PROBLEM TO BE SOLVED: To realize so-called spot blow-out by transmitting the driving power of a drive motor for rotary driving a vertical deflector and turning a diffuser thereby limiting the outlet of cold air at the time of warming operation. SOLUTION: A drive motor 11 for driving a vertical deflector 8 and a diffuser 9 transmits a driving power to the vertical deflector 8 and the diffuser 9. A first rod 16 and the diffuser 9 are provided with a lost motion mechanism for preventing the diffuser 9 from being turned when the vertical deflector 8 is turned to a substantially horizontal position and turning the diffuser 9 when the vertical deflector 8 is turned to a substantially horizontal position. According to the arrangement, the vertical deflector 8 and the diffuser 9 are turned smoothly and accurately by transmitting the driving power from the drive shaft 11a of a single drive motor 11 and socalled spot blow-out is realized by limiting the outlet of cold air at the time of warming operation. |
