Abstract
Provided is a particle-containing grease composition that can efficiently improve friction and wear resistance properties with a small added amount and exhibits excellent friction and wear resistance properties even when a clearance and the surface roughness of the friction surface in sliding parts are extremely small. The particle-containing grease composition includes base oil, a thickener, and molybdenum disulfide particles, in which a median diameter Dof the molybdenum disulfide particles determined by a dynamic light scattering method is 10 nm or more and less than 450 nm.
