In an adjusting device for displacing individual elements ( 2 ) of optical systems or of measuring systems in which the element to be displaced is movable on a base ( 1 ) along a predetermined direction (x) by means of a piezoelectric actuator arrangement ( 21, 22 ) which is supported by the element ( 2 ) and which is constructed and controllable in such a way that it exerts shock pulses on the element ( 2 ) in order to carry out a stepwise movement of the element ( 2 ) on the base ( 1 ), the element ( 2 ) is arranged in a body ( 1; 27 ) which has an open or closed hollow cross section and is supported in a frictional engagement on this body, at least at one location, with the intermediary of a pretensioned spring device ( 8, 8' ).
