Problems solved by technology
[0006] However, the prior art damper arrangement is problematic in operation because it tends to deform and bend more than the length of the main and auxiliary joysticks
Therefore, it is difficult to accurately transmit the stroke, thereby causing the rotation operation of the damper to fail and the airtightness performance to decrease

The present invention relates to an air vent for a vehicle, provided with a damper for opening or closing the air path of a duct housing with improved operation quality and convenience. The air vent for a vehicle comprises: a duct housing (20) having an air path inside, a vane member for adjusting air discharge direction, a damper (21) for opening or closing the air path and a cover fixing boss (22) formed in an outside surface; a dial knob (30) rotationally coupled to the duct housing (20) and having a knob coupling hole (31); a damper rotation member (40) coupled to a damper (21) rotation shaft and having a pinion gear (41); a knob connector (50) having protruded coupling members (51), of which one is fitted into the knob coupling hole (31); a damper connector (60) link-connected to the knob connector (50), provided with a rack gear (61) to be engaged with the pinion gear (41), and having a guide hole (62) placed by the cover fixing boss (22) of the duct housing (20); and a guide cover (70) having an insertion part (71) fitted with the cover fixing boss (22), and a finishing part (72) coupled to the cover fixing boss (22) by a coupling member (73).
Description
technical field [0001] The present invention relates to a ventilation device for a vehicle, and more particularly, to a vehicle in which a damper for opening or closing an air path of a duct housing is operated by rotating a dial knob associated with a gear portion to improve the quality and convenience of operation ventilation device. Background technique [0002] Generally, vehicles are equipped with air conditioning equipment in which air ducts having air moving paths are provided so that air conditioners and heaters are installed in order to circulate and purify indoor air and outdoor air or maintain the temperature in the vehicle interior . [0003] A ventilation device connected to a discharge portion of the air duct is provided on a panel in a vehicle compartment for discharging air from an air conditioner or a heater toward a driver and a passenger in a desired direction so that the driver or the passenger can Enjoy a ride in moderate heat or cold. [0004] The ve...
