The jacket 1 includes cloth body layers 2 and 3 of at least one layer composed of a deformable cloth body for surrounding an inside space 4 of the device 100. A foaming body material 6 is arranged inside the cloth body layers 2 and 3 of at least the one layer for holding a shape. The foaming body material 6 can change its volume to the final target volume larger than that from the initial volume. When the volume of the foaming body material 6 becomes the target volume, the device 100 presents a specified shape, and has the specified function.
