[Operational effect] • In other words, when the intermediate stern reinforcement structure is disposed on the inner side of the outer layer portion, the orientation of the intermediate stern reinforcement structure is transmitted with respect to the shear force propagating from the tail end portion of the outer layer portion. The reinforcing fibers aligned in the axial direction exert a resistance, so that the peeling of the reinforcing fibers or the fatigue of the resin can be prevented. According to a fourth aspect of the invention, the inner side tail portion reinforcing structure is disposed inside the inner end portion of the inner layer portion, and the inner side tail portion reinforcing structure is overlapped; the length along the axial direction is shorter than the main structure. And the prepreg -9 - (7) 1343783 material arranged in a line along the first inclination angle with respect to the 竿 axis of the reinforcing fiber group, and the length along the axial direction is shorter than the above main structure, and the reinforcing fiber group is The prepreg is arranged in a symmetrical state with respect to the above-mentioned 竿 axis and the reinforcing fiber group of the prepreg, and the effect is as follows. [Operational effect] At the end of the sacral end of the sacral body, 'the inner side of the inner layer is also φ, and the inner stern end is reinforced.

The slit strip 3, which covers the entire length of the mandrel 4, is spirally wound around the mandrel 4, which is wound around the second main structure 2B, to form the outer layer portion Ac. The third dovetail reinforcing structure 6 which is a reinforcing structure of the dovetail portion will be described. The third stern-reinforcing structure 6 is a pair of reinforcing fibers c composed of carbon fibers arranged in a line at a third inclination angle of 0 3 with respect to the 竿 axis X, and is impregnated with a thermosetting resin such as an epoxy resin. The formed φ prepreg and the reinforcing fiber c which are arranged in a symmetrical state with respect to the 竿 axis X and the reinforcing fiber c of the prepreg are formed by impregnating a thermosetting resin such as an epoxy resin. The material is pre-impregnated and cut to a length such that its length corresponds to the axial direction of the dovetail end of the carcass. As described above, the body A is configured by winding each structure in the mandrel 4 in order. On the other hand, the inclination angle 0 of the reinforcing fibers of each reinforcing structure can be set in the range of Γ 9 9 (Γ, and is preferably set to be in the range of 45 〜 8 (Γ Φ), and the first inclination can also be set. The angles 0 to 4 are set to the same angle, and the inclination angles may be set to different angles. [Second embodiment] A method of manufacturing the body Α will be described. In one embodiment, a structure in which the first and second main structures 2A and 2B are overlapped and wound as a second level is shown. In the second embodiment, only the first main portion as the intermediate layer portion Ab may be wound. The structure 2A is the same as the other inner layer portion Aa, the outer layer portion Ac, the opening portion reinforcing structure 5, and the-13-1343783 tail-end reinforcing structure 6. That is, in the second embodiment, There is a method in which only the first main structure 2A as the intermediate layer portion Ab is implemented. Thereby, although the resistance of the intermediate layer portion Ab with respect to the tensile force is lowered, the weight reduction of the carcass can be achieved instead. Case, with the 竿 shown in the first embodiment Compared with the corpuscle which can be used for small fish, the third embodiment is described with respect to the manufacturing method of the corpus callum A. As shown in Fig. 3, as the first layer, it is in the core. The shaft 4 is wound around the opening reinforcing structure 5' and the first dovetail reinforcing structure 7, and the reinforcing structure 5 around the opening portion and the first dovetail reinforcing structure 7 wound around the mandrel 4 are The first slit strip is wound as the inner layer portion Aa. As the second layer, the first strip strip 1 that has been wound is overlapped and wound: as the first main layer of the intermediate layer portion Ab Structure 2A and second main structure 2B. From the second main structure 2B, 'wrap the second dovetail reinforcement structure 8» and as the third level 'from the second main structure 2B and the second dovetail reinforcement structure 8, Winding the second slit strip 3 as the outer layer portion, and winding the third tail reinforcing structure 6 from the second strip strip 3. That is, in the third embodiment, with the first embodiment The difference is that 'as the reinforcing structure of the tail, the first tail is reinforcing the structure 7 Placed on the inner side of the first strip-shaped belt rafter, and the second shin-reinforcing structure 8 is disposed outside the second main structure 2B. -14- (12) 1343783 Thereby, the stern-reinforcing structure is disposed in each layer Therefore, it is not only the outer side surface that is in contact with the target side crimping surface, but the reinforcing structure can be provided in each layer portion, and the resistance against the shearing force can be improved, and the deformation of the carcass can be effectively prevented. As the body to which the third embodiment is applied, compared with the structure of the second embodiment, it is suitable for catching a larger type of fish, and even if a large load is applied, the three dovetail reinforcing structures at the joint portion B are opposed to The shearing force can also exert a resistance, and it is possible to suppress the φ deformation or the like at the joint portion B. In the third embodiment, the second tail-reinforcing structure 8 is applied to the second main structure 2B. The position at which the second dovetail reinforcing structure 8 is provided may be between the first main structure 2A and the second main structure 2B, or may be inside the first main structure 2A, or may be provided in the above-mentioned One master 2A, the inner structure, between the first main structure 2A and 2B a second primary structure, and a second position outside the three primary structure 2B. [Other Embodiments] (1) As the structure of the third dovetail reinforcing structure 6, the following structure may be employed. In other words, as the third dovetail reinforcing structure 6, the prepreg formed by inclining the reinforcing fiber c group to the crucible axis X is used so as to overlap each other so that the reinforcing fibers c cross each other. The body 6 A 〇 is relatively in the present embodiment, and after the above-mentioned overlapping body 6A is wound, •15-(13) 134.3783', as shown in Fig. 4, is a projection in which a plurality of resins are provided from the overlapping body 6A. The construction of 9. The method of forming the protrusions 9 of the resin is not shown, but the surface of the superposed body 6A of the resin-forming protrusions 9 is covered with a mask member that forms a plurality of through holes, and the mask is used from the mask by using a spraying method. When the coating material for the projection is sprayed on the member, the coating material is adhered to the surface of the superposed body 6A through the through hole of the mask member to form the projection portion 9. The portion where the protrusion portion 9 is formed is a state in which the anterior tibial body is extracted from the appendix® side carcass, and is formed on the inner side which is not protruded more than the crotch side of the caudal side carcass, and does not lose the appearance. . By forming the protrusions 9, the surface 'end of the end portion of the crotch portion of the front side of the crotch body does not fully abut against the inner peripheral surface of the crotch tip end portion of the crotch side body by the protrusions 9 at each other A gap is formed between them to retain moisture in the gap portion. When the surface of the end portion of the crotch of the anterior tibial body is in close contact with the inner peripheral surface of the anterior end portion of the crotch body of the appendix, moisture will enter the abutment portion ® 'and because of the intervening moisture, It will produce a close-knit phenomenon that makes the adhesion stronger. Due to this close-fitting phenomenon, the extracted anterior iliac crest body cannot be returned to the crotch side iliac crest, and since the protrusion 9' is formed here, only the protrusion 9 abuts against the appendix side 竿The inner peripheral surface of the tip end portion of the body does not become in a state of full adhesion, and the water is also interposed between the adjacent protrusions 9'. The surface of the end portion of the front side of the iliac crest and the dovetail body The closeness of the inner peripheral surface of the front end portion of the crucible is not improved. Instead of the third dovetail reinforcing structure 6, the projecting portion 9 may be formed separately. -16· 8 (14) 1343783 (2) As the structure of the third dovetail reinforcing structure 6, the following structure may be employed. As the third dovetail reinforcing structure 6, a prepreg formed by inclining the reinforcing fiber c group to the crucible axis X is used, and the superposed body 6A in a state in which the reinforcing fibers c are mutually intersected is superposed on each other. It is also possible to overlap the auxiliary structure 6B as described below with the overlapping body 6A. In other words, as shown in Fig. 5 (δ), the auxiliary structure 6B is a prepreg formed by impregnating a reinforcing fiber c such as carbon fiber in a circumferential direction and then impregnating a thermosetting resin such as an epoxy resin. Material 6 a, a highly flexible fiber c such as nylon or polyester is cross-assembled, and a prepreg 6b formed by impregnating a thermosetting resin such as an epoxy resin is superposed so that the carbon fibers are aligned on the circumference. The prepreg 6a in the direction is wound on the inner side of the superposed body 6A. As shown in Fig. 6, the length of the auxiliary structure 6B in the axial direction is shorter than that of the overlapping body 6A, and the auxiliary structure 6B is wound around the front side of the overlapping body 6A. Here, the arrangement state of the overlapping body 6A and the auxiliary structure 6B will be described. The overlapping body 6A located on the inner side is disposed to correspond to the length of the joint portion B. On the other hand, the auxiliary structure 6B is shorter than the overlapping body 6A and is disposed at a position close to the front side of the ankle. Even if the overlapping body 6A is disposed to correspond to the length of the joint portion B, the length of the joint portion B is shorter than that of the joint portion B, so when the front side body 1 is pulled out from the tail side body 2, the overlap body 6A The front end of the crucible with the auxiliary structure 6B does not protrude from the front end of the crucible body 2, and the appearance can be improved. -17- 1343783 Further, since the overlapping body 6A is provided at the shoulder portion on the front side of the joint portion B, the strength of the portion can be increased, and the front side end of the joint portion B of the front side body 1 can be avoided. The damage of the carcass such as "breaking at the boundary" generated in the vicinity. In the case where the prepreg material 6b on the surface side of the body of the auxiliary structure 6B is described in detail, as shown in Fig. 5 (α), in the prepreg 6b, the fiber c having high flexibility is made into a staggered web. A shape in which the fibers c are arranged in a tortoise shape. As shown in Fig. 5 (β), the resin impregnated into the fiber c is honed, and the fiber is exposed on the surface to form a tortoise-like recess. As the fiber having high flexibility as used herein, a resin fiber such as nylon or polyester is used. Then, the prepreg 6b is placed on the surface of the joint portion, and even if the prepreg that forms the joint portion B on the target side is in a pressure-bonded state, there is a tortoise-like recess. Therefore, even if moisture is interposed, moisture is only The tortoise-like recess is accumulated, and the crimping state is not strengthened, and the adhesion of the joint can be alleviated. (3) The structure of the present invention can be applied not only to a fishing rod, a squid, or the like, but also to a parallel type or a catching fishing rod.
