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.
