Disclosed is an electric power steering apparatus in which an electric motor for producing a steering assist force is provided in a steering column. Vibration from the electric motor is transmitted to a member such as a knee protector, for example, supported on the steering column through a bracket. A dynamic damper for restraining resonance of the member to which the vibration is transmitted is provided in the bracket.

Electric power steering apparatus

A screw member is screwed into a spool which is axially movably inserted into a housing. The opening of the throttling portion of a variable throttle valve is varied according to the axial shifting of the spool according to the rotation of the screw member. The centerline of the screw member is eccentric to the centerline of the spool. The eccentricity prevents the spool from rotating together with the screw member.
