PROBLEM TO BE SOLVED: To improve a sliding performance of a synthetic resin nut against a metal screw shaft while securing a mechanical strength of the nut by a lower-cost method than the conventional example. SOLUTION: 80 mass% or more of a base oil is composed of at least one kind selected from a polyαolefin oil or a mineral oil and the kinetic viscosity of the base oil is 18 mm<SP>2</SP>/s-411 mm<SP>2</SP>/s at 40°C and the slide screw is characterized by that the slide screw is lubricated with a grease including an additive composed of at least one kind selected from polyolefin, wax, and fluorine resin by a ratio of 1.0 mass% -10.0 mass% and having a worked penetration of 220-330.
