To provide a vehicle body pillar structure and a vehicle body structure which secure bond strength between a cylindrical body of a CFRP-made pillar and an outer layer member and are excellent in rigidity to collision load of lateral collision.SOLUTION: A vehicle body pillar structure comprises: a cylindrical body made of carbon fiber-reinforced resin; and an outer layer member made of carbon fiber-reinforced resin which is arranged at an outer periphery of the cylindrical body. The outer layer member includes a recessed groove part which is arranged at a face in a cylindrical body side and retreated in a direction apart from the cylindrical body to extend in an axial direction of the cylindrical body in which carbon fiber-reinforced resin is arranged in the recessed groove part including a continuous fiber wound around pin members installed at both sides in the axial direction of the recessed groove part and orientated along the axial direction of the cylindrical body.SELECTED DRAWING: Figure 3

    【課題】CFRP製のピラーの筒状体と外層部材との接合強度を担保するとともに、側面衝突の衝突荷重に対する剛性に優れた車体ピラー構造及び車体構造を提供する。【解決手段】炭素繊維強化樹脂からなる筒状体と、筒状体の外周に設けられた炭素繊維強化樹脂からなる外層部材と、を含む車体ピラー構造であって、外層部材は、筒状体側の面に、筒状体から離れる方向へ後退して筒状体の軸方向に沿って延びる凹溝部を有し、凹溝部内に、凹溝部の軸方向両側にそれぞれ設けられたピン部材に巻回されて筒状体の軸方向に沿って配向する連続繊維を含む繊維強化樹脂を配置した。【選択図】図3
