This is an emergency escape device for prevention of burglary and for escaping from a window on a building wall. Because this emergency escape device provides the design of guiding portions on a plurality of fixed seat assemblies and movable seat assemblies, it reduces the vibration and noise problems caused by strong wind. Also, when in use under emergency conditions, the escape ladder assembly can be extended down from a window. Because of this emergency escape device provide special designs on these fixed seat assemblies and movable seat assemblies, they can afford more impact forces when the escape ladder assembly is extending. This prolongs the safety and life of the device.
