WIND DIRECTION ADJUSTMENT DEVICE

A wind direction adjustment device includes a plurality of fins supported at top and bottom end sides in a case; a link mechanism associating the fins; a horizontal-fin supported at right and left end sides at second support portions in the case; and a knob supported movably to front and back and to right and left relative to the horizontal fin. The wind direction adjustment device adjustably switches between a parallel air-blowing mode wherein the fins become approximately parallel to one another and a dispersive air-blowing mode wherein two or more of the fins are turned in opposite directions through the knob. The parallel air-blowing mode is switched to the dispersive air-blowing mode by operating the knob forward or backward in an air-blowing direction, wherein by operating the knob to a right or left side, some fins turn in an approximately same direction to switch a dispersive air-blowing direction.
