A shutter structure is provided to prevent the separation of a slat from a guide rail even if a slat is deformed by a strong wind by installing a slat locking device to make one side fixed to a slat and the other side inserted to a guide rail and coupled to a hanging projection of the guide rail dually. A shutter structure is formed for preventing the separation of a slat(305) from a guide rail groove by installing a slat locking device(320) to two ends of each slat to be suspended on a guide rail groove when a slat is bent by a strong wind. The slat locking device is placed for one side to be inserted to the slat to the part of a projection(321) and the other side to be formed in the T-shape to be inserted to a guide rail(330) to slide and couple with the guide rail, and provided with holes(324) formed on the T-shaped two sides(322) and fitted with a spring(325) and a ball(323) to make the two sides contact with an internal wall(331) of the guide rail using repulsive force of the spring, and one side of the guide rail is closed and fixed to a column and the other side is opened, installed to be opposite to the slat and fixed with the slat locking device to slide and couple with the slat, wherein the opened side of the guide rail is formed to be narrower than the T-shaped side of the slat locking device and to make the T-shaped side of the slat locking device contact with the internal wall of the guide rail and suspended on an hanging projection(333) formed on the opening of the guide rail to prevent the separation of the slat locking device. |
