Claims

[Scope of Claim for Utility Model Registration] (1) In a seat reclining device that has a return spring that constantly biases a seat back that can be rotated forward and backward, the return spring moves forward from the upright position of the seat back. A seat reclining device characterized by having a configuration in which no rotation biasing force is applied. (2) The seat reclining device according to claim 1, characterized in that the lower hinge bracket is provided with a stopper that restricts the force of the return spring from rotating forward from the upright position of the seat back.
