To provide a cylindrical body which is excellent in flexural rigidity and in which complete dividing is suppressed.SOLUTION: A cylindrical body 1 made of a fiber-reinforced resin, which is used as a structural material of a vehicle and in which corner parts 4 extending in an axial direction are formed on the outer peripheral surface, is constituted as a cylindrical laminated body comprising a plurality of textile layers 12 configured by impregnating a cloth made of reinforcing fibers with a resin and one-directional material layers 11, 13 configured by impregnating reinforcing fibers oriented in one direction with the resin. In the one-directional material layers 11, 13, the reinforcing fibers are oriented in a direction along an axial line of the cylindrical laminated body, and the one-directional material layers 11, 13 are laminated on the outer side of an outermost layer and on the inner side of an innermost layer of the textile layer 12.SELECTED DRAWING: Figure 1

    【課題】曲げ剛性に優れるとともに、完全に分断することが抑制された筒状体を提供する。【解決手段】車両の構造材として使用されるとともに、外周面に軸方向に延びる角部4が形成された繊維強化樹脂製の筒状体1であって、強化繊維からなる織物に樹脂が含浸されてなる複数層の織物層12と、一方向に配向された強化繊維に樹脂が含浸されてなる一方向材層11、13とを備える筒状積層体として構成され、前記一方向材層11、13では、前記筒状積層体の軸線に沿う方向に強化繊維が配向され、前記一方向材層11、13は、前記織物層12の最外層の外側及び最内層の内側に積層されている。【選択図】図1
