Repelling force apparatus of power steering system for vehicle

A repelling force apparatus of a power steering system for a vehicle, said apparatus comprising:

• an exciting coil;
• a permanent magnet;
• and
• a pair of rotational ferromagnetic members including an inner member having a plurality of outwardly extending teeth and an outer member having a plurality of inwardly extending teeth, said outwardly extending teeth being radially aligned with respective ones of said inwardly extending teeth, said outwardly extending teeth and said inwardly extending teeth being formed in a trapezoidal shape, said outwardly extending teeth and said inwardly extending teeth having opposing facing surfaces of different sizes, wherein the opposing facing surfaces of said outwardly extending teeth face radially outwardly and the opposing facing surfaces of said inwardly extending teeth face radially inwardly so that the opposing facing surfaces of said outwardly extending teeth face the opposing facing surfaces of respective ones of said inwardly extending teeth.
