Claims

[Scope of utility model registration request]

A first shaft and a second shaft constituting a steering shaft are coaxially connected to each other by a torsion bar, and when the relative rotational displacement between these two shafts reaches a predetermined value, the steering shaft is rotated by driving an electric motor. In the electric power steering device, a slider that can slide only in the axial direction is attached to one of the two shafts, and a shaft is attached to one end of the slider to the other of the two shafts. A fitting convex part or a fitting recess is provided opposite to a fitting concave part or a fitting convex part provided in the direction and capable of being fitted thereto, and when the vehicle speed is less than a predetermined value, the fitting concave part and the fitting convex part are engaged. An electric motor, characterized in that it is provided with a drive mechanism that drives the slider so as to release the fitting between the slider and the fitting recess and the fitting protrusion when the vehicle speed reaches a predetermined value. Steering device.
