Abstract
Disclosed herein is a suspension arm component for vehicles with sufficient strength or rigidity to withstand repetitive compressive and tensile forces, and a method for manufacturing such a component by pressing or hemming process alone, without recourse to any welding process, forming quickly and simply, a process with advantages in terms of material yield and cost. The suspension arm component for vehicles includes first flange pieces as well as second flange pieces, and a pair of half members, each having a hat-like shaped cross-section perpendicular to its axis, are joined together to protrude the first flange part and the second flange part from an expanded part, where both the first flange part and the second flange part extend linearly along the axis of the main body part. The main body part presents a rectangular shape in its side view.
