PURPOSE: A firewall driving motor controller with a locking lever is provided to safely operate a firewall by locking the descending of the firewall by a mechanical operation of the locking lever during the operation of the firewall motor. CONSTITUTION: An extension plate(30) horizontally extends the front end of a push lever(15). A locking lever(40) is movably positioned on the extension plate(30) and has a push bar(41) at the front end to push a firewall motor driving lever. A subsidiary solenoid(50) is operated upon receipt of a signal from a motor at the descending position of the motor driven upon the descending of a firewall. A locking lever operating lever(60) is operated to select a fixed position for fixing the extension plate(30) and the locking lever(40) at ordinary times and a mobile position communicated with the subsidiary solenoid(50) for moving the locking lever(40) to an expansion position by an elastic spring(16) of the motor.
