Therefore, when the operator inserts the drawer 730 into the stop frame, the second elastic member 786 is compressed while the hook member 782 is pushed back by the edge of the drawer 730 and the insertion of the drawer 730 is performed. When completed, the hook member 782 protrudes by the restoring force of the second elastic member 786 and is engaged with the locking groove 784 to restrain the closed state of the drawer 730.

Subsequently, when opening the drawer 730, the hook member 782 may be retracted while the lever member 788 is pulled outward to compress the second elastic member 786, thereby reducing the engagement state of the drawer 730. It can be released.

As a result, when a fire occurs inside the tunnel, people located in the center of the tunnel can easily escape, and it is possible to prevent human injury caused by harmful gas generated inside the tunnel while people are evacuated. If a fire breaks out, a warning message consisting of holographic images is output to the drivers so that drivers who are located far from the fire area can easily recognize the fire and evacuate it. It can be provided.
