The invention relates to a multiple screw driving machine comprising a plurality of individual screwdrivers which are arranged on a body or in a housing ( 8 ) and which each comprise a spindle or shaft ( 7 ) which is rotatably mounted in the housing and which at an outer front end carries a screw driving tool ( 10 ) for engagement with a screw means. Each of the screwdrivers are separately drivable by a common motor ( 1 ) via a driving wheel transmission comprising a primary driving wheel ( 5 ) for each screwdriver. The primary driving wheel ( 5 ) is rotatably but non-displaceably mounted on the shaft ( 7 ) of the respective screwdrivers whereas a driver element ( 14 ) is non-rotatably but displaceably mounted on the shaft ( 7 ) and is displaceable with the aid of an operating means ( 16 ) towards and away from the primary driving wheel ( 5 ). The primary driving wheel ( 5 ) and the driver element ( 14 ) each have mating and mutually facing engagement means ( 19, 20 ).
