Abstract

PURPOSE: To improve the ignition of an ignition device inserted into the plug hole perforated at a casing with a semi-creeping plug at the engine idling and low loading time for long period without losing the features of the plug.
CONSTITUTION: This ignition device consists of an insulator 13 with a centrl electrode 12 at the center, side brackets 15 surronding the outer periphery of the insulator 13 with a grounding electrode 15 formed at the end thereof, and a semi-creeping plug 10 inserted into a plug hole 11 forming creeping gap gS formed at the end surface of the insulator 13 and an air gap ga formed between the outer periphery of the insulator 13 and the grounding electrode 16 to thereby from spark gap. A plurality of circumferential slits 14 formed to cut into the ends of the brackets 15 toward inwardly axial direction in the device for a rotary piston engine thus constructed. The electrode 16 formed at the portion provided with no slit 14 is radially projected in predetermined length to be disposed axially outwardly from the end of the insulator 13
