A door lock apparatus for a vehicle, comprising a lever mechanism section (A2c) adaptively configured to be connected, via a rod, to a key cylinder disposed in an outside handle of a vehicle door, and adaptively configured such that an active lever of a lock mechanism performs a locking operation or an unlocking operation in response to a turning operation of the key cylinder, the lever mechanism section (A2c) comprises an outside locking lever adaptively linked to the rod and to the active lever and rotatably mounted to a housing mounted within the door; the outside locking lever comprises: a hub portion rotatably mounted to the housing and having a connection subportion to which an inner end portion of the rod is adaptively connected in such a manner as to be able to transmit torque in a vehicle interior-exterior direction; an arm portion extending radially outward from the hub portion and linked to the active lever; a hub-side engagement subportion (41a2) provided on the hub portion and engaged in the vehicle interior-exterior direction with a first support portion provided on the housing; an arm-side engagement subportion (41b2) provided on the arm portion and engaged in the vehicle interior-exterior direction with a second support portion provided on the housing; and a fragile portion provided between the hub-side engagement subportion (41a2) and the arm-side engagement subportion (41b2) and being breakable with a force of a predetermined value or greater; when the rod is pushed inward with respect to the vehicle interior-exterior direction, and an associated pushing force is imposed on the outside locking lever, the pushing force is received by the first support portion and the second support portion of the housing; and a space is provided in the housing for allowing movement of the hub portion in the vehicle interior-exterior direction, while an associated movement of the arm portion (41 b) is restricted by the second support portion, so as to allow breakage at the fragile portion due to said pushing force. the lever mechanism section (A2c) comprises an outside locking lever adaptively linked to the rod and to the active lever and rotatably mounted to a housing mounted within the door;
