PROBLEM TO BE SOLVED: To make an open degree in fully opened state of each damper different in a case where a plurality of louver dampers including a band-like plate material are provided.SOLUTION: A band-like plate material 31 of a by-pass passage side damper 30 includes a connection part 34f arranged, in radial direction of a rotating shaft 33, to be separated by a first predetermined distance. A band-like plate material 41 of a hot air passage side damper 40 includes a connection part 44f arranged, in radial direction of a rotating shaft 43, to be separated by a second predetermined distance. The first predetermined distance is different from the second predetermined distance. An interlinking member 60 is connected to the connection part 34f of the by-pass passage side damper 30 and the connection part 44f of the hot air passage side damper 40.SELECTED DRAWING: Figure 10 |
