PROBLEM TO BE SOLVED: To provide a blow molding machine which makes blow core members be set at a refuge position, a seal position, and a waiting position located between them and can quickly seal-attach the blow core members to a neck part. SOLUTION: The blow molding machine molding a container 190 by blow-molding a preform 20 having a ring part 22A protruding outside in the neck part 22 includes a seal part 30A sealing the ring part 22A of the preform 20 airtightly and has the straight liner-moved/guided blow core members 110, 112, 120, 122 and 130 and a driving mechanism displacing the blow core members to the first position of the refuge position, the second position of the seal position, and the third position of the waiting position between the first and second positions. The driving mechanism includes a rod member 140 in which one end is connected rotatably with a fixed end 100A, and the other end is connected rotatably with the blow core member 130 and can adjust the length of the rod member 140 in three stages.
