Claim 0:
1. An air vent for a vehicle, the air vent comprising:
a housing having formed therein a flow path in which air flows; and
a plurality of wing members rotatably engaged to the housing to open and close the flow path and having a gap formed between adjacent wing members of the plurality of wing members when the plurality of wing members rotate in a direction to close the flow path,
wherein the gap changes a path in which the air flows to minimize inflow of the air, and forms a pressure reducing section to reduce a flow rate,
wherein each wing member of the plurality of wing members comprises:
a protrusion portion formed to protrude outwardly from a surface;
a first flange portion formed to extend outwardly from the protrusion portion;
a groove portion formed insertedly in an opposite surface and accommodating a protrusion portion of an adjacent wing member of the plurality of wing members to form the gap; and
a second flange portion continuing from the groove portion on the opposite surface and formed protruding to face a first flange portion of the adjacent wing member of the plurality of wing members,

wherein the gap comprises:
an inflow path formed by the first flange portion of each wing member of the plurality of wing members and a second flange portion of the adjacent wing member of the plurality of wing members;
a curved flow path formed by the protrusion portion of each wing member of the plurality of wing members and a groove portion of the adjacent wing member of the plurality of wing members; and
a discharge flow path connected to the curved flow path and formed by each wing member of the plurality of wing members and the adjacent wing member of the plurality of wing members to allow air to be discharged therethrough,

wherein an outer circumferential surface of the first flange portion and an outer circumferential surface of the second flange portion are formed curvedly to extend to each other in a streamlined shape and guide the air in a direction inclined with respect to the flow direction of the air flowing in the flow path.
