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 43 A for opening and closing an air introducing face 42 a of a heater core 42 , and a rotation type lever 48 for an actuator 47 driving the air mixing damper 43 A, for adjusting the rotation speed at an initial opening stage X and a final opening stage Z of the air mixing damper 43 A, to a speed lower than at an intermediate opening stage Y.

1. An air mixing damper apparatus comprising:a mechanism provided between a plate door type air mixing damper for opening and closing an air introducing face of a heater core, and a rotation type lever of an actuator for driving the air mixing damper, the mechanism for adjusting rotational speed of the air mixing damper to linearly change the temperature of discharged air with respect to the operation of the lever of the actuator, said mechanism for adjusting rotational speed comprising:a cam connected to the air mixing damper and a pin provided on the lever of the actuator for engaging with said cam, said cam incorporating a guide path for guiding the pin of the lever of the actuator, and the guide path has a first guide path for effecting control at an initial opening stage of the air mixing damper, a second guide in path for effecting control at an intermediate opening stage of the air mixing damper, and a third guide path for effecting control at a final opening stage of the air mixing damper, first guide path formed in a direction gradually separating outward with respect to a turning path of the pin of the lever of the actuator, in a fully closed position of the air mixing damper, and said third guide path formed in a direction gradually separating outward with respect to the turning path of the pin of the lever of the actuator, in a fully open position of the air mixing damper; andurging means for urging the pin of the lever of the actuator into the first guide path at least at an initial opening stage of the air mixing damper, and for urging the pin of the lever of the actuator into the third guide path at least at a final opening stage of the air mixing damper. 2. An air conditioning apparatus for vehicles having an air conditioning unit provided with:an inside air/outside air box incorporating an inside/outside air switching damper configured to open an outside air introducing inlet and an inside air introducing inlet to selectively switch introduced air to one of inside air and outside air,a blower unit comprising a blower fan configured to blow the introduced air,a cooler unit comprising an evaporator configured to exchange heat between a refrigerant and said introduced air passing therethrough, anda heater unit comprising a heater core disposed inside a heater unit case and configured to heat the introduced air passing therein, the air mixing damper apparatus according to claim 1 the air mixing damper apparatus configured to adjust a flow quantity of said introduced air passing through said heater core, and a plurality of air outlets opening from said heater unit case and respectively provided with dampers. 3. An air mixing damper apparatus comprising:a mechanism provided between a plate door type air mixing damper for opening and closing an air introducing face of a heater core, and a rotation type lever of an actuator for driving the air mixining damper, the mechanism for adjusting rotational speed at an initial opening stage and a final opening stage of the air mixing damper, to a speed lower than at an intermediate opening stage, said mechanism for adjusting rotational speed comprising:a cam connected to the air mixing damper and a pin provided on the lever of the actuator for engaging with said cam said cam incorporating a guide path for guiding the pin of the lever of the actuator, and the guide path has a first guide path for effecting control at the initial opening stage of the air mixing damper, a second guide path for effecting control at the intermediate opening stage of the air mixing damper, and a third guide path for effecting control at the final opening stage of the air mixing damper, said first guide path formed in a direction gradually separating outward with respect to a turning path of the pin of the lever of the actuator, in a fully closed position of the air mixing damper, and said third guide path formed in a direction gradually separating outward with respect to the turning path of the pin of the lever of the actuator, in a fully open position of the air mixing damper; andurging means for urging the pin of the lever of the actuator into the first guide path at least at an initial opening stage of the air mixing damper, and for urging the pin of the lever of the actuator into the third guide path at least at a final opening stage of the air mixing damper. 4. The air mixing damper apparatus according to claim 3 wherein a range of opening of the air mixing damper is from fully closed to about 15 degrees in said initial opening stage and a range of opening of the air mixing damper is from 20 degrees from fully open to fully open in the final opening stage. 5. An air conditioning apparatus for vehicles having an air conditioning unit provided with:an inside air/outside air box incorporating an inside/outside air switching damper configured to open an outside air introducing inlet and an inside air introducing inlet to selectively switch introduced air to one of inside air and outside air,a blower unit comprising a blower fan configured to blow the introduced air,a cooler unit comprising an evaporator configured to exchange heat between a refrigerant and said introduced air passing therethrough, anda heater unit comprising a heater core disposed inside a heater unit case and configured to heat the introduced air passing therein, the air mixing damper apparatus according to claim 3 the air mixing damper apparatus configured to adjust the flow quantity of said introduced air passing through said heaters core, and a plurality of air outlets opening from said heater unit case and respectively provided with dampers.
