Abstract
A reclining angle adjustment device for a seat includes a shaft having a concentric portion and an eccentric portion and rotatable for adjusting the reclining angle of the seat, the eccentric portion comprising an axially movable tapered ring, a gear train including an external gear and an internal gear meshing with the internal gear, the internal gear having more teeth than the external gear, a first arm having one of the external and internal gears which is rotatably fitted at its center over the concentric portion, and a second arm having the other of the external and internal gears which is rotatably fitted at its center over the tapered ring. A resilient member engages the tapered ring for normally pressing the tapered ring axially along the shaft in a direction to strengthen meshing engagement between the external and internal gears.
