Fixation of a container shape of a hollow molded body is not completed during a blow molding process but is completed during an ejection process of an ejection section, thereby shortening an operation time in a stretch blow molding section, and improving the production efficiency of hollow molded bodies by shortening the time required for the blow molding process during a molding cycle. Cooling air is blown into the inside of the hollow molded body disposed in the ejection section in the ejection process C during the blow molding process B in the next molding cycle to cool the hollow molded body disposed in the ejection section to solidify the container shape.
