Description of the Related Art Conventionally, a fishing rod consisting of a rod tube manufactured by winding a prepreg impregnated with synthetic resin in high-strength fiber around a core metal has a taper portion on the outer circumference in the longitudinal direction of the fishing rod.
As shown in Japanese Patent Laid-Open No. 2-113931 and FIG. 8, the core metal 4 of FIG.
While forming the taper portion on the prepreg 7, the prepreg 7 was cut along the straight line of the cutting line a inclined in the longitudinal direction and the other cutting lines b and c so as to correspond to the taper portion.

る。As described above, when the cutting line a inclined in the longitudinal direction and the other cutting lines b and c are cut by straight lines so that the prepreg 7 corresponds to the taper portion, the cutting direction is sharp. There are crossing change points α and β between the cutting lines that change to. When the intersection change points α and β are formed, the fibers on the side of the cutting lines a and c at the intersection change points α and β become the cut end portions which are abruptly changed. Among the crossing change points α and β of the cutting lines at the time of cutting, the crossing change point α, which is particularly inside, has a drawback of cutting more into the cutting line a side or other cutting line b side and both sides like a broken line, The more cuts, the shorter the fibers that should be long.

中が起こって破損し易くなる。Next, in the processing step of winding the prepreg around the core metal 4, the following defects occur at the crossing change points α and β between the cutting line a inclined in the longitudinal direction and the other cutting lines b and c. Was there. After winding the prepreg, tape outside the intersection change point.
When pinging is performed, the tension of the tightening tape causes the fiber 2 end portion at the intersection change point α to change abruptly in the cutting direction as shown in FIG. 9, resulting in misalignment, meandering, or wrinkling. To do. For this reason, a portion where fibers are overlapped with each other at a crossing change point of the wound prepreg and a portion where no fiber is formed are formed, and the portion where no fiber is formed in the rod tube after molding has low strength and is easily damaged.
Since the cutting direction changes abruptly at the intersection change point, the impregnated resin becomes coarse and dense at the time of heat curing, and steps 8 are formed as shown in FIG. When using a fishing rod,
The bending balance at the intersection change point becomes unbalanced and bending occurs. When a combined force of bending force and twisting force acts on the intersection change point, stress concentration occurs on the fiber-free portion or the step portion, and the fiber is easily damaged.
