PROBLEM TO BE SOLVED: To provide a front part vehicle body structure of an automobile which can enhance both rigidity at a collision of a vehicle and rigidity to engine vibration while achieving cost reduction and weight reduction.SOLUTION: A front part vehicle body structure of an automobile comprises: a rigid member 12 for connecting an apron member 4 and a side member 2; a main body part 12c which forms a closed cross section a extending to a substantially-vertical direction by using the apron member 4; and fore-and-aft flange parts 12d, 12e which are integrally arranged at an external edge of the main body part 12c so as to be bendable. At least a lower end part 12b has a fore-and-aft width w which passes between fore-and-aft engine mount fastening members 10, 11. Then, the rigid member 12 is extended up to a middle part of the side member 2 in a vertical direction, and connected to the middle part, and the fore-and-aft flange parts 12d, 12e of the rigid member 12 are connected to the side member 2 together with the fore-and-aft engine mount fastening members 10, 11.SELECTED DRAWING: Figure 1
【課題】低コスト化,軽量化を図りつつ、車両衝突時の剛性及びエンジン振動に対する剛性の両方を高めることができる自動車の前部車体構造を提供する。【解決手段】エプロンメンバ4とサイドメンバ2とを連結する剛性部材12を、エプロンメンバ4とで大略上下方向に延びる閉断面aを形成する本体部12cと、該本体部12cの外縁部に一体に屈曲形成された前,後フランジ部12d,12eとを有し、かつ少なくとも下端部12bが前記前,後のエンジンマウント締結部材10,11間を通る前後幅wを有するものとする。そして前記剛性部材12を、前記サイドメンバ2の上下方向中途部まで延長するとともに該中途部に結合し、前記剛性部材12の前,後フランジ部12d,12eを、前記前,後エンジンマウント締結部材10,11とともにサイドメンバ2に結合した。【選択図】図1
