PROBLEM TO BE SOLVED: To provide a stabilizer drive for guaranteeing the continuous operation via a sub-shaft when a serious failure such as breakage of a main shaft device for transmitting the steering force of an aircraft steering system. SOLUTION: The stabilizer drive has a main shaft device consisting of a cylindrical screw rod with a ball screw formed on an outer circumference, and a nut screwed to the screw rod via a ball, and is provided with an interlocking mechanism for interlocking the operation of the nut in the main shaft device with a wing of an aircraft. The stabilizer driving device comprises a sub-shaft inserted in the screw rod for rotatably holding the screw rod, a detection mechanism for detecting the breakage of the screw rod or a housing when they are broken, and a restriction mechanism for restricting the main shaft device by the sub-shaft by integrally coupling the main shaft device and the sub-shaft with each other by the operation of the detection mechanism. A failure stop mechanism in a stabilizer driving device immediately stops the tail steering force, and ensures the flight safety by mechanically stopping and holding the tail angle at the position immediately after the failure.
