Air vent for a vehicle

An air vent for a vehicle, comprising:

• a duct housing (10) having an air flow path formed therein and a air discharge hole (11) provided at the front side thereof;
• a damper (15) positioned in the air flow path at the rear side of the duct housing (10);
• a plurality of front vanes (20) arranged on spacers, which are provided to an upper end and a lower end in the front portion of the duct housing (10), so as to rotate in the right and left directions;
• a plurality of rear vanes (30) positioned in front of the front vanes (20) and arranged on spacers, which are provided on a right side and a left side in the duct housing (10), so as to rotate in the vertical direction, and having interlocking shafts (32) further provided at the rear portions of hinge shafts (31) at one side of the rear vanes;
• a vane knob (35) coupled to one of the rear vanes (30) and fitted with one of the front vanes (20) at an adjustment bar provided at the front end of the inside thereof, so as to rotate the rear vanes (30) in the right and left directions and rotate the front vanes (20) in the vertical direction;
• a rear vane joint link (40) having rear vane link bars (41) for respectively connecting the interlocking shafts (32) of the plurality of rear vanes (3) so as to enable joint motion, and a rear vane operation bar (42) further assembled into the rear vane link bars (41) in such a manner that one end of the rear vane operation bar (42) is coupled by a pin to the rear vane interlocking shaft (32) at a position in the center of the rear vane link bars (41) and the other end thereof is provided with a rear vane movement pin (42a);
• a damper joint link (50) having a rotation arm (51), of which one end is assembled into a side surface at the rear portion of the duct housing (10) so as to be coupled to the damper (15) and the other end is assembled into a dial link bar (52), which is positioned in a forward discharge hole direction at the outside of the duct housing (10) and has a damper rotation pin (52a) at a front end thereof;
• and
• a dial assembly (60) having a dial support member (61) coupled to a side surface at the front portion of the duct housing (10), a dial knob (62) rotatably provided to the inside of the dial support member (61), and a rear vane cam hole (64) and a damper cam hole (65) formed next to each other in the rear surface of the dial knob (62) such that one end of the dial link bar (52) moves along the damper cam hole (65) and the one end of the rear vane operation bar (42), which is connected to the rear vane link bar (41), is coupled to the rear vane cam hole (64), thereby moving the dial link bar (52) and the rear vane link bar (41) by the rotation of the dial knob (62) in the horizontal direction.
