Abstract
A fuel tank production apparatus includes a forming mold and a cooling mold. The forming mold has a protruding ridge portion on a molding surface thereof and is configured to form a primary molded article while forming a bead-shaped portion so as to provide a recess on an outer surface. The cooling mold is configured to cool the primary molded article while crushing the bead-shaped portion by cooling blow pressure and deforming the bead-shaped portion into a rib-shaped portion.
