PROBLEM TO BE SOLVED: To obtain a wind direction controller in which a decrease in an air capacity for changing a wind direction of a vertical direction of air diffused from an air duct or a vibration/noise is suppressed while a stream line resistance is suppressed. SOLUTION: In the wind direction controller provided in the air duct and having a wind direction board for changing direction of the vertical direction of an air flow diffused from the duct, the wind direction board includes a plurality of substantially one row state of wind direction plates, in such a manner that a direction of the air flow is changed gradually in a target direction by controlling an inclining angle of the vertical direction of the respective wind direction plates of this one row state.
