Description

[Technical Field]

[0001] The present invention relates to a guide frame for a fishing line guide for guiding a fishing line, a fishing line guide, and a fishing rod. [Background technology]

[0002] The fishing line guide described in Patent Document 1 listed below comprises a guide ring 100 and a guide frame 101, as shown in Figure 13. The guide frame 101 has an annular piece 102 that holds the guide ring 100, a pair of left and right side support legs 103 that extend from the annular piece 102 toward the rod tip, and a single rear support leg 104 that extends from the annular piece 102 toward the rod butt. The side support leg 103 has a first attachment portion 105 that is attached to the rod body, and the rear support leg 104 has a second attachment portion 106 that is attached to the rod body. Patent Document 1 explains that because the pair of side support legs 103 are curved in an S-shape when viewed from the side, the side support legs 103 have great resistance to bending, increasing the rigidity of the fishing line guide and reducing flexure.

[0003] However, the rear support leg 104 of this fishing line guide is narrow, and in particular is either roughly the same width as the second attachment portion 106 or gradually narrows toward the second attachment portion 106. Therefore, when the fishing line guide is attached to the fishing rod body, the rear support leg 104 is likely to lack strength, which can cause the rear support leg 104 to twist easily in the circumferential direction of the fishing rod body. In particular, the problem of twisting becomes more pronounced when the rear support leg 104 is long. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 5940738 Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to improve the torsional strength of a guide frame of a fishing line guide. [Means for solving the problem]

[0006] The guide frame of the fishing line guide of the present invention is a guide frame attached to the outer peripheral surface of the rod body for holding a guide ring that guides the fishing line, and comprises: an annular piece for holding the guide ring; a first attachment piece attached to the outer peripheral surface of the rod body; a second attachment piece attached to the outer peripheral surface of the rod body and spaced apart from the first attachment piece in the axial direction of the rod body; a first support piece connecting the annular piece to the first attachment piece; and a second support piece connecting the annular piece to the second attachment piece, and the first support piece has a first extension portion that extends circumferentially around the rod body at a first connection portion that connects to the first attachment piece.

[0007] According to this configuration, a first extension portion is provided at the first connection portion of the first attachment piece. When the fishing line guide is attached to the rod body, the first extension portion reinforces the first attachment piece against twisting in the circumferential direction of the rod body. This suppresses twisting of the first attachment piece. Because the first extension portion reinforces the first attachment piece, even if a large external force is applied to, for example, the annular piece of the fishing line guide in the circumferential direction of the rod body, the first attachment piece is less likely to undergo plastic deformation in the circumferential direction of the rod body. Furthermore, because the first attachment piece is less likely to wobble in the circumferential direction of the rod body during casting, the fishing line and the fishing line guide are less likely to come into contact with each other. This reduces resistance due to this contact, resulting in improved casting distance. Furthermore, the resistance between the fishing line and the fishing line guide is reduced, reducing damage to the fishing line.

[0008] Preferably, the first support piece is shorter than the second support piece. According to this configuration, by providing the first extension portion on the first support piece that is shorter than the second support piece, the torsional strength of the first support piece can be further improved.

[0009] Preferably, the first support piece connects the first support portion of the annular piece that is closest to the outer circumferential surface of the rod body to the first mounting piece. With this configuration, the torsional strength of the first support piece can be further improved by supporting the first support portion that is closest to the outer circumferential surface of the rod body with the first support piece having the first extension portion. Therefore, even if the first support piece is long, sufficient torsional strength can be ensured.

[0010] Preferably, the first support piece has a second connecting portion connected to the annular piece and an intermediate portion provided between the first connecting portion and the second connecting portion, and the first expanding portion is expanded beyond the circumferential width of the rod body at the intermediate portion. With this configuration, the first support piece can be effectively reinforced by the first expanding portion while suppressing an increase in weight of the first support piece.

[0011] Preferably, the width of the first expansion section in the circumferential direction of the rod body gradually increases toward the first attachment piece. With this configuration, the first support piece can be effectively reinforced while suppressing an increase in weight of the first support piece.

[0012] Preferably, the first mounting piece has a second extension portion that extends circumferentially around the rod body at the first mounting end portion that connects to the first support piece. This configuration increases the strength of the first mounting end portion of the first mounting piece and improves the sense of unity from the first extension portion to the second extension portion. This further improves the torsional strength of the first mounting piece.

[0013] Preferably, the second extension section is continuous with the first extension section and has the same width in the circumferential direction of the rod body. This configuration improves the sense of unity from the first extension section to the second extension section, and further improves the torsional strength of the first attachment piece.

[0014] Preferably, the first extension portion has a curved piece that is curved in the circumferential direction of the rod body. With this configuration, when the fishing line guide is attached to the outer circumferential surface of the rod body, the curved piece makes it easier for the first extension portion to fit along the outer circumferential surface of the rod body. Therefore, the fishing line guide can be stably attached to the outer circumferential surface of the rod body.

[0015] Preferably, the first expansion section has a bent piece bent in the axial direction of the rod body. With this configuration, when the fishing line guide is attached to the outer circumferential surface of the rod body, the bent piece reinforces the torsional strength of the first support piece. Furthermore, when an external force acts on the first support piece in the axial direction of the rod body, the bent piece suppresses bending of the first support piece in the axial direction of the rod body.

[0016] Preferably, the second support piece has a pair of arm pieces that connect a pair of second support portions spaced apart in the circumferential direction of the annular piece to the second attachment piece. With this configuration, the pair of arm pieces stably support the annular piece and can prevent the fishing line from getting wrapped around the fishing line guide and becoming tangled.

[0017] A fishing line guide according to the present invention includes the above-mentioned guide frame and a guide ring attached to the annular piece.

[0018] Furthermore, the fishing rod according to the present invention is a fishing rod having a plurality of fishing line guides attached to the outer circumferential surface of the rod body, and the fishing line guides are attached to the fishing line guide that is located furthest toward the butt of the rod, with the first attachment piece facing toward the butt of the rod.

[0019] In addition, the guide frame of the fishing line guide of the present invention is a guide frame that is attached to the outer surface of the rod body and holds a guide ring that guides the fishing line, and is equipped with an annular piece for holding the guide ring, a first attachment piece having a first contact point that contacts the outer surface of the rod body, a second attachment piece that is separated from the first attachment piece in the axial direction of the rod body and has a second contact point that contacts the outer surface of the rod body, a first support piece that connects the annular piece to the first attachment piece, and a second support piece that connects the annular piece to the second attachment piece and is curved radially outward of the rod body, and the first separation distance, which is the shortest distance between an imaginary line passing through the first and second contact points and the inner peripheral edge of the annular piece, is set to be between 1.5 and 2 times the inner diameter of the annular piece.

[0020] A guide ring is attached to the annular piece of the guide frame in this configuration. The guide frame is then attached to the outer periphery of the fishing rod body, for example, with the first attachment piece facing the butt and the second attachment piece facing the tip. An imaginary line passing through the first and second contact points runs along the axial direction of the fishing rod body. The first separation distance, which is the shortest distance between the imaginary line and the inner periphery of the annular piece, is set between 1.5 and 2 times the inner diameter of the annular piece. In other words, the guide ring is far away from the fishing rod body in the radial direction, while its inner diameter is small. In other words, the fishing line guide is long and has a small diameter. This prevents the spiral fishing line released from the reel during casting from coming into contact with the outer periphery of the fishing rod body, thereby increasing casting distance and reducing line trouble. Furthermore, the small diameter of the guide ring allows for a lightweight fishing line guide.

[0021] On the other hand, the second support piece is curved radially outward from the rod body. This prevents the fishing line guide from bending significantly toward the rod tip when the spiral fishing line released from the reel strikes the guide ring. For example, if the second support piece is curved radially inward from the rod body, the fishing line guide is likely to bend significantly toward the rod tip when the spiral fishing line released from the reel strikes the guide ring. To prevent this bending, it becomes necessary to increase the strength of the guide frame, for example, by increasing the thickness of the guide frame. However, increasing the thickness of the guide frame increases the weight of the fishing line guide, which in turn increases the weight of the fishing rod. In contrast, if the second support piece is curved radially outward from the rod body, bending of the fishing line guide can be effectively prevented while suppressing an increase in the weight of the fishing line guide, making it easy to achieve both strength and lightweight for the fishing line guide. This guide frame is particularly suitable for fishing using PE line.

[0022] Furthermore, the fishing line guide of the present invention comprises a guide ring that guides the fishing line, and a guide frame that is attached to the outer circumferential surface of the rod body and holds the guide ring, wherein the guide frame comprises an annular piece for holding the guide ring, a first attachment piece having a first contact point that contacts the outer circumferential surface of the rod body, a second attachment piece that is spaced axially from the first attachment piece and has a second contact point that contacts the outer circumferential surface of the rod body, a first support piece that connects the annular piece to the first attachment piece, and a second support piece that connects the annular piece to the second attachment piece and is curved radially outward of the rod body, and wherein a second separation distance, which is the shortest distance between an imaginary line passing through the first and second contact points and the inner circumferential edge of the guide ring, is set to be between two and three times the inner diameter of the guide ring.

[0023] A fishing line guide of this configuration is attached to the outer periphery of the fishing rod body, for example, with the first attachment piece facing toward the butt and the second attachment piece facing toward the tip. An imaginary line passing through the first and second contact points runs along the axial direction of the fishing rod body. The second separation distance, which is the shortest distance between the imaginary line and the inner periphery of the guide ring, is set between two and three times the inner diameter of the guide ring. In other words, the guide ring is far away from the fishing rod body in the radial direction, while the inner diameter of the guide ring is small. In other words, the fishing line guide is long and has a small diameter. This prevents the spiral fishing line released from the reel during casting from coming into contact with the outer periphery of the fishing rod body, thereby increasing casting distance and reducing line trouble in the fishing line guide. Furthermore, the small diameter of the guide ring allows for a lightweight fishing line guide.

[0024] On the other hand, the second support piece is curved radially outward from the rod body. This prevents the fishing line guide from bending significantly toward the rod tip when the spiral fishing line released from the reel strikes the guide ring. For example, if the second support piece is curved radially inward from the rod body, the fishing line guide is likely to bend significantly toward the rod tip when the spiral fishing line released from the reel strikes the guide ring. To prevent this bending, it becomes necessary to increase the strength of the guide frame, for example, by increasing the thickness of the guide frame. However, increasing the thickness of the guide frame increases the weight of the fishing line guide, which in turn increases the weight of the fishing rod. In contrast, if the second support piece is curved radially outward from the rod body, bending of the fishing line guide can be effectively prevented while suppressing an increase in the weight of the fishing line guide, making it easy to achieve both strength and lightweight for the fishing line guide. This fishing line guide is particularly suitable for fishing using PE line. [Effects of the Invention]

[0027] A guide frame for a fishing line guide according to one embodiment of the present invention, a fishing line guide using the guide frame, and a fishing rod equipped with the fishing line guide will be described below with reference to FIGS. 1 to 9. As shown in FIG. 7, the fishing line guide 1 includes a guide frame 2 attached to the outer periphery of the fishing rod body 4 and a guide ring 3 attached to the guide frame 2 for directly guiding the fishing line 5. The fishing line guide 1 is fixed to a predetermined position on the outer periphery of the fishing rod body 4. The fishing line guide 1 is used by attaching it to various fishing rods to which a reel can be attached, but is particularly suitable for fishing rods used for casting and lure fishing. As will be described later, the fishing line guide 1 of this embodiment is suitable for the fishing line guide 1 located furthest toward the butt of multiple fishing line guides 1 attached to a fishing rod, i.e., the butt guide 1a, but it can also be used for fishing line guides 1 attached in other positions.

[0028] In the following description, the axial direction (center line direction) of the rod body 4 is referred to as the front-to-rear direction, the rod tip direction is referred to as the front direction and is indicated by arrow X2 in the drawings, and the rod butt direction is referred to as the rear direction and is indicated by arrow X1 in the drawings. Furthermore, of the radial directions of the rod body 4, the direction radially away from the outer circumferential surface of the rod body 4 toward the attachment direction of the reel is referred to as the first radial direction and is indicated by arrow Z1 in the drawings, and the opposite direction, approaching the outer circumferential surface of the rod body 4, is referred to as the second radial direction and is indicated by arrow Z2 in the drawings. Furthermore, the circumferential direction of the rod body 4, which is perpendicular to (intersects with) the first radial direction Z1 and the second radial direction Z2, is referred to as the left-to-right direction and is indicated by arrow Y in the drawings.

[0029] <Guide frame 2> 1 to 5 show the guide frame 2 in this embodiment. The guide frame 2 is made of metal and consists of a single metal plate. That is, the guide frame 2 is a one-piece unit made of sheet metal. Therefore, the guide frame 2 is composed of a single member. The guide frame 2 is formed by punching a single metal plate into a predetermined shape and bending the flat metal plate punched into the predetermined shape. The metal plate used has a constant thickness, for example, about 1 mm. The material is, for example, stainless steel or titanium (titanium alloy).

[0030] The guide frame 2 comprises an annular piece 10, a first support piece 11, a second support piece 12 having a pair of left and right arm pieces 13, a first attachment piece 14, and a second attachment piece 15. The annular piece 10 holds the guide ring 3. The first support piece 11 connects the annular piece 10 and the first attachment piece 14. The second support piece 12 connects the annular piece 10 and the second attachment piece 15. The first attachment piece 14 and the second attachment piece 15 are both attached to the outer circumferential surface of the rod body 4.

[0031] <Annular piece 10> The annular piece 10 has a ring mounting hole 20. The guide ring 3 is mounted in the ring mounting hole 20. The hole center line 20a of the ring mounting hole 20 coincides with the center line of the guide ring 3. The hole center line 20a of the ring mounting hole 20 may be aligned with the front-rear direction, but is preferably inclined at a predetermined angle relative to the front-rear direction, as shown in FIG. 3. In FIG. 3, a virtual center line 20b is a straight line in the front-rear direction passing through the center of the ring mounting hole 20. The first inclination angle α1 of the hole center line 20a of the ring mounting hole 20 relative to the front-rear direction is preferably greater than 0 degrees and less than 20 degrees, more preferably greater than 0 degrees and less than 5 degrees, and even more preferably greater than 1 degree and less than 5 degrees, where 0 degrees is the angle of the hole center line 20a of the ring mounting hole 20 aligned with the front-rear direction. The annular piece 10 may be flat, or may be drawn into a cylindrical shape along the center line 20a of the ring mounting hole 20. The inner peripheral edge 10a of the annular piece 10 is the wall surface of the ring mounting hole 20. A first plane 10c defined by the annular piece 10 is inclined at a predetermined angle toward the forward direction X2 with respect to a second plane 10d that is perpendicular to the axial direction of the rod body 4. The second inclination angle α2 of the first plane 10c with respect to the second plane 10d is equal to the first inclination angle α1. The first inclination angle α1 and the second inclination angle α2 are related to the bending angle θ, which will be described later.

[0032] The annular piece 10 has a first support portion 21 supported by the first support piece 11 and a pair of left and right second support portions 22 supported by the pair of left and right arm pieces 13, respectively. The first support portion 21 is the portion of the entire circumference of the annular piece 10 that is located closest to the second radial direction Z2. In other words, the first support portion 21 is the portion of the entire circumference of the annular piece 10 that is closest to the outer circumferential surface of the rod body 4. The pair of second support portions 22 are spaced apart from each other in the circumferential direction of the annular piece 10. The pair of second support portions 22 are symmetrical to each other. The first support portion 21 is located between the pair of second support portions 22. The pair of second support portions 22 are located further in the first radial direction Z1 than the first support portion 21. In other words, the pair of second support portions 22 are farther from the outer circumferential surface of the rod body 4 than the first support portions 21. The pair of second support portions 22 are preferably located in the first radial direction Z1 farther from the center of the annular piece 10 (the center of the ring mounting hole 20), and are preferably farther from the outer circumferential surface of the rod body 4.

[0033] <First support piece 11> The first support piece 11 extends from the first support portion 21 of the annular piece 10 toward the first mounting piece 14. The first support piece 11 extends from the first support portion 21 of the annular piece 10 toward the second radial direction Z2, preferably extending while inclining in the second radial direction Z2 and the rearward direction X1. The first support piece 11 connects the first support portion 21 of the annular piece 10 to the first mounting piece 14. The first support piece 11 is preferably a flat, uncurved surface, and is preferably parallel to the guide ring 3. The thickness direction of the first support piece 11 is the direction of the hole center line 20a of the ring mounting hole 20. The first support piece 11 may be aligned along the radial direction of the outer circumferential surface of the rod body 4, but is preferably inclined toward the forward direction X2 with respect to the radial direction of the rod body 4, as in this embodiment. As shown in FIG. 3, the first support piece 11 is preferably flush with the annular piece 10. That is, the first support piece 11 is located on the first flat surface 10c. The first support piece 11 is inclined at a second inclination angle α2 in the forward direction X2 with respect to the second plane 10d.

[0034] The first support piece 11 may have various shapes in a front view when viewed along the direction of the hole center line 20a of the ring mounting hole 20 (the plate thickness direction of the first support piece 11). The first support piece 11 has a first connection portion 30 that connects to the first mounting piece 14 and a second connection portion 31 that connects to the annular piece 10.

[0035] The first support piece 11 has a first extension portion 32 at the first connection portion 30, a third extension portion 33 at the second connection portion 31, and an intermediate portion 34 between the first connection portion 30 and the second connection portion 31. The first extension portion 32 is a portion whose width in the left-right direction is locally expanded. FIG. 6 shows a main portion of the guide frame 2 in a flat state before being folded. In FIG. 6, a folding line 35 between the first support piece 11 and the first mounting piece 14 is indicated by a dashed line. The left-right width W1 of the first extension portion 32 gradually increases toward the first mounting piece 14. The left-right width W1 of the first extension portion 32 may increase linearly or curve toward the first mounting piece 14. The first extension portion 32 has a symmetrical shape.

[0036] The left-right width W1 of the first extension portion 32 is wider than the left-right width W2 of the intermediate portion 34. The intermediate portion 34 is the portion of the first support piece 11 that has the narrowest left-right width. The intermediate portion 34 preferably has an elongated shape along the direction connecting the first support portion 21 of the annular piece 10 and the first mounting piece 14, and preferably has a constant left-right width.

[0037] The first support piece 11 has a third expansion portion 33 at the second connection portion 31. The third expansion portion 33 is a portion whose width in the left-right direction is locally expanded. The left-right width of the third expansion portion 33 is wider than the left-right width W2 of the middle portion 34. The left-right width of the third expansion portion 33 gradually increases toward the annular piece 10. The left-right width of the third expansion portion 33 may increase linearly or curvedly toward the annular piece 10. Note that the third expansion portion 33 may be provided with a through-hole (not shown) that penetrates through the plate thickness direction, and the third expansion portion 33 may have a V-shaped shape that widens toward the annular piece 10.

[0038] <First mounting piece 14> The first mounting piece 14 extends from the first connection portion 30 of the first support piece 11 toward the rear direction X1. The first mounting piece 14 is bent at a predetermined angle relative to the first support piece 11. The first mounting piece 14 may be bent at a bending angle θ of 90 degrees relative to the first support piece 11, but is preferably bent at a bending angle θ of less than 90 degrees. In other words, the first support piece 11 is preferably inclined toward the second support piece 12 and the second mounting piece 15. The bending angle θ is preferably equal to or greater than 85 degrees and less than 90 degrees. Note that when the bending angle θ is, for example, 85 degrees, the first inclination angle α1 and the second inclination angle α2 are both 5 degrees.

[0039] The first mounting piece 14 has a long shape extending in the front-to-rear direction. The first mounting piece 14 has a first mounting end 40 that connects to the first support piece 11 and a second mounting end 41 that is located in the opposite front-to-rear direction to the first mounting end 40. The first mounting end 40 is the end of the first mounting piece 14 in the front direction X2, and the second mounting end 41 is the end of the first mounting piece 14 in the rear direction X1. The second mounting end 41 is a free end. The first mounting piece 14 has a base portion 43 and a second extension portion 42 that is provided on the first mounting end 40 and is wider in the left-to-right direction than the base portion 43.

[0040] The second expansion portion 42 is a portion whose width in the left-right direction is locally expanded. The left-right width W3 of the second expansion portion 42 gradually increases toward the first support piece 11. The left-right width W3 of the second expansion portion 42 may increase linearly or curvedly toward the first mounting piece 14. The second expansion portion 42 has a symmetrical shape.

[0041] The left-right width W3 of the second extension portion 42 is continuous with the left-right width W1 of the first extension portion 32. The left-right width W3 (maximum width) of the second extension portion 42 is the same as the left-right width W1 (maximum width) of the first extension portion 32. The left-right width W3 of the second extension portion 42 is wider than the left-right width W4 of the base portion 43.

[0042] It is preferable that the first opposing surface 14a of the first mounting piece 14, which faces the outer peripheral surface of the rod body 4, is curved in the left-right direction toward the first radial direction Z1 so as to fit along the outer peripheral surface of the rod body 4. Also, the first expansion section 32 and the second expansion section 42 may be continuously curved in the front-rear direction.

[0043] The first opposing surface 14a has a first contact point 14b that contacts the outer circumferential surface of the rod body 4. The first contact point 14b is located on a first center line 14c that extends along the front-rear direction of the first opposing surface 14a. The first center line 14c is a straight line that bisects the width of the first opposing surface 14a.

[0044] <Second support piece 12, arm piece 13> The arm piece 13 extends from the second support portion 22 of the annular piece 10 toward the second mounting piece 15. The arm piece 13 connects the second support portion 22 of the annular piece 10 to the second mounting piece 15. The arm piece 13 has a third connection portion 50 that connects to the third mounting end portion 60 of the second mounting piece 15 and a fourth connection portion 51 that connects to the second support portion 22 of the annular piece 10. The pair of left and right arm pieces 13 are symmetrical in shape to each other in the left-right direction. The arm pieces 13 as a whole extend from the second support portion 22 of the annular piece 10 while inclining in the second radial direction Z2 and the forward direction X2. The arm piece 13 curves in the first radial direction Z1 with respect to a straight line 52 that connects the second support portion 22 of the annular piece 10 to the third mounting end portion 60 of the second mounting piece 15. The arm piece 13 extends from the second support portion 22 of the annular piece 10 toward the forward direction X2 and then toward the second radial direction Z2. The pair of arm pieces 13 gradually approach each other toward the second mounting piece 15. The arm pieces 13 are longer than the first support piece 11. The arm pieces 13 are thinner than the first support piece 11.

[0045] <Second mounting piece 15> The second mounting piece 15 is spaced apart from the first mounting piece 14 in the forward direction X2. The direction connecting the first mounting piece 14 and the second mounting piece 15 is the front-to-rear direction. The first mounting piece 14 is located in the rear direction X1 relative to the annular piece 10, and the second mounting piece 15 is located in the forward direction X2 relative to the annular piece 10.

[0046] The second mounting piece 15 extends from the third connection portion 50 of the arm piece 13 in the forward direction X2. The second mounting piece 15 is bent at a predetermined angle relative to the arm piece 13. The second mounting piece 15 has a long shape along the front-rear direction. The second mounting piece 15 has a third mounting end 60 that connects to the pair of arm pieces 13 and a fourth mounting end 61 located opposite the third mounting end 60 in the front-rear direction. The third mounting end 60 is the end of the first mounting piece 14 in the rear direction X1, and the fourth mounting end 61 is the end of the first mounting piece 14 in the front direction X2. The fourth mounting end 61 is a free end. The width of the second mounting piece 15 in the left-right direction is approximately constant. Note that the second opposing surface 15a of the second mounting piece 15 that faces the outer circumferential surface of the rod body 4 is preferably curved along the left-right direction toward the first radial direction Z1 so as to fit along the outer circumferential surface of the rod body 4.

[0047] The second opposing surface 15a has a second contact point 15b that contacts the outer circumferential surface of the rod body 4. The second contact point 15b is located on a second center line 15c that extends along the front-rear direction of the second opposing surface 15a. The second center line 15c is a straight line that bisects the width of the second opposing surface 15a.

[0048] <Guide ring 3> The guide ring 3 is typically circular, but may also be elliptical or oblong. In this embodiment, the guide ring 3 is circular. The guide ring 3 is preferably attached to the annular piece 10 by adhesive. The guide ring 3 is inserted into the ring mounting hole 20 in the forward direction X2.

[0049] 1 to 3, 5, and 7 show an imaginary line 16 passing through the first contact point 14b and the second contact point 15b. The imaginary line 16 is aligned along the axial direction of the rod body 4 and is located on the outer circumferential surface of the rod body 4. A first distance L1, which is the shortest distance between the imaginary line 16 and the inner peripheral edge 10a of the annular piece 10, is set to be between 1.5 and 2 times the inner diameter 10b of the annular piece 10. The first distance L1 is preferably 1.7 times the inner diameter 10b of the annular piece 10. The first distance L1 is the radial distance of the rod body 4 between the first opposing surface 14a and the portion of the inner peripheral edge 10a of the annular piece 10 closest to the rod body 4, i.e., closest to the first opposing surface 14a. A second distance L2, which is the shortest distance between the imaginary line 16 and the inner peripheral edge 3a of the guide ring 3, is set to be between 2 and 3 times the inner diameter 3b of the guide ring 3. The second separation distance L2 is preferably 2.4 times the inner diameter 3b of the guide ring 3. The second separation distance L2 is the separation distance in the radial direction of the rod body 4 between the part of the inner peripheral edge 3a of the guide ring 3 that is closest to the rod body 4 and the first opposing surface 14a.

[0050] <Installation state> As shown in Figure 7, the fishing line guide 1 is attached and fixed to the outer circumferential surface of the fishing rod body 4. The attachment method is, for example, by applying a wound line and adhesive. The fishing line guide 1 is preferably attached to the outer circumferential surface of the fishing rod body 4 with the second attachment piece 15 facing forward in the X2 direction and the first attachment piece 14 facing backward in the X1 direction. However, the fishing line guide 1 may also be attached in the reversed front-to-back direction. When the fishing line guide 1 is attached to the fishing rod body 4, the guide ring 3 is inclined in the forward direction X2 at a second inclination angle α2.

[0051] When a spinning reel 6 is used, the spinning reel 6 is normally positioned downward relative to the rod body 4, and the fishing line guide 1 is positioned below the rod body 4. When a dual-bearing reel (not shown) is used, the dual-bearing reel is normally positioned above the rod body 4, and the fishing line guide 1 is positioned above the rod body 4. In this way, the fishing line guide 1 is positioned in the same direction as the reel relative to the rod body 4. The fishing line guide 1 in this embodiment is suitable for a fishing rod that uses a spinning reel 6.

[0052] FIG. 8 shows a fishing rod suitable for use with a spinning reel 6. FIG. 9 shows the fishing rod of FIG. 8 with the spinning reel 6 attached in use. The fishing rod includes a rod body 4, multiple fishing line guides 1 attached at intervals to the outer periphery of the rod body 4, and a reel seat 7 for attaching the spinning reel 6. The multiple fishing line guides 1 are composed of a top guide 1b located furthest forward in the X2 direction, a base guide 1a located furthest rearward in the X1 direction, and multiple intermediate guides 1c located between the top guide 1b and the base guide 1a. The fishing line guide 1 of this embodiment is suitable for use as the base guide 1a (butt guide). The base guide 1a is the fishing line guide 1 located furthest rearward in the X1 direction among the multiple fishing line guides 1. The above-described fishing line guide 1 is used for at least the base guide 1a among the multiple fishing line guides 1. The above-described fishing line guide 1 can be used for fishing line guides 1 other than the top guide 1b.

[0053] As described above, the first extension portion 32 is locally provided on the first connection portion 30 of the first attachment piece 14, making it difficult for the first attachment piece 14 to twist left and right. For example, even if a large external force acts in the left and right direction on the annular piece 10 of the fishing line guide 1, the first attachment piece 14 is unlikely to deform left and right. During casting, the first attachment piece 14 is unlikely to wobble left and right, reducing the resistance between the fishing line 5 and the fishing line guide 1 and improving casting distance. Furthermore, damage to the fishing line 5 is also reduced.

[0054] In particular, first extension portion 32 is provided on first support piece 11, which is shorter than second support piece 12, which effectively prevents twisting of fishing line guide 1. First support piece 11 connects first support portion 21 of annular piece 10 to first mounting piece 14, which further improves the torsional strength of first support piece 11, and even if first support piece 11 is longer, sufficient torsional strength of fishing line guide 1 can be ensured.

[0055] When the second support piece 12 has a pair of left and right arm pieces 13, the annular piece 10 can be stably supported by the pair of arm pieces 13, and vibration of the annular piece 10 in the front-to-rear direction can be suppressed. In particular, when the arm pieces 13 are curved in the first radial direction Z1 as shown in FIG. 3, deflection of the annular piece 10 in the rear direction X1 can be suppressed. Furthermore, when the second support portion 22 supported by the arm pieces 13 is positioned further in the first radial direction Z1 than the center of the ring mounting hole 20, the annular piece 10 can be effectively supported by the arm pieces 13, and deflection of the annular piece 10 in the front-to-rear direction can be effectively suppressed.

[0056] If the width W1 in the left-right direction of the first extension portion 32 is wider than the width W2 in the left-right direction of the intermediate portion 34, the first extension portion 32 can effectively reinforce the vicinity of the first connection portion 30 of the first support piece 11 while suppressing an increase in weight of the first support piece 11. In particular, if the width W1 in the left-right circumferential direction of the first extension portion 32 gradually increases toward the first mounting piece 14, the vicinity of the connection portion of the first support piece 11 can be effectively reinforced while suppressing an increase in weight of the first support piece 11.

[0057] Providing the second extension portion 42 at the first mounting end 40 of the first mounting piece 14 increases the strength of the first mounting end 40 of the first mounting piece 14. This also improves the sense of unity from the first extension portion 32 to the second extension portion 42. This makes the first mounting piece 14 even more resistant to twisting. In particular, if the second extension portion 42 is continuous with the first extension portion 32 and the left-right width W3 of the second extension portion 42 is the same as the left-right width W1 of the first extension portion 32, this improves the sense of unity from the first extension portion 32 to the second extension portion 42, making the first mounting piece 14 even more resistant to twisting. If the left-right width W3 of the second extension portion 42 is wider than the left-right width W4 of the base portion 43, the torsional strength of the first extension portion 32 can be improved via the second extension portion 42, and an increase in the weight of the first mounting piece 14 can be suppressed.

[0058] If the first support piece 11 is a flat surface that is not curved, it is possible to prevent the line from becoming tangled in the first expansion portion 32. Therefore, it is preferable that the first support piece 11 bends relative to the first attachment piece .

[0059] The first distance L1 is set between 1.5 and 2 times the inner diameter 10b of the annular piece 10. The second distance L2 is set between 2 and 3 times the inner diameter 3b of the guide ring 3. In other words, the guide ring 3 is far away from the fishing rod body 4 in the first radial direction Z1, while the inner diameter 3b of the guide ring 3 is small. The base guide 1a is long and has a small diameter. The fishing line 5 released from the reel 6 during casting spirals toward the base guide 1a. Because the first distance L1 is set between 1.5 and 2 times the inner diameter 10b of the annular piece 10, and the second distance L2 is set between 2 and 3 times the inner diameter 3b of the guide ring 3, the spiral fishing line 5 released from the reel 6 is less likely to come into contact with the outer periphery of the fishing rod body 4. This increases the casting distance and reduces line trouble in the base guide 1a. Furthermore, because the guide ring 3 of the base guide 1a has a small diameter, the base guide 1a can be made lighter, and the fishing rod can be made lighter.

[0060] On the other hand, the second support piece 12 is curved toward the first radial direction Z1 of the rod body 4. Therefore, when the spiral fishing line 5 released from the reel 6 hits the guide ring 3 of the base guide 1a, the base guide 1a can be prevented from bending significantly in the forward direction X2. For example, if the second support piece 12 were curved toward the second radial direction Z2 of the rod body 4, the spiral fishing line 5 released from the reel 6 would hit the guide ring 3 of the base guide 1a, causing the base guide 1a to bend significantly in the forward direction X2. To prevent this bending, it would be necessary to increase the strength of the guide frame 2, for example, by increasing the thickness of the guide frame 2. However, increasing the thickness of the guide frame 2 would increase the weight of the base guide 1a and the fishing rod. In contrast, if the second support piece 12 is curved toward the first radial direction Z1 of the rod body 4, bending of the base guide 1a can be effectively suppressed, and an increase in the weight of the base guide 1a can be suppressed, making it easy to achieve both strength and light weight for the base guide 1a. It is especially suitable for fishing using PE line.

[0061] 10(a), the first mounting piece 14 may not be provided with the second extension portion 42, but may instead be provided with a base portion 43 of a constant width over the entire length of the first mounting piece 14. In this case, the left-right width W4 of the base portion 43 becomes the left-right width W5 of the first mounting piece 14, and the left-right width W5 of the first mounting piece 14 is narrower than the left-right width W1 of the first extension portion 32.

[0062] 10(b), the first expansion section 32 may have a curved piece 70 curved along the circumferential direction of the rod body 4. A third opposing surface 70a of the curved piece 70 that faces the outer peripheral surface of the rod body 4 (the end surface facing the outer peripheral surface of the rod body 4) is curved in the first radial direction Z1 along the circumferential direction of the rod body 4. Therefore, when the fishing line guide 1 is attached to the outer peripheral surface of the rod body 4, the third opposing surface 70a of the curved piece 70 easily fits along the outer peripheral surface of the rod body 4, and the fishing line guide 1 can be stably attached to the outer peripheral surface of the rod body 4.

[0063] 11(a), the width W5 in the left-right direction of the first mounting piece 14 may be the same as the width W1 in the left-right direction of the first extension portion 32 over substantially the entire length. Alternatively, as shown in FIG. 11(b), the first extension portion 32 may have a bent piece 80 bent toward the forward direction X2. A pair of left and right bent pieces 80 is preferably provided. The pair of left and right bent pieces 80 is preferably symmetrical to each other. The bent piece 80 is preferably bent toward the forward direction X2 at a bending angle of less than 90 degrees relative to the first support piece 11, and the bending angle may be, for example, 45 degrees. In this way, it is preferable that the bent piece 80 is inclined toward the forward direction X2 relative to the first support piece 11. The bent piece 80 suppresses twisting of the first support piece 11, and the bent piece 80 also functions as a tension member to suppress bending of the first support piece 11 in the forward direction X2.

[0064] 12, the second mounting piece 15 may have a pair of arm extensions 90 formed by extending the pair of arm pieces 13. The pair of left and right arm extensions 90 are joined together in the left-right direction to form the second mounting piece 15. The pair of arm extensions 90 are continuous with each other at the fourth mounting end 61 and are folded back. [Explanation of symbols]
