Steering mechanism for vehicles equipped with power steering system

A steering mechanism for a vehicle equipped with a power steering unit producing an increased steering reactive force in proportion to vehicle speed and a resilient element interposed in a path of torque transmission between a steering wheel and said power steering unit, comprising:

• a damper means provided between two relatively rotatable members operably associated with each other through said resilient element, whereby torsional vibrations of a first one of said members disposed on the side of said steering wheel, caused by the resiliency of said resilient element and the moment of inertia of said steering wheel, are attenuated;
• said damper means comprising two elements adapted to produce a frictional force when one of said elements rotates relative to the other of said elements;
• and
• said two elements of said damper means comprising a ring and a cover fitted on the outer periphery of said ring.
