PROBLEM TO BE SOLVED: To provide a trailing arm structure which sets a folded position of a trailing arm main body to a vertical oblique direction of a bead front end part with respect to an impact from a rear part of a vehicle body, folds a flange or the like to a direction separating from a fuel tank or the like, and is prevented in the damage of the fuel tank or the like.SOLUTION: In a trailing arm structure which supports a pair of left and right trailing arm main bodies to vehicle body sides, bead parts in vehicle body fore-and-aft directions are arranged at plate faces of the trailing arm main bodies 7, curved parts which are downwardly curved are arranged at upper-side flange parts of flange parts which are arranged in vehicle body width directions of the trailing arm main bodies 7, the deepest parts of the curved parts are set at rear positions rather than tips of the bead parts, and lines L which pass vicinities of the tips of the bead parts from the deepest parts of the curved parts are set as folded lines, thus setting folded positions of the trailing arm main bodies 7.SELECTED DRAWING: Figure 1

    【課題】車体後方からの衝撃に対してトレーリングアーム本体の折れ位置をビード前端部の上下方向斜めの方向に設定し、燃料タンク等から離れる方向にフランジ等が折れ曲がるようにし、燃料タンク等の損傷を防止したトレーリングアーム構造を提供する。【解決手段】左右一対のトレーリングアーム本体を、車体側に支持させたトレーリングアーム構造において、前記トレーリングアーム本体7の板面に、車体前後方向のビード部を設けるとともに、前記トレーリングアーム本体7の車体幅方向に設けられたフランジ部の上辺部フランジ部に、下方向に向けて湾曲する湾曲部を設け、前記湾曲部の最深部を前記ビード部の先端部よりも後方位置に設定するとともに、前記湾曲部の最深部から前記ビード部の先端部近傍を通るラインLを折れ線として前記トレーリングアーム本体7の折れ位置を設定したことにある。【選択図】図1
