Abstract
A blow molding apparatus for manufacturing a resin container by blow molding a preform having a bottomed cylindrical shape includes: a pair of mold clamping plates that openably and closably supports a pair of blow split molds accommodating the preform; linear motion mechanisms that drive the pair of mold clamping plates in an opening and closing direction and apply a mold clamping force to the mold clamping plate at a time of mold closing; and a lock member that interferes with a lower end side of the mold clamping plate at a mold closing position of the blow split mold and restricts movement of the mold clamping plate in a mold opening direction.
