PROBLEM TO BE SOLVED: To provide a new apparatus for producing a hollow molding which can accurately mold the wall thickness and inside diameter of an end part and can automatically mold the three-dimensional hollow molding. SOLUTION: The apparatus has an injection molding mold 2 for molding a parison, an injection molding machine 3 for charging a molding material into the mold 2, a blow molding mold 4 which houses the molded parison and expands the intermediate part of the parison by air blowing, and a parison transfer device 5 which demolds the parison molded by the injection molding mold 2 and houses it in the blow molding mold 4. The parison transfer device 5 has one arm 21 in which one core member 23 inserted inside from one end side of the parison is arranged, the other arm 22 in which the other core member 24 inserted inside from the other end side is arranged, and a controller 25 for controlling the arms 21 and 22 separately.
