A seat reclining mechanism for a vehicle seat, comprising:a first housing having a guide groove, the guide groove having first and second guide surfaces; a second housing having a toothed portion; and a pawl slidably received in the guide groove, the awl having first and second side surfaces that respectively correspond to the first and second guide surfaces of the guide groove, wherein the pawl engages the toothed portion of the second housing by sliding from its non-engaging position to its engaging position along the guide groove, thereby preventing the second housing from rotating relative to the first housing, wherein the first side surface of the pawl and the first guide surface of the guide groove are arranged and constructed such that a clearance defined therebetween is changed so as to have an optimal width when the pawl is shifted from the non-engaging position to the engaging position.
