A lead screw structure comprises a screw shaft having a thread on an outer circumferential surface thereof, a nut unit coupled to the screw shaft such that and a thread formed on an inner circumferential surface of the nut unit is engaged with the thread of the screw shaft, and a first elastic member disposed on a portion of the nut portion, in a direction of the screw shaft, to provide an elastic force to the nut portion in the screw shaft, thereby compensating for a gap between the thread of the outer circumferential surface of the screw shaft and the thread of the inner circumferential surface of the nut unit.
