Abstract
A colloidal damper disposed between two members for damping a relative movement of the two members, including: (I) a cylinder device including a housing and a piston which are connected to one and the other of the two members and which define a chamber; (II) a colloidal-solution sealed body accommodated in the chamber and including: (A) a colloidal solution in which are mixed a first working fluid and porous bodies each having pores; and (B) a hermetically sealed container which has flexibility and which hermetically seals the colloidal solution contained therein; and (III) a second working fluid contained in the chamber together with the colloidal-solution sealed body, wherein the colloidal damper is configured to damp the relative movement of the two members by the inflow and the outflow of the first working fluid into and out of the pores upon the relative movement of the two members.
