Abstract
A door lock device includes a latch mechanism, a lift lever, an open lever, a lock lever, an open member including a link member having an operation input portion connected to the open lever and an acting portion engageable with the lift lever, and an elastic member connecting the link member and the lock lever. 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 an operation of the lift lever. 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 operation of the lift lever when the open member is switched to the unlocked position from the locked position.
