Abstract

In an air conditioning apparatus for a vehicle having a casing which has an air suction opening and an air blowing opening at opposite ends of the casing. Contained within the casing are a fan for feeding air, an evaporator, an air mixing damper, and a heater, disposed in order from an upstream end of the casing. The air mixing damper is disposed in a position closely adjacent to an upstream side of the heater. The damper is constructed so as to be movable between a position for fully closing a front side of the heater and another position for fully closing a by-pass air flow passage provided for by-passing the heater. Provided at one side of the damper, is a rack extending along a moving direction of the damper, and a driving shaft, which is rotatably supported in the casing and carries a pinion which is engaged with the rack.
