Abstract:
1. A vehicle door latch device comprising: an outer open lever displaceable to an actuated position Y from a stand-by position X in response to an opening operation of an outside open handle of a door; an inner open lever arranged to displace the outer open lever when rotated by an opening of an inside open handle of the door; a lock lever for connection to an inside lock button of the door and displaceable between an unlocked position U and a locked position L; an open link arranged to be displaced into an engaging position in which displacement of the outer open lever is transmitted to a ratchet pin of a ratchet when the lock lever is in the unlocked position U and to be displaced into a disengaging position in which the displacement of the outer open lever is not transmitted to the ratchet pin of the ratchet when the lock lever is in the locked position U; a hook lever provided on the inner open lever for switching the lock lever residing at the locked position L to the unlocked position U in response to the rotation of the inner open lever; and a pressing spring connecting the lock lever and the open link; wherein when switching the lock lever to the unlocked position U from the locked position L while the outer open lever is in the actuated position Y, the pressing spring is compressed although the open link is not displaced to the engagement position; wherein the outer open lever is returned to the stand-by position X at the time of the state where the pressing spring is compressed, the open link is pushed out toward the engaging position by elasticity of the pressing spring.
