[Known technology] Among conventional fishing rods, a type of fishing rod called a fishing line that can be inserted through a fishing rod is a type of fishing line path that allows a fishing line from a winder to pass through the fishing rod. fishing rod. This fishing rod has an introduction port for introducing a fishing line into the body of the rod on the front side of the reel stand for attaching the thread reel. The fishing line from the thread reel is inserted into the body from this introduction port, sequentially guided to the front side, and led out from the front end side to the outside. Printed by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs On the other hand, as a method of connecting fishing rods formed by connecting plural rods, there is a so-called extraction type fishing rod. This extraction type connection method has a large diameter rod body and a small diameter rod body which can be accommodated in the large diameter rod body and connected to the front side thereof. The large diameter rod body has a fitting female portion on the inner periphery of the front end portion. The diameter rod body has a fitting male portion on the outer periphery of the root-side end portion. In addition, when fishing is required, each rod body is sequentially pulled out toward the front side, and the fitting male part and the fitting female part are fitted together to form a fishing rod. On the other hand, when it is to be stowed, the front-side rod is sequentially housed in the rod on the root side to be miniaturized. [Problems to be Solved by the Invention] A fishing rod can be inserted into such a fishing line, and there are great problems, and there is a problem that water can easily accumulate.

Therefore, recently, the inner surface of the rod has been coated with water-repellent paint, etc., and some measures have been implemented to make the fishing rod vibrate strongly. It is suggested that the water accumulated in the interior can be discharged to the front side in order. However, even when the fishing line can be inserted into the fishing rod, especially when plural rod bodies are connected together in the form of extraction, it is found that, at the connecting part of each rod body, the inner diameter of the rod body located on the front side and The difference in the diameter of the inner diameter on the root side can be an obstacle and prevent drainage. Therefore, it is desirable to develop a fishing rod that can smoothly remove the water accumulated in the rod body in consideration of the difference in diameter of the connecting portions between the rod bodies. In this regard, although it is also considered to form a drainage hole in the connecting part of the rods, etc., in a fishing rod that connects a plurality of rods in a drawn form, the connecting part of these rods is a root-side rod. The body is required to support the part of the pole located on the side, for example, to be able to ensure sufficient strength. Therefore, a structure such as a hole cannot be formed at will. The subject of the present invention is to provide a fishing line that can be inserted into a fishing rod, which will be printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, which will reduce the strength of the rod, and can easily exclude the water accumulated inside.

Description of the Invention (4) The notch groove formed in the fitting male part provides the function of a drainage groove. When the fishing line is plugged by vibrating the fishing line during throwing, the water accumulated in the large diameter rod will move forward. Once the water reaches the front side of the large-diameter rod body 1¾ of a minute, the water will pass through the cutout groove of the fitting male part of the small-diameter body and let the water be discharged to the outside of the small-diameter rod body. The fitting male part formed on the outer peripheral surface of the root-side end portion of this small-diameter rod body is composed of a fourth layer portion in which reinforcing fibers are arranged along the axial direction. Even if a notch groove is formed in the axial direction, The formation of the notch groove breaks the reinforcing fiber, and it is not easy to reduce its strength. In the vicinity of the coupling male part of the small-diameter annual body, as described below, the third layer part will not be damaged due to the cut groove, and the rod body can have sufficient breaking strength. Near the fitting male part of the small-diameter rod body, the diameter of the second layer portion is smaller toward the root portion side, and the diameter of the fourth layer portion is more toward the root portion side on the outer peripheral side of the third layer portion. In the larger form, various prepreg material layers are formed, and even if the notch groove is formed in the fitting male part, it is difficult for the notch groove to reach the third layer part. In short, even if the rod body with the tapered front end is stacked with various layers with a certain thickness, and the notch groove is formed in the axial direction at the root root side end, the notch groove processing It will be easily parallel to the axial direction of the rod body, so the depth of the cut groove on the root side will become deeper, and the cut groove will easily reach the third layer. In addition, the third layer portion is an important layer portion in which reinforcing fibers are arranged along the outer peripheral direction to maintain the breaking strength of the rod body, and damage to this portion significantly reduces the strength of the rod body.

Description of the Invention (5) In contrast, the small diameter rod body is made thinner toward the root side by making the second layer portion thinner, and made the fourth layer portion toward the rod. The thicker the root side, the opposite third layer portion will be arranged at a position far from the peripheral surface of the rod body, and it is difficult to damage the third layer portion even if a notch groove is formed. The small-diameter rod on the front side is supported by the large-diameter rod on the root side of the fitting male part, which can maintain this part to have sufficient breaking strength. In this type of fishing rod, the first layer portion and the third layer portion which is not damaged can be maintained so that the portion has sufficient damage strength.

Although each layer portion is shown separately in Fig. 3, these respective prepreg layers are baked and integrated. The specific stacking method for each prepreg material layer can be understood in the manufacturing method of the medium rod 3 described later. The thickness of the second layer portion 12 from the root-end-side end of the fourth layer portion 14 to the stack is thinner toward the root-side. On the other hand, the fourth layer portion 14 is thicker toward the root side. In addition, with this fourth layer portion 14, a fitting male portion 3a having a larger diameter than the other portions is formed in a certain range from the root-side end portion. As a result, as shown in FIG. 3, the middle rod 3 as a whole is subjected to a tapered rod treatment with a larger diameter toward the root side, and the thickness of the second layer portion 12 is reduced, and the fourth layer portion is reduced. It becomes thicker, so that the third layer portion facing toward the root side will be stacked deeper than the peripheral surface of the middle rod 3 (specifically, the peripheral surface of the fitting male portion 3 a). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and in this fitting male part 3 a (the part where the fourth layer part 14 is stacked), the cut groove 15 is formed to extend in the axial direction, and the cut groove The groove extends from the root end to the front side beyond the fitting range with the fitting male part (see FIG. 2). The notch groove 15 is formed by cutting the peripheral surface of the middle rod 3 and its deepest portion is substantially parallel to the axial direction of the middle rod 3. Due to the tapered rod of the middle rod 3, the notch groove moves toward the root side. The depth becomes deeper. "-Ll is that the notch grooves 15 are formed only in the range of the fourth layer portion 14 and do not reach the third layer portion 13. The notch grooves 15 themselves are at a plurality of positions at intervals in the circumferential direction. It is also possible to form a fishing line supporting protrusion 20 on the inner peripheral surface (innermost surface) of the first layer portion 11 of the middle pole 3. This fishing line supporting protrusion 20 is a Chinese paper standard ( CNS) A4 specification (210X297 mm) -10 · 523397 A7 B7 V. Description of the invention (8) (Please read the precautions on the back before filling this page) It is used to reduce the fishing line and rod passing through the inside of the pole 3. The structure of the contact area of the inner peripheral surface can be formed by arranging a strip-shaped prepreg material described later in a spiral shape. The structure of the fitting male part and the fitting female part is even between other rod bodies. The connecting portion is also formed in the same way. In this case, the number of the cut grooves 15 is smaller as the rod is closer to the front side. For example, the number of the cut grooves formed in the fitting male part of the front thin rod 4 is four. Left and right, when the main upper pole 2 is formed, about eight are set, and this difference can also be set Next, the manufacturing method of the medium rod 3 will be described. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, as shown in Figure 5 (a), a mandrel with a thinner tapered rod is prepared. (Core material) 1 0. A mold release agent is applied to the peripheral surface as needed. Then, a prepreg 3 1 and a release tape 3 2 for forming a protrusion are spirally wound around the mandrel. The prepreg 31 for forming protrusions is a strip-shaped material that is twisted with reinforcing fibers such as carbon fibers and is impregnated with epoxy resin. This is spirally wound around a mandrel 100. Then protrusions are formed. The gap between the prepreg 31 for the part is wound around the release tape 32. As described later, when the release tape 32 is peeled off, only the prepreg 31 for forming the protruding portion is left, and a fishing line supporting protrusion is formed. 20. Next, as shown in FIG. 5 (b), the first prepreg tape 4 1 is spirally wound around the outer periphery of each of the above materials without a gap. This first — prepreg tape 41 is along Reinforced fibers such as carbon fibers are arranged in the longitudinal direction of the tape and impregnated with synthetic resin Material. A suitable first 'pre-impregnated tape 4 1 forms the above-mentioned first layer portion 1 1. And the size of the first pre-rolled paper that is rolled up is in accordance with China National Standard (CNS) A4 (210X297 mm) -11-523397 A7 B7 V. Description of the invention (9) The outer circumference of the impregnated tape 4 1 is wound with the main prepreg material 4 2. (Please read the precautions on the back before filling this page} This main prepreg material 4 2 is Reinforced fibers such as carbon fibers are arranged along the axis of the mandrel 100 and are impregnated with a synthetic resin material. The main prepreg 42 is a tapered rod that fits the mandrel 100. The winding width is slightly trapezoidal as it goes toward the root side, and a large part is cut at the root side portion, and the winding width is processed to become smaller and smaller. In this way, by cutting most of the root side portion of the main prepreg material 4 2 (especially by making the winding width smaller toward the root side), the root side portion during winding Partially thinned (thinner toward the root side). This main prepreg material 4 2 forms a second layer portion 12. Then, as shown in Fig. 5 (c), the second prepreg tape 4 3 is spirally wound around the outer periphery of the main prepreg 42 without any gap. The second prepreg tape 43 is the same as the first prepreg tape 41 described above, and reinforcing fibers are arranged along the long axis direction of the tape. This second prepreg tape 43 forms the third layer portion 13 described above. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and, as shown in FIG. 5 (d), the auxiliary prepreg 4 4 is wound around the end of the root side where the second prepreg tape 4 3 has been wound (especially It is in a range where the above-mentioned main prepreg 4 3 is wound thinly). This auxiliary prepreg material 4 4 is a material in which reinforcing fibers such as carbon fibers are arranged in the axial direction in the same manner as the main prepreg material 4 2. The winding-up auxiliary prepreg material 4 4 is used to reinforce the thinning of the main prepreg material 4 2 so that the diameter of the entire body becomes larger toward the root side, and the thickness of the entire body becomes larger toward the root side. The auxiliary prepreg material 4 4 forms the fourth layer portion 14 to the fitting male portion 3 a.

Description of the invention (11) (Please read the precautions on the back before filling in this page), it is composed of the fourth layer part 14 with the reinforcing fibers arranged along the axis direction, even in the axis The formation of the notch grooves 15 in the direction does not break the reinforcing fibers due to the formation of the notch grooves 15 and it is not easy to reduce the strength thereof. This axial direction reinforcing fiber is a structure that contributes to the increase in bending rigidity. The formation of the notch groove 15 prevents the bending rigidity of the rod from being reduced. In the vicinity of this fitting male part 3 a, as shown below, as shown in FIG. 3, the diameter of the second layer part 12 decreases toward the root side, while the fourth layer part 14 relatively In the configuration where the outer peripheral side of the three-layer portion 13 is larger toward the root side, various prepreg layers are formed. Therefore, even if the notch groove 15 is formed in the fitting male portion 3 a (that is, the fourth layer portion 1 4), it is difficult for the notch groove 15 to reach the third layer portion 13 even if the notch groove is formed. It is also difficult for the groove 15 to break the third layer portion 13. The third layer portion 13 is a layer portion in which reinforcing fibers are arranged along the outer circumferential direction to ensure the breaking strength of the rod body. Further, the middle pole 3 is supported by the main upper pole 2 at the fitting male portion 3a, and sufficient breaking strength can be maintained in this portion. In such a fishing rod, the first layer portion 11 and the third layer portion 13 which are not damaged are used to maintain sufficient damage strength at that portion.
