Abstract:
An actuator of a steering system having a housing (2), a spindle drive arranged in the housing (2) which includes an axially movable spindle (5) that engages with a spindle nut (6) mounted in a fixed position. The spindle has at least one fastening end (8, 9), and at least one bearing journal (10, 11) arranged and able to move in the housing (2). The journal is connected to the at least one fastening end (8, 9) of the spindle (5), with at least one joint connection component (3, 4) which is arranged outside the housing (2) and is connected to the at least one bearing journal (10, 11). The at least one bearing journal (10, 11, 110) has a constriction (10v, 11v) that forms a flexible zone (122).
