PROBLEM TO BE SOLVED: To provide a method for production of a rod pipe for fishing rods, capable of easily polishing a peripheral surface in high accuracy.SOLUTION: A rod pipe 10 of a prescribed shape is formed by winding a prepreg around a metal core 2 followed by heat baking, and then grinding a peripheral surface 10a of the rod pipe 10 with the metal core, and the core is removed thereafter. The rod pipe is formed into a prescribed shape with an axially changing thickness by parallelly winding the sheet-like prepreg around the metal core 2 while having a constant thickness, and grinding the peripheral surface 10a of the rod pipe 10. In the end of the rod base side, the number of winds of the prepreg is larger by one than the number of winds corresponding to a designed thickness.COPYRIGHT: (C)2014,JPO&INPIT【課題】外周面を容易に高精度に研磨することができる釣竿用竿管の製造方法を提供する。【解決手段】芯金2にプリプレグを巻回して加熱焼成した後、芯金付きの状態で竿管10の外周面10aを研磨することにより所定形状の竿管10を形成し、その後脱芯する。また、芯金2にシート状のプリプレグを肉厚一定の並行巻きに巻回しておき、芯金付きの状態で竿管10の外周面10aを研磨することにより肉厚が軸線方向に変化した所定形状とする。また、竿元側の端部における設計上の肉厚に相当する巻き数よりも一回分多い巻き数でプリプレグを巻回しておく。【選択図】図3
