摘要： A parison forming apparatus comprising: a molding die into which a gob is introduced; a plunger 1 entering into the inside of the molding die for forming a parison from the gob together with the molding die; a cylinder that allows the plunger 1 to reciprocally move with respect to the molding die; and a cooling device for introducing cooling air into the inside of the plunger 1 to cool the plunger 1. The base end portion of the plunger 1 is connected to and held by the head of a piston rod 12 of the cylinder via a plunger holding mechanism 2. The plunger holding mechanism 2 has an adapter 21 connected to the head of the piston rod 12, and the adapter 21 is integrally provided with a tubular part 33 having a fitting hole 32 adapted to the cylindrical outer shape of the base end portion of the plunger 1. The base end portion of the plunger 1 is fitted in and held by the fitting hole 32 of the tubular part 33 while a connection ring 22 for connecting the adapter 21 and the base end portion of the plunger 1 fitting on the tubular part 33 of the adapter 21. The inside of the plunger 1 communicates with an air discharge passage through an exhaust passage 27 provided on the adapter 21, and the air discharge passage is configured to communicate with an exhaust device for guiding the air after cooling to the air discharging passage by applying a suction force to the air discharge passage, thereby exhausting the air to the outside.
