PROBLEM TO BE SOLVED: To enhance a rigidity of a damper base made of an aluminum alloy while avoiding increase in the number of components and a weight.SOLUTION: An upper wall 25a of a damper base 25 has a second opening 25g, into which a vehicle width direction outer end part of a suspension arm 31 of a front wheel can enter, between a first corner part c1 and a first opening 25f. Since two of plural first ribs 25j, which are formed on a top face of the upper wall 25a, pass both sides of the second opening 25g and reaches the first corner part c1, a load, which is inputted from a damper to the first opening 25f of the upper wall 25a of the damper base 25, is transmitted to the first corner part c1 having a high rigidity via the two first ribs 25j, whereby reduction in a rigidity of the upper wall 25a of the damper base 25 due to formation of the second opening 25g can be kept to the minimum while avoiding increase in the number of components and a weight.SELECTED DRAWING: Figure 3

    【課題】 部品点数や重量の増加を回避しながら、アルミニウム合金製のダンパーベースの剛性を高める。【解決手段】 ダンパーベース25の上壁25aは第1角部c1と第1開口部25fとの間に前輪のサスペンションアーム31の車幅方向外端部が進入可能な第2開口部25gを備え、上壁25aの上面に形成された複数の第1リブ25jのうちの2本は第2開口部25gの両側を通って第1角部c1に達しているので、ダンパーからダンパーベース25の上壁25aの第1開口部25fに入力した荷重を2本の第1リブ25jを介して剛性が高い第1角部c1に伝達することで、部品点数や重量の増加を回避しながら、第2開口部25gを形成したことによるダンパーベース25の上壁25aの剛性低下を最小限に抑えることができる。【選択図】 図3
