A suspension member includes a side rail. The side rail is formed in a closed sectional structure by combining an upper member, a lower member, and a reinforcing member located between the upper member and the lower member. The upper member and the reinforcing member are fixed by welding and form a closed cross section having an upper hollow portion. The reinforcing member and the lower member arefixed by welding and form a closed cross section having a lower hollow portion. A distance from an upper end to a lower end of the upper hollow portion in a vertical direction in the lower bending portion is longer than that in the upper bending portion, and a distance from an upper end to a lower end of the lower hollow portion in the vertical direction in the upper bending portion is longer than that in the lower bending portion.
本发明的悬架梁具备在车辆前后方向延伸的边梁。所述边梁由上构件、下构件以及位于所述上构件与所述下构件之间的加强构件组合而形成为闭合截面构造。所述上构件和所述加强构件通过焊接来固定,形成具有上中空部的闭合截面。所述加强构件和所述下构件通过焊接来固定,形成具有下中空部的闭合截面。所述上中空部的从上端起到下端为止的上下方向距离在所述下曲部处比在所述上曲部处长,所述下中空部的从上端起到下端为止的上下方向距离在所述上曲部处比在所述下曲部处长。
