Description of the Related Art Generally, a rod body of a fishing rod is made of a high-strength fiber reinforced resin prepreg obtained by impregnating a high-strength fiber base material such as glass fiber or carbon fiber with a thermosetting resin such as an epoxy resin, and has a tapered rod-shaped mandrel. And calcined. Therefore, usually, the rod body of the fishing rod is formed in a tapered cylindrical shape. Various parts such as a reel sheet, a grip and a fishing line guide are mounted on a rod body of this type of fishing rod. When such a component is mounted, a built-up portion made of fiber reinforced resin may be formed on the rod body in order to match the outer diameter of the rod body to the inner diameter of the component.

れがある。In the conventional fishing rod having the built-up portion, the rigidity changes extremely at the boundary between the built-up portion and the rod body. In other words, the rigidity of the portion where the built-up portion is formed suddenly increases as compared with the rod body because of the increased thickness. When the rigidity changes suddenly in this way, when stress is repeatedly applied to the fishing rod, the fiber may peel off at the boundary where the rigidity changes rapidly. When the fibers are peeled off, the strength of the portion is weakened, and the rod body may be damaged.

Is provided in order to suppress a rapid change in rigidity due to a large change in thickness due to the build-up portion 18. Here, the tensile elastic modulus of the prepreg of the glass fiber reinforced resin used for the connecting portion 19 is 5 to 10 ton / mm 2, which is lower than the other portions (the rod body 17 and the build-up portion 18). The rigidity is lower than that of the build-up portion 18. The connecting portion 19 is formed so as to gradually become thinner as the distance from the end of the build-up portion 18 increases. For this reason, the rigidity at the connecting portion 19 gradually decreases.

なくなり、繊維が剥離しにくくなる。The built-up portion 18 and the connecting portion 19 having such a structure are manufactured as follows. As shown in FIG. 3, after the prepreg 30 serving as the rod body 17 is wound on a mandrel having a predetermined shape on which a release tape is wound, the padding portion 18 is provided on the outer peripheral surface of the mounting position of the fishing line guides 14 to 16. The prepreg 31 is wound. These prepregs 30, 31 are both made of carbon fiber reinforced resin. Then, as shown in FIG. 4, after the prepreg 31 is wound, a trapezoidal prepreg 32 serving as the connecting portion 19 is wound so as to partially overlap both ends of the prepreg 31. The prepreg 32 is a glass fiber reinforced resin formed such that the width on the side away from the build-up portion is slightly smaller than the width on the build-up portion so that the thickness gradually decreases from the end of the build-up portion 18 to the rod body 17. It is a trapezoidal sheet member made of. After winding the prepregs 30 to 32, a protective tape is wound around the outer peripheral surfaces of the prepregs 30 to 32 to obtain a rod material, and the rod material is fired. Thereafter, the release tape, the protective tape, and the like are peeled off, and the surfaces are ground to manufacture the rod bodies 11 to 13. Since the connecting portion 19 having low rigidity is formed at both ends of the built-up portion 18 formed in this manner, a sudden change in rigidity between the cladding portion 18 and the rod body 17 is reduced, and the fiber is hardly peeled. Become.

And an elastic member 26 non-rotatably mounted inside the cylindrical member 25. On a part of the outer peripheral surface of the cylindrical member 25, projections 25a for preventing the guide frame 20 from rotating with respect to the mounting portion 21 are formed at intervals in the axial direction. The projection 25a is provided in the recess 2 of the guide frame 20.

The stress is generated repeatedly. However, since the connecting portion 19 having low rigidity is provided adjacent to the built-up portion 18, a rapid change in rigidity is unlikely to occur at the end of the built-up portion 18, and the fiber is formed at the end of the built-up portion 18. Are difficult to peel off. On the other hand, when storing the swing rod, each of the fishing line guides 14 to 16 is moved from the padding portion 18 to the tip side.
Then, the third rod 13 is sequentially stored in the rod on the rod base side.
