PROBLEM TO BE SOLVED: To provide a seal structure of a lid in a centrifugal mold capable of certainly sealing the opening of a mold main body even if a locking device having a simple structure and a simple machanism is used. SOLUTION: A seal plate 32 for covering the opening of the tubular part of the mold mainbody 11 is provided to the inner surface of the lid 12, which closes the opening of the mold main body 11 in the centrifugal mold for centrifugally molding a hollow cylindrical body, so as to be movable in the axial direction of the mold and energizing means (pressure contact springs 34) for energizing the seal plate 32 toward the opening of the tubular part are provided.
