Abstract: The present disclosure relates to a damper dial for a vehicle air vent and prevents a manipulation force from increasing even when a dial fixture in which a dial body is rotatably installed is deformed by an impact generated while a vehicle is being operated such that the inner wall surfaces of the dial fixture are displaced toward the dial body. The damper dial includes: a dial body (100) in which a hinge hole (120) is formed to penetrate a center portion of the dial body and a dial (110) is formed on a front surface portion of the dial body; a first dial bush (200) in which a hinge protrusion (210) protrudes from one side surface of the first dial bush so as to penetrate through and be inserted into the hinge hole (120) formed in the dial body (100) and a support pin (211) extends from a distal end portion of the hinge protrusion (210); a second dial bush (300) in which an insertion groove (320) is inwardly formed on one surface of the second dial bush so that the support pin (211) of the first dial bush (200) is inserted into the insertion groove (320) and an annular groove (310) is formed outside the insertion groove (320); an O-ring (400) installed so that an outer surface of the O-ring makes contact with one side surface of the dial body (100) in a state where the O-ring (400) is seated on the second dial bush (300); and a dial fixture (500) in which an assembling hole (510) is perforated and formed such that the first dial bush (200) and the second dial bush (300) fixed to each of both left and right sides of the dial body (100) are assembled to the dial fixture while making contact with inner wall surfaces of the dial fixture.

Abstract: A dual damper device of a vehicle air vent includes a duct housing having a partition wall for dividing an air path, an introduction part and a discharge part, which are bent to be inclined; a pair of dampers rotationally mounted on the air path in the introduction part; a dial knob rotationally provided to the discharge part; a dial bush having a knob fitting part and an elongated guide groove; a pair of damper bushes vertically coupled to the dampers; and a bush link. The duct housing further includes a dial support member rotationally coupled to the dial knob and damper holding stepped protrusions provided to the partition wall and the introduction part.
