Zusammenfassung:	PURPOSE: An emergency ladder is provided to allow people to escape from an upper floor to a lower floor by automatically opening a recue box in the event of an emergency in a building. CONSTITUTION: An emergency ladder comprises a handle(151), steel stair plates(152), synthetic fiber for interval adjustment of stair plates(153), a support bar for slip prevention(154), and a band(155). The handle is gripped with hands of a person to go down for escape. The steel stair plates are sliding-spread from a folded state. The synthetic fiber for interval adjustment of stair plates is connected between the stair plates to regulate the interval between the stair plates. The support bar for slip prevention is attached to one side of each stair plate in order to prevent the slip of a person who goes down. The support bar for slip prevention is connected to a wall rail(170) which is formed of a C-shaped channel member. The band is arranged to encircle the stair plates.
