The diaphragm spring comprises at least two perforated discs internally. The shielding cap and bush are grounded to the ignition distributor housing via plastic deformation of the bush to complementally configure same to the diaphragm spring. The shielding cap and distributor cap are held onto the distributor housing via at least two cap screws, the screws securing the bushes to the housing, and an undetachable contact is effected between the bush and the perforated disc by such plastic deformation.
