Zusammenfassung:	[PURPOSE] To provide a door opening and closing driving apparatus for a door apparatus for a platform for track vehicles (10,11) which can freely adjust the position and the width at and with which doors are to be opened and can vary the direction and the stroke in and over which the doors are to be opened and closed. [CONSTITUTION] Driving rollers (51 to 55) which rotate with intersecting angles with respect to driven rollers (3A,3B) provided on doors (1A,1B and so forth) are contacted with the driven rollers (3A,3B), and the sliding doors are opened and closed by movement of the driven rollers. The distance between opening and closing driving sections (41 to 45) provided with the driving rollers (51 to 55) is set to a distance smaller than the length of the driven rollers (3A,3B), and an opening of any of various sizes can be formed without being limited by the width dimension of the doors.
