[Prior Art] The bamboo raft is softly bent, and the response to the bending (recovering the original state) is stable, so the fishing feeling is good, and various bamboo rafts are manufactured and sold. However, bamboo stalks are used for direct processing of natural bamboos, and processing such as "winding and coating processing", but their performance is deeply affected by the degree of bamboo growth or processing methods. Since the quality of each of the defects (easiness of bending) and the like are varied, there is a problem that it is not easy to manufacture a product having uniform quality. Therefore, in recent years, the replacement of bamboo rafts has become a mainstream of fishing rods in which carbon fibers or glass fibers are formed as reinforcing fibers and fiber-reinforced resins. Because the fishing rod formed by such a fiber-reinforced resin is not directly used as a natural product such as bamboo raft, it is uniform in quality, and has the advantages of being lightweight and strong in strength compared with bamboo stalk. In recent years, it has been used in almost all Fishing. However, a fishing rod composed of a fiber-reinforced resin using carbon fiber or glass fiber as a reinforcing fiber may be bent by an increase in external force such as fish pull or fish letter, but it is easy to recover immediately because the external force is reduced or disappeared. Since it is in the original state, it is too sensitive to the return of the bending. (2) 1272058 As a result, there is a problem that the reaction is mechanical and the fishing feeling is lacking. [Explanation] (Problems to be solved by the present invention) Therefore, An object of the invention is to provide a fishing rod which can produce a uniform quality, such as a bamboo pole, and which is gentle to the recovery of the bending, and which has an excellent fishing feeling. (Means for Solving the Problem) In the fishing rod which is composed of the fiber-reinforced resin which is a reinforced fiber, the inventors of the present invention use a fiber having a predetermined thickness from the bamboo. In the case where the glass fiber or the carbon fiber is also used in the same manner, it is found that the recovery operation for the bending is gentle, and the present invention has been completed. In other words, in the fishing rod of the present invention, the fishing rod of the present invention is characterized in that the reinforcing fiber has a diameter of 0.01 to 0.5 mm. Loose bamboo fiber. A bamboo fiber having a diameter of 0.01 to 5.5 mm is usually a flexible fiber in a predetermined range. By using the fiber as a reinforcing fiber, a predetermined amount is used, and a fishing rod (bamboo) using only bamboo itself is used. In comparison, it is possible to reduce the difference in quality due to the situation of each defect. Moreover, although the effect is not clear, after the reinforcing fiber is used, the external force is reduced or removed by bending of the external force, and (3) 1272058 will temporarily exhibit a slight plasticity, and use carbon fiber. In comparison with the case, the time required for recovery in the original state is longer, the recovery for bending is gentler, and the fishing feel is excellent. Further, in the present invention, the diameter of the bamboo fiber means the distance (i.e., the maximum diameter) at the farthest point in the cross section perpendicular to the axial direction, and this is measured from the cross-sectional photograph of the microscope. In the present invention, the bamboo fiber is directed in the axial direction of the manifold. By allowing this structure to function, the effect of easing the recovery of the bending can be achieved, and the fear of complete plastic deformation due to bending can be reduced. Further, the bamboo fiber is preferably subjected to heat treatment. By using the heat-treated bamboo fiber as a reinforcing fiber, it is possible to form a fishing rod which is highly elastic and which is less likely to cause complete plastic deformation. Here, the term "heating processing" refers to a process in which the water and the oil are evaporated without being heated by carbonization in the state of the bamboo before the fiber is taken out or in the state of the fiber to be extracted. This heating process is usually carried out at a temperature of 1 500 to 800 ° C for a few seconds (specifically, about 1 to 10 seconds). In the heat processing, in the case of producing a crucible tube (e.g., a carbon rod) composed of a fiber-reinforced resin having carbon fibers as a reinforcing fiber, a calcining furnace may be used in order to cure the resin by heating. Further, in the present invention, the reinforcing fibers are more preferably carbon fibers or glass fibers. -8- (4) 1272058 When only bamboo fiber is used, when a large external force acts, large bending occurs, and there is a possibility that plasticity deformation that can never be restored to the original state may occur, but further, because of strengthening Fibers with fiberglass or fiberglass can reduce the anxiety of this plastic deformation. The carbon fiber or the glass fiber is preferably oriented in the circumferential direction. - According to this configuration, even if the cross section of the manifold is changed from a circular shape to an elliptical shape due to large bending or the like, the carbon fiber or the glass fiber directed in the circumferential direction is reinforced, and it becomes difficult to break and is not easily broken. EMBODIMENT OF THE INVENTION The fishing rod of the present invention will be described with reference to the drawings. In the fishing rod of the present embodiment, for example, as shown in Fig. 1, a plurality of manifolds 4 are connected in a segment or a pull-out manner (see Fig. 1 (a)). The manifold 4 is formed of a fiber-reinforced resin and has a tubular structure of a layer structure of the innermost layer A, the intermediate layer B, and the outermost layer C from the inner side toward the outer side (refer to Fig. 1(B)). Φ Further, the intermediate layer B includes an outer intermediate layer B 1 disposed on the outer side and an inner intermediate layer B 2 disposed on the inner side. In the innermost layer A, carbon fibers (elasticity: 15,000 to 60000 kgf/mm2, usually, elastic modulus 24,000 to 40000 kgf/mm2, and the following carbon fibers are the same) as the reinforcing fibers are directed in the circumferential direction S1. In the inner intermediate layer B2, the carbon fibers as the reinforcing fibers are directed in the axial direction S 2 . In the aforementioned outer intermediate layer B 1 , the reinforcing fiber is composed of a fiber bundle of -9 - (5) 1272058 phloem located in the bamboo and a bundle of the fiber bundle of 0.01 to 0.5 mm in diameter. Bamboo fiber 5. For the bamboo fiber 5, for example, a bamboo fiber (bamboo fiber) of raw material fibers of "Bamboo Allat" (trade name) manufactured by Nomura Industries Co., Ltd. can be used. This bamboo fiber 5 is pulled in one direction and directed in the axial direction S2 of the manifold 4. In the innermost layer A, the carbon fibers as the reinforcing fibers are directed in the circumferential direction S1. Next, in the case of manufacturing the manifold 4, referring to the description of Fig. 2, first, as shown in Fig. 2 (a), an epoxy resin or the like is impregnated into a sheet in which only the carbon fibers 1 are aligned in one direction. The prepreg A (hereinafter sometimes referred to as "the innermost prepreg") in the form of a matrix resin sheet is wound around the core shaft 3 in the circumferential direction S 1 . Further, the resin impregnation amount of the innermost prepreg is usually set to 2 to 40% by weight. The innermost layer A is constituted by the innermost prepreg a. In the same manner, a matrix resin sheet-like prepreg B2 (hereinafter referred to as "inner intermediate layer prepreg") in which a matrix resin or the like is impregnated into a sheet in which only the carbon fibers i are aligned in one direction is used to make carbon fibers. 1 is wound around the outer circumference of the innermost prepreg A in the circumferential direction S2. The resin impregnation amount of the inner intermediate layer prepreg B2 is usually set to 2 〇 to 5 〇 by weight. The inner intermediate layer B 2 is formed by the inner intermediate layer prepreg B 2 . -10- (6) 1272058 In the same manner, the bamboo fiber 5 is impregnated with a matrix resin sheet-like prepreg B 1 which is combed in a fiber state and has only the carbon fibers 1 aligned in one direction (hereinafter It is called "bamboo fiber prepreg", and the bamboo fiber is wound around the outer circumference of the inner middle layer prepreg B2 in the circumferential direction S2. The resin impregnation amount of the bamboo fiber prepreg B 1 is usually set to 20 to 50% by weight. The intermediate layer B 1 is constituted by the bamboo fiber prepreg B1. Next, as shown in Fig. 2(B), the strip-shaped outermost prepreg C in which the carbon fibers 1 are aligned in the longitudinal direction is wound so that the carbon fibers 1 are directed in the circumferential direction S1. The resin impregnation amount of the outermost prepreg C is usually set to 20 to 50% by weight. The outermost layer C is formed by the outermost prepreg C. Thus, the outer circumference of the plurality of prepregs A, B 2, B 1 and C is wound, and the forming belt (not shown) is appropriately pressure-adjusted. After being taken up, it is heated and calcined by a predetermined temperature. After heating and calcining, the core shaft 3 is removed, the forming belt is peeled off, and further, by cutting into a predetermined length, a tubular tube 4 can be obtained. Next, an example of a method of extracting the bamboo fiber 5 from bamboo will be described. . First, the leaves are removed from the bamboo of the collection, directly (not cut) or cut into a predetermined length. After drying by sunlight, heat processing is performed. The heating process can be carried out, for example, by heating the bamboo by fire, and heating the bamboo by -11 - (7) 1272058 1 50 0 to 80 ° C for several seconds. By this heat processing, the moisture and oil contained in the bamboo are evaporated, and the crucible is in a state of being adjacent to carbonization. Next, the pectin which binds the fiber bundles to each other is dissolved and removed from the bamboo which is dried by the heat processing. As a method of relaxing the pectin, for example, a fermentation method or a drug method which is used when extracting from the mahjong fiber can be employed. The pharmaceutical method can be exemplified by immersing bamboo in an aqueous solution of caustic soda and heating it. Next, after drying, it is crushed by a calendering apparatus. The xylem of the inner peripheral side of the bamboo is broken and broken by breaking. As the calendering apparatus, a conventionally known one can be used, for example, a calender type calendering apparatus, an imprinting type calendering apparatus, or the like. In the case of a rolling device of a roller type, the bamboo fiber 5 is passed along the growth direction of the bamboo fiber 5, and the bamboo is split in a bundle along the growth direction. The bamboo is loosened by a fiber recycling machine. The bamboo fiber 5 of a desired diameter composed of a bundle of fiber bundles or fiber bundles of the phloem portion is formed by adjusting the size, number, rotation speed, and the like of the teeth of the fiber regenerating machine. As the fiber regenerating machine, for example, an IM-3 4 type fiber reclaimer manufactured by Quannan Needle can be used. * If the loose fiber is not sufficient, use a turbine honing or the like as needed, and loosen the fiber finer, for example, the fiber bundle of the phloem or the bundle of the fiber bundle has a diameter of 0.01 to 0.5 mm. Bamboo fiber 5. Further, in the present embodiment, a prepreg in which the bamboo fibers 5 are combed in the fiber state -12-(8) 1272058 and aligned in one direction is used, but for example, a cotton spinning method or the like may be used. The prepreg in which the spun yarn of the bamboo fiber 5 is spun in one direction is aligned. Further, in the woven fabric of the spun yarn, the use of a prepreg impregnated with a matrix resin is also within the intended scope of the present invention. In the present embodiment, the manifold 4 is a four-layer structure in which the intermediate layer B between the outermost layer C and the innermost layer A is two layers. However, in the present invention, the manifold 4 is The structure of several layers may be used, for example, a three-layer structure or five or more layers may be used. Further, in the present embodiment, the bamboo fiber 5 is only used as the reinforcing fiber of the intermediate layer B. However, it is also within the intention of the present invention to use the reinforcing fiber as the outermost layer C, and the reinforcing as the outermost layer C is used. Fibers are also within the intended scope of the invention. Further, the fishing rods in which the plurality of manifolds 4 are connected in a segmented or withdrawable manner are reinforced fibers of the connecting portions 4a and 4a (or only the connecting portions 4a and 4a) of the manifolds 4 that are fitted to each other. Bamboo fiber 5 may also be contained (refer to Fig. 1). In such a fishing rod, not only the fishing performance is excellent as described above, but also the bamboo fiber is softer than the carbon fiber, so that the wear of the connecting portions 4a and 4a is reduced, and the fear of mutual injury can be reduced. Further, by appropriately raising the bamboo fibers to form a cross section (a profiled cross section) having a large degree of non-circularity, the contact area between the joint portions 4a and 4a can be reduced. In the segmented fishing rod, there is a case where the joint portion 4a on the male side is coated. In this case, the reinforcing fibers of the connecting portion 4a on the female side are not easily damaged by using the bamboo-13-1272058 Ο fiber. The coating film on the male side. Further, when the coating as described above is carried out, a click sound occurs at the time of joining, but the sound is reduced by the bamboo fiber. (Effects of the Invention) As described above, the fishing rod of the present invention has less quality difference due to the condition of each of the rods than the bamboo rods directly used, and the reinforcing fibers are made of bamboo fibers. After the external force is bent, the external force is reduced or removed, and the plasticity is slightly exhibited at one time. Compared with the case of using carbon fiber or the like, the recovery time in the original state is longer, and the recovery of the bending is gentler. And has an excellent fishing sense.
