To allow the come-off of a front wheel from a vehicle body at a collision without installing a fragile part such as a notch at a lower arm.SOLUTION: A first bracket 44A for supporting a first lower arm 12A comprises a front wall part 50A and a rear wall part 52A which oppose a vehicle fore-and-aft direction. Insertion holes in which support bolts 46A for supporting the first lower arm 12A so as to be turnable are oppositely formed at the front wall part 50A and the rear wall part 52A. Furthermore, at the front wall part 50A, a fracture start point is formed in a region at the outside of the vehicle fore-and-aft direction from a center of the insertion hole.SELECTED DRAWING: Figure 3
【課題】ロアアームに切り欠き等の脆弱部を設けることなく、衝突時における車体からの前輪の離脱を可能とする。【解決手段】第一ロアアーム12Aを支持する第一ブラケット44Aは、車両前後方向に対向する前壁部50A及び後壁部52Aを備える。前壁部50A及び後壁部52Aには、第一ロアアーム12Aを回動可能に支持する支持ボルト46Aが挿入される挿入孔がそれぞれに対向して形成される。さらに前壁部50Aには、挿入孔の中心から車両幅方向外側の領域に破断起点部が形成される。【選択図】図3
