1. An air conditioner for a vehicle having a passenger compartment, comprising:

  • a first duct forming a first air passage for introducing air toward a first air conditioning zone in said passenger compartment;

    a second duct for forming a second air passage for introducing air toward a second air conditioning zone in said passenger compartment;

    first temperature adjusting means for adjusting a temperature of air in said first air passage according to a position thereof;

    second temperature adjusting means for adjusting a temperature of air in said second air passage according to a position thereof, independently of said first temperature adjusting means;

    temperature controlling means for controlling said first temperature adjusting means so as to set a deviation between target positions and actual positions of said first temperature adjusting means within a range from a negative predetermined value to a positive predetermined value and for controlling said second temperature adjusting means so as to set a deviation between target positions and actual positions of said second temperature adjusting means within a range from a negative predetermined value to a positive predetermined value; and

    shifting means for shifting one of said target positions of said first and second temperature adjusting means in a deviated direction where an actual position of the other temperature adjusting means is deviated from said target position of the other temperature adjusting means such that a relative deviated amount in the respective temperature adjusting means becomes smaller than the range from the negative predetermined value to the positive predetermined value.
