Abstract: A drive mechanism having a drive motor that rotatably drives a threaded spindle against a specific braking force generated by a pretensioned spring of a friction brake arrangement. The drive motor and the threaded spindle are arranged coaxially in a housing tube of the drive mechanism, and components of the friction brake arrangement are arranged in a tubular brake housing, which is arranged in an axially and rotationally fixed in the housing tube. A first end of the brake housing has one or more radially inwardly directed first stop shoulders and at a second end of the brake housing has one or more radially inwardly directed second stop shoulders. The brake housing has at its first end a radially circumferential ring with one or more radially resilient spring arms extending axially toward the second end, at the free ends of which spring arms are arranged the second stop shoulders.
