摘要 A seat reclining apparatus for a vehicle, includes a first arm (11), a second arm (12) rotatably supported by the first arm, a pawl (31A) including external teeth (44) engageable with internal teeth (23), a cam portion (45) and plural pawl-side cam surfaces (50a, 50b, 50c) arranged at the cam portion, a cam (32) including a cam surface (55) engaging with the cam portion formed at the pawl, and a biasing member biasing the cam to rotate and causing the cam surface to press the cam portion in a radial direction. The plural pawl-side cam surfaces or the cam surface is configured in a manner that the plural pawl-side cam surfaces and the cam surface are in contact with each other when the external teeth and the internal teeth are in an engaged state and in a manner that clearances generated between each of the plural pawl-side cam surfaces and the cam surface in the radial direction are all uniform.
