摘要：PROBLEM TO BE SOLVED: To provide a configuration in which a differential ca can be integrated with a ring gear by casting while good strength property required as
vosthe ring gear is maintained, in a differential device component containing the differential ca formed to be able to accommodate a differential gear mechanism and the ring gear arranged to rotate integrally with the differential ca.SOLUTION: A differential ca and a ring gear are formed integrally without joint by cast steel in a differential device component (a ring gear integrated differential ca 12). The cast steel contains, silicon (Si) of 0.3 to 1.0 mass%, mangane (Mn) of 0.5 to 1.2 mass%, vanadium (V) of 0.1 to 0.5 mass%, stannum (Sn) of 0.01 to 0.05 mass%, chromium (Cr) of 0.1 to 1.5 mass%, copper (Cu) of 0.2 to 1.0 mass%, and the balance iron (Fe) with inevitable impurities.
