PROBLEM TO BE SOLVED: To provide a grease for constant velocity joint reduced in abrasion and friction and capable of preventing occurrence of vibration, and a constant velocity joint in which the grease is sealed. SOLUTION: The grease for constant velocity joint comprises an alkali metal salt of molybdic acid as an essential component in a base grease obtained by formulating a base oil with a thickening agent and the thickening agent is a diurea compound represented by formula (1): R<SP>1</SP>-NHCONH-R<SP>2</SP>-NHCONH-R<SP>3</SP>(wherein R<SP>1</SP>and R<SP>3</SP>are each a 4-24C straight-chain alkyl group or a cyclohexyl group and R<SP>1</SP>and R<SP>3</SP>may be the same or different and R<SP>2</SP>is a 6-15C aromatic hydrocarbon group) and and the grease for constant velocity joint is sealed in the constant velocity joint.
