PROBLEM TO BE SOLVED: To prevent occurrence of incompatibility in the movement of flaps in air outlets at two locations when they are swung. SOLUTION: When flaps at two locations are selected to be swung, swinging is started right away (steps 254-258) in the case where air outlets are in a closed state. In the case where both of the flaps are in fixed positions, respectively, a synchronous position is selected being in the fixed position, and one flap is swung at a normal velocity while the other flap is swung at a velocity faster than the former (steps 260-270) so that the flaps coincide with each other at the selected synchronous position. Further, in the case where only one flap is in a fixed position, after a synchronous position is selected, swinging velocity of the flap in the fixed position is rendered faster and both flaps are permitted to coincide with each other at the synchronous position (steps 272-278, 270). |
