PROBLEM TO BE SOLVED: To prevent water infiltration from outside without a member interfering with passage between guide rails 5, when a shutter curtain 4 of a shutter device of a building is fully closed.SOLUTION: A pressing body 7 is provided that has a first pressing part 7a with a ridge part 7c formed on a groove bottom part 5a of a guide rail 5 and disposed water-tightly on the groove bottom part 5a, and a second pressing part 7b housed inside the guide rail and disposed water-tightly on a floor surface F. A panel part 4g at a bottom edge of a shutter curtain 4 has a waterproof function, and a waterproofing material 8 made of an elastic rubber material is fitted on a side surface 4c and a bottom surface 4d of the panel part 4g. When fully closed, the first and the second pressing parts 7a, 7b elastically deform the waterproofing material 8 for waterproofing the portions. On the other hand, the waterproofing material 8 between the guide rails 5 is elastically deformed by self-weight of the shutter curtain 4 for waterproofing, so that no pressing body is found between the guide rails.SELECTED DRAWING: Figure 6 |
