FIELD: transport machinery.
SUBSTANCE: invention relates to vehicle body component, such as a car, manufacturing device of the same, and manufacturing method for the same. 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.
EFFECT: as a result, it is possible to avoid an increase beyond the need for the thickness of the sheet portion where the stress is not concentrated, thereby increasing the weight efficiency.
