A door lock device has a high degree of freedom in the disposition of an open link for switching between a locked state and an unlocked state and has low operational resistance when being put into the locked state. When there is a malfunction in which the open link is jammed by the dust and therefore does not move from a lock waiting position to an unlock waiting position even when an unlock action is performed, when an outside handle interlock lever is turned, a sliding-contact tilt guide provided on a support body slides and makes sliding-contact with the open link and forcibly tilts the open link, and as a result, it becomes unnecessary to increase an energizing force of a torsion coil spring as a precaution against such malfunction. This makes it possible to reduce the operational resistance when the door lock device is put into the locked state.
