Abstract: A seat reclining mechanism for adjusting the angular position of a seatback relative to a seat cushion by a planetary gear arrangement includes a rotatable shaft, a base plate, a pivotable arm, a control gear, a plurality of planetary gears, and a supporting member. Each planetary gear has a first boss portion. The supporting member has first and second circular holes for receiving therein the first boss portions of the planetary gears. The first and second circular holes are disposed on the supporting member such that a first distance between a rotational center of the supporting member and a rotational center of the first circular hole is shorter than a second distance between the rotational center of the supporting member and a rotational center of the second circular hole. The supporting member has a circular center hole. The pivotable arm has a second boss portion which is received in the circular center hole of the supporting member for mounting the supporting member on the second boss portion.
