PROBLEM TO BE SOLVED: To provide a method of manufacturing a bar-like component, which is capable of improving strength of the bar-like component while reducing a manufacturing cost of the bar-like component in the case of constituting the bar-like component by connecting a pipe made of carbon fiber-reinforced resin with a metal component.SOLUTION: A bar-like component 22 includes a pipe 10 and metal components 17, 18. A method of manufacturing the bar-like component 22 includes: a process of winding a carbon fiber 25 and a thermoplastic resin fiber 26 round a core material including a metal ring 16 which has an outer peripheral surface 16A to which surface roughening work is applied; a process of melting the thermoplastic resin fiber 26 by heating the thermoplastic resin fiber 26 wound round the outer peripheral surface of the core material while pressurizing the fiber 26; a process of forming the pipe 10 in which end parts 10A, 10B are externally fitted to the outer peripheral surface 16A, by cooling thermoplastic resin which is melted and impregnated into the carbon fiber 25; and a process of screw-fastening the metal components 17, 18 and the metal ring 16.

    【課題】炭素繊維強化樹脂製のパイプと金属部品とを連結することでバー状部品を構成する場合において、バー状部品の製造コストの低減を図りつつ、強度を向上させることができるバー状部品の製造方法を提供すること。【解決手段】バー状部品22は、パイプ10と、金属部品17、18とを含む。バー状部品22の製造方法は、粗面加工が施された外周面16Aを有する金属円環16を含む芯材に炭素繊維25および熱可塑性樹脂繊維26を巻き付ける工程と、芯材の外周面に巻き付けられた熱可塑性樹脂繊維26を加圧しながら加熱することで熱可塑性樹脂繊維26を溶融させる工程と、溶融して炭素繊維25に含浸した熱可塑性樹脂を冷却することで、外周面16Aに対して端部10A、10Bが外嵌固定されたパイプ10を形成する工程と、金属部品17、18と金属円環16とをねじ締結させる工程とを含む。【選択図】図8
