PROBLEM TO BE SOLVED: To reduce a weight of a suspension including a magnetic viscous fluid buffer.SOLUTION: A suspension includes a magnetic viscous fluid buffer D1 which includes a piston 3 held by a piston rod 2 coming in and out to a cylinder 1, and defining two chambers r1, r2 formed in the cylinder 1, a magnetic viscous fluid charged into the two chambers r1, r2 and changing its viscosity by action of a magnetic field, a passage L for communicating the two chambers r1, r2, and viscosity adjusting means 4 for adjusting the viscosity of the magnetic viscous fluid passing through the passage L, and in which the magnetic viscous fluid is sealed, and the suspension is disposed between a car body and a wheel. The suspension further includes a tube member T composed of an outer tube t1 connected to a car body side, and an inner tube t2 connected to a wheel side and coming in and out to the outer tube t1, and accommodating the magnetic viscous fluid buffer D1, a lubricating liquid accommodated in the tube member T, and a seal member C1 blocking between the inner tube t2 and the magnetic viscous fluid buffer D1, and preventing intrusion of the lubricating liquid to the wheel side. |
