Description

  The present invention relates to a fishing rod and a rod having a solid rod.

  In the fishing rod of Patent Document 1 below, a prepreg is wound around the outside of a solid body. The reinforcing fibers of the prepreg are so-called longitudinal fibers along the direction of the center line of the solid body. This longitudinal fiber is effective for bending strength. On the other hand, since the space between the longitudinal fibers is a resin, cracks are likely to occur between the longitudinal fibers.

JP 2001-136869 A

  An object of the present invention is to provide a fishing rod and a rod body that can suppress generation of cracks.

  The fishing rod according to the present invention includes a solid rod body, and the blank of the rod body is a cylindrical main layer including a solid body having the entire length of the blank and a prepreg formed outside the solid body. The main layer comprises a longitudinal fiber prepreg layer formed over the entire length of the main layer from a prepreg in which the reinforcing fibers are in the direction of the center line of the rod body, and a prepreg composed of a woven fabric of the reinforcing fibers. A woven prepreg layer formed over the entire length of the layer.

  Reinforcing fibers along the direction of the centerline of the rod are referred to as longitudinal fibers. The main layer of the solid rod body blank of the fishing rod has a longitudinal fiber prepreg layer made of longitudinal fiber prepreg and a woven fabric prepreg layer made of reinforced fiber prepreg. Both the warp fiber prepreg layer and the woven prepreg layer are formed over the entire length of the main layer. The bending strength can be ensured by the longitudinal fiber prepreg layer formed over the entire length of the main layer. And the generation of cracks between longitudinal fibers can be suppressed by the woven prepreg layer formed over the entire length of the main layer.

  In particular, the longitudinal fiber prepreg layer and the woven fabric prepreg layer are a laminated sheet in which the first sheet in which the reinforcing fibers are in the direction of the center line of the rod body and the second sheet made of the woven fabric of the reinforcing fibers are laminated. Is preferably formed. By using such a laminated sheet, a prepreg made of a woven fabric of reinforcing fibers can be easily wound over the entire length of the main layer. Further, by using the laminated sheet, the woven fabric prepreg layer can be adjacent to the warp fiber prepreg layer. Therefore, the generation of cracks in the warp fiber prepreg layer can be suppressed by the adjacent woven fabric prepreg layer. When the laminated sheet is wound over one turn (1 ply) partially or over the entire length, the generation of cracks in the longitudinal fiber prepreg layer can be further suppressed, and the inside of the cracks can be prevented. Progress can also be suppressed.

  Further, the prepreg layer formed from the laminated sheet is the outermost prepreg layer of the main layer, and the main layer is formed from a prepreg shorter than the entire length of the main layer inside the prepreg layer formed from the laminated sheet. It is preferable to have one or more prepreg layers. Cracks that easily occur on the outer peripheral surface of the main layer when the rod body is bent can be effectively suppressed by the woven prepreg layer in the outermost prepreg layer. Also, by having one or more prepreg layers made of a prepreg shorter than the entire length of the main layer inside the prepreg layer made of the laminated sheet, it is possible to prevent the solid body from becoming excessively thick, and to form a blank. Can be reduced in weight.

  Further, the reinforcing fibers of one or more prepreg layers formed from a prepreg shorter than the entire length of the main layer are preferably along the direction of the center line of the rod body. One or more vertical fiber prepreg layers formed from vertical fiber prepregs shorter than the entire length of the main layer, and the vertical fiber prepreg layers formed over the entire length of the main layer facilitate bending strength of the blank of the rod body. Can be secured. And the generation of a crack between longitudinal fibers can be suppressed by the woven prepreg layer.

  Further, the solid body has a front part whose diameter is increased toward the rear side at a predetermined taper rate, and a rear part whose diameter is expanded toward the rear side with a taper rate smaller than the taper rate of the front part or has a constant diameter. The main layer is formed over the entire length of the solid body, and the main layer is formed on the inside of the warp fiber prepreg layer and the woven prepreg layer by a plurality of prepregs shorter than the entire length of the main layer. Prepreg layers, the rear ends of the plurality of prepreg layers are respectively located at the rear ends of the solid bodies, and the front ends of the plurality of prepreg layers are positioned closer to the outer prepreg layers. Is preferred. By making the taper ratio of the rear part of the solid body smaller than that of the front part, the weight of the solid body can be reduced. The tone of the rod can be set by the main layer, and particularly, the tone of the rear part of the rod can be easily set by the main layer. Further, by winding a prepreg shorter than the entire length of the main layer mainly on the rear portion of the solid body inside the warp fiber prepreg layer and the woven fabric prepreg layer, the taper ratio at the rear portion of the blank gradually increases. Can be approached. Therefore, the prepreg for forming the warp fiber prepreg layer and the prepreg for forming the woven fabric prepreg layer can be neatly wound.

  In addition, the reinforcing fibers of the woven fabric are preferably along the direction of the center line of the rod body and the circumferential direction of the rod body, and the generation of cracks due to the longitudinal fibers can be effectively suppressed.

  Further, the fishing rod according to the present invention has a solid first rod body having a spike at the front end and a male joint at the rear end, and a male joint of the first rod at the front end. It has a female side joint part that is detachably inserted, and has a hollow second rod body having a rod bottom at the rear end, and the blank of the first rod body has the entire length of the blank. A solid body and a cylindrical main layer made of a prepreg formed outside the solid body, wherein the main layer extends from the prepreg where the reinforcing fiber is along the center line direction of the rod to the entire length of the main layer. And a woven prepreg layer formed over the entire length of the main layer from a prepreg made of a woven fabric of reinforcing fibers.

  The fishing rod of this configuration is composed of two rods, a first rod on the front side and a second rod on the rear side. By making the first rod body on the front side solid, it is possible to give a sticky tone, and by making the second rod body on the rear side hollow, the fishing rod can be prevented from becoming too heavy. Weight.

  Preferably, the first rod body includes all the fishing line guides of the fishing rod, and the second rod body includes a reel sheet. The first rod body can provide a viscous tone to near the hand, and can provide a tone close to a one-piece rod. Moreover, by making the second rod body having the reel seat hollow, the weight of the fishing rod can be reduced. Further, since the first rod body is provided with all the fishing line guides, for example, it is also possible to use the second rod body by attaching a first rod body of another specification. That is, the first rod body and the second rod body can be appropriately combined and used.

  Further, the rod body of the fishing rod according to the present invention is a solid rod body, and the blank of the rod body is composed of a solid body having the entire length of the blank and a prepreg formed outside the solid body.

The configuration of the fishing rod is arbitrary, and may be a one-piece rod or a swing rod, but in the present embodiment, it is a double-spliced configuration. The fishing rod of the present embodiment is composed of two rod bodies, a first rod body 1 constituting a front part of the fishing rod and a second rod body 2 constituting a rear part of the fishing rod. FIG. 1 shows a state where the first rod body 1 and the second rod body 2 are separated, and FIG. 2 shows a state where the first rod body 1 and the second rod body 2 are connected and joined together. .

  The first rod 1 is solid, and the second rod 2 is hollow. The first rod body 1 has a solid blank 10, and the second rod body 2 has a hollow blank 20. The first rod body 1 occupies most of the length of the fishing rod and constitutes a main part of the fishing rod. The first rod body 1 has a length exceeding at least half of the entire length of the fishing rod. That is, the first rod 1 is longer than the second rod 2. The first rod body 1 has a tip portion of a fishing rod at a front end portion, and has a male joint portion 11 at the rear end portion for joining with the second rod body 2. The second rod body 2 has a female joint 21 at the front end for joining with the first rod body 1, and has a rod end of a fishing rod at the rear end. The male joint 11 of the first rod 1 is removably inserted into the female joint 21 of the second rod 2. The joining method between the first rod 1 and the second rod 2 is parallel joining. Therefore, the first rod body 1 is joined to the front side of the second rod body 2 by frictional resistance between the outer peripheral surface of the male joint part 11 and the inner peripheral surface of the female joint part 21. However, the joining method may be various.

  The first rod body 1 includes all the fishing line guides 3 of the fishing rod. Therefore, the second rod body 2 does not include the fishing line guide 3. The second rod body 2 has a reel seat 4 near the front end thereof. A double-axis reel is attached to the reel sheet 4. Although the configuration of the reel sheet 4 is arbitrary, the present embodiment has a trigger 5 on the lower surface. The reel sheet 4 has a cylindrical shape and is bonded and fixed to the outside of the blank 20 of the second rod body 2 directly or via a cylindrical spacer. The reel seat 4 is a reel seat 4 having a so-called front lock structure including a movable hood 6 and a nut 7 for moving the movable hood 6 on the front side. In the separated state as shown in FIG. 1, the nut 7 and the movable hood 6 can be removed from the front end of the second rod body 2 to the front side.

  The second rod body 2 has grip portions 22 and 23 on the rear side of the reel sheet 4. The grip portions 22 and 23 are made of a grip material such as foamed EVA or cork, for example, and are adhered and fixed to the outside of the blank 20. The grip portions 22 and 23 are provided at two front and rear portions, and have a first grip portion 22 on the front side and a second grip portion 23 on the rear side. The first grip portion 22 is located immediately after the reel sheet 4. The second grip portion 23 is located away from the first grip portion 22 on the rear side, and is located at the rear end of the second rod body 2. Note that only one grip portion 22, 23 may be provided. The female joint 21 of the second rod body 2 is constituted by a predetermined length region of the front end of the blank 20. Most of the female joint 21 is located inside the reel seat 4. Accordingly, the first rod 1 is joined to the second rod 2 inside the reel sheet 4. The blank 20 of the second rod body 2 is formed by winding a prepreg around a mandrel.

  FIG. 3 shows the entire blank 10 of the first rod body 1, FIG. 4 shows a partial perspective view of the blank 10, and FIG. 5 schematically shows the configuration of the blank 10 and the manufacturing process thereof.

And a coating layer 34 formed on the outside of the cross tape layer 32 as shown by a chain line.

<Solid body 30>
The solid body 30 is made of a fiber-reinforced resin, and as the reinforcing fiber, for example, glass fiber or carbon fiber is used, and preferably carbon fiber. The reinforcing fibers of the solid body 30 are so-called longitudinal fibers along the direction of the center line of the solid body 30. In this embodiment, the solid body 30 has a tapered shape in which the diameter gradually increases from the front end to the rear end, as shown in FIG. 5, and the taper ratio is, for example, about 2/1000 to 5/1000. It is. The taper rate of the solid body 30 is constant over the entire length, but need not be constant. The solid body 30 has a length corresponding to the entire length of the blank 10.

<Main layer 31>
The main layer 31 is cylindrical and formed over the entire length of the solid body 30. Therefore, the main layer 31 is formed over the entire length of the blank 10. The entire length of the solid body 30 is covered by the main layer 31, the front end of the main layer 31 is located at the front end 30 a of the solid body 30, and the rear end of the main layer 31 is located at the rear end 30 b of the solid body 30. positioned. The thickness of the main layer 31 gradually increases from the front end to the rear end. The main layer 31 is formed from prepregs 41, 42, 43. The main layer 31 has a longitudinal fiber layer in which the reinforcing fibers are longitudinal fibers over the entire length of the main layer 31, that is, over the entire length of the blank 10. The warp fiber layer is constituted by a plurality of warp fiber prepreg layers formed from a plurality of warp fiber prepregs whose reinforcing fibers are longitudinal fibers.

  The total number of plies of the prepregs 41, 42, 43 at the rear end of the main layer 31 (the total number of turns) is greater than the total number of plies of the prepregs 41, 42, 43 at the front end of the main layer 31. The total number of plies of the prepregs 41, 42, 43 at the front end of the main layer 31 is, for example, 1 ply (one turn), and the total number of plies of the prepregs 41, 42, 43 at the rear end of the main layer 31 is 2 plies or more For example, 2 to 6 plies.

  Specifically, as shown in FIG. 5, the main layer 31 is composed of three sheet-shaped prepregs 41, 42, and 43. In FIG. 5, the prepregs 41, 42, and 43 are simplified and shown in a triangular shape, but each of the front end portions 41a, 42a, and 43a is preferably not sharp but has a predetermined width. The front ends 41a, 42a, 43a of the prepregs 41, 42, 43 each have a width dimension (circumferential dimension) such that one ply can be provided. The plurality of prepregs 41, 42, 43 are individually wound one by one. Accordingly, the main layer 31 has a plurality of prepreg layers formed by separately winding the plurality of prepregs 41, 42, and 43, respectively. The number, size, shape, arrangement, etc. of the prepregs 41, 42, 43 constituting the main layer 31 are arbitrary, but in the present embodiment, the main layer 31 is composed of three prepregs 41, 42, 43. .

  The prepregs 41, 42, 43 constituting the main layer 31 have a shorter length in the direction of the center line of the solid body 30 as the inner one is longer, and a longer length in the direction of the center line of the solid body 30 as the outer side. And extend to the front. The main layer 31 includes a first prepreg layer formed from the innermost first prepreg 41, a second prepreg layer formed outside the first prepreg layer and formed from the second prepreg 42, The third prepreg layer is formed from the third prepreg 43 and is located outside the prepreg layer. The third prepreg layer is the outermost prepreg layer of the main layer 31.

  The rear ends 41b, 42b, 43b of the prepregs 41, 42, 43 are aligned with each other and located at the rear end 30b of the solid body 30. The front end portions 41a, 42a, 43a of the prepregs 41, 42, 43 are located closer to the front as they go outside. The length of the first prepreg 41 is the shortest, the second prepreg 42 is longer than the first prepreg 41, and the third prepreg 43 is longer than the second prepreg 42. The third prepreg 43 has a length corresponding to the entire length of the solid body 30. The front end 42 a of the second prepreg 42 is located on the front side of the front end 41 a of the first prepreg 41. The front end 43a of the third prepreg 43 is located on the front side of the front end 42a of the second prepreg 42 and is located at the front end 30a of the solid body 30. As described above, the rear end of the third prepreg layer, which is the outermost prepreg layer of the main layer 31, is located at the rear end 30b of the solid body 30, and its front end is located at the front end 30a of the solid body 30. I have.

  The reinforcing fibers of the first prepreg 41 and the second prepreg 42 are, for example, carbon fibers and longitudinal fibers. Therefore, the first prepreg 41 and the second prepreg 42 are both longitudinal fiber prepregs, and the first prepreg layer formed from the first prepreg 41 and the second prepreg layer formed from the second prepreg 42 are both formed. It is a warp fiber prepreg layer.

  The third prepreg 43 is a laminated sheet in which the first sheet 51 and the second sheet 52 are laminated. The first sheet 51 and the second sheet 52 have the same shape. The reinforcing fibers of the first sheet 51 are longitudinal fibers, and the first sheet 51 is a longitudinal fiber prepreg. The reinforcing fibers of the first sheet 51 are preferably carbon fibers. The reinforcing fibers of the second sheet 52 are made of a woven fabric, and the second sheet 52 is a woven prepreg. The woven fabric is obtained by vertically and horizontally weaving longitudinal fibers along the center line of the first rod body 1 and transverse fibers along the circumferential direction of the first rod body 1. The reinforcing fibers of the woven fabric are preferably glass fibers. The third prepreg 43, which is a laminated sheet, may be wound so that the first sheet 51 is on the outside, or may be wound so that the second sheet 52 is on the outside, but in the present embodiment, , The first sheet 51 is wound outside. Therefore, the outer peripheral surface of the main layer 31, that is, the outermost surface of the main layer 31 is formed entirely from the first sheet 51 of the third prepreg 43, and the outermost surface of the main layer 31 is formed over the entire length of the vertical fiber prepreg layer. 35. The third prepreg layer formed from the third prepreg 43, which is a laminated sheet, includes a warp fiber prepreg layer 35 (see FIG. 4) formed from the first sheet 51 and a woven prepreg layer 36 formed from the second sheet 52. (See FIG. 6). The reinforcing fibers in the portion of the main layer 31 other than the second sheet 52 are all longitudinal fibers, and are preferably all carbon fibers. Therefore, the portion of the main layer 31 other than the woven prepreg layer 36 formed from the second sheet 52 is a warp fiber prepreg layer formed from the warp fiber prepreg in which the warp fibers are reinforced fibers. In the present embodiment, the vertical fiber layer of the main layer 31 is constituted by the vertical fiber prepreg layer 35 of the first prepreg layer, the second prepreg layer, and the third prepreg layer.

  The number of turns of each of the prepregs 41, 42, 43 is arbitrary, but is preferably one turn (1 ply) or more, more preferably more than one turn, and two turns (2 ply) or three turns ( 3 plies). It is preferable that at least the rear part of the entire length has more than one turn. The number of windings at the front ends 41a, 42a, 43a of the prepregs 41, 42, 43 is one ply or more, respectively, and the number of windings at the rear ends 41b, 42b, 43b of the prepregs 41, 42, 43 is the front end 41a, respectively. The number of turns may be equal to or greater than the number of windings in 42a and 43a, and may be 2 plies or more. Therefore, in the present embodiment composed of three prepregs 41, 42, and 43, the total number of turns at the rear end of the main layer 31 is at least 3 plies, and particularly preferably at least 6 plies. .

<Cross tape layer 32>
The cross tape layer 32 is formed over the entire length of the outer peripheral surface of the main layer 31. The cross tape layer 32 presses the main layer 31 against the solid body 30 and presses the longitudinal fibers on the outer peripheral surface of the main layer 31 inward. The cross tape layer 32 is formed over the entire length of the blank 10. As shown in an enlarged perspective view in FIG. 4, the cross tape layer 32 is formed such that the first and second tape-shaped prepregs 61 and 62 are spirally wound at intervals and cross each other. It is formed by being wound around.

  The first tape-shaped prepreg 61 is spirally wound around the outer peripheral surface of the solid body 30 at intervals without overlapping. The pitch between the first tape-shaped prepregs 61 is arbitrary, and the interval between adjacent first tape-shaped prepregs 61 is arbitrary. For example, the interval between adjacent first tape-shaped prepregs 61 is It is larger than the width of the first tape-shaped prepreg 61.

  The second tape-shaped prepreg 62 is wound around the outside of the first tape-shaped prepreg 61. The lead angles of the first tape-shaped prepreg 61 and the second tape-shaped prepreg 62 with respect to the direction of the center line of the solid body 30 are opposite to each other. The first tape-shaped prepreg 61 and the second tape-shaped prepreg 62 together have an X shape. Each lead angle is, for example, 45 degrees with respect to the center line of the solid body 30. As shown in FIG. 4, the crossing direction of the woven fabric of the reinforcing fibers of the main layer 31 and the crossing direction of the cross tape layer 32 are different from each other, and are in a mutually inclined relationship. The pitch of the second tape-shaped prepreg 62 is substantially the same as the pitch of the first tape-shaped prepreg 61. The reinforcing fibers of the first and second tape-shaped prepregs 61 and 62 are continuous along the longitudinal direction of each of the prepregs 61 and 62 without interruption. The reinforcing fibers are, for example, carbon fibers.

  Note that a synthetic resin is impregnated between the reinforcing fibers. Therefore, the solid body 30, the main layer 31, and the cross tape layer 32 include a synthetic resin in addition to the reinforcing fibers. The type of the impregnated synthetic resin may be various, but the synthetic resin of the solid body 30 and the synthetic resin of the prepregs 41, 42, 43 may be different from each other. The synthetic resin of the prepregs 41, 42, 43 and the synthetic resin of the first and second tape-shaped prepregs 61, 62 can be the same as each other. The synthetic resin of the solid body 30 can be, for example, an unsaturated polyester resin. The synthetic resin of the prepregs 41, 42, 43 and the synthetic resin of the first and second tape-shaped prepregs 61, 62 can be epoxy resin, for example.

<Male side joint part 11>
The male joint portion 11 is formed by a predetermined length region of the rear end of the blank 10. The length of the male joint portion 11 is arbitrary, for example, about several tens mm. An auxiliary prepreg 70 is wound around a predetermined length region of the rear end of the blank 10 to form an auxiliary layer 33. The auxiliary prepreg 70 is wound around the outside of the cross tape layer 32, and the auxiliary layer 33 covers the outside of the cross tape layer 32. The width of the auxiliary prepreg 70 corresponds to the length of the male joint 11. Accordingly, the auxiliary layer 33 is formed only on the male joint portion 11 of the entire length of the blank 10. The male joint portion 11 is formed from a region of the entire length of the blank 10 where the auxiliary prepreg 70 is wound. By polishing the outer peripheral surface of the auxiliary layer 33 to a predetermined outer diameter, the outer peripheral surface of the male joint portion 11 is formed, and the male joint portion 11 can be firmly inserted and fixed to the female joint portion 21. . The cross tape layer 32 may be partially exposed from the surface of the auxiliary layer 33.

<Coating layer 34>
The coating layer 34 is preferably formed on the entire outer peripheral surface of the blank 10, but may be formed only on a part thereof. The coating layer 34 may be formed on the entire area except the male joint 11. By providing the coating layer 34 on the cloth tape layer 32, the surface of the blank 10 can be made smooth. Note that the coating layer 34 may be omitted.

  The fishing rod configured as described above is composed of two rods, a solid first rod 1 on the front side and a hollow second rod 2 on the rear side. Since the first rod body 1 on the front side is solid, it is possible to give a sticky tone. In addition, since the rear second rod body 2 is hollow, it is possible to prevent the fishing rod from becoming too heavy, and to reduce the weight of the fishing rod even though it is a sticky fishing rod.

  In particular, since the first rod body 1 constitutes the main part of the fishing rod, and the first rod body 1 is provided with all the fishing line guides 3 of the fishing rod, the sticky condition up to or near the butt part is obtained. Can be easily put out. A tone close to what is called a one-piece rod can be obtained. Further, since the first rod body 1 includes all the fishing line guides 3, for example, the second rod body 2 can be used by attaching the first rod body 1 of another specification. That is, the first rod 1 and the second rod 2 can be used in combination as appropriate. Moreover, since the second rod body 2 including the reel sheet 4, the first grip portion 22, and the second grip portion 23 is hollow, the weight of the fishing rod can be reduced as compared with a one-piece rod. Since the female joint 21 of the second rod 2 is located inside the cylindrical reel sheet 4, the female joint 21 of the second rod 2 is moved from the male joint 11 of the first rod 1. The vibration is transmitted to the hand via the reel sheet 4. In addition, since the first rod body 1 extends to a position immediately in front of the hand holding the reel sheet 4, it is possible to make a sharp bend to the vicinity of the hand.

  Further, in the main part of the fishing rod, that is, in the first rod body 1 having a length exceeding half of the fishing rod, the main layer 31 is formed on the entire outer length of the solid body 30, so that the bending strength is secured by the main layer 31. The solid body 30 can be made thinner and lighter. In particular, since the reinforcing fibers of the solid body 30 are longitudinal fibers and the reinforcing fibers of the main layer 31 are all longitudinal fibers except for the woven fabric, the bending strength of the blank 1010 of the first rod body 1 is reduced. It can be easily secured. In addition, since both the reinforcing fibers of the solid body 30 and the reinforcing fibers excluding the woven fabric of the main layer 31 are made of carbon fibers, it is possible to obtain a viscous but tight tone.

  Furthermore, the front end 42a of the second prepreg 42 is located on the front side of the front end 41a of the first prepreg 41, and the front end 43a of the third prepreg 43 is located on the front side of the front end 42a of the second prepreg 42. Therefore, when the first rod body 1 is largely bent, the separation of the front end of the first prepreg layer is prevented by the second prepreg layer, and the separation of the front end of the second prepreg layer is prevented by the third prepreg layer. You. By forming the outer prepreg longer toward the front side as described above, the bending strength from the middle portion to the rear end portion of the first rod body 1 can be easily secured without increasing the taper rate of the solid body 30. be able to.

  Since the third prepreg layer, which is the outermost prepreg layer of the main layer 31, covers the entire length of the solid body 30, the solid body 30 is prevented from being exposed. Peeling can also be prevented. Further, since the main layer 31 covers the entire length of the solid body 30, a smooth bending curve can be obtained. In particular, since the vertical fiber prepreg layer 35 of the third prepreg layer covers the entire length of the solid body 30, a smooth bending curve is obtained and the bending strength of the blank 10 can be secured. In addition, since the vertical fiber layer of the main layer 31 is formed over the entire length and the number of windings at the rear end of the vertical fiber layer is larger than the number of windings at the front end and is 2 plies or more, the solid body 30 is formed. It can be made thinner and lighter, and the required bending strength can be secured. Since the vertical fiber layer of the main layer 31 is constituted by the plurality of vertical fiber prepreg layers formed by independently winding the plurality of vertical fiber prepregs, the winding of the vertical fiber layer at the rear end of the main layer 31 is performed. It is easy to increase the number of turns, and the main layer 31 can easily secure the strength and reduce the weight. However, the vertical fiber layer of the main layer 31 may be formed from one vertical fiber prepreg.

  In the first rod body 1, the woven prepreg layer 36 is formed over the entire length of the main layer 31 like a bandage, so that cracks between the longitudinal fibers of the main layer 31 can be suppressed. Since the woven prepreg layer 36 is formed on the third prepreg layer, which is the outermost layer of the main layer 31, the woven prepreg layer 36 generates cracks that are likely to occur near the outer peripheral surface when the first rod 1 is bent. It can be suppressed effectively. In particular, since the reinforcing fibers of the woven fabric are along the direction of the center line of the first rod body 1 and the circumferential direction of the first rod body 1, the generation of cracks between the longitudinal fibers can be effectively suppressed. Since the cross tape layer 32 strongly presses the warp fiber prepreg layer 35 and the woven fabric prepreg layer 36 inward over the entire length, the effect of suppressing the crack generation by the woven fabric prepreg layer 36 is enhanced.

  Further, since the vertical fiber prepreg layer 35 and the woven fabric prepreg layer 36 are formed by winding the third prepreg 43 which is a laminated sheet, the woven fabric of the reinforcing fibers can be easily spread over the entire length of the main layer. Can be wound. Further, by using the laminated sheet, the woven fabric prepreg layer 36 can be made to be adjacent to the warp fiber prepreg layer 35, and the generation of cracks in the warp fiber prepreg layer 35 can be suppressed by the adjacent woven fabric prepreg layer 36. it can. Moreover, when at least the rear part of the laminated sheet is wound beyond one turn and the number of turns is two or more plies, the two or more woven fabric prepreg layers 36 suppress the progress of the inside of the crack.

  Furthermore, since the cross tape layer 32 is formed over the entire length outside the main layer 31, the torsional strength of the first rod body 1 can be secured. Since the auxiliary layer 33 is provided on the male side joint portion 11 outside the cross tape layer 32, the size of the outer peripheral surface of the male side joint portion 11 is easily adjusted by polishing the auxiliary layer 33. be able to. Therefore, even if the cross tape layer 32 is formed up to the rear end of the first rod body 1, the male joint 11 can be firmly inserted and fixed to the female joint 21.

  In the present embodiment, the third prepreg 43 is wound so that the first sheet 51 is on the outside, but the third prepreg 43 is wound such that the second sheet 52 is on the outside as shown in FIG. It may be turned. In this case, the outer peripheral surface of the main layer 31, that is, the outermost surface is entirely formed of the second sheet 52, and the outer peripheral surface of the main layer 31 is formed of the woven prepreg layer 36. When the outer peripheral surface of the main layer 31 is the woven prepreg layer 36, the inside of the vertical fiber prepreg layer 35 is covered with the woven prepreg layer 36, and the exposure of the longitudinal fibers to the outside is prevented.

  In the above embodiment, the taper rate of the solid body 30 is constant over the entire length. However, the taper rate of the solid body 30 may be changed. For example, as shown in FIG. 7, the solid body 30 may include a front portion 80 whose diameter is increased toward the rear side at a predetermined taper ratio, and a rear portion 81 whose diameter is constant. By making the rear part 81 of the solid body 30 a straight shape with a constant diameter, the weight of the solid body 30 can be reduced, and the weight of the first rod body 1 can be further reduced. Then, the taper ratio of the rear portion of the blank 10 can be adjusted by the main layer 31, and the condition of the first rod body 1, particularly, the condition of the rear portion of the first rod body 1 can be easily set.

  In the configuration of FIG. 7, the main layer 31 includes a first prepreg layer formed from the first prepreg 41, a second prepreg layer formed from the second prepreg 42, a third prepreg layer formed from the third prepreg 43, And a fourth prepreg layer formed from the fourth prepreg 44. The first prepreg 41, the second prepreg 42, and the third prepreg 43 are vertical fiber prepregs, and the first prepreg layer, the second prepreg layer, and the third prepreg layer are vertical fiber prepreg layers. The fourth prepreg 44 is a laminated sheet, and the fourth prepreg layer is the outermost prepreg layer of the main layer 31. The fourth prepreg layer has a laminated structure of a warp fiber prepreg layer formed from the first sheet 51 and a woven prepreg layer formed from the second sheet 52. In this embodiment, the vertical fiber layer of the main layer 31 is constituted by the vertical fiber prepreg layers of the first prepreg layer, the second prepreg layer, the third prepreg layer, and the fourth prepreg layer.

  The fourth prepreg layer has a length extending over the entire length of the solid body 30. The front end portion 41a of the first prepreg 41 is located near the boundary portion 82 between the front portion 80 and the rear portion 81 of the solid body 30, and more specifically, is located slightly behind the boundary portion 82. The front end 42 a of the second prepreg 42 is located on the front side of the boundary 82. The front end 43 a of the third prepreg 43 is located on the front side of the front end 42 a of the second prepreg 42. As described above, the front end 41a of the first prepreg 41, which is the innermost prepreg, is located near the boundary 82, and the front end 42a of the second prepreg 42 outside thereof is located closer to the front than the boundary 82. The rear portion 81 of the blank 10 of the first rod 1 can be easily tapered. In addition, since the outer prepreg is longer and the front end is located on the front side, the taper ratio of the rear portion of the blank 10 can be gradually approached to the taper ratio of the front portion, and the fourth prepreg 44 can be neatly wound. Can be turned. Note that the rear part 81 of the solid body 30 may not have a straight shape, and the rear part 81 of the solid body 30 may have a tapered shape that expands rearward at a taper rate smaller than the taper rate of the front part 80. Is also good.

  Although the vertical fiber prepreg layer and the woven fabric prepreg layer in the outermost prepreg layer were formed from the laminated sheet, the vertical fiber prepreg layer and the woven fabric prepreg layer over the entire length of the main layer 31 were separately formed from a single-layer prepreg. It may be formed. In that case, the longitudinal fiber prepreg layer and the woven prepreg layer over the entire length of the main layer 31 are preferably adjacent to each other.

  Further, in the above embodiment, the male side joint portion 11 of the first rod body 1 is constituted by the predetermined length region of the rear end portion of the blank 10, but as shown in FIG. The joint part 11 may be constituted by a ferrule 90 attached to the rear end of the blank 10. FIG. 8 shows an example of a configuration in which the male joint 11 is a ferrule 90. A ferrule 90 is attached to a predetermined length region of the rear end of the blank 10 of the first rod body 1. The ferrule 90 has a tubular shape with a front end opened and a rear end closed, and is mounted and fixed outside the blank 10. The rear end of the ferrule 90 is the rear end of the first rod 1. A coupling nut 91 is provided outside the front part of the ferrule 90. A grip portion 92 is mounted on the front side of the connecting nut 91. When connecting the first rod 1 to the second rod 2, the ferrule 90 is inserted into the female joint 21 of the second rod 2, and a not-shown member provided inside the female joint 21 is provided. The engaging groove 90a of the ferrule 90 is engaged with the mating pin. Then, the first rod 1 is brought close to and fixed to the second rod 2 by screwing the connecting nut 91 into the male screw portion 93 at the front end of the second rod 2. Note that the male screw portion 93 at the front end of the second rod body 2 may be formed on the reel sheet 4, for example.

  In the above embodiment, the first rod body 1 is provided with all the fishing line guides 3 of the fishing rod, and the second rod body 2 is not provided with the fishing line guides 3. One or more fishing line guides 3 may be provided. Further, the first rod 1 and the second rod 2 may have substantially the same length. The number of joints may be three or more.

  Further, although the main layer 31 is formed over the entire length of the solid body 30, the main layer 31 may not be formed on the front end 30a and the rear end 30b of the solid 30. The main layer 31 may be formed in the remaining length excluding the male joint portion 11 without forming the main layer 31 in the male joint portion 11 in the entire length of the solid body 30. The cross tape layer 32 may not be provided on the entire outer peripheral surface of the main layer 31. For example, the cross-tape layer 32 may not be formed on the male-side joint portion 11, or the cross-tape layer 32 may be formed on the entire length of the main layer 31 excluding the male-side joint portion 11.
