In order to reduce vibration and improve durability at a low cost through the reduction of induced thrust, such a grease is used that has SRV friction coefficient muh under a contact pressure of 2176 MPa in a range from 0.060 to 0.080 and decreasing rate of SRV friction coefficient mu1 under a contact pressure of 3954 MPa with respect to the friction coefficient muh, namely (muh-mu1)/muhx100%, in a range from 40 to 60%. The outer joint member 1 is filled with this grease.
