A door lock device having a sliding unit is provided to prevent erroneous opening and closing of a button cover and enable a user to easily open or close the button cover. A door lock device includes a main body(10), a button cover(20), a body slider(31), a cover slider(33), and a sliding unit(30). A button portion(13) is included in the main body. The button cover opens or closes the button portion. The body slider is coupled with the main body. The cover slider is coupled with the rear surface of the button cover so as to reciprocate in the opening and closing directions of the button cover about the body slider. The sliding unit is installed between the body slider and the cover slider and includes at least one elastic spring(35), which elastically presses the cover slide to its moving direction at a certain position when the cover slider reciprocates about the body slider.
