Abstract
The present invention aims to provide an inorganic reinforced polyamide resin composition that achieves incompatible mechanical properties, i.e., high stiffness and impact resistance (high toughness), has excellent flowability, and further has excellent long-term wear resistance (high sliding performance) to an inorganic fiber reinforcing material used as a sliding counterpart material. An inorganic reinforced polyamide resin composition containing: 10 to 55 mass % of a crystalline polyamide resin (A); 1 to 20 mass % of an amorphous polyamide resin (B); 40 to 70 mass % of an inorganic reinforcing material (C); and 0.5 to 10 mass % of a modified polyolefin resin (D) having a reactive functional group that is capable of reacting with a terminal group and/or a main-chain amide group of a polyamide resin, characterized in that a blending mass ratio between the components (A) and (D) satisfies 0.01≤(D)/(A)≤0.2, and a blending mass ratio between the components (A) and (B) satisfies 0.05≤(B)/(A)≤0.7.
