PROBLEM TO BE SOLVED: To provide a wheel made of fiber-reinforced resin which has excellent strength and rigidity and can be improved in a degree of freedom of designing.SOLUTION: A wheel 1 has a plurality of spokes 3 extending radially from a hub fitting part 4 side at the center of the wheel toward a rim 2. The spokes 3 are formed of a hardened molding made of a UD material including a carbon fiber bundle and hardening resin which are orientated in one direction along an extending direction of the spokes 3 and a SMC material including short carbon fibers and a hardening resin. The UD material holds a first ring 14 to be arranged at the hub fitting part 4 and a second ring 15 to be arranged at the rim 2.SELECTED DRAWING: Figure 3
【課題】本発明は、強度と剛性とに優れ、設計自由度を向上させることができる繊維強化樹脂製のホイールを提供する。【解決手段】本発明は、ホイール中央のハブ取付部4側からリム2に向けて放射状に延在する複数のスポーク3を有するホイール1であって、前記スポーク3は、当該スポーク3の延在方向に沿って一方向に配向する炭素繊維束と硬化性樹脂とを含むUD材と、短炭素繊維と硬化性樹脂とを含むSMC材と、の硬化成形体で形成され、前記UD材は、前記ハブ取付部4に配置される第1リング14と前記リム2に配置される第2リング15とを抱持していることを特徴とする。【選択図】図3
