A blow molding device capable of securely holding a built-in part in a prescribed position in an interior of a blow molded article with a compact equipment. The blow molding device includes a blow mold and a built-in part holding unit. The built-in part holding unit includes a holding rod adapted to hold the built-in part and arranged to freely advance and retreat to be removed from the blow mold. The blow mold includes a slide core in each of two mold members so as to freely advance and retreat relative to a cavity of the blow mold, and a drive control pin in each of mating faces of split two mold members, and the drive control pin and the slide core are linked with a linking member. The slide core is driven with the drive control pin such that when the blow mold is closed, the slide core retreats from an interior of the cavity to a molding surface defining the same at the same speed as the closing speed of the blow mold.
