Abstract
A vehicle door lock device comprises a first group lever consisting of three kinds of ratchet levers connected to a ratchet, and a second group lever consisting of two kinds of opening levers connected to an outer opening handle. First variation of the lock device having one-motion opening and self-canceling mechanisms can be realized by the first combination of a first ratchet lever and a first opening lever. Second variation of the lock device having one-motion opening mechanism but self-canceling mechanism can be realized by the second combination of a third ratchet lever and the first opening lever. Third variation of the lock device having self-canceling mechanism but one-motion opening mechanism can be realized by the third combination of a second ratchet lever and a second opening lever.
