Abstract

A vehicle door lock assembly having a housing to be secured to a vehicular door structure. The housing has a dent extending along an about up-and-down direction, a striker secured to the vehicular body, a latch rotating from its open position to its fully locked position through its half-latched position, a ratchet preventing the latch from reverse-rotating, a motor functioning when the latch rotates to the half-latched condition, and a lever driven by a motor in order to engage with the latch positioned at the half-latched position so as to rotate the latch to its fully latched position. The lever, latch and ratchet are operative arranged in the dent of the housing along an up-and-down direction and secured to the housing wall by three parallel shafts.
