トンエンジン。[Claims for Utility Model Registration] In a rotor piston engine in which a spark plug is installed in a plug mounting hole on the leading side formed in a rotor housing, the spark plug is connected to a center electrode and a predetermined distance from the center electrode. The spark plug is constructed of a semi-creeping spark plug having a side electrode surrounding the side electrode, and the opening of the plug mounting hole on the working chamber side is smaller than the outer diameter of the side electrode, and the inner diameter of the electrode is smaller than the outer diameter of the side electrode. A rotary piston engine characterized in that the size is set as above, and the tip of the side electrode is brought into contact with a stepped portion that is a connecting portion between the diameter of the plug mounting hole and the diameter of the opening.
