Zusammenfassung:The invention provides an eccentrically swinging reducer device capable of further shortening time needed by running-in. According to the eccentrically swinging reducer device (G), an inner gear (30) has an inner gear main body (32), a pin groove (34) formed in the inner gear main body (32), and an outer pin that is a pin member (36) disposed in the pin groove (34). The RMS roughness (Rq) of the surface of the pin groove (34) is less than 1.6 [mu]m. Or the sum of the rank difference (Rk) of a core in the surface of the groove pin (34) and the average depth (Rvk) of a protruding portion is less than 5.0 [mu]m.
