照）。2. Description of the Related Art A resin fuel tank of this type is generally formed on the basis of a blow molding method. When air is blown into a parison to expand it, a part of the parison is relatively inwardly moved using a slide core or the like. Into a baffle portion together with the tank body by pushing the tank body into a partition shape (for example, JP-A-63-258750, JP-A-2-47036, JP-A-4-1033).

く結果となって好ましくない。Since the baffle is formed by pressing a part of the parison relatively inward as described above, the tip of the formed baffle is stretched most often. It has to be thin. Therefore, in order to maintain the required strength even at the tip of the relatively thin baffle part, the thickness of the entire parison, and hence the thickness of the tank itself, must be increased, resulting in a significant increase in weight. This results in undesirable results.
