PURPOSE: A device for driving an antenna is provided to prevent a contact pressure between a rotation contact unit and the antenna from getting excessively bigger or smaller, thereby considerably reducing possibility of product failure as smoothly driving the antenna. CONSTITUTION: A rotation driver(110) has a rotation axis(112). A rotation contact unit(130) slopes toward the rotation axis(112), and transfers an antenna(10) in length direction when being rotated by a rotational force of the rotation driver(110), in connection with an external side of the antenna(10) by being crossed with the antenna(10). Elastic couplers(170) installed between the rotation driver(110) and the rotation contact unit(130) transfers the rotational force of the rotation driver(110) to the rotation contact unit(130), and supplies an elastic force to the rotation contact unit(130) as allowing the rotation contact unit(130) to be rotated on the rotation axis(112) in sloped state. |
