Abstract:

To provide a shutter curtain closing side tip structure of a shutter system which can eliminate separation of an end item such as a bearing plate from a mating member when a shutter curtain is brought into a closed state, and which can secure airtightness by the end item and the mating member.

The shutter curtain 30 closes and moves downward, and forms a disaster-prevention partition when it is fully closed. The end item 51, which is provided to the tip on the closing side of the shutter curtain 30, is constituted by a contact member 61 and a moving member 62, and the contact member 61 is brought into contact with a floor 5 which is its mating member. Part of the moving member 62 is inserted into the hollow-shaped interior of the contact member 61, and the moving member 62 is made possible to move in the upward direction including the slanting upward direction with respect to the contact member 61. Then, the descent of the moving member 62 after the contact member 61 has been brought into contact with the floor 5 stops when the undersurface of the moving member 62 has been brought into contact with the lower surface part of the contact member 61.
