Abstract
A column-assist type electric power steering device () is provided with: a steering shaft (); a magnetostrictive type torque sensor () that detects a torque produced in the steering shaft (); and bearings () that rotatably support the steering shaft (). The magnetostrictive type torque sensor () includes a magnetostrictive film () disposed on an outer peripheral surface of the steering shaft (), and a detection unit () that is disposed opposite the magnetostrictive film () and that detects a change in permeability. The bearings () are installed at two locations in the axial direction of the steering shaft () in such a manner as to sandwich the detection unit ().
