Abstract: The present disclosure relates to a resin composition for vehicle parts, a vehicle part manufactured using the resin composition, and a method of manufacturing the vehicle part. Ultra-high molecular weight siloxane and an inorganic filler are mixed with an alloy resin of polyamide and polyethylene at an optimal rate in order to improve friction resistance and wear resistance while maintaining excellent impact resistance and low hygroscopicity. When a vehicle part is manufactured using the resin composition, it is possible to eliminate the application of silicone-based oil or to remarkably reduce the amount of silicone-based oil that is used, whereby it is possible to reduce manufacturing costs. Furthermore, ingredients that are harmful to human beings, such as POM, are not included, whereby it is possible to improve the quality of air in a vehicle.
