PURPOSE:To ensure charging even if a plug is stained by providing a gap between a secondary-voltage introducing part of an ignition coil in a distributor and an electrode of a rotor head for removing this gap at the high revolution of a rotor. CONSTITUTION:When the revolution of an engine, that is, the revolution of a rotor head 3 is low, a fixed gap is maintained between a movable electrode 7 and a secondary-voltage introducing part 5 of an ignition coil. When the number of revolutions of an internal-combustion engine is increased up to areas of medium or high revolution, the number of revolutions of the rotor head 3 is also increased accordingly, and the movable electrode 7 is moved to the outer circumference against an equalizer spring 8 by the centrifugal force of this revolution to be in contact with the secondary-voltage introducing part 5 of an ignition coil. This construction permits to add a high voltage between electrodes of an ignition plug for sparking even if the plug is stained and lowered in its insulating resistance, and improve the starting capacity of the internal-combustion engine. |
