Abstract
A manufacturing apparatus for a hat-shaped cross-section component includes a die having first molding surfaces, a pad having a second molding surface, a punch having a third molding surface, a holder having fourth molding surfaces, and a first restraint portion. An upright wall is molded between a top and each of flanges by moving the pad and the punch relative to the die and the holder, or moving the die and the holder relative to the pad and the punch. The first restraint portion is configured to, during a period from when a top forming part is sandwiched by the second molding surface and the third molding surface to when the upright walls are molded, suppress displacement of the top forming part in a longitudinal direction of the top forming part relative to the second molding surface and the third molding surface.
