<p>A blow molding apparatus includes an injection molding station (12) that injection-molds a plurality of preforms (1A) held by N (N is an integer equal to or larger than 2) rows of holding plates (30), a temperature control station (14) that performs a temperature control operation on the plurality of preforms (1A), a blow molding station (16) that blow-molds the plurality of preforms into a plurality of containers, and a row pitch change section (130) that changes the row pitch of the N rows of holding plates so that P1<P3<P2 is satisfied, P1 being the row pitch of the N rows of holding plates when they hold the plurality of preforms, P2 being the row pitch of the N rows of holding plates when they hold the plurality of containers, and P3 being the row pitch of the N rows of holding plates when they hold the plurality of preforms that are transferred to N rows of blow molds that are opened.</p> |
