Zusammenfassung:	(Object) To provide a method of manufacturing a resin hollow molded body wherein, predetermined parts can be simply attached when attaching them in the inside of the blow molded hollow body; and the resin hollow molded body, such as a vehicle fuel tank containing a volatile liquid inside thereof, has a good barrier property against a gas component. (Means for solving the problem) There is provided a method for obtaining a product of a hollow molded body characterized in that : a thermoplastic resin parison 6, extruded to a tubular state, is expanded by blow molding; then dies 2, 4 are once divided to assemble predetermined parts 32, 34 inside of the hollow molded body; and the surfaces of the divided dies are joined again.
