Abstract

The starting device, particular a freely disengaging starting device, has an electric motor, the rotor of which drives a driven shaft which has a pinion for driving the gear ring of an internal combustion engine, in which the driven shaft end section carrying the pinion is supported in a face wall of the housing. For a compact structural form, in particular a short form, the driven shaft (6) is supported with its other end (23), via a first bearing (needle bearing 37) in a central aperture (166) of a free-wheel outer ring (35), the surface (164) of which is supported via a second bearing (deep groove ball bearing 38) on the housing (2) of the starting device (1). The associated end (25) of a rotor shaft (17) of the starter rotor (5) is supported via a third bearing (needle bearing 31) on the end section of the driven shaft (6) which lies in the interior of the housing (2).
