Air conditioner for vehicle

摘要

The present invention relates to an air conditioner for a vehicle that includes: a mode door (130) having a thin plate member (150), which slidably operates inside an air-conditioning case (110) to control the degree of opening of a defrost vent (112), a face vent and floor vents, and a gear shaft, which engages with the thin plate member for operating the thin plate member (150); and constant discharging means (119) disposed at a rail portion of the thin plate member (150) and at a guide part of an air-conditioning case (110) overlapped with the rail portion (155), so that air of a fixed quantity is discharged to side vents of the face vent (113), thereby providing a simple structure and reducing manufacturing costs because the gear holes of the rail portion (155) and the cut portions of the guide portion, which are the constant discharging means, can be used as a constant discharge structure without needing additional structure to constantly discharge air toward the side vent.
