PURPOSE: An air flow direction control apparatus is provided to achieve a uniform air conditioning effect by preventing diffusion of air flow in a vertical direction. CONSTITUTION: An air flow direction control apparatus comprises left and right vanes(1') connected to a connection portion(3), and controls the direction of air flow by being rotated in left and right directions centering from a rotation center(2). The left and right vanes have air flow guide blades(7) attached to the upper and lower side surfaces of the left and right vanes, respectively, so as to prevent a vertical diffusion of the air flow being guided by the apparatus.
