<p>PURPOSE: To provide a twin type damper device offering smaller construction permitting the control of three openings to be opened/closed with two baffles by improving a baffle driving mechanism. CONSTITUTION: The motor damper device has the three openings 31, 32, 33 formed in a plane T-shaped frame 4. Two rotating shafts 51, 52 extend in parallel from a position near a wheel train of the baffle driving mechanism to one side in the axial direction, and the baffles 11, 12 are connected to the rotating shafts 51, 52. The first baffle 11 puts the third opening 33 into a closed condition at one side when the first opening 31 is in an opened condition and the second baffle 12 puts the third opening 33 into a closed condition at the other side when the second opening 32 is in an opened condition.</p> |
