Abstract:

Provided is a bulkhead (10), which is a press-molded article, comprising a top plate part (11), side flange parts (14), and corner flange parts (15). The side flange parts (14) respectively extend from each side (12) of the top plate part (11). The corner flange parts (15) respectively extend from each corner part (13) of the top plate part (11). The corner flange parts (15) connect two of the side flange parts (14) to each other. A center part of each corner flange part (15) in the peripheral direction has a section that exhibits a minimum thickness value, and the two side parts thereof each have a section that exhibits a maximum thickness value. The ratio between the maximum value and the minimum value is in the range of more than 1.0 and less than or equal to 1.6. This press-molded article suppresses wrinkling at the corner flange parts, and is suitable as a reinforcing member for an automotive structural member.
