ABSTRACT OF THE DISCLOSURE A friction spring unit has a friction spring in- cluding a plurality of inner rings and outer rings whose conical surfaces cooperate with each other with interposition of a lub- ricant, and an outer casing element and an inner casing element which shield the friction spring from outside and inside, res- pectively. The rings of the friction spring which are located at axial ends of the latter are sealingly connected with the inner casing element and the outer casing element. This sealing connection may be performed by interengaging beads and grooves, or flange-like projections and supports. The casing elements may be formed as hoses or each may be composed of at least two telescopable sleeves. -1-
