PURPOSE: To reduce in size a vertical driver and a rotary actuator for driving a rotary plate by reducing the wind generated at the time of vertically moving an upper board and the plate as small as possible, decreasing the influence on the temperature of a molding to eliminate the unstable factor of molding, reducing a load with the air resistance at the time of vertically moving to obviate the influence on a molding cycle, and further decreasing in weights the board and the plate. CONSTITUTION: An orientation blow molding machine intermittently conveys a neck die mounted at a rotary plate 20 to a plurality of molding units. The machine has an upper board 16 for supporting the plate 20 above the plate 20 in such a manner that both the board 16 and the plate 20 are together vertically movably supported, holes 60 for allowing the passage of the air at the time of vertically moving via the vertical direction are provided at the board 16 and the plate 20 and provided at the position where the holes 60 coincide at the time of stopping the plate 20. |
