PROBLEM TO BE SOLVED: To provide a grease composition for automotive electrical equipment capable of further suppressing seizure and peeling accompanied by white structure change even under high temperature and extremely low temperature of about -40 ° C, high speed, high load and high vibration, and such Provide rolling bearings for automotive electrical accessories that have long life and excellent stability even in difficult environments. SOLUTION: A base oil containing an aromatic ester oil, a thickener composed of an aromatic hydrocarbon group alone or a diurea compound composed of both an aromatic hydrocarbon group and an aliphatic hydrocarbon group, and an antioxidant. And a rust preventive agent and an anti-peeling additive, and an automotive electrical accessory grease composition, and a plurality of rolling elements between the inner ring and the outer ring so as to be freely rollable. Rolling bearing for automotive electrical equipment that contains a grease composition for machinery. [Selection] Figure 1 |
