PROBLEM TO BE SOLVED: To provide a small-sized seat recliner structure capable of obtaining large locking strength. SOLUTION: A seat cushion side locking plate 38 is attached to a seat cushion non-rotatably around a rotary axis and movably in the rotary axis direction. A seat back side locking plate 62 is fixed to the seat back. On the surfaces where the seat cushion side locking plate 38 faces the seat back side locking plate 62, teeth 70 and 72 are formed. Normally, by the engagement of the teeth 70 and 72, the seat back side locking plate 62 is non-rotatably locked to the seat cushion side locking plate 38. Then, by an operation, the seat cushion side locking plate 38 is moved in an axial direction and separated from the seat back side locking plate 62, the engagement of the teeth 70 and 72 is released and the seat back is rotated. The locking surface of the teeth 70 and 72 is constituted within a plane passing through a center line C and the locking strength is enlarged.
