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.

Vehicle steering apparatus

An electric motor having a rotation shaft includes a motor housing into which the electric motor is accommodated, at least one pair of rolling bearings positioned in the motor housing and rotatably supporting both ends of the rotation shaft, and a displacement restriction member provided inside the motor housing and restricting a displacement of the rolling bearing in an axial direction of the rolling bearing. Each rolling bearing includes an inner race, an outer race, and rolling elements rotatably supported between the inner race and the outer race. The inner race is press fitted without any gaps onto an outer peripheral surface of the rotation shaft, and the outer race is press fitted without any gaps into a bearing attachment portion provided inside the motor housing.
