Abstract
In order to provide a firewall that is capable of preventing flame passage through a through-hole without any sealant in a connecting part of a component in which a fastener through-hole is formed, a firewallis provided which can prevent a flame from leaking out of the connecting part which connects a first memberto a second member, particularly through the fastener through-hole TH defined therein. In the firewall, the connecting part is a part of a fire-protection chamber. As sealing piecesandwhich also constitute a part of the fire-protection chamberare in contact with each other, the flame is unable to enter into a closed space CA. Thus, the flame would not reach the connecting part, thereby preventing the flame from leaking out of the firewallto the outside of a nacelle
