PROBLEM TO BE SOLVED: To provide an emergency shutting driving device 13 capable of being miniaturized by compacting a detachable mechanism 14 section to arrange. SOLUTION: The detachable mechanism section 14 includes a supporting spring 23 supported by a box bottom wall 18, a supporting body 21 energized by the supporting spring 23, a detachable spring 24 supported by a supporting body 21 and a locking body 22 energized by the detachable spring 24. In a normal state, the locking body 22 is locked with the supporting body 21 by a locking arm 25, and the supporting body 21 is positioned by an operating means 36 in the case of a normal time. An interlocking body 41 making an opening and shutting driving device of an opening and shutting machine as a state capable of shutting driving is in a normal state position P. When the locking of the locking arm 25 to the supporting body 21 is released by excitation of an electromagnetic solenoid 30, the locking body 22 is moved by the detachable spring 24 to become an emergency state, and the interlocking body 41 is in an emergency state position Q. When the positioning of the supporting body 21 is released by the operating means 36 in the case of the normal time, the supporting body 21 is moved by the supporting spring 23 to make the interlocking body 41 as an operating state position R in the case of normal time.
