PROBLEM TO BE SOLVED: To provide a baffle device capable of restricting occurrence of irregular sound just after a locked state between gears is released.SOLUTION: A first lock mechanism 81 in a damper device is constructed in such a way that the first arcuate outer peripheral part 686 adjacent in a peripheral direction to a default gear 682 at a driving gear 68 enters into a part where a size of the part of a plurality of teeth 694 engaged with a driving gear 68 at a sector gear 69 in its axial direction is narrowed to restrict the sector gear 69. The tooth 682c at the most first arcuate outer peripheral part 686 at the default gear 682 shows a continuous curved surface in which a curvature factor of the first tooth surface 682c1 opposite to the first arcuate outer peripheral part 686 is smaller than a curvature factor of the second tooth surface 682c2 at the first arcuate outer peripheral part 686 side and the first tooth surface 682c1 is continuous to the second tooth surface 682c2. |
