PROBLEM TO BE SOLVED: To provide a method for producing a tank body which can obtain a very accurate dimension. SOLUTION: An inner surface regulation pin which regulates the inner surface of a delivery pipe is protruded from the side of a parison before mold clamping is completed and is made to penetrate the parison to reach a position corresponding to the inner surface of the delivery pipe. After that, the mold clamping is completed. After high pressure air is charged into the parison to mold a molding, the inner surface regulation pin is extracted from the delivery pipe, and the molding is taken out from a mold.
