An electric power steering apparatus is disclosed. The apparatus features a first shaft and a second shaft connected by an elastic member. A first detecting member is coupled to the second shaft, and made of magnetic material with a plurality of radial notched portions defining a number of slots. A pair of second detecting members are coupled to the first shaft and positioned on both sides of the first detecting member, and made of conductive and non-magnetic material with a plurality of radial notched portions defining a like number of slots. A pair of detecting coils are axially positioned on both sides of a set of the first and second detecting members. A housing accommodates the first and second detecting members, the detecting coils, and holds yokes in a fixed position. The largest outer diameter of the first shaft is smaller than each of the inner diameters of the first detecting member, the second detecting member and the yokes, thereby improving the assembling of the electric power steering apparatus.
