An emergency scrolling door opening device includes a body, a pivotal unit and a transmission unit. The pivotal unit is pivotally connected to inside of the body. The transmission unit extends through the body and drives the pivotal unit. The transmission unit has a lock which can be unlocked by using a key so as to allow the transmission unit to drive the pivotal unit and operates the clutch in the scrolling door to disengage the clutch from the motor and the scrolling door, therefore, the scrolling door can be operated manually when no electric power is available.
