ABSTRACT:
A car door apparatus of an elevator includes a pair of door panels, a door drive device, and a door-opening mechanism. The pair of door panels open and close a doorway of the car of the elevator. The door drive device drives the door panels to open and close the doorway using electric power. When the car is stopped in an emergency in which a power source for driving the elevator is shut off, the door-opening mechanism starts up the door drive device using a secondary battery to move the door panels in the opening direction by a predetermined distance respectively to make a predetermined clearance between the door panels.
