摘要： A damper apparatus possible to suppress abnormal sounds immediately after the locking of gears has been released is provided. In a first lock mechanism of the damper apparatus, a first arcuate outer-peripheral part peripherally adjacent to a teeth-missing gear in a drive gear enters a portion of a plurality of teeth in which some teeth are narrowed in the axial direction to restrain a sector gear, the teeth being meshed with the drive gear in the sector gear. In the tooth nearest to the first arcuate outer-peripheral part in the teeth-missing gear, the curvature of a first tooth flank on the side opposite the first arcuate outer-peripheral part is less than the curvature of a second tooth flank on the first arcuate outer peripheral part side, and the tooth has a curved surface continuous from the first tooth flank to the second tooth flank.
