Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod body constituting a fishing rod, and more particularly, to a rod body composed of a prepreg material obtained by impregnating a reinforcing fiber such as carbon fiber or glass fiber with a synthetic resin, and a rod body. Regarding manufacturing method.

[0002]

2. Description of the Related Art The rod body of a fishing rod used for fishing is generally
Manufactured by impregnating a reinforcing fiber called prepreg with a synthetic resin such as epoxy resin and processing it into a sheet or tape, winding the prepreg material around a core, and firing this.
The rod body manufactured from such a prepreg material is light, has excellent physical strength, and has appropriate flexibility,
It fully demonstrates the characteristics required of a fishing rod.

Generally, fishing rods are leisure and leisure items, and their appearances such as patterns and colors on the surface are required to have unique characteristics. Therefore, there is also provided a rod body in which a metal is vapor-deposited or applied on the peripheral surface of the rod body and metal plating is performed to produce luster and luster like metal.

[0004]

However, as is well known, when a fishing rod pulls the rod body during fishing, the fishing rod is largely bent, and a large bending force and the rod body are crushed in the circumferential direction. A force is applied in the direction. When such a force is applied to the rod body, fine cracks or cracks may occur on the peripheral surface of the rod body itself. And such fine cracks
The cracks are emphasized by the metal plating that gives off gloss on the peripheral surface, and there is a problem that cracks are noticeable in appearance when the fishing rod is used for a long period of time.

An object of the present invention is to provide a rod body capable of continuously producing a good gloss and color without any noticeable fine cracks or cracks on the surface even after long-term use.

[0006]

The rod body of the invention 1 is obtained by laminating a plurality of prepreg materials in which reinforcing fibers such as carbon fibers and glass fibers are impregnated with synthetic resin, and the outermost layer is reinforcing fibers of glass fibers. A rod body made of glass fiber prepreg impregnated with synthetic resin, a synthetic resin layer laminated on the peripheral surface of the rod body, a ceramic layer in which ceramic is physically vapor-deposited on the peripheral surface of the synthetic resin layer, and a peripheral surface of the ceramic layer. And a clear layer laminated on the.

In this rod body, the glass fiber prepreg, which is relatively rich in the elongation of the fiber itself, constitutes the outermost layer of the rod body, so that even if a large bending force or the like is applied to the rod body, cracking is less likely to occur. Even if cracks occur, it is more difficult to spread. On the other hand, the layer for improving the design of the peripheral surface of the rod body is formed by physical vapor deposition of ceramic having excellent hardness on the synthetic resin layer, and the possibility of cracking in itself is extremely small.

Further, in the manufacturing process of such a rod body, it is necessary to smooth the surface to be vapor-deposited in order to physically vapor-deposit ceramics on the rod peripheral surface, and to smooth the rod body peripheral surface with a synthetic resin layer. However, it is also necessary to carry out surface processing for polishing in order to smooth the peripheral surface of the rod body itself. At this time, since the peripheral surface of the rod body is made of glass fiber prepreg having a relatively low hardness, surface polishing is also facilitated.

The rod body of invention 2 is the rod body of invention 1,
The ceramic layer is metal nitride or metal oxide such as CrN, TiN, TiO ₂ . In this rod body, by providing a ceramic layer made of metal nitride or metal oxide such as CrN, TiN, TiO ₂ etc., it is possible to sufficiently enhance the strength of itself and to produce a beautiful luster and luster, and the design is sufficient. Will be improved.

The rod body of the invention 3 is the rod body of the invention 1 or 2, wherein the outer surface of the rod body is a carbon fiber prepreg in which carbon fibers are aligned in the circumferential direction, and a periphery laminated on the outer peripheral surface thereof. And a glass fiber prepreg having directional glass fibers.

The glass fiber prepreg is located on the outermost peripheral surface of the rod body of the rod body as described above. However, as is well known, the glass fiber is inferior in elastic modulus to the carbon fiber. Therefore, the rigidity of the rod body in the circumferential direction may be insufficient. Therefore, the carbon fiber prepreg, which is arranged adjacent to the inner periphery of the rod and has the carbon fibers aligned in the circumferential direction, sufficiently complements the circumferential rigidity of the rod body, which is somewhat uncomfortable with the glass fiber prepreg alone. It increases the rigidity of the body.

The rod body of the invention 4 is the rod body of the invention 3,
Glass fiber prepreg has an average thickness of 0.010 to 0.02
It is a thin prepreg material of about 0 mm. With this rod,
Since the predetermined carbon fiber prepregs are arranged adjacent to each other inside the glass fiber prepreg, the glass fiber prepreg itself does not need to be thickly laminated, and it suffices that the glass fiber prepreg exists as long as it can prevent fine cracks on the surface. Specifically, the glass fiber prepreg need only have a thickness within a predetermined range, which also contributes to weight reduction of the rod body itself.

The rod body according to the present invention is characterized in that a ceramic layer formed by physical vapor deposition of ceramic is provided on the outside of the rod body.

In such a rod body, since the ceramic layer is harder than metal, the ceramic layer is less likely to be scratched and is less likely to cause fine cracks or cracks. Moreover, it is possible to obtain a beautiful gloss and color as in the case of the metal layer. Therefore, good gloss and color can be maintained over a long period of use.

Further, when the rod body is formed by firing a fiber reinforced synthetic resin material containing carbon fibers as reinforcing fibers, a lower ceramic layer and an upper ceramic layer are provided outside the rod body. Preferably, the lower ceramic layer is provided so as to develop a monochromatic color, and the upper ceramic layer is provided so as to develop a rainbow color. The fiber reinforced synthetic resin material includes, for example, a prepreg material.

When carbon rods are included, the rod body becomes black due to the carbon fibers by firing, but in that case, a lower ceramic layer that separately develops a monochromatic color is provided inside the upper ceramic layer that develops rainbow colors. As a result, since the black rod body is covered with the lower ceramic layer, the iridescent color in the upper ceramic layer becomes better than in the case where the lower ceramic layer is not provided.

When the rod body is formed by firing a fiber-reinforced synthetic resin material containing carbon fibers as reinforcing fibers, the ceramic layer is provided outside the rod body with a black synthetic resin layer interposed therebetween. Is preferably provided. Only the carbon fiber part on the surface of the rod body may stand out especially black, but since the surface of the rod body is covered with the black synthetic resin layer, the ceramic layer is formed on a uniform black color. Therefore, good coloring of the ceramic layer is ensured without exhibiting a sparse pattern. The fiber reinforced synthetic resin material includes, for example, a prepreg material.

The method of manufacturing a rod body according to the present invention is characterized in that a ceramic layer is formed on the outside of the rod body by sputtering.

In the manufacturing method, since the ceramic layer is formed by sputtering, it is possible to easily form a ceramic layer having a uniform thickness as compared with other methods, for example, a method of forming by ion plating. You can If the thickness of the ceramic layer is not uniform, it will not be a good monochromatic ceramic layer, but since a ceramic layer of uniform thickness can be obtained by forming the ceramic layer by sputtering, a ceramic layer that emits a good monochromatic color can be obtained. Can be easily obtained.

In particular, it is preferable to use a metal nitride as the target and form a ceramic layer made of the metal nitride. When forming a ceramic layer made of metal nitride, it may be possible to form it by a reactive ion plating method in which a single metal that is not a nitride is reacted with nitrogen gas (reactive gas) to deposit a metal nitride. But,
It has been difficult to form a good ceramic layer of metal nitride by reactive ion plating. On the other hand, according to the sputtering using the metal nitride itself as a target, a ceramic layer made of a good metal nitride can be firmly formed to have a uniform thickness.

In that case, the ceramic layer of metal nitride can be formed at low cost by using the sintered body of metal nitride as the target.

BEST MODE FOR CARRYING OUT THE INVENTION [First Embodiment] A first embodiment of the present invention will be described below with reference to the drawings.

(Structure of Entire Fishing Rod) As shown in FIG. 1, the fishing rod adopting the first embodiment of the present invention is a cylindrical rod 1.
And a plurality of cylindrical inner rods 2 and 3 which are sequentially connected to the tip side of the base rod 1 in a swinging manner, and an ear rod 4 which is connected to the tip side of the inner rod 3. These 1 to 4 rods
As described later, is a tapered tapered tubular member formed of a prepreg sheet / prepreg tape made of carbon fiber reinforced resin, glass fiber reinforced resin, or the like.

A butt plug 9 is detachably fitted to the end of the base rod 1 on the rod base side, and a reel seat 5 on which a reel can be detachably mounted is provided on the peripheral surface. The fishing rod described in this embodiment is a so-called centering rod, and a fishing line introducing port 6 for introducing the fishing line from the reel into the rod body is formed on the tip side peripheral surface of the reel sheet 5 of the original rod 1. A fishing line introducing guide 7 for guiding the fishing line into the fishing line introducing port is arranged on the peripheral surface thereof.

On the other hand, a top guide 8 is connected to the tip end side of the tip rod 4, and the fishing line guided from the fishing line introducing port 6 to the inside of the rod body is sequentially sent to the tip side to be outside the top guide 8. Will be derived.

(Structure and Manufacturing Method of Middle Rod 2) The structure and manufacturing method of each rod body will be described by taking the middle rod 2 as an example. Figure 2
As schematically shown in Fig. 2, the middle rod 2 is made of carbon fiber reinforced resin obtained by impregnating carbon fiber with synthetic resin such as epoxy resin,
It is a tubular member formed by sequentially laminating and firing prepreg sheets and prepreg tapes made of glass fiber reinforced resin or the like in which glass fibers are impregnated with a synthetic resin such as epoxy resin, and then firing and integrating them. Then, ceramics are physically vapor-deposited on the peripheral surface. Specifically, a rod body 10 composed of a plurality of prepreg sheets / prepreg tapes, a synthetic resin layer 11 laminated on the peripheral surface of the rod body 10, and a ceramic layer 12 physically vapor-deposited on the peripheral surface of the synthetic resin layer 11. And a clear layer 13 laminated on the peripheral surface of the ceramic layer 12.

The structure of the rod body 10 will be described in more detail in the manufacturing method described later.
And an outer surface layer 16 laminated on the peripheral surface of the main body base layer 15. The outer surface layer 16 further includes a carbon fiber prepreg layer 17 and a glass fiber prepreg layer 18.

The synthetic resin layer 11 is a layer for smoothing the peripheral surface of the rod body 10 and facilitating physical vapor deposition of the ceramic layer 12, and is made of, for example, an epoxy resin or a urethane resin. The synthetic resin layer 11 (base coating) is not limited to a single-coating single layer, and may be a multi-coating multilayer.

The ceramic layer 12 is formed by closely laminating a ceramic such as a metal nitride or a metal oxide such as CrN, TiN, TiO ₂ or the like on the above-mentioned synthetic resin layer 11 by a known physical vapor deposition method such as sputtering or ion plating. It was made. Compared to the case of using a simple metal that has not been nitrided or oxidized, the use of a ceramic material excels in strength and durability. That is, as compared with the case where a layer made of a metal that is not nitrided or oxidized is provided, the ceramic layer 12
Has an advantage that it is hard to be scratched and is unlikely to cause fine cracks or cracks. Moreover, it is possible to obtain a beautiful gloss and color development as well as a layer made of a metal, and it is possible to produce a good gloss and color, which is also excellent in design. The clear layer 13 is a transparent or semi-transparent synthetic resin layer for protecting the ceramic layer 12, and may have an appropriate color if necessary. The clear layer 13 (top coat) is not limited to a single-coating single layer, and may be a multi-coating multi-layer.

Next, the structure of the rod body 10 will be clarified while sequentially explaining the method of manufacturing the rod body 10. As shown in FIG. 3A, a tapered cylindrical mandrel (core material) 50 is prepared, and a peripheral surface thereof is coated with a release agent or the like as necessary. Then, for example, the reinforcing prepreg 51 is partially wound around the tip side end portion of which the diameter is reduced and other portions where reinforcement is required.
The reinforcing prepreg 51 is a prepreg in which reinforcing fibers of either carbon fiber or glass fiber are aligned in the circumferential direction of the mandrel 50.

Next, as shown in FIG. 3B, a tape-shaped prepreg tape 52 is formed on the outer periphery of the mandrel 50 and the reinforcing prepreg 51 in a spiral shape with no gap in the axial direction.
To wind. For example, this prepreg tape 52 has a tape width of 5 to 8 mm in which carbon fibers are aligned in the longitudinal direction of the tape.
The tensile modulus of the carbon fiber is 24 to 50.
It is preferably about t / mm ² .

As shown in FIG. 3C, a prepreg sheet 53 is further wound around the outer circumference of the prepreg tape 52 wound. A plurality of prepreg sheets 53 are sequentially wound as needed. The prepreg sheet 53 is, for example, one in which carbon fibers are aligned in the axial direction of the mandrel 50, and has a tensile elastic modulus of carbon fibers which is larger than that of the prepreg tape 52 described above.
It is preferably about t / mm ² . When a plurality of prepreg sheets 53 are wound, the characteristics of carbon fibers of each wound prepreg sheet 53 may be different. Each of the prepreg tape sheets thus far constitutes the main body base layer 15 of the rod main body 10 schematically shown in FIG.

As shown in FIG. 3D, a prepreg tape 54 in which carbon fibers are aligned in the longitudinal direction of the tape is further spirally wound around the outer circumference of the prepreg sheet 53 thus wound. To do. This prepreg tape 54
Like the above prepreg tape 52, the width is about 5 to 8 mm, and the tensile modulus of the carbon fiber is preferably about 24 to 30 t / mm ² which is relatively small. The prepreg tape 54 is the outer surface layer 1 schematically shown in FIG.
The carbon fiber prepreg layer 17 of No. 6 is obtained.

As shown in FIG. 3 (e), a glass prepreg sheet 55 in which glass fibers are woven in both the circumferential direction and the axial direction of the mandrel 50 is further wound around the outer periphery thereof. The glass fiber of the glass prepreg sheet 55 has a tensile elastic modulus smaller than that of carbon fiber and is about 6 to 8 t / mm ² . It is preferable that the content of the synthetic resin is relatively small, for example, the content rate of the synthetic resin is 20 to 30%.
It is of a degree. Also, the glass prepreg sheet 55
Is preferable to be relatively thin to reduce the weight,
It is preferable to use one having an average thickness of about 0.010 to 0.020 mm. And this glass prepreg sheet 55
Becomes the glass prepreg sheet layer 18 in FIG.
Instead of the glass prepreg sheet 55, a tape-like prepreg tape obtained by slitting the same glass prepreg sheet into a width of about 5 to 8 mm may be wound like the prepreg tapes 52 and 54.

After the respective prepreg sheet tapes are sequentially wound in this way, as shown in FIG. 3 (f), a reinforcing prepreg 56 is further partially wound around a necessary portion, and polypropylene and polyester are wound around the outer circumference thereof. A molding tape 57 made of a synthetic resin such as the above is wound while helically applying tension. The reinforcing prepreg 57 is, for example, wound around a portion such as the fishing line introducing port 6 of the base rod 1 for reinforcement or for reinforcement of an engaging portion of the rod body, and is woven on nylon fiber. It is also possible to use a prepreg impregnated with a synthetic resin.

Each of these prepregs is fired in a furnace. Thereby, each prepreg is integrated. Subsequently, the molding tape 57 is peeled off, the mandrel 50 is pulled out, both ends are trimmed and adjusted to an appropriate length, and the peripheral surface is polished and smoothed to manufacture the rod body 10.

After that, as described above, the synthetic resin is applied to the peripheral surface to form the synthetic resin layer 11, the peripheral surface is further smoothed, and the ceramic is physically vapor deposited to form the ceramic layer 1.
2 is provided and the clear layer 13 is provided to manufacture a rod body such as the middle rod 2.

The step of forming the ceramic layer 12 by physical vapor deposition will be described in detail. Among the physical vapor deposition, it is preferable to form by sputtering or ion plating, and the ceramic layer 12 having a high density and few pinholes is preferable. Can be obtained.

Further, it is particularly preferable to form by sputtering. That is, in the case of ion plating, since ceramic is attached to an electrode (filament) made of tungsten or the like, tungsten also slightly evaporates and adheres to the rod body 10, and the ceramic layer 1
The purity of 2 may be reduced. On the other hand, in the case of sputtering, there is an advantage that the ceramic layer 12 having a high purity can be easily obtained because the target ceramic can be directly attached.

Moreover, in the case of sputtering, there is an advantage that it is easy to form the ceramic layer 12 having a uniform thickness. For example, in order to obtain a good monochromatic color, it is necessary to make the thickness of the ceramic layer 12 uniform with high accuracy, but it is extremely difficult to control the thickness in the case of ion plating. On the other hand,
In the case of sputtering, it is possible to easily obtain a ceramic layer 12 having a uniform thickness, and thus a good monochromatic ceramic layer 12 can be obtained. In the case of chromium nitride (CrN, Cr ₂ N), for example, a dark silver or silver metal color is obtained, and for titanium nitride (TiN), a gold metal color (that is, golden color) is obtained.

Further, when the ceramic layer 12 is a metal nitride, a highly pure ceramic layer 12 can be obtained by sputtering, so that a monochromatic color is further improved and a uniform thickness can be formed, which is a favorable color development. Can be obtained. In particular, among metal nitrides, chromium nitride has good compatibility with sputtering, and the ceramic layer 12 made of highly pure chromium nitride can be uniformly adhered with high adhesion.

Here, the method of forming the ceramic layer 12 by sputtering will be described by taking the case of forming the ceramic layer 12 made of chromium nitride as an example. First, as a target, a chromium nitride (for example, Cr
N) is used, and in particular, a sintered body of chromium nitride is used. For example, a method of forming the ceramic layer 12 made of chromium nitride by reacting chromium with nitrogen gas as a reactive gas is conceivable, but the method makes it easy to form the ceramic layer 12 made of chromium nitride. is not. On the other hand, by using chromium nitride as the target, the ceramic layer 12 made of high-purity chromium nitride can be easily formed.
Moreover, if a sintered body is used, the manufacturing cost can be suppressed.

An example of the method for forming the ceramic layer 12 made of chromium nitride by sputtering will be further described. In the sputtering apparatus for that purpose, the target is attached to the outer wall of the vacuum container and the inside of the vacuum container is rod-shaped. The body 10 is configured to orbit while rotating on its own axis. That is, the rod main body 10 revolves around the front of the target and rotates. Using such a sputtering device, the vacuum vessel is evacuated to 7 × 10 ⁻⁵ Torr,
Nitrogen gas is introduced into the vacuum container up to 3 × 10 ⁻⁴ , and subsequently, argon gas is introduced up to 3 × 10 ⁻³ into the vacuum container. Then, DC power is applied to the rod main body 10 while rotating around the rod main body 10 as an object, and sputtering is performed using chromium nitride as a target. For example, DC power of 2.5 A × 600 V (= 1.5 KW) is applied for 20 minutes to form a chromium nitride film having a film thickness of 600 Å. Incidentally, nitrogen gas may not be introduced.

The rod bodies such as the intermediate rod 2 manufactured in this way are
The glass prepreg sheet layer 18 constitutes the outermost layer of the rod main body 10, and even if a large bending force or the like is applied to the rod body, cracks or the like do not easily occur, and even if cracks or the like occur, they will not spread further. On the other hand, the ceramic layer 12 made of metal nitride or metal oxide such as CrN, TiN, TiO ₂ is physically vapor-deposited on the synthetic resin layer 11, and the possibility that the ceramic layer 12 itself will be cracked is extremely small. For this reason, it is possible to sufficiently prevent the appearance of the rod body 10 from being damaged due to cracks and the like on its peripheral surface. Further, since the outermost layer of the rod body 10 is the glass prepreg sheet layer 18 and the polishing process is easy, it is easy to smooth the peripheral surface for physical vapor deposition of ceramics.

The outer surface layer 16 of the rod body 10 comprises a carbon fiber prepreg layer 17 and a glass fiber prepreg layer 18, and the carbon fibers are aligned in the circumferential direction on the inner circumference of the glass fiber prepreg layer 18. The prepreg layer 17 complements the rigidity in the circumferential direction, and the relatively thin glass fiber prepreg layer 18 can sufficiently maintain the bending strength of the rod body.

[Other Embodiments] The manufacturing method described in the above embodiment is merely an example, and as the method of forming the outer surface layer 16 of the rod body 10, for example, the following method can be exemplified. (A) As shown in FIG. 4, after forming a portion corresponding to the main body base layer 15 of the rod main body 10 with a predetermined prepreg, a carbon prepreg sheet 64 in which carbon fibers are aligned in the circumferential direction of the mandrel 50 is formed on the outer periphery thereof. Prepare and wind. Then, the glass prepreg sheet 65 is wound around the outer periphery thereof. The glass prepreg sheet 65 may be different from the above embodiment in that the glass is woven in a diagonal cross direction with respect to the mandrel 50. in this case,
By covering the seam at the winding end of the carbon prepreg sheets 64 aligned in the circumferential direction with the glass prepreg sheet 65, it is possible to prevent the surface layer from cracking. (B) As shown in FIG. 5, after forming a portion corresponding to the main body base layer 15 of the rod main body 10 with a predetermined prepreg, a carbon prepreg sheet 74 in which carbon fibers are aligned in the circumferential direction of the mandrel 50 is formed on the outer periphery thereof. Prepare and wind. Then, a method of sequentially winding a glass prepreg tape around its outer periphery in a spiral shape is also conceivable.

In forming the outer surface layer 16, the carbon fiber prepreg sheet is wound to form the carbon fiber prepreg layer 17 as in the above embodiment, and then the glass prepreg sheet is spirally wound to form the glass. There is also a method of forming the fiber prepreg layer 18. Further, the carbon fiber prepreg layer 17 may be formed from the carbon fiber prepreg tape, and the glass prepreg tape may be wound to form the glass fiber prepreg layer 18. (C) As the carbon prepreg sheet 74, it is also possible to use one in which carbon fibers are aligned in the axial direction of the mandrel 50.

Although the outermost layer of the rod body 10 is made of glass fiber prepreg in the above embodiment, the configuration of the rod body 10 can be variously changed.

For example, the rod body 10 of the middle rod 2 (rod body) shown in FIG. 6 includes a body base layer 15 and an outer surface layer 16 laminated on the outer peripheral surface of the body base layer 15 as in the configuration of FIG. However, it is different from the configuration of FIG. 2 in that the outer surface layer 16 does not have the glass fiber prepreg layer 18. That is, FIG.
The outer main body 16 of the rod main body 10 shown in (1) is composed of a carbon fiber prepreg layer. As described above, the layer structure of the rod body 10 can be variously changed, and the reinforcing fiber can also be appropriately changed. However, as the main configuration of the rod body 10, the reinforcing fibers are aligned in the circumferential direction in the innermost layer, and the reinforcing fibers are aligned in the axial direction of the rod body 10 in the intermediate layer, which is the main part of the rod body 10. In the outermost layer, the reinforcing fibers are aligned in the circumferential direction.

By the way, to describe the rod body shown in FIG. 6 in more detail, the rod body is provided with a plurality of ceramic layers on the outside of the rod body 10 with a transparent synthetic resin layer 11 interposed therebetween. Specifically, the ceramic layer 12 is composed of a lower ceramic layer 122 and an upper ceramic layer 121, the lower ceramic layer 122 is laminated on the outer peripheral surface of the synthetic resin layer 11, and the upper ceramic layer 121 is the lower ceramic layer. 122
Is laminated on the outer peripheral surface of the. The clear layer 13 is provided on the outer peripheral surface of the upper ceramic layer 121 in the same manner as described above.

The lower ceramic layer 122 and the upper ceramic layer 121 may be the same kind of ceramics, but are preferably different kinds of ceramics. For example, the lower ceramic layer 122 is made of metal nitride, and the upper ceramic layer 1
21 can be a metal oxide. CrN is used as the metal nitride and TiO ₂ is used as the metal oxide.

Thus, the upper ceramic layer 121 made of metal oxide and the lower ceramic layer 1 made of metal nitride.
In the case of stacking 22 with 22, it is of course possible to form both layers 121 and 122 together by sputtering, but it is also possible to deposit a metal nitride by sputtering and a metal oxide by ion plating. .

That is, when the lower ceramic layer 122 is a metal nitride, it is formed by sputtering, and when the upper ceramic layer 121 is a metal oxide, it is ion plated (in particular, reactive ion plating). Can be formed by. When formed in this way, the lower ceramic layer 122 having a uniform thickness is formed by sputtering, and good monochromatic coloring is first obtained. Further, by ion plating, the upper ceramic layer 121 having a complicatedly changed thickness can be formed, whereby the upper ceramic layer 121 that develops iridescent color by interference can be obtained. In this way, the two ceramic layers 121 and 122
Is formed, the upper ceramic layer 121 as a whole is formed.
Causes the rod itself to develop a rainbow color. When the lower ceramic layer 122 is chromium nitride (CrN) formed by sputtering and the upper ceramic layer 121 is TiO ₂ formed by ion plating, the entire rod body develops a rainbow color. It becomes a metallic color.
When a ceramic layer that develops iridescent color is formed by ion plating as described above, it is possible to form it directly on the rod body 10 or directly on the synthetic resin layer 11, For example, synthetic resin layer 1
It is preferable to form the lower ceramic layer 122 as described above on top of No. 1.

That is, the upper ceramic layer 1 that develops rainbow colors
By providing the lower ceramic layer 122 that develops a monochromatic color on the inside of 21, the rainbow color is further improved. When carbon fibers are included in the reinforcing fibers of the rod body 10, the rod body 10 becomes black due to the carbon fibers by being fired (heat-cured). Therefore, the black rod body 10
When only the ceramic layer that develops iridescent color is provided on the outside of the, the iridescent color may not always be good because the base is black. On the other hand, the upper ceramic layer 12
By providing the lower ceramic layer 122 on the inside of 1, the monochromatic lower ceramic layer 122 covers the black rod main body 10, so that the iridescent color of the upper ceramic layer 121 located on the outer side is prevented. It will be good. Even when the upper ceramic layer 121 has a single color, the color formation in the upper ceramic layer 121 becomes good by providing the lower ceramic layer 122 inside thereof.

In the example shown in FIG. 5, the ceramic layer 12 is composed of two upper and lower layers, but three or more layers may of course be used.

In the case of the rod body 10 in which carbon fiber is used at least in part as the reinforcing fiber, the synthetic resin layer 11
Besides being transparent, for example, a black synthetic resin layer 11 may be used. On the outer peripheral surface of the rod main body 10, when only the carbon fiber portion is particularly noticeable in black, by providing such a black synthetic resin layer 11, the coloring of the ceramic layer 12 provided on the outer side of the carbon fiber becomes It is preferable because there is no sparseness due to the influence of.

In addition, although the cylindrical rod 2 has been described as an example of the rod body, it may be a solid rod body, for example.
