PROBLEM TO BE SOLVED: To improve the durability of a shutter body 10 by increasing the coupling strength between each slat 2 in a rolling door shutter, which has the shutter body 10 comprising slats 2 of rectangular plates and hinges 3 provided in a row arrangement on the edges of the long sides of the slats 2 and coupling each slat 2 in a bending-free manner, and a pair of guide rails 7, 7 holding both the end of the shutter body 10 in a sliding-free manner. SOLUTION: On both the end of the shutter body 10, a link plate continuous body 4 is provided for coupling adjacent hinges 3, 3 together. In the link plate continuous bodies 4, each end of adjacent inner link plate 41 and outer link plate 42 is linked together so that both the ends swing on the common hinges 3 freely.
