PROBLEM TO BE SOLVED: To provide a door device for an elevator capable of coping with insufficiency of driving capacity of a sliding door without requiring an excess installation space. SOLUTION: The sliding door 3 opening and closing an exit 1 is provided, and winding wheels 7 are pivoted to an upper fringe of the exit 1 while they are separated from each other in the horizontal direction to wind an endless transmission strip body 8. The transmission strip body 8 and the sliding door 3 are connected by connection devices 9, 10, and respective winding wheels 7 are driven by electric motors 13, 14. Consequently, the sliding door 3 is driven by a plurality of electric motors 13, 14 through the transmission strip body 8. As a reuslt, it is possible to eliminate a problem of insufficiency of driving capacity of the electric motors caused by specifications of the sliding door 3 and cope with it without increasing the size of the electric motors. It is possible to realize various specifications of the sliding door inexpensively without affecting a basic configuration and requiring extra costs. COPYRIGHT: (C)2004,JPO
