Description

  The present invention switches between a state in which the small-diameter side housing is accommodated in the large-diameter side housing and a state in which the small-diameter side housing is pulled out from the large-diameter side housing from the stowed state, and the extended state is maintained. It relates to a swinging rod provided with a section.

As the above-described mating portion, an inclined surface that is in pressure contact with the outer peripheral surface of the butt end side end portion of the small-diameter side casing and the inner peripheral surface of the tip end side end portion of the large-diameter side casing is provided. It is formed. The extended state of the small-diameter side housing is maintained by the pressure contact state between the inclined surfaces.
In the case of adopting a configuration in which the extended state of the small-diameter side casing is maintained in the pressure contact state as described above, when moisture or the like is interposed on the pressure contact surface, a so-called fixed state appears. In other words, even if you try to return the small-diameter side housing from the extended state to the contracted state, both inclined surfaces are strongly bonded at the pressure contact part, so even if normal return force is applied, the extended state can be released It happens that you can't.
Therefore, in this case, it is impossible to pay, and it is difficult to finish.
In consideration of these points, a small protrusion is formed on the outer peripheral surface of the rear end of the small-diameter rod as the small-diameter side rod and presses against the inner peripheral surface of the tip of the large-diameter rod as the large-diameter side rod. There is a configuration in which a discharge path is formed so that moisture does not intervene between the inner and outer peripheral surfaces (see Patent Document 1).

Noto 2569413 (paragraph numbers [0009] [0012], FIG. 1)

Certainly, it can be said that the sticking phenomenon is promoted when moisture is present in the mating portion, but the sticking phenomenon is not limited to that. That is, as shown in the above prior art, the mating portion is in a pressure contact state between the inclined inner peripheral surface on the tip side of the large-diameter side casing and the inclined outer peripheral surface formed on the buttock side of the small-diameter side casing. Is what happens. When both inclined surfaces are in pressure contact state, the heel end opening of the large-diameter side housing receives a force in a widening direction, and the buttock side end of the small-diameter side skeleton receives a contracting force and elastically deforms from each other. It will be pressed in the state. Therefore, since it press-contacts in an elastic deformation state, it will be in a stronger joining state and will be in the state where it is difficult to return to the original state.
Such a pressure contact state is considered to be no exception to the conventional technology achieved by pressing the small protrusion against the inclined surface on the other side. Even if the structure is more resistant to sticking compared to the case where no small protrusions are formed by being strongly pressed against the inclined surface, the point of instantaneous contact with pressure cannot be eliminated when performing the alignment operation. It was necessary to improve the mating part.

  An object of the present invention is to provide a fishing rod housing that can eliminate such a drawback and avoid a fixed state while reducing a manufacturing burden.

〔Constitution〕
Claims characterizing feature of the invention according to claim 1, the small-diameter-side rod body to form a mating portion for holding under tension to the large-diameter rod body, the registration unit, the said small-diameter rod body diameter a straight cylindrical portion formed on one of the rod body of the side rod contact surface has a constant diameter, the said smaller diameter rod body is formed on the other of the rod body and the large diameter side rod body said straight cylindrical portion And a reinforcing fiber group in which the surface layer in contact with the projecting surface portion in the straight cylindrical portion is arranged along a predetermined inclination angle with respect to the vertical axis. The prepreg having the prepreg and the prepreg having the reinforcing fiber group arranged so as to be symmetric with respect to the saddle axis and the reinforcing fiber group of the prepreg, and the straight cylindrical portion of the projecting surface portion. The contacting surface layer There in that the reinforcing fiber group was drawn aligned arranged along the axial direction of the body are constituted by a prepreg impregnated with a resin, the effects thereof are as follows.

[Action]
By forming a straight cylindrical part on one side of the mating part, even if a sudden stretching operation is performed, a state in which the projecting part comes into contact with the straight cylindrical part appears, so that the operating force is generated between the projecting part and the straight cylindrical part. At the same time, since the constant resistance force continues due to the presence of the straight cylindrical portion, the state is also recognized by the angler and suddenly falls into a fixed state.
In addition, since a projecting surface portion made of a prepreg is employed as the other side in contact with the straight cylindrical portion, the resistance against wear or the like is stronger than that in which small projections are formed of resin or the like.
However, the projecting surface portion is not simply formed by a prepreg containing reinforcing fibers, and the reinforcing fibers are aligned in the direction along the vertical axis so that the reinforcing fibers are pulled in the circumferential direction. It is easier to bend and deform compared to the case where they are aligned. For example, when the cross section of the ridge is about to be deformed into an ellipse, if the reinforcing fibers are arranged in the circumferential direction, the cross section is deformed because the reinforcing fibers try to prevent the deformation by exerting a counter force. It becomes difficult to do. On the other hand, when the reinforcing fiber arranged in the axial direction is deformed into an ellipse, the deformation preventing force is not large compared to the case where the reinforcing fiber is arranged in the circumferential direction. This means that the projecting surface portion tends to bend in the radial direction. When the projecting surface portion moves in contact with the straight cylindrical portion, the projecting surface portion slightly bends. Thus, it is possible to avoid a strong contact between the projecting surface portion and the straight cylindrical portion. Accordingly, when the small-diameter side casing is pulled out from the large-diameter side casing, the drawing resistance becomes stable.
In addition, the surface layer of the straight cylindrical portion is symmetric with respect to the prepreg having reinforcing fiber groups arranged along a predetermined inclination angle with respect to the saddle axis, and the reinforcing fiber group of the prepreg and the saddle axis. Reinforced fibers arranged in an inclined state even when a shearing force that is inclined in the axial direction is applied, because the prepreg having reinforcing fiber groups arranged in an aligned state is overlapped. Exerts a counteracting force and can prevent resin peeling and plastic deformation of the mating portion.
And since the surface layer of the straight cylindrical portion is arranged in a state in which the direction of the reinforcing fiber is inclined with respect to the saddle axis, the cross section is as described above compared to the case where the reinforcing fiber is arranged in the circumferential direction. Combined with the fact that the projecting surface portion is arranged so that the reinforcing fibers are aligned along the axial direction as described above, and the projecting surface portion is easily deformed. Even when the surface part is formed in a state where it deviates from a predetermined dimension, the other party has good dimensional absorbency following it, and the contact state between the straight cylindrical part and the projecting surface part is deformed in at least one of them. However, it is possible to provide a stable contact resistance and a constant drawing resistance.
And since it becomes the structure which deform | transforms easily in both, an excessive stress does not act and it can suppress peeling and plastic deformation of resin.

〔effect〕
Therefore, the point that forms the straight cylindrical part, the point that makes the counterpart contacting the straight cylindrical part the shape of the projecting surface part, the point that the projecting surface part is formed by the prepreg, and the reinforcing fiber of the prepreg are aligned along the axial direction The point that the straight cylindrical part is formed with the prepreg and the modification that draws the reinforcing fiber of the prepreg in a state inclined in the axial direction can suppress the peeling and plastic deformation of the resin, and the sticking phenomenon It was possible to prevent this, and it was possible to improve the operational feeling when the small diameter side casing was pulled out from the large diameter side casing and the matching operation was performed.

Characterizing feature of the invention according to claim 2, to form a conical inclined supporting surfaces in a state adjacent to the rod destination end side of the straight cylindrical portion with an inner peripheral surface of the large-diameter rod body, the small A cone-shaped inclined contact surface that contacts the inclined receiving surface is formed on the outer peripheral surface of the side casing, and the effects thereof are as follows.

[Function and effect]
In the final stage where the contact state between the projecting surface portion and the straight cylindrical portion continues, the inclined contact surface comes into contact with the inclined receiving surface. That is, a substantially constant tensile resistance is detected in a state where the projecting surface portion is in contact with the straight cylindrical portion. When this substantially constant tensile resistance is applied, if the inclined contact surface comes into contact with the inclined receiving surface, the tensile resistance suddenly increases and the large resistance is felt by the angler. It can be felt that the end position of is reached.
Accordingly, it is possible to prevent overdrawing in advance and prevent the sticking phenomenon from appearing.

According to a third aspect of the present invention, there is provided a swinging cage in which the inclined receiving surface and the inclined contact surface are in contact with each other, and the drawing state is stopped . layer constituted by a prepreg having a pull aligned arranged reinforcing fibers group, said prepreg having a pull aligned arranged reinforcing fiber group along a predetermined inclination angle with respect to the rod axis, the reinforcing fiber group of the prepreg This is because the prepreg having a group of reinforcing fibers arranged and arranged so as to be symmetric with respect to the saddle axis is superposed, and the operation and effect thereof are as follows.

[Function and effect]
The invention according to claim 3 has the same effects as the invention according to claim 2. In addition, the following operational effects can be obtained. That is, when the protruding surface portion and the straight cylindrical portion are in contact with each other and the state is maintained, if the operation of pulling out the small-diameter side housing from the large-diameter side housing continues, the inclined receiving surface and the inclined contact surface Abut and the pulled-out state is stopped.
In this case, the layer constituted by the prepreg having the reinforcing fiber group in which the inclined receiving surface and the inclined contact surface are aligned and aligned is arranged along the predetermined inclination angle with respect to the saddle axis. Since the prepreg having a fiber group, and the prepreg having the reinforcing fiber group arranged in a symmetric manner with respect to the saddle axis line and the reinforcing fiber group of the prepreg are configured to overlap, Resistant to not only the tensile force acting in the axial direction and the tensile force acting in the circumferential direction, but also the shearing force along the direction inclined with respect to the axial line and the circumferential direction. Peeling and plastic deformation of the mating portion can be suppressed.
In addition, since it is arranged in a state inclined in the circumferential direction as compared with that in which reinforcing fibers are arranged in the circumferential direction, it is easy to bend and has excellent dimensional absorbency. Even if it comes into contact with the contact surface and is received, it is not tightened strongly, and it is possible to suppress the occurrence of a sticking phenomenon.

  According to a fourth aspect of the present invention, there is provided a butt end portion of the rim end portion of the rim end portion while forming a rim end portion on the outer butt side of the inclined contact surface on the outer peripheral surface of the small diameter side skeleton. The projecting surface portion is erected, and the outer diameter at the bottom end portion of the housing is set to be smaller than the outer diameter of the bottom end of the inclined contact surface and the outer diameter of the projecting surface portion. There are the following effects.

[Function and effect]
In other words, in a state where the projecting surface portion is in contact with the straight cylindrical portion, the outer peripheral surface of the bottom end portion of the housing is straight from the outer diameter of the bottom end of the inclined contact surface or smaller than the outer diameter of the projecting surface portion. Neither the cylindrical part nor the inclined receiving surface comes into contact. Therefore, in a state in which the small-diameter side casing is pulled out from the large-diameter side casing, the projecting surface portion formed at the bottom end of the casing bottom end until the inclined contact surface comes into contact with the inclined receiving surface. Since only the straight cylindrical part is in contact with the straight cylindrical part, even if the drawing direction is slightly inclined with respect to the vertical axis, the contact state with the straight cylindrical part due to the inclined state only by deformation of the projecting surface part Therefore, the operability during the drawer operation is improved. Moreover, since the bottom end of the casing that supports the projecting surface at the position of the buttocks end has a small diameter, the number of cross-sectional shapes is small, and the body is affected by the reaction force received from the straight cylindrical part that contacts the projecting surface. The projecting surface portion located on the butt end side with the connecting position of the bottom end portion to the inclined contact surface as the base end portion is easily displaced in the radial direction like the tip portion of the cantilever. Therefore, even if there is a change in the diameter of the straight cylindrical part , the contact state of a predetermined surface pressure can be maintained by the displacement of the projecting surface part.

Characterizing feature of the invention according to claim 5, pull aligned layer constituted by a prepreg having arranged reinforcing fiber group of the rod body butt end, pull aligned disposed along a predetermined inclination angle with respect to the rod axis The prepreg having the reinforced fiber group, and the prepreg having the reinforced fiber group and the prepreg having the reinforced fiber group arranged so as to be symmetrical with respect to the saddle axis are overlapped. There are the following effects.

[Function and effect]
In other words, in a state where the projecting surface portion is in contact with the straight cylindrical portion, the outer peripheral surface of the bottom end portion of the housing is straight from the outer diameter of the bottom end of the inclined contact surface or smaller than the outer diameter of the projecting surface portion. Neither the cylindrical part nor the inclined receiving surface comes into contact. Therefore, it never receives a reaction force directly from the inclination supporting surface from straight-through cylindrical portion rod body butt end.
However, the reaction force that acts on the projecting surface formed at the bottom end of the bottom end of the casing affects the end of the bottom end of the casing. In this case, the surface layer of the butt end portion of the skeleton has a prepreg having a reinforcing fiber group that is aligned and arranged along a predetermined inclination angle with respect to the heel axis, and the reinforced fiber group of the prepreg and the heel axis Since the prepreg with reinforcing fiber groups aligned and arranged in a symmetrical state is overlapped, it only demonstrates the resistance to the load acting in the axial direction and the load acting in the circumferential direction. In addition, the reinforcing fibers arranged in a state inclined with respect to the saddle axis also exerts a counter force against a shearing force acting from a direction inclined with respect to the saddle axis, and resists loads from multiple directions. The power can be improved.
As a result, the strength of the bottom end of the casing that supports the projecting surface portion can be increased, so that the contact state of the projecting surface portion with the straight cylindrical portion is stabilized.

  A characteristic configuration of the invention according to claim 6 is that an inclined guide tube portion is formed between the straight cylindrical portion and a main body portion provided on the butt end side from the straight cylindrical portion, and in the inclined guide tube portion The diameter expansion degree that expands the inner surface diameter along the axial direction of the inclined guide surface is larger than the cylindrical surface of the straight cylindrical portion, and the inner surface diameter is increased along the axial direction of the inner peripheral surface of the main body portion. The function and effect are as follows.

[Function and effect]
In other words, since the inclined guide tube portion is provided, even if the projecting surface portion is located in the main body portion, it is eccentric with respect to the saddle shaft core and causes a positional deviation with respect to the straight cylindrical portion, When the projecting surface portion reaches the inclined guide tube portion, the projecting surface portion is guided along the inclined surface of the inclined guide tube portion before the projecting surface portion contacts the straight cylindrical portion, and the tilt guide of the inclined guide tube portion is provided. Since the diameter expansion degree of the surface is larger than the cylindrical surface of the straight cylindrical part and smaller than the diameter expansion degree of the inner peripheral surface of the housing main body part, the projecting surface part is displaced from the straight cylindrical part. You will be guided to correct it.
Therefore, since the contact state between the projecting surface portion and the straight cylindrical portion is adjusted to a constant pressure contact state, an operation of pulling out the small-diameter side housing from the large-diameter side housing can be easily performed.

  According to a seventh aspect of the present invention, there is provided a prepreg having a reinforcing fiber group in which the surface layer of the inclined guide tube portion is aligned and arranged along a predetermined inclination angle with respect to the saddle axis, and the reinforcing fiber of the prepreg The group and the prepreg having the reinforcing fiber group arranged so as to be symmetric with respect to the saddle axis are configured to overlap each other, and the operation and effect thereof are as follows.

[Function and effect]
That is, when the projecting surface portion is guided by the inclined guide tube portion and moves, the direction of the load that the projecting surface portion exerts on the inclined guide surface is not only orthogonal to the inclined guide surface, but also acts in an inclined state. It becomes a complicated load action form. On the other hand, the surface layer of the inclined guide tube portion is formed on the prepreg having reinforcing fiber groups arranged along a predetermined inclination angle with respect to the saddle axis, and the reinforcing fiber group of the prepreg and the saddle axis. Since it is composed of prepregs that have reinforcing fiber groups that are arranged in a symmetrical manner with respect to each other, the reinforced fiber exhibits resistance against loads acting from multiple directions, and the resin is peeled off. And plastic deformation is rare.
In addition, since the reinforcing fibers are arranged in the inclined state as described above, the flexibility is higher than the case where the reinforcing fibers are arranged in the circumferential direction, and the sticking phenomenon does not occur.

[First embodiment]
A configuration that is mainly applied to the intermediate rod from the second rod to the former in the swing rod A, particularly the middle rod from the fourth rod or the like will be described. The small-diameter side housing will be described as a small-diameter side housing 1, and the large-diameter side housing will be described as a large-diameter side housing 2.
Although not shown in the figure, the housing is manufactured as follows. In other words, reinforcing fibers such as carbon fibers are aligned in one direction, and the aligned reinforcing fibers are impregnated with a thermosetting resin (or thermoplastic resin) such as epoxy to form a prepreg. The prepreg cut into a predetermined shape is wound around a mandrel, the one formed in a plurality of layers is fired, fired, cut into a predetermined length, and finished to obtain a casing.
Glass fibers, aramid fibers, alumina fibers, etc. can be used as reinforcing fibers constituting the prepreg, and thermosetting resins such as phenol resins and polyester resins, and thermoplastic resins such as PET are used as resins. it can.

  The configuration of the small-diameter side housing 1 will be described. As shown in FIG. 1 (a), the small-diameter side housing 1 is formed with a conical inclined contact surface 1A whose diameter increases toward the buttock end on the outer peripheral surface of the buttock end, The bottom end 1B of the body is provided with a slightly inclined state (or maintaining the same diameter) on the side of the buttocks 1A of the contact surface 1A. It is.

As shown in FIG. 1 (c), the projecting surface portion 1 a is provided at three locations in the circumferential direction, and is formed of a prepreg in the same manner as the small-diameter side housing 1. That is, as shown in FIG. 2, the reinforcing fiber c group in which the surface layer contacting the straight cylindrical portion 2B described later of the projecting surface portion 1a is arranged along the axial direction of the small-diameter side casing 1 is impregnated with resin. Prepreg.

The structure in the surface layer in the inclined contact surface 1A and the housing bottom end 1B will be described. In FIG. 3, “the intermediate reinforcing pattern 7 is composed of a prepreg 7A having a group of reinforcing fibers c aligned with a predetermined inclination angle θ with respect to the saddle axis X, and a reinforcing fiber c group of the prepreg 7A and the saddle axis X. The prepreg 7B having the reinforcing fiber c group aligned and arranged in a symmetric state with respect to each other is configured to overlap , as shown in FIG. 2, the inclined contact surface 1A, and The alignment direction of the reinforcing fibers c in the prepreg in the cadaver butt end 1B is arranged in a state along the circumferential direction of the heel. With such a configuration of the reinforcing fibers c, the reinforcing fiber c exerts a counteracting force on the cross-section of the casing to become an elliptical shape that spreads horizontally, and prevents the wrinkles from being crushed due to the elliptical shape. It has become.

  The manufacturing process of the small-diameter side casing 1 having the above-described configuration is summarized as follows. As shown in FIG. 3, a plurality of main patterns 3 each having a prepreg cut to a length corresponding to the entire length of the casing 1 are wound around the mandrel 6. Here, the inner main pattern 3A, the intermediate main pattern 3B, and the outer main pattern 3C are wound with the direction of the reinforcing fibers set in the circumferential direction orthogonal to the axis X of the ridge, the direction along the axis X, and the circumferential direction, respectively. It is turned. The intermediate reinforcing pattern 7 is wound around the heel end portion of the heel material C formed by winding the main pattern 3. The intermediate reinforcing pattern 7 is symmetric with respect to the cocoon axis X and the prepreg 7A having the reinforced fiber c group that is aligned and arranged along the predetermined inclination angle θ with respect to the cocoon axis X. The prepreg 7B having the reinforcing fiber c group aligned and arranged in such a state is overlapped.

A prepreg tape 16 is wound around the outer layer side of the intermediate reinforcing pattern 7. That is, the intermediate layer is formed by tightly winding the prepreg tape 16 formed by arranging the reinforcing fibers c in the circumferential direction of the ridge and having a narrow width so that the tapes do not overlap each other and are in contact with each other. The outer reinforcing pattern 8 as a surface layer is wound around the outer peripheral surface of the heel end portion of the heel material C around which the prepreg tape 16 is wound. Outer reinforcing pattern 8 is composed of a wide width reinforcement pattern 8A, a narrow reinforcing pattern 8B are aligned drawn along the reinforcing fiber group c in the short width than the wide reinforcing pattern 8A to rod axis direction. The prepreg constituting the wide reinforcing pattern 8A includes a portion 8a that forms the inclined contact surface 1A and a portion 8b that forms the housing bottom end portion 1B. Portions 8b forming the rod body butt end 1B which definitive the prepreg wide width reinforcing pattern 8A has been cut in a substantially triangular shape by a plurality plies wound, and a smaller diameter than the inclined contact surface 1A The body bottom end 1B is formed. Thus, since the substantially triangular reinforcing prepreg is used to form the butt end 1B, the diameter of the butt end forming the projecting surface 1a is reduced to be easily deformed. The body bottom end 1B is formed.

The configuration of the large-diameter side housing 2 will be described. As shown in FIG. 1 (a), the inclination is smaller than the normal diameter expansion degree (about 5/1000) where the diameter increases toward the buttock side on the inner peripheral surface of the inclination receiving tube portion on the heel side. The inclined receiving surface 2A exhibiting (about 3.0 / 1000) is formed, and the inner diameter of the inclined receiving surface 2A is the same or substantially the same (0.3) from the butt end to the buttock side. / 1000) is formed, and is slightly larger than the diameter expansion degree of the inclined receiving surface 2A over a certain length from the butt end of the straight cylinder 2B toward the butt of the heel. An inclined guide cylinder portion having an inclined guide surface 2C having a small diameter expansion degree (about 2.55 / 1000) is provided, and further, a general inclination degree (5/1000 as a casing) on the buttock side from the inclined guide surface 2C. The main body 2F having a degree) is formed.
As described above, the inclined contact surface 1A and the projecting surface portion 1a of the small-diameter side housing 1 and the inclined receiving surface 2A and the straight cylindrical portion 2B constitute the mating portion B.

  As shown in FIG. 4, an inner peripheral surface is formed as a surface layer in a range extending from the inclined receiving surface 2 </ b> A, the straight cylindrical portion 2 </ b> B, and the inclined guide surface 2 </ b> C in the large-diameter side housing 2. The layer is constituted by an inner reinforcement pattern 9. The inner reinforcing pattern 9 is symmetric with respect to the heel axis X and the prepreg 9A having the reinforced fiber c group that is aligned with the heel axis X along the predetermined inclination angle θ. A prepreg 9B having a group of reinforcing fibers c aligned and arranged in a state is formed to overlap. Thus, by arranging the reinforcing fiber c group in the bias, the resistance force against the load applied from the direction inclined with respect to the saddle axis X can be increased, and the strength as the mating portion B can be improved.

  Three main patterns 3A, 3B, and 3C are sequentially wound around the mandrel 6 provided with the inner reinforcing pattern 9 to form a skeleton as the bag material C. Although the illustration of the process after winding the main pattern 3 is omitted, as shown in FIG. 3 described above, the intermediate reinforcing pattern 7, the prepreg tape 16 on the outer layer side of the intermediate reinforcing pattern 7, and An outer reinforcing pattern as a surface layer is wound around the outer peripheral surface of the heel end portion position of the heel material C formed by winding the prepreg tape 16. As the outer reinforcing pattern, the wide reinforcing pattern 8A of the outer reinforcing pattern 8 shown in FIG. 3 is selected, and the narrow reinforcing pattern 8B is not used, and is composed of one prepreg in which reinforcing fibers c are arranged in the circumferential direction. To do.

With the configuration as described above, when the small-diameter side casing 1 is housed in the large-diameter side casing 2 and pulled out to the extended state, the projecting surface portion 1a is first brought into contact with and guided by the inclined guide surface 2C. Then, the inclined guide surface 2C is transferred to the straight cylindrical portion 2B and inscribed in the straight cylindrical portion 2B. While the pull-out operation of the small-diameter side housing 1 is continued, the projecting surface portion 1a is inscribed in the straight cylindrical portion 2B, and an appropriate pull-out resistance is given to the pull-out operation, so that the fitting portion B starts to engage with the angler. Can be recognized.
When the drawing operation is further performed, as shown in FIG. 1 (b), the inclined contact surface 1A finally comes into contact with the inclined receiving surface 2A, so that the small-diameter side housing 1 suddenly becomes large. Withdrawal resistance acts, which is felt by the angler who pulls out and operates the small-diameter side frame 1, and the small-diameter side frame 1 is further prevented from being pulled out.
On the other hand, the housing bottom end 1B has a diameter smaller than the diameter of the inclined contact surface 1A and the diameter of the projecting surface 1a, so that the housing bottom end 1B contacts the straight cylindrical portion 2B. There is no excessive pulling resistance.

The above-described structure of the mating portion B has a high anti-adhesion effect as described above, and test data demonstrating the effect is shown in Table 1. A test apparatus for obtaining the data of Table 1 is shown in FIG. 5, and the small-diameter side casing 1 is fitted to the large-diameter side casing 2 to support the small-diameter side casing 1 by hanging. The fitting force between the small-diameter side housing 1 and the large-diameter side housing 2 is initially set to 5 kg.
The movement amount L of the large-diameter side casing 2 in a state where the weight Wh is dropped from the height H with respect to the large-diameter side casing 2 and is received by the receiving flange 2D formed on the large-diameter side casing 2. It was the above data that was measured.

The amount of movement of the weight Wh was changed stepwise from 50 mm to 150 mm, the amount of movement L was measured, and whether or not the weight Wh = 1 Kg could be returned to the initial state before dropping was measured. It is. That is, it was measured whether or not the large-diameter side housing 2 can be returned from the moved state to the initial state, and whether or not the large-diameter side housing 2 has fallen into the so-called fixed state. It can be seen that there was no difficulty and that it was possible to provide the mating portion B that hardly gets stuck.
The fishing rod used in the test, using a rod having a straight-cylindrical portion 2B of the present invention, the rod of the conventional product, as combined unit B, and a resin coating on the rear portion outer peripheral surface of the small diameter side rod body A spear having a portion formed by spraying a large number of resin protrusions and a prepreg in which a highly flexible thermoplastic resin disposed on the buttock side of the portion is arranged in a turtle shape is used.
◎ ・ ・ ・ ・ There is no sticking, it can be easily returned to the original state ○ ・ ・ ・ ・ It can be returned to the original state △ ・ ・ ・ ・ Since it is stuck, it can be finally restored by two people × ・ ・ ・ ・Sticking is too strong to return

Using the above drop tester, the required pulling force or returning force at the drop distance (50 mm to 150 mm) is measured, and the result is shown in FIG . According to this, in the product of the present invention, the return force is 30 kg or less at all drop distances (50 mm to 150 mm). Since the range that can be returned by one person's force is 50 kg or less, it can be determined that sticking has not occurred.
On the other hand, the conventional product (paint projection product) already requires 52 kg as a return force at a drop distance of 130 mm, which exceeds the limit that can be returned by one person, and requires countermeasures against sticking.

The following test was carried out to show the evaluation at the joint B of the above-described product of the present invention and the conventional product (paint projection product) .
In order to measure the movement resistance of the joint B between the product of the present invention and the conventional product (paint projection product), a machine (not shown) that measures the movement resistance by applying tensile force and return force is used. To do. The measurement results are shown in FIG. 6. According to the results, the difference between the tensile force and the return force is not significant, but the difference between the product of the present invention and the conventional product (paint protrusion product) is significant.

That is, in the product of the present invention, the inclined contact surface 1A comes into contact with the inclined receiving surface 2A after the projecting surface portion 1a comes into contact with the straight cylindrical portion 2B to provide resistance, and the small-diameter side casing is contacted. There is a stroke of about 26 to 27 mm until the drawing state of 1 stops.
On the other hand, in the above-mentioned conventional product (paint projection product), the contact is started from the position corresponding to 10 mm in the product of the present invention, and then the resistance gradually increases, and compared with the product of the present invention at the 26 to 27 mm position at the end of the stroke. As a result, the resistance to movement is 2 to 3 times, indicating that it is stuck.

Here, when the case of the product of the present invention is examined in detail, the moving resistance is maintained at a constant resistance of about 3 km from the stroke of about 10 mm to about 22 mm. This constant resistance portion can be thought of as a portion that appears as a result of maintaining the state where the projecting surface portion 1a is in contact with the straight cylindrical portion 2B from the inclined guide surface 2C , and is a feature of the product of the present invention. Can be evaluated as part. Based on the evaluation results as described above, it is recognized that the product of the present invention is also excellent in measures against sticking.

[Second Embodiment]
Here, the number of protrusions 1a is arbitrarily set at the butt end of the small-diameter side casing 1, but in FIG. 8, the four protrusions 1a are arranged at four locations in the circumferential direction. Show.
Even when only the projecting surface portion 1a is formed in this way, the projecting surface portion 1a is placed on the straight cylindrical portion 2B from the inclined guide surface 2C formed on the large-diameter side housing 2 to contact the angler. A good operational feeling during operation can be provided.

[Third Embodiment]
The state which changed the formation object of a projecting surface part and a straight cylindrical part is shown. As shown in FIG. 10 (a), an inclined contact surface 1A is formed on the outer peripheral surface of the butt end portion of the small-diameter side casing 1 in the same manner as in the first embodiment, and an outer surface diameter is formed on the butt end side. Is provided with a straight cylindrical portion 1C.
On the other hand, an inclined receiving surface 2A with which the inclined contact surface 1A contacts is formed on the inner peripheral surface of the flange tip portion of the large-diameter side housing 2, and inward toward the buttock side of the inclined receiving surface 2A. A projecting surface portion 2E is formed to protrude.

  When the small-diameter side casing 1 configured as described above is housed in the large-diameter side casing 2, first, the straight cylindrical portion 1C of the small-diameter side casing 1 comes into contact with the projecting surface portion 2E of the large-diameter side casing 2. . If the drawer operation is continued while maintaining the contact state between the straight cylindrical portion 1C and the projecting surface portion 2E, the inclined contact surface 1A comes into contact with the inclined receiving surface 2A as shown in FIG. It becomes impossible to do.
