The present invention provides a support structure for a latch actuating lever and a lock actuating lever, which realizes a small and compact door lock apparatus for vehicles. The door lock apparatus includes a latch mechanism for maintaining a vehicle door in a closed state relative to a vehicle body, a latch actuating link coupled to the latch mechanism and actuating the latch mechanism to place the vehicle door in an openable state relative to the vehicle body, a lock actuating link for connecting or disconnecting the latch actuating link to or from the latch mechanism and thus making the latch mechanism operable or inoperable when the latch actuating link is actuated, and a base unit for supporting the latch actuating link and the lock actuating link. The base unit includes an annular support and a support shaft held in the annular support. At least one latch actuating lever, constituting the latch actuating link, is rotatablely supported on either one of the annular support and the support shaft, and at least one lock actuating lever, constituting the lock actuating link, is rotatablely supported on the other one of the annular support and the support shaft.
