Abstract

A vehicle seat reclining device is provided with: a first bracket having internal teeth; a plurality of pawls each having external teeth capable of engaging with and disengaging from the internal teeth; a second bracket having a guide part that movably holds the plurality of pawls in a radial direction; and a cam mechanism which moves each of the pawls in the radial direction. Among the external teeth in each of the pawls at least one external tooth including an end tooth located at one end in the circumferential direction of the pawl is displaced inward in the radial direction with respect to a reference position corresponding to the pitch circle of the internal teeth along a center line that divides the external tooth into two parts in the circumferential direction without changing the shape of an effective engagement portion for the internal tooth and the pitch circle radius of the external tooth.
