PROBLEM TO BE SOLVED: To provide a parison bending device for a blow molding machine which can improve the cutting of burrs in the bottom part of a molding made of a bent neck container and the quality of the molding and curtail an equipment cost and maintenance by simplifying the structure of a mold including the parison bending device. SOLUTION: The parison bending device has a lift 30 which is positioned below the mold 1 and fitted to a mold moving apparatus 73 and swing devices 20 and 30 which are integrated with the lift 30 and swing the parison 81 grasped by a pair of grasping members 12 of a parison grasping device 10. The parison 81 is bent by swinging the parison grasping device 10 by the swing devices 20 and 30 while the lower end part of the parison 81 is grasped by the grasping members 12 of the parison grasping device 10 elevated by the lift 30, and the parison 81 is supported in the space of the cavity 2a of the mold 1.
