A stabilizer is provided for a motor vehicle with two shafts (), which extend in the transverse direction of the vehicle, can be coupled with one another via a mechanical coupling () and are in functional connection with wheels of the motor vehicle with their ends facing away from the coupling (). A first shaft is connected to a first coupling portion designed as a locking disk and a second shaft is connected to a second coupling portion, which cooperates with the locking disk () and is designed as a locking device (). The locking device () has a ratchet element (A,B), which can be actuated by a cam disk () that can be rotatingly driven by a drive source () against a spring means, and a blocking member (A,B) connected thereto, via which the shafts are connected in such a way that they rotate in unison in a first end position of the cam disk () because of a positive connection between the locking disk and the blocking member (A,B), and the positive connection is abolished in a second end position of the cam disk (). The ratchet element (A,B) is designed according to the present invention with two lever arms (AAB-B), which are rigidly connected to one another and are designed with a contact area (AA,AA,BA,BA) each, via which the lever arms (AABB) are in contact with the cam disk ().
