The present invention relates to a vehicle steering apparatus. According to an embodiment of the present invention, the vehicle steering apparatus comprises: a steering operation unit in which a steering force is generated according to the operation by a driver; a control unit generating a first control signal for generating a steering assist force in response to the steering force generated from the steering operation unit; an intermediate shaft in which the steering operation unit is connected to one end thereof and a rack gear is connected to the other end thereof, and which transmits the steering force and the steering assist force to the rack gear; a motor unit generating the steering assist force by rotating the intermediate shaft in response to the first control signal transmitted from the control unit; and a rack gear which is connected to the other end of the intermediate shaft and controls the direction of vehicle wheels by using the steering assist force and the steering force transmitted through the intermediate shaft. The present invention has a structure in which the intermediate shaft and the motor unit are integrally combined and packaged, so that a gear device for connecting the intermediate shaft to the motor unit is not required, and has a simple structure, thereby reducing the weight of the vehicle.
