Abstract
A shutter includes a shutter panel having a plurality of plates which are rotatably connected to one another by hinge members and a pair of guide rails formed with guide grooves which slidably hold opposite end edges of the shutter panel By using the hinge members which connect the adjacent plates 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 having a minimum curvature, it is possible to smoothly open and close the shutter even when the curvature of the guide rail is varied along the sliding direction of the shutter panel
