PROBLEM TO BE SOLVED: To provide a light-weight and highly rigid lower arm provided to a front suspension device.SOLUTION: The shaft centers L2 of vehicle body side shaft supports 31f, 31r of front and rear sides that are supported to the vehicle body side of a lower arm 3 both extend in a vehicle longitudinal direction. A rear arm 34 provided to the rear side of the lower arm 3 extends forward by detouring in a projected chevron shape in order to prevent tire interference. A vertical wall 37 that vertically extends and a horizontal rib 38 that is thinner in a vertical direction than the vertical wall 37 and that projects in a cross direction are further provided. The vertical wall 37 is straightened to extend so as to be closer to a vehicle width reference line Lw than the ridge lines of the front and rear edges 34f and 34r of the rear arm 34.SELECTED DRAWING: Figure 7
【課題】フロントサスペンション装置に備えたロアアームを軽量高剛性化すること。【解決手段】ロアアーム3の車体側へ軸支する前後各側の車体側軸支部31f,31rの軸心L2が前後ともに車両前後方向に延びており、ロアアーム3後側に有する後側アーム部34は、タイヤ干渉防止の為に前方へ凸のくの字状に迂回して延びており、さらに上下方向に延びる縦壁部37と、該縦壁部37よりも上下方向の肉厚が薄く前後方向に突出する水平リブ38とが設けられ、縦壁部37を、後側アーム部34の前縁34fおよび後縁34rの各稜線よりも車幅方向基準線Lwに近づくように直線化して延設した。【選択図】図7
