Title: Door mechanism of automobile air conditioner

Abstract: A mix door (5) is arranged in air passages (10, 11) of an automotive air conditioning device. The mix door (5) is arranged to extend in a direction to shut an air flow blown from the upstream air passage (10) and swelled in a downstream direction with a predetermined radius of curvature. The door (5) is guided by arcuate cam grooves (19) and driven upward and downward to achieve open/close operation with the aid of a sliding mechanism (M). Compact construction, reduction in air flow resistance, smoothed handling, high sealing and high temperature controlling are achieved.
