<p>A magnetorheological fluid shock absorber that uses a magnetorheological fluid having a viscosity includes: a tubular cylinder formed from a non-magnetic material and having the magnetorheological fluid sealed into an inner periphery thereof; a piston formed from a non-magnetic material and disposed in the cylinder to be free to slide at an interval, through which the magnetorheological fluid can pass, relative to the inner periphery of the cylinder; a piston rod to which the piston is connected; and a magnet portion attached to cylinder in order to apply a magnetic field to an interior of the cylinder. The magnet portion includes a permanent magnet having an inner peripheral shape that aligns with an outer periphery of the cylinder; and a ring member formed from a magnetic material and disposed on an outer peripheral side of the permanent magnet.</p> |
