An arm for a wall mount and a wall mount having the arm are disclosed. The arm for a wall mount and a wall mount having the arm in accordance with an embodiment of the present invention can include: a frame; a first hinge axle rotatably coupled to one end of the frame; a first driving gear coupled to the first hinge axle; a first gear train installed in the frame so as to be engaged with the first driving gear; and a first motor configured to drive the first gear train, and the first gear train can include: a plurality of axles arranged on a same plane; and a plurality of reduction gears, each of which being rotatably coupled to one of the axles. With the present invention, it becomes possible to provide a wall mount that is slimmer but provides a greater driving force by using a smaller motor.
