An adjusting device for a disc brake, especially a pneumatically operated disc brake, is used for rotating and thus axially moving at least one rotary spindle that is provided with internal teeth composed of one or several axially extending grooves. The adjusting device includes an output bush that is provided with external teeth which engage into the internal teeth of the rotary spindle, as well as a monolithic or multipart release spindle. The release spindle axially penetrates the adjusting device and is used for manually releasing the same. The spindle is disposed and/or mounted in such a way that rotations of the spindle below a threshold torque, which are caused by vibrational stress during operation of the disc brake, are prevented. The adjusting device is characterized in that the spindle or a part that is connected to the spindle in a torsion-proof manner is also provided with external teeth which engage directly into the internal teeth of the rotary spindle as well.
