VEHICLE SEAT RECLINING DEVICE

摘要

In the present invention, a second bracket of a vehicle seat reclining device has first and second pole restricting parts that are provided so as to respectively correspond to first and second poles and that restrict movement of the first and second poles in the diameter direction. The second pole restricting part is disposed on a positive direction side from the first pole restricting part and inward in the diameter direction. Negative-direction-side ends of the first and second pole restricting parts are respectively disposed so as to contact positive-direction-side corners of restriction parts of the first and second poles when an angle of rotation of the second bracket is a stipulated angle. The first pole restricting part allows the second pole to outward in the diameter direction.
