To provide a light-weight fire or smoke-fire shutter sufficiently resisting air pressure, etc., at the time of a fire occurrence, capable of surely preventing the leakage of a smoke and a flame and having a simple structure.
A sealing piece 22c consisting of fire-resisting cloth is installed to a section corresponding to a surface on at least one side of the upper side, left side and right side of a shielding curtain 13 composed of the fire-resisting cloth, an edge section 22c1 on the free end side of the sealing piece 22c is brought into contact with the shielding curtain 13, and the upper side, left side and right side of the shielding curtain 13 are sealed. Supporters 24a, 24a receiving inward force working to a guide bar 23 for the guide apparatus of the shielding curtain 13 through the shielding curtain 13 are mounted into the channel-shaped vertical member 21 corresponding to the upper section of the guide bar 23. Accordingly, the guide bar is not bent inwards even when the force of air pressure, etc., works to the shielding curtain because there are supporters, and the leakage of a smoke and a flame from the periphery of the shielding curtain can be prevented because there is the sealing piece.
