PROBLEM TO BE SOLVED: To provide a rain shutter door device which is prevented from wobbling and toppling of rain shutter doors, and operable only by applying small opening/closing power. SOLUTION: According to the structure of the rain shutter door device, the rain shutter doors 5 are slidably openably supported by a head 3a via an upper slide rail 4, and also slidably openably supported by a sill 3b via a lower slide rail 30. Therefore the rain shutter doors 5 are held by the upper and lower slide rails 4, 30 in a manner protruding outward from both jambs 3c, 3c when fully opened. As a result, wobbling and toppling of the rain shutter doors 5 are prevented, and power necessary for opening/closing the doors is reduced. COPYRIGHT: (C)2007,JPO&INPIT
