Resin container manufacturing device and manufacturing method

A resin container manufacturing apparatus configured to stretch a preform disposed in a stretch blow molding mold by a stretching rod and stretch the preform by introducing blow air into the preform so as to form a resin container, the resin container manufacturing apparatus comprising:

• a controller configured to switch a blow air introduction operation by selecting any one of a plurality of introduction operations,
• wherein the plurality of introduction operations comprise, at least:
• a first operation in which the blow air is introduced based on a timer;
• and
• a second operation in which the blow air is introduced based on an actual position of the stretching rod.
