A mode selection unit, a blower unit and a temperature control unit are mounted on a cluster panel of a vehicle. The mode selection unit, the blower unit and the temperature control unit have a function of controlling the wind blow position, a function of controlling the wind blow rate and a function of controlling the wind blow temperature respectively, and are constituted by operating mechanisms mechanically separated from one another. Accordingly, the degree of freedom in the layout of the mode selection unit to the temperature control unit is improved so that it becomes easy to dispose them in accordance with the vehicle-side design.
