るブロー成形装置。[Scope of Claim for Utility Model Registration] A preformed parison is sandwiched between a pair of molds to create a completely sealed structure inside the parison, and then a pipe-shaped air blow nozzle is inserted into the parison through a guide hole formed in the mold. In a blow molding device that is inserted to blow air into the inside of the parison, the tip of the air blow nozzle is formed to be sharp, and the air is directed in the radial direction of the air blow nozzle onto a peripheral wall near the tip of the air blow nozzle. A blow molding device characterized by forming an air outlet for blowing air.
