Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod capable of varying the tone of a rod tip or the like.

[0002]

2. Description of the Related Art When using a fishing rod, there are times when it is desired to change the tone of the rod in use. As a method for this, in the case of a continuous fishing rod, a plurality of spare tips having different tones may be prepared and the tips having a desired tone may be used. Further, as disclosed in Japanese Utility Model Laid-Open No. 4-41256, the condition of the fishing rod can be changed by holding the tip rod in the shortened state housed in the ear holding rod.

[0003]

However, in the former case, it is necessary to prepare a plurality of spare tips and carry them around, which is inconvenient to handle. In the latter, the tone of the fishing rod can be changed, but since the tip rod is stored in the head holding rod, the bending rigidity of the head holding rod and the bending rigidity of the tip rod are polymerized over the storage area.
Compared to the bending rigidity of the spikelets in the region immediately after the overlapping region,
The fishing rod has a sharply increased flexural rigidity in the front overlapping region. Therefore, the bending balance is poor and the condition is such that the fishing rod cannot be used. In addition, stress concentration may occur in the spike-holding rod immediately after the overlapping region, which is the region where the rigidity sharply decreases, and the fishing rod may be damaged.

Therefore, an object of the present invention is to provide a fishing rod which can change the condition of the fishing rod, has a good flexural balance, and has a good rod condition. In addition, the aim is to provide a fishing rod with less stress concentration.

[0005]

SUMMARY OF THE INVENTION In view of the above object, the present invention provides, in claim 1, the front rod rod so that the front rod rod can be pulled out in the forward direction of the rear rod tube and can be stored in the original direction, and in the pulled out state. It is a fishing rod with a variable tone constructed so that it can be respectively held in the stored state, in a state corresponding to the rear end of the front rod rod in a state where the front rod rod is stored and held in the rear rod pipe. It is characterized in that the bending rigidity of the rear rod tube in a region extending a predetermined distance from the vicinity or from the front side to the rear side is rapidly increased with respect to the bending rigidity of the rear rod tube in the front region. To provide a fishing rod. This front rod may be a tubular body or a solid body, and so on.

According to a second aspect of the present invention, the front rod rod and the rear rod pipe are formed of fiber reinforced plastic, and the front rod rod is made of axial reinforcing fibers having a larger longitudinal elastic modulus than the rear rod pipe. Configure to use more.

According to the first aspect of the present invention, when the front rod rod is stored and held in the rear rod tube, the bending rigidity of the front rod rod and the rear rod tube is overlapped in the accommodated region, so that the bending rigidity becomes high. However, immediately after that, there is only the rear rod tube, and in general, the rigidity suddenly drops sharply. In order to prevent this, the bending rigidity of the rear rod pipe in the vicinity of the position corresponding to the rear end position of the front rod rod, or in the region extending a predetermined distance rearward from the position on the front side of the position, Since the front rod region is steeply raised as compared with the rear rod pipe region, the difference in rigidity between the overlapping region and the rear rod pipe region immediately thereafter is reduced. Therefore, the difference in rigidity due to the polymerization is reduced, the bending balance is improved, and the rod tone is improved.

That is, in the structure in which the bending rigidity is greatly reduced in a stepwise manner over the long range of the rear side rod tube behind it when stored and polymerized, the superposition area having high rigidity on the front side is bent during fishing. However, the bending concentrates on the rear portion having low bending rigidity, and the bending balance and the rod tone deteriorate, but the structure of the present invention improves this.

Further, when the front rod rod is pulled out and held, in the predetermined length range of the rear rod tube, the rigidity is sharply increased as compared with the front region thereof, but the rigidity at the rear position is to the last. Therefore, the bending balance of the fishing rod does not change from the front position, and the bending balance in the middle region of the rear rod tube changes smoothly without a sudden increase. And the deterioration of the tone is prevented. Therefore, even when the front rod is pulled out and used, it can be used without any discomfort.

In the second aspect, since the front rod rod uses more axial longitudinal reinforcing fibers having a larger longitudinal elastic modulus than the rear rod tube, the outer diameter dimension having the required bending rigidity can be reduced,
It is easy to form a small outer diameter so that it can be stored in and pulled out from the rear rod tube.

A holding portion 10H is provided at the front end of 0, and a rotating mechanism 28 having a flexible member 24 such as a lilyan attached to a fixed portion 10K integrated with the holding portion 10H is provided.

At the tip of the second tip rod 12, a cylindrical body 30 which cooperates with the holding portion 10H and holds the region L1 of the first tip rod 10 is also provided. Pole 14
A cylindrical body 32 having a similar function is fixedly attached to the tip of the.
At a predetermined position of the second tip rod 12, a holding portion 12H that cooperates with the cylindrical body 32 and holds the region L2 of the second tip rod 12 in the drawing is provided. Reference numerals 34 and 36 are mouthpieces, and 22 is a rod end part.

The first tip rod 10 and the second tip rod 12 correspond to the front rod rod and the rear rod tube, respectively, described in the claims.
The second tip rod 12 and the first middle rod 14 correspond to the front rod rod and the rear rod tube, respectively, described in the claims. In the following description, the former first tip rod 10 and the second one shown in FIG.
The description will be centered on the tip rod 12, but the same applies to the latter case. Further, other adjacent rod tubes may be used. Furthermore, the fishing rod does not have to be the swing-out type as in this example, and may be a splicing joint, a reverse splicing joint, a spigot joint, or the like, or a combination thereof. There may be no middle rod, the number is arbitrary, and the length of each rod tube is also arbitrary.

A region L1 of the first tip rod 10 which is substantially straight or has a taper taper in a taper shape within a length range of 1/2 or less of the length of the second tip rod 12 excluding the former side joint. Are stored, but it is preferable to store them in a length range of 1/3 or less. However, as will be described with reference to FIG. 3, the storage length can be set to a desired length by improving the balance of bending rigidity. The second tip rod 12 is the first tip rod 1
12A of the front pipe part which is a storage area of 0 and is almost straight
And a rear pipe portion 12C that is a region close to a straight line, and a middle pipe portion 12B that is an enlarged diameter region.

A holding portion 10H is provided at the tip of the first tip rod 10.
A fixed portion 10K integrated with the above is adhered and fixed, and a shaft portion J is projectingly provided at the tip of the fixed portion 10K. Is rotatably disposed in the rotary mechanism 28. 2
6 is a binding portion of the fishing line 40. Holding part 10H and fixing part 1
It may be separate from 0K.

The tip side reduced diameter portion 30S of the tubular body 30 provided at the tip end portion of the second tip rod 12 is reduced in diameter, and an internal thread is formed on the inner periphery thereof and a step portion ST is formed. Has been done. On the other hand, a male screw that can be screwed into this female screw is provided on the outer periphery of the holding portion 10H, and the first tip rod 1
When 0 is stored in the second tip rod 12, the first tip rod 10 is held and locked by being screwed together. In this case, when screwing in such a thin portion of the rod tip, the shaft centers are difficult to align and have angles with each other, and if they are forcibly screwed together, they will be damaged. In order to prevent this, the holding portion 10
The guide portion 10E is extended to the rear of H and is guided by a small inner diameter portion behind the female screw of the reduced diameter portion 30S during screwing. This facilitates screwing.

Further, the step portion ST acts as a stopper, and the screwing of the first tip rod 10 is stopped at a predetermined position, whereby positioning can be performed with a feeling of moderation and holding engagement can be confirmed. Other than screwing, a locking structure that engages and disengages at the time of storage by a concave portion and a convex portion in the radial direction or other press-fitting locking structure may be used, but the screwing locking structure stabilizes the holding. In addition, the rear end edge 30T of the tubular body 30 is formed in a tapered shape as shown in the figure, and the tip portion of the tubular body is reduced in diameter as described above, and such a structure prevents catching of fishing line. . The rear end edge 10ET of the guide portion 10E is also formed in a taper shape, so that the fishing line can be prevented from being caught when the first tip rod 10 is pulled out and used.

Further, in the case of a fishing rod having a through hole or a rod having a fishing line guide on the outer side, the flexible member 24 having a rotating mechanism at the tip end portion thereof.
Is a top guide, and a screw or the like is provided at the base of the top guide to lock the reduced diameter portion 30S by screwing or the like. In the case of the locking structure by screwing, the outer shape of the fixing portion 10K may be circular, but it may be polygonal or elliptical, flat portion or a large number of smooth and low protrusions (which are unlikely to catch fishing line) or the axial direction. By forming the ridge (which is unlikely to be caught by fishing line) extending in the direction, the holding portion 10H can be easily rotated by holding the fixing portion with fingers, and the engaging / disengaging operation is facilitated.

On the other hand, at the rear end portion of the first tip rod 10, FIG.
As shown in the enlarged view in FIG. 3, when the first tip rod 10 is pulled out and held, a tapered joint portion 10T that engages with the inner surface of the tip of the second tip rod 12 is formed. The press contact portion 10A is formed. The pressure contact portion 10A is provided with a notch 38 which is open at the rear, and when it is freely opened, the diameter thereof becomes larger than the inner surface of the tip tube portion 12A of the second tip rod 12.

Therefore, the pressure contact portion 10A constantly presses the inner surface of the second tip rod 12 while it is being inserted through the inside of the tip tube portion 12A having the inner surface of the straight or loose front taper shape, and is appropriately slid. It gives resistance. Therefore, when the first tip rod 10 is housed as shown in FIG. 2, the front portion is held and fixed by screwing the holding portion 10H and the reduced diameter portion 30S and the rear end portion as described above. Is also held, and a steady rest is made during fishing. The middle tube portion 12B is the front tube portion 12
The diameter is increased sharply with respect to A, and the wall thickness is increased.

FIG. 3 shows the first tip rod 10 at the tip of the fishing rod of FIG.
It is the figure which showed roughly the change of the bending rigidity R of the 2nd tip tip rod 12. The area Z1 is a splicing portion and a pressure contact portion when the first tip rod 10 is pulled out and used, and the area Z2 is a rear end portion of the first tip rod when the first tip rod 10 is housed and used. And corresponds to the region between the joint portion 10T and the pressure contact portion 10A. The bending rigidity of the first tip rod 10 is line C1, the bending rigidity of the tip tube portion 12A of the second tip rod 12 is line C2, the middle tube portion 12B is line C3, and the rear tube portion 12C.
Is line C4. Line C2 "is the second tip 12
It is an imaginary line of bending rigidity when the middle pipe part and the rear pipe part are manufactured in an extended state of the front pipe part 12A. In addition, the line C2 ′ indicated by the broken line is the second tip of the first tip rod 10.
It is the polymerized bending rigidity when stored in the tip rod 12.

In the present invention, the rigidity of the rear region (up to the rear tube portion 12C) is set to increase sharply with respect to the front region of the region Z2 of the second tip rod 12 as a boundary. There is. When the first tip rod 10 is pulled out and spliced, the bending rigidity of the fishing rod is gradually increased rearward except for the splicing region Z1 which is a narrow range, so that the bending balance is good and the rod is in good condition during fishing. Further, when stored and held, the rigidity is lowered at the place where the bending rigidity line C2 ′ shifts to C3. That is, the line C2 ′ is changed to C3 at the trailing edge of the region Z2. In this example, the flexural rigidity of the lowered change point P2 is about 85 when the rigidity of the reference point P1 of the line C2 ′ excluding the narrow area Z2 is 100. On the other hand, if the second tip rod 12 has the rigidity indicated by the line C2 ″, the bending rigidity at the point P2 ′ is about 62.

According to the experiment, if the change point P2 is within ± 25% of the change in bending rigidity with respect to the reference point P1, the bending vance is good and the rod tone is good. Furthermore, stress concentration can be prevented and it is difficult to damage. It is more preferable if it is within about ± 15%. Therefore, in the case of the line C2 ", the deflection balance is poor and the rod condition is not good, but in the case of the line C3 of the present invention, it is improved and the deflection balance is good and the rod condition is good. Also, damage due to stress concentration is prevented. Regarding the stress concentration alone, damage is prevented if the bending rigidity changes within about ± 30%, and if it changes about ± 30%, the flexure balance becomes a little bad and the rod is a little bad. In addition, the balance (tone) is improved compared to the conventional one, and the rigidity of the rear part is considerably increased compared to the rigidity of the tip part of the tip tube part of the second spike tip, as in the case of the fishing rod of the tip condition. By increasing the rigidity of the tip of the subsequent middle tube and making the rigidity of the base of the first tip rod relatively low, the rigidity of the overlapping portion at the time of storage and the second tip of the second tip rod Rigidity does not change significantly, which improves the bending balance. Can be.

As described above, the first tip rod 10 stored.
The second from within the region Z2 that is near the position corresponding to the rear end of
It is preferable to sharply increase the bending rigidity of the tip rod, but this is not necessarily limited to this, and from the position further forward than that, or in the vicinity of the position corresponding to the rear end of the first tip rod 10 at the rear end position. Even if it is suddenly raised from a position further back than that, the bending balance is hardly deteriorated, and the rod condition is hardly deteriorated. That is, in this case, the difference in rigidity is reduced to, for example, about 62% at the trailing edge of the area Z2. However, this reduction (change) range is a narrow range (nearby), so the flexural balance is greatly affected. Is not given.

FIG. 4 is a view for explaining the manufacture of the second tip rod 12 of the present embodiment, in which the cored bar 50 has a taper portion 50A of a joint portion formed at the tip end thereof, and a substantially straight portion 50B.
Followed by a large tapered portion 50C and a substantially straight portion 50D. A main body prepreg 52 having similar reinforcing fibers 52B oriented substantially in the longitudinal direction on a layer of reinforcing fibers 52A such as carbon fibers oriented substantially in the circumferential direction.
And the reinforcing fiber 54B is oriented substantially in the longitudinal direction, and the trapezoidal main body prepreg 54 whose front end is located at the rear portion of the straight portion 50B is wound, and the auxiliary prepreg 56 in the form of a woven cloth is wound.
The joining portion at the rear end is reinforced by the method. Therefore, in this embodiment, the shape is formed in a large taper shape, and
A rapid increase in rigidity is achieved by increasing the axial length fibers in this region to increase the wall thickness. In addition, there is a method of using the reinforcing fiber 54B of the main body prepreg 54 as a material having a higher longitudinal elastic modulus than the reinforcing fiber 52B.

Since the first tip rod 10 is housed in the second tip rod 12, its outer diameter is considerably smaller than that of the second tip rod. Therefore, if they are made of the same material, when they are pulled out and used, a large difference occurs in the bending rigidity of both the tip rods, and the deflection balance is generally deteriorated except for rods with extreme tones. Therefore, many axial reinforcing fibers used for the first tip rod 10 have a higher longitudinal elastic modulus than the second tip rod 12, and the first tip rod 10 has high rigidity for a small diameter. Can be manufactured.

FIG. 5 shows a structure in which the first tip rod 10 and the flexible member 24 and their mounting and fixing portions shown in FIGS. 1 and 2 are configured to be detachable so that the space between the first tip rod 10 and the second tip rod 12 is increased. Even if dirt is accumulated on the first tip rod 10, the first tip rod 10 can be pulled out from the rear portion of the second tip rod 12, and maintenance such as cleaning can be easily performed. That is, FIG.
An internal thread is formed on the inner periphery of a holding portion 10H ′ that is integrated with a fixed portion 10K that holds a flexible member 24 rotatably by providing a shaft portion similar to the above, and the corresponding portion of the first tip rod 10 A male screw 10N is formed and screwed. Therefore, when necessary, the screwing may be removed to disassemble, and only the first tip rod 10 may be pulled out rearward from the second tip rod 12. Further, the first tip rod 10 is pulled out, and the fixing portion 10K with the flexible member 24 is directly attached to the second tip rod 12 via the holding portion 10H ', and is also used as a hard fishing rod with a tip without the first tip rod. it can. In order to prevent accumulation of the above-mentioned stains, prevention of a strange odor due to the stains, and prevention of attachment of fishing line, it is preferable that the outer peripheral surface of the first tip rod and the inner storage surface of the second tip rod be subjected to water repellent treatment with a fluororesin or the like. . If water droplets are prevented from adhering, dirt will not easily accumulate.

As in the case of FIG. 2, the guide portion 1 for guiding when the first tip rod 10 is screwed into the second tip rod 12 for storage.
0E is provided behind the holding portion 10H '. Since the male screw 10N and the like are finer screws and have a small-sized fixing structure, it is not easy to screw them with only the screw portion. Therefore, here, the guide shaft 10 protruding to the front side of the male screw 10N is used.
E'is provided, and the fixed portion 10K has this guide shaft 10E '.
Plays the role of a guide tube. The guide axis is
It may be provided at the rear of the male screw, and in this case, the holding portion 10
A guide cylinder is provided behind H '.

In addition to the above screw-threaded structure, other detachable structure such as press-fitting or concave-convex fitting may be used. Further, instead of the rotating mechanism 28 that allows the flexible member to rotate, a fishing rod provided with a fishing line guide on the outside of the rod or a top guide for a hollow fishing rod may be used. The other structure is similar to that of FIG.

Although the structure of FIG. 6 has been described above, since the pressure contact portion 10A independent of the joint portion 10T is provided, even if the joint portion 10T is pulled out forward, the presence of the independent joint portion 10T ensures the joint. The first tip rod 10 is the second
When the tip rod 12 is pulled out, the presence of the pressure contact portion 10A can impart stable sliding resistance. A front-side fishing rod having a variable tone, wherein the front rod rod of the rod tip can be pulled out in the forward direction of the rear rod tube and stored in the original direction, and can be held in the pulled-out state and the stored state, respectively. Sliding resistance when pulling out the rod from the rear rod tube is 20 ~ 500g
It is a heavy fishing rod.

Since the sliding resistance when the front rod is pulled out from the rear rod pipe is 20 to 500 g weight, the fishing rod is carried out with the front rod rod housed and held in the rear rod pipe. There is resistance when pulling out even if the fish is caught while it is being held and the holding state is accidentally disengaged, it moves slickly, and it suddenly pulls out and suddenly stops (because it is a structure that is spliced even in the pulled out state) You can prevent it, you can reduce the shock at that time,
It is possible to prevent thread breakage and damage to the rod. The upper limit is set to 500 g because if the sliding resistance is higher than this, it will interfere with the normal pulling and storing operations, especially with the exception of a rod with a hard rod tip (extremely pointed rod). ,Preferably,
The weight is about 20 to 250 g. Especially for a fishing rod with a hard rod tip, the weight is about 50 to 500 g.

If the inner surface of the tip tube portion 12A of the second tip rod 12 is a gentle taper taper, when the first tip rod 10 is pulled out, the sliding resistance gradually increases as the withdrawal length becomes longer. It becomes larger and the shock can be effectively mitigated.
FIG. 7 shows another form of the press contact portion. That is, the pressure setting portion 10
An elastic body 42 such as a spring that constantly urges A ′ to radially expand is disposed in the hollow portion 38 ′.

In any of the above cases, the pressure contact portion is formed integrally with the tip rod, which has high strength and can be made smaller and lighter. However, it may be formed separately and connected. In order to stabilize the sliding resistance, it is preferable to expand the diameter to a larger diameter than the inner diameter of the rod tube that receives pressure from the pressure contact portion and to elastically reduce the diameter. Furthermore, a protrusion like a part of a sphere is formed on the outer circumference of the press contact portion, a sphere is embedded, or a sphere is embedded rotatably to stabilize the sliding resistance in the axial direction and to prevent sliding during sliding. It is good to prevent hanging.
In addition, the surface of the pressure contact portion, or the surface of the rod tube that contacts the pressure contact portion is coated with fluorine, a lubricant is coated, or a metal film such as nickel or chromium is formed,
It is advisable to form a uniform minute rough surface to form an adjusting function for stabilizing the sliding resistance and adjusting the size. The joining portion is also the same as the above-mentioned press contact portion, and sticking can be prevented by providing a hardness difference between the contact surfaces, making different materials, or making the surface rough.

The first tip rod 10 is housed and held in the second tip rod 12, but is held in the retaining state by the engagement of the front portion by screwing the reduced diameter portion 30S and the holding portion 10H. At the same time, the rear part is only held by the press contact part, and is slidable and rotatable, and the fixing force of the rear part is formed to be small and movable, so that even if the second tip rod bends. The housed first tip rod 10 can be freely bent, so that it is possible to prevent the bending and adverse effects on the tone, and also to prevent the pressure contact portion from being damaged.

As shown in FIG. 8, the pressure contact portion may be formed inside the second tip rod. That is, the tip end of the second tip rod 12 is formed with a reduced diameter portion 30S on the tip side of the tubular body 30, and an annular elastic body is arranged inside the large diameter portion of the tubular body 30 to provide the first tip rod. The pressure contact portion 10A ″ is provided on the surface of 10 '. It can be easily formed by using a foam material such as a rubber material or sponge, or a spring body. The holding portion 1 is provided on the rear side of the fixing portion 10K.
OH 'is integrally formed, and in this example, the reduced diameter portion 30S
It is configured so that it can be press-fitted and held on the inner surface of the. The step portion ST is a stopper.

FIG. 9 shows another embodiment of the present invention. The fishing rod has a fishing line guide on the outside of the fishing rod, and the fishing line guides must be aligned with each other. In the screwing method described with reference to FIG. 2 and the like, at the end of screwing, for example, the top guide 66.
Is not aligned with another fishing line guide 68, or whether the directionality with the reel mounted in the reel mounting portion (not shown) matches. In addition, even if the bending and hardness (tone) are different depending on the circumferential position of the rod, even if the first tip rod 10 is housed and screwed, the direction is set to a specific desired direction. It is what is done.

The first tip rod 10 is fixed to the base portion 66K of the top guide 66, and a pipe member 60 having an external thread is attached to the outer periphery of the first guide rod 66 so that it can be rotated only with respect to the base portion 66K. There is. On the other hand, a cylindrical body 30 is fixed to the tip portion of the second tip rod 12, and a female screw that can be screwed into the male screw of the pipe member 60 is provided on the inner surface of the reduced diameter portion 30S at the front portion thereof. Therefore, the pipe member 60 can be screwed and rotated by aligning the direction of the top guide 66 with the other fishing line guide 68.

In this case, as described in the case of FIG. 2 and the like, since the screwing work in the rod tip region is unstable, the guide portion 62 integrated with the first tip rod 10 and the inner surface of the tubular body 30 are integrated. It is possible to make the axes of the first tip rod and the second tip rod substantially coincide with each other by the cooperative action with 30N to facilitate screwing. Therefore, the guide portion 62 and the inner surface 30N of the tubular body 30 may have a circular cross section, but may have a polygonal shape or a shape having a flat surface portion to define the direction of the top guide 66.
The fishing line guide 68 is attached to the tubular body 30, which may be a fixed type or a movable type. Further, 10A is a press contact portion.

FIG. 10 shows a modification of FIG. 9 in which the pipe member 6
The tubular nut member 64, which is replaced by 0, is rotatably engaged with the front side reduced diameter portion of the tubular body 30. On the other hand, a male screw is formed on the outer periphery of the base portion 66K of the top guide 66, and a female screw that can be screwed into the male screw is formed on the inner surface of the tubular nut member 64. Therefore, the top guide 66
Can be screwed while keeping the direction of the other fishing line guide 68 aligned. Base 6 of top guide 66
The guide portion 66A extended to the rear part of 6K is the guide portion 6 of FIG.
Similar to 2, the first tip rod 10 cooperates with the inner surface 30N of the tubular body.
To assist the screwing work. The polygonal shape may be used as in the above case.

FIG. 11 shows the first tip rod 10 and the second tip rod 12
In the case of a rod having a top guide 66, it can be screwed while determining its direction similarly to the case of FIG. 9 or FIG.
It may be used in the case of rods such as the above, or for holding and fixing the floating fishing line guide. The cylindrical body 30 fixed to the tip of the second tip rod 12 has its tip reduced in diameter to provide a male screw on the outside,
And the vertical division is put. Further, since this male screw portion is formed in a tapered taper, the first tip rod 10 and the second tip rod 12 can be tightly held by screwing the nut member 72.

The fishing line guide 70 is a floating fishing line guide for the first tip rod, and when the first tip rod is stored as shown in FIG. 11, the base 66K of the top guide 66 is held as a seat. When it is pulled out and used, it is held on the catch 10U at an intermediate position.

FIG. 12 and FIG. 13 show an example of the embodiment to which the present invention is applied in the case of a fishing line fishing through. In FIG. 12, a top guide 76 having a large-diameter guide ring G1 and a small-diameter guide ring G2 is fitted and fixed to the tip of the first tip rod 10 and a male screw is formed on the outer periphery of the base 76K. . On the other hand, a cylindrical body 30 is attached to the tip end portion of the second tip rod 12, and a female screw is provided on the inner surface of the reduced diameter portion 30S at the front portion of the cylindrical body 30 and the both are screwed and held. Top guide 76
A guide portion 76A is formed by extending the rear portion of the male screw of the base portion 76K, and guides the screwing work in cooperation with the inner circumference of the tip portion of the joint portion 12T of the tip portion of the second tip rod 12.

Numeral 10T is a joint portion, and when the first tip rod 10 is pulled out, the joint portion 12 of the tip portion of the second tip rod 10 is pulled out.
Spliced to T. Further, 10A is a pressure contact portion,
The inner surface 10S near the pressure contact portion is an inclined surface whose diameter is expanded rearward, and the fishing line to be inserted is smoothly introduced into the guide ring G3 at the front portion thereof.

In FIG. 13, the second tip rod 12 has a front large-diameter tube portion 12D, which is an area for accommodating the first tip rod 10, on the front end portion of the rear-side small-diameter tube portion 12S. As a result, the diameter of the first tip rod 10 can be set to be large, and the inside through which the fishing line is inserted can be made as large as possible. In this case, as compared with the small-diameter tube portion 12S, the large-diameter tube portion 12D may be formed to have a thinner wall, a low-elasticity fiber may be used for the axial length direction fiber, or the axial length direction fiber may be reduced. It goes without saying that the bending rigidity described in 3 is adjusted. The same applies to the bending rigidity in the case of FIGS. 9 to 12. Cylinder 30
The diameter of the first tip rod 10 can be increased due to the fact that the front portion of the first tip rod is not reduced, and the guide ring G3 is fixed to the guide ring holder HG, and is attached to and detached from the rear end of the first tip rod. Other configurations and operations are the same as those in the case of FIG. 12 except that they are freely screwed and the maintenance such as cleaning inside the first tip rod is easy.

[0045]

As is apparent from the above description, according to claim 1 of the present invention, it is possible to change the condition of one fishing rod and to provide a fishing rod having a good deflection balance and a good fishing condition. . According to claim 2, in addition to the above effect, the front rod rod uses a large amount of axial reinforcing fibers having a larger longitudinal elastic modulus than the rear rod tube, so that the outer diameter dimension having the required bending rigidity is small. Therefore, the front rod rod can be easily formed to have a small outer diameter so that it can be housed in and pulled out from the rear rod tube.
