VEHICLE SEAT RECLINING DEVICE

摘要

In a vehicle seat reclining device, within a predetermined angle range, the movement of every pawl in a direction towards engagement with an internal toothed portion is surely restricted to avoid any undesired contact between the pawls and the internal toothed portion. The transmitting structure 25f and 28b for transmitting and converting the rotational action of the cam 28 to the movement action of the main pawl 25 and the first restricting structure 25e and 22e for holding the main pawl 25 under disengagement state between the external toothed portion 25c and the internal toothed portion 22c are provided. The transmitting structure 26f and 28b for transmitting and converting the rotational action of the cam 28 to the movement action of the sub pawl 26 and the second restricting structure 26g and 28c for holding the sub pawl 26 under disengagement state between the external toothed portion 26c and the internal toothed portion 22c are provided. Thus, within a predetermined frontward tilting angle range, the sub pawl 26 is retained to be in disengagement state between the external toothed portion 26c of the sub pawl 26 and the internal toothed portion 22c by the transmitting structure and the second restricting structure.
