SOLUTION: A stump part (a leg 60) is enclosed with a plaster cast 64 which is not hardened yet. A flexible sheet mounting part 11 is stuck to the outside of the plaster cast 64 by air pressure, and beads 15 are arranged in an outer cavity part 16. The plaster cast is supported by the beads 15 so as not to sink down even when the load of the leg 60 is applied, and is uniformly fastened by air pressure. In this state, the plaster cast 64 is left for complete hardening. COPYRIGHT: (C)2004,JPO
