Provided is a vehicle steering system that is able to restrict a travel amount of a steered shaft in a housing, that is small and that has an excellent strength. The vehicle steering system is a steer-by-wire vehicle steering system (1) that converts rotative power of electric motors (21, 22) into a movement of a steered shaft (6) in an axial direction (X1) via a ball screw mechanism (23). One of contact portions (45, 46) at respective ends of a screw shaft (32) at an intermediate part of the steered shaft (6) passes through a rotor (26) based on a moving direction of the steered shaft (6) so as to contact a corresponding one of the corresponding stoppers (47, 48), thereby restricting a travel amount of the steered shaft (6). The stoppers (47, 48) are made of a material different from that of the housing and having a high strength. |
