Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a grease composition which maintains a satisfactory lubrication state for a long period of time, even when water is mixed, to suppress while texture separation and corrosion, and a hub unit bearing for vehicle which is less likely to cause white texture separation and corrosion, even when used in such an environment that water is mixed, and thus has a prolonged service life.SOLUTION: The grease composition for hub hit bearing includes: a base oil mainly composed of at least one of mineral oil and synthetic oil; a thickener, and a separation inhibitor. The separation inhibitor is an amine-based rust inhibitor including oleic acid and a salt of dicyclohexylamine, with the content thereof being 0.1-5 mass%. The hub unit bearing includes the grease composition sealed therein.
