The invention starts from an actuating drive ( 10 ) with an electric motor ( 12 ), which drives an output shaft ( 32 ) via a toothed wheel gear ( 14 ) in a planetary design, which includes a first housing-mounted central wheel ( 16 ) and a second rotatable central wheel ( 18 ), whereby both central wheels ( 16, 18 ) each form gear steps with different step-down ratios with at least one planet wheel ( 20, 22 ) and the planet wheel ( 20 ) belonging to the first central wheel ( 16 ) is connected to the planet wheel ( 22 ) belonging to the second central wheel ( 18 ) in a torque-proof manner. It is proposed that the electric motor ( 12 ) drive a planet carrier ( 26 ) on which the planet wheels ( 20, 22 ) are pivoted.
