Claims

[Scope of utility model registration request]

a base frame fixed to the side of the seat cushion; a reclining arm fixed to the side of the seat bag and pivotally supported via a planetary gear type angle adjustment mechanism; and the planet attached to the base frame or the reclining arm. A seat reclining device comprising a motor unit for driving a gear type angle adjustment mechanism, and a reclining gear provided on a rotating shaft of the planetary gear type angle adjustment mechanism, the motor unit being interlocked with a deceleration shaft of a deceleration mechanism. A seat reclining device characterized in that a drive shaft that rotates as the seat reclines is provided with a drive gear that meshes with the reclining gear.
