BLOWOFF MODE DOOR FOR VEHICLE AIR CONDITIONER AND VEHICLE AIR CONDITIONER EMPLOYING IT

摘要

A blowoff mode door for vehicle air conditioner in which independent temperature regulation performance can be enhanced by minimizing the clearance between a mode door and a partition panel and enhancing rigidity of the mode door thereby suppressing leakage of temperature regulated air. A vehicle air conditioner employing it is also provided. The blowoff mode door applied to a vehicle air conditioner of independent temperature regulation system comprises a rotating shaft (40) having a predetermined length, and a pair of right and left plate-like doors (42B, 42A) formed integrally with the rotating shaft (40) with an air gap (41) for avoiding interference with the partition panel (22). The rotating shaft (40) has a rib (43), in its cross-section, extending in the direction parallel with and/or perpendicular to the plate surface of the plate-like doors (42B, 42A) around the shaft, and circular ribs (44) for mutually coupling the ribs (43) are provided at a plurality of positions at a predetermined pitch between the pair of right and left plate-like doors (42B, 42A) of the rotating shaft (40) having that cross-section.
