PROBLEM TO BE SOLVED: To enhance a support rigidity of a damper base made of an aluminum alloy for a vehicle body made of a steel plate.SOLUTION: A vehicle width direction outer wall 16b of a front side frame 16 and a vehicle width direction inner wall 18f of an upper member 18 are connected to each other by a damper base 25 made of an aluminum alloy, a bulk head 32 in a lower member 19 is located in the interior of a portion at which a front bulk head upper side 24 is connected to the lower member, and a bulk head 26 in the upper member 18 is located in the interior of a portion at which a rear end of the damper base 25 is connected to the upper member. Therefore, even if a rigidity of the damper base 25 made of the aluminum alloy is higher than that of the upper member 18 and the lower member 19 which are made of a steel plate, and a load inputted to the damper base 25 from a damper can be efficiently transmitted to the upper member 18, the lower member 19 and the front bulk head upper side 24, and can be supported.SELECTED DRAWING: Figure 2
【課題】 鋼板製の車体に対するアルミニウム合金製のダンパーベースの支持剛性を高める。【解決手段】 フロントサイドフレーム16の車幅方向外壁16bとアッパーメンバ18の車幅方向内壁18fとがアルミニウム合金製のダンパーベース25で連結され、ロアメンバ19にフロントバルクヘッドアッパーサイド24が接続される部分の内部にロアメンバ内バルクヘッド32が配置され、アッパーメンバ18にダンパーベース25の後端が接続される部分の内部にアッパーメンバ内バルクヘッド26が配置されるので、アルミニウム合金製のダンパーベース25の剛性が鋼板製のアッパーメンバ18およびロアメンバ19の剛性よりも高くても、ダンパーからダンパーベース25に入力した荷重をアッパーメンバ18、ロアメンバ19およびフロントバルクヘッドアッパーサイド24に効率的に伝達して支持することができる。【選択図】 図2
