<P>PROBLEM TO BE SOLVED: To provide a door opening-closing device of an elevator capable of reducing the number of parts. Ž<P>SOLUTION: This door opening-closing device of the elevator is provided for transmitting driving force of a motor 4 to a door via a link mechanism 6, and includes: a speed detecting means 7 removably arranged in the door 1; a processing means for arithmetically operating a door speed and a doorway width based on output of the speed detecting means 7 and arithmetically operating the reduction gear ratio of the link mechanism 6 by comparing these data with a motor rotating speed; and a storage means for storing reduction gear ratio data. Thus, the reduction gear ratio data provided via the speed detecting means 7 in trial operation, is stored in the storage means, and is reflected on door opening-closing control of ordinary operation. The speed detecting means 7 is removed after the trial operation, and is diverted for renewing the other elevator. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
