Abstract
A shutter has a shutter panel and a pair of guide rails that hold both end portions of the shutter panel slidably. The guide rails have curved portions. Each of the guide rails includes straight members having parallel tie plates and an interval plate connecting central portions of the tie plates resulting in an H-shaped section. Each of the guide rails includes corner members having curved plates succeeding to the tie plates. Both end portions of the shutter panel are inserted slidably between inner half portions of the tie plates partitioned by the interval plates, and outer half portions of the tie plates are mounted to a fixing portion to thereby enable smooth sliding movement of the shutter panel within the guide rails.
