摘要： An inner seal ring 16 is composed by connecting a plurality of inner seal ring pieces 16A, an outer seal ring 17 is composed by connecting a plurality of outer seal ring pieces 17A provided at an outer periphery of the inner seal ring 16, and a coil spring 18 is arranged at an outer periphery of the outer seal ring 17. The inner seal ring 16 and the outer seal ring 17 are piled for two or more stages, respectively. A connecting part of the inner seal ring pieces 16A and a connecting part of the outer seal ring pieces 17 are arranged not to overlap each other. An inner diameter of the inner seal ring 16 is variable in accordance with an outer diameter in vertical direction of a drawing-preform 1 by using a coil spring 18.
