting portion 12a.

The male thread of the engaging portion 16 of the movable hood 13 is threadedly engaged with the female thread formed on the inner surface 18a of the nut member 18, which is fitted onto the tubular portion 15 (or the recessed portion 22 of the tubular portion 15). Rotating the nut member 18 in one direction moves the movable hood 13 axially rearward, tightening the front end of the reel leg 6a (reel attachment, fixed state). Rotating the nut member 18 in the other direction moves the movable hood 13 axially forward, releasing the front end of the reel leg 6a (reel removal state). The method of engaging the engaging portion 16 with the inner surface of the nut member 18 can be various conventionally known methods, and is not limited to a specific form (threaded engagement). A circumferential groove is formed around the front end of the tubular portion 15, and a ring-shaped member (retaining ring) 20 can be attached to this groove to prevent the nut member 18 from slipping out forward.

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 onto the grip support portion 25 so that it is flush with the surface of the nut member 18 that is rotated, although a configuration without a grip portion 26 is also possible.

In the reel seat 9 according to one embodiment of the present invention, the engagement portion 16 and the nut member 18 are threadedly engaged.

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

Next, with reference to Figure 5, the cross-sectional structure of a reel seat 9 according to one embodiment of the present invention will be described. Figure 5 shows the A-A cross section of Figure 2. As shown, when the reel seat 9 according to one embodiment of the present invention is in a state in which the fishing rod body 2 is inserted (and the movable hood 13 is in the position shown in Figure 2), and 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 Figure 5), 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 arranged in this order from the inside. As shown, 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.

In this way, the reel seat 9 according to one embodiment of the present invention allows the fishing rod body 2 to be inserted up to the thicker portion of the reel seat body 12 (the cylindrical portion 21 of the tubular section 15 is thicker than the recessed portion 22). This makes it 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, even when a structure is adopted in which the reel leg mounting portion of the reel seat is offset downward relative to the axis of the butt rod.

Next, with reference to Figure 4, the cross-sectional structure of the reel seat 9 according to one embodiment of the present invention will be described. Figure 4 shows the B-B cross section of Figure 2. As shown in the figure, when the reel seat 9 according to one embodiment of the present invention has the fishing rod body 2 inserted (and the movable hood 13 in the position shown in Figure 2), the fishing rod body 2, the reel seat main body 12 (the cylindrical portion 15 or the recessed portion 22), and the nut member 18 are arranged 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 on the plane of Figure 4). When viewed in a cross section perpendicular to the axial direction of the cylindrical portion 15 in a direction downward from the center axis of the cylindrical portion 15 (downward in the vertical direction on the plane of Figure 4), the fishing rod body 2 and the nut member 18 are arranged in this order from the inside, and a space is formed between the fishing rod body 2 and the nut member 18 through which the movable hood 13 passes. In this way, the engagement portion 16 of the movable hood 13 is able to move back and forth in the axial direction of the reel seat 9 through the cutout portion of the recessed portion 22 of the tubular portion 15. 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 comprises a cylindrical portion 21 and a recessed portion 22, and although it does not form a complete cylinder, it can be said to be a tubular portion 15 with a portion cut out (the same applies throughout this specification).

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

Also, as shown in FIG. 6, in the movable hood 13 of a 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). Furthermore, 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. In this way, by adjusting the length of the connecting portion 19, the fishing rod body itself can be inserted up to the portion where the reel seat body has a thick structure.

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.

A fishing rod equipped with a reel seat according to one embodiment of the present invention can accommodate both round and low-profile reels, even when a structure is adopted in which the reel leg mounting portion of the reel seat is offset downward relative to the axis of the butt rod, making it possible to provide a fishing rod equipped with a reel seat that is strong enough to withstand both round and low-profile reels and significantly increases 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 weaker parts can be prevented, making it possible to create an offset reel seat structure with sufficient strength.

In the reel seat 9 according to one embodiment of the present invention, the reel seat body 12 can be formed from carbon fiber reinforced plastic (CFRP), glass reinforced plastic (GFRP), Al, or Mg. The reel seat 12 may also be formed from GFRTP (continuous fiber), GFRTP (discontinuous fiber), CFRTP (continuous fiber), CFRTP (discontinuous fiber), or a hybrid. Forming the reel seat from such materials can ensure sufficient rigidity and strength while minimizing weight increases.

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 top surface of the front region of the intermediate connector 24. The recesses on the first side recess 27 or upper top 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 top 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 figure, 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. Placing the middle finger against the bottom recess 29 to stabilize the fishing reel during casting increases stability and improves casting accuracy. At least one or two of the first side recess 27, second side recess 28, and bottom recess 29 may be provided.

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 fall within 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.
