Air mix damper device and vehicle air conditioner

摘要

The invention provides an air mixing damper apparatus and an air conditioning apparatus for vehicles where the temperature of discharged air can be changed linearly with respect to the operation of an actuator lever. A rotation speed adjustment mechanism is disposed between a plate door type air mixing damper 43A for opening and closing an air introducing face 42a of a heater core 42, and a rotation type lever 48 for an actuator 47 driving the air mixing damper 43A, for adjusting the rotation speed at an initial opening stage X and a final opening stage Z of the air mixing damper 43A, to a speed lower than at an intermediate opening stage Y.
