An injection stretch blow molding apparatus includes a lower base which is secured on a stage, an upper base which is disposed above the lower base and supports a turntable, and vertical clamping device that raises and lowers the upper base with respect to the lower base. The vertical clamping device includes a pulling plate disposed in the stage under the lower base, a plurality of tie rods which pass through the lower base and connect the upper base and the pulling plate, a vertical clamping toggle mechanism which is disposed in the stage at a position under the injection molding section and expands and contracts with respect to the lower base as a reference position to raise and lower the pulling plate, and a first motor which transmits a driving force to the vertical clamping toggle mechanism.
