Abstract: A device for frictional inter-engagement between two mutually movable parts (13, 14). A lever mechanism exerts counter-directed pressing forces towards both parts to transfers movement between them. A lever (25) has a free lever end (27) contacted by a first (13) of the parts, and opposite to the free end a part-cylindrical convex surface (31) journalled in a part-cylindrical concave bearing surface (33). In order to eliminate the risk of jamming of the lever due to excessive surface pressure, it is journalled with rolling bodies, preferably cylindrical bodies (34).
