The problem of providing a cylinder/piston unit which can be installed in a relatively space-saving manner, in particular, for use in a master/slave arrangement is solved by virtue of the fact that a first, outer hydraulic cylinder (2) is provided, in which a first piston (6) is mounted sealingly with respect to the cylinder inner wall of the first hydraulic cylinder (2) and longitudinally movable in the latter, and the first piston (6) supports a second, inner hydraulic cylinder (3), in which a second piston (9) is mounted sealingly with respect to the cylinder inner wall of the second hydraulic cylinder (3) and longitudinally movable in the latter. The second, inner hydraulic cylinder (3) supports a piston rod (10), and the piston rod (10) is connected at the end thereof which is remote from the second piston (9) to an end (4) of the outer hydraulic cylinder (2).
