<p>Provided is a vehicle door lock device which more reliably prevents a door from being opened by shocks and is capable of realizing higher safety of occupants. A changeover lever (13) for a door lock device (1) comprises a lever body (20), an inertia lever (30) which is provided on the lever body (20) in such a way as to be swingable about a pivot (X1) from the initial position (P1) toward the outside of the vehicle body, and a torsion coil spring (40) which is provided between the lever body (20) and the inertia lever (30). If, in the initial position (P1), the inertia lever (30) is displaced integrally with the lever (20), then the inertia lever (30) is capable of pressing a pawl (12). The torsion coil spring (40) is provided coaxially with the pivot (X1) and holds the inertia lever (30) in the initial position (P1). The torsion coil spring (40) and a mass body (31) of the inertia lever (30) are set in such a way that that if an inertial force (F1) exceeding a preset value acts on the mass body (31), then the inertia lever (30) swings from the initial position (P1), thereby avoiding pressing the pawl (12).</p> |
