Abstract
A load beam includes a pair of flange bending parts including first bending parts, and a second bending part extending in a width direction. A first cross-section part extends in the width direction of the load beam passing through welding parts. The first cross-section part is warped up toward the flange parts. A second cross-section part extends in the width direction passing through a different position from that of the welding parts. The second cross-section part has a lesser height difference as compared to the first cross-section part. A die is used when bending the second bending part. The die includes a first relief part including a first inclined surface and a second relief part including a second inclined surface in both sides of the supporting surface.
