Provided is a vehicle steering apparatus capable of predicting failure while protecting a clutch device. The vehicle steering apparatus includes a turning device for turning steered wheels of a vehicle, and a steering device having a steering reaction force actuator for providing reaction force to assist user's steering of a steering wheel. A clutch device is provided between the steering device and the turning device to perform operation to mechanically cause a connection state or a disconnection state between the steering device and the turning device. Further, between the steering reaction force actuator and the clutch device, a mechanical fuse is arranged that twists and deforms by an input of an excessive load to prevent the load from being transmitted to the clutch device. A scribing line is drawn on the side surface portion of this mechanical fuse.
