An automobile seat angle adjuster comprises a gear cover (1), a gear bowl (2), a small gear sheet drive mechanism (4) and an edge covering ring (5). The automobile seat angle adjuster is characterized in that each small gear sheet (3) is of a two-level thickness stepped structure in the thickness direction, grooves (34) are formed due to the thickness level differences, and hanging lug holes (32) are formed in the thin walls of the small gear sheets (3); a cam plate (41) is further provided with protruding parts extending radially and hanging lugs (412) are arranged on the protruding parts; in a locking state, stop protrusions (413) of the cam plate abut against two bottom edges (33) of the small gear sheets; in the unlocking stroke, the hanging lugs (412) move along the hole walls in the hanging lug holes (32) to drive the small gear sheets to be displaced in the direction of a center shaft (42), and teeth of the small gear sheets are separated from a gear ring of the gear bowl. By the adoption of the automobile seat angle adjuster, the purposes of continuous uniformity, reliability and the like of motions of the small gear sheets are achieved, unlocking operation is convenient and stable, gaps of a product structure are small, the size is small, assembling operation is convenient, and production cost is low.
