Claims

[Scope of Claim for Utility Model Registration] A fixed bracket fixed to the seat cushion and provided with a substantially horizontal bearing hole facing in the left-right direction; and one end of a pivot portion rotatably supported within the bearing hole of the fixed bracket. an eccentric shaft having an eccentric shaft connected thereto; a first engaging part for holding a fixed position and a second engaging part for reclining; the eccentric shaft is rotatably fitted onto the pivot part of the eccentric shaft, and is provided on an outer peripheral edge thereof. an adjustment plate pivotally attached to the fixed bracket and configured to control the first engagement portion and the second engagement portion of the adjustment plate by appropriate operating means;
a pawl member that selectively engages and disengages from the engaging portion; a movable bracket that is fixed to the seat bag and includes a bearing hole that is pivotally fitted to the eccentric shaft portion of the eccentric shaft; External teeth or internal teeth concentric with the pivot of the eccentric shaft, and provided on the movable bracket side, concentric with the eccentric shaft of the eccentric shaft, meshing with the gear on the adjustment plate side, and having a number of teeth. has internal or external teeth that are slightly different in the number of teeth from the gear on the adjusting plate side, and the eccentric shaft, and one rotation of the eccentric shaft causes the adjusting plate and the movable bracket to mesh with each other. A seat reclining device comprising: an eccentric differential gear mechanism configured to relatively rotate by a pitch corresponding to a difference in the number of teeth between the two gears; and a rotation means for rotating the eccentric shaft.
