ABSTRACT:
A door lock device has a one-motion door opening mechanism. The door lock device comprises a latch mechanism consisting of a latch and a ratchet preventing the latch from reverse-rotating, an outer opening lever, a lock lever, a link operatively placed between the outer opening lever and the lock lever, an inner opening lever connected to the inside opening handle of the vehicular door. The link and the inside opening handle are so connected that the link moves apart from the pressing piece of the ratchet when the inside opening handle excessively rotates. Consequently, when it is at the locked condition and the inside opening handle is operated to open the door, the ratchet is disengaged from the latch and the link is pressed by the pressing piece displacing it to the unlocked position. When the inside opening handle is excessively rotated, the link moves apart from the pressing piece.
