ABSTRACT:
A door lock device is mounted, for example, on the door of a motor vehicle such that, when a latch of the door lock device is moved to a half latch position where it barely engages a striker fastened, for example, to the vehicle body, a drive device is operated to forcibly move the latch to a full latch position where it is completely engaged with the striker. The door lock device includes a close lever coupled to the drive device and movable from a non-operation position to an operation position, and a sub-pole coupled to the close lever and movable between an engaging position where it is engaged with the latch and a releasing position where it is disengaged from the latch. The sub-pole engages the latch to move the latter to the full latch position in response to movement of the close lever to the operation position, and is moved to the releasing position upon movement of a door handle provided on the door. When the door handle is operated while the latch is being moved from the half latch position to the full latch position through the close lever and the sub-pole by the drive device, the sub-pole is disengaged from the latch to cause the latch to be disengaged from the drive device so that the door can be opened immediately.
