1. A resin-made container manufacturing apparatus comprising:
a clamping mechanism provided independently of a bottom mold of a mold for blow molding, the clamping mechanism being capable of clamping a protrusion provided in a bottom portion of a preform accommodated in the mold for blow molding in a state where split molds included in the mold for blow molding are opened, the protrusion being provided independently of a gate portion;
a moving mechanism configured to move the clamping mechanism such that, in a state where a neck portion of the preform is held, the protrusion is positioned in an outer region of the bottom portion, the outer region being out of a region perpendicularly projected from an opening plane of an inlet-outlet portion of the neck portion; and
a stretch mechanism configured to stretch the preform by a pressurizing medium after the split molds are closed,
wherein the moving mechanism is configured to move the clamping mechanism together with the bottom mold, in parallel to a top plane of the inlet-outlet portion.
