Abstract

See full text

A steering damper is configured to adjust a damping force of a rotor covered by a lower casing and an upper casing by changing the viscosity of a magnetic fluid with an electromagnet. Since a magnetic fluid chamber is provided with a volume compensating unit, even when the volume of the magnetic fluid expands, or air entrainment occurs, air bubbles lighter than the magnetic fluid are collected in the volume compensating unit. Thus, characteristic variations of the steering damper due to volume expansion or air entrainment of the magnetic fluid are prevented.
