FRONT PART VEHICLE BODY STRUCTURE OF VEHICLE

To provide a front part vehicle body structure of a vehicle which reinforces a portion in which a load from an impact absorption member is input to exert stress on a cross member support part and a reinforcement space is not secured by an upper arm and which inhibits occurrence of blow holes (hole-like defects occurring in a casting) to stably secure strength of a structure.SOLUTION: A front part vehicle body structure of a vehicle includes suspension housings 30 each of which is formed by a casting in which suspension damper support parts 34, upper arm support parts 35, and lower arm supports part 36 are formed. Each suspension housing 30 supports an impact absorption member 40 on its front surface and has a thick plate part 30A where a cross member 31 increases a thickness of a portion, in which the upper arm support parts 35 are provided at the outer side in a vehicle width direction, compared to other portions, at the inner side in the vehicle width direction. A dimple processing part 37 is formed at the thick plate part 30A.SELECTED DRAWING: Figure 12 【課題】衝撃吸収部材からの荷重が入力され、クロスメンバ支持部に応力がかかり、かつ、アッパアームにより補強スペースが確保できない部位を補強すると共に、巣（鋳造品に生ずる穴状欠陥）の発生を抑制して構造体の強度を安定して確保する車両の前部車体構造の提供を目的とする。【解決手段】サスペンションダンパ支持部３４と、アッパアーム支持部３５と、ロアアーム支持部３６とが形成される鋳造品から成るサスペンションハウジング３０を備えた車両の前部車体構造であって、サスペンションハウジング３０は、衝撃吸収部材４０を前面に支持すると共に車幅方向内側にクロスメンバ３１が、車幅方向外側に上記アッパアーム支持部３５がそれぞれ設けられる部位の板厚を、他の部位よりも厚くした厚板部３０Ａを有しており、上記厚板部３０Ａにはディンプル加工部３７が形成されたことを特徴とする。【選択図】図１２
