A vehicle door lock device is provided. The vehicle door lock device includes a latch mechanism, an inside lever, an inside open lever, a bushing, a child protector lever, and an intermediate lever. The inside lever is operable from a passenger compartment side of a vehicle and supported pivotally about a support pin arranged in the vehicle door. The intermediate lever includes a guide hole, which receives the support pin. When pushed by the child protector lever as the child protector lever pivots, the intermediate lever pushes the bushing while moving along the guide hole relative to the support pin and thereby moves the bushing to a position between the unset position and the set position.
