PROBLEM TO BE SOLVED: To provide a shutter which facilitates mounting of a reinforcing support 15 thereon, and ensures sufficient mounting strength of the support, to thereby improve the negative pressure resistance of the shutter. SOLUTION: According to the structure of the shutter, an upper engaging member 20 is mounted on a horizontal member 16, and a lower engaging member 33 is mounted on a mounting bracket 26 which is arranged on an outside of a sill of a shutter frame 4, followed by arranging rod bodies 43 in the reinforcing support 15 in a manner being protrudable from/withdrawable into upper and lower edges of the reinforcing support 15. Then the reinforcing support 15 has upper engaging member 37 and a lower engaging member 38 arranged on upper lower edges thereof, and the upper engaging member 37 and the lower engaging member 38 of the reinforcing support 15 are slid in a width direction to engage with the upper engaging member 20 of the horizontal member 16 and the lower engaging member 33 of the mounting bracket 26, respectively. Further, at the time of engagement, the rod bodies 43 are protruded from the upper and lower edges of the reinforcing support 15 and engaged with the upper engaging member 20 and the lower engaging member 33, respectively.
