(54) Unlatching device for vehicle door


(57) An unlatching device for a vehicle door comprises: electrically-operated unlatching means capable of exerting unlatching power; emergency unlatching means capable of transmitting mechanical unlatching power in response to an operation by a vehicle driver; and a latch mechanism configured to enable switching between an unlocked state and a locked state and to release a latched state of a door in response to an operation of any one of the electrically-operated unlatching means and the emergency unlatching means in the unlocked state. A door handle is provided on the door in such a manner as to operate the electrically-operated unlatching means in response to a first operation and to operate the emergency unlatching means in response to a second operation being different from the first operation. Accordingly, it is possible to facilitate an emergency operation in case it is unable to electrically release a latched state of a door due to a malfunction such as a dead battery.
