It is preferable that the extension 151 is connected to the front end of the operation member 150 by a hinge 152 and the extension 151 is bent by a spring so as to bend only in one direction.

In this case, the extension piece 151 is deeply fitted into the operating space 135 between the opening operation piece 121 of the operation opening 120 and the closing operation piece 122 to firmly support the closed state, and at the same time, So that even when the extension piece 151 is caught by the opening operation piece 121 in the closing operation, it passes through while bending and is brought into close contact with the closing operation piece 122 to be initialized.

The operation of the present invention will be described as follows.

First, when the emergency escape door 10 is pushed in a state where the emergency escape door 10 of the fire shutter 1 is closed, the emergency escape door 10 is detached from the stationary vane 110, The operating piece 150 pushes the opening operation piece 122 of the operating member 120 outwardly to release the engagement between the support protrusion 132 of the leaf spring 131 and the resilient ball 133, The resiliently mounted actuating member 120 pivots outwardly and thus the emergency escape door 10 is opened so that the user passes through the fire shutter 1.

Here, when the user passes through the fire shutter 1, it is automatically closed by the emergency escape door 10 due to the elasticity of the spring hinge. At this time, the operation piece 150 is formed longer than the open operation piece 121 Since the elastic force of the resilient force is restrained by the elastic force of the elastic force of the resilient force of the resilient force of the resilient force of the spring 133 .

Accordingly, it is possible to prevent the escapee from escaping due to the fire or to allow the firefighter to smoothly guide the passage of the escape door 10, The bimetal 133 is operated to maintain a more firmly closed state so that the emergency escape door 10 can be maintained in a firmly closed state even in the case of hot air due to fire proximity.
