  • Patent number: 10988004
    Abstract: A press forming apparatus that produces a character line in a design surface of an outer panel by press forming includes an upper die and a lower die. The upper die has a die surface that is configured to form a design surface of an outer panel. The lower die has a die surface corresponding to the die surface of the upper die. The die surface of the lower die has, in a formation area of the character line, a curved convex portion that protrudes beyond an offset line of the die surface of the upper die and curved concave portions continuous with the curved convex portion. Each of the curved concave portions is on a corresponding one of both sides of the convex portion and is recessed beyond the offset line.
