Abstract: The present invention relates to a sliding clutch made of plastic material, which is especially suitable for the use in adjustment drives for vehicular exterior mirrors. The sliding clutch thereby comprises a first clutch part and a second clutch part, wherein the first clutch part and the second clutch part abut one another with planar faces in such a way that they are into engagement with one another up to a maximum torque only because of static friction. In this way, a sliding operation without rattling noises can be guaranteed. For achieving this safety function by means of which no force or torque transmission occurs from a predetermined torque range, no further mechanical components or additional electrical controls are required.
