发明名称 車体構成部材の製造装置及び製造方法
摘要 In a vehicle body component, a bent portion that is formed in a component main body made of a metal plate is formed of a thickened portion, in which a plate thickness of the metal plate as a material of the component main body is gradually increased. Just as described, since the bent portion, on which stress is likely to be concentrated when a load is applied to the component main body, is formed of the thickened portion, a plate thickness of a portion where the stress is not concentrated can be prevented from being increased more than necessary. This can contribute to improvement of mass efficiency.
