PURPOSE: To prevent vibration motions around a wheel axis by comprising a rotatably driven wheel, a blow molding station at an outer periphery of the wheel, a blow mandrel which carries a parison in the blow molding station for the blow molding and by rotatably supporting the wheel in an outer periphery bearing. CONSTITUTION: A wheel ring 10 comprises a beam 16 and flanges 17, 18 and is supported by ribs 19, 20 and the outer periphery of the ring 10 comprises a bracket 22 including a horizontal flange 23. An outer ring 28 of a bearing means 12 is secured to the flange 23 and supports an outer ring 29 for camming with a drive means. An inner bearing ring 30 is secured to a stationary base 14 and a plurality of ball members are provided between rings 29, 30. A blow molding station 11 is mounted on the flange 17 and a blow mandrel 42 supporting a parison (V) is inserted into the blow molding station 11 so as to be supported on a holder 43. This constitution enables elimination of the vibration while turning around and a proper delivery of the parison. |
