An adjustment device for adjusting an optically relevant component of a vehicle headlamp, comprising - an actuator element, which is displaceable along a displacement axis (x) by means of an actuator motor, - a transmission element connected to the actuator element, designed for displacement along the displacement axis (x), and mounted rotatably about the displacement axis (x), - an adjustment element mechanically engaged with the transmission element by means of a connection (8b, 3b), wherein the adjustment element is designed to act on the optically relevant component, and - a rotary element, which is designed to rotate the transmission element and which is mounted rotatably about the displacement axis (x), wherein the connection (8b, 3b) connecting the transmission element to the adjustment element is designed to convert a rotary movement of the transmission element into a sliding movement of the adjustment element along the displacement axis (x), wherein the transmission element is received at least in part in a substantially circular opening of the rotary element arranged concentrically with the displacement axis (x), characterised in that the transmission element has resilient means which are arranged at the periphery of a virtual circle arranged concentrically with the displacement axis (x) and extend along the displacement axis (x), wherein the resilient means have protrusions which are designed to engage in corresponding indentations arranged within the opening, wherein the resilient means are preferably formed in a tongue-like manner, wherein the protrusions are preferably embodied in the form of axis-parallel pins and the indentations corresponding thereto are preferably embodied as axis-parallel grooves. - an actuator element, which is displaceable along a displacement axis (x) by means of an actuator motor, - a transmission element connected to the actuator element, designed for displacement along the displacement axis (x), and mounted rotatably about the displacement axis (x), - an adjustment element mechanically engaged with the transmission element by means of a connection (8b, 3b), wherein the adjustment element is designed to act on the optically relevant component, and - a rotary element, which is designed to rotate the transmission element and which is mounted rotatably about the displacement axis (x), wherein the connection (8b, 3b) connecting the transmission element to the adjustment element is designed to convert a rotary movement of the transmission element into a sliding movement of the adjustment element along the displacement axis (x), wherein the transmission element is received at least in part in a substantially circular opening of the rotary element arranged concentrically with the displacement axis (x), characterised in that the transmission element has resilient means which are arranged at the periphery of a virtual circle arranged concentrically with the displacement axis (x) and extend along the displacement axis (x), wherein the resilient means have protrusions which are designed to engage in corresponding indentations arranged within the opening, wherein the resilient means are preferably formed in a tongue-like manner, wherein the protrusions are preferably embodied in the form of axis-parallel pins and the indentations corresponding thereto are preferably embodied as axis-parallel grooves.
