PROBLEM TO BE SOLVED: To enable a wideness of a buffle to be sufficiently utilized, cause the buffle to be positively closed, concurrently an icing to be hardly produced and further to cause a stable and accurate driving of the buffle to be carried out. SOLUTION: This motor-driven type damper device is comprised of a motor, a buffle 4 for opening or closing an opening 3 through which fluid passes, a transmitting means 13 for transmitting a driving operation of the motor to the buffle 4 and a biasing means 15 for abutting the buffle 4 against the opening 3. Then, the motor, is installed at a side of the buffle 4 and when the buffle 4 is set to its closed position, the buffle 4 may form a clearance (h) where it is displaced in an opening or a closing direction and the buffle 4 is closely contacted to the opening 3 by a biasing means 15. |
