PURPOSE: A mechanical backup structure capable of unlocking a dual locking device of an automobile door is provided to unlock the dual locking status although the power is intercepted. CONSTITUTION: A mechanical backup structure capable of unlocking a dual locking device of an automobile door includes a first locking member, a second locking member, a key box(1), a first key load(10) and a second key load(11). One end of the first key load(10) is connected to the key box(1) to be linearly moved by the rotation of the key and the other end of the first key load(10) rotates the linking structure of the first locking member by the linear movement. And, one end of the second key load(11) is connected to the key box(1) to be linearly moved by the rotation of the key and the other end moves the dual locking member of the second locking member to the dual locking release position by the linear movement.
