In a metallic mold apparatus, a rotational power for a skewing operation and a rotational power for an indexing operation are applied through a differential gear device to a rotatably supported die. More specifically, the skew power from such an electric motor as a servomotor operative in synchronism with a press operation and the indexing power from an index means operatively coupled to a press are applied to the differential gear device.
