Abstract
A door lock device includes a latch mechanism, a lift lever, an open lever, a lock lever including a main lever and a sub lever mounted on the main lever so as to relatively rotate thereto, a biasing member disposed between the main lever and the sub lever, and an open member. When the open member is in the unlocked position, the open member engages with the lift lever by an operation of the open lever in one direction thereby allowing the lift lever operable. When the open member is in the locked position, the open member idly engages with the lift lever by the operation of the open lever and then becomes engaged with the lift lever in the other direction thereby prohibiting the lift lever operable when the open member is switched to the unlocked position from the locked position.
