a duct having an inflow part through which air can be introduced and an outflow part enlarged compared with the inflow part wherein the inflow part and the outflow part are in communication with each other;
a vane device for controlling the direction and the volume of the air discharged through an exit formed in the outflow part of the duct; and
a knob for providing a driving force such that the vane device rotates about a hinge, wherein the vane device comprises:
a front vane link to which a middle part of a connecting part of the knob is rotatably coupled around the hinge;
a rear vane link to which an end of the connecting part of the knob is rotatably connected to the middle part of the rear vane link around the hinge;
an upper front vane and a lower front vane wherein one end of the upper front vane and the lower front vane is rotatably coupled to the upper end and lower end of the rear vane link around the hinge, and the upper end and the lower end of the front vane link are rotatably connected around the hinge in a middle part of the upper front vane and the lower front vane;
an upper rear vane and a lower rear vane wherein one end of the upper rear vane and the lower rear vane is rotatably coupled to an end of the lower front vane and the upper front vane around the hinge; and
