Abstract
Abstract A wind control apparatus for an air conditioner comprises a pair of first wind-deflection plates for changing the direction of wind in a first axial direction by manual operation independent each other; a pair of second wind-deflection plates for changing the direction of wind periodically in a second axial direction with a driving means; and a phase adjusting means placed between the second wind-deflection plates and the driving means so as to change the phase of wind direction by manual operation.
