A seat recliner for vehicles is disclosed. The seat recliner of the present invention includes a sector gear (110), which has a seat back coupling part (111), and a holder (120), which is rotatably coupled to the sector gear (110) and has a seat cushion coupling part (121). The seat recliner further includes a cam (130), which is rotated by a shaft (40), a lock gear (140), which releasably locks the sector gear (110) to the holder, and a return spring (160), which elastically biases the cam to its original position. The seat back coupling part includes a main body (111a), which protrudes from the sector gear, and coupling teeth (111b), which are provided on the main body at predetermined intervals. Thereby, in the present invention, even if a large force is applied to the seat back, the seat recliner can stably support the seat back. |
