摘要： PROBLEM TO BE SOLVED: To provide a door opening/closing device for a platform capable of being stably opened/closed in which rails provided on a pair of right and left slide doors respectively are mounted at the same height and rear end parts of the rails are not crossed to each other. SOLUTION: The door opening/closing device for the platform includes: a slide door for opening/closing a doorway port on the platform; a shutter box of narrow width; and an emergency opening/closing partition plate between the pair of right and left shutter boxes. A door tail side of the rail mounted to the slide door is made to a rail extension part, and a door tail side of an upper frame is made to an upper frame extension part. The lengths of them are made to lengths approaching to each other near a center line of the emergency opening/closing partition plate at release of the pair of right and left slide doors. A slide block for horizontally moving the rail is mounted at the inside of the shutter box. Into a transom of the shutter box, a door distal end descending prevention means is provided facing the upper frame extension part. A drive means for opening/closing the slide door by pulling a drive belt laid on both ends of the slide door to right and left sides is provided. COPYRIGHT: (C)2010,JPO&INPIT
