て強度低下する問題がある。However, the ones disclosed in Japanese Patent Publication No. 56-32882 and Japanese Utility Model Laid-Open No. 58-41164 described above include molding of thin-walled rod tube and reel seat body and grip portion. Since molding of the thick wall portion is performed at the same time, there is a drawback that the difference in wall thickness or uneven shape makes the resin flow during firing uneven, causing the rod body fibers to meander or eccentric, resulting in a decrease in strength. If the rod tube is first formed by heat treatment and then the reel seat body is attached or padded, the rod tube itself is deformed because it is heated again to the temperature at which the rod tube was processed. However, there is a problem that the wall thickness of the rod tube changes and the strength decreases.

易い。In the above-mentioned Japanese Utility Model Laid-Open No. 62-128760, since the aligned yarns are simply fixed with the paint, the paint hardly penetrates between the fibers. Therefore, the fiber cannot be securely held and fixed to the rod tube, and bubbles are generated inside, and pinholes are easily generated on the coated surface when dried.

に対する抵抗が増し、高強度な釣竿が提供可能となる。In each of the above embodiments, the fiber reinforced prepreg is used because it is necessary to firmly fix the equipment to the rod tube 12. However, in order to form a layer for simply covering and protecting a predetermined area, a low temperature curing resin is used. Figure 1 Example of using only prepreg
7 shows. In this example, in order to prevent the rod tube 12 from being crushed and damaged, reinforcing rings corresponding to bamboo knots are formed in various places in the length direction. First, in the same manner as in each of the above-mentioned embodiments, the basic overlay is formed into a multi-layer 42 by molding a fiber-reinforced prepreg impregnated with a low temperature curing resin, and the multi-layer 42 is formed.
In order to smoothly change the step of the surface of the, the multi-step layer 42 is covered with a prepreg made of only low temperature curing resin without fibers,
The same low temperature curing treatment as in each of the above-described examples is performed to form the coating protective layer 44. As a result, resistance to crushing deformation of the rod tube 12 increases, and a high-strength fishing rod can be provided.
