Abstract
A lubricating grease composition containing a base oil having a kinematic viscosity of 10 mm2/s or more and 60 mm2/s or less at 40° C.; a thickener containing at least one soap selected from a metal soap and a metal complex soap; and a solid lubricant containing porous polyamide particles. An amount of the porous polyamide particles blended is 1% by mass or more and 20% by mass or less based on a total mass of the lubricating grease composition.
