Abstract
A front movable louver is configured for one central horizontal fin axially supported to be turnable in the horizontal direction substantially at the up-down center inside an air outlet, while an upper auxiliary horizontal fin is axially supported so as to be storable and turnable in the horizontal direction in a storing recess provided on an upper wall surface inside the air outlet, and a lower auxiliary horizontal fin axially supported to be storable and turnable in the horizontal direction in a storing recess provided on a lower wall surface inside the air outlet. The central horizontal fin is axially supported to be turnable by pivots provided to project substantially at the centers of both sides. The upper auxiliary horizontal fin and the lower auxiliary horizontal fin are axially supported to be turnable in a manner of sticking out downstream-side end portions to a passage side.
