ABSTRACT:
The invention concerns a door structure for an elevator which allows a service engineer to easily adjust a gap between a vibration damping engaging mechanism on a cage sliding door, the width of which varies through the opening/closing operation of the cage sliding door, and each of vibration damping members spaced predetermined distances apart from both sides of the vibration damping engaging mechanism. In the door structure, the vibration damping engaging mechanism includes movable engaging vanes spaced predetermined distances apart from the vibration damping members. The movable engaging vanes are operated such that when the sliding door is present near to the full close and open positions, the spaces are larger than those when the sliding door is present in the middle of the opening/closing stroke of the sliding door.
