Moreover, since it becomes possible to form the door panels 14 and 16 long, it becomes possible to make the space | interval with the door pocket body 12 of the adjacent platform door apparatus 10 wider. As a result, the width (opening width) of the getting-on / off passages 17 and 18 can be formed wider.

  Further, in the present embodiment, the upper cover portion 23a of the emergency escape door portion 23 exists above the door bottom movement path of the first door panel 14 and the door bottom movement path of the second door panel 16, and the movement path Since the side surface covering portion 23b exists on the home side, the first door panel 14 is driven so that the door butt protrudes from the first support portion 21, and the door butt protrudes from the second support portion 22. Even if the door panel 16 is driven, passengers can be prevented from touching the door panels 14 and 16. Therefore, the safety of passengers can be improved.

  Further, in the present embodiment, the first door panel 14 and the second door panel 16 are displaced in the thickness direction of the door panel, and the door bottom of the first door panel 14 protruding from the first support portion 21 and the second support portion The door butt of the second door panel 16 protruding from 22 overlaps in a state viewed from the track side. For this reason, since the space | interval between the 1st support part 21 and the 2nd support part 22 can be narrowed, it can also install in the platform where the vehicle with a narrow door pitch enters.

  Moreover, in this embodiment, since a part of drive motor 48a, 58a is arrange | positioned in the thickness range of the door panels 14 and 16, the door pocket body 12 can be made thinner.

Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention .

  In the above-described embodiment, the emergency escape door portion 23 includes the upper cover portion 23a and the side cover portion 23b.
