1. A door lock apparatus for a vehicle, comprising:
- a latch mechanism retaining a vehicle door in a closed state relative to a vehicle body;
an open operation lever adapted to operate by operation of an inside door handle provided at the vehicle door;
an open lever operatively connected to the open operation lever;
a locking lever being switchable between an unlocked position and a locked position;
a link operation lever operatively connected to the locking lever by way of a biasing member;
a link member arranged between the latch mechanism and the open lever and operatively connected to the link operation lever, the link member being able to transmit an operation of the open lever to the latch mechanism when the locking lever is in the unlocked position, the latch mechanism being operated to bring the vehicle door to be in an open ready state relative to the vehicle body, the link member being unable to transmit the operation of the open lever to the latch mechanism when the locking lever is in the locked position;
a lever member operatively connected to the open lever through a block member and operatively connected to the locking lever, the lever member moving the locking lever from the locked position to the unlocked position by operation of the open lever;
the block member supported at the open lever to transmit an operation of the open operation lever to the open lever and the lever member;
a rotatable child lock lever positionable in a child lock unset position at which operation of the open operation lever is transmittable to the open lever by way of the block member and positionable in a child lock set position at which operation of the open operation lever is not transmittable to the open lever by way of the block member; and
wherein the lever member is switchable between a locked position and an unlocked position in association with the locking lever, the lever member including an extending portion extending towards the block member, the block member including a push surface able to press the extending portion, and the lever member is switched from the locked position to the unlocked position by a transmission of the operation of the open operation lever to the lever member via the push surface and the extending portion.
