PURPOSE:To enable an effective converging of air blown from an air blowing port to be carried out by a method wherein any number of louvers near a central group of a left side group of louvers and a right side group of louvers are set to be divided type louvers and at the same time remaining louvers are of integral type louvers. CONSTITUTION:Any number of louvers near a central group of a left side louver group 7B and a right side louver group 7A are set as a separated type louvers 7 comprised of fixed louvers 71 and movable louvers 72. Remaining louvers are of integral type louvers 80. Each of the movable louvers 72 of each of the divided type louvers 7 of the left and right louver groups 7B and 7A and the integral type louver 80 is cooperatively connected In the case of spot blowing, the movable louvers 72 of the divided type louvers 7 in the right side louver group 7A and the integral type louvers 80 are directed leftward, and then the movable louvers 72 in the separated type louvers 7 in the left side louver group 7B and the integral type louvers 80 are directed rightward, resulting in that air blown from both sides of the air blowing port 5 is directed toward the central part. Thus, it is possible to perform an effective convergence of air blown from the air blowing port 5. |
