  • Patent number: 9410345
    Abstract: A switching mechanism of vehicle door lock device includes a pivotable first lever and a second lever that pivotably acts on a pawl. An inertial lever is provided on the first lever and is pivotable about an axis (X3) from an initial position when an inertial force is applied thereto. A transmitting portion is provided on the second lever and transmits the pivotal movement of the first lever to the second lever when the inertial lever is disposed in its initial position. In contrast, the transmitting portion does not transmit the pivotal movement of the first lever to the second lever when the inertial lever has been pivoted away from its initial position. A first axial center of pivotal movement of the first lever and a second axial center of pivotal movement of the second lever are coaxial axial centers of pivotal movement (X1).
