Abstract
A shutter includes a shutter panel 10 having a plurality of plates 1 which are rotatably connected to one another by hinge members 2, and a pair of guide rails 4 formed with guide grooves 40 which slidably hold opposite end edges of the shutter panel 10. By using the hinge members 2 which connect the adjacent plates 1 to each other so that the plates are rotatably bent only in a direction in which a curvature becomes greater than a portion of the guide groove 40 having a minimum curvature, it is possible to smoothly open and close the shutter even when the curvature of the guide rail 4 is varied along the sliding direction of the shutter panel 10.
