PURPOSE:To make improvements in riding comfortableness at the inside of a car, by making a ventilation stop mode, which cuts off a state of interconnectedness between the inside and outside of the car, selectable. CONSTITUTION:A select member 30 is constituted of a cylindrical body 31 whose body outerward side end is closed by a partition plate 32 while the body side end is opened. And, at a position corresponding to an outside air intake port 8 in the front side of the cylindrical body 31, there is provided with a first opening 33 opened, while a second opening 34 is opened at a position corresponding to an inside air discharge port 10 in the rear side of the cylindrical body 31. In addition, when the first opening 33 is faced to the outside air intake port 8, the second opening 34 is opposed to the wall surface of an interconnecting duct 25 as well as when the second opening 34 is faced to the inside air discharge port 10, the first opening 33 is opposed to the wall surface of the interconnecting duct 25. A control lever 37 is engaged with each engaging projection part and thereby set to an outside air discharge mode position A, an inside air discharge mode position B and a ventilation stop mode position C, respectively, thus setting the select member 30 to a position corresponding to each mode. |
