Abstract: An ignition distributor which is driven by an engine includes a structural division between the engine block and ignition distributor and has a separable connection, which is embodied as a claw coupling. For corresponding operational parts dimensionally stable, self-lubricating and wear-resistant plastic is used at the force transfer points of the claw coupling. Thus, it is possible to operate the claw coupling in a dry-running manner which does not require an encapsulated lubrication.
