A mobile terminal comprising: a first frame having a first side surface; a second frame configured to slidably move in a first direction with respect to the first frame to change from a contracted state to an extended state, and including a second side surface facing the first side surface; and a link unit (310, 320) disposed between the first frame and the second frame, wherein the link unit (310, 320) includes: a first link (311, 321), one side of which is rotatably coupled to the first frame; a second link (312, 322), one side of which is rotatably coupled to the second frame; and a hinge coupled to the other side of the first link (311, 321) and the other side of the second link (312, 322), and configured to adjust an angle between the first link (311, 321) and the second link (312, 322), wherein the hinge allows the angle between the first link (311, 321) and the second link (312, 322) to vary depending on movement of the second frame, wherein the link unit includes a first link unit in which the angle between the first link and the second link is 180° when the second frame is in the extended state, and wherein the hinge includes: a first hinge shaft configured to penetrate the other side of the first link; a second hinge shaft configured to penetrate the other side of the second link; and one pair of elastic protrusions formed to protrude from the first hinge shaft and the second hinge shaft at positions spaced apart from each other by a predetermined distance, wherein the one pair of elastic protrusions are in contact with the first link and the second link when the first frame and the second frame are in the extended state. a first frame having a first side surface;
