Abstract
Disclosed is a reclining mechanism comprising: a first plate fixed to a seat back; a second plate fixed to a seat cushion; a plurality of planetary gears in meshing engagement with internal gears of the first and second plates; a sun gear in meshing engagement with the planetary gears; and a holding member rotatably holding the planetary gears. An inclined wall portion of the holding member, and an inner peripheral wall of a concave portion of the second plate, define therebetween a wedge-shaped space in which a restriction member is displaceably disposed. The inclined wall portion of the holding member is formed such that a width of the wedge-shaped space is gradually narrowed toward a counter direction opposite to a specific direction along which the first plate is urged to be rotated according to a force applied to the seat back in a rearward tilting direction.
