1. A vehicle door lock device comprising:

  • a latch mechanism positionable in an engaged state to hold a vehicle door in a closed state relative to a vehicle body and movable to a disengaged state to permit the vehicle door to be opened;

    an inside lever operatively connected to a handle at a passenger compartment side of a vehicle door and pivotally supported about a pivot shaft supported in a housing to transmit torque;

    an inside open lever pivotally supported on the pivot shaft to receive the torque transmitted from the inside lever and thereby pivot to transmit the torque;

    an open link having a portion that receives the torque transmitted from the inside open lever, the open link moving in response to the torque transmitted from the inside open lever to transmit the torque;

    a lift lever that receives the torque transmitted from the open link to move the latch mechanism from the engaged state to the disengaged state;

    a child protector actuator;

    an intermediate lever including a guide hole in which is located the pivot shaft,a child protector lever supported pivotally about the pivot shaft and operatively connected to the child protector actuator to move in response to operation of the child protector actuator;

    a movable body movable along a portion of the inside open lever between an unset position, enabling transmission of the torque from the inside lever to be transmitted to the inside open lever, and a set position disabling said transmission of the torque;

    wherein operation of the child protector actuator to move the child protector lever in one direction causes the child protector lever to push the intermediate lever so the intermediate lever moves the movable body to the unset position allowing the torque produced by the inside lever upon operation of the handle to be transmitted to the lift lever to move the latch mechanism from the engaged state to the disengaged state; and

    wherein operation of the child protector actuator to move the child protector lever in a direction opposite the one direction causes the child protector lever to push the intermediate lever so the intermediate lever moves the movable body to the set position not allowing the torque produced by the inside lever upon operation of the handle to be transmitted to the lift lever.
