The present invention relates to an air conditioner for vehicles, and more particularly, to an air conditioner for left and right independent vehicles.

In general, an air conditioner for a vehicle is an interior part of a vehicle installed for the purpose of cooling and heating the interior of a vehicle in summer or winter, or removing frost from the windshield in rainy weather or winter to secure the front and rear view of the driver. , Such an air conditioner is usually equipped with a heating device and a cooling device at the same time, so it cools, heats, or ventilates the interior of the vehicle by selectively introducing outside air or ventilation, then heating or cooling the introduced air and blowing it into the interior of the vehicle.

According to the independent structure of a blower unit, an evaporator unit, and a heater core unit, such an air conditioner is a three piece type in which the three units are independently provided, and an evaporator unit and a heater core unit are provided in an air conditioning case It can be roughly divided into a semi-center type in which the blower unit is built-in and the blower unit is provided as a separate unit, and a center mounting type in which all three units are built-in to the air conditioning case. In addition, so-called left and right independent air conditioners are also applied that allow air of different temperatures to be supplied to the driver's seat and passenger seat in the vehicle interior according to the needs of the occupant so that individual cooling and heating are performed.

At this time, a blind partitioning the inside of the air conditioning case into left and right sides is installed, and a hole through which a door shaft provided on a side surface of a door is inserted and assembled is formed through the blind and the left and right air conditioning cases. In addition, outer diameters of the door shaft are assembled to inner diameters of the blind hole, the left air conditioning case hole, and the right air conditioning case hole to support the door shaft and allow the door to rotate.

The inner diameter of the blind hole, the left air conditioning case hole, and the right air conditioning case hole and the outer diameter of the door shaft are precisely manufactured, and the gap between the blind hole, the left air conditioning case hole, and the right air conditioning case hole and the door shaft is minimized, so that precise work can be performed during assembly. will be needed

The door is assembled to the blind hole, the left air conditioning case hole, and the right air conditioning case hole and operates while rotating, and the door shaft protrudes from the outside of the air conditioning case, and a lever is assembled to the protruding door shaft.

At this time, if the lever assembled with the door shaft and the lever pin formed on the lever are out of the normal operating range of the door, the position of the lever pin is out of the range of the main lever assembly area, making it impossible to assemble the lever pin and the main lever. There is a problem in that the main lever must be assembled by adjusting the lever pin to a normal operating range (assembly range).
