By removing air from the sign, it can be easily rolled up or folded. However, when using this sign device 10, it is necessary to inject air into the internal space 15c from an air suction port (not shown). By blowing air into the waterproof sheet 15 and sealing it, rigidity can be imparted to the waterproof sheet 15 and flatness can be maintained.

Note that the internal space 15c of the waterproof sheet 15 is as follows:
Preferably, in order to keep the distance between the two sheets 15a and 15b constituting the waterproof sheet 15 substantially constant, an appropriate pattern is formed, for example, as shown in FIG. With the pattern 15d, these two sheets 15a,
15b are brought into close contact with each other. Thereby, the flatness of the waterproof sheet 15 can be further maintained. The two sheets 15a and 15b constituting the waterproof sheet 15 may be adhered to each other in an appropriate pattern so as to divide the internal space into a plurality of parts. By blowing air into
