A door lock device for a vehicle includes a latch mechanism having a latch rotatable to pass a half-latch state to a full-latch state, a closer mechanism capable of forcedly turning the latch from the half-latch state to the full-latch state, and an actuator for driving the closer mechanism. A casing forming a part of the latch mechanism is secured to the door so as to turnably support the latch. An extending support part extending in a direction orthogonal to a turning axis of the latch is connectedly provided in the casing. The closer mechanism is adapted to be operated on a plane orthogonal to the turning axis of the latch, and is disposed between the actuator and the extending support part so as to be aligned with the latch mechanism. Thus, it is possible to construct the door lock device to be thin so as to be easily disposed in a door.
