An actuating unit for an electromechanically actuatable disk brake for motor vehicles consists essentially of a drive unit ( 1 ), i.e., an electric motor ( 11 ); an actuating element ( 7 ), by means of which one ( 4 ) of two friction linings ( 4, 5 ) mounted with limited freedom of movement in a brake caliper can be brought into engagement with a brake disk ( 6 ); and a first and a second reducing gear ( 2, 3 ). An electronic controller ( 8 ), which serves to drive the electric motor ( 11 ), is assigned to the actuating unit. To realize an actuating unit of compact axial dimensions which is also optimally designed with respect to packaging, at least part of the electronic controller ( 8 ) is mounted between the electric motor ( 11 ) and the housing ( 25 ) which holds the second reducing gear ( 3 ).
