While the air is guided in a direction that is almost horizontal, at the longitudinal ends of the air outlet (16) where the blowing flow velocity is relatively slow, a part of the conditioned air is supplied to both ends of the horizontal blade (18). The air blows downward from the center through the opening (18c). For this reason, the airflow flowing toward the negative pressure side of the horizontal blade (18) increases at both ends of the horizontal blade (18), so that the air-conditioned air having a low initial velocity blown out at both ends of the air outlet (16). The flow rate along the ceiling decreases. Also, during the heating operation, the conditioned air is blown downward from the entire air outlet (16) into the room by adjusting the horizontal blades (18) downward.
