The present invention relates to a headrest moving device, and particularly, to a headrest moving device comprising: a cover having a front surface and a rear surface; a middle cover disposed in the cover and having a hollow part; a locking cover inserted in the hollow part and connected to the cover and having a tooth shape in the longitudinal direction thereof; a lock pin plate installed on the middle cover and laterally slidable thereon and provided with a lock pin inserted in the tooth shape; a lock plate installed on the middle cover and laterally slidable thereon and connected to the lock pin plate and having a through hole through which a vertical part of a stay rod passes; a return spring for returning the lock plate or the lock pin plate; and a button for laterally moving the lock plate. Thus, a longitudinal position and a vertical position of a headrest can be adjusted using one button, thereby improving user convenience. In addition, the cover is formed as a single piece to maintain a constant distance between the front surface and the rear surface, thereby minimizing a gap and a movement of the headrest moving device. In addition, the headrest moving device has a simple structure, thereby improving assembly efficiency and decreasing manufacturing costs. |
