These rod bodies are formed by firing a prepreg material in which a synthetic resin is impregnated with reinforcing fibers such as carbon fibers.

Each of the rods on the front side of the main rod 1 is connected in a so-called withdrawing form, and can be freely sequentially entered and exited from the front rod to the rod located on the root side. The outer peripheral surface of the root side end portion of the rod body on the front side can be fitted to the inner peripheral surface of the front side of the rod body adjacent to the root side, and can be fixed to each other. A fishing line stopper is arranged at the front end of the front rod located at the foremost side. The main pole 1 and the extension pole 2 located on the root side thereof, and the main pole 1 and the main upper pole 3 located on the front side, as described later, can be connected and fixed regardless of the extended state or the accommodated state. (For main rod 1) The main rod 1 as a whole is a cylindrical body that has been treated with a tapered rod that is reduced in diameter toward the front side. At the front end, the diameter of the side is reduced by a tapered rod with a larger slope than the other parts (the inner diameter is smaller than the other parts). The inner peripheral surface of the front end is a diameter in a certain axial direction range. No change face. The face with the same inclination as the diameter of the tapered shaft face from the father to the axial direction is the first mating female (Figure 2 and Figure 6). As described in detail later, the first fitting female part 1a is fitted into the main upper pole 3. As shown in Fig. 3, the end of the root of the main pole is the tail ring 邰 4 and tail bolt 邰 5 (see Figs. 4 and 5). The tail ring portion 4 is a cylindrical member made of metal (aluminum alloy). The inner peripheral surface of the root-side end portion is the first female thread portion forming a thread groove. 9- (7) (7) 200418369 points . The outer peripheral surface of the root-side end of the main pole 1 is partially cut off from the root-side end edge, and the front side of the tail ring portion 4 is mounted on the concave portion so that the tail ring portion 4 covers the recess. Into the part. At this time, the outer diameter of the tail ring portion 4 is set to conform to the outer diameter of the main shaft 1. The tail bolt portion 5 is a cylindrical member made of hard synthetic resin. The front side becomes a small-diameter insertion portion, and the root side end portion becomes a large-diameter head portion, and the outer diameter is in accordance with the outer diameter of the tail ring portion 4 described above. The insertion portion is a portion inserted from the root side of the main rod 1 into the inside thereof.

The second fitting female portion 5a 'of the tail bolt portion 5 is fitted into the front end portion of the extension rod 2 described later in the extended state (see Fig. 4). The outer peripheral surface on the root side of the insertion portion is a first male thread portion screwed to a first female thread portion of the tail ring portion 4 to form a thread groove. A concave hook groove 5b is formed on the inner peripheral surface (inner periphery of the head portion) of the root end portion of the tail bolt portion 5 in the axial direction. The tail bolt portion 5 is detachably attached to the main rod 1 via the tail ring portion 4 by screwing the first male screw portion to the first female screw portion of the tail ring portion 4. (For extension rod 2) As shown in FIG. 3, the extension rod 2 is composed of an insertion portion 6 inserted into the inside from the root side of the main rod 1, and a thick diameter of the root side connected to the insertion portion 6. Is composed of a handle member 7 of a tubular member. -10- (8) (8) 200418369 The insertion portion 6 is a cylindrical body having an outer diameter that can be inserted into the main rod 1. The insertion portion 6 is a member having a smaller diameter as it goes to the root side. The inner peripheral surface of the insertion portion 6 which is in contact with the slide ring 25 when the main upper rod 3 is accommodated is a structure having no change in diameter or a tapered rod shape with a very small inclination. The outer peripheral surface of the front end portion has a larger outer diameter in a certain range in the axial direction than the other portions, and here is the fitting male portion 6a. The outer diameter of this fitting male part 6a is an inverse tapered face of the second fitting female part 5a that fits the tail bolt part 5 of the above-mentioned main rod 1 (see Fig. 4). The insertion portion 6 includes a rubber case 8 disposed at the front end portion. The rubber case 8 is a cylindrical member formed of a conventional elastic rubber and hollowly penetrating in the axial direction. A part of the outer peripheral surface of the root side is cut out 'and is inserted into the front end portion of the insertion portion 6 and fixed with an adhesive. The inner diameter of the front side of the rubber case 8 is a tapered rod having a diameter enlarged toward the front end. A "crack" was formed in the axial direction from the front end. This rubber case 8 has a structure for smoothly guiding the main upper pole 3 into the insertion portion 6 when the main upper pole 3 connected to the front side of the main pole 1 is pulled out into the main pole 1. . The handle portion 7 is a tubular member having a larger diameter than the insertion portion 6 and a diameter matching the outer peripheral surface of the main shaft 1. It may be composed of a fiber-reinforced resin in the same manner as the main rod 1 or the insertion portion 6, or may be composed of another metal material. In a state where the insertion portion 6 is inserted from the front side, the handle portion 7 which can be detachably attached by a conventional method such as screwing attachment is connected to the root-side end portion of the insertion portion 6. The handle portion 7 may be in a state where the insertion portion 6 is fully inserted, or the insertion portion 6 is partially inserted into the front end portion of the handle portion -11-(9) (9) 200418369. Alternatively, the handle portion 7 may be connected in a detachable manner. A hook member 9 is fixed to the peripheral surface of the insertion portion 6 at the front end portion of the handle portion 7. The hook member 9 is formed of a synthetic resin, a light alloy, or the like. The outer diameter is the same as that of the handle portion 7 and the main rod 1 to the bottom bolt portion 5. The outer peripheral surface of the front side of the hook member 9 has a small diameter, and the small diameter peripheral surface has locking protrusions that protrude outward in the circumferential direction as a whole. The locking protrusion can be fitted into the hook groove 5 b of the tail bolt portion 5 (see FIG. 5). In this embodiment, the locking protrusion 9 of the hook member 9 and the hook groove 5 b of the tail bolt portion 5 are used to connect and fix the insertion portion 6 and the main rod 1. However, the following method may be adopted. For example, a thread groove is formed on a predetermined inner peripheral surface of the tail bolt portion 5 as a female screw portion, and a male screw member is disposed instead of the hook member 9 and the two are screwed together. In this case, a multi-head thread may be used for the screw thread. (For the main pole 3) The main pole 3 is a cylindrical body that is connected to the front side of the main pole 1 in a freely accessible manner (the so-called withdrawing form), and has a thin tapered rod as a whole (see Figure 1).
