Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a fishing rod connected by a plurality of rods, and in particular, a thin solid front end with a thinner front end. Conventional technology] Generally, a fishing rod used for fishing is to connect a plurality of rods that have been processed with a tapered tip to form a fishing rod. Each rod body is made of a prepreg made of carbon fiber, glass fiber, and other reinforced fibers in a regular arrangement and impregnated with a synthetic resin such as epoxy resin. In this type of fishing rod, a large-diameter main rod on the root side is Hollow tubular member. On the other hand, a small-diameter front-end thin rod located at the foremost side is made of a solid member for the purpose of reducing the diameter. Such a small-diameter front rod has sufficient bendability, and when a fish is caught on the fishing group, it can respond sensitively to the movement of its bait, can be flexed softly, and can smoothly perform fishing operations. Such a conventional thin rod is formed by winding a sheet-shaped prepreg material in which reinforcing fibers such as carbon fibers are aligned in the axial direction into a rod shape, and then firing the hardened material. Such reinforcing fibers aligned in the axial direction can increase the bending rigidity of the thinner rod with the smallest diameter, prevent damage, and exhibit a moderate degree of bending. [Problem to be Solved by the Invention] The forehead slim rod located at the foremost side of the fishing rod is a member that bends most in the axial direction when the fishing group catches a fish. However, at the same time, the rod closest to the rod of the fishing group is a thin rod. In particular, the front end of the thin rod on the front side will be used for fishing (please read the precautions on the back before filling this page). Printed by Consumer Cooperatives

Description of the Invention (2) The fish caught in the group rotates the fishing line in the circumferential direction, so it is also the easiest part to apply the torsional force in the circumferential direction. Therefore, it is also necessary to improve its torsional rigidity. In order to increase its torsional rigidity, it is necessary to prepreg the reinforcing fibers arranged in a circumferential direction. On the other hand, a thin rod in front of a small diameter also needs to maintain a large bending rigidity in the axial direction without The method ignores the prepregs in which the reinforcing fibers are aligned in the axial direction. Although there are also considerations for making the two coexist, it is not easy to increase the number of prepreg materials for front rods that require a smaller diameter. An object of the present invention is to provide a thin head with a high torsional rigidity and a sufficiently small diameter. [Means for solving the problem] The front slim rod of the first invention is a front slim rod located at the foremost side of a fishing rod composed of a plurality of rods that have been subjected to a tapered front end. Reinforced fibers are aligned in the axial direction and a solid root-side member composed of a prepreg impregnated with synthetic resin and a front side integrally connected to the root-side member are aligned in a circumferential direction or a crosswise direction. A solid front member made of a prepreg impregnated with synthetic resin. The front-end thin rod and the root-side portion of the front thin rod are root-side members made of a prepreg in which reinforcing fibers are aligned in the axial direction, and maintain sufficient bending rigidity in the axial direction. On the other hand, the front side of the fish that will catch the fish from the fishing group is subject to the largest torsional force in the circumferential direction.

Description of the invention (5) (Please read the precautions on the back before filling in this page) Thinner tapered cylindrical member. The root-side end portion of the rod body connected to the front side can be fitted and fixed to the inner peripheral surface of the front-side end portion in order (a so-called extraction form). On the peripheral surface of the main shaft 1, a winder seat 8 for detachably attaching a winder (not shown) is integrally arranged, and a tail bolt is attached to the end of the root side. On the other hand, the front thin rod 4 is a solid thin rod-shaped member made of carbon fiber reinforced resin, sloped glass fiber reinforced resin, or the like.

Although it is the same as the rod-side member 1 1 The prepreg material is formed from the prepreg material, but the reinforcing fibers of the prepreg material are aligned in a cross direction or a circumferential direction. The cross direction is deviated from the axial direction of the thin rod 4 i: 3 0 ~ 90 degrees The direction of the range. A hole recessed in the axial direction is formed at the end of the root side so that the above-mentioned protruding portion 1 1 a can be appropriately inserted. After inserting the protruding portion 1 1 a, the two are bonded with an adhesive. Fixed. In this case, the peripheral surface of the connecting part of the two members is smoothed by surface honing, and by surface coating, the appearance can be made no different from a rod. Adhesive to fix it, The auxiliary prepreg material can be wound around the connecting part of the two and then baked and integrated. It is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and the root side member 11 and the front side member 12 can be omitted. It is only necessary to make the arrangement direction of the reinforcing fibers different, and it is also possible to make the reinforcing fibers different. For example, the carbon fiber is used for the root-side member 11 and the glass fiber is used for the front-side member 12. Alternatively, the same material may be used. For example, it is also possible to use fibers with different elastic modulus of the root-side member 11 and the front-side member 12. The setting of the tensile elasticity is appropriate. The side member is composed of the root side member 11 and the front part is composed of the front side member 12.
