Abstract: The present invention relates to a roof air vent for a vehicle and, more specifically, to a roof air vent which permits a passenger onboard the vehicle to conveniently control, as needed, a wide distribution of air being supplied into the vehicle through the roof air vent. The roof air vent comprises: an outer bezel (110) which has an air flow hole (111) penetrated in the central portion thereof and has a mounting hole (112) penetrated in an outer region of the air flow hole (111); a spacer ring (160) which is mounted in the air flow hole (111); a plurality of vanes (140), each of which has both lateral ends rotatably coupled to a hinge shaft (161) formed on the inner surface of the spacer ring (160); a link (150) which connects one vane (140) to another vane (140) so as to allow the plurality of vanes (140) to simultaneously rotate about the hinge shaft (161); an inner bezel (120) which is mounted so as to be able to vertically enter and exit the mounting hole (112) formed in the outer region of the air flow hole (111); and a cover (170) which is mounted on the upper part of the outer bezel (110) so as to prevent the inner bezel (120) and the spacer ring (160) from being separated from the air flow hole (111) and the mounting hole (112), respectively.
