Abstract

PURPOSE: To improve the ignition property of rotary piston engine during its idling and light-load running, by improving a grounded electrode of a side metal and thereby suppressing the channeling and utilizing the advantages of a half-surface plug to the maximum extent.
CONSTITUTION: The end face 15a of the side metal 15 projects by 2mm or less from the end face 12a of an insulator 12. The grounded electrode 14 formed on the side metal 15 projects in the radial direction from the inside surface 15 of the side metal 15 so that a radial distance is set between the inside surface 14a of the grounded electrode 14 and the outside surface 12b of the insulator 12. The inside edge of the grounded electrode 14 is located outside in the axial direction at a distance of 0 to 1mm from the end face of the insulator 12
