Abstract
A door locking device includes: a latch mechanism detachably engageable with a striker; an opening lever rotatable interlockingly with a manipulation of a door handle; a transmission member swingable between an unlocking position and a locking position; and a spring member biasing the transmission member from the locking position toward the unlocking position. The spring member allows the movement of the transmission member from the unlocking position toward the locking position in a state where a force of inertia equal to or more than a set value acts on the transmission member. The door locking device also includes a restricting portion restricting biasing of the transmission member toward the unlocking position by the spring member when the transmission member is moved to the locking position against a biasing force of the spring member.
