AIR CONDITIONER FOR VEHICLE

摘要

Disclosed is an air conditioning device for a vehicle capable of fundamentally preventing shaking of a vent and a differential gear door while not increasing the costs for a product in a structure to adjust a degree of opening of a defrost vent and a face vent with one vent and the differential gear door. The air conditioning device for a vehicle comprises: an air conditioning case having an air inlet formed in an entrance, an air outlet formed in an exit while having a defrost vent and a face vent, and an air passage formed therein; a cooling unit and a heating unit installed in the air passage of the air conditioning case; and a vent and a differential gear door to adjust an opening of the defrost vent and the face vent. The vent and differential gear door comprises: a plate-shaped flat part rotating on a rotary shaft between the defrost vent and the face vent; and a baffle protruding from one surface of the flat part to press the vent and the differential gear door in a specific direction of a rotational radius using discharge air passing therethrough. Therefore, the present invention prevents shaking of the vent and the differential gear door in a vent and a differential gear mode by maintaining a state where the vent and the differential gear door is always pressed in the specific direction; thereby preventing noise due to the shaking of the vent and the differential gear door. Moreover, the present invention prevents an increase in manufacturing costs by effectively preventing shaking without a shaking prevention unit.
