PROBLEM TO BE SOLVED: To improve designability of a structure serving as an incorporation destination, by controlling a wind direction by a simple structure without providing an air outlet with a fin for controlling the wind direction.SOLUTION: An air outlet part (11) provided with an air outlet (22) has a double cylinder structure that comprises inner and outer cylindrical bodies (13) and (15). Air flowing inward from one end of the outer cylindrical body (15) is divided into an air flow directed toward the air outlet (22) from its inflow side and an air flow directed toward the air outlet (22) from the side opposite to its inflow side. A flow rate between both the air flows can be adjusted by a slide motion of the inner cylindrical body (13). |
