SLIM-TYPE AIR VENT OF VEHICLE

The present invention relates to a slim-type air vent of a vehicle. More specifically, the present invention can easily change a flow channel of air, which is discharged toward an exit through an outflow part of a duct, by means of each rotation relative to a hinge, according to a rotation state of a knob. The present invention comprises: a duct having an inflow part through which air is introduced and an outflow part enlarged compared with the inflow part and formed to communicate therewith; 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.
