In order to quickly condition a room by blowing conditioned air from an air blowing opening over a wide range, a fixed air blowing portion 75 is disposed at a central portion in a raised portion 740 in which a part of a decorative panel 70 is raised toward the air conditioning room. Movable air blowing portions 77 are disposed on both sides thereof. The movable air blowing portion 77 is rotatable within a predetermined angle range around an axis orthogonal to the panel surface of the decorative panel 70 or to the ceiling surface, while air blowing openings 754 and 783 are formed on each side surface of the fixed air blowing portion 75 and the movable air blowing portion 77. As a result, the conditioned air is blown out in a wide range in the horizontal direction from the air blowing opening 783 as the movable air blowing portion 77 rotates.
