Abstract
A seat reclining device includes a first bracket, a second bracket, a cam, and pawls moved in a radial direction and engaged with the second bracket. The pawls include outer teeth engageable with the second bracket. The second bracket includes an outer circumferential wall including inner teeth engaged with the outer teeth, and an inner circumferential portion. At least one of the pawls includes a first block and a second block shifted in an axial direction from the first block. The second block is formed integrally with the first block. The first block includes the outer teeth and a cam surface that contacts the cam. The second block includes a restriction surface that contacts the inner circumferential portion when the pawl moves toward the outer side. The cam surface and the restriction surface have the same planar structure.
