A starter drive for combustion engines has a motor on whose rotatable output shaft is mounted a pinion having freedom of rotation as well as axial displacement relative to the shaft. A motion-transmitting arrangement is provided, including a funnel-shaped motion-transmitting element rotatable with the shaft surrounding the same and located adjacent one end of the pinion with its open side facing the latter, and an elastically yieldable annular coupling member surrounding and fast with the pinion at the one end thereof and conically converging on its outer periphery towards the funnel-shaped element so that, when the coupling member is received in the latter, frictional motion-transmission will be established between the shaft and the pinion.
