Abstract
In a suspension member having a closed cross section, insertion holes are respectively formed in an upper member and a lower member that are two opposing walls. A collar includes a cylindrical portion and a flange. The cylindrical portion is inserted through the insertion holes. On the upper member side, the cylindrical portion and the upper member are welded together, forming a weld bead. On the lower member side, the outer circumferential edge of the flange and the lower member are welded, forming a weld bead. The welding is applied so that the length of the welding line on the lower member side is longer.
