<p>PROBLEM TO BE SOLVED: To provide a damper device capable of being miniaturized even when influence of backlash between gears in a driving part is restrained by a spring.SOLUTION: In a damper device 1, a baffle 4 takes an open posture, a close posture and an intermediate posture with a driving part 6 having a stepping motor and a reduction gear train. The baffle 4 is energized by a torsion coil spring 9. A winding part 90 of the torsion coil spring 9 is arranged around a second shaft part 462 having an outside diameter smaller than a first shaft part 461 of a shaft part 46 coaxial with a rotation center axis L, and one end 91 is abutted to a frame 2, and the other end 97 is abutted to a surface on a side opposite from an opening 210 of the baffle 4. An outside diameter of the winding part 90 is smaller than that of the first shaft part 461.</p> |
