Abstract
A vehicle door latch device comprises a latch that can engage with a striker; a ratchet that engages with the latch to hold a door closed; a stationary stopper; a first lever pivotally mounted on a first shaft to rotate from an initial position in a releasing direction; a first spring that biases the first lever toward the initial position, a second lever supported to the first lever on a second shaft and rotating between an initial position where the second lever cannot contact the stationary stopper and a blocking position where the second lever can contact the stationary stopper and prevents the first lever from rotating in the releasing direction; and a second spring that biases the second lever toward the initial position with a force greater than a biasing force of the first spring.
