PURPOSE:To simplify the structure of a sliding door by slidably installing a plurality of sliding doors respectively different in the moving distances on a guide rail and juxtaposing a plurality of driving shafts along the direction of sliding while providing a single power means. CONSTITUTION:A driving shaft 13 corresponding to one pair 1a, 1b of sliding doors and a driving shaft 14 corresponding to the other pair 2a, 2b are set up to the upper section of a guide rail 4, from which the sliding doors 1a-2b respectively different in the moving distances are suspended. A right end is supported by a power means 15 and a left end by a bearing 17, and the driving shafts 13, 14 are synchronized and turned by the power means 15 and a turn- over device 16. The screws of leads proportional to each moving distance of respective sliding door 1a-2b are notched to each driving shaft 13, 14, and a piece to be driven 18 is screwed to the driving shafts 13, 14. Accordingly, the sliding doors different in the moving distances can be synchronized and opened and closed. |
