Description

  According to the present invention, a rod tip side rod body and a rod origin side rod body are fished by a pressure contact state between a rod end end side mating part of the rod tip side rod body and a rod tip side mating part of the rod origin side rod body. The present invention relates to a fitting portion structure of a fishing rod configured to be switchable between a fixed state in which it is fixed in an operation state and a non-fixed state in which the press-contact state is released and separated into a non-fishing operation state.

  There has been a fishing rod having such a structure as follows. In other words, a rod-end end fitting part is formed at the rod-end end of the head rod as the rod-end rod body, and a rod-end side mating part is formed at the rod-end rod body as the rod-end rod body. There was one that constituted a pole (Cited Document 1).

In this product, a relatively thick prepreg sheet is lined on the inner peripheral surface of the rod base end side mating portion of the head rod, and the alignment direction of the reinforcing fibers of this reinforcing prepreg sheet is along the circumferential direction. Was set to something.
On the other hand, in the case of a rod having a rod, such a reinforcing prepreg sheet is not wound around the outer peripheral surface of the rod tip side joining portion, but a plurality of main prepreg sheets having a length of a rod body constituting the rod having a rod itself are used. Since it is wound in layers, the direction of the reinforcing fibers in the rod tip side mating portion is the direction of the reinforcing fibers of the main prepreg sheet, and the direction of the reinforcing fibers is aligned in the axial direction of the rod, or in the circumferential direction. It is considered that they are aligned (Patent Document 1).

In the case of the above-mentioned structure, since the reinforcing prepreg sheet is applied, the strength can be increased sufficiently against bending of a rod or the like, but there is one problem. That is, when the mechanism is cast, if the pressure contact state between the rod-end end side mating portion and the rod tip side mating portion is loose, the tip rod may jump out of the ear-holding rod and separate therefrom.
On the other hand, in order to solve such a problem, if the surface accuracy for both mating parts is further increased by using reaming or centerless processing, it will be too tight this time, and it will be necessary to finish the fishing and prepare for the end At the same time, the head rod could not be pulled out of the head rod, and it was difficult to finish the process.

  However, there is a type of a main prepreg sheet in which reinforcing fibers are inclined with respect to the rod axis as a main prepreg sheet wound around a mandrel as an ear-holding rod. In this one, the small-diameter side rod body is a solid rod-shaped body, and a bundle in which many reinforcing fibers are aligned in the rod axis direction is impregnated with resin and solidified, and the surface extends along the rod axis direction. Reinforcing fibers are exposed (Patent Document 2).

  As described above, in the case where the reinforcing fibers of the small-diameter side rod body are aligned in the rod axis direction, the popping-out phenomenon as described above cannot be prevented, and an adhesive is also applied. I have. Then, as described above, the problem that the fixed state cannot be released during the closing process has not been solved.

  It is an object of the present invention to provide a fishing operation while preventing the so-called 'slip-out phenomenon' in which the rod-end-side rod body slips from the rod-end-side rod body even during the swinging operation of a gimmick or the like during fishing operation. It is an object of the present invention to provide a fitting portion of a fishing rod that can easily separate a rod-side rod body and a rod-side rod body when preparing for return.

〔Constitution〕
The characteristic configuration of the invention according to claim 1 is that the rod tip side rod body and the rod origin side rod body are aligned with the rod end end side alignment portion of the rod tip side rod body and the rod tip side rod body of the rod origin side rod body. A fixed state in which the fishing operation state is fixed by the pressure contact state with the part, and a non-fixed state in which the pressure contact state is released and the non-fishing operation state is separated, so as to be switchable, and the rod base end side mating part and the A prepreg having reinforcing fibers aligned in a direction inclined with respect to the rod axis is disposed on the surface of the rod tip side mating portion, and the reinforcing fibers of the rod base end side mating portion surface and the rod tip side mating portion surface And the reinforcing fibers are set in the same inclination direction, and the included angle Θ between the rod axis and the reinforcing fibers is set to 45 ° ≦ Θ <90 °. The operational effects are as follows. It is.

[Action]
That is, since the reinforcing fibers on the surface of the rod base end side mating portion and the reinforcing fibers on the surface of the rod tip side mating portion are set in the same inclination direction, the reinforcing fibers on both mating portions have the same function as the thread. When both are relatively rotated in one direction, the pressure contact state of both mating portions is tightly tightened, and when the two are relatively rotated in the opposite direction, they are loosened to the non-pressure contact side.
In particular, since the sandwiching angle す between the rod axis and the reinforcing fiber of the prepreg is set to 45 ° ≦ Θ <90 °, the reinforcing fiber of the prepreg separates from the rod axis, that is, rises from the rod axis. And the meshing between the reinforcing fibers at both mating portions becomes good.
By this, at the time of the fishing operation, the tightening, the slip-on phenomenon, and the circumferential displacement due to the torque on the fishing line guide at the time of tackling are suppressed. Can be easier.

〔effect〕
Therefore, by applying a slight relative rotation operation to the rod tip side rod body and the rod base side rod body, a mating portion structure of the fishing rod that can easily cope with both the fishing operation and the non-fishing operation. We can provide it.

〔Constitution〕
The feature configuration of the invention according to claim 2 is that the rod tip side rod body and the rod origin side rod body are aligned with the rod end end side alignment portion of the rod tip side rod body and the rod tip side alignment part of the rod origin side rod body. A fixed state in which the fishing operation state is fixed by the pressure contact state with the part, and a non-fixed state in which the pressure contact state is released and the non-fishing operation state is separated, so as to be switchable, and the rod base end side mating part and the A prepreg having reinforcing fibers aligned in a direction inclined with respect to the rod axis is arranged on one surface of the rod tip side mating portion, and the other of the rod base end side mating portion and the rod tip side mating portion On the surface of the non-woven fabric, and the pinch angle の between the rod axis and the reinforcing fibers of the prepreg is set to 45 ° ≤ Θ <90 °, the effect of which is It is as follows.

(Effects)
The meshing of both reinforcing fibers is not as in claim 1 because one is a non-woven fabric, but the fitting state of both mating parts is switched when the rod tip side rod body and the rod base side rod body are relatively rotated. Is the same as in the first aspect.
Therefore, by applying a slight relative rotation operation to the rod tip side rod body and the rod base side rod body, a mating portion structure of the fishing rod that can easily cope with both the fishing operation and the non-fishing operation. We can provide it.

〔Constitution〕
A characteristic configuration of the invention according to claim 3 is that the rod tip side rod body is a solid rod-shaped or hollow cylindrical small diameter tip side rod body located on the rod tip side, and wherein the rod base side rod body is a rod base side. Is a hollow cylindrical large-diameter ear rod body located in
(A) A joint type rod body in which the rod base end side mating portion of the small diameter ear tip side rod body is fitted into the rod tip side mating portion of the large diameter ear holding rod body to create a fixed state. And (c) a reverse-joint type rod body that fits the rod tip side mating portion of the large-diameter ear tip rod body into the rod base end side mating portion of the small-diameter ear tip rod body to create a fixed state. The rod tip side mating portion, or the rod base end side mating portion is a spigot core material having an inclined outer peripheral surface, and a spigot splicing type that creates a fixed state by fitting the spigot core material to the mating side mating portion. The effect is as follows because the rod body is formed.

(Effects)
Due to its structure, the connecting rod, the reverse connecting rod, and the spigot rod, due to their structure, are required to fit one of the rod tip end fitting part of the rod tip side rod body and the rod tip side fitting part of the rod base side rod body. This is a method of inserting and fitting into the other mating portion. For this reason, when the fitting force between the mating portions is weak, the “slip-out phenomenon” easily occurs as described above.
However, as described above, the improvement is made such that the direction of the reinforcing fiber is inclined with respect to the axis of the rod, and the included angle Θ between the axis of the rod and the reinforcing fiber of the prepreg is set to 45 ° ≦ Θ <90 °. As a result, it is possible to effectively suppress the occurrence of the 'slip-out phenomenon'. In addition, at the time of closing, the loosening operation can be performed only by making a relative rotation in the opposite direction, and in this regard, a useful fishing rod fitting structure can be provided.

〔Constitution〕
The characteristic configuration of the invention according to claim 4 is that, in one of the rod base end side mating portion and the rod tip side mating portion, an inclined outer peripheral surface is formed, and the rod base end side mating portion and the rod tip side mating portion are formed. To form an inclined inner peripheral surface on the other side,

The rod tip side mating portion, or the rod base end side mating portion is a spigot core material having an inclined outer peripheral surface, and a spigot splicing type that creates a fixed state by fitting the spigot core material to the mating side mating portion. The effect is as follows because the rod body is formed.

(Effects)
Since the inclined surface structure is introduced in the joint portion of the two as described above, the structure of the reinforcing fiber of the present invention is further improved in a configuration in which the contact area of the both joint portion is increased to improve the connection between the two. By introducing the configuration with care in the inclination direction, the occurrence of the 'slip-out phenomenon' can be further suppressed.
Furthermore, since the inclined surface structure is introduced, even if the relative rotation is made in the opposite direction, even if the rotation angle is slight, the contact surface of both mating portions is immediately separated, so that the fishing rod mating portion structure is easy to finish. Can be provided.

〔Constitution〕
A characteristic configuration of the invention according to claim 5 is that the rod tip side rod body is a hollow cylindrical small diameter tip side rod body located on the rod tip side, and the rod origin side rod body is located on the rod origin side. It is a cylindrical large-diameter ear-holding rod body, and has a rod-end end-side mating portion on the outer peripheral surface of the rod-end end of the small-diameter ear tip-side rod body and an inner peripheral surface of a rod tip end of the large-diameter ear-holding rod body. A rod tip side mating portion is formed, and the small diameter tip side rod body is pulled out from the large diameter ear holding rod body, and an outer peripheral surface of the rod base end side mating portion is pressed against an inner peripheral surface of the rod tip side mating portion. The swing-out type rod body that forms the fixed state is formed by the above-described operation, and the operation and effect thereof are as follows.

(Effects)
In the swing-out rod body, the rod end side rod body is inserted from the rod end side open end of the rod end side rod body, pulled out from the rod end side open end, and the rod end end side mating portion of the rod end side rod body is inserted. Since the fixed state for fishing operation is created by being fitted inside the rod tip side mating part of the rod base side rod body, it seems that 'slip-out phenomenon' is relatively small, but during fishing operation In addition, since the rod body on the rod tip side moves toward the rod tip side with respect to the rod body on the rod base side, the fitting force between the mating parts increases as the use progresses. Then, the closing process involves difficulty, but even in such a case, the sticking phenomenon of the joining portion can be canceled by performing relative rotation in the opposite direction, and the closing process can be performed reliably.

〔Constitution〕
The characteristic configuration of the invention according to claim 6 is that, in the rod tip side rod body and the rod base side rod body, the rod base end side mating part and the rod tip side mating part are set in a specific relative positional relationship. The effect of this is that it forms an index indicating that the operation has been performed.

(Effects)
Since the indicators are provided in this manner, the current relative positional relationship between the rod base end side mating portion and the rod tip side mating portion can be immediately visually observed, and it is easy to create a fixed state or a non-fixed state. .
From the viewpoint that the guide can be seen, it can be grasped by the presence of the guide. However, when there is no guide near the rod base end side fitting part and the rod tip side fitting part, it is difficult to use the guide as an index.
In addition, when adjusting to a fixed state or the like, if the rotation direction with respect to the rod body or the like is incorporated as an index, a friendly design that is very easy to use is obtained.

The joining portion 1C is formed. The included angle Θ between the reinforcing fiber c and the rod axis X is in the range of 45 ° ≦ Θ <90 °. Preferably, it is in the range of 50 ° <Θ <70 °.

  Next, a manufacturing process of the rod base side rod body 2 will be described from the structure of the mandrel 3. As shown in FIGS. 2A and 2B, the mandrel 3 includes a rod-side mandrel 3A and a rod-side mandrel 3B. The mandrel 3 is generally formed of a steel material such as steel, stainless steel, titanium or the like into a substantially truncated cone shape, and is formed by applying a surface coating by chrome plating or the like.

The pole tip side mandrel portion 3A has a pipe shape extending from the tip end to the base end, and is formed in a substantially truncated cone shape having an inverted tapered surface whose outer diameter gradually decreases. The rod base side mandrel portion 3B has a columnar shape extending from the front end to the base end, and is formed in a substantially truncated cone shape having a positive tapered surface whose outer diameter gradually increases.
A spigot core portion 3b is formed at the tip end of the rod-side mandrel portion 3B, and can be engaged in the original engagement hole 3a utilizing the pipe-shaped internal space of the rod-side mandrel portion 3A. It is formed in.

The insertion engagement is completed in a state where the stepped portion 3d formed on the base contacting the original opening end 3c of the rod tip side mandrel portion 3A, and the mandrel 3 is integrally formed. This state is shown in FIG.
Holes 3e and 3f for tool locking are formed at the tip of the rod of the rod tip side mandrel 3A and the rod end of the rod base side mandrel 3B.
A hook locking tool is attached to the tool locking holes 3e, 3f, and the rod tip side mandrel 3A and the rod base side mandrel 3B are separated by using a drawing cylinder or the like.

  As shown in FIG. 4, the rod-side rod body 2 includes an innermost layer 2A, an inner tape layer 2B on the outer side, an intermediate sheet layer 2C on the outer side of the inner tape layer 2B, and an outer tape layer 2D on the outer side. Formed and configured. Outside the outer tape layer 2D, reinforcing layers 2E are provided on the rod tip side and the rod base side.

The innermost layer 2A is provided only for a certain length from the rod tip side end, and has a reverse tapered surface 2a inwardly reduced in diameter toward the rod base side and a positive taper expanded from the base side of the reverse tapered surface 2a further toward the base side. It has an inner peripheral surface composed of the surface 2b.
The innermost layer 2A winds a prepreg sheet 4 made of glass reinforced fiber in a certain range between the reverse tapered inner peripheral surface side and the forward tapered inner peripheral surface side.

As shown in FIG. 2C, the prepreg sheet 4 is prepared by aligning glass reinforcing fibers d in a direction inclined with respect to the rod axis X, impregnating with an epoxy resin or a PET resin, and cutting the prepreg into sheets. is there.
The rod-side end 4a of the prepreg sheet 4 made of glass-reinforced fiber is cut in a direction perpendicular to the rod axis X, and the rod-side end 4b is inclined from a direction perpendicular to the rod axis X. It has been cut. The remaining two sides form a side parallel to the rod axis X.
As described above, the prepreg sheet 4 made of glass reinforced fiber is formed on the rod tip side fitting portion 2F of the rod side rod body 2. The included angle Θ between the reinforcing fiber d and the rod axis X is in the range of 45 ° ≦ Θ <90 °. Preferably, it is in the range of 50 ° <Θ <70 °. Therefore, the inclination angle and the inclination direction of the surface reinforcing fiber of the rod-end-side mating portion 1C of the rod tip side rod body 1 with respect to the rod axis X are made to coincide.

The configuration of the prepreg sheet 4 may be as follows.
(A) A bias type in which a sheet in which glass reinforcing fibers d are aligned in the direction inclined with respect to the rod axis X and a sheet in which the glass reinforcing fibers d are aligned in the direction inclined in the opposite direction with respect to the rod axis X are overlapped. May be.
(B) The prepreg sheet 4 made of glass reinforced fiber impregnates the epoxy resin or PET resin into a cross fiber obtained by weaving the glass reinforced fiber d in a state of being inclined with respect to the rod axis X and intersecting the fiber. The sheet may be cut into sheets.
(C) The sheet may be configured by changing the glass reinforcing fibers d to carbon reinforcing fibers c.
As shown in FIG. 2D, a state in which the rod-side end side 4a of the glass reinforced fiber prepreg sheet 4 cut as described above is aligned with the rod-side mandrel portion 3A of the mandrel 3 as shown in FIG. To wind. The prepreg sheet 4 made of glass-reinforced fiber has a reverse tapered outer peripheral surface with a connection point between a reverse tapered outer peripheral surface of the rod tip side mandrel portion 3A and a forward tapered inner peripheral surface of the rod base side mandrel portion 3B as a reference point. And a certain range extending over the positive tapered outer peripheral surface side.

Next, the inner tape layer 2B will be described. As shown in FIG. 2 (e), what is used in the inner tape layer 2B is a narrow inner prepreg tape 5 in which a plurality of carbon reinforcing fibers are arranged in parallel along the tape longitudinal direction. , And impregnated with epoxy resin or the like to form a prepreg tape.
The inner prepreg tape 5 is spirally wound from the innermost layer 2A wound around the mandrel 3 and sequentially from the rod side to form the inner tape layer 2B.

Next, the intermediate sheet layer 2C is formed. As shown in FIG. 3F, the intermediate prepreg sheet 6 having a substantially elongated trapezoidal shape forms the intermediate sheet layer 2C. The intermediate prepreg sheet 6 is a sheet obtained by impregnating an epoxy resin or the like with carbon reinforcing fibers c arranged in parallel in the rod circumferential direction and in the rod axial direction and intersecting, and cut into a sheet shape.
The above-mentioned prepreg sheet 6 is cut so that the rod end side edge 6A and the rod base side edge 6B are orthogonal to the rod axis X, and is wound first on the inner tape layer 2B. The end side 6C is cut substantially in parallel to the rod axis X, and the winding end end 6D is cut into a straight line away from the rod axis X toward the base of the rod. At the intersection of the rod tip side edge 6A and the winding start edge 6C orthogonal to the rod tip side edge 6A, both the rod tip side edge 6A and the winding start edge 6C are oblique. The cutting surface 6a is formed so that the cutting surface 6a is separated from the rod axis X toward the rod tip side edge 6A.

The notch formed by the cutout surface 6a in the shape of the intermediate sheet layer 2C on the rod tip side is provided because the innermost layer 2A is provided in a certain range between the reverse tapered inner peripheral surface side and the forward tapered inner peripheral surface side. When the intermediate sheet layer 2C is wound on the inner tape layer 2B, as shown in FIG. 3 (g), the tapered shape of the outer peripheral surface is increased toward the original side. It is in order to make a state.
The configuration of the prepreg sheet 6 may be as follows.
(A) A bias type in which a sheet in which reinforcing fibers c are aligned in the rod circumferential direction and a sheet in which the reinforcing fibers c are aligned in the rod axis direction may be overlapped.
(B) It may be constituted only by a sheet in which the reinforcing fibers c are aligned in the rod circumferential direction.
(C) The reinforcing fiber c may be constituted only by a sheet in which the reinforcing fibers c are aligned in the rod axis direction.
(D) The reinforcing fiber c in a state inclined with respect to the rod circumferential direction and the reinforcing fiber c in a state inclined with respect to the rod axis direction may be formed by a sheet in which the reinforcing fibers c are interwoven with each other.

Next, the outer tape layer 2D will be described. As shown in FIG. 3 (h), what is used in the outer tape layer 2D is a narrow outer prepreg tape 7 in which a plurality of carbon reinforcing fibers c are arranged in parallel along the tape longitudinal direction. And a prepreg tape impregnated with epoxy resin or the like.
The outer tape layer 2D is formed by sequentially winding the outer prepreg tape 7 spirally from the tip of the intermediate sheet layer 2C wound around the mandrel 3 on the rod tip side.

The inner prepreg tape 5 and the outer prepreg tape 7 are both wound in a state of being inclined with respect to the rod axis X and in a spiral shape, but their winding directions are opposite to each other and cross each other. Is wrapped around. This makes it possible to form a high-strength, particularly torsion-resistant rod body as the rod-side rod body 2.
The winding start position of the inner prepreg tape 5 and the outer prepreg tape 7 can be selected on either the pole tip side or the rod base side and is arbitrary. In short, it is only necessary that the inner prepreg tape 5 and the outer prepreg tape 7 are wound in opposite directions.
As a winding form of each of the inner prepreg tape 5 and the outer prepreg tape 7, adjacent narrow widths (tape widths) spirally wound are partially overlapped or closely contacted, or It may be in a state where a gap is slightly opened.

After the outer prepreg tape 7 is wound, as shown in FIG. 2 (h), a reinforcing prepreg 8 having a short axial center length is wound around the rod tip and the rod base end. The reinforcing prepreg 8 is made of a cross fiber woven with the reinforcing fibers c intersecting. The reinforcing layer 2E is composed of the reinforcing prepreg 8 disposed at the rod tip and the rod base end.
However, although not illustrated, a bias type in which two prepregs in which the reinforcing fibers c are aligned in one direction are aligned and the reinforcing fibers c intersect each other may be used.

After winding the reinforcing prepreg 8, although not shown, the winding tape is wound outward, the mandrel 3 is fired together, and the mandrel 3 is removed, and then the winding tape is peeled off.
Then, the rod-side mandrel 3A is pulled out to the rod-side and the rod-side mandrel 3B is pulled out to the rod-side by a cylinder (not shown) linked through the holes 3e and 3f for tool locking. Then, the rod body and the mandrel 3 are separated. Then, the rod is formed by cutting it to a predetermined coating and a predetermined length.
As described above, even in the case of the rod body having the inverted tapered surface 2a, the reinforced fibers c and d are cut without the need for the reaming process by employing the manufacturing method in which the rod-side mandrel portion 3A is pulled out to the rod-side. Therefore, it is possible to obtain a smooth inner peripheral surface in which the resin surface is not roughened.

  Incidentally, as shown in FIG. 1, the reinforcing fiber d of the rod tip side prepreg sheet 4 constituting the rod tip side joining portion 2F of the pole tip side rod body 2, and the rod tip end side joining portion of the rod tip side rod body 1. The reinforcing fiber c of the rod base end side prepreg sheet 9 constituting 1C has the same inclination angle (angle between the rod axis X and the reinforcing fiber) Θ with respect to the rod axis X and the same direction in the circumferential direction. It is configured to draw a spiral. The pitch of the reinforcing fibers in the axial direction is determined by a male screw and a male screw in a state where the rod end end fitting portion 1C of the rod tip side rod body 1 and the rod tip side fitting portion 2F of the rod end side rod body 2 are fitted. Like a female screw, it is desirable that the peaks and the valleys mesh with each other at the same pitch, but it is not always necessary.

The fitting force at the time of fixing was measured by combining the rod tip side fitting portion 2F of the rod base side rod body 2 formed as described above and the rod base end side matching portion 1C of the rod tip side rod body 1. . FIG. 8 shows the result.
(1) As shown in FIG. 8 (a), in a state where the rod tip side fitting portion 2F of the rod side rod body 2 and the rod base end side matching portion 1C of the rod tip side rod body 1 are loosely combined, The weight W is pushed in by a predetermined amount l ₁ = about 10 mm to set a proper alignment state.
(2) Next, as shown in FIG. 8 (b), the tension measuring device 10 is attached to the tip of the rod tip side rod body 1 and the rod tip side of the rod tip side rod body 2 is placed at the rod tip side. The measurement is performed by mounting a relative angle measuring device 14 for measuring a relative rotation angle of the rod body 2 and the rod tip side rod body 1 in the circumferential direction.
(3) The rod tip side alignment portion 2F of the rod end side rod body 2 and the rod end end side alignment portion 1C of the rod end side rod body 1 are loosely and firmly fitted (fixed state). A loose fitting state (non-fixed state) and an intermediate state between the two are set as reference states. By rotating about 30 ° in one direction from the reference state (ie, + 30 °), the loose fitting state can be set, and by rotating about 30 ° in the opposite direction from the reference state (ie, -30 °), the strong fitting state (unfixed) State) can be set.
(4) Then, the fitting force against pulling in a state of being rotated by + 30 ° and −30 ° from the reference state was measured.
(5) Incidentally, the configuration of the product of the present invention is such that the reinforcing fiber d and c are both wound on the rod tip side fitting portion 2F of the rod side rod body 2 and the rod base end side matching portion 1C of the rod tip side rod body 1. The turning directions are the same and the inclination angle (inclination with respect to the axis) Θ = 60 °. On the other hand, in the case of the conventional product, both the rod tip side alignment portion 2F of the rod end side rod body 2 and the rod end end side alignment portion 1C of the rod tip side rod body 1 are in the direction along the axis X (the inclination with respect to the axis). ) Θ = 0 °.
(6) The results of the test performed as described above are shown in FIG. According to the test results, according to the invention, the fitting force (138, 6N) is more than twice that of the conventional product in the strong fitting state, and the pulling force is about 60% of the conventional product in the loose fitting state. This shows that the rod-side rod body 1 can be separated from the rod-side rod body 2. The relative rotation torque required for relative rotation when switching from the reference state to the strong fitting state requires about 1,5 times the torque required for the relative rotation compared to the conventional product. I can do it.

Next, a description will be given of indices that assist in switching from the above-described reference state to a strong fitting state (fixed state) and a loosely fitting state (non-fixed state).
As shown in FIG. 11, a rod-end end fitting portion 1 </ b> C is provided on each of the outer peripheral surfaces of the rod-end end fitting portion 1 </ b> C of the rod-end side rod body 1 and the rod tip-end fitting portion 2 </ b> F of the rod end side rod body 2. An index 13 is provided to indicate that the rod and the rod tip side mating portion 2F are set in a specific relative positional relationship.

  As the index 13, a black circle is employed as shown in FIG. Alternatively, a configuration may be adopted in which the thin wires 13A extend from the black circle 13 toward each other, and the thin wires 13A coincide with each other at the rod tip of the rod-side rod body 2.

The following is a case where the index 13 indicates that a specific relative positional relationship has been set.
(A) The index 13 indicates a strong fitting state (fixed state).
(B) The index 13 indicates a loosely fitted state (non-fixed state).
(C) The index 13 indicates the reference state.
Although a black circle is used as the index 13, various symbolic figures and the like can be described.

In the above case, the simple configuration with the black circle 13 is shown, but as shown in FIG. 11B, an arrow 13B indicating the rotation operation direction and a description 13C may be added.
This would make operation easier. LOCK (with parentheses) indicating a fixed state and RELEASE (with parentheses) indicating a non-fixed state are given as explanatory texts.
Here, a circle 13 indicates a reference state, and a fixed state can be obtained by performing a relative rotation in the LOCK direction and a twisting operation. On the other hand, when it is relatively rotated in the RELEASE direction and twisted, a non-fixed state can appear.
