PROBLEM TO BE SOLVED: To provide a wind direction control mechanism for an air outlet for actualizing the smooth diffusion of supply air into a room while preventing the generation of a draft downward from the air outlet provided in the ceiling of the room into which air is supplied along a wall or window glass, and to provide a ductless ventilating system using the same. SOLUTION: The mechanism comprises a fixed plate 28 fixed to the ceiling 11a for blocking a central portion of an opening 27 of a polygonal shape formed in the ceiling 11 of the room into which air is supplied, and a movable member 34 provided on the fixed plate movably in the horizontal direction and having an outer peripheral edge in a similar shape smaller than the polygonal shape. The air outlet 35 is formed between the opening and the outer peripheral edge of the movable member. The fixed plate has a guide groove which has a first grooved portion 38 extending toward one side 27a of the opening and a second grooved portion 40 extending toward the other side adjacent to one side 27a in communication with the first grooved portion. The movable member has a protruded portion 38 inserted through the guide groove. COPYRIGHT: (C)2008,JPO&INPIT
