PROBLEM TO BE SOLVED: To provide a vehicle body structure of an automobile side part which can be reinforced in a box shape even if a hinge reinforcement is not thick in thickness, and prevents an increase of the weight of a front pillar and the enlargement of a shape by efficiently performing load transmission and distribution by collecting a collision load at a small overlap collision which is inputted from a vehicle body side part to a front of a door load transmission member.SOLUTION: An inward-opening U-shaped hinge reinforcement 70 in a vehicle width direction at a rear facing part of an apron reinforcement 18 is arranged in a hinge pillar 4, and in the hinge reinforcement 70, a rear-side flange in which an inside flange 76 between an upper wall 71 and a lower wall 72 is extended while linearly inclining to the outside of a rear part from a connecting region of a cowl panel 50 or a dash reinforcement 53, and which is bent to at least either of the upper wall 71 and the lower wall 72, and a rear-side flange 73F which is bent to a sidewall 73 to which a door hinge 6 is fixed are superimposed on each other in a position in which the rear-side flanges oppose a door load transmission member 84 which is located in a door 8.SELECTED DRAWING: Figure 5
【課題】ヒンジレインが分厚くなくとも、箱形状に補強でき、車体側部から入力されるスモールオーバラップ衝突時の衝突荷重を、ドア荷重伝達部材前方に集めて、効率的に荷重伝達、分散を図り、フロントピラーの重量や形状の拡大を防止する自動車の側部車体構造を提供する。【解決手段】ヒンジピラー4の内部には、エプロンレイン18の後方対面部に車幅方向において車幅方向において内開きコ字状のヒンジレイン70が設けられ、ヒンジレイン70は、上壁71と下壁72との内側フランジ76が、カウルパネル50またはダッシュレイン53の連結部位から後方外側に直線的に傾斜して延設され、上壁71と下壁72との少なくとも一方に折曲げ形成された後側フランジと、ドアヒンジ6が固定される側壁73に折曲げ形成された後側フランジ73Fとが、ドア8内に位置するドア荷重伝達部材84と対面する位置で重合されたことを特徴とする。【選択図】図5
