  "textContent": "The present invention relates to an air vent knob for a vehicle, and more particularly to enhance the operation feeling and the quality by reducing impact sound depending on the movement of a knob adjusting the wind direction of an air vent. The present invention includes an air vent wing(10) provided on the front surface of an air vent and guiding the direction of wind being discharged, where the air vent wing(10) is coupled to an assembly hole(21) of a knob(20), wherein a front stopper(11) is formed on the front surface and a knob fitting groove(12) is formed on the rear surface of the air vent wing(10) coupled to the knob(20); an assembly groove(22) is formed at the front portion inside the assembly hole(21) of the knob(20), thereby a rubber(30) is assembled thereinto; a front slide groove(31) is formed on the rubber(30) wherein the front stopper(11) of the air vent wing(10) is fitted and moved in the front slide groove(31); and a rear stopper(23) is formed on both ends of the rear portion of the knob(20), where the rear stopper(23) contacts the inner surface of both sides of the knob fitting groove (12) of the air vent wing(10). Moreover, a movement distance(I) in which the front stopper(11) of the knob(20) moves right and left along the front slide groove(31) is smaller than a movement distance(L) in which the rear stopper(23) moves right and left along the knob fitting groove(12). Therefore, the front stopper(11) is allowed to contact the wall of the front slide groove(31) of the rubber(30) in advance. Further, depending on the movement of the knob(20), in case that the front stopper(11) contacts one wall of the front slide groove(31) of the rubber(30), the rear stopper(23) is positioned being spaced apart from the one wall of the knob fitting groove(12), and in case that the rear stopper(23) contacts one wall of the knob fitting groove(12), the front stopper (11) overlaps with the wall of the front slide groove(31).",
