Abstract
A grease includes abase oil and a thickener. The base oil is poly-α-olefin. The thickener is a soap. A viscous transition stress at 25° C. is 300 Pa or more, and a viscous transition stress at 100° C. is 40 Pa or less. A shear viscosity at 25° C. and at a shear rate of 0.1 s−1 is 1.6×106 mPa·s or more, and a shear viscosity at 100° C. and at a shear rate of 10 s−1 is 1.1×104 mPa·s or less.
