  • Patent number: 9752355
    Abstract: In a vehicle door latch device, a first outside lever is pivotally mounted via a pivot shaft, and second outside lever is connected to an outside handle on an outer panel of a door via a motion-transmitting member to move toward the inside of a vehicle. Usually, turning of the second outside lever for disengaging a latch from a striker is transmitted to the first outside lever. If the second outside lever is impacted by an external force, the outer panel is deformed to move the second outside lever inward of the vehicle with respect to the first outside lever. But release turning of the second outside lever cannot be transmitted to the first outside lever. Even if the door is deformed by the external force, the door is still closed.
