Abstract: An adjustment knob for rotating a horizontal vane and a vertical vane of a motor vehicle air vent is provided. The adjustment knob includes a knob body and a vane rotating portion. The knob body is coupled to the horizontal vane so as to be movable in a horizontal direction. An inserting gap, into which the horizontal vane is inserted in a frontward direction, and a receiving gap, which is enlarged from the inserting gap, are penetrated through the knob body in the horizontal direction. The vane rotating portion rotates the vertical vane by a movement of the knob body. The vane rotating portion is fixed to a rear end of the knob body below the inserting gap, and is connected to the vertical vane. The knob body is coupled to the horizontal vane such that a front end of the horizontal vane is positioned in the receiving gap and the vane rotating portion is adjacent to a rear end of the horizontal vane.
