LUBRICATING GREASE COMPOSITION FOR VEHICULAR ELECTRIC COMPONENT, CLUTCH MECHANISM AND STARTER

摘要

PROBLEM TO BE SOLVED: To provide lubricating grease for vehicular electric component which has excellent extreme pressure performance, durability and torque transmission capability without using a chlorine-based extreme pressure additive and a sulfur-based additive; a clutch mechanism using the lubricating grease for vehicular electric component; and a starter provided with the clutch mechanism.SOLUTION: A lubricating grease composition for vehicular electric component contains: (A) a straight silicone oil that is a base oil; (B) alkyl naphthalene; and (C) a modified silicone oil not corresponding to (A), and is free from a chlorine-based extreme pressure additive and a sulfur-based additive.
