    Abstract: A door lock apparatus includes an inside lever, an opening member for switching a latch mechanism to an unlatching state by a rotation of the inside lever, a child lever translated between set and unset positions; and a bush translated together with the child lever. The bush engages with the inside lever and transmits the rotation of the inside lever to the opening member when the child lever is disposed in the unset position and is released from the engagement with the inside lever when the child lever is disposed in the set position. A movable range of the child lever and the bush is confined inside a circle centered at a rotation shaft of the inside lever and whose radius corresponds to a distance from the rotation shaft to a farthest point of the inside lever.
