A door lock device is provided to steer a handle when a door is locked or unlocked by rotating the handle independently without an interlock with a motor. A door lock device includes a housing, a dead bolt(320), a first rotating member(350), and a second rotating member(360). A door is installed on the housing. The dead bolt is installed on the housing to lock and unlock the door. The first rotating member is coupled to the housing to rotate around the housing. The first rotating member is connected to the dead bolt so that the dead bolt is slid along a direction to indent the dead bolt into the housing together with the rotation. The second rotating member is coupled to the housing to rotate around the housing. The second rotating member is relatively rotated around the first rotating member and is connected to the dead bolt so that the dead bolt is slid along a direction to protrude toward the housing.
