Claims

[Scope of Claim for Utility Model Registration] An arm is attached to the frame of the seat cushion, the lower end of this arm is rotatably attached to a base plate fixed to the frame of the seat cushion, and the arm is rotatably attached to the base plate. In the seatback forward tilting mechanism of a seat reclining device which is provided with a reclining mechanism for locking the seatback and a forward tilting mechanism for tilting the seatback forward when the seatback is released, the arm is provided with arc-shaped meshing teeth, and the base plate A pinion with a concave cross-section and teeth on its outer circumferential surface that mesh with the meshing teeth is rotatably mounted via the shaft, and a spiral spring is mounted inside the shaft pinion so that the pinion always moves in one direction. A seat back-forward tilting mechanism in a seat reclining device, characterized in that the seat is biased so as to rotate.
