Embodiment Construction

[0029] figure 1A partially sectioned central bearing device 1 for a starter device, in particular a starter motor for starting an internal combustion engine, is shown in a perspective view. The intermediate support device comprises an approximately pot-shaped intermediate support element 2 with an annular engagement area 3 . The toothing area 3 comprises a substantially annular base section 4 and a plurality of toothing sections 5 which are designed as teeth 5 a protruding radially inwards from the base section 4 . Various formations 5 b protrude radially outward from the base section 4 . Integrated in the engagement region 3 is an approximately annular reinforcement 6 which forms a means for increasing the stability of the engagement. In the axial direction of the intermediate support, the reinforcement body 6 extends approximately at right angles to the bottom of the basin-shaped intermediate support 2 over approximately the entire width of the engagement section 5 . In t...
