PROBLEM TO BE SOLVED: To reduce the length of a whole case and reduce the operating force of a wind volume control means. SOLUTION: This wind direction controller includes a hollow case 7 communicated with a duct 5 and open 10 to the inside of a room 6, a housing 8 pivotally supported inside the case in a rotatable manner for changing the flow angle of air A flowing into the room via a duct 5 and a control means for controlling the rotation of the housing 8. The control means allows the movement of the housing 8 so that the peripheral wall 8a of the housing 8 can be put in contact with the opening 10 of the case 7 to prevent the flow of the air A in the case 7.
