A door lock apparatus is provided to facilitate the opening and closing of a door by enabling a user to open the door in the same direction as a movement direction of the user. A door lock device includes a fixing unit(2100), a handle unit, a fixing cam(2310), a rotary cam(2320), and a rotary shaft(2001). The fixing unit is fixed on a door. The handle unit is coupled with the fixing unit, so that the handle unit moves straightly with respect to the fixing unit. The fixing cam is fixed on the fixing unit. The rotary cam is held by the fixing cam and coupled with the handle unit. One end of the rotation shaft is coupled with the rotary cam, while the other end thereof is coupled with a latch unit, which is embedded inside the door. The fixing cam and the rotary cam are arranged to convert the straight movement of the handle unit to a rotary movement around the rotation shaft.
