Abstract
A damper device includes a first baffle capable of opening or closing a first opening portion by turning about its axis and a second baffle capable of opening or closing a second opening portion by turning about its axis. A common drive source for driving the first baffle and the second baffle and a gear train by which the output from the drive source is transmitted to the first baffle and the second baffle are also provided. The device also includes a first rotary shaft driven by the gear train for driving the first baffle and a second rotary shaft driven by the gear train for driving the second baffle. The first rotary shaft and the second rotary shaft are arranged to be extended from the positions adjacent to each other on the gear train toward one side in an axial direction of the gear train.
