This mold device has a rotary core that rotates about a shaft member as a rotation center by being provided with a rotational driving force directly from a rotation driving means. A restriction core is interposed between the rotary core and a mold body to restrict the rotation of the rotary core. That is, the rotary core becomes rotatable when the restriction core is withdrawn from between the rotary core and the mold body.
