PROBLEM TO BE SOLVED: To achieve a reduction in vibration by a reduction of induced thrust and an improvement in durability at low costs. SOLUTION: A grease which has an SRV friction coefficientμh under a surface pressure of 2176 MPa of 0.060-0.080 and a lowering rate of an SRV friction coefficientμ1 under a surface pressure of 3954 MPa to the SRV friction coefficientμh, (μh-μl)/μh×100%, of 40-60% is used. This grease is enclosed in outer joint member 1. |
