A seat recliner comprises an inner toothed plate (2) having an inner ring gear (21), an outer toothed plate (3) having an outer ring gear, an eccentric wheel (4) and a wedge-shaped block (6). A shaft shoulder (22) is provided in the center of the inner toothed plate (2), and an axis central hole (32) is provided in the center of the outer toothed plate (3). The outer ring gear engages with the inner ring gear (21), and a radially eccentric area is formed between the shaft shoulder (22) and the axis central hole (32). The eccentric wheel (4) is disposed in the radially eccentric area, and appears entirely in the shape of an eccentric ring, and a planetary gear transmission mechanism with small difference between the number of teeth is constituted by the eccentric wheel (4), the inner toothed plate (2) and the outer toothed plate (3). The eccentric wheel (4) in the large-diameter segment of the radially eccentric area forms a clearance fit with the shaft shoulder (22) and the axis central hole (32). The wedge-shaped block (6) is disposed in the radially eccentric area, and clearances between the eccentric wheel (4) and the axis central hole (32) of the outer toothed plate (3) and between the engaged teeth are eliminated by the wedge-shaped block (6) and the eccentric wheel (4) under a circumferential force exerted by an elastomer (7). The seat recliner has extremely high and stable strength performance. A seat having the seat recliner is also provided.
