摘要

To provide a heat-insulating vessel structure with a high degree of freedom in strength design of an inner wall by reducing the stress of the inner wall.SOLUTION: A heat-insulating vessel structure comprises a cylindrical storage body for storing a workpiece inside, and a pair of lids for closing openings at both ends of the storage body. Each of partition walls of the storage body and the lids is formed by an inner wall and an outer wall arranged outside the inner wall, and a vacuum layer is formed between the inner wall and the outer wall so as to perform heat insulation. In the storage body, connection means for connecting and mutually pulling the pair of lids is provided.SELECTED DRAWING: Figure 1
