Abstract
A suspension unit includes a lower frame and an upper frame vertically movably mounted on the lower frame via a link mechanism. The suspension unit also includes a magneto-spring unit for resiliently supporting the upper frame relative to the link mechanism. The amount of motion of the magneto-spring unit is smaller than that of the suspension unit, making it possible to provide a relatively compact suspension unit having a large stroke.
