Abstract:
1. A vehicle door lock device, comprising: a latch mechanism capable of maintaining a door of a vehicle in a closed state relative to a body, and adapted to be assembled to the door together with a housing; an inside open lever assembly assembled to the housing, and adapted to be rotationally driven from an initial position to an actuation position along with a door opening operation of an inside door handle which is provided on an inner side of the door; an outside open lever assembled to the housing, and adapted to be rotationally driven from an initial position to an actuation position along with a door opening operation of an outside door handle which is provided on an outer side of the door; an open link assembled tiltably to a coupling portion of the outside open lever, which is shifted along with rotation of the outside open lever, the open link comprising a link portion engageable with an engagement arm portion of a lift lever of the latch mechanism, the open link being pushed from an initial position toward the lift lever when the inside open lever assembly or the outside open lever is rotationally driven from the initial position to the actuation position; an active lever assembled to the housing, the active lever being switched to a locked position through a lock actuation of an electric actuator to bring the open link into a locked state of being unlinkable to the lift lever, and switched to an unlocked position through an unlock actuation of the electric actuator to bring the open link into an unlocked state of being linkable to the lift lever; and a child safety lock mechanism built into the inside open lever assembly, the child safety lock mechanism being configured to enable pushing force transfer from the inside open lever assembly to the open link in an unset state, and to disable the pushing force transfer in a set state, wherein the inside open lever assembly having the child safety lock mechanism comprises: wherein the active lever comprises an engagement portion set thereon, and the intermediate member comprises a pushing portion set thereon, and wherein, under a condition where the door is in an opened state and the electric actuator is inoperable, the active lever is situated at the unlocked position, and the intermediate member is situated at the unset position, when a manual operation of the door opening operation of the inside door handle and a manual operation of operating the child safety protector lever to move the intermediate member from the unset position to the set position are sequentially performed, the pushing portion of the intermediate member is engaged with the engagement portion of the active lever so that the active lever moves from the unlocked position to the locked position.
