The escape door slides from side to side along a guide rail(1). The automatic closing unit and the holding release unit are respectively provided on both upper sides of a door frame in which the escape door is installed.

The penetration bracket is connected to the escape door, allows the passage of the wire, and contacts the fixing bracket.
