Abstract
An electric power steering system () includes a tubular sensor housing () which accommodates a torque sensor (), a gear housing () which accommodates a speed reduction mechanism (), and an upper bearing () and a lower bearing () which rotatably support a steering shaft () on opposite sides of the speed reduction mechanism (). The gear housing () includes a tubular lower housing () supporting the lower bearing (), and an upper housing (). The upper housing () includes an inner tube (), an outer tube (), and an annular connection wall () connecting the inner tube () and the outer tube (). The outer tube () is press-fitted in the lower housing (). The inner tube () is press-fitted to an inner periphery () of a lower portion () of the sensor housing (), whereby the inner tube () has a reduced diameter. As a result, an outer ring () of the upper bearing () is tightly fitted and supported in the inner tube ().
